INTRODUCTION: Acute transverse myelitis (ATM) is a rare disorder (1-8 new cases
per million of population per year), with 20% of all cases occurring in patients
younger than 18 years of age. Diagnosis requires clinical symptoms and evidence
of inflammation within the spinal cord (cerebrospinal fluid and/or magnetic
resonance imaging). ATM due to neuroborreliosis typically presents with
impressive clinical manifestations. CASE PRESENTATION: Here we present a case of
Lyme neuroborreliosis-associated ATM with severe MRI and CSF findings, but
surprisingly few clinical manifestations and late conversion of the
immunoglobulin G CSF/blood index of Borrelia burgdorferi sensu lato.
Clinical symptoms and signs of neuroborrelial ATM may be minimal, even in cases
with severe involvement of the spine, as shown by imaging studies. The CSF/blood
index can be negative in the early stages and does not exclude Lyme
neuroborreliosis; if there is strong clinical suspicion of Lyme
neuroborreliosis, appropriate treatment should be started and the CSF/blood
index repeated to confirm the diagnosis.

Lyme neuroborreliosis (LNB) is the most frequent tick-borne infectious disease of the central nervous system. In acute LNB and the rare chronic state of infection, patients can experience cognitive deficits such as attention and memory disturbances. During LNB, single compounds of Borrelia burgdorferi sensu lato are released into the subarachnoid space.To investigate the pathogenesis of neurologic dysfunction in LNB, we determined that the outer surface protein C (OspC), a major virulence factor of B. burgdorferi, stimulated mouse microglial cells in a dose-dependent manner to release nitric oxide (EC50 = 0.24 mg/L) in vitro. To mimic pathophysiologic conditions of long-term release of this bacterial component in vivo, we treated C57BL/6 mice with recombinant OspC from Borrelia garinii or buffer by intraventricular infusion and tested them for behavioral deficits. After 4weeks, brains were examined by routine histology and immunohistochemistry. Assessment of spatial learning and memory of treated mice during OspC exposure did not reveal significant differences from controls. Continuous exposure to intrathecal B. burgdorferi OspC led to activation of microglia and axonal damage without demonstrable cognitive impairment in experimental mice.
These results suggest that long-term intrathecal exposure to OspC resulted in axonal damage that may underlie the neurologic manifestations in chronic LNB.

Borrelia burgdorferi, a great chameleon: know it to recognize it!

Department of Public Health Sciences, Sapienza University of Rome, Rome, Italy. firstname.lastname@example.org
Borrelia burgdorferi is a spirochaete that can penetrate the blood-brain barrier in early infection and can cause endothelial damage other than central nervous system lesions. We describe a clinical case of neuroborreliosis that occurred in the absence of classical erythema migrans or arthralgia. Magnetic resonance imaging findings compatible with simil-vasculitis and demyelinating lesions associated with the presence of anti-B. burgdorferi antibodies in the plasma or cerebrospinal liquid is an indication for antimicrobial treatment against B. burgdorferi. An early diagnosis and a prompt establishment of an adequate antibiotic treatment is needed for a successful recovery.

"Borrelioosissa esiintyy yleisesti neurologisia ongelmia sillä bakteerin erittämät neurotoksiinit sitoutuvat rasvakudoksiin. Rasvakudosta on runsaasti mm aivoissa ja äärihermostossa. Neurotoksiinit voivat aiheuttaa äkillisen kuuroutumisen, kasvohermohalvauksen, Parkinsonin oireet, MS oireet, hermotulehduksia, kroonista kipua ym neurologisia ongelmia. Kissankynsi näyttäisi korjaavan immuunipuolustuksen toimintaa, tuhoavan mikrobeja ja estävän hermomyrkkyjen vaikutuksen soluihin, entsyymeihin ja hormoneihin.
Tri Joanne Whitakerin potilailla lähes jokaisen Parkinson oireita sairastavan borrelia-testi on ollut positiivinen. Tri Louis Romero kertoo kolmen Parkinson potilaansa olevan lähes oireettomia (99%) TOA vapaan kissankynsihoidon jälkeen.
Larry Powers sairastui Parkinson taudin oireisiin v.1990. Hän käytti taudin hoidossa yleisesti käytettyä Sinemet hoitoa kahdeksan vuoden ajan. Hoidosta huolimatta hänen tilansa heikkeni heikkenemistään. Lopulta hän joutui pyörätuoliin eikä kyennyt syömään ilman apua. Kun hän sai tietää että Parkinson voi johtua borrelia-bakteerista, hän alkoi käyttää TOA vapaata kissankynttä. Kolmessa viikossa hänen tilansa parani niin paljon että hän pääsi pois pyörätuolista ja kävi kalastamassa.
Tom Coffey sai ALS diagnoosin 34-vuotiaana. Kesäkuussa 2001 hän ei kyennyt nielemään sylkeä eikä syömään. Hänelle laitettiin ruokintaletku. Hänen painonsa putosi nopeasti. Tom konsultoi Borrelioosiin erikoistunutta lääkäriä. Tämä aloitti suonensisäisen Tomille antibioottihoidon (Rocephalin) ja Tom tuli kuntoon."
Dr. Joanne Whitaker relates that nearly every patient with Parkinson?s Disease (PD). has tested positive for Bb. Dr. Louis Romero reports that 3 patients with PD are 99 % better after TOA-free cat?s claw (Uncaria tomentosa) therapy.
Case Reports Illustrating The Critical Importance Of Establishing The Diagnosis Of Lyme Disease
Case 1 Larry Powers, a former Mr. America in 1962, became ill with the symptoms of Parkinson?s Disease in 1990. Sinemet therapy was taken for eight years but he gradually became worse. He became confined to a wheel chair and required help with eating. After learning that Lyme Disease might be causing his symptoms of PD he started taking TOA free cat?s claw (Uncaria tormentosa). Within three weeks he was out of his wheelchair and fishing for 100 pound tarpon.
Case 2 Tom Coffey at age 34 developed diplopia, severe hypertension uncontrolled by drugs, and impaired balance. A diagnosis of amyotrophic lateral sclerosis was made. Surgery was performed to correct the diplopia. By June 2001 he was unable to swallow saliva and feeding tube nutrition was begun. His weight had fallen by 100 pounds. Nutritional support from the tube feedings produced slow resolution of the swallowing problem. Consultation with a Lyme expert uncovered the history of a bulls-eye rash after a tick bite. Therapy with Rocephin led to complete recovery.
Case 3 A young male college student developed such severe cognitive difficulties he was forced to drop out of school. A RIBb test was positive for LD and he resumed a normal life after receiving 4 months of antibiotic therapy...
.....Lyme Disease frequently exhibits neurologic abnormalities because the Bb neurotoxins are drawn to the fatty tissue found in the brain and peripheral nerves. As a consequence sudden deafness, Bells palsy, Parkinson?s Disease, Multiple Sclerosis, reflex sympathetic dystrophy, peripheral neuritis, chronic pain, and a multitude of other neurologic disorders may appear.
....The Influence of Toxins from Bb On The Symptoms and Course of Lyme Disease
Nuorilla Parkinsonin oireisiin kuolleilla tehdyissä ruumiinavauksissa on toistuvasti huomattu että aivovauriot eivät ole samanlaisia kuin tyypillisissä Parkinson tapauksissa vanhemmilla henkilöillä. Osa potilaista on saanut vuosikausiksi virheellisen Parkinson, ALS, MS diagnoosin. Osa on saanut nopean avun kissankynsivalmisteesta. Nopea apu ei selity immuunipuolustuksen vahvistumisella eikä valmisteen bakteereja tuhoavasta ominaisuudesta. Borrelia-bakteeri erittää erilaisia hermomyrkkyjä. Kissankynsi (Uncaria tomentosa) näyttäisi estävän hermomyrkkyjen vaikutuksen rasvakudoksiin.
Autopsy examinations of young persons (30s) dying from what appeared to be Parkinson?s disease PD have frequently failed to confirm the basal ganglion damage that would be expected in the classic PD seen in the elderly. Some patients with illnesses of many years duration misdiagnosed as Amyotrphic Lateral Sclerosis, Multiple Sclerosis, and Parkinson?s Disease have made incredible recoveries within periods as short as 24 to 72 hours when placed on TOA-free uncaria tormentosa (cat?s claw) for LD.. This rapid response could not rationally be attributed to improved immune function or bacteriocidal effects on spirochetes. Bb is known to produce a group of neurotoxins. The most sensible explanation for this recovery lies in turning off or blocking the neurotoxic effects of Bb on the lipid containing structures that the Bb neurotoxins are attracted to (central nervous system, peripheral nerves, muscles, joints etc.). This sudden improvement appears to be the result of blockage and inhibition of the neurotoxins. The most important example of a ?Biotoxin Illness? appears to be Lyme Disease. Patients with symptoms of Parkinson?s Disease at a young age caused by neurotoxins would not be expected to show permanent structural destruction in the basal ganglia. These neurotoxins probably act at specific sites such as neurotransmitters-pre- and- post synaptic membranes, altering dopamine, serotonin, GABA, and acetylcholine molecules, thereby blocking surface membrane receptors of various kinds which would interfere with the proper action of enzymes, coenzymes and hormones. This is only one of the damaging mechanisms of action of the neurotoxins.
The TOA free form of cat?s claw (Samento) may have three direct beneficial effects in humans with LD:
Immune modulation (correcting immune dysfunction)
Direct broad spectrum anti-microbial effect on spirochetes. Quinovic acid glycosides found in TAO-free cat?s claw are similar to the quinilones widely used as antibiotics.
Blocking the adverse neurotoxic effects on cells, enzymes, and hormones
Whether the serious lack of energy and fatigue seen in LD are similar to the cyanate induced damage to the mitochondria?s ability to produce energy in the motor neurone found in amyotrophic lateral sclerosis or is due to failure of proper calcium channel function is not clear.

European neuroborreliosis: neuropsychological findings 30 months post-treatment.
Eikeland R, Ljøstad U, Mygland A, Herlofson K, Løhaugen GC
Eur J Neurol 2011 10 15
Background: The aim of this study was to compare neuropsychological (NP) functioning in patients with Lyme neuroborreliosis (LNB) 30 months after treatment to matched controls.
Methods: We tested 50 patients with LNB and 50 controls with the trail-making test (TMT), Stroop test, digit symbol test, and California Verbal Learning test (CVLT). A global NP sumscore was calculated to express the number of low scores on 23 NP subtasks.
Results: Mean scores were lower amongst LNB-treated patients than amongst controls on tasks assessing attention/executive functions: (Stroop test 4: 77.6 vs. 67.0, P = 0.015), response/processing speed (TMT 5: 23.4 vs. 19.2, P = 0.004), visual memory (digit symbol recall: 6.6 vs. 7.2, P = 0.038), and verbal memory (CVLT list B: 4.68 vs. 5.50, P = 0.003). The proportion of patients and controls with NP sumscores within one SD from the mean in the control group (defined as normal) and between one and two SD (defined as defi cit) were similar, but more LNB-treated patients than controls had a sumscore more than two SD from the mean (defined as impairment) (8 vs. 1, P = 0.014).
Conclusions: As a group, LNB-treated patients scored lower on four NP subtasks assessing processing speed, visual and verbal memory, and executive/attention functions, as compared to matched controls. The distribution of NP dysfunctions indicates that most LNB-treated patients perform comparable to controls, whilst a small subgroup have a debilitating long-term course with cognitive problems.

Lyme neuroborreliosis manifesting as an intracranial mass lesion.

Department of Surgery, University of Alabama, School of Medicine, Birmingham.
Lyme neuroborreliosis is one of the chronic manifestations of Lyme disease and is caused by the neurotropic spirochete, Borrelia burgdorferi. Two of the three stages of Lyme disease potentially involve the central nervous system: a second stage that may manifest as meningitis, cranial neuritis, or radiculoneuritis; and a third stage, or chronic neuroborreliosis, with parenchymal involvement. The tertiary stage may mimic many conditions, including multiple sclerosis, polyneuropathy, viral encephalitis, brain tumor, vasculitis, encephalopathy, psychiatric illness, and myelopathy.
We report a 10-year-old child with signs, symptoms, and radiological manifestations of intracranial mass lesions, without previously recognized manifestations of Lyme disease. This proved to be Lyme neuroborreliosis, documented by histological and serological examination, which responded well to antibiotic therapy. The need to establish a tissue diagnosis of intracranial mass lesions is emphasized, and the utility of a computed tomographic-guided stereotactic system for this purpose is discussed.

Published: 23 April 2012
Inflammation caused by the Lyme disease spirochete B. burgdorferi is an important factor in the pathogenesis of Lyme neuroborreliosis. Our central hypothesis is that B. burgdorferi can cause disease via the induction of inflammatory mediators such as cytokines and chemokines in glial and neuronal cells. Earlier we demonstrated that interaction of B. burgdorferi with brain parenchyma induces inflammatory mediators in glial cells as well as glial (oligodendrocyte) and neuronal apoptosis using ex vivo and in vivo models of experimentation.
In this study we evaluated the ability of live B. burgdorferi to elicit inflammation in vitro in differentiated human MO3.13 oligodendrocytes and in differentiated primary human oligodendrocytes, by measuring the concentration of immune mediators in culture supernatants using Multiplex ELISA assays. Concomitant apoptosis was quantified in these cultures by the in situ terminal deoxynucleotidyl transferase mediated UTP nick end labeling (TUNEL) assay and by quantifying active caspase-3 by flow cytometry. The above phenomena were also evaluated after 48 h of stimulation with B. burgdorferi in the presence and absence of various concentrations of the anti-inflammatory drug dexamethasone.
B. burgdorferi induced enhanced levels of the cytokine IL-6 and the chemokines IL-8 and CCL2 in MO3.13 cells as compared to basal levels, and IL-8 and CCL2 in primary human oligodendrocytes, in a dose-dependent manner. These cultures also showed significantly elevated levels of apoptosis when compared with medium controls. Dexamethasone reduced both the levels of immune mediators and apoptosis, also in a manner that was dose dependent.
This finding supports our hypothesis that the inflammatory response elicited by the Lyme disease spirochete in glial cells contributes to neural cell damage. As oligodendrocytes are vital for the functioning and survival of neurons, the inflammation and subsequent apoptosis of oligodendrocytes induced by B. burgdorferi could contribute to the pathogenesis of Lyme neuroborreliosis.

Borrelia valaisiana in Cerebrospinal Fluid
To the Editor: Lyme borreliosis is the most common tickborne human disease in the Northern Hemisphere. The incidence of the disease in not the same throughout Europe; in southern Europe, the incidence ranges from 43% in Croatia to 1.1% in Greece. Suspected borreliosis cases have been reported in Greece, none were confirmed. Ixodes ricinus, the principal tick vector of Borrelia burgdorferi in Europe, is found in northern Greece. A low prevalence of B. burgdorferi antibodies was found in healthy persons in Greece (1,2); a frequency of 7.3% was found in arthritis patients (1), while a frequency of 16.9% was found in patients with neurologic disorders (A. Papa, unpub. data).
Polymerase chain reaction (PCR) has been used to detect B. burgdorferi DNA in humans and to determine genospecies (3). Isolates found in the United States have constituted a homogeneous group. In Europe, five different genospecies from the original B. burgdorferi, now called burgdorferi sensu lato complex, have been described: B. burgdorferi sensu stricto, B. garinii, B. afzelii, B. valaisiana, and B. lusitaniae. Pathogenicity for humans remains uncertain for B. valaisiana and B. lusitaniae (4).
Neuroborreliosis, the most serious manifestation of disseminated Lyme disease, has become the most frequently recognized arthropodborne infection of the nervous system in the United States and Europe. B. garinii, B. afzelii, and B. burgdorferi sensu stricto are confirmed causes of neuroborreliosis (5); however, B. valaisiana has not been isolated from cerebrspinal fluid (CSF) until this report.
We report the genetic detection of B. valaisiana in the CSF of a 61-year-old man with a history of spastic paraparesis, which is strong clinical evidence of advanced neuroborreliosis. Symptoms, mainly difficulty in walking, began approximately 10 years earlier, with a slow progressive course of neuroborreliosis. His medical history showed an unidentified sexually transmitted disease in 1982, an undefined episode of arthritis in the lower limbs in 1990, and a nonspecific rash in the genitals in 1995. The patient lived in South Africa from 1961 to 1997 and visited Thassos Island in northern Greece every year. The neurologic examination demonstrated an intense pyramidal spasticity in the lower limbs and moderate weakness (Medical Research Council grade 3) of the proximal muscles. Serial magnetic resonance imaging (MRI) of the brain showed small hyperintensities in the periventricular area on T2-weighted images; MRI of the spinal cord showed no abnormalities. Multiple sclerosis, B12 deficiency, human T-cell lymphotrophic virus-1 infection, structural inflammatory lesions of the spinal cord, motor neuron disease, and hereditary spastic paraplegia have been excluded. The patient was treated occasionally with intravenous penicillin G, as well as with corticosteroids, but no clinical improvement was achieved. Venereal disease reaction level was negative and all tests for syphilis in CSF were negative.
DNA was extracted from CSF, and a region of the chromosomal flagellin gene of B. burgdorferi was amplified by nested PCR (3). B. afzelii (VS461) DNA was used as a positive control. All precautions were taken to avoid contamination. The amplified PCR product was sequenced, and the sequence (Th1) was deposited in GenBank with the accession no. AY270021. Phylogenetic analysis showed that strain Th1 was clustering with strains belonging to B. valaisiana genomic group. Specifically, a nucleotide difference of 0.38% was observed among Th1 and isolates Ku10 and To76 (accession no. AYO83505 and AYO83504, respectively), which belong to B. valaisiana genomic group and were isolated from ricinus in Sweden (6). A genetic difference of 0.77% was observed between Th1 and B. valaisiana strain Tr29 (accession no. ABO91805) isolated from I. ricinus in Turkey (7), while the genetic difference between Th1 and B. burgdorferi (X15661) was much greater, 6.83%.
This report is the first of genetic detection of B. valaisiana in CSF, which indicates a probable association of this genospecies with disease in humans. B. valaisiana has been isolated from I. ricinus ticks collected from vegetation and from ticks engorged on birds, in several European countries, including Turkey (7). The pathogenic capabilities of B. valasiana are still uncertain; it has been detected by PCR and restriction fragment length polymorphism analysis in skin biopsy specimens from two erythema migrans patients and from patients with mixed infection (erythema migrans and acrodermatitis chronica atrophicans) (4). Indirect evidence suggests that B. valaisiana is involved in some chronic clinical manifestations (8).
Borreliosis is difficult to diagnose by serologic evaluation and Western blot interpretation. In our patient, no intrathecal antibodies were produced to support clinical suspicion of disease. The low antibody titers could be attributed to antigenic variation between B. valaisiana and B. burgdorferi sensu stricto, which was used as antigen because no commercial kit is specific for B. valaisiana. Differences between the strain causing infection and the antigen may play a role in the false-negative results (9). The low antibody response in our patient could be caused by antimicrobial drugs and corticosteroid medication.
The high homology of the nucleotide sequence from our patient and respective B.valaisiana sequences from other European countries suggests that he likely was infected in Greece. The status of Lyme disease in southern Africa is unknown, but Ixodes spp. ticks have been found there, and preliminary evidence indicates that the disease may occur in humans in South Africa (10).
We detected B. valaisiana DNA in CSF of a patient with slow progressive spastic paraparesis, which suggests that this microorganism might be the causative agent of the disease. Nucleotide sequence information of Borrelia strains from clinical cases and ticks from different countries will elucidate the molecular epidemiology of the disease.

It is hoped this data will provide the reader with a broader understanding of neuroborreliosis so that he or she may better use current and evolving knowledge for clinical decision making.
I. NEUROBORRELIOSIS: MAKING THE DIAGNOSIS
Because of difficulties in making the diagnosis of neuroborreliosis, the physician will need a familiarity with the most common forms of presentations, which will be emphasized. The following points will help evaluate the patient for neuroborreliosis:
For most patients, systemic features of disease coexist with, or predate, neurologic manifestations.
Both central nervous and peripheral nervous system involvement is frequent with Lyme disease and typically occur together.
Laboratory data may or may not confirm the diagnosis, and other disease in the differential diagnosis must be evaluated thoroughly in cases where diagnostic ncertainty exists.
Although history of exposure to B. burgdorferi should be sought, for various reasons, patients may not remember a history of a tick bite, or the pathognomonic rash particularly if the disease is presenting years after the exposure.
Early on, personality changes, psychiatric symptoms, or cognitive manifestations may be the first, and occasionally the only, symptoms that the patient or family is aware of.
CLINICAL DESCRIPTIONS OF NEUROBORRELIOSIS
CENTRAL NERVOUS SYSTEM INVOLVEMENT
Meningismus with normal CSF
Subacute Encephalopathy (SAE)
PERIPHERAL NERVOUS SYSTEM INVOLVEMENT
CENTRAL NERVOUS SYSTEM
Patients may present with headache and stiff neck without evidence of CSF inflammation. Since early CNS seeding has been described, as well as culture positivity during latent disease without concurrent CNS inflammatory changes, these symptoms probably indicate active infection. Stiff neck might alternatively be due to axonal degenerative changes of the cervical paraspinal musculature, but there should be other evidence of a more widespread neuropathy when this is the case.
Lymphocytic Meningitis may appear to be indistinguishable from aseptic meningitis during early-disseminated disease (weeks to months after inoculation with B. burgdorferi). Most patients will have headaches that will fluctuate in intensity. Associated features may include a cranial neuropathy in about one-third. Low-grade encephalopathy is present in up to one-half, with mild memory concentration deficits, mood changes, and sleep disturbance.
Rarely, focal parenchymal CNS lesions occur. The MRI may show punctate white matter lesions best seen on T2-weighted images; larger lesions occur infrequently. One brain biopsy showed increased numbers of microglia cells, rare spirochetes, and minimal inflammation. Transverse myelitis, movement disorders (extrapyramidal cerebellar, chorea and myoclonus), and hemiparesis can occur.
Psychosis, mood swings (mild or bipolar), profound personality changes, depression, anorexia nervosa, obsessive-compulsive disorder, and panic attacks may occur. CSF may be normal.
SUBACUTE ENCEPHALOPATHY (SAE)
The most common chronic CNS manifestation is a SAE, characterized by memory problems and depression. Many patients (or their families) will complain of their excessive daytime sleepiness and extreme irritability. These patients generally come to the office disorganized (despite a supreme effort to be organized), unable to give a coherent history. They will bring copious notes, which are invariably in the wrong order. Most patients will complain of fatigue, and about one-half have headaches. Coincident polyneuropathy is very common with spinal or radicular pain, or distal paresthesias. Quantifiable deficits in memory, learning and retrieval, attention and concentration, perceptual-motor skills, and problem solving are common. MMPI testing generally shows a stable psychological pattern without significant psychopathology, similar to other medically ill patients.
ADDITIONAL CNS TESTING:
NEGATIVE TEST RESULTS DO NOT RULE OUT THE DIAGNOSIS OF NEUROBORRELIOSIS
Confirmation by CSF CULTURE is seldom practical because the organism is very fastidious, present in small numbers, takes a long time to grow out, and may undergo changes to forms which cannot be cultured easily.
CSF ANTIBODY TITERS may be present but are inconsistent and therefore their absence does not rule out CNS infection. The MRI is seldom abnormal and the findings, when present, are not specific for Lyme.
CSF PCR (test for spirochetal DNA) is a useful tool, but at present, because the capture of DNA is inconsistent, a few questions still need to be addressed.
OLIGLOCLONAL BANDS AND IGG INDEX — Looking for evidence of an intrathecal immune response may be helpful, but it is not specific. As a rule, oligoclonal bands and an elevated IgG index are not present in North American Lyme disease and their presence should suggest other diseases.
THE PERIPHERAL NERVOUS SYSTEM
Cranial neuropathy, painful radiculitis, distal neuropathy, and plexopathy are seen and generally reflect different clinical presentations of mononeuritis multiplex (polyneuropathy). Bell’s Palsy occurs in almost 11% of all Lyme patients and is bilateral in up to 1/3. Therefore, a bilateral Bell’s Palsy is very suspicious for Lyme in an endemic area. Painful radiculitis or cranial neuropathy can be seen with meningitis but also with normal CSF due to axonal neuropathy. Myositis may occur with Lyme as well as polymyalgia rheumatica. Symptoms of chronic involvement of the peripheral nervous system in a series of patients with chronic neurologic manifestations of Lyme disease developed a median of 16 months after the onset of infection, while CNS involvement began a median of 26 months after the onset of disease.
PERIPHERAL NERVOUS SYSTEM TESTING
Electrophysiological testing may show evidence of a mild peripheral neuropathy. Axonal degeneration and perivascular inflammatory infiltrates are noted on pathological specimens.
THE MOST COMMON PRESENTATION IS SAE, POLYNEUROPATHY, AND ARTHRITIS
Most typically, patients present with SAE, most often combined with polyneuropathy. Brief episodes of arthritis, primarily involving the knees, generally predate the symptoms and may persist after onset of neurological abnormalities. The TRIAD OF SAE, POLYNEUROPATHY, AND ARTHRITIS IS HIGHLY SUSPICIOUS FOR NEUROBORRELIOSIS.
Since serologies may be contradictory or negative, the physician will have to settle for treating if clinical suspicion is strong enough and assess whether the patient has “possible” or “probable” neuroborreliosis. Vigilant attempts to rule out other disorders should be undertaken. Screening should be done for collagen vascular disease, other infections, cancer, metabolic or endocrinological disturbances, etc. when a definite diagnosis cannot be made.
II. CURRENT MEDICAL MYTHOLOGY
“YOU HAVE FIBROMYALGIA. YOU MIGHT HAVE HAD LYME DISEASE IN THE FIRST PLACE, AND EVEN IF YOU DID, YOU WERE GIVEN ENOUGH ANTIBIOTICS. RETREATMENT WILL NOT HELP.”
PERSISTENT INFECTION VERSUS POST-LYME SYNDROME
Many patients are sent home with antidepressants, muscle relaxers, but no antibiotics from doctors’ offices because they have symptoms of fibromyalgia. Pictures similar, or identical, to fibromyalgia may be part of the constellation of symptoms of Lyme; it may occur more rarely as an isolated symptom, or surface after what would otherwise be considered successful treatment.
Symptoms of fibromyalgia due to Lyme disease have not been cured with short-term oral or intravenous antibiotics, so some argue fibromyalgia is not due to active infection. I would question whether those particular antibiotic regimens were adequate to eliminate the infection, rather than assume the patient has developed “Post-Lyme Syndrome” (some yet to be defined immunologically triggered disorder).
THE SCOPE OF THE PROBLEM
Bujak et al. evaluated patients a mean of almost five years after treatment. 15% of these patients had symptoms of fatigue and arthralgia. Almost one-half met criteria for fibromyalgia or chronic fatigue syndrome. Fibromyalgia is thought to be a variant of the chronic fatigue syndrome. Of note, nearly all patients continued to complain of memory loss or concentration difficulties. One quarter had objective evidence of cognitive impairment, and 15% manifested depression.
SYMPTOMS OF FIBROMYALGIA AND CHRONIC FATIGUE SYNDROME IN LYME DISEASE MAY BE ATTENUATED FORMS OR CHRONIC MANIFESTATIONS OF THE FLU-LIKE SYMPTOMS ASSOCIATED WITH EARLY DISSEMINATION
All physicians experienced with treating Lyme disease have had patients who present with a recurrence of flu-like symptoms, months to years after they have completed the usual antibiotic course of therapy, oral or intravenous, and re-exposure had not occurred. These patients describe their flu-like symptoms as identical to their early-disseminated stage of Lyme disease. The flu-like symptoms may reoccur following what appears to be a trivial stressor, such as an uncomplicated viral URI. Patients may be able to “contain” their symptoms without specific antimicrobial therapy, but many will have to resume antibiotics. These patients complain of having to go to bed due to excessive fatigue or hypersomnolence. They cannot think straight, their muscles and joints ache, and they may have a low-grade fever. Do these symptoms sound like a “fibromyalgia-like syndrome” or “acute fatigue syndrome?” Prior medical experience suggests reactivation of infection. Despite what may appear to have been a previous “cure,” relapse of symptoms in this context would appear to be due to failure to eradicate the infection and with reactivation after a period of dormancy. Reoccurrence of symptoms due to immunologically triggered disease, INDEPENDENT of persistent infection seems unlikely. In reality, DISTINCTIONS BETWEEN FLU-LIKE SYNDROME, FIBROMYALGIA, AND CHRONIC FATIGUE BLUR. It seems more logical to postulate that fibromyalgia and chronic fatigue syndrome, when seen with Lyme disease, may be attenuated forms of chronic manifestations of earlier flu-like symptoms associated with early dissemination.
III. THE ASSOCIATION BETWEEN MULTIPLE SCLEROSIS AND LYME DISEASE: THREE DIFFERENT SCENARIOS
1) LYME CAN LOOK LIKE MS BUT SYMPTOMS AND PATHOLOGY RESIDE OUTSIDE THE CENTRAL NERVOUS SYSTEM
Lyme may present as a MS-like illness, but on many occasions the pathology is not actually in the CNS. Since chronic Lyme symptoms often are predominantly shifting, vague, behavioral-psychological, psychiatric, and, as mentioned, neurological, they are likely to conjure up the diagnosis of MS in patients and physician alike. However, the existence of pathology outside the CNS should rule out the diagnosis of MS. Some of the vague symptoms that can be mistaken for MS include those that are better attributed to peripheral nervous system damage, as part of the mononeuritis multiplex that may occur. This might cause numbness, tingling, facial weakness, diplopia, etc. The diagnosis of MS cannot be made in the absence of CNS symptoms and signs. MRI and CSF findings would also help support the diagnosis of MS. In addition, a significant CSF pleocytosis may occur with Lyme disease, which should not be present with MS.
2) OTHER LYME PATIENTS DO HAVE CNS LESIONS, BUT THESE ARE GENERALLY DISTINCTLY DIFFERENT, CLINICALLY, AND PATHOLOGICALLY FROM MS
Patients can have CNS lesions in the brain or spinal cord with Lyme disease. The European literature includes many more cases than the American for encephalomyelitis, strokes, etc. In those cases where there is focal involvement of the brain or spinal cord, it may be more difficult to distinguish neuroborreliosis from MS. Again, a brisk CSF pleocytosis would help diagnose Lyme and the specific aforementioned test for CNS Lyme antibodies. Simultaneous appearance of peripheral nervous system abnormalities or arthritis should suggest the diagnosis of Lyme.
3) ANOTHER GROUP OF PATIENTS HAS MULTIPLE SCLEROSIS AND LYME
There are some patients who have a clear-cut preexisting history of MS before the onset of Lyme disease. The Lyme appears to accelerate their clinical course. For others, it appears to be the initiating infection that triggers the MS. These patients are most likely genetically predisposed to MS and the Lyme bacteria exerts its major effect by “turning on” immunologically directed CNS injury. It is not uncommon to get a history of the onset of an exacerbation of MS related to infections, so Lyme exacerbating MS would be expected. HLA Class II molecules determine the intensity of the immune response to pathogenic foreign or self-antigens. With MS, the HLA-DR4 DQw8 haplotype has been associated with chronic progressive MS and the HLA-DR2 DQw6 haplotype has been associated with susceptibility to both chronic progressive and relapsing or remitting MS. It is possible that in genetically predisposed patients of certain HLA types that infection by Lyme bacteria would cause a high production of cytokines that would mediate the demyelination and destruction of oligodendrocytes.
Most recently, researchers are studying positive outcomes when antibiotics that are most useful in treating Lyme disease are used to treat “MS.”
IV. WHAT'S WRONG WITH “CURRENT GUIDELINES FOR TREATMENT” OF NEUROBORRELIOSIS?
First, read the fine print.
It is interesting to note that recommendations for treatment in the medical literature may carry provisos in small print that can easily be overlooked but are instrumental to understanding how important individualization of therapy is at the current time. For instance, in the past and in small print Dr. Alan Steere has written, “treatment failures have occurred in all these regimens, and retreatment may be necessary; the duration of therapy is based on clinical response, and the appropriate duration of therapy with late neurological abnormalities may be longer than two weeks.” A more recent article written by Rahn and Malawista states “these guidelines are to be modified by new findings. It should always be applied with close attention to the clinical course of individual patients.” Dr. Katzel surveyed several Lyme Borreliosis conferences, including international ones. He finds a trend towards the use of antibiotics for longer periods than previously described and lack of standardization of care worldwide. 50% of physicians responding considered using antibiotics for time periods greater than one year in symptomatic seropositive patients, with almost as many extending therapy up to one and a half years when necessary.
THE CASE FOR PERSISTENT INFECTION
Studies have shown that Lyme bacteria can be an intracellular pathogen and may evade the normal host immune response. The causative spirochete, B. burgdorferi, for instance, may persist within fibroblasts and survive at least 14 days of exposure to ceftriaxone. In addition, B. burgdorferi has been cultured from CSF more than a half year after a standard regimen of IV antibiotics, according to Preac-Mursic. Logigian and Steere looked at patients with chronic neuroborreliosis, evaluating them six months after two weeks of IV ceftriaxone. Over one-half of the patients had already been treated with therapy that was thought appropriate for their stage of illness, yet the illness progressed. The majority of patients studied had subacute encephalopathy and polyneuropathy. Most had persistent fatigue, and almost one-half had headaches. One-third of these patients had to stop working or had to go part-time, underscoring the disability that may be seen with Lyme disease on an individual and societal level. After therapy, two-thirds of patients improved markedly, but seldom completely. Twenty-two percent improved but then relapsed, and fifteen percent had no change in their condition.
This study suggests that additional antibiotics greatly helped the majority with neuroborreliosis but they were insufficient to cause long lasting remission in those patients who subsequently relapsed. Persistent residual or irreversible disease may explain the fifteen percent who had no change in their condition.
For those clinicians who have had extensive experience with chronic neuroborreliosis, more recent recommendations suggesting that a regime of only 20 to 28 days or even 6 weeks of intravenous antibiotics is sufficient for cure proved contrary to clinical experience. That brief dosing does not appear to prevent relapse or improve long-term outcome dramatically in many cases. Perhaps, as recent information has instructed, that is because the immune system does not begin to repair itself until the beginning of the fourth month of antibiotic treatment. A trial of prolonged use of oral antibiotics seems more reasonable in many cases, given these circumstances.
Antibiotics used for chronic neuroborreliosis should be able to penetrate the blood-brain barrier, express activity against intracellular organisms, and assure good intraphagocytic penetration. It is anticipated that the microbe during late disease has achieved maximal adaptation to its host environment. Also, because of the long generation time of the organism, lengthier therapy is warranted.
V. WE DON'T HAVE ALL THE ANSWERS BUT HERE’S WHAT IS RECOMMENDED
If a patient has meningitis or appears acutely ill, particularly with possible arrhythmia, admit him or her to the hospital for intravenous antibiotics and observation. Generally, however, in patients with stable late disease, oral antibiotics can be tried first. The majority of patients will have some improvement or gradual resolution of encephalopathic symptoms with a better energy level. After a six-week trial of appropriate antibiotics, the patient is re-evaluated. If there is no Herxheimer response or some clinical improvement during this interval, it is worrisome, and the physician needs to be concerned about: 1) misdiagnosis, 2) noncompliance, and/or 3) permanent end organ damage. These possibilities should be addressed with the patient before proceeding with intravenous antibiotics since they may not be maximally beneficial either
Over the long haul, whether intravenous antibiotics are used for two weeks or longer, with chronic refractory disease, ultimately other methods are necessary. A lengthier use of oral antibiotics seems more logical than intravenous antibiotics for some patients. Unfortunately, there are no current tests that adequately measure disease activity with neuroborreliosis in all patients.
We are sorely in need of a test similar to the CSF VDRL for syphilis that would give us a measure of disease activity. Culture negativity or disappearance of a specific immune response in the serum or CSF has not been useful at this time to establish cure. CSF antibodies may persist for years after otherwise successful treatment. Particularly in the CNS, judging response of therapy is problematic because pathological changes may incompletely or, at least, very slowly reverse. Any clinical improvement would be expected to occur in a delayed fashion after therapy is given. Likewise, one would expect neuropathy related to axonal degeneration to remit slowly and/or incompletely. Formal neuropsychiatric testing is of value in documenting pathology and following the patient. It also helps delineate what the patient can and cannot do. It also can help to define the disease for the patient, family, insurer, and the employer. The patient needs to be told that his or her symptoms should remit slowly and incompletely, when on antibiotic treatment. This is particularly important when the symptoms have been chronic.
VI. IN SUMMARY
The premise of this approach to diagnosing and treating neuroborreliosis needs to be reinforced.
There is no current laboratory test that makes or breaks the diagnosis of neuroborreliosis. It is a clinical diagnosis substantiated by laboratory data when possible. Fortunately, the majority of cases are fairly uniform in their lack of uniformity, and other diagnoses are easily ruled out. In situations where the physician simply cannot achieve diagnostic certainty, he or she should notify the patient that the diagnosis is “possible” or “probable” neuroborreliosis. This has been done previously with MS (i.e., possible, probable, and definite MS), another disease where laboratory testing does not make the diagnosis in and of itself.
There is no perfect current laboratory test to monitor success of therapy, and this is critically needed. Until better testing is available, assessing progress, or lack thereof, will largely be determined with clinical acumen.
The infection is difficult to eradicate and may require long-term treatment. The spirochete, particularly in later stages, becomes well adapted to survival within its host environment. There are some patients that we may not be able to cure, but will be able to palliate with currently available antibiotics.
Although immunopathogenic factors may play a crucial role in disease presentation, the presence of chronic infection appears necessary to perpetuate the process and play a causative role in persistence of immunologically triggered symptoms.
There is no Diagnostic and Statistic Psychiatry Manual (DSM IV) category for “antibiotic seeking behavior.” It is common for physicians who are unable to explain patients’ symptoms or effect their cure to ascribe a psychiatric cause to their malady. This is easily done with Lyme since objective findings may be subtle or non-existent. Because neuropsychiatric symptoms may pre-dominate, it is easy in some patients to attribute their symptoms to depression or secondary gain. These patients do not in any other way seek other medication that would be associated with habituation or addiction (i.e., pain medicine).
Many patients suffer unfairly at the hands of physicians who refuse to make the diagnosis because blood tests are either contradictory or negative. “Lyme bashing,” for instance, referring to Lyme disease as “yuppie flu,” is demeaning. The “just say no” attitude of certain physicians towards Lyme patients who request retreatment with antibiotics should not be condoned in the face of continuing experience with this potentially chronically disabling infectious disease.

Cytokines and chemokines at the crossroads of neuroinflammation, neurodegeneration, and neuropathic pain.

Cytokines and chemokines are proteins that coordinate the immune response throughout the body. The dysregulation of cytokines and chemokines is a central feature in the development of neuroinflammation, neurodegeneration, and demyelination both in the central and peripheral nervous systems and in conditions of neuropathic pain. Pathological states within the nervous system can lead to activation of microglia. The latter may mediate neuronal and glial cell injury and death through production of proinflammatory factors such as cytokines and chemokines. These then help to mobilize the adaptive immune response. Although inflammation may induce beneficial effects such as pathogen clearance and phagocytosis of apoptotic cells, uncontrolled inflammation can result in detrimental outcomes via the production of neurotoxic factors that exacerbate neurodegenerative pathology. In states of prolonged inflammation, continual activation and recruitment of effector cells can establish a feedback loop that perpetuates inflammation and ultimately results in neuronal injury. A critical balance between repair and proinflammatory factors determines the outcome of a neurodegenerative process. This review will focus on how cytokines and chemokines affect neuroinflammation and disease pathogenesis in bacterial meningitis and brain abscesses, Lyme neuroborreliosis, human immunodeficiency virus encephalitis, and neuropathic pain.

Lyme borreliosis is the most common tick-born infection in Europe. Global climate change expanding the range of tick vectors and an increase in the incidence suggest that this disease will remain an important health issue in the forthcoming decades. Lyme borreliosis is a multisystem organ disorder affecting the nervous system in 10% to 15% of cases. Lyme neuroborreliosis can present with any disorder of the central and peripheral nervous systems. The neuro-ophthalmological manifestations are a rare feature of the disease. The intrathecal synthesis of Borrelia burgdorferi antibodies is of diagnostic importance, but in rare cases, immunoglobulins against the Borrelia burgdorferi antigen may not be detected.
We report a case of possible Lyme neuroborreliosis presenting with sixth cranial nerve neuropathy at the onset of the disease further developing into typical meningoradiculitis and multiple mononeuropathy. Surprisingly, Borrelia burgdorferi antibodies were not detected in the cerebrospinal fluid.

INTRODUCTION: Neuroborreliosis can be a difficult diagnosis which requires
epidemiologic, clinical and biologic arguments. CASE REPORTS: We report two
patients who presented with a recurrent laryngeal nerve palsy with positive Lyme
serology and favorable outcome after antibiotic therapy. In one case, a
lymphocytic meningitis with intrathecal production of specific antibodies was
evidenced. CONCLUSION: Recurrent laryngeal nerve palsy is an uncommon
manifestation of neuroborreliosis. Lyme serology is an important tool when
neurologic disorder occurs because of an atypical course of Lyme disease.

Lyme disease (borreliosis) is a systemic illness resulting from infection with
the spirochete Borrelia burgdorferi. It is transmitted to humans by the bites of
infected ticks belonging to several species of the genus Ixodes. After the
bacteria enter the body via the dermis, most patients develop the early,
localised form of Lyme disease, which is characterised by erythema migrans and
influenza-like symptoms. This disease may also affect the heart, nervous system
and joints. The neurological findings of this disease may include peripheral and
central nervous system signs.
A 21-year-old woman attended a family medicine
outpatient clinic complaining of unexplained pain and muscle power loss in her
lower extremities. The problem had started in her right leg 3 months earlier and
worsened in the last week. She had a neurology consultation and was
hospitalised. Her neurological examination revealed bilateral facial paralysis
and sensory impairment. Immunoglobulin M antibody to B. burgdorferi was positive
on Western blotting in both serum and cerebrospinal fluid. The patient was
diagnosed with subacute neuroborreliosis and treated.

Neuroinflammation in Lyme neuroborreliosis affects amyloid metabolism
Niklas Mattsson*, Daniel Bremell, Rolf Anckarsäter, Kaj Blennow, Henrik Anckarsäter, Henrik Zetterberg,and Lars Hagberg
The metabolism of amyloid precursor protein (APP) an
d β-amyloid (Aβ) is widely studied in Alzheimer's
disease, where Aβ deposition and plaque development are
essential components of the pathogenesis. However, the
physiological role of amyloid in the adult nervous system remains largely unknown. We have previously found altered
cerebral amyloid metabolism in other neuroinflammatory conditions. To further elucidate this, we investigated amyloid
metabolism in patients with Lyme neuroborreliosis (LNB).
The first part of the study was a cro
ss-sectional cohort study in
61 patients with acute facial palsy (19 with
LNB and 42 with idiopathic facial pare
sis, Bell's palsy) and 22 healthy controls. CSF was analysed for the β-amyloid
peptides Aβ38, Aβ40 and Aβ42, and the amyloid precursor pr
otein (APP) isoforms α-sAPP and β-sAPP. CSF total-tau (T-
tau), phosphorylated tau (P-tau) and neurofilament protein
(NFL) were measured to moni
tor neural cell damage. The
second part of the study was a prospective cohort-study in
26 LNB patients undergoing consecutive lumbar punctures
before and after antibiotic treatment to study time-dependent dynamics of the biomarkers.
In the cross-sectional st
udy, LNB patients had lower levels of CSF α-sAPP, β-sAPP and P-tau, and higher levels of
CSF NFL than healthy controls and patients with Bell's palsy.
In the prospective study, LNB patients had low levels of
CSF α-sAPP, β-sAPP and P-tau at baseline, whic
h all increased towards normal at follow-up.
Amyloid metabolism is altered in LNB. CSF levels
of α-sAPP, β-sAPP and P-tau are decreased in acute
infection and increase after treatment. In combination with ea
rlier findings in multiple sc
lerosis, cerebral SLE and HIV
with cerebral engagement, this points to an infl
uence of neuroinflammation on amyloid metabolism.
The trans-membranous protein amyloid precursor pro-
tein (APP) has been intensely studied in Alzheimer's dis-
ease (AD), since it is the source of β-amyloid (Aβ)
peptides, recognized as key-components in AD
pathophysiology . Although ubiquitously expressed,
the physiological role of APP in the adult organism
remains largely unknown. APP may undergo non-amy-
loidogenic cleavage at the α-site, which inhibits formation
of Aβ and releases an extracellular soluble α-sAPP frag-
ment. Alternatively, APP is processed by combined cleav-
ages by β-secretase and γ-secretase, releasing Aβ and β-
sAPP. Aβ peptides vary in length due to variability in the
γ-secretase cleavage site. Although CSF levels of α-sAPP
and β-sAPP generally correlate tightly , it is not known
how these pathways are orchestrated
. CSF levels of
α-sAPP and β-sAPP are reduced in MS and cerebral sys-
temic lupus erythematosus SLE , and even lower levels
are seen in HIV patients with cerebral engagement .
Lyme neuroborreliosis (LNB) is caused by a central ner-
vous system (CNS) infection by the tick-borne spirochete
. LNB is often manifested by cranial
nerve engagement, and common clinical findings are
facial nerve palsy and radiculitic pain [5,6]. Common lab-
oratory findings are increased albumin ratio, indicating
impaired blood-brain barrier function, and CSF monocy-
tosis. In this study, we investigated CSF markers of amy-
loid metabolism and neural cell damage in LNB, to
elucidate the influence of neuroinflammation on amyloid

The project contained two clinical studies. The first
was a cross-sectional study in patients with acute facial
palsy caused by either LNB or idiopathic Bell's palsy. The
second was a longitudinal prospective cohort-study,
where LNB patients were followed with successive lum-
bar punctures to investigate time-dependent biomarker
We enrolled different study participants for the cross-
sectional study and the longitudinal study. Participants
included LNB patients, Bell's palsy patients and controls.
Diagnostic criteria for LNB were: I. Clinical symptoms
consistent with neuroborreliosis and alternative explana-
tions excluded; II Inflammatory CSF with mononuclear
cell count >5 × 10
/l and erythrocytes <100 × 10
One or more of the following: a) Intrathecal antibody
B burgdorferi sp
. b) Antibodies against
B burgdorferi sp
. in serum. c) Erythema migrans within
three months; and IV. One or more of the following: a)
CSF albumin >400 mg/L. b) Oligoclonal IgG and/or IgM-
synthesis on CSF protein electrophoresis. c) IgG index
(CSF/serum IgG ratio)/(CSF/serum albumin ratio) > .70.
Bell's palsy (idiopathic facial palsy) was defined as acute,
monosymptomatic, unilateral peripheral facial paresis of
unknown etiology. Bell's palsy patients were included as
non-infectious palsy controls.
In the cross-sectional part of the study we investigated
61 patients of whom 19 fulfilled criteria for LNB and 42
were classified as Bell's palsy. Twenty-two individuals for
whom CSF analysis was done because of headache or ver-
tigo, but infection and other diseases were excluded (CSF
albumin and cell count were normal), served as controls.
The longitudinal study included 26 LNB patients with
radiculitic pain and sensory disturbances. In addition, 3
patients had facial palsy, 3 had paraparesis, 1 had paresis
of the accessorius nerve, and 1 had a trigeminus paresis.
There was no overlap with the patients in the cross-sec-
tional study. Ten patients without any neurological disor-
ders, undergoing knee replacements, where CSF was
drawn before surgery (Table 1) served as controls in the
longitudinal study. These subjects are described in detail
elsewhere . All LNB patients were given oral treatment
with doxycycline 200-400 mg daily for 10-14 days, which
is the standard treatment in Sweden . CSF was drawn
before start of treatment and at follow-up. The median
duration between the samplings was 45 days (range 33-
61). All subjects gave informed consent to participate.
The study was approved by the ethics committee of Uni-
versity of Gothenburg.
CSF samples were collected by lumbar puncture in the
L3/L4 or L4/L5 interspace. Four mL of CSF was collected
in a polypropylene tube and immediately transported to
the local laboratory for centrifugation at 2.000 g at +4°C
for 10 minutes. The supernatant was pipetted off, gently
mixed to avoid possible gradient effects, and aliquoted in
polypropylene tubes that were stored at -70°C pending
biochemical analyses, without being thawed and re-fro-
All biochemical analyses were performed at the Clinical
Neurochemistry Laboratory in Mölndal, Sweden, by
experienced laboratory technicians who were blinded to
the clinical diagnoses and other clinical information.
Markers of amyloid metabolism
CSF levels of Aβ38, Aβ40 and Aβ42 were measured using
Human/Rodent (4G8) Abeta Triplex Assay as
described by the manufacturer (Meso Scale Discovery,
, Gaithersburg, MD, USA). This assay employs the
4G8 antibody to capture Aβ and C-terminal specific anti-
bodies to specifically capture Aβ38, Aβ40 and Aβ42. All
isoforms are detected by SULFO-TAG™-labeled anti-4G8
detection antibody. CSF concentrations of α-sAPP and β-
sAPP were determined using the MSD
Multiplex Assay as described by the manufacturer. This
assay employs the 6E10 antibody to capture α-sAPP and a
neoepitope-specific antibody to capture β-sAPP. Both
isoforms are detected by SULFO-TAG™-labeled anti-APP
Markers of neural cell damage
The axonal damage marker CSF T-tau was measured
using a sandwich ELISA (INNOTEST
netics, Ghent, Belgium) specifically constructed to mea-
sure all tau isoforms irrespectively of phosphorylation
status (T-tau), as previously described . CSF concen-
trations of tau phosphorylated at threonine 181 (P-tau)
was measured using a sandwich ELISA (INNOTEST
PHOSPHO-TAU(181P), Innogenetics), as previously
described . CSF NFL, which is increased following
damage to large myelinated axon, was analyzed using an
ELISA, as previously described . The detection limit
for the NFL ELISA was 125 ng/L.
Quantitative determination of albumin in serum and CSF
was performed using the Behring Nephelometer Analyser
(Behringwerke AG, Marburg, Germany). The CSF/serum
albumin ratio was calculated as: CSF albumin (mg/l)/
All statistical calculations were performed using SPSS
15.0 (SPSS Inc, Chicago, USA). As the distribution of
quantitative measures was significantly skewed, statistical
tests involving these variables were conducted using the
Page 3 of 7
non-parametric Kuskal-Wallis test for comparisons of
multiple groups and the Mann-Whitney U test for pair-
wise comparisons between groups. Quantitative variables
are presented as median (range). The Spearman correla-
tion coefficient was used for analyses of correlation
between variable levels in different study groups. Statisti-
cal significance was determined at P < .05.
Role of the funding source
The sponsors of the study had no role in study design,
data collection, data analysis, data interpretation, or writ-
ing of the report. The corresponding author had full
access to all the data in the study and had final responsi-
bility for the decision to submit for publication.
In the cross-sectional study all groups were comparable
in age. The only exception was that Bell's palsy patients
were slightly younger than th
e controls (P = .023, Table
1). LNB patients had longer history of neurological symp-
toms before the time of lumbar puncture than Bell's palsy
patients (Table 1).
In the longitudinal study, LNB patients were younger
than the controls (P = .031, Table 1). The median dura-
tion of neurologic symptoms was 7 days longer than in
the cross-sectional study (21 days compared with 28
days). At follow-up, all LNB patients had improved in
their clinical symptoms and their inflammatory reactions
had diminished, with decreased CSF monocytic cell
counts (Table 1).
In the cross-sectional study, LNB patients had lower α-
sAPP and β-sAPP than the other groups (Figure 1), but
there were no differences in Aβ38, Aβ40 or Aβ42 (Table
2). α-sAPP and β-sAPP correlated to most Aβ peptides in
Bell's palsy patients (R = .47-.60, P ≤ .002) and controls (R
= .42-.55, P < .05; the only exception was α-sAPP and
Aβ38 in controls, where there was a trend towards signif-
icance, R = .40, P = .065), but not in LNB patients (P >
In the longitudinal study, LNB patients had lower base-
line levels of α-sAPP and β-sAPP (Figure 2) and Aβ pep-
tides than controls (Table 3). α-sAPP and β-sAPP
increased after treatment (Figure 2), while Aβ levels were
unaffected (Table 3). Conversely to what was seen in the
cross-sectional study, α-sAPP and β-sAPP correlated to
all Aβ peptides in LNB in the longitudinal study (R = .71-
.98, P < .001), but not in controls (P > .05).

It is established that chronic spirochetal infection can cause slowly progressive dementia, brain atrophy and amyloid deposition in late neurosyphilis. Recently it has been suggested that various types of spirochetes, in an analogous way to Treponema pallidum, could cause dementia and may be involved in the pathogenesis of Alzheimer's disease (AD). Here, we review all data available in the literature on the detection of spirochetes in AD and critically analyze the association and causal relationship between spirochetes and AD following established criteria of Koch and Hill. The results show a statistically significant association between spirochetes and AD (P = 1.5 × 10-17, OR = 20, 95% CI = 8-60, N = 247). When neutral techniques recognizing all types of spirochetes were used, or the highly prevalent periodontal pathogen Treponemas were analyzed, spirochetes were observed in the brain in more than 90% of AD cases.
Borrelia burgdorferi was detected in the brain in 25.3% of AD cases analyzed and was 13 times more frequent in AD compared to controls. Periodontal pathogen Treponemas (T. pectinovorum, T. amylovorum, T. lecithinolyticum, T. maltophilum, T. medium, T. socranskii) and Borrelia burgdorferi were detected using species specific PCR and antibodies. Importantly, co-infection with several spirochetes occurs in AD. The pathological and biological hallmarks of AD were reproduced in vitro by exposure of mammalian cells to spirochetes. The analysis of reviewed data following Koch's and Hill's postulates shows a probable causal relationship between neurospirochetosis and AD. Persisting inflammation and amyloid deposition initiated and sustained by chronic spirochetal infection form together with the various hypotheses suggested to play a role in the pathogenesis of AD a comprehensive entity. As suggested by Hill, once the probability of a causal relationship is established prompt action is needed. Support and attention should be given to this field of AD research.
Spirochetal infection occurs years or decades before the manifestation of dementia. As adequate antibiotic and anti-inflammatory therapies are available, as in syphilis, one might prevent and eradicate dementia.

The recognition that pathogens can produce slowly progressive chronic diseases has resulted in a new concept of infectious diseases. The pioneering work of Marshall and Warren has established that Helicobacter pylori (H. pylori) causes stomach ulcer . Also the etiologic agent of Whipple's disease was revealed to be another bacterium, Tropheryma whippeli. Recent reports have documented that infectious agents also occur in atherosclerosis, cardio- and cerebrovascular disorders [2-10], diabetes mellitus [11-16], chronic lung [17-20] and inflammatory bowel diseases[1,21-25], and various neurological and neuropsychiatric disorders [26-31].
Nearly a century ago, Fischer, Alzheimer and their colleagues [32,33] discussed the possibility that microorganisms may play a role in the formation of senile plaques. Historic data indicate that the clinical and pathological hallmarks of syphilitic dementia in the atrophic form of general paresis, caused by chronic spirochetal infection, are similar to those of AD. There is an increasing amount of data that indicates that spirochetes are involved in the pathogenesis of AD. This review presents historic and new data related to the involvement of spirochetes in AD. The goal was to critically analyze the association and causality between spirochetes and AD, based on the substantial amount of data available and on established criteria of Koch [34,35] and Hill

Role of Chronic Bacterial and Viral Infections in Neurodegenerative, Neurobehavioral, Psychiatric, Autoimmune and Fatiguing Illnesses: Part 1

Chronically ill patients with neurodegenerative, neurobehavioral and psychiatric diseases commonly have systemic and central nervous system bacterial and viral infections. In addition, other chronic illnesses where neurological manifestations are routinely found, such as fatiguing and autoimmune diseases, Lyme disease and Gulf War illnesses, also show systemic bacterial and viral infections that could be important in disease inception and progression or in increasing the number and severity of signs and symptoms. Evidence of Mycoplasma species, Chlamydia pneumoniae, Borrelia burgdorferi, human herpesvirus-1, -6 and -7 and other bacterial and viral infections revealed high infection rates in the above illnesses that were not found in controls. Although the specific roles of chronic infections in various diseases and their pathogeneses have not been carefully determined, the data suggest that chronic bacterial and/or viral infections are common features of progressive chronic diseases.

Chronic infections appear to be common features of various diseases, including neurodegenerative, psychiatric and neurobehavioral diseases, autoimmune diseases, fatiguing illnesses and other conditions.1-4 Neurodegenerative diseases, chronic degenerative diseases of the central nervous system (CNS) that cause dementia, are mainly diseases of the elderly. In contrast, neurobehavioral diseases are found mainly in younger patients and include autism spectrum disorders (ASD), such as autism, attention deficit disorder, Asperger’s syndrome and other disorders.5 For the most part, the causes of these neurological diseases remain largely unknown.2 Neurodegenerative diseases are characterized by molecular and genetic changes in nerve cells that result in nerve cell degeneration and ultimately nerve cell dysfunction and death, resulting in neurological signs and symptoms and dementia.2,3 On the other hand, neurobehavioral diseases are related to fetal brain development but are less well characterized at the cellular level and involve both genetic and environmental factors.6, 7 Even less well characterized at the cellular and genetic level are the psychiatric disorders, such as schizophrenia, paranoia, bipolar disorders, depression and obsessive-compulsive disorders.
Genetic linkages have been found in neurodegenerative and neurobehavioral diseases, but the genetic changes that occur and the changes in gene expression that have been found are complex and usually not directly related to simple genetic alterations.2, 6-8 In addition, it is thought that nutritional deficiencies, environmental toxins, heavy metals, chronic bacterial and viral infections, autoimmune immunological responses, vascular diseases, head trauma and accumulation of fluid in the brain, changes in neurotransmitter concentrations, among others, are involved in the pathogenesis of various neurodegenerative and neurobehavioral diseases.2, 3, 5-16 One of the biochemical changes found in essentially all neurological, neurodegenerative and neurobehavioral diseases is the over-expression of oxidative free radical compounds (oxidative stress) that cause lipid, protein and genetic structural changes.9-11 Such oxidative stress can be caused by a variety of environmental toxic insults, and when combined with genetic factors could result in pathogenic changes.14
Infectious agents are important factors in neurodegenerative and neurobehavioral diseases and may enter the brain within infected migratory macrophages. They may also gain access by transcytosis across the blood-brain-barrier or enter by intraneuronal transfer from peripheral nerves.15 Cell wall-deficient bacteria, such as species of Mycoplasma, Chlamydia (Chlamydophila), Borrelia and Brucella, among others, and various viruses are candidate brain infectious agents that may play important roles in neurodegenerative and neurobehavioral diseases.16-19 Such infections are systemic and can affect the immune system and essentially any organ system, resulting in a variety of systemic signs and symptoms.4, 15, 16, 19, 20
Amyotrophic lateral sclerosis
Amyotrophic lateral sclerosis (ALS) is an adult-onset, idiopathic, progressive neurodegenerative disease that affects both central and peripheral motor neurons.21 Patients show gradual progressive weakness and paralysis of muscles due to destruction of upper motor neurons in the motor cortex and lower motor neurons in the brain stem and spinal cord. This ultimately results in death, usually by respiratory failure.21, 22 The overall clinical picture of ALS can vary, depending on the location and progression of pathological changes.23
The role of chronic infections has attracted attention with the finding of enterovirus sequences in a majority of ALS spinal cord samples by polymerase chain reaction (PCR).24 However, others have failed to detect enterovirus sequences in spinal cord samples from patients with or without ALS.25-26 In spite of the mixed findings on enterovirus, infectious agents that penetrate the CNS could play a role in the aetiology of ALS. Evidence for transmission of an infectious agent or transfer of an ALS-like disease from man-to-man or man-to-animals has not been found.27
Using PCR methods systemic mycoplasmal infections have been found in a high percentage of ALS patients.28, 29 We found that 100% of Gulf War veterans from three nations diagnosed with ALS had systemic mycoplasmal infections.28 All but one patient had M. fermentans, and one veteran from Australia had a systemic M. genitalium infection. In nonmilitary ALS patients systemic mycoplasmal infections of various species were found in approximately 80% of cases.28 Of the mycoplasma-positive civilian patients who were further tested for various species of Mycoplasma, most were positive for M. fermentans (59%), but other Mycoplasma species, such as M. hominis (31%) and M. pneumoniae infections (9%) were also present. Some of the ALS patients had multiple infections; however, multiple mycoplasmal infections were not found in the military patients with ALS.28 In another study 50% of ALS patients showed evidence of systemic Mycoplasma species by PCR analysis.29
ALS patients who live in certain areas often have infections of Borrelia burgdorferi, the principal aetiological agent in Lyme disease. For example, ALS patients who live in a Lyme-prevalent area were examined for B. burgdorferi infections, and over one-half were found to be seropositive for Borrelia compared to 10% of matched controls.30 In addition, some patients diagnosed with ALS were subsequently diagnosed with neuroborreliosis.31 Spirochetal forms have been observed in the brain tissue of ALS patients and in patients with other neurodegenerative diseases.32 In general, however, the incidence of Lyme infections in ALS patients is probably much lower. In one recent study on 414 ALS patients only about 6% showed serological evidence of Borrelia infections.33 Some Lyme Disease patients may progress to ALS, but this is probably only possible in patients who have the genetic susceptibility genes for ALS as well as other environmental toxic exposures.34, 35
Additional chronic infections have been found in ALS patients, including human herpes virus-6 (HHV-6), Chlamydia pneumoniae andother infections.36, 37 There is also a suggestion that retroviruses might be involved in ALS and other motorneuron diseases.38 McCormick et al.39 looked for reverse transcriptase activity in serum and cerebrospinal fluid of ALS and non-ALS patients and found reverse transcriptase activity in one-half of ALS serum samples tested but in only 7% of controls. Interestingly, only 4% of ALS cerebrospinal fluid samples contained reverse transcriptase activity.39
Although the exact cause of ALS remains to be determined, there are several hypotheses on its pathogenesis: (1) accumulation of glutamate causing excitotoxicity; (2) autoimmune reactions against motor neurons; (3) deficiency of nerve growth factor; (4) dysfunction of superoxide dismutase due to mutations; and (5) chronic infection(s).24, 27-40 None of these hypotheses have been ruled out or are exclusive, and ALS may have a complex pathogenesis involving multiple factors. 28, 36
It is tempting to propose that infections play an important role in the pathogenesis or progression of ALS.28, 40 Infections could be cofactors in ALS pathogenesis, or they could simply be opportunistic, causing morbidity in ALS patients. For example, infections could cause the respiratory and rheumatic symptoms and other problems that are often found in ALS patients. Since the patients with multiple infections were usually those with more rapidly progressive disease,28 infections likely promote disease progression. Indeed, when Corcia et al.41 examined the cause of death in 100 ALS patients, the main causes were broncho-pneumonia and pneumonia. Finally, there are a number of patients who have ALS-like signs and symptoms but fall short of diagnostic criteria. Although a careful study has not been attempted on these patients, there is an indication that they have the same infections as those found in patients with a full diagnosis of ALS (personal communication). Thus ALS-like diseases may represent a less progressive state, in that they may lack additional changes or exposures necessary for full ALS.
Multiple sclerosis (MS) is the most common demyelinating neurological disease. It can occur in young or older people and is a cyclic (relapsing-remitting) or progressive disease that continues progressing without remitting.42 Inflammation and the presence of autoimmune antibodies against myelin and other nerve cell antigens are thought to cause the myelin sheath to break down, resulting in decrease or loss of electrical impulses along the nerve fibers.42, 43 In the progressive subset of MS neurological damage occurs additionally by the deposition of plaques on the nerve cells to the point where nerve cell death occurs. In addition, breakdown of the blood-brain barrier in MS is associated with local inflammation caused by glial cells.42, 43 The clinical manifestations of demyelinization, plaque damage and blood-brain barrier disruptions cause variable symptoms, but they usually include impaired vision, alterations in motor, sensory and coordination systems and cognitive dysfunction.43
There is strong evidence for a genetic component in MS.44, 45 Although it has been established that there is a genetic susceptibility component to MS, epidemiological and twin studies suggest that MS is an acquired, rather than an inherited, disease.46
MS has been linked to chronic infection(s).46, 47 For example, patients show immunological and cytokine elevations consistent with chronic infections.48-50 An infectious cause for MS has been under examination for some time, and patients have been tested for various viral and bacterial infections. 44, 45,47, 48, 51 One of the most common findings in MS patients is the presence of C. pneumoniae antibodies and DNAin their cerebrospinal fluid.51-53 By examining relapsing-remitting and progressive MS patients for the presence of C. pneumoniae in cerebrospinal fluid by culture, PCR and immunoglobulin reactivity Sriram et al.52 were able to identify C. pneumoniae in 64% of MS cerebrospinal fluid versus 11% of patients with other neurological diseases. They also found high rates (97% positive) of PCR-positive MOMP gene in MS- patients versus 18% in other neurological diseases, and this correlated with 86% of MS patients being serology-positive patients by ELISA and Western blot analysis.52 Examination of MS patients for oligoclonal antibodies against C. pneumoniae revealed that 82% of MS patients were positive, whereas none of the control non-MS neurological patients had antibodies that were absorbed by C. pneumoniae elemental body antigens.53 Similarly, Contini et al.54 found that the DNA and RNA transcript levels in mononuclear cells and cerebrospinal fluid of 64.2% of MS patients but in only 3 controls.
Using immunohistochemistry Sriram et al.55 later examined formalin-fixed brain tissue from MS and non-MS neurological disease controls and found that in a subset of MS patients (35%) chlamydial antigens were localized to ependymal surfaces and periventricular regions. Staining was not found in brain tissue samples from other neurological diseases. Frozen tissues were available in some of these MS cases, and PCR amplification of C. pneumoniae genes was accomplished in 63% of brain tissue samples from MS patients but none in frozen brain tissues from other neurological diseases. In addition, using immuno-gold-labeled staining and electron microscopy they examined cerebrospinal fluid sediment for chlamydial antigens and found that the electron dense bodies resembling bacterial structures correlated with PCR-positive results in 91% of MS cases.55 They also used different nested PCR methods to examine additional C. pneumoniae gene sequences in the cerebrospinal fluid of 72 MS patients and linked these results to MS-associated lesions seen by MRI.56
MRI was used by Grimaldi et al.57 to link the presence of C. pneumoniae infection with abnormal MRI results and found linkage in 21% of MS patients. These turned out to be MS patients with more progressive disease.58 In addition, higher rates of C. pneumoniae transcription were found by Dong-Si et al.58 in the cerebrospinal fluid of 84 MS patients. The data above and other studies strongly support the presence of C. pneumoniae in the brains of MS patients,59-61 at least in the more progressed subset of MS patients.
Other research groups have also found evidence for C. pneumoniae in MS patients but at lower incidence. Fainardi et al.62 used ELISA techniques and found that high-affinity antibodies against C. pneumoniae were present in the cerebrospinal fluid of 17% of MS cases compared to 2% of patients with non-inflammatory neurological disorders. They found that the majority of the progressive forms of MS were positive compared to patients with remitting-relapsing MS. The presence of C. pneumoniae antibodies was also found in other inflammatory neurological disorders; thus it was not found to be specific for MS.62
In contrast to the studies above, other researchers have not found the presence of C. pneumoniaeor other bacteriain the brains of MS patients.63-65 For example, Hammerschlag et al.66 used nested PCR and culture to examine frozen brain samples from MS patients but could not find any evidence for C. pneumoniae. However, in one study C. pneumoniae was found at similar incidence in MS and other neurological diseases, but only MS patients had C. pneumoniae in their cerebrospinal fluid.64 Swanborg et al.67 reviewed the evidence linking C. pneumoniae infection with MS and concluded that it is equivocal, and they also speculated that specific genetic changes may be necessary to fulfill the role of such infections in the aetiology of MS.
Another possible reason for the equivocal evidence linking MS with infections, such as C. pneumoniae, is that multiple co-infections could be involved rather than one specific infection. In addition to C. pneumoniae found in most studies, MS patients could also have Mycoplasma species, B. burgdorferi and other bacterial infections as well as viral infections.68 When multiple infections are considered, it is likely that >90% of MS patients have obligate intracellular bacterial infections caused by Chlamydia (Chlamydophila), Mycoplasma, Borrelia or other intracellular bacterial infections. These infections were found only singly and at very low incidence in age-matched subjects.68 In spite of these findings, others did not find evidence of Mycoplasma species in MS brain tissue, cerebrospinal fluid or peripheral blood.69
Viruses have also been found in MS. For example, HHV-6 has been found at higher frequencies in MS patients, but this virus has also been found at lower incidence in control samples.70 Using PCR Sanders et al.70 examined postmortem brain tissue and controls for the presence of various neurotrophic viruses. They found that 57% of MS cases and 43% of non-MS neurological disease controls were positive for HHV-6, whereas 37% and 28%, respectively, were positive for herpes simplex virus (HSV-1 and -2) and 43% and 32%, respectively, were positive for varicella zoster virus. However, these differences did not achieve statistical significance, and the authors concluded “an etiologic association to the MS disease process [is] uncertain.” They also found that 32% of the MS active plaques and 17% of the inactive plaque areas were positive for HHV-6.70 Using sequence difference analysis and PCR Challoner et al.71 searched for pathogens in MS brain specimens. They found that >70% of the MS specimens were positive for infection-associated sequences. They also used immunocytochemistry and found staining around MS plaques more frequently than around white matter. Nuclear staining of oligodendrocytes was also seen in MS samples but not in controls.71 Using immunofluorescent and PCR methods HHV-6 DNA has also been found in peripheral leukocytes in the systemic circulation of MS patients.72, 73 However, using PCR methods, others did not found herpes viruses in the peripheral blood or CSF of MS patients.74, 75 Evidence that prior infection with EBV could be related to the development of MS was proposed; however, EBV infects more than 90% of humans without evidence of health problems and 99% of MS patients.76 The difference in MS patients could be the presence of multiple infections, including EBV. Recently Willis et al.77 used multiple molecular techniques to examine MS tissue but failed to find EBV in any MS tissues but could find EBV in CNS lymphomas.
Current reviews and the information above points to an infectious process in MS.47, 48, 75, 76, 78-80 Although a few studies did not come to this conclusion,74, 75 most studies have found infections in MS patients. It is interesting that it is the progressive rather than relapsing-remitting forms of MS which have been associated with chronic infections; therefore, infections might be more important in MS progression than in its inception. Various infections may also nonspecifically stimulate the immune system.47, 48 Infections may also invade immune cells and alter immune cell function in a way that promotes inflammation and autoimmune activity.78 If infections like C. pneumoniae and Mycoplasma species are important in MS, then antibiotics effective against these infections should improve clinical status. Although preliminary, that is in fact what has been seen, but not in all patients.81 As in other neurodegenerative diseases, multiple factors appear to be involved in the pathogenesis of MS.
Alzheimer’s Disease (AD) is a family of brain disorders usually found in elderly patients and is the most common cause of dementia. AD is characterized by slow, progressive loss of brain function, notable lapses in memory, disorientation, confusion, mood swings, changes in personality, language problems, such as difficulty in finding the right words for everyday objects, loss of behavioral inhibitions and motivation and paranoia. The course of AD varies widely, and the duration of illness can range from a few years to over 20 years. During this period the parts of the brain that control memory and thinking are among the first affected, followed by other brain changes that ultimately result in brain cell death.82
AD is characterized by distinct neuropathological changes in brain tissues and cells. Among the most notable are the appearance of plaques and tangles of neurofibrils within brain nerve cells that affect synapses and nerve-nerve cell communication. These structural alterations involve the deposition of altered amyloid proteins.83, 84 Although the cause of AD is not known, the formation of the amyloid plaques and neurofibrillary tangles may be due to genetic defects and resulting changes in the structure of beta amyloid proteins. This in turn may be caused by chemicals or other toxic events, inflammatory responses, excess oxidative stress and increases in reactive oxygen species, loss of nerve trophic factors and reductions in nerve cell transmission.83-87
Recently AD brain infections have become important.88-90 For example, one pathogen that has attracted considerable attention is C. pneumoniae.91, 92 As mentioned above, this intracellular bacterium has a tropism for neural tissue, and it has been found at high incidence in the brains of AD patients by PCR and immunohistochemistry.92 C. pneumoniae has also been found in nerve cells in close proximity to neurofibrillary tangles.92, 93 Similarly to Mycoplasma species, C. pneumoniae can invade endothelial cells and promote the transmigration of monocytes through human brain endothelial cells into the brain parenchyma.94 C. pneumoniae has been found in the brains of most AD patients,91 and it has been cultured from AD brain tissue.95 Injection of C. pneumoniae into mice stimulates beta amyloid plaque formation.96 Although the data are compelling, some investigators have not found C. pneumoniae infections in AD.97, 98
AD patients also have other bacterial infections, such as B. burgdorferi.99 Using serology, culture, Western blot and immunofluorenscence methods this Lyme Disease infection has been examined in AD.100, 101 Not all researchers, however, have found evidence of B. burgdorferi in AD patients.102, 103 The presence of intracellular infections like B. burgdorferi in AD patients has been proposed to be a primary event in the formation of AD beta amyloid plaques. This is thought to occur by the formation of “congophilic cores” that attract beta amyloid materials.104 Multiple reports indicate that AD nerve cells are often positive for B. burgdorferi, indicating that this intracellular bacteria could be important in the pathogenesis of AD.99, 100, 104, 105
The hypothesis in AD that intracellular microorganisms could provide “cores” for the attraction of beta amyloid materials is appealing, but other factors, including the induction of reactive oxygen species, lipid peroxidation and the breakdown of the lysosomal membranes releasing lysosomal hydrolases, are also thought to be important in beta amyloid deposition.105 That infections may be important in AD pathogenesis is attractive; however, some negative reports have not confirmed the presence of infections like B. burgdorferi in AD patients.99-101 This suggests that the infection theory, although compelling, remains controversial.102, 105
Herpes virus infections have also been found in AD,especially HSV-1.106, 107 Previously it was determined that HSV-1 but not a related neurotrophic virus (varicella zoster virus) is present more often in AD brains, and this could be linked to AD patients who have the risk factor ApoE e4 allele.108, 109 HSV-1 is thought to be involved in the abnormal aggregation of beta amyloid fragments within the AD brain by reducing the amount of full-length beta amyloid precursor protein and increasing the amounts of their fragments.110 HSV-1 infection of glial and neuronal cells results in a dramatic increase in the intracellular levels of beta amyloid forms, whereas the levels of native beta amyloid precursor protein are decreased.111 This is similar to what has been found in mice infected with HSV-1, indicating that HSV-1 is probably involved directly in the development of senile-associated plaques. Another herpes virus, HHV-6, has also been found in AD patients, but it is thought that this virus is not directly involved in AD pathogenesis. HHV-6 may exacerbate the effects of HSV-1 in AD ApoE e4 carriers.112
Other infections have been found in AD patients, for example, C. pneumoniae, Helicobacter pylori amongst others.113 It has been proposed that such infections may act as a trigger or co-factor in AD.114 Although experimental evidence that pathogens can elicit the neuropathological changes and cognitive deficits that characterize AD is lacking, this approach may yield interesting and important results. These authors also stressed that systemic infections must be considered as potential contributors to the pathogenesis of AD.114
Parkinson’s disease (PD) is characterized by akinesia, muscular rigidity and resting tremor.103 In addition, autonomic dysfunction, olfactory disturbances, depression, sensory and sleep disturbances and frequently dementia characterize this disease.115 The pathology of PD indicates a progressive loss of the dopamine neurons of the substantia nigra together with the presence of Lewy bodies and alpha-synuclein. More extensive brain degeneration also occurs, from the medulla oblongata to the cerebral cortex.116, 117
Age-related inclusion bodies and protein aggregations or defects in their degradation characteristically occur in PD, but their role in PD pathogenesis remains unclear.117, 118 Some evidence suggests a relationship between PD and specific genetic changes, such as changes in the genes affecting mitochondria, protein degradation, organelle trafficking and vesicular fusion, and in proteins involved in oxidative stress or antioxidant function.102 Inflammation has also been associated with PD pathology.119
The pathogenesis of PD has been proposed to be due to multiple genetic and neurotoxic events that produce oxidative damage and cell death. In the case of PD the relevant targets of toxic events are neuromelanin-containing dopaminergic neurons of the substantia nigra.118, 120 A case-control study indicated that multiple environmental factors and genetic background were statistically related risk factors for PD.121 Prominent among these were long-term toxic exposures and trauma early in life.122 For example,early life exposure to brain injury, chemicals and/or infections may initiate a cyclic inflammatory process involving oxidative damage, excitotoxicity, mitochondrial dysfunction and altered proteolysis that later in life results in substantia nigra neuron death.123, 124
A role for chronic infections in PD pathogenesis has been proposed.123, 124 One infection found in PD that has aroused considerable interest is the presence of chronic gastrointestinal Helicobacter pylori.125 Indeed, treatment of this infection offers relief to late stage cachexia in PD patients receiving L-dopa.126 Helicobacter pylori-infected PD patients showed reduced L-dopa absorption and increased clinical disability,127 whereas treatment of this infection increased L-dopa absorption and decreased clinical disability.128 H. pylori may not be directly involved in the pathogenesis of PD, but its systemic presence could affect the progression and treatment of PD, probably by stimulating inflammation and autoimmunity.128
Chronic infections in PD have been linked to inflammation and autoimmune responses.129-131 Experimental models of PD have been developed using neurological viral or bacterial infections to initiate the pathogenic process.132, 133 Spirochetes have also been found in Lewy bodies of PD patients.30 Other infections, such as viral encephalitis,134 AIDS-associated opportunistic infections of the basal ganglia,135 coronavirus,136 among other infections,68, 137, 138 have been found in PD and could be important in stimulating inflammation and autoimmune responses. It has been stressed that additional research will be necessary to establish whether a causal link exists between PD and chronic infections.139
Autism spectrum disorders
ASD, such as autism, Asperger’s syndrome, etc., are neurobehavioral diseases of primarily the young where patients generally suffer from an inability to communicate properly, form relationships with others and respond appropriately to their environment. Such patients do not all share the same signs and symptoms but tend to share certain social, communication, motor and sensory problems that affect their behavior in predictable ways. These patients often display repetitive actions and develop troublesome fixations with specific objects, and they are often painfully sensitive to certain sounds, tastes and smells.140, 141
ASD cases are likely to be caused by multiple factors, including genetic defects, heavy metal, chemical and biological exposures, among other important events, which are probably different in each patient. ASD patients appear to have similarities in genetic defects and environmental exposures that are important in patient morbidity or in illness progression.5-8, 140-142
Chronic infections appear to be an important element in the development of ASD.6, 16, 143, 144 In ASD patients more than 50 different bacterial, viral and fungal infections have been found,6 some apparently more important than others in causing symptoms. It has been known for some time that ASD patients have a number of nonspecific chronic signs and symptoms, such as fatigue, headaches, gastrointestinal, vision problems, occasional intermittent low-grade fevers and other signs and symptoms that are generally excluded in the diagnosis of ASD but are consistent with the presence of infections.143 Indeed, increased titres to various viruses as well as bacterial and fungal infections have been commonly seen in ASD patients.6, 16, 19, 143-145 Not withstanding these reports, epidemiological evidence for an association of childhood infections in the first two years of life and ASD has been mixed.146
Environmental exposures to chemicals and heavy metals also appear to be important in the development of ASD.140, 141, 147, 148 The relationship between ASD and heavy metals may involve the role of multiple vaccines in ASD pathogenesis.130, 141 ASD patients often show their first signs and symptoms after multiple childhood immunizations, and the sharp increase in Autism rates occurred only after the multiple MMR vaccine came into widespread use.141 In some states in the U.S. children receive as many as 33 vaccines before they can enroll in school.140 Such vaccines can contain mercury and other toxic preservatives, and some may also contain contaminating bacteria, as found in veterinary vaccines.149
There are very few studies that have followed the transmission of infections and subsequent autism. Previously we found that veterans of the Gulf War with chronic fatiguing illnesses (Gulf War illnesses, GWI) exhibited multiple nonspecific signs and symptoms similar to chronic fatigue syndrome/myalgic encephalomyopathy (CFS/ME).150, 151 After returning to the home with GWI, their children subsequently became symptomatic, and these children were often diagnosed with ASD.152, 153 Symptomatic children (mostly diagnosed with ASD) were infected with the same Mycoplasma species, M. fermentans, that was found in the veterans and their symptomatic family members, and this was not seen in aged-matched control subjects or in military families without GWI. In the GWI families some non-symptomatic family members did have mycoplasmal infections (~10%), but this was not significantly different from the incidence of mycoplasmal infections in healthy control subjects.152, 153
Subsequently ASD patients who were not in military families were examined for systemic mycoplasmal infections.153 The majority (~54%) were positive for mycoplasmal infections. However, in contrast to the children of GWI patients who for the most part had only M. fermentans, the civilian children tested positive for a variety of Mycoplasma species. We also tested a few siblings without apparent signs and symptoms, and for the most part few had these infections.153 In another study we examined the blood of ASD patients from Central and Southern California and found that a large subset (>58%) of patients showed evidence of Mycoplasma infections compared to age-matched control subjects (Odds Ratio=13.8, p<0.001).19 ASD patients were also examined for C. pneumoniae (8.3% positive, Odds Ratio=5.6, p<0.01) and HHV-6 (29.2% positive, Odds Ratio=4.5, p<0.01). The results indicated that a large subset of ASD patients display evidence of bacterial and/or viral infections (Odds Ratio=16.5, p<0.001).19
ASD patients have been examined for B. burgdorferi infections.154 Various studies revealed that 22-30% of ASD patients (N=76) have Borrelia infections.6, 154 The incidence of Borrelia infections in ASD patients may be related to Lyme disease distribution, with some Lyme-intense areas having high prevalence, and other areas having a low prevalence. Other infections, such as Lyme-associated Bartonella, Babesia, Ehrlichia and non-Lyme-associated CMV, Plasmodium species, Toxoplasma species and Treponema species may also be associated with ASD.6
Final comments to part 1
When neurological symptoms are present, infections of the CNS must be considered. Brain infections can stimulate glial responses, and the presence of viral and bacterial infections in nerve cells, can stimulate autoimmune responses against nerve cell antigens as well as the infections within them.155 For example, in MS some 20 different bacterial and viral infections have been found, but the link between these infections and the pathogenesis of MS is still being debated.16, 47, 75 One or even a few types of infections cannot be causally linked to MS, and the reason for this is that there may be too many possibilities. No one infection or a group of infections needs to be the trigger in MS to be important in the pathogenesis of MS. In time combinations of certain infections may eventually be identified at least in a subset of MS patients, and this will allow the development of new therapeutic approaches for many MS patients that are not recognized today.
One problem that is rarely discussed is the apparent disparity between the laboratory results from different laboratories. Often different laboratories cannot agree on types of infections found in various chronic diseases.47 There are a number of reasons for this, including differences in the source of materials, qualities of reagents and techniques used.16 Some procedures, such as PCR, have specific challenges that must be overcome in the handling of specimens, their stability, presence of interfering substances, contamination, sensitivity and specificity of the tests and interpretation of the results. Variability in results from different laboratories will remain a problem unless research groups work closely together to solve these problems. One example of how this has been overcome is a multi-centre research study on the presence of C. pneumoniae in the cerebrospinal fluid of clinically defined, mono-symptomatic MS patients.156 Sriram et al.156 conducted this diagnostic trial with good concordance of results between different laboratories. Cooperative studies such as this should eventually alleviate discrepancies in the types of infections found by different research groups.
This review continues in Part 2 with psychiatric diseases, autoimmune diseases, fatiguing illnesses, and other infectious diseases with neurological aspects and an overall discussion of the topic. 157

One of the findings noted by many physicians treating Lyme disease that was never treated, or Babesia or Bartonella, is serious personality and neurology troubles. This is no surprise when you realize the emotional centers and relational skills centers of the brain are infected with these infections in some people and this makes them into very sad hateful eccentric people. It is amazing to listen to respected physicians who treat people with tick infections. They seem to typically report the following tick infection personality changes or neurology changes:
Narcissism—they believe they have the answers, despite prolonged and failed treatment. They think they know areas they have no training in such as costs to be educated for NP, PA, DO, ND or MD. They act as if they know the costs to be an MD each year, costs to research or attend conferences, costs for any book, costs to do a blind study, costs to have lawyers, costs for malpractice insurance, costs for staffing, etc.
Entitlement—massive demands for time and huge expectations
Short term memory is decreased—so patients forget instructions
Rage—evidence of huge amounts of time not helping people, but attacking.
Weird posts on the motives of respected clinicians.
Black and White Thinking—past or current healers are the devil or great.
Slowed Learning—they read a book and do not seem to absorb large sections.
Criminal actions, e.g., stealing PDF books which has possible five year jail term, stealing identities, making extreme bizarre accusations, posting home addresses to provoke some attack or _________ on a physician, local politician or insurance staff who is not approving a treatment. I assume the writer or poster also wants harm to come to the family of these individuals.
Hate over fees—they do not appreciate offering treatment for a possibly fatal illness has massive risks. They have no knowledge of expenses just to run an office or lost income just publishing a small journal article. They suffer from a regressed primitive personality that wants the physician to be a mother and offer free unconditional love.
Trivia Complaints—small matters are made into matters worthy of immense time and hateful accusations which are amplified 20x from the brain pathology. Some actually hate some physicians, and instead of moving on and finding a good fit and getting well, they attack someone who is not meeting their perfection standards, which usually include taking insurance, very low rates and mother-like care with free emergency access and free email medicine.
Rape of Physician Boundaries—they want to take five physicians and rip them apart, and take the things they like in each one, to make a perfect MD that meets their standards.

Aim: Assessment of PCR procedure for proving of the Borrelia burgdorferi sensu lato DNA in nerve and skin forms of Lyme borreliosis. Methods: DNA from plasma, urine and CSF was isolated by QIAamp DNA mini kit. PCR was deigned as two-step amplification (nested-PCR). Each sample was tested in PCR for five target sequences: two were specific for plasmide genes encoding OspA and OspC proteins and three correlated with genes for 16SrDNA, flagellin and p66 protein. Results: Borrelial DNA was proved in 41 patients suffering from neuroborreliosis out of 56 (77.4 %), among 48 patients with erythema migrans (EM) were found 26 positive (54.2 %). After treatment the specific DNA was detected in 22 patients with neuroborreliosis (41.5 %) and 16 patients with EM (38.1 %). Three months after the treatment 23 patients were positive in both of groups (28.7 %) and next 3 months later the specific DNA was found in 6 (9.5 %). The highest rate of positive results was manifested by 16SrDNA target, lower and comparable results were obtained by OspA, C and flagellin primers, the lowest rate was in p66 system. Conclusion: The tested PCR proved specific DNA in all tested biological fluids in both of the clinical forms of Lyme borreliosis with a relatively high sensitivity. The proving of DNA can not be used for the assessment of the effect of treatment due to the long persistence of PCR positivity after antibiotic treatment. To achieve a sufficient diagnostic sensitivity of PCR it is desirable to use minimally two amplification systems in parallel.

Microglia are mediators of Borrelia burgdorferi-induced apoptosis in SH-SY5Y neuronal cells.

Inflammation has long been implicated as a contributor to pathogenesis in many CNS illnesses, including Lyme neuroborreliosis. Borrelia burgdorferi is the spirochete that causes Lyme disease and it is known to potently induce the production of inflammatory mediators in a variety of cells. In experiments where B. burgdorferi was co-cultured in vitro with primary microglia, we observed robust expression and release of IL-6 and IL-8, CCL2 (MCP-1), CCL3 (MIP-1alpha), CCL4 (MIP-1beta) and CCL5 (RANTES), but we detected no induction of microglial apoptosis. In contrast, SH-SY5Y (SY) neuroblastoma cells co-cultured with B. burgdorferi expressed negligible amounts of inflammatory mediators and also remained resistant to apoptosis. When SY cells were co-cultured with microglia and B. burgdorferi, significant neuronal apoptosis consistently occurred. Confocal microscopy imaging of these cell cultures stained for apoptosis and with cell type-specific markers confirmed that it was predominantly the SY cells that were dying. Microarray analysis demonstrated an intense microglia-mediated inflammatory response to B. burgdorferi including up-regulation in gene transcripts for TLR-2 and NFkappabeta. Surprisingly, a pathway that exhibited profound changes in regard to inflammatory signaling was triggering receptor expressed on myeloid cells-1 (TREM1). Significant transcript alterations in essential p53 pathway genes also occurred in SY cells cultured in the presence of microglia and B. burgdorferi, which indicated a shift from cell survival to preparation for apoptosis when compared to SY cells cultured in the presence of B. burgdorferi alone. Taken together, these findings indicate that B. burgdorferi is not directly toxic to SY cells; rather, these cells become distressed and die in the inflammatory surroundings generated by microglia through a bystander effect. If, as we hypothesized, neuronal apoptosis is the key pathogenic event in Lyme neuroborreliosis, then targeting microglial responses may be a significant therapeutic approach for the treatment of this form of Lyme disease.

Lyme borreliosis is a tick-borne spirochetal infection which affects the skin, joints, heart and nervous system. Children with a neuroborreliosis usually present with a facial nerve palsy or aseptic meningitis, but the spectrum also includes other rare manifestations. We report four unusual cases of childhood neuroborreliosis and show that seizures with regional leptomeningeal enhancement, acute transverse myelitis, meningoradiculitis with pain and paraesthesia and cranial nerve palsies other than facial nerve palsy can be the leading symptoms of children with neuroborreliosis. All children had serological evidence of an acute infection with Borrelia burgdorferi, a pleocytosis in the cerebrospinal fluid and a complete response to antibiotic treatment. An intrathecal synthesis of IgG antibodies was detected in three children. Thus, diagnostic work up in children with unusual neurological symptoms should include cerebrospinal fluid studies with determination of the white blood cell count and calculation of the antibody index against B. burgdorferi.

Department of Otolaryngology Head and Neck Surgery, University Medical School of Debrecen, Debrecen, Hungary.
Objective:We report an extremely rare case of recurrent laryngeal nerve paralysis due to subclinical Lyme borreliosis.Method:Case report presenting a 15-year-old girl referred with hoarseness and soft voice.Results:Right-sided recurrent laryngeal nerve paralysis was observed using videolaryngoscopy. Imaging was used to exclude intracranial, cervical and intrathoracic embryological lesions, vascular malformations and tumours. Laboratory and electrophysiological investigations were used to exclude inflammatory and paraneoplastic processes, endocrinopathy and metabolic disorders. Serological testing was positive for Lyme disease. Parenteral ceftriaxone therapy was commenced. The patient's nerve paralysis showed complete recovery on the seventh day of antibiotic treatment; this was confirmed by videolaryngoscopy.Conclusion:Recurrent laryngeal nerve paralysis is an extremely rare complication of neuroborreliosis associated with Lyme disease. In patients with recurrent laryngeal nerve paralysis in whom the clinical history is uncertain and the usual diagnostic methods give negative results, screening with anti-borrelia immunoglobulin M is suggested.

BACKGROUND: Lyme neuroborreliosis (LNB) may present as meningitis, cranial neuropathy, acute radiculoneuropathy or, rarely, as encephalomyelitis. We hypothesized that glia, upon exposure to Borrelia burgdorferi, the Lyme disease agent, produce inflammatory mediators that promote the acute cellular infiltration of early LNB. This inflammatory context could potentiate glial and neuronal apoptosis. METHODS: We inoculated live B. burgdorferi into the cisterna magna of rhesus macaques and examined the inflammatory changes induced in the central nervous system (CNS), and dorsal root nerves and ganglia (DRG). RESULTS: ELISA of the cerebrospinal fluid (CSF) showed elevated IL-6, IL-8, CCL2, and CXCL13 as early as one week post-inoculation, accompanied by primarily lymphocytic and monocytic pleocytosis. In contrast, onset of the acquired immune response, evidenced by anti-B. burgdorferi C6 serum antibodies, was first detectable after 3 weeks post-inoculation. CSF cell pellets and CNS tissues were culture-positive for B. burgdorferi. Histopathology revealed signs of acute LNB: severe multifocal leptomeningitis, radiculitis, and DRG inflammatory lesions. Immunofluorescence staining and confocal microscopy detected B. burgdorferi antigen in the CNS and DRG. IL-6 was observed in astrocytes and neurons in the spinal cord, and in neurons in the DRG of infected animals. CCL2 and CXCL13 were found in microglia as well as in endothelial cells, macrophages and T cells. Importantly, the DRG of infected animals showed significant satellite cell and neuronal apoptosis. CONCLUSION: Our results support the notion that innate responses of glia to B. burgdorferi initiate/mediate the inflammation seen in acute LNB, and show that neuronal apoptosis occurs in this context.

A variety of neurological syndromes has been described in neuroborreliosis: cranial nerve palsies, radiculopathy, axonal neuropathy, stroke, parkinsonism, transverse myelitis, supranuclear palsy, Guillain-Barr� syndrome, ... We report a case of neuroborreliosis with cervical myelitis presenting clinically as a lower motor neuron syndrome of the upper and lower limbs with proximal and distal pareses and atrophies as well as bulbar dysarthria and dysphagia. During the course of the disease the patient developed the clinical picture of a meningoencephalitis. After initiating ceftriaxone treatment the patient showed a complete recovery. In endemic regions for Lyme disease, in all neurological syndromes neuroborreliosis has to be excluded.

Remaining complaints 1 year after treatment for acute Lyme neuroborreliosis; frequency, pattern and risk factors.
Lj�stad U, Mygland A.
Department of Neurology, S�rlandet Hospital HF, Kristiansand, Norway.
Background and purpose: To chart remaining complaints 1 year after treatment for neuroborreliosis, and to identify risk factors for a non-favorable outcome. Methods: We followed patients treated for neuroborreliosis prospectively, and assessed outcome by a composite clinical score. The impact on outcome of clinical, demographic and laboratory factors were analyzed by univariate analyses and logistic regression. Results: Out of 85 patients 41 (48%) had remaining complaints; 14 had objective findings and 27 subjective symptoms. Remaining complaints were associated with pre-treatment symptom duration >/=6 weeks (OR = 4.062, P = 0.044), high pre-treatment cerebrospinal fluid (CSF) cell count (OR = 1.005, P = 0.001), and female gender (OR = 3.218, P = 0.025). Presence of CSF oligoclonal bands (OCBs) was not analyzed in the logistic regression model due to many missing observations, but was found to be more frequent both pre-treatment (P = 0.004) and after 12 months (P = 0.015) among patients with remaining complaints as compared to patients with complete recovery. Further evaluation showed that objective remaining findings, and not subjective symptoms, were associated with pre-treatment symptom duration >/=6 weeks. No difference in outcome was observed between patients treated with IV ceftriaxone and patients treated with oral doxycycline. Conclusion: Remaining complaints are common after neuroborreliosis. The majority of the complaints are subjective. Pre-treatment symptom duration >/=6 weeks, high pre-treatment CSF cell count, and female gender seem to be risk factors for remaining complaints. Presence of CSF OCBs may also predict a non-favorable outcome, but this should be further studied. Whether subjective and objective complaints are associated with different risk factors is also an issue for future studies.

We studied the T-cell reactivity to overlapping peptides of B. garinii OspA, in order to locate possible immunodominant T-cell epitopes in neuroborreliosis. Cells from cerebrospinal fluid (CSF) and blood from 39 patients with neuroborreliosis and 31 controls were stimulated with 31 overlapping peptides, and interferon-gamma secreting cells were detected by ELISPOT. The peptides OspA(17-36), OspA(49-68), OspA(105-124), OspA(137-156), OspA(193-212) and OspA(233-252) showed the highest frequency of positive responses, being positive in CSF from 38% to 50% of patients with neuroborreliosis. These peptides also elicited higher responses in CSF compared with controls (P = 0.004). CSF cells more often showed positive responses to these peptides than blood cells (P = 0.001), in line with a compartmentalization to the central nervous system. Thus, a set of potential T-cell epitopes were identified in CSF cells from patients with neuroborreliosis. Further studies may reveal whether these epitopes can be used diagnostically and studies involving HLA interactions may show their possible pathogenetic importance.

Neuro-lyme disease: MR imaging findings.
Agarwal R, Sze G.
Department of Diagnostic Radiology, Yale University School of Medicine, New Haven, CT 06520, USA.
PURPOSE: To describe the neuroimaging manifestations of Lyme disease at magnetic resonance (MR) imaging of the brain. MATERIALS AND METHODS: Institutional review board approval was obtained and HIPAA compliance was followed. This study retrospectively reviewed the MR imaging findings of all patients seen from 1993 to 2007 in whom neuro-Lyme disease was suspected and who were referred for MR imaging of the brain for the evaluation of neurologic symptoms. RESULTS: Of 392 patients suspected of having neuro-Lyme disease, 66 patients proved to have the disease on the basis of clinical criteria, serologic results, and response to treatment. Seven of these 66 patients showed foci of T2 prolongation in the cerebral white matter, one had an enhancing lesion with edema, and three demonstrated nerve-root or meningeal enhancement. Of the seven patients with foci of T2 prolongation in the white matter, three were an age at which white matter findings due to small-vessel disease are common. CONCLUSION: In cases of nerve-root or meningeal enhancement, Lyme disease should be considered in the differential diagnosis in the proper clinical setting.

Lyme borreliosis: a European perspective on diagnosis and clinical management.
Stanek G, Strle F.
Department of Hygiene and Medical Microbiology, Medical University of Vienna, Vienna, Austria. email@example.com
PURPOSE OF REVIEW: Lyme borreliosis has been widely recognized in Europe, but diagnostic and therapy concepts are still a matter for discussion. False-positive microbiologic results can lead to unnecessary antibiotic treatment, which even in genuine cases is sometimes unnecessarily prolonged. This review addresses new research on diagnosis, treatment, and eco-epidemiology. RECENT FINDINGS: Recent research work in Europe since the last annual review has mostly dealt with diagnostic concepts. Improvement of serology has been achieved by use of multiple recombinant or peptide antigens, or of just the most frequently targeted antigen for detection of specific immunoglobulin G or immunoglobulin M antibodies to Borrelia burgdorferi sensu lato, the causative agent of Lyme borreliosis. Concerning management of the disease, early work on the efficacy of oral treatment of Lyme neuroborreliosis has been confirmed. Studies on the ecology of the vectors and pathogens have elucidated aspects of epidemiology. SUMMARY: Widespread awareness of Lyme borreliosis in Europe continues to grow due to increasing numbers of medical publications, information on the Internet, and from the media and patient support groups. The emphasis in scientific and medical publications has been on improvements in laboratory diagnostics, confirmation of therapeutic protocols, and the ecology of the vectors and pathogens.

BACKGROUND: Lyme disease is the most frequent tick-borne infectious disease in Europe. The discovery of the causative pathogen Borrelia burgdorferi in 1982 opened the way for the firm diagnosis of diseases in several clinical disciplines and for causal antibiotic therapy. At the same time, speculation regarding links between Borrelia infection and a variety of nonspecific symptoms and disorders resulted in overdiagnosis and overtreatment of suspected Lyme disease. METHOD: The authors conducted a selective review of the literature, including various national and international guidelines. RESULTS: The spirochete Borrelia burgdorferi sensu lato is present in approximately 5% to 35% of sheep ticks (Ixodes ricinus) in Germany, depending on the region. In contrast to North America, different genospecies are found in Europe. The most frequent clinical manifestation of Borrelia infection is erythema migrans, followed by neuroborreliosis, arthritis, acrodermatitis chronica atrophicans, and lymphocytosis benigna cutis. Diagnosis is made on the basis of the clinical symptoms, and in stages II and III by detection of Borrelia-specific antibodies. In adults erythema migrans is treated with doxycycline, in children with amoxicillin. The standard treatment of neuroborreliosis is third-generation cephalosporins. CONCLUSIONS: After appropriate antibiotic therapy, the outcome is favorable. In approximately 95% of cases neuroborreliosis is cured without long-term sequelae. When chronic borreliosis is suspected, other potential causes of the clinical syndrome must be painstakingly excluded.

Neuroborreliosis is easily diagnosed by means of clinical symptoms and laboratory findings. Guiding symptoms are radicular pain and pareses of the extremities and the facial nerve. There is a great number of further less frequently occurring neurological symptoms, which can be attributed to a borrelial infection only by appropriate investigations of the CSF. Radiculitis is cured adequately by oral doxycycline while symptoms of the central nervous system are probably better treated intravenously by ceftriaxone, cefotaxime or penicillin G. Post-Lyme syndrome is a diffuse description of non-specific complaints, which are not the explicit result of a former infection with B. burgdorferi. As further antibiotics do not help and the CSF is unremarkable in most patients, a persistent infection with B. burgdorferi s.l. in all probability can be excluded.

Human brain microvascular endothelial cell traversal by Borrelia burgdorferi requires calcium signaling.
Grab DJ, Nyarko E, Nikolskaia OV, Kim YV, Dumler JS.
Department of Pediatrics, The Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA. firstname.lastname@example.org
Neurological manifestations of Lyme disease (or neuroborreliosis) occur variably and while it is clear that Borrelia burgdorferi can invade the nervous system, how it does so is not well understood. Pathogen penetration through the blood brain barrier (BBB) is often influenced by calcium signaling in the endothelial cells triggered by extracellular host-pathogen interactions. We examined the traversal of B. burgdorferi across the human BBB using in vitro model systems constructed of human brain microvascular endothelial cells (HBMEC) grown on Costar Transwell inserts. Pretreatment of the cell monolayers with BAPTA-AM (an intracellular calcium chelator) or phospholipase C (PLC) inhibitor U73122 inhibited B. burgdorferi transmigration. By 5 h, BAPTA-AM significantly inhibited (82-99%; p <0.017) spirochete traversal of HBMEC compared to DMSO controls. Spirochete traversal was almost totally blocked (> or =99%; p <0.017) after pretreatment with the PLC-beta inhibitor U73122 as a result of barrier tightening based on electric cell-substrate impedance sensing (ECIS). The data suggest a role for calcium signaling in CNS spirochete invasion through endothelial cell barriers.

[Epidemiology of Lyme borreliosis and neuroborreliosis in France]
[Article in French]
D�partement de neurologie, CMRR, h�pitaux universitaires de Strasbourg, France. Frederic.Blanc@chru-strasbourg.fr
Lyme borreliosis (LB) is a systemic disease called neuroborreliosis (NB) when neurological symptoms are pre-eminent. LB is a zoonosis caused by Borrelia bacteria transmitted by Ixodes tick-bite. Because of the absence of a national registry, epidemiology of LB in France is not well known. Moreover, diagnosis of NB may be difficult because of the various clinical forms. Acute meningoradiculitis is the most common presentation, but pauci-symptomatic meningitis, encephalitis, myelitis, polyneuropathy, cerebrovascular involvement, and rarely chronic encephalomyelitis are also described. The vector Ixodes ricinus (I. ricinus) is found throughout metropolitan France excepting border areas of the Mediterranean seaside and in regions with an altitude above 1500 meters. In France, the Borrelia infestation rate of Ixodes is 7% with wide disparity between administrative districts. Prospective work in 1999-2000 by 875 general practitioners participating in the "Sentinel" network established the estimated incidence of BL (9.4/100 000) and of NB (0.6/100 000) in France. Incidence is higher in certain regions: in Alsace, prospective work by 419 general practitioners and specialists in cooperation with the national surveillance agency (Institut national de veille sanitaire), estimated BL incidence at 86 to 200/100 000 inhabitants and NB at 10/100 000. Thus, although globally France is a country with a moderate risk for LB, some regions such as Limousin, Auvergne, Lorraine and Alsace, have a high risk of LB, comparable to countries in the northeastern Europe such as Germany and Sweden.

Perineuritis is an unusual cause of direct peripheral nerve injury. We describe the clinicopathologic features of a 56-year-old man with mononeuritis multiplex due to Lyme disease; sural nerve biopsy demonstrated florid perineuritis. Treatment with intravenous ceftriaxone resulted in marked neurologic improvement. This study supports the notion that perineuritis forms part of the pathogenesis in acute Lyme neuroborreliosis.

AIM: Except bacterial meningitis, the agents causing acute central nervous system (CNS) infections in children are disclosed in only approximately half of the cases, and even less in encephalitis. We studied the potential of modern microbiological assays to improve this poor situation. METHODS: In a prospective study during 3 years, all children attending hospital with suspected CNS infection were examined using a wide collection of microbiological tests using samples from the cerebrospinal fluid, serum, nasal swabs and stool. RESULTS: Among 213 patients, 66 (31%) cases suggested CNS infection and specific aetiology was identified in 56 patients. Of these microbiologically confirmed cases, viral meningitis/encephalitis was diagnosed in 25 (45%), bacterial meningitis in 21 (38%) and neuroborreliosis in 9 (16%) cases while 1 child had fungal infection. In meningitis patients, the causative agent was identified in 85% (35/41) cases and in encephalitis in 75% (12/16). The most common bacteria were Streptococcus agalactiae, Streptococcous pneumonie and Neisseria meningitidis, while the most frequently detected viruses were enteroviruses and varicella zoster virus. CONCLUSION: In 75% to 85% of paediatric CNS infections, specific microbiological diagnosis was obtained with modern laboratory techniques. The results pose a basis for prudent approach to these potentially serious diseases.

CONTEXT: There is controversy regarding whether objective neurobiological abnormalities exist after intensive antibiotic treatment for Lyme disease. OBJECTIVES: To determine whether patients with a history of well-characterized Lyme disease and persistent cognitive deficit show abnormalities in global or topographic distributions of regional cerebral blood flow (rCBF) or cerebral metabolic rate (rCMR). DESIGN: Case-controlled study. SETTING: A university medical center. PARTICIPANTS: A total of 35 patients and 17 healthy volunteers (controls). Patients had well-documented prior Lyme disease, a currently reactive IgG Western blot, prior treatment with at least 3 weeks of intravenous cephalosporin, and objective memory impairment. MAIN OUTCOME MEASURES: Patients with persistent Lyme encephalopathy were compared with age-, sex-, and education-matched controls. Fully quantified assessments of rCBF and rCMR for glucose were obtained while subjects were medication-free using positron emission tomography. The CBF was assessed in 2 resting room air conditions (without snorkel and with snorkel) and 1 challenge condition (room air enhanced with carbon dioxide, ie, hypercapnia). RESULTS: Statistical parametric mapping analyses revealed regional abnormalities in all rCBF and rCMR measurements that were consistent in location across imaging methods and primarily reflected hypoactivity. Deficits were noted in bilateral gray and white matter regions, primarily in the temporal, parietal, and limbic areas. Although diminished global hypercapnic CBF reactivity (P < .02) was suggestive of a component of vascular compromise, the close coupling between CBF and CMR suggests that the regional abnormalities are primarily metabolically driven. Patients did not differ from controls on global resting CBF and CMR measurements. CONCLUSIONS: Patients with persistent Lyme encephalopathy have objectively quantifiable topographic abnormalities in functional brain activity. These CBF and CMR reductions were observed in all measurement conditions. Future research should address whether this pattern is also seen in acute neurologic Lyme disease.

Comment in: Pediatrics. 2009 May;123(5):1408.
OBJECTIVE: Lyme meningitis is difficult to differentiate from other causes of aseptic meningitis in Lyme disease-endemic regions. Parenteral antibiotics are indicated for Lyme meningitis but not viral causes of aseptic meningitis. A clinical prediction model was developed to distinguish Lyme meningitis from other causes of aseptic meningitis. Our objective was to prospectively validate this model. METHODS: Children between 2 and 18 years of age presenting to Hasbro Children's Hospital from April through October of 2006 and 2007 were enrolled if a lumbar puncture for meningitis showed a cerebrospinal fluid white blood cell count of >8 cells per microL. Cerebrospinal fluid was sent for Lyme antibody testing. The probability of Lyme meningitis was calculated by using the percentage of cerebrospinal fluid mononuclear cells, duration of headache, and presence of cranial neuropathy by using the prediction model. Definite Lyme meningitis cases were defined as cerebrospinal fluid pleocytosis with (1) positive Lyme serology confirmed by immunoblot or (2) erythema migrans rash. Possible Lyme meningitis cases were defined as cerebrospinal fluid pleocytosis with positive cerebrospinal fluid Lyme antibody. Sensitivity, specificity, and likelihood ratios for definite and possible Lyme meningitis were determined by using 10% increments of calculated probability of Lyme meningitis. RESULTS: Fifty children were enrolled, including 14 children with definite Lyme meningitis, 6 with possible Lyme meningitis, and 30 with aseptic meningitis. A calculated probability of <10% for Lyme meningitis had a negative likelihood ratio of 0.006 for definite and possible Lyme meningitis cases. A calculated probability of >50% for Lyme meningitis had a positive likelihood ratio of 100 using these definitions. CONCLUSIONS: A clinical prediction model using the percentage of cerebrospinal fluid mononuclear cells, headache duration, and presence of cranial neuropathy can differentiate children with Lyme meningitis from children with aseptic meningitis. Our findings suggest categories of low (<10%), indeterminate (10%-50%), and high (>50%) probability of Lyme meningitis.

Lyme borreliosis is a multi-system infectious disease that primarily affects the skin, nervous system, heart, and joints. It is caused by the tick-borne spirochete Borrelia burgdorferi sensu lato. Diagnosis is made on the basis of clinical symptoms and supported by a positive serology. Antibiotic therapy should be started immediately after the diagnosis has been established and is administered according to stage and symptoms of the disease. Doxycycline, amoxicillin, and ceftriaxone are the antibiotics of choice. Early Lyme disease is almost always cured by one antibiotic course that also prevents subsequent disease manifestations. After antibiotic therapy of late disease manifestations, symptoms resolve only slowly and remission is usually achieved after weeks or even months. Chronic or therapy-resistant disease courses and residual symptoms after therapy are rare.

The C6 Lyme antibody test has low sensitivity for antibody detection in cerebrospinal fluid.
Vermeersch P, Resseler S, Nackers E, Lagrou K.
University Hospitals Leuven, Belgium.
Our aim was to evaluate the performance of the commercial Immunetics C6 Lyme ELISA assay as a screening assay for anti-Borrelia burgdorferi antibodies in cerebrospinal fluid (CSF). Sensitivity of C6 ELISA was determined in 28 consecutive patients who were diagnosed with neuroborreliosis and had evidence for intrathecal antibody synthesis on immunoblot analysis. The presence of additional bands in CSF or of bands with a stronger intensity in CSF compared with serum was considered evidence of intrathecal synthesis. All 28 patients tested borderline or positive with C6 ELISA on serum. Of the 28 CSF samples, 17 (61%) and 19 (68%) tested positive with C6 ELISA using a threshold of 0.9 and 0.5 (optical density/cutoff). The C6 Lyme ELISA tested has a low sensitivity for antibody detection in cerebrospinal fluid compared with immunoblot analysis.

Nervous system lyme disease: diagnosis and treatment.
Department of Neurosciences, Atlantic Neuroscience Institute, Summit, NJ, USA.
Lyme disease, the multisystem infectious disease caused by the tickborne spirochete Borrelia burgdorferi, frequently affects the peripheral and central nervous systems. The earliest indication of Lyme disease infection is usually erythema migrans. This large, typically macular erythema, often with a target-like pattern of concentric pale and red circles, gradually enlarges day by day, potentially reaching many centimeters in diameter. In a significant proportion of infected individuals, an acute disseminated phase leads to seeding elsewhere in the body. Up to 5% of patients develop cardiac involvement. In about 10% to 15% of patients, the nervous system becomes symptomatically involved. Current serologic diagnostic tools are quite useful, and standard treatment regimens are highly effective. Oral antimicrobials have been shown to be effective in European neuroborreliosis and presumably are equally potent in North American patients. Long-term antibiotic treatment does not provide any additional lasting improvement, but it is frequently associated with significant morbidity.

What are the indications for lumbar puncture in patients with Lyme disease?
Rupprecht TA, Pfister HW.
Department of Neurology, Ludwig-Maximilians University, Munich, Germany.
Lyme neuroborreliosis (LNB) is a tick-borne disease of the nervous system, caused by the spirochete Borrelia burgdorferi. Having entered the host at the site of the tick bite, the spirochetes can initially cause a local inflammatory reaction, called erythema migrans. If left untreated, the Borrelia can disseminate in the second stage of the disease and invade the central nervous system, causing LNB. The diagnosis of LNB is based on a compatible clinical picture (meningitis, cranial neuritis or radiculoneuritis), lymphocytic pleocytosis in the cerebrospinal fluid (CSF) and intrathecal Borrelia burgdorferi-specific antibody production. As the clinical picture of LNB may be unspecific, a lumbar puncture to analyze the CSF is usually mandatory for confirmation of the suspected diagnosis. The indications for a lumbar puncture and the limitations of the different diagnostic procedures are the main topics of this review. In addition, a short overview of the epidemiology and the therapeutic principles of LNB is given. Copyright 2009 S. Karger AG, Basel.

Treatment and prevention of Lyme disease.
Service des Maladies Infectieuses et Tropicales, H�pitaux Universitaires de Strasbourg, Strasbourg, France. firstname.lastname@example.org
Randomized controlled trials have ascertained the efficiency of antibiotics in treating erythema migrans, the hallmark of early stage Lyme borreliosis. Oral amoxicillin and doxycycline are first-line treatment options, though phenoxymethylpenicillin, cefuroxime axetil and azithromycin are alternative second-line options. Treatments for secondary and tertiary Lyme borreliosis are more poorly documented, and antibiotics are not always effective. This is due to the unique pathophysiology of late Lyme borreliosis, which involves not only bacterial infection, but also immunological response. Since there is no completely reliable method of diagnosis, it is difficult to choose the proper treatment and to evaluate treatment efficacy. However, numerous studies have shown that ceftriaxone and doxycycline are the 2 most efficient antibiotics, particularly in Lyme arthritis and in neuroborreliosis. In late Lyme borreliosis, these antibiotics are less efficient, and different treatment schemes with variations in dosage or duration did not produce convincing results. Copyright 2009 S.

[Article in Hungarian]
Kullancsbetegs�gek Ambulanci�ja, Budapest, Visegr�di u. 14. 1132. firstname.lastname@example.org
We recognized the first Hungarian Lyme patients just 25 years ago, in 1984. It was exactly 20 years ago, when we opened the Lyme Disease Outpatient Service at the Central (L�szl�) Hospital for Infectious Diseases. 15 years ago we established the financially independent Center for Tick-borne Diseases. The milestones of this work at the Center for Tick-borne Diseases are the description of a new tick-borne rickettsial illness (tick-borne lymphadenopathy), development of a Lyme immunoblot kit and an automated immunoblot reader. We described a simple and reliable method for detection of intrathecal borrelia antibody synthesis which is necessary for the diagnosis of neuroborreliosis. We also developed and routinely apply the comparative immunoblot assay for the evaluation of serological progression and/or regression, which can help the clinicians to decide whether a serological reaction is resulted from a previous healed or an active borrelia infection. We studied the pregnancy outcome of borrelia infected mothers and provided that untreated borrelia infection is associated with higher chance of adverse pregnancy outcome.

Lyme disease has a worldwide distribution and is the most common vector-borne disease in the United States. Incidence, clinical manifestations, and presentations vary by geography, season, and recreational habits. Lyme neuroborreliosis (LNB) is neurologic involvement secondary to systemic infection by the spirochete Borrelia burgdorferi in the United States and by Borrelia garinii or Borrelia afzelii species in Europe. Enhanced awareness of the clinical presentation of Lyme disease allows inclusion of LNB in the imaging differential diagnosis of facial neuritis, multiple enhancing cranial nerves, enhancing noncompressive radiculitis, and pediatric leptomeningitis with white matter hyperintensities on MR imaging. The MR imaging white matter appearance of successfully treated LNB and multiple sclerosis display sufficient similarity to suggest a common autoimmune pathogenesis for both. This review highlights differences in the epidemiology, clinical manifestations, diagnosis, and management of Lyme disease in the United States, Europe, and Asia, with an emphasis on neurologic manifestations and neuroimaging.

In this study, the membrane lipids of B. burgdorferi were separated into 16 fractions; the components in each fraction were identified, and the immunogenicity of each fraction was determined by ELISA using sera from Lyme disease patients. Only the 2 glycolipids, acylated cholesteryl galactoside (ACG, BbGL-I) and monogalactosyl diacylglycerol (MgalD, BbGL-II), were immunogenic. Early in the infection, 24 of 84 patients (29%) who were convalescent from erythema migrans and 19 of the 35 patients (54%) with neuroborreliosis had weak IgG responses to purified MgalD, and a smaller percentage of patients had early responses to synthetic ACG. However, almost all of 75 patients with Lyme arthritis, a late disease manifestation, had strong IgG reactivity with both glycolipids. Thus, almost all patients with Lyme arthritis have strong IgG antibody responses to B. burgdorferi glycolipid antigens.

Comment in: Eur J Neurol. 2009 May;16(5):e102.
BACKGROUND: Tumefactive demyelinating disease (TDD) is a rare primary demyelinating disease with diagnostic and therapeutic challenges. METHODS AND RESULTS: We report a 50-year old woman with TDD successfully treated with decompressive craniectomy and corticosteroids. The patient presented with seizures, subacute progressive hemispheric syndrome, and a tumourlike abnormality on MRI. Demyelinating disease was initially considered unlikely. Due to a rapidly evolving herniation syndrome hemicraniectomy was performed. Outcome was favourable with only very mild neurological deficits 6 weeks later. CONCLUSION: TDD should be considered as a differential diagnosis in tumour-like presentations, and appears to have distinctive neuroimaging features. In the advent of treatement failure from high dose corticosteroids and plasmapheresis and development of severe mass effect, decompressive hemicraniectomy is an important treatment option.

Borreliosis is a multisystem infection, which in the absence of adequate diagnosis and clinical management, may develop towards various clinical forms of chronic pathology. Due to the heterogeneity of clinical manifestations it is known under more names: erythema migrans, Lyme disease, neuroborreliosis etc. MATERIAL AND METHOD: Taking into account the present interest and the weight in pathology of syndromes consistent with the suspicion of a Borrelia spp. infection, since 2002 we applied in current practice the investigation of this etiology. There have been investigated 481 subjects, clinically suspected of Borrelia spp. infection that had historical risk of tick bite and cases of serous meningitis, after exclusion of usual etiology. Tests were performed on ELISA kits with standardised immunoreagents and recently, for result validation, on Western immunoblot kits (WB). RESULTS: Our results revealed the Borrelia etiology in 32% of cases (27.96-36.29% CI = 95%) at the screening, value expressed by the persistent positivity of the specific immunoglobulins (Ig) IgM (80.5%) and IgM+IgG (19.5%). Historic infection, represented exclusively by IgG positivity, was present in 8.6% (5.87-11.98% CI = 95%) from the cases that were negative for IgM (68%, 63.71-72.04%, CI = 95%). This weight is superposable with the results obtained in investigating a comparable sample of healthy individuals (193 subjects with 6.74% historical IgG, 3.79-10.96%, CI = 95%). Based on these results, it can be considered that ELISA procedure is useful and of reliable prognosis value for screening the Borrelia spp. etiology, the next step, taking into account the higher sensitivity of WB, being WB procedure which is useful for confirmation of ELISA positive cases and for treatment efficiency surveillance. The results prove that Borrelia spp. infections are a public health issue, which due to the diversity of clinical manifestations and diagnosis difficulties need repeated and complex laboratory investigations.

Syphilis is a sexually transmitted disease caused by the spirochete Treponema pallidum. A chancre usually develops initially. Organ involvement and neurological complications may occur, sometimes several years after the initial exposure. We managed two patients with syphilis responsible for joint or neurological manifestations, diagnosed in 2008. One patient presented with oligoarthritis involving the knees and right elbow, coinciding with a maculopapular and pustular eruption. In the other patient, meningoradiculitis involving the T8, T9, and T10 metameres prompted a test for Lyme disease, which was weakly positive, leading to evaluation for false-positivity due to a cross-reaction. Neither patient was infected with the HIV.

Laboratory data in children with Lyme neuroborreliosis, relation to clinical presentation and duration of symptoms.
Tveitnes D, �ymar K, Nat�s O.
Departments of Paediatrics, University of Bergen, Norway.
The occurrence of IgM and IgG antibodies against Borrelia burgdoferi in serum and cerebrospinal fluid (CSF) and intrathecal synthesis of antibodies (antibody index) were studied in relation to clinical presentation and the duration of symptoms before diagnosis in 146 children diagnosed with neuroborreliosis. Lymphocytic meningitis was demonstrated in 141 of these children. Levels of white blood cells (WBC) and protein in CSF correlated significantly to numbers of d with symptoms. Children were divided into 3 clinical groups: A (n = 37): only cranial neuropathy; B (n = 68): both cranial neuropathy and other neurological symptoms; C (n = 41): neurological symptoms without cranial neuropathy. Levels of WBC and protein in CSF as well as the proportion of children with antibodies in serum and CSF were generally lowest in group A, intermediate in group B and highest in group C. The proportion of children with antibodies in serum and CSF and a positive antibody index was also related to duration of symptoms; the antibody index was present in 51% of children with symptoms < or = 7 d, and in 80% of children with symptoms > 7 d (p<0.01). The clinical presentation and duration of symptoms must be considered when interpreting laboratory data in children with suspected neuroborreliosis.

Department of Neurology, Sozialmedizinisches Zentrum Ost, Donauspital, Vienna, Austria. email@example.com
BACKGROUND: An 80-year-old woman presented with progressive cognitive decline and with a 6-month history of gait ataxia. Brain MRI depicted enlarged ventricles and periventricular lesions. Clinical improvement after CSF spinal tap test suggested a normal pressure hydrocephalus syndrome. But CSF pleocytosis with activated lymphocytes and plasma cells and intrathecal Borrelia burgdorferi specific antibody production led to the diagnosis of active Lyme neuroborreliosis. Clinical symptoms of NPH resolved after a course of ceftriaxone. METHODS: Neurological examination, MMSE, brain MRI, lumbar puncture, spinal tap test. RESULTS: Dementia due Borrelia burgdorferi infection with chronic meningitis was reversible after treatment with iv.2 g ceftriaxone per day for 4 weeks. CONCLUSIONS: Rare but treatable dementias must be diagnosed promptly to slow down or even reverse cognitive decline.

The aim of the study was evaluation of usefulness of cerebrospinal fluid (CSF) serotonin level examination in diagnostics of post-Lyme disease syndrome. The study was performed in 16 subjects. In all individuals CSF serotonin concentration was estimated on the 1st day of hospitalization. In patients with depressive and cognitive impairments, proved in neuropsychological tests, - group I--mean CSF serotonin concentration was 1,26 ng/ml, whereas in subjects without abnormalities in tests--group II--respectively--3,87 ng/ml. The difference of mean CSF serotonin levels was statistically significant (p<0,01). The obtained results indicate usefulness of this CSF parameter, besides neuropsychological tests, in objective evaluation of clinical state in patients with post-Lyme disease syndrome.

BACKGROUND: Neurological symptoms develop in 10-20% of children suffered borreliosis (LD). AIM OF THE STUDY: It was a presentation of motoric disturbances of neuroboreliosis in children. MATERIAL AND METHODS: Children with neuroborreliosis and other neurological diseases were admitted to the University hospital during 2005-2007. Of these 13 patients, there were 9 males and 4 females, ranging in age between 3-17 years. Neurological diagnostic was performed using ELISA Biomedica kit and western blot bands. A 2-6 week sequential treatment with either iv ceftazidime or amoxicillin and oral doxycycline or amoxicillin was provided. Children were monitored regularly during the next 4-36 months. RESULTS: The 13 children with neuroborreliosis constitute 0.5% of the pediatric neurology department's patients. The clinical manifestation of LD were usual and unusual from patient to patient. They included four cases of facial nerve paralysis (with bilateral paralysis in one case), in three cases transverse myelitis and in a single case, hemiparesis, and oculomotor nerve paresis. In 9/13 children motoric disturbances of neuroboreliosis was diagnosed indeed. The antibiotic treatment was successful in 6 patients and only partially effective in 3 children with facial nerve paralysis. CONCLUSION: The most common symptoms of neuroborreliosis in children was motoric dysfunction.

We report on four patients who experienced Parsonage-Turner syndrome as the first manifestation of Lyme disease. The clinical picture was typical, with acute shoulder pain followed rapidly by weakness and wasting of the shoulder girdle muscles. Electrophysiological testing showed denervation. A single patient reported erythema chronicum migrans after a tick bite. Examination of the cerebrospinal fluid showed lymphocytosis and protein elevation in 3 patients. Serological tests for Lyme disease were positive in the serum in all 4 patients and in the cerebrospinal fluid in 2 patients. Antibiotic therapy ensured a favorable outcome in all 4 cases. Two patients achieved a full recovery within 6 months. Parsonage-Turner syndrome should be added to the list of manifestations of neuroborreliosis. Serological tests for Lyme disease should be performed routinely in patients with Parsonage-Turner syndrome.

Service de Neurologie, Universit� catholique de Louvain, Brussels, Belgium.
We report the case of a 23-year-old male patient who suddenly developed right hemiparesis, cerebellar ataxia, dysarthria, and bilateral dysmetria. Brain magnetic resonance (MR) examination demonstrated hyperacute ischaemic lesions within the pons. CSF analysis revealed a high protein content, lymphocytic pleocytosis, and oligoclonal IgG bands not present in the serum. Elevated IgM and IgG anti-Borrelia burgdorferi antibodies were shown in both serum and CSF samples, associated with an intrathecal synthesis of these antibodies. Ischaemic CNS lesions have been rarely observed as the first manifestation of Lyme neuroborreliosis. The putative mechanism for parenchymal ischaemia is the local extension of inflammatory changes from meninges to the wall of penetrating arterioles.

Reinfection with Borrelia burgdorferi s.l., which is likely in highly exposed persons, has not been described in Poland so far. Symptoms of Lyme arthritis, preceded by typical skin lesion (erythema migrans) appeared in 46 years old women 5 years after successful treatment of borrelial meningitis. Re-appearance of symptoms of Lyme borreliosis following localized skin lesion, after a long asymptomatic period, as well as accompanying increase in specific antibodies, point to reinfection with Borrelia burgdorferi sensu lato. Different localization of systemic symptoms during two episodes of Lyme disease suggests infection with distinct genospecies of B. burgdorferi s.l. This case confirms risk of recurrent infections with different B. burgdorferi s.l. genospecies in inhabitants of highly endemic areas in the north-east of Poland, which may pose necessity of repeated antibiotic treatment.

Acute ataxia in a 4-year-old boy: a case of Lyme disease neuroborreliosis.
Lopez MD, Wise C.
Departments of Emergency Medicine and Pediatrics Medical College of Georgia, Augusta, CA 30912, USA. firstname.lastname@example.org
We present a case of a 4-year-old who presented to the emergency department with an unsteady gait for 2 days. Ataxia is a rare but known manifestation of cerebellar involvement in Lyme disease. A 4-year-old (17 kg) boy with no significant medical history presented to the emergency department (ED) with history of nonbloody emesis for 2 weeks and an unsteady gait for 2 days. Over the past 2 days, his gait had gotten progressively worse until he was unable to walk without assistance. The vomiting would usually occur 1 hour after eating meals. He had also complained of a single headache, which occurred approximately 10 days before admission. The headache did not occur in the early morning hours or wake him up from his sleep. His appetite for the weeks before admission had progressively decreased, and he had also become more irritable, especially when stimulated. He had increased fatigue for the week before presentation. His parents denied any fever, rhinorrhea, cough, diarrhea, rash, bruising, bleeding, or hematuria. The patient denied any abdominal pain or headache while in the ED.

Epidemiological situation of Lyme borreliosis in germany: surveillance data from six Eastern German States, 2002 to 2006.
F�l�p B, Poggensee G.
Department of Infectious Disease Epidemiology, Robert-Koch Institute, Berlin, Germany.
Lyme borreliosis is the most frequent vector-borne disease in Germany; however, in only six states in the eastern part of Germany (Berlin, Brandenburg, Mecklenburg Western Pomerania, Saxony, Saxony-Anhalt and Thuringia) is early Lyme disease (erythema migrans and early neuroborreliosis) a notifiable disease. Between 2002 and 2006, the incidence increased constantly; in 2002, the incidence per 100,000 inhabitants was 17.8 and rose by 110% to 37.3 in 2006. The incidence among the states varies greatly with Brandenburg accounting for the highest incidence (77.6 per 100,000 inhabitants) and Berlin for the lowest incidence (5.7 per 100,00 inhabitants). The age distribution is bimodal with incidence peaks in childhood between the ages 5 to 9 and in adulthood in the age group 65 to 69 years. In general, females are more frequently affected than males (55% versus 45%). Erythema migrans and early neuroborreliosis affected 20,787 patients (90%) and 799 patients (3%), respectively. Around 70% of all cases occurred between June and September. Further studies are needed to answer the question to which extent the annual increase can be related to a changing epidemiological situation or to other factors such as growing awareness, better diagnostic tools and changing recreational habits.

Clinical characteristics of childhood Lyme neuroborreliosis in an endemic area of northern Europe.
�ymar K, Tveitnes D.
Department of Paediatrics, Stavanger University Hospital, Stavanger, Norway. email@example.com
Neuroborreliosis may be caused by different species of Borrelia burgdorferi (BB) and the clinical presentation of neuroborreliosis in children may differ between geographical areas due to occurrence of different BB genospecies. The aim of this study was to evaluate the clinical characteristics in children with neuroborreliosis in an endemic area of Scandinavia. During 1996-2006, children with suspected neuroborreliosis referred to Stavanger University Hospital were investigated by a standard procedure including a lumbar puncture. A total of 143 children were diagnosed with neuroborreliosis, and all cases were diagnosed from April to December. The most common clinical presentations were symptoms of mild meningitis (75%) and/or facial nerve palsy (69%). Radicular pain was present in only 10 children. In all but 5 children, laboratory signs of meningitis were present. Erythema migrans preceded the neurological symptoms in only 27% of the children. In conclusion, we have found that in an endemic area of northern Europe, meningitis is present in the majority of children with neuroborreliosis, and that symptoms of a mild meningitis or facial nerve palsy are the most common presentations.

BACKGROUND: Evaluation of children with clinically suspected neuroborreliosis (NB) is difficult. With a prospective study design we wanted to characterize children with signs and symptoms indicative for NB, investigate clinical outcome and, if possible, identify factors of importance for recovery. MATERIAL/METHODS: Children being evaluated for NB (n = 177) in southeast Sweden were categorized into 3 groups: "confirmed neuroborreliosis" (41%) with Borrelia antibodies in the cerebrospinal fluid, "possible neuroborreliosis" (26%) with pleocytosis but no Borrelia antibodies in the cerebrospinal fluid, and "not determined" (33%) with no pleocytosis and no Borrelia antibodies in the cerebrospinal fluid. Antibiotic treatment was given to 69% of children. Patients were followed during 6 months and compared with a matched control group (n = 174). RESULTS: Clinical recovery at the 6-month follow-up (n = 177) was generally good and no patient was found to have recurrent or progressive neurologic symptoms. However, persistent facial nerve palsy caused dysfunctional and cosmetic problems in 11% of patients. Persistent nonspecific symptoms, such as headache and fatigue, were not more frequently reported in patients than in controls. Influence on daily life was reported to the same extent in patients and controls. Consequently, persistent headache and fatigue at follow-up should not be considered as attributable to NB. No prognostic factors could be identified. CONCLUSIONS: Clinical recovery was satisfactory in children being evaluated for NB although persistent symptoms from facial nerve palsy occurred. Persistent nonspecific symptoms, such as headache and fatigue, were not more frequently reported in patients than in controls.

BACKGROUND: Laboratory diagnostics in Lyme neuroborreliosis need improvement. We hereby investigate 4 new recombinant or peptide Borrelia antigens in cerebrospinal fluid in children with neuroborreliosis to evaluate their performance as diagnostic antigens. METHODS: An enzyme-linked immunosorbent assay was used to detect IgG antibodies to recombinant decorin binding protein A (DbpA), BBK32, outer surface protein C (OspC), and the invariable region 6 peptide (IR6). The recombinant antigens originated from 3 pathogenic subspecies; Borrelia afzelii, Borrelia garinii, and Borrelia burgdorferi sensu stricto. Cerebrospinal fluid and serum from children with clinical features indicative for neuroborreliosis (n = 57) were analyzed. Classification of patients was based on clinical symptoms and laboratory findings. Controls were children with other neurologic diseases (n = 20) and adult patients with no proven infection (n = 16). RESULTS: Sensitivity for DbpA was 82%, for BBK32 70%, for OspC 58% and for IR6 70%. Specificities were 94%, 100%, 97%, and 97%, respectively. No single antigen was superior. When new antigens were combined in a panel, sensitivity was 80% and specificity 100%. The reference flagella antigen showed a sensitivity of 60% and a specificity of 100%. Over all, the B. garinii related antigens dominated. CONCLUSIONS: Recombinant DbpA and BBK32 as well as the peptide antigen IR6 perform well in laboratory diagnostics of neuroborreliosis in children. New antigens seem to improve diagnostic performance when compared with the routine flagella antigen. If different antigens are combined in a panel to cover the antigenic diversity, sensitivity improves further and a specificity of 100% can be achieve.

BACKGROUND: Tests to determine serum antibody levels-the 2-tier sonicate immunoglobulin M (IgM) and immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) and Western blot method or the IgG of the variable major protein-like sequence-expressed (VlsE) sixth invariant region (C6) peptide ELISA method-are the major tests available for support of the diagnosis of Lyme disease. However, these tests have not been assessed prospectively. METHODS: We used these tests prospectively to determine serologic responses in 134 patients with various manifestations of Lyme disease, 89 patients with other illnesses (with or without a history of Lyme disease), and 136 healthy subjects from areas of endemicity and areas in which the infection was not endemic. RESULTS: With 2-tier tests and the C6 peptide ELISA, only approximately one-third of 76 patients with erythema migrans had results that were positive for IgM or IgG seroreactivity with Borrelia burgdorferi in acute-phase samples. During convalescence, 3-4 weeks later, almost two-thirds of patients had seroreactivity with the spirochete B. burgdorferi. The frequencies of seroreactivity were significantly greater among patients with spirochetal dissemination than they were among those who lacked evidence of disseminated disease. Of the 44 patients with Lyme disease who had neurologic, heart, or joint involvement, all had positive C6 peptide ELISA results, 42 had IgG responses with 2-tier tests, and 2 patients with facial palsy had only IgM responses. However, among the control groups, the IgG Western blot was slightly more specific than the C6 peptide ELISA. The differences between the 2 test systems (2-tier testing and C6 peptide ELISA) with respect to sensitivity and specificity were not statistically significant. CONCLUSIONS: Except in patients with erythema migrans, both test systems were sensitive for support of the diagnosis of Lyme disease. However, with current methods, 2-tier testing was associated with slightly better specificity.

Chronic inflammation and amyloidogenesis in Alzheimer's disease — role of Spirochetes.
University of British Columbia, Kinsmen Laboratory of Neurological Research, Vancouver, BC, Canada. email@example.com
Alzheimer's disease (AD) is associated with dementia, brain atrophy and the aggregation and accumulation of a cortical amyloid-beta peptide (Abeta). Chronic bacterial infections are frequently associated with amyloid deposition. It had been known from a century that the spirochete Treponema pallidum can cause dementia in the atrophic form of general paresis. It is noteworthy that the pathological hallmarks of this atrophic form are similar to those of AD. Recent observations showed that bacteria, including spirochetes contain amyloidogenic proteins and also that Abeta deposition and tau phosphorylation can be induced in or in vivo following exposure to bacteria or LPS. Bacteria or their poorly degradable debris are powerful inflammatory cytokine inducers, activate complement, affect vascular permeability, generate nitric oxide and free radicals, induce apoptosis and are amyloidogenic. All these processes are involved in the pathogenesis of AD. Old and new observations, reviewed here, indicate that to consider the possibility that bacteria, including several types of spirochetes highly prevalent in the population at large or their persisting debris may initiate cascade of events leading to chronic inflammation and amyloid deposition in AD is important, as appropriate antibacterial and antiinflammatory therapy would be available to prevent dementia.

O.U. Neurology, Ca' Foncello Hospital, Piazza Ospedale 1, 31100, Treviso, Italy.
Bannwarth's syndrome is a tick-transmitted neurological disease caused by spirochetes of the Borrelia burgdorferi group. Neurological manifestations of the disease occur after skin erythema and include: neuritic pain, lymphocytic pleocytosis without headache and sometimes cranial neuritis. We present the case of a man who complained of a neurological syndrome without evidence of tick bite and concurrent manifestation of the infection, for whom serological analysis only revealed the infection after testing repetitive specimens. We discuss the need to start early therapy when clinical manifestations are suggestive of the disease in endemic areas.

BACKGROUND: Lyme borreliosis is a MULTISYSTEM: tick-borne infection caused by the spirochete Borrelia burgdorferi. We present a survey of clinical stages, diagnosis, treatment and prognosis of Lyme borreliosis in adults. MATERIAL AND METHODS: The article is based on literature retrieved through database searches and own experience. RESULTS AND INTERPRETATION: In Norway, Lyme borreliosis is most prevalent in coastal areas from the south and up to Tr�ndelag. Lyme disease can be classified into three stages; localised stage, and early and late disseminated stages. A laboratory gold standard does not exist, so the diagnosis is based on a combination of clinical manifestations and indirect detection of the bacteria, most often specific antibodies. Antibody results must be interpreted with caution. No medication is needed after a tick bite, but all manifestations of Lyme borreliosis should be treated with antibiotics according to guidelines. The prognosis is generally good. Post Lyme disease with persistent symptoms after borreliosis is a controversial condition. No studies have demonstrated persistent infection with borrelia bacteria in patients with chronic complaints after adequate antibiotic treatment, and additional antibiotic treatment does not improve quality of life in these patients.

Lyme disease: European perspective.
Stanek G, Strle F.
Medical University of Vienna, Clinical Institute of Hygiene and Medical Microbiology, Vienna, Austria. email@example.com
The main clinical features of Lyme borreliosis seem to be the same in Europe and North America; however, the course of erythema migrans is distinct, with multiple erythema migrans and hematogeneous dissemination in early Lyme borreliosis less frequently observed in Europe. Moreover, the skin manifestations borrelial lymphocytoma and acrodermatitis chronica atrophicans are apparently European phenomena. Meningoradiculoneuritis in Lyme neuroborreliosis, with its severe radicular pain, is more prominent in Europe. Similar difficulties exist on both sides of the Atlantic with the serologic diagnosis of Lyme borreliosis.

Nervous system Lyme disease.
Department of Neurosciences, Atlantic Neuroscience Institute & Overlook Hospital, Summit, NJ 07902, USA. email@example.com
Lyme disease affects the nervous system in about 10% to 15% of infected individuals, most commonly causing lymphocytic meningitis. Cranial neuropathies, particularly facial nerve palsy, also occur frequently. Figuring prominently in the European literature, but less emphasized in the United States, is painful radiculitis, radicular pain involving a limb or trunk dermatome. Treatment of neuroborreliosis is usually straightforward; oral antibiotics may suffice in many patients. In severe cases, 2 to 4 weeks of parenteral therapy is necessary. All available evidence indicates that treatment of more than 4 weeks' duration carries substantial risk but minimal if any additional benefit.

Department of Family Medicine, Mayo Clinic, 13400 E Shea Blvd, Scottsdale, AZ 85259, USA.
Lyme disease is the most common tick-borne disease in the United States. This review details the risk factors, clinical presentation, treatment, and prophylaxis for the disease. Information was obtained from a search of the PubMed and MEDLINE databases (keyword: Lyme disease) for articles published from August 31, 1997, through September 1, 2007. Approximately 20,000 cases of Lyme disease are reported annually. Residents of the coastal Northeast, northwest California, and the Great Lakes region are at highest risk. Children and those spending extended time outdoors in wooded areas are also at increased risk. The disease is transmitted to humans through the bite of the Ixodes tick (Ixodes scapularis and Ixodes pacificus). Typically, the tick must feed for at least 36 hours for transmission of the causative bacterium, Borrelia burgdorferi, to occur. Each of the 3 stages of the disease is associated with specific clinical features: early localized infection, with erythema migrans, fever, malaise, fatigue, headache, myalgias, and arthralgias; early disseminated infection (occurring days to weeks later), with neurologic, musculoskeletal, or cardiovascular symptoms and multiple erythema migrans lesions; and late disseminated infection, with intermittent swelling and pain of 1 or more joints (especially knees). Neurologic manifestations (neuropathy or encephalopathy) may occur. Diagnosis is usually made clinically. Treatment is accomplished with doxycycline or amoxicillin; cefuroxime axetil or erythromycin can be used as an alternative. Late or severe disease requires intravenous ceftriaxone or penicillin G. Single-dose doxycycline (200 mg orally) can be used as prophylaxis in selected patients. Preventive measures should be emphasized to patients to help reduce risk.

Department of Clinical Chemistry, Kalmar County Hospital, Kalmar, Sweden. firstname.lastname@example.org
The aim of this study was to evaluate the usefulness of borrelia serology (Quick ELISA C6 Borrelia assay kit) as a diagnostic tool in cases of suspected neuroborreliosis. A retrospective patient material consisting of 124 paired serum and cerebrospinal fluid samples with a positive anti-borrelia antibody index (AI) using the IDEIA Lyme Neuroborreliosis test was compared with 124 AI-negative matched control subjects. The patients were divided into four groups based on presence of pleocytosis and age above or below 12 years. The presence of positive C6 serology in AI-positive patients with pleocytosis was 89% (83/93), significantly different (p<0.01) from in patients without pleocytosis (58%, 18/31). In AI-positive patients aged > or =12 years with pleocytosis, 94% (51/54) had a positive C6 serology. Of AI-positive patients with a symptom duration of more than 30 days, 93% (27/29) were positive by the C6 test. We conclude that the C6 serum test, together with clinical evaluation, is a powerful diagnostic tool in adult (> or =12 years) European patients with suspected neuroborreliosis with a symptom duration of more than 30 days. Patients with suspected neuroborreliosis and positive C6 results should be further investigated by lumbar puncture for definite diagnosis.

BACKGROUND: Neurological symptoms develop in 10-20% of children with borreliosis. AIM OF THE STUDY: It was a presentation of clinical manifestation of neuroborreliosis in children. MATERIAL AND METHODS: Children with neuroborreliosis and other neurological diseases were admitted to the University Hospital during 2005-2006 without any selection. Of these 9 patients, there were seven males and two females, ranging in age between 3-17 years. Neurological diagnostic was performed using ELISA Biomedica kit and western blot bands. A 2-6 week sequential treatment with either i.v. ceftazidime or amoxicillin and oral doxycycline or amoxicillin was provided. Children were monitored regularly during the next 4-24 months. RESULTS: The 9 children with borreliosis constitute 0.53% of the pediatric neurology department's patients. The clinical manifestation of LD were usual and unusual from patient to patient. They included three cases of facial nerve paralysis (with bilateral paralysis in one case). In two cases, they included transverse myelitis and in a single case, hemiparesis, meningitis and acute ataxia. Typically, other patients with early stage borreliosis first manifest focal seizures, raising the suspicion that borreliosis could be responsible for triggering seizures. The antibiotic treatment was successful in 7 patients and only partially effective in 2 children with facial nerve paralysis. CONCLUSIONS: The most common symptom of neuroborreliosis in children is motor dysfunction. Acute ataxia may be a clinical presentation of neuroborreliosis. It is probable that borreliosis_triggers seizures in children with EEG abnormalities.

Herpes zoster is a disease which occurs secondary to the reactivation of varicella-zoster virus. Motor involvement in acute herpes zoster is rare. We report a case of sciatica L5 due to herpes zoster infection with motor loss. Typical skin lesions occurred one week before the sciatica. Radiological finding did not explain the paresis. The diagnosis of zoster sciatica with motor involvement was suspected. Serological tests and cerebrospinal fluid examination established the diagnosis. The antiviral and physical treatment was conducted in order to improve functional outcome.

Viliuisk encephalomyelitis (VE) is an endemic neurological disease in Northeastern Siberia and generally believed to be a chronic encephalomyelitis of unknown origin. We investigated 17 patients with a clinical diagnosis of VE within the Viliuiski region of Sakha (Yakutian) Republic to explore the core clinical syndrome of chronic VE and subsequently whether VE is caused by Borrelia burgdorferi infection. We found a chronic myelopathy as the core of the syndrome, often following an acute phase with a meningo-radiculo-neuropathy, suggestive of chronic neuroborreliosis. A search for inflammatory parameters in a larger cohort in blood (39 VE patients and 41 controls) and CSF samples (10 VE patients and 7 controls) excluded an ongoing chronic infection, but revealed evidence for an immunological scar or a chronic inflammatory ("autoimmune") response in the CSF. In addition, we detected signs of a previous exposure to Borrelia burgdorferi antigens in a subset of chronic VE patients with positive serological results using ELISA/immunoblot in 54/10% and 22/0% of VE patients and controls, respectively (p values of 0.003/0.034; Fisher's exact test). However, CSF analyses did not show a link between exposure or at least immunological reaction against Borrelia and the risk of suffering from VE. Our data provide the first evidence of the presence of Borrelia burgdorferi or similar pathogens in Northeastern Siberia, but do not support a causative role of these pathogens in the aetiopathogenesis of VE.

Erratum in: J Neurol. 2008 May;255(5):782.
Recent studies have suggested a diagnostic role of the B-lymphocyte attracting chemokine (CXCL13) in the cerebrospinal fluid (CSF) in Lyme neuroborreliosis (LNB). Our aim was to evaluate diagnostic accuracy of CSF CXCL13 in a cohort of 59 consecutive patients referred to hospital for suspected LNB. Thirty-seven patients were classified as definite LNB and used as the reference standard. Seven were classified as probable, and seven as possible LNB. Eight patients did not fulfil case definitions and were used as controls. At presentation, CSF CXCL13 was elevated in all patients with definite LNB, as compared to a positive CSF B. burgdorferi (Bb) antibody index (AI) in 33 of 37. Pre-treatment sensitivity of elevated CSF [corrected] Bb Al [corrected] was 100 % (95 % CI = 91-100) and 89 % [corrected] (95 % CI = 75-96) respectively (p = 0.053). Among the eight control patients, CSF CXCL13 was normal in five and only slightly elevated in three, and Bb AI was negative in five. Specificity of CSF CXCL13 and Bb AI was similar 63 % (95 % CI = 31-86) (p = 1.0).CSF CXCL13 was elevated in 6/7 patients with probable LNB and 3/7 patients with possible LNB. Bb AI was negative in all these 14 patients. An additional control group consisted of 31 patients with multiple sclerosis (MS), 11 with non-inflammatory neurological diseases, and ten with verified non-Lyme meningitis and high CSF cell count. CSF CXCL13 was slightly elevated in 15 MS patients, and in nine meningitis patients. Mean CSF CXCL13 was higher in definite LNB (3524 ng/g CSF protein) than in MS (27 ng/g) and non-Lyme meningitis (23 ng/g) (p < 0.001). Four months post-treatment CSF CXCL13 was normalized in 82 % of patients with definite LNB, as compared to a negative Bb AI in 10 % (p < 0.001).CSF CXCL13 may be a useful supplement in early diagnosis of acute LNB.

Although Lyme borreliosis is increasingly diagnosed in the United Kingdom, few systematic studies have been performed there. UK data suggest that the commonest complications are neurological, but inadequate information exists about their nature and the incidence of late neuroborreliosis. Local data are necessary because clinical presentations may show geographical variation. This study aimed to provide data on clinical manifestations in an area of South West England and to estimate treatment delay. We reviewed clinical records of 88 patients in the Royal Devon and Exeter Hospital catchment area who had positive Borrelia antibody tests during a 5-year period. Fifty-six (64%) reported tick bites. The commonest presentations were erythema migrans (65%) and arthralgia/myalgia (27%). However, 22 patients (25%) had neurological symptoms other than headache alone. Fourteen had facial palsy, eight had confusion/drowsiness, four had meningism, five had radiculopathy, two had sixth nerve palsies, and two had peripheral neuropathies. No late, progressive or atypical neurological syndromes were found. Neurological manifestations were generally predictable and usually included either (or all) of meningoencephalitis, facial palsy or radiculopathy.

Laboratory of Reference for Cerebrospinal Fluid and Neuroimmunology, Homolka Hospital, 150 30 Prague, Czechia. email@example.com
Sixty-five samples of cerebrospinal fluid (CSF) were evaluated using an automated cytoflow method with the CD-Sapphire hematology analyzer in order to investigate possible relationships between cell population patterns and diagnostic groups and better understand the biology of neurological disease. A basic panel of CD markers, including CD3/4/8/19/138/HLA-DR, was used to analyze CSF samples from clinical and laboratory confirmed cases of multiple sclerosis, neuroborreliosis, viral and bacterial neuroinfective diseases, malignant infiltrations of meninges and scavenger macrophagic reactions of the central nervous system. The principles of immune response and the contribution of cytological 'disease-related patterns' for these nosological entities are described. The distinct patterns of lymphocyte subpopulations in neuroborreliosis appear to be characteristic and could possibly serve as diagnostic indicators. Further verification and research will be necessary to clarify the significance and nature of CD4+ CD8+ positive subset in cerebrospinal fluid.

Although many years have passed since Borrelia burgdorferi was first identified, advances in understanding biology and clinical course of infection made and new diagnostic procedures developed, Lyme disease is still difficult to diagnose. Therefore, it is often wrongly diagnosed and unnecessarily treated. In this paper we analyzed the latest data on Lyme disease diagnostic methods, paying much attention to their limitations and correct interpretation of results. In routine diagnosis of this diseases, indirect tests, based on the detection of specific IgM and IgG antibodies, are most useful. The Lyme disease diagnosis should begin with screening tests, which are highly sensitive but not specific enough and sometimes yield false positive results, then all positive results should be verified by confirmation tests, which allow to distinguish between true positive results and healthy individuals with false positive ones.

We describe a follow-up in a 15-year-old boy with neuroborreliosis diagnosed by clinical symptoms, CSF and serum analysis. MRI revealed a thalamic lesion and an enhancement of the right trigeminal nerve clinically associated with mild hypasthesia in the right maxillary region. Both, clinical symptoms and radiological findings disappeared within 2 months after treatment. Borrelia burgdorferi specific IgM and IgG in CSF and IgG in serum became negative between 6 and 12 months after diagnosis. We show that neuroborreliosis at an early stage may present only with moderate neurological deficits and that at this stage MRI reveals distinct cerebral lesions which might even precede clinical manifestation. Thus, early diagnosis and treatment of neuroborreliosis may prevent persistent neurologic lesions.

Borrelia burgdorferi sensu stricto and B. afzelii, but not B. garinii, are able to escape complement attack by binding factor H via OspE proteins. Recent finding of ospE genes also in B. garinii isolates has raised the question whether, under in vivo-conditions, B. garinii also expresses OspE proteins and consequently induces an antibody response. We set up an IgG ELISA by using recombinant OspE as an antigen. Sixty percent of acute and 64% of convalescent 25 erythema migrans patient samples were positive for anti-OspE antibodies. Anti-OspE antibodies were also found in the sera (83.6%) and cerebrospinal fluids (36%) of patients with neuroborreliosis. Since B. garinii is the major causative agent of neuroborreliosis, the result suggests that OspE is expressed by B. garinii in vivo. Of the 10 acrodermatitis chronica atrophicans patients, 80% had anti-OspE antibodies. Anti-OspE antibody positive sera inhibited factor H binding to Borrelia more efficiently than normal control sera (65% vs. 33.7%). Our results indicate that Borrelia spirochetes, including B. garinii, can induce the production of anti-OspE antibodies. This implies that OspE protein is produced in vivo by B. garinii possibly enabling it to escape complement and cause a CNS infection.

PURPOSE: The aberrant inflammatory response is probably involved in the pathogenesis of chronic Lyme borreliosis, including chronic Lyme arthritis and neuroborreliosis. Transforming growth factor-beta 1 (TGF-beta1) is an important anti-inflammatory and immunomodulatory cytokine and its deficient synthesis is linked to exaggerated inflammation and immune response. MATERIAL AND METHODS: Peripheral blood mononuclear cells (PBMC) from 25 patients with Lyme borreliosis and 6 controls were incubated for 7 days with suspension of Borrelia afzeli, B. garinii and B. burgdorferi sensu stricto spirochetes. TGF-beta1 concentration in culture supernatants was measured with ELISA. Results were analyzed according to disease duration (group I--chronic borreliosis, n=20; group II--early borreliosis, n=5) and clinical form (LA--arthritis, NB--neuroborreliosis). RESULTS: TGF-beta1 concentration was increased in supernatants of PBMC cultures of patients with early neuroborreliosis, in comparison with chronic borreliosis and controls. In chronic, but not in early borreliosis, there was a tendency for decrease of TGF-beta1 synthesis under stimulation with B. burgdorferi spirochetes. CONCLUSIONS: Impaired synthesis of TGF-beta1 by mononuclear cells seems to be present in patients with chronic forms of Lyme borreliosis when compared to those with early stage of the disease. It may be a factor contributing to the persistence of inadequate inflammatory response in patients in whom chronic form of the disease develops.

OBJECTIVE: To investigate the role of transcranial magnetic stimulation (TMS) to differentiate between idiopathic facial nerve palsy (iFNP) and facial nerve palsy due to borreliosis (bFNP). PATIENTS AND METHODS: Transcranial and intracanalicular magnetic and peripheral electrical stimulation of the facial nerve together with clinical grading according to the House and Brackmann scale were performed in 14 children and adolescents with facial palsy (median age 11.5 yr, range 4.6-16.5 yr). Serum and cerebrospinal fluid (CSF) were evaluated for antibodies against Borrelia burgdorferi and CSF cell count, glucose and protein content were screened with methods of routine laboratory testing. Data of patients were compared with normal values established in 10 healthy subjects (median age 10.2 yr, range 5.1-15.3 yr). RESULTS: Patients with iFNP showed a significant decrease in MEP amplitude to canalicular magnetic stimulation compared with healthy controls (p=0.03). However, MEP amplitude did not discriminate sufficiently between the two groups, because the ranges of dispersion of MEP amplitudes overlapped. Patients with bFNP had normal MEP amplitudes to canalicular magnetic stimulation compared with normal subjects. CONCLUSION: Diagnostic assessment by TMS failed to provide a reliable diagnostic criterion for distinguishing between iFNP and bFNP in children and adolescents.

We report on a 11-year-old boy who had 2 acute hemiparesis episodes over a period of 1 month. He suffered from headache and fatigue since 1 year. He could not remember neither a tick bite nor a local erythematous skin lesion. The diagnosis of neuroborreliosis was based on intrathecal production of specifics antibodies. Furthermore, the CSF/blood glucose ratio was decreased (0.14), which was rarely described. Cranial MRI showed left capsulothalamic inflammation and a vasculitis. The patient was successfully treated by ceftriaxone. Neuroborreliosis should be considered in all children with stroke-like episode, even in the absence of a history of a tick bite.

The pathogenesis of lyme neuroborreliosis: from infection to inflammation.
Rupprecht TA, Koedel U, Fingerle V, Pfister HW.
Department of Neurology, Ludwig-Maximilians University, Munich, Germany.
This review describes the current knowledge of the pathogenesis of acute Lyme neuroborreliosis (LNB), from invasion to inflammation of the central nervous system. Borrelia burgdorferi (B.b.) enters the host through a tick bite on the skin and may disseminate from there to secondary organs, including the central nervous system. To achieve this, B.b. first has to evade the hostile immune system. In a second step, the borrelia have to reach the central nervous system and cross the blood-brain barrier. Once in the cerebrospinal fluid (CSF), the spirochetes elicit an inflammatory response. We describe current knowledge about the infiltration of leukocytes into the CSF in LNB. In the final section, we discuss the mechanisms by which the spirochetal infection leads to the observed neural dysfunction. To conclude, we construct a stringent concept of the pathogenesis of LNB.

The results of the research already done, suggest an important role of selectins in inflammatory process of various etiology. Lack of selectins or their ligands causes severe complications, such as chronic inflammatory processes. The aim of this study was to analyze the role of selectins sL, sE and sP in the development and course of neuroborreliosis in the form of meningitis. We have also analyzed the influence of treatment on changes of selectins' concentration in serum and cerebrospinal fluid. MATERIAL AND METHODS: We have analyzed 17 patients with neuroborreliosis presenting as meningitis, in whom we measured by immunoenzymatic method concentration of selectins sL, sP and sE in blood and cerebrospinal fluid before and after 4-week therapy with cefotaxim. We used Human sL-selectin, Human sE-selectin and Human sP-selectin kits produced by Bender Med. Systems, Austria. Control group for measurement of concentration of selectins in serum consisted of 8 healthy patients. Control group for measurement of concentration of selectins in cerebrospinal fluid consisted of 8 patients, in whom lumbar puncture excluded inflammatory disease of the central nervous system. RESULTS: In serum concentration of selectins sL and sP was significantly higher comparing to control group. After treatment concentration of these selectins decreased, but still was significantly higher than in control group. Only concentration of selectin sE was significantly lower than in control group and after treatment decreased further remaining lower comparing to control group. In cerebrospinal fluid concentration of selectin sL was significantly higher comparing to control group and increased after treatment. Concentration of selectins sE and sP increased before treatment and decreased after treatment, but still remained elevated comparing to control group. CONCLUSIONS: Persistence of increased concentration of selectins sP and sL in serum and also of selectin sE in cerebrospinal fluid in patients with neuroborreliosis after completed antibiotic therapy and regression of clinical symptoms can suggest permanence of chronic inflammatory state in consequence of survival of B. burgdorferi spirochetes in affected tissues.

In this study we have developed a new Restriction-Fragment-Length-Polymorphism (RFLP) genotyping method for rapid detection and identification of Borrelia genospecies present as unique species or as co-infection in multiple specimens obtained simultaneously from 29 individual patients affected by early or late Lyme borreliosis (LB). The target of the RFLP-genotyping was the heterogeneous plasmid located ospA gene, thus we developed a method able to detect and differentiate between six clinically relevant Borrelia genospecies circulating in Europe, B. burgdorferi sensu stricto, B. garinii, B. afzelii, B. valaisiana, B. bissettii and B. spielmanii. In this study Borrelia DNA could be detected by PCR in at least one specimen of each patient, except in one case of neuroborreliosis (NB); blood samples gave the highest sensitivity in all patient groups. The genotyping indicated that B. afzelii was present in 8 patients with skin involvement, B. garinii in 2 cases of NB and 4 cases with skin involvement, B. burgdorferi sensu stricto was detected in one patient with skin involvement and another with Lyme arthritis. Different Borrelia species in distinct specimens were identified in one patient with EM. The RFLP analysis of 11 patients revealed mixed patterns, which suggested pluri-infection with different Borrelia species.

Klinik f�r Neurologie, Johann-Wolfgang-Goethe-Universit�t, Schleusenweg 2-16, 60528, Franfurt am Main, Deutschland.
A 19-year-old immune-competent patient developed right-sided headache and, subsequently, subacute diplopia. On clinical examination he had incomplete right oculomotor palsy. Cranial MRI showed pathologic contrast enhancement of the right oculomotor nerve at its exit point from the mesencephalon, and the CSF displayed slight pleocytosis. The following relevant differential diagnoses were not supported by additional examinations: neurosarcoidosis, Lyme neuroborreliosis, neurosyphilis, tuberculous meningitis, viral meningitis (HIV, VZV, CMV), CNS lymphoma, vasculitis associated with rheumatic disease, Tolosa-Hunt syndrome, and diabetic neuropathy. However, on the basis of blood lymphocytosis, positive heterophile antibody test (Paul-Bunnell test), the presence of IgM antibodies against Epstein-Barr virus capsid antigen, and elevated transaminases, infectious mononucleosis was diagnosed. Isolated neuritis of the oculomotor nerve is a rare parainfectious manifestation of infectious mononucleosis.

[Borreliosis as the cause of disability pensions in Norway]
[Article in Norwegian]
Reiso H, Brage S.
Helse-nettverket, Arendal kommune, Serviceboks 650, 4809 Arendal. firstname.lastname@example.org
BACKGROUND: Borreliosis is a bacterial infection transferred by tick-bites. Neuroborreliosis is the most frequent disseminated form of the disorder in Norway. Registers exist in Norway on all reported communicable diseases (The Norwegian Surveillance System for Communicable Diseases [MSIS]) and disability pension diagnoses (The Norwegian Directorate of Labour and Welfare). MATERIAL AND METHODS: Geographic distributions of borreliosis and changes over time are presented. Disability pensions (coded by International Classification of Diseases [ICD]) in the period 1998-2005, in which borreliosis was used as the primary or secondary diagnosis (ICD-10), were compared with MSIS-data for borreliosis on municipal and county levels. RESULTS: Borreliosis was the cause of disability pensions in 55 cases. The Vestfold and Agder counties had the highest number of cases. Larvik municipality had 9 cases, Arendal had four and Kristiansand had nine cases. The annual rates of new disability pensions caused by borreliosis were low but increasing in the period 1998-2005. The disability pension rates tended to reflect changes in the number of MSIS-reported cases, with pensions changing 1-2 years after MSIS-changes. Most MSIS-reported cases are in the Agder and Telemark counties. INTERPRETATION: Disability pension are rarely caused by borreliosis. The annual incidence of disability pensions seems to reflect the number of MSIS-reported cases of borreliosis. The Agder and Vestfold counties have the highest incidence.

THE AIM OF THE STUDY: To evaluate the frequency of clinical forms as well as laboratory and neuroimaging results of patients with diagnosed neuroborreliosis in the years 2000-2005 due to neuroborreliosis. MATERIAL AND METHODS: The records of 125 patients at the age of 21-83 (mean 49 years) treated in the years 2000-2005 in the Department of Infectious Diseases and Neuroinfections, Medical University, Bialystok were subject to retrospective analysis. Diagnosis was based on case history along with a clinical picture and presence of antibodies against Borrelia burgdorferi, using ELISA test (Borrelia IgM and Borrelia IgG recombinant Biomedica). The subject of the detailed analysis was demographic data, clinical symptoms as well as subjective complaints, results of neurological examinations, the results of cerebrospinal fluid (CSF) parameters and results of serologic tests. RESULTS: The most frequent clinical symptoms observed were: headaches 71%, vertigo 44%, meningeal symptoms 22% and neurological paresis 27% (including facial palsy--23%). Inflammatory changes in CSF in the form of increased proteins concentration and pleocytosis were present among 34% of patients. In all cases the antibodies against B. burgdorferi were present in CSF in diagnostically significant titer. Serum presence of antibodies antiborrelia IgM was found with 55% of patients and anibodies antiborrelia IgG with 76% of patients. 17% of patients suffering from neuroborreliosis were also coinfected with tick-borne encephalitis virus. Along with the neurological symptoms, which were crucial to diagnosis, general symptoms coexisted, such as: weakness 35%, arthralgia 54% and nausea 17%. In the analyzed period of time neuroborreliosis was diagnosed in a 13% of hospitalized patient suffering from borreliosis. CONCLUSIONS: Absence of erythema migrans does not exclude existence of neuroborreliosis. Symptoms that may suggest presence of neuroborreliosis are not only neurological symptoms such as facial palsy, but also memory and concentration disorders and general symptoms.

INTRODUCTION: Acute myelitis accounts for 4 to 5 percent of all cases of neuroborreliosis. In the literature, simultaneous spinal MRI and cerebrospinal fluid (CSF) investigations are presented for only 8 cases. We describe here 3 cases of acute Lyme myelitis. METHOD: In a cohort of 45 patients with neuroborreliosis, diagnosed between January 1998 and January 2005, 3 had acute myelitis. Clinical, biological and radiological data were studied. CASE REPORTS: The three patients had motor, sensorial and sphincter involvement. Extra-spinal involvement, such as fever and headache for one, facial nerve palsy for the second and subarachnoid hemorrhage for the third, was also noted. Pleocytosis varied from 10 to 520 white cells per mm3. Lyme serology was positive in CSF for all. Intrathecal anti-Borrelia antibody index was positive or intermediate for all three patients. Spinal cord MRI revealed a large hyperintense zone involving more than 3 vertebral segments. Myelitis was central, posterior or transverse in the axial plane. The clinical course was favorable after a three-week course of appropriate antibiotics. CONCLUSION: These 3 cases and the others from the literature show the diversity of the clinical and radiological features of acute myelitis: transverse, central or posterior myelitis. Thus, Lyme serology in CSF in indicated for patients presenting acute myelitis, particularly in endemic areas.

Lyme disease in a patient with chronic lymphocytic leukemia mimics leukemic meningeosis.
Schweighofer CD, F�tkenheuer G, Staib P, Hallek M, Reiser M.
Department of Internal Medicine I, University of Cologne, Germany. firstname.lastname@example.org
BACKGROUND: Involvement of the central nervous system (CNS) is a rare complication of chronic lymphocytic leukemia (CLL) and seems to be more frequent in patients with Richter's syndrome or prolymphocytic transformation. Cases with leptomeningeal involvement reported in the literature mostly do not discuss the definition of CLL-associated meningeosis and the exclusion of neuroborreliosis. PATIENT AND METHODS: We present the case of a 75-year-old male patient who was admitted to a rural hospital with ataxia, disorientation, and signs of progressive CLL disease. He was diagnosed of suspicious meningeosis leukemica, and treatment was started with dexamethasone for leukemic CNS involvement. RESULTS: When referred to our center, careful immunophenotyping of the CNS lymphocytes as well as assessment for infectious causes of lymphocytic meningitis led to the diagnosis of Lyme disease/neuroborreliosis. An antibiotic regimen with ceftriaxone for 3 weeks resulted in complete remission of all symptoms. There was no need for CLL treatment. CONCLUSION: In conclusion, this case report should alert clinicians that lymphocytic meningeal involvement in CLL patients accounts for the rare leukemic meningeosis only if cerebrospinal fluid cells show a predominating immunophenotype of typical BCLL cells, i.e. by flow cytometry, and if any infectious cause including Lyme disease has been ruled out.

BACKGROUND: Optimal treatment remains uncertain for patients with cognitive impairment that persists or returns after standard IV antibiotic therapy for Lyme disease. METHODS: Patients had well-documented Lyme disease, with at least 3 weeks of prior IV antibiotics, current positive IgG Western blot, and objective memory impairment. Healthy individuals served as controls for practice effects. Patients were randomly assigned to 10 weeks of double-masked treatment with IV ceftriaxone or IV placebo and then no antibiotic therapy. The primary outcome was neurocognitive performance at week 12-specifically, memory. Durability of benefit was evaluated at week 24. Group differences were estimated according to longitudinal mixed-effects models. RESULTS: After screening 3368 patients and 305 volunteers, 37 patients and 20 healthy individuals enrolled. Enrolled patients had mild to moderate cognitive impairment and marked levels of fatigue, pain, and impaired physical functioning. Across six cognitive domains, a significant treatment-by-time interaction favored the antibiotic-treated group at week 12. The improvement was generalized (not specific to domain) and moderate in magnitude, but it was not sustained to week 24. On secondary outcome, patients with more severe fatigue, pain, and impaired physical functioning who received antibiotics were improved at week 12, and this was sustained to week 24 for pain and physical functioning. Adverse events from either the study medication or the PICC line were noted among 6 of 23 (26.1%) patients given IV ceftriaxone and among 1 of 14 (7.1%) patients given IV placebo; these resolved without permanent injury. CONCLUSION: IV ceftriaxone therapy results in short-term cognitive improvement for patients with posttreatment Lyme encephalopathy, but relapse in cognition occurs after the antibiotic is discontinued. Treatment strategies that result in sustained cognitive improvement are needed.

The antibody response of serum IgM and IgG of patients with neuroborreliosis and erythema migrans of Lyme borreliosis (LB) was examined against a 41-kDa flagellar antigen and an 8-mer synthetic OspC8 peptide (VAESPKKP) derived from the C-terminus of outer surface protein C (OspC) from Borrelia garinii. We developed a streptavidin-modified biochip-based immunodiagnosis and compared it with conventional methods such as enzyme-linked immunosorbent assay (ELISA) and Western blot (WB). The diagnostic sensitivity of the coated biochips was demonstrated to be identical, and the results of conventional assays such as ELISA and WB were confirmed. Flagellar antigens lead to better diagnosis because of a higher discriminative value. By contrast, OspC8, a peptide derived from the outer surface antigen, is less sensitive to identify immunity in LB. The inferior antigenicity of OspC8 may be due to epitope masking. Overall, this system is open to simultaneously analyze a larger family of peptides differing in length. Thus, an array approach is generally more advantageous to extend the pattern of antigens to be tested for antigenicity in LB. Serial analysis during ongoing disease may be valuable to learn more about the course of the disease and intermittent reactivation of infection. Protein biochip as a potential substitution of ELISA and WB method offers the opportunity to study serum immunity in a multiplicity of patients simultaneously.

BACKGROUND: No consensual criteria exist to diagnose neuroborreliosis. The intrathecal anti-Borrelia antibody index (AI) is a necessary criterion to diagnose neuroborreliosis in Europe, but not in the United States. Previous studies to determine the diagnostic value of the AI found a sensitivity ranging from 55% to 80%. However, these studies included only typical clinical cases of meningitis or meningoradiculitis, and none had a control group with CSF anti-Borrelia antibodies. METHODS: We studied a sample of 123 consecutive patients with clinical signs of neurologic involvement and CSF anti-Borrelia antibodies. We determined the AI for all patients and a final diagnosis was made. Patients were then divided into three groups (neuroborreliosis, possible neuroborreliosis, control). RESULTS: Thirty of the 40 patients with neuroborreliosis had a positive AI (AI sensitivity = 75%). Two of the 74 patients with another neurologic diagnosis had a positive AI (AI specificity = 97%). CONCLUSION: The antibody index has a very good specificity but only moderate sensitivity. Given the lack of consensual criteria for neuroborreliosis and the absence of a "gold standard" diagnostic test, we propose pragmatic diagnostic criteria for neuroborreliosis, namely the presence of four of the following five items: no past history of neuroborreliosis, positive CSF ELISA serology, positive anti-Borrelia antibody index, favorable outcome after specific antibiotic treatment, and no differential diagnosis. These new criteria will need to be tested in a larger, prospective cohort.

In Europe, Lyme borreliosis is the most common disease communicated by ticks and especially affects the skin, nervous system, joints, and heart. It is caused by at least four species of the spirochete Borrelia burgdorferi. The various pathologies are classified as early forms (erythema migrans, borrelia lymphocytom, early neuroborreliosis, carditis) or late forms (arthritis, acrodermatitis chronica atrophicans, chronic neuroborreliosis). The accuracy of serodiagnosis is 20-50% with erythema migrans, 70-90% with early neuroborreliosis, and nearly 100% with Lyme arthritis. Following special indications, the agent is confirmed by skin biopsy or spinal or joint puncture. Oral therapy is performed with amoxicillin, doxycycline, and cefuroxime, and intravenous therapy uses ceftriaxone, cefotaxime, or penicillin G. All in all, the prognosis of treated Lyme borreliosis is good. In childhood permanent defects are extremely rare, even following long-term manifestation at an early age.

BACKGROUND: Borrelia infections, especially chronic neuroborreliosis (NB), may cause considerable diagnostic problems. This diagnosis is based on symptoms and findings in the cerebrospinal fluid but is not always conclusive. PURPOSE: To evaluate brain magnetic resonance imaging (MRI) in chronic NB, to compare the findings with healthy controls, and to correlate MRI findings with disease duration. MATERIAL AND METHODS: Sixteen well-characterized patients with chronic NB and 16 matched controls were examined in a 1.5T scanner with a standard head coil. T1- (with and without gadolinium), T2-, and diffusion-weighted imaging plus fluid-attenuated inversion recovery (FLAIR) imaging were used. RESULTS: White matter lesions and lesions in the basal ganglia were seen in 12 patients and 10 controls (no significant difference). Subependymal lesions were detected in patients down to the age of 25 and in the controls down to the age of 43. The number of lesions was correlated to age both in patients (rho = 0.83, P<0.01) and in controls (rho = 0.61, P<0.05), but not to the duration of disease. Most lesions were detected with FLAIR, but many also with T2-weighted imaging. CONCLUSION: A number of MRI findings were detected in patients with chronic NB, although the findings were unspecific when compared with matched controls and did not correlate with disease duration. However, subependymal lesions may constitute a potential finding in chronic NB.

Lyme disease is a multisystem infectious disease with a wide variety of symptoms involving the skin as well as nervous, musculosceletal and cardiovascular systems. Lyme disease is caused by spirochaete Borrelia burgdorferi transmitted by Ixodes tics in endemic regions. The diverse manifestations of neuroborreliosis require it to be included in differential diagnosis of many neurological disorders. The paper reviews the spectrum of clinical symptoms of nervous system involvement in early and late Lyme disease.

The aim of this review was to analyze the current strategies of treatment and follow-up of disseminated and late Lyme borreliosis. A comprehensive search was performed using the Medline database. Only relevant reviews, expert guidelines and randomized controlled clinical trials were selected and, if necessary, open trials. Major drugs used in these studies were amoxicillin, doxycycline, penicillin G, and ceftriaxone. Oral administration of antibiotics was preferred in Lyme arthritis whereas parenteral drugs were mostly used in neuroborreliosis. The treatment duration usually ranged from 14 to 30 days. Prolonged antibiotic courses recommended by some authors in post-Lyme syndromes were not validated by several randomized placebo controlled studies. Follow up patterns were analyzed in order to determine possible prognosis parameters allowing to distinguih active Borrelia burgdorferi infection from a sequel of infection.

OBJECTIVE: Analysis of clinical picture in children hospitalized because of suspicion of neuroborreliosis and evaluation of usefulness of testing serum and cerebrospinal fluid (CSF) for specific antibodies. MATERIAL AND METHODS: 23 children (age: 13 months - 15.5 years) were hospitalized: 11 children with facial palsy, 2 children with radiculopathy and 10 children with headache. In 21 children lumbar puncture and CSF examination was done. Serum of all children and CSF of 21 children were tested by ELISA for specific antibodies (IDEIA DakoCytomation). RESULTS: Meningeal signs in physical examination were found in 4 children and inflammatory CSF changes in 8 children. Specific antibodies in sera of 19 children and in CSF of 7 children. Neuroborreliosis was diagnosed in 12 children: in 9 facial palsy (in 6 with inflammatory CSF changes), in 2 Bannwarth's syndrome and in 1 aseptic meningitis. Diagnosis was confirmed by detection of specific antibodies in sera of 10 children and in CSF of 6 children. CONCLUSIONS: Meningitis in the course of neuroborreliosis is not always accompanied by meningeal signs. Positive serology is not an unequivocal confirmation of neuroborreliosis especially if symptoms are nonspecific (e.g. headache).

Increased morbidity of viral tick borne encephalitis since the 90's indicates growing risk of Rother tick borne diseases, including neuroborreliosis. Analysis of demographical, epidemiological and clinical data of patients hospitalised in Departament on Infectious Diseases and Neuroinfections in years 2000-2005 revealed that among patients with Lyme disease 13% were with neuroborreliosis with broad spectrum of neurologic symptoms as cranial nerves paresis (mainly n.VII), as well concentration and memory disturbances, and general symptoms. Some of patiets did not recall tick bite and did not present earlier borreliosis symptoms. Imaging only supports recognitio.

Cerebrospinal fluid (CSF) and serum samples from 34 patients with proven neuroborreliosis (NB) and 22 patients with suspected neuroborreliosis (SNB) from Finland were analysed for antibodies to decorin-binding proteins A (DbpA) and B (DbpB). Antibodies to recombinant protein antigens originating from Borrelia burgdorferi sensu stricto, B. afzelii, or B. garinii species were studied by enzyme-linked immunosorbent assay (ELISA). Of the 34 patients with NB, 100% of the CSF and 88% of the serum samples had IgG antibodies to 1 to 3 variants of DbpA and 79% of the CSF and 70% of the serum samples were positive for 1 to 3 DbpB variants. Antibodies to DbpB seemed to be associated with lymphocytic pleocytosis in the CSF and short duration of the disease, whereas antibodies to DbpA in the CSF were observed irrespective of the duration of the disease and lymphocytic pleocytosis. Among the variant antigens, CSF reactivity was mainly with the DbpB from B. garinii, whereas positivity with the DbpA from B. afzelii or B. garinii predominated. The results suggest that CSF antibodies to DbpB might be useful as a marker of active infection whereas antibodies to DbpA seem to persist a long time after acute phases of NB.

[Concentrations of pro-inflammatory cytokines IFN-gamma, IL-6, IL-12 and IL-15 in serum and cerebrospinal fluid in patients with neuroborreliosis undergoing antibiotic treatment]
[Article in Polish]

Pathogenesis of Lyme disease, including neuroborreliosis, remains unclear. However, pro-inflammatory cytokines seem to be involved and might be used to monitor the course of the disease. It has been also shown that B. burgdorferi protects itself from elimination by modulating function of the host's immune system. THE AIM OF THIS STUDY: The purpose of this study was to evaluate the serum and cerebrospinal fluid (CSF) concentrations of selected cytokines in patients with neuroborreliosis and their change during antibiotic treatment. MATERIAL AND METHODS: The group of 25 patients was examined, all undergoing antibiotic therapy due to meningitis caused by Borrelia burgdorferi infection. The group included 10 (40%) females and 15 (60%) males in the mean age x = 42,3 years. The control group for serum measurements consisted of 25 healthy individuals (mean age x =43, 1) while control group for CSF study included 10 patients (aged x = 53,5 years) from whom CSF with normal parameters was taken during diagnostic procedures neurosurgical. We examined serum and CSF before and after antibiotics for concentrations of interferon-gamma (INF-gamma), interleukin-6 (IL-6), interleukin-12 (IL-12) and interleukin-15 (IL-15). RESULTS: In the first examination the significant increase of IFN-gamma, IL-6, IL-2, IL-15 serum and CSF concentration was detected in comparison to control group. After 4-weeks antibiotic treatment the concentrations of studied cytokines decreased significantly in serum as well as in CSF but remained increased in comparison with controls. CONCLUSIONS: Although antibiotic treatment leads to withdrawal of clinical symptoms of neuroborreliosis and normalization of CSF general parameters, pro-inflammatory cytokines' concentrations in serum and CSF remain elevated. It may be explained by the persistence of inflammatory conditions, perhaps related to surviving of a fraction of Borrelia burgdorferi spirochetes within CNS tissue. This phenomenon might lead to development of chronic CNS lesions.

The aim of the study was to examine diagnostic sensitivity and temporal course of intrathecal Borrelia burgdorferi (Bb) antibody production in acute Lyme neuroborreliosis (LNB). We recruited consecutive adult patients with LNB diagnosis based on strict selection criteria. Serum and cerebrospinal fluid (CSFs) were obtained, and clinical examination was performed pre-treatment, and 13 days and 4 months post-treatment. Pre-treatment positive Bb antibody index (AI) was detected in 34 of 43 (79%). All nine pre-treatment Bb AI negative patients, and 26 of 34 pre-treatment Bb AI positive patients reported symptom duration <6 weeks. Eight patients, all Bb AI positive, reported symptom duration of 6 weeks or longer. Consequently, pre-treatment diagnostic sensitivity of Bb AI was 74% when symptom duration was <6 weeks, and 100% when 6 weeks or longer. Three patients converted from negative to positive Bb AI status post-treatment. The six patients who were persistently Bb AI negative had lower CSF cell count and protein at presentation, when compared with the patients with positive Bb AI. In conclusion, the diagnostic sensitivity of Bb AI is suboptimal in acute early LNB. Repeated post-treatment Bb AI testing, to confirm or reject LNB diagnosis, is unreliable, as the majority of initial Bb AI negative patients remained negative at follow-up.

Division of Clinical Neurology, Lund University Hospital, Lund, Sweden. Bengt.B.Eriksson@skane.se
We describe a case of encephalopathy in which the clinical picture and triphasic waves in the EEG indicated a metabolic cause. However, the illness was caused by neuroborreliosis. The occurrence of triphasic waves in the EEG is a strong evidence of metabolic encephalopathy, but triphasic waves are not specific for metabolic encephalopathy. Triphasic waves have been described in a number of non-metabolic encephalopaties and structural brain lesions. To our knowledge, this is the first report of triphasic waves in Borrelia burgdorferi meningoencephalitis.

The symptoms of Lyme meningoradiculitis and the value of biological examinations in an endemic area were determined in a prospective study in which data were collected on all patients consecutively hospitalised for Lyme meningoradiculitis at our institution during an 18-month period. Specific antibody titres in the serum and cerebrospinal fluid (CSF) were determined by Vidas enzyme-linked-immunosorbent-assay (IgG + IgM), Dade-Behring enzyme immunoassay (EIA) (IgM; IgG) and Western blot analysis (IgG). We also searched for Borrelia burgdorferi in the CSF by PCR analysis and following culture on a specific medium. A control group was recruited, consisting of 16 consecutive patients who had been referred during the same period with suspected but not confirmed Lyme meningoradiculitis. Eleven patients were included. Borrelia EIA of the serum revealed that 40% of the patients had both elevated specific IgM titres and intrathecal synthesis of specific IgG; 40% of the patients was negative for IgM but had isolated intrathecal synthesis of IgG; 20% of the patients had elevated specific IgM titres without intrathecal synthesis of IgG. PCR analysis and the CSF culture were positive in one case only (B. garinii). The results of this study highlight the importance of systematic serological testing for B. burgdorferi in the CSF in the case of early neuroborreliosis suspicion, even in the absence of IgM serum antibodies, which was the case in 40% of the patients in the present study. Nevertheless, intrathecal anti-B. burgdorferi IgG synthesis, which remains the "gold standard" for the diagnosis of neuroborreliosis, was not detectable in 20% of the patients for whom diagnosis was subsequently confirmed by demonstration of specific serum IgM.

The purpose of this study was to evaluate the diagnostic sensitivity and specificity of a commercial C6 enzyme immuno assay, QuickC6, in acute Lyme neuroborreliosis (LNB) in endemic areas. Paired sera and cerebral spinal fluids (CSFs) from 60 patients with definite LNB, eight patients with possible LNB, 18 patients with conditions mimicking LNB and 42 persons with noninfectious neurological disease were examined. The case definition of LNB was based on strict criteria during a prospective 4-month follow-up. The sensitivity of QuickC6 was 98% both in sera and CSFs, and the diagnostic specificity was 61% in sera and 88% in CSFs. QuickC6 is a sensitive, simple and cost-effective screening test in serum and CSF in diagnosis of acute LNB. Specificity needs further evaluation.

Despite rather strict recommendations for antibiotic treatment of disseminated Lyme borreliosis (LB), evidence-based studies on the duration of antibiotic treatment are scarce. The aim of this multicenter study was to determine whether initial treatment with intravenous ceftriaxone (CRO) for 3 weeks should be extended with a period of adjunct oral antibiotic therapy. A total of 152 consecutive patients with LB were randomized in a double-blind fashion to receive either amoxicillin (AMOX) 1 g or placebo (PBO) twice daily for 100 days. Both groups received an initial treatment of intravenous CRO 2 g daily for 3 weeks, followed by the randomized drug or PBO. The outcome was evaluated using the visual analogue scale at the follow-up visits. The final analysis included 145 patients, of whom 73 received AMOX and 72 PBO. Diagnoses of LB were categorized as either definite or possible, on the basis of symptoms, signs, and laboratory results. The diagnosis was definite in 52 of the 73 (71.2%) AMOX-treated patients and in 54 of the 72 (75%) PBO patients. Of the patients with definite diagnoses, 62 had neuroborreliosis, 45 arthritis or other musculoskeletal manifestations, and 4 other manifestations of LB. As judged by the visual analogue scale and patient records, the outcome after a 1-year follow-up period was excellent or good in 114 (78.6%) patients, controversial in 14 (9.7%) patients, and poor in 17 (11.7%) patients. In patients with definite LB, the outcome was excellent or good in 49 (92.5%) AMOX-treated patients and 47 (87.0%) PBO patients and poor in 3 (5.7%) AMOX-treated patients and 6 (11.1%) PBO patients (difference nonsignificant, p = 0.49). Twelve months after the end of intravenous antibiotic therapy, the levels of antibodies against Borrelia burgdorferi were markedly decreased in 50% of the patients with definite LB in both groups. The results indicate that oral adjunct antibiotics are not justified in the treatment of patients with disseminated LB who initially receive intravenous CRO for 3 weeks. The clinical outcome cannot be evaluated at the completion of intravenous antibiotic treatment but rather 6-12 months afterwards. In patients with chronic post-treatment symptoms, persistent positive levels of antibodies do not seem to provide any useful information for further care of the patient.

Medizinische Poliklinik, Universit�tskinderklinik, Inselspital Bern.
A 6-year-old boy presented with deterioration of general well-being during several weeks, headache and swelling of lymph nodes in the neck. In addition, the parents reported brief episodes resembling typical absence seizures. Serological tests and the examination of cerebrospinal fluid revealed neuroborreliosis. At the same time, electroencephalography showed characteristic patterns of absence epilepsy. The boy's condition improved rapidly during a 2-week course of intravenous ceftriaxone and after initiation of antiepileptic therapy. To our knowledge, absence epilepsy has not previously been reported in association with neuroborreliosis. We consider the two conditions to be coincidental.

Borrelia garinii induces CXCL13 production in human monocytes through Toll-like receptor 2.

Recent studies have suggested an important role for the B-cell-attracting chemokine CXCL13 in the B-cell-dominated cerebrospinal fluid (CSF) infiltrate in patients with neuroborreliosis (NB). High levels of CXCL13 were present in the CSF of NB patients. It has not been clear, however, whether high CSF CXCL13 titers are specific for NB or are a characteristic of other spirochetal diseases as well. Furthermore, the mechanisms leading to the observed CXCL13 expression have not been identified yet. Here we describe similarly elevated CSF CXCL13 levels in patients with neurosyphilis, while pneumococcal meningitis patient CSF do not have high CXCL13 levels. In parallel, challenge of human monocytes in vitro with two of the spirochetal causative organisms, Borrelia garinii (the Borrelia species most frequently found in NB patients) and Treponema pallidum, but not challenge with pneumococci, induced CXCL13 release. This finding implies that a common spirochetal motif is a CXCL13 inducer. Accordingly, we found that the lipid moiety N-palmitoyl-S-(bis[palmitoyloxy]propyl)cystein (Pam(3)C) (three palmitoyl residues bound to N-terminal cysteine) of the spirochetal lipoproteins is critical for the CXCL13 induction in monocytes. As the Pam(3)C motif is known to signal via Toll-like receptor 2 (TLR2) and an anti-TLR2 monoclonal antibody blocked CXCL13 production of human monocytes incubated with B. garinii, this suggests that TLR2 is a major mediator of Borrelia-induced secretion of CXCL13 from human monocytes.

OBJECTIVE: To provide evidence-based recommendations on the treatment of nervous system Lyme disease and post-Lyme syndrome. Three questions were addressed: 1) Which antimicrobial agents are effective? 2) Are different regimens preferred for different manifestations of nervous system Lyme disease? 3) What duration of therapy is needed? METHODS: The authors analyzed published studies (1983-2003) using a structured review process to classify the evidence related to the questions posed. RESULTS: The panel reviewed 353 abstracts which yielded 112 potentially relevant articles that were reviewed, from which 37 articles were identified that were included in the analysis. CONCLUSIONS: There are sufficient data to conclude that, in both adults and children, this nervous system infection responds well to penicillin, ceftriaxone, cefotaxime, and doxycycline (Level B recommendation). Although most studies have used parenteral regimens for neuroborreliosis, several European studies support use of oral doxycycline in adults with meningitis, cranial neuritis, and radiculitis (Level B), reserving parenteral regimens for patients with parenchymal CNS involvement, other severe neurologic symptomatology, or failure to respond to oral regimens. The number of children (> or =8 years of age) enrolled in rigorous studies of oral vs parenteral regimens has been smaller, making conclusions less statistically compelling. However, all available data indicate results are comparable to those observed in adults. In contrast, there is no compelling evidence that prolonged treatment with antibiotics has any beneficial effect in post-Lyme syndrome (Level A).

Pathogen specificity and autoimmunity are distinct features of antigen-driven immune responses in neuroborreliosis.

Neuroborreliosis (NB) is a chronic infectious disease of the central nervous system (CNS) caused by a tick-borne spirochete, Borrelia burgdorferi. In addition to direct effects of the causative infectious agent, additional immunity-mediated mechanisms are thought to play a role in the CNS pathology of NB. In order to further understand the involvement of humoral immune mechanisms in NB, we dissected the intrathecal antibody responses down to the single-plasma-cell level. Starting with single-cell reverse transcription-PCR of fluorescence-activated cell sorter-sorted cerebrospinal fluid plasma cells from an NB patient, we identified expanded clones and resurrected the antigen specificity of their secreted antibodies through recombinant expression of the correctly paired immunoglobulin heavy- and light-chain genes as monoclonal antibodies (MAbs). As expected, we found specificity for the causative infectious agent, B. burgdorferi, among the clonally expanded plasma cell (cePC)-derived MAbs. However, from an independent cePC of the same patient, we could derive MAbs specific for human CNS myelin, without detectable cross-reactivity with B. burgdorferi antigens. While reactivity against B. burgdorferi is a known feature of humoral immune responses in NB, we show (i) that immune responses specific for self antigens may be a distinct feature of CNS infections independent of pathogen reactivity and (ii) that humoral autoimmunity in NB (since found in cePC) is the result of a truly antigen-driven immune response. Our findings indicate that in NB mechanisms may be at play that induce distinct immune responses specific for pathogen and self antigens independent from "molecular mimicry."

[Role of biological assays in the diagnosis of Lyme borreliosis presentations. What are the techniques and which are currently available?]

The biological diagnosis of Borrelia burgdorferi sensu lato infection is usually made by antibody detection in patient sera. Thus, serological testing (Elisa, immunoblotting) is essential for a biological diagnosis. Specific antibody detection is usually done in serum and CSF of patients suspected of Lyme borreliosis. Laboratories must follow European recommendations to validate these assays in routine practice. Antibody detection lacks sensitivity in the early cutaneous phase of the infection. Therefore, serological testing is not recommended for the diagnosis of erythema migrans. The interpretation of serology must take into account the variability of Elisa sensitivity and specificity and the lack of standardization for Western-blotting in Europe. Besides these indirect diagnosis techniques, there is also direct detection of spirochetes by culture or by in vitro DNA amplification but these require adequate samples. These molecular tests must not be performed routinely, but only for specific clinical situations and in specialized laboratories only.

Lyme neuroborreliosis (LNB), the neurological manifestation of systemic infection with the complex spirochaete Borrelia burgdorferi, can pose a challenge for practising neurologists. This Review is a summary of clinical presentation, diagnosis, and therapy, as well as of recent advances in our understanding of LNB. Many new insights have been gained through work in experimental models of the disease. An appreciation of the genetic heterogeneity of the causative pathogen has helped clinicians in their understanding of the diverse presentations of LNB.

Leukemic involvement of the central nervous system (CNS) in previously undiagnosed chronic lymphocytic leukemia (CLL) is very rare. We report the case of a 62-year-old man with neuroborreliosis in which cytologic, immunocytochemical, and flow cytometry analyses revealed the presence of clonal B-lymphocytes in the cerebrospinal fluid (CSF). After the patient received antimicrobial therapy, his meningeal symptoms cleared up, and the number of cells in the CSF decreased. Monoclonal lymphocytes were still detectable at the same percentage, however, despite systemic chlorambucil therapy. The application of intrathecal dexamethasone therapy led to the disappearance of B-cell CLL (B-CLL) cells in the CSF. We presumed that the neuroborreliosis enabled the transmigration of leukocytes, including B-CLL cells, across the blood-brain barrier via activation of matrix metalloproteinase 9, an enzyme known to open the blood-brain barrier.

Cerebrospinal-fluid profile in neuroborreliosis and its diagnostic significance.
Department of Clinical Microbiology, Faculty Hospital Brno, Czechia. firstname.lastname@example.org
Selected cerebrospinal-fluid (CSF) parameters (intrathecal synthesis of Borrelia-specific antibodies, oligoclonal IgG bands, CSF-to-serum quotient of albumin as a marker of blood-CSF barrier function and cytology) and typical CSF profile in neuroborreliosis were evaluated with the aim of elucidating possible clinical and laboratory similarities of neuroborreliosis (NB) and other neurological diseases (OND). From the cohort of 58 patients (38 diagnosed for NB, 20 with OND) NB patients had positive Borrelia-specific IgG antibodies in 97 % and positive Borrelia-specific IgM antibodies in 55 %; oligoclonal IgG bands were detected in 55%. The blood-CSF barrier was impaired in 89%, positive cytology was detected in 97% of the NB patients. Evaluation of specific intrathecal synthesis improves CSF diagnosis of NB, therefore, a combined CSF analysis has to be considered along with the clinical picture and medical history when formulating the diagnosis of NB.

[Laboratory methods for the diagnosis of clinical forms of Lyme borreliosis]
[Article in French]
Microbiologie, facult� de m�decine Ren�-Descartes, universit� de Paris-V, Paris, France. firstname.lastname@example.org
Methods used to diagnose Lyme borreliosis (LB) vary according to clinical presentations. A very good basis to clarify this nosological and clinical entity is the study published by the "European Concerted Action on Lyme Borreliosis" (EUCALB). In fact, only few studies were performed on cohorts of patients including all clinical forms of LB. For Erythema migrans, serology sensitivity is low (20% to 50%), while the sensitivity of culture or PCR reaches 50%. In early-complicated forms, serology is more sensitive (70 to 90%) with the presence of concomitant IgG and IgM. Screening for antibodies in CSF is very useful for the diagnosis of neuroborreliosis. For this clinical form, culture or PCR sensitivity is disappointing (10 to 30%). In arthritis and acrodermatitis chronica atrophicans (ACA), IgG serology is 100% positive with very high titers; however IgM serology is only positive in 5 to 10% of the cases. In ACA, culture sensitivity ranges from 20 to 60% and PCR sensitivity from 60 to 90%. Specificity of antibodies, natural exposure to the etiologic agent, and cross-reactivity are critical for the final interpretation of serological assessment. Only the use of "serological profiles" allows the exploitation of detailed results (isotypes, intensity). In this approach, IgG avidity could be constructive. The western-blot is intended to confirm the specificity of antibodies found in screening methods (Elisa).

We report on a patient who developed seronegative Lyme neuroborreliosis complicating chemotherapy for chronic lymphatic leukemia. After the fifth cycle of chemotherapy (FCR: fludarabine, cyclophosphamide, rituximab and prednisone) the 63-year-old patient developed night sweat, arthralgia in elbows, wrists, proximal interphalangeal joints (PIPs) and strong neuropathic pain in both legs, followed by paresthesia and hypesthesia in the feet, arms and face. Laboratory analysis revealed an elevated C-reactive protein (CRP), a slight elevation of liver enzymes and decreased IgG levels. Cerebrospinal fluid (CSF) analysis showed a lymphomononuclear pleocytosis and an elevation of protein. A broad diagnostic work-up was negative including a negative Borrelia IgG and IgM ELISA. The patient did not remember recent tick bites, but after specific questioning he recollected a transient erythema on his leg developing just before the start of the last cycle of chemotherapy. As the combination of neuropathic pain and arthralgia, the transient erythema and the lymphomononuclear pleocytosis raised the suspicion of Lyme neuroborreliosis, the patient was treated for 3 weeks with ceftriaxone. On therapy all symptoms resolved and CRP normalized. Retrospective PCR analysis of a CSF sample confirmed the clinical diagnosis by detecting Borrelia garinii DNA. This case demonstrates that in immunosuppressed patients borrelial serology may be negative and that additional diagnostic approaches (including tests for direct Borrelia detection) may be needed to demonstrate borrelial infection.

Despite the wide spectrum of clinical entities, eye involvement remains a rare event in patients with Lyme borreliosis. Most of ocular manifestations occur during the late phase of the disease. The infection needs to be considered along with more conventional causes of ocular inflammation, particularly in regions where Lyme disease is common. The pathogenesis of this condition remains controversial. Direct ocular infection and a delayed hypersensitivity mechanism may be involved at different disease stages. Uveitis and optic neuritis are the most common ocular complications. Serological testing lacks sensitivity and specificity. In atypical cases, ocular fluids sampling and analysis may be proposed. PCR seems to be an interesting diagnostic tool, allowing genotypic analysis. In the majority of cases, therapeutic strategy should be based on the association of antibiotics and corticosteroids. A new course of antibiotics may be prescribed to patients with chronic or relapsing inflammation due to bacterial persistence in ocular tissues.

[Clinical manifestations and epidemiological aspects leading to a diagnosis of Lyme borreliosis: neurological and psychiatric manifestations in the course of Lyme borreliosis]
[Article in French]

Lyme disease is associated with various systemic and neurological manifestations. The neurological and psychiatric manifestations of Lyme disease are more frequently observed during its secondary phase (stage 2) than during its late tertiary phase (stage 3). In stage 2, cerebrospinal fluid and bacterial tests are consistent with the ongoing infection. Painful meningoradiculitis, encephalomyelitis and encephalitis, and symptoms of depression are the most characteristic at this stage. The diagnosis should be based on the association of clinical, epidemiological, and biological features. Adequate treatment usually leads to recovery. In stage 3 of the disease, the link between neurological manifestations and initial infection is uncertain. Distal axonal polyneuropathy and chronic encephalopathy are the most frequently reported presentations.

The treatment of secondary and tertiary Lyme borreliosis is difficult because of antibiotic lack of efficacy. This fact may be explained by several factors: the specific pathophysiology, involving not only the presence of bacteria, but also immunological reactions. There is no specific method of diagnosis resulting in difficulties for good indication of treatment and to evaluate treatment efficacy. The literature review shows that ceftriaxone and doxycycline are the two most efficient antibiotics in this indication. Even if the methodology of the published studies is not always convincing, these two antibiotics proved their efficacy in articular as well as in neurological forms of the disease. In the late stage of borreliosis, antibiotics are less efficient. Various treatment modalities with different dosage or duration of treatment cannot let us conclude on a convincing regimen.

In a 29-y-old male with neuroborreliosis, partially responsive to ceftriaxone, myasthenia gravis with acetylcholine-receptor antibodies elevated almost 1000 times the upper reference limit was diagnosed. Pyridostigmine resolved all remaining neurological deficits. During a 1-y follow-up the patient remained symptom free, despite persistently high acetylcholine-receptor antibodies. They were attributed to epitope homology of the acetylcholine receptors and Borrelia surface antigens.

The neurological and psychiatric manifestations of Borrelia burgdorferi sensu lato are so numerous that Borrelia is also called the "new great imitator". Thus knowing about the multiple clinical aspects of neuroborreliosis is necessary for the clinician. We reviewed literature for "classical" neuroborreliosis such as acute meningoradiculitis or chronicle encephalomyelitis, but also for encephalitis, myelitis, polyneuritis, radiculitis and more controversial disorders such as chronic neurological disorders, ischemic and hemorrhagic stroke, and motor neuron disease. We specified every time on which basis each disorder was attributed to Lyme disease, particularly if European or American criteria were met. Every part of the nervous system can be involved: from central to peripheral nervous system, and even muscles. In endemic areas, Lyme serology must be assessed in case of unexplained neurological or psychiatric disorder. In case of positive serology, CSF assessment with intrathecal anti-Borrelia antibody index will be more efficient to prove the diagnosis.

Although estimates vary, the nervous system appears to be involved in 10% to 15% of patients infected with Borrelia burgdorferi. The resulting disorders, known collectively as neuroborreliosis or nervous system Lyme disease, generally respond well to antimicrobial therapy. Definitive treatment of nervous system infection typically consists of 2 to 4 weeks of parenteral ceftriaxone, cefotaxime, or high-dose penicillin (Class III). However, numerous European studies have shown that oral doxycycline is equally effective in patients with Lyme meningitis and cranial neuritis (Class II and III). This may be equally valid in patients infected with the strains prevalent in the United States, but this remains to be established.

Service de M�decine, Centre Hospitalier, Thiers. firstname.lastname@example.org
INTRODUCTION: The most frequent neurological expression of Lyme disease (borreliosis) during its secondary phase is meningoradiculitis, but atypical presentations occur. Lyme disease must be considered especially in endemic areas and during the summer (May-October). CASES: We report cases of two patients with unusual clinical presentations of neuroborreliosis. Both had acute inflammatory back pain, resistant to the usual analgesic treatment. Both patients responded negatively to questions about tick bites and erythema migrans. Laboratory tests revealed an inflammatory process in only one patient. Lyme disease was confirmed by lymphocytic meningitis and serological tests positive for Borrelia in blood (both cases) and cerebrospinal fluid (one case). Antibiotic treatment led to the disappearance of pain and the normalization of laboratory tests. DISCUSSION: Inflammatory back pain, even without radiculitis, may be related to Lyme disease in endemic areas.

Multiple sclerosis (MS) is a chronic disease of the central nervous system characterized by chronic inflammation and demyelination. Studies suggested that the viral, especially Epstein-Barr virus infection, and bacterial infections, especially Borrelia burgdorferi infection, play a role in etiology of MS. MS prevalence parallels the distribution of the Lyme disease pathogen B. burgdorferi. Criteria used for diagnosis of MS can also be fulfilled in other conditions such as Lyme disease, a multisystem disorder resulting from infection by the tick-borne spirochete, B. burgdorferi. In the late period of Lyme disease demyelinating involvement of central nervous system can develop and MS can be erroneously diagnosed. A Lyme borreliosis can mimick central nervous system lymphoma. Also, B. burgdorferi has been implicated not only in etiology of MS, but also in etiology of lymphoma. Studies suggested that there is an increased risk of non-Hodgkin lymphoma in patients, who had a history of autoimmune diseases such as MS and that both non-Hodgkin's lymphomas and Hodgkin's disease were associated with Epstein-Barr virus infection. A small group of lymphomas called primary effusion lymphomas (PEL) is a recently individualized form of non-Hodgkin's lymphoma (WHO classification) that exhibit exclusive or dominant involvement of serous cavities, without a detectable solid tumor mass. These lymphomas have also been linked to Epstein-Barr virus and human herpes virus type 8 infections but virus negative cases have been described. Therefore, we propose that MS and neuroborreliosis are linked to central nervous system primary effusion lymphomas. As a first step in confirming or refuting our hypotheses, we suggest a thorough study of CSF in the patients suspected for the diagnosis of MS and Lyme borreliosis.

Decreased up-regulation of the interleukin-12Rbeta2-chain and interferon-gamma secretion and increased number of forkhead box P3-expressing cells in patients with a history of chronic Lyme borreliosis compared with asymptomatic Borrelia-exposed individuals.

Lyme borreliosis (LB) can, despite adequate antibiotic treatment, develop into a chronic condition with persisting symptoms such as musculoskeletal pain, subjective alteration of cognition and fatigue. The mechanism behind this is unclear, but it has been postulated that an aberrant immunological response might be the cause. In this study we investigated the expression of the T helper 1 (Th1) marker interleukin (IL)-12Rbeta2, the marker for T regulatory cells, forkhead box P3 (FoxP3) and the cytokine profile in patients with a history of chronic LB, subacute LB, previously Borrelia-exposed asymptomatic individuals and healthy controls. Fifty-four individuals (12 chronic LB, 14 subacute LB, 14 asymptomatic individuals and 14 healthy controls) were included in the study and provided a blood sample. Mononuclear cells were separated from the blood and stimulated with antigens. The IL-12Rbeta2 and FoxP3 mRNA expression was analysed with real-time reverse transcription-polymerase chain reaction (RT-PCR). The protein expression of IL-12Rbeta2 on CD3(+), CD4(+), CD8(+) and CD56(+) cells was assessed by flow cytometry. Furthermore, the secretion of interferon (IFN)-gamma, IL-4, IL-5, IL-10, IL-12p70 and IL-13 was analysed by enzyme-linked immunospot (ELISPOT) and/or enzyme-linked immunosorbent assay (ELISA). Chronic LB patients displayed a lower expression of Borrelia-specific IL-12Rbeta2 on CD8(+) cells and also a lower number of Borrelia-specific IFN-gamma-secreting cells compared to asymptomatic individuals. Furthermore, chronic LB patients had higher amounts of Borrelia-specific FoxP3 mRNA than healthy controls. We speculate that this may indicate that a strong Th1 response is of importance for a positive outcome of a Borrelia infection. In addition, regulatory T cells might also play a role, by immunosuppression, in the development of chronic LB.

Serological tests for detection of borrelial antibodies are frequently used in laboratory diagnostics of Lyme borreliosis. Unfortunately these tests are not standardized and the results obtained with different assays may not be concordant. The aim of the present study was to compare two different serological tests, IFA and LIAISON, for detection of Borrelia burgdorferi sensu lato IgM and IgG antibody. We analyzed the serological immune response in 383 patients with different clinical manifestations of Lyme borreliosis and in 49 healthy blood donors. LIAISON detected IgM and IgG antibodies more often than IFA in all groups of patients except those with chronic Lyme borreliosis. The differences were significant for IgM and IgG antibodies in patients with solitary erythema migrans and in those with early disseminated Lyme borreliosis. There was no significant difference in the specificity of the two tests.

Although pediatric Lyme borreliosis (LB) need not be a separate nosological entity, there are clinically important differences in presentation, antibiotic regimens and outcomes in children, which provide lessons that can be extrapolated to the disease as it affects adults. A large proportion of the worldwide data is obtained from children. The aim of this presentation is not to present an exhaustive review of the pediatric literature, but to review a selection of pediatric studies that have made a significant contribution to our body of knowledge in Lyme borreliosis.

A strong initial inflammatory response is important in neuroborreliosis. Since complement is a main player in early inflammation, we monitored the concentration and activation of complement in plasma and cerebrospinal fluid from 298 patients, of whom 23 were diagnosed with neuroborreliosis. Using sandwich ELISAs, we found significantly elevated levels of C1q, C4, C3, and C3a in cerebrospinal fluid, but not in plasma, in patients with neuroborreliosis. This finding indicates that complement plays a role in the human immune response in neuroborreliosis, that the immunologic process is compartmentalized to the CNS, and that complement activation may occur via the classical pathway.

Lyme borreliosis is considered to be an emerging infection in some regions of the world, including Portugal. The first Portuguese human case of Lyme borreliosis was identified in 1989. Since 1999, this disease is considered a notifiable disease (DDO) in Portugal, but only a few cases are reported each year, which does not allow consistent analysis of risk factors and the impact on public health. In this study the authors analyse the data available at the Centre for Vectors and Infectious Diseases Research (CEVDI) laboratory, at the Instituto Nacional de Saude Dr. Ricardo Jorge (National Institute of Health, INSA) during the past 15 years (1990-2004) and evaluate them against the registry of national reported cases (1999-2004). Serological tests were the basis for laboratory diagnosis. Data on year of diagnosis, sex, age, geographical origin and clinical signs are available for 628 well documented Portuguese positive cases. The number of cases per year varied between 2 and 78, with the highest number of cases reported in 1997. Of the positive cases, 53.5% were female and the age group most affected was 35-44 years old. Neuroborreliosis was the most common clinical manifestation (37.3%). Human cases were detected in 17 of the 20 regions of Portugal, and the highest number of laboratory confirmed cases were from the Lisbon district. The comparison of the number of notified cases and the number of positive cases confirmed by our laboratory show that Lyme borreliosis is clearly an underreported disease. Due to the scattered distribution of the positive cases and the low prevalence of the tick species Ixodes ricinus, the most effective prevention measure for Lyme borreliosis in Portugal is education of the risk groups on how to prevent tick bites.

Neurological manifestations of Lyme disease are usually accompanied by inflammatory changes in the cerebrospinal fluid (CSF) and the recruitment of activated T cells into the CSF compartment. In order to characterize the phenotype and identify target antigens of CSF-infiltrating T cells in early neuroborreliosis with central nervous system (CNS) involvement, we combined T-cell cloning, functional testing of T-cell responses with positional scanning synthetic combinatorial peptide libraries, and biometric data analysis. We demonstrate that CD4+ gamma interferon-producing T cells specifically responding to Borrelia burgdorferi lysate were present in the CSF of a patient with acute Lyme encephalitis. Some T-cell clones recognized previously uncharacterized B. burgdorferi epitopes which show a specific enrichment for lysine, such as the heat shock-induced chaperone HSP90. Degenerate T-cell recognition that included T-cell responses to borrelia-specific and CNS-specific autoantigens derived from the myelin protein 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNPase) could be demonstrated for one representative clone. Our results show that spirochetal antigen-specific and Th1-polarized CD4+ lymphocytes infiltrate the CSF during monophasic CNS symptoms of Lyme disease and demonstrate that cross-recognition of CNS antigens by B. burgdorferi-specific T cells is not restricted to chronic and treatment-resistant manifestations.

Human infection by Borrelia burgdorferi, the etiological agent for Lyme disease, can result in serious acute and late-term disorders including neuroborreliosis, a degenerative condition of the peripheral and central nervous systems. To examine the mechanisms involved in the cellular pathogenesis of neuroborreliosis, we investigated the ability of B. burgdorferi to attach to and/or invade a panel of human neuroglial and cortical neuronal cells. In all neural cells tested, we observed B. burgdorferi in association with the cell by confocal microscopy. Further analysis by differential immunofluorescent staining of external and internal organisms, and a gentamicin protection assay demonstrated an intracellular localization of B. burgdorferi. A non-infectious strain of B. burgdorferi was attenuated in its ability to associate with these neural cells, suggesting that a specific borrelial factor related to cellular infectivity was responsible for the association. Cytopathic effects were not observed following infection of these cell lines with B. burgdorferi, and internalized spirochetes were found to be viable. Invasion of neural cells by B. burgdorferi provides a putative mechanism for the organism to avoid the host's immune response while potentially causing functional damage to neural cells during infection of the CNS.

In childhood, facial nerve palsy and headache are typical symptoms of second and third stage neuroborreliosis. While focal demyelination is occasionally observed on MRI scans, the appearance of a tumorous lesion is extremely rare. The case of a 10-year-old girl with neuroborreliosis mimicking a space-occupying lesion in the brainstem, without any previously recognized manifestations of borreliosis, is reported.

Neuroborreliosis is a form of borreliosis that affects the central and/or peripheral nervous system. Although it can mimic neurologic and ophthalmologic disorders such as multiple sclerosis and optic neuritis, visual evoked potential (VEP) examination is usually not used in neuroborreliosis diagnostics. Combined VEP testing (pattern-reversal VEPs and VEPs produced in response to linear and radial motion) was performed in 81 patients with neuroborreliosis verified by laboratory results (positive polymerase chain reaction or intrathecal antibodies production). Thirty-four patients reported diplopia or blurred vision related to borreliosis. In 33 (40%) patients the VEPs were delayed: motion-onset VEPs were pathologic in 22 (27%) patients, reversal VEPs in 5 (6%) patients, and both VEP types in 6 (7%) patients. The findings suggest that VEP testing (especially the motion-onset VEP testing) can confirm CNS involvement. Much higher sensitivity of motion-onset VEPs in comparison with reversal VEPs can result from rather selective (earlier) involvement of the magnocellular system or the dorsal stream of the visual pathway.

The laboratory diagnosis of Lyme disease in Denmark is reviewed with recommendations for serological testing. In Denmark the laboratory testing is performed with an ELISA technique. Most laboratories use an assay based on purified flagella antigen. The two-tier approach with Western Blot as confirmatory testing is not recommended since the contribution to the diagnostic specificity is only marginal. Predictive values of Lyme serology are presented, based on the estimated prevalence of the different stages of Lyme disease in Denmark.

Relapsing fever (RF) is a spirochetal infection characterized by relapses of a febrile illness and spirochetemia due to the sequential appearance and disappearance of isogenic serotypes in the blood. The only difference between isogenic serotypes is the variable major outer membrane lipoprotein. In the absence of specific antibody, established serotypes cause persistent infection. Studies in our laboratory indicate that another consequence of serotype switching in RF is a change in neuroinvasiveness. As the next step to elucidate this phenomenon, we studied the interaction of the neurotropic Oz1 strain of the RF agent Borrelia turicatae with the cerebral microcirculation. During persistent infection of antibody-deficient mice, we found that serotype 1 entered the brain in larger numbers and caused more severe cerebral microgliosis than isogenic serotype 2. Microscopic examination revealed binding of B. turicatae to brain microvascular endothelial cells in vivo. In vitro we found that B. turicatae associated with brain microvascular endothelial cells (BMEC) significantly more than with fibroblasts or arachnoidal cells. The binding was completely eliminated by pretreatment of BMEC with proteinase K. Using transwell chambers with BMEC barriers, we found that serotype 1 crossed into the lower compartment significantly better than serotype 2. Heat killing significantly reduced BMEC crossing but not binding. We concluded that the interaction of B. turicatae with the cerebral microcirculation involves both binding and crossing brain microvascular endothelial cells, with significant differences among isogenic serotypes.

BACKGROUND: The most common cause of Lyme neuroborreliosis in Europe is Borrelia garinii, followed by Borrelia afzelii. However, no series describing patients with culture-confirmed cases of Lyme neuroborreliosis have been published, and no comparison of findings for patients with B. garinii and B. afzelii isolated from cerebrospinal fluid (CSF) has been reported. METHODS: All adult patients identified at a single medical center during a 10-year period who had borreliae isolated from CSF and typed as B. garinii or B. afzelii (using large DNA fragment patterns obtained with the MluI restriction endonuclease and separated with pulsed-field gel electrophoresis) were included. RESULTS: A comparison of 23 patients who had B. garinii isolated from CSF with 10 patients who had B. afzelii isolated from CSF revealed that a reliable clinical diagnosis of Lyme neuroborreliosis (before obtaining a CSF culture and intrathecal borrelial antibody production result) was established more frequently in the B. garinii group than in the B. afzelii group (19 of 23 patients vs. 1 of 10 patients). Patients in the B. garinii group reported radicular pains and expressed meningeal signs more often, but reported dizziness less often (occurrences of several other symptoms and/or signs were comparable). Lymphocytic pleocytosis, as well as several other CSF abnormalities, were frequent among patients with B. garinii isolated from CSF but were rare among patients in the B. afzelii group. CONCLUSIONS: Patients with B. garinii isolated from their CSF have a distinct clinical presentation, compared with patients with B. afzelii. B. garinii causes what, in Europe, is appreciated as typical early Lyme neuroborreliosis (Bannwarth syndrome), whereas the clinical features associated with B. afzelii are much less specific and more difficult to diagnose.

The aim of the study was the evaluation of the efficiency of Western blot (EcoLine) test detecting simoultanous presence of IgM and IgG antibodies against B. burgdorferi in diagnosis of early and late stage of Lyme borreliosis. The comparison of results achieved by performing test Western-blot, ELISA (based on recombinant antigens of three genospecies of Borrelia) and EIA (based on antigens of one B. burgdorferi genospecies). The tests Western blot: EcoLine (Virotech) with antygens "in vivo", ELISA Borrelia IgM, IgG recombinant (Biomedica), EIA: B. b. ss. IgG, EIA B. garinii IgG, EIA B. afzelii IgG (TestLine) were used. Results showed efficacy of detecting IgM, IgG antibodies against VlsE simultanously and IgG antibodies against "in vivo" antigens in diagnosis of early stages of Lyme disease when atypical picture skin lessions arise diagnostic doubts and in discerning early and late stage of disease. The EIA tests based on one B. burgdoreferi genospecies seem less effective in comparison to ELISA tests based on 3 genospecies antigens.

B. burgdorferi can evade the destructive effects of the immune system by binding host's complement regulators, which leads to inhibition of the complement activation cascade. Complement activity is blocked by CRASPs--complement regulator acquiring surface proteins. Complement resistance might therefore represent one major pathogenic factor favoring spirochete transmission to the vertebrate host, as well as determine host reservoirs of Borrelia burgdorferi genospecies. The cause of neuro-psychiatric disorders developing in some patients with Lyme borreliosis is still unknown. One of the hypotheses links them to neuro-hormonal disturbances induced by B. burgdorferi infection.

OBJECTIVE: The aim of this study was to evaluate the serum and CSF concentration of soluble intercellular adhesion molecules sICAM-1, sICAM-2, sICAM-3 and proinflammatory cytokine IFNgamma in patients with tick-borne encephalitis (TBE) and neuroborreliosis. METHODS: The study group consisted of 40: 20 with TBE meningitis and 20 with Lyme meningitis. The serum and CSF levels of adhesion molecules and IFNgamma were determined by ELISA assay twice: before and after treatment. RESULTS: Before treatment the concentrations of adhesion molecules and IFNgamma in serum as well as in CSF were significantly higher in both studied groups than in control group (with the exception of the serum level of sICAM-2 in TBE group). After the treatment, the serum parameters in TBE group decreased to the control level. CSF levels were also reduced, but still remained higher than in the control group. In patients with neuroborreliosis serum concentration of sICAM-1 and sICAM-2 did not change as compared with its level before treatment but other studied parameters in serum and CSF decreased significantly. CONCLUSIONS: The results of our study confirm the participation of intercellular adhesion molecules in the pathogenesis of viral (TBE) and bacterial (neuroborreliosis) neuroinfections.

[Multifocal central nervous system lesions --multiple sclerosis or neuroborreliosis?]
[Article in Polish]
Klinika Neurologii AM w Bia�ymstoku.
Multiple sclerosis is the most frequent multifocal disease of the central nervous system, but in a diagnosis of atypical cases about 100 other diseases should be considered. Neuroborreliosis plays a particular role among them, especially in endemic regions. Difficulties result from similarities of clinical symptoms and lack of specific diagnostic investigations. Diagnostic procedures in neuroborreliosis are mostly based on laboratory analyses and serologic examinations of serum and cerebrospinal fluid, in connection with a clinical picture and an epidemiological state. Since the year 2001, multiple sclerosis neurological diagnostic is based on the diagnostic criteria established under the auspices of The US National Multiple Sclerosis Society and International Federation of Multiple Sclerosis Societies. Those recommendations regarding relapsing-remitting MS and primary progressing MS are discussed in this paper. Current knowledge of those diseases warrants cautiousness in the diagnostic of atypical cases.

Clinical picture of Borrelia burgdorferi infection has been presented in 89 children from Lodz region. The analysis showed significant domination of cases with non specific symptoms (41.6%) as: fever or headache and cases with affected central and peripheral nervous system (30.3%). Peripheral cranial nerves paralysis and symptoms of cerebrospinal meningitis dominated among children with neuroborreliosis. Unlike descriptions concerning adults, majority of the observed symptoms were changes characteristic for I stage of the disease. Dermatosis was found only in (19%) child and symptoms of arthritis in (9%) of them. Contact with tick was stated in 56.8% of the analysed children. Incidence of the disease occurred throughout the whole year, more frequently in summer and autumn months.

Department of Medical Microbiology, Center of Infectious Diseases, Leiden University Medical Center, PO Box 9600, 2300 RC, Leiden, The Netherlands.
This study reports the development and evaluation of an internally controlled real-time PCR targeting the ospA gene for detection of Borrelia burgdorferi sensu stricto, Borrelia garinii, Borrelia afzelii and Borrelia valaisiana. DNA was extracted using QIAamp DNA Blood Mini kit columns. DNA from 33 B. burgdorferi sensu lato strains reacted in the assay, whereas no reactivity was observed with DNA from four relapsing fever Borrelia spp., 11 unrelated spirochaetes, and 31 unrelated microorganisms. The quantitative sensitivity of the assay was 1-10 fg of Borrelia DNA and one to five cultured Borrelia spirochaetes. Cerebrospinal fluid (CSF) specimens from 70 patients sent for routine testing for neuroborreliosis, and three CSF specimens containing B. garinii were also tested. Positive PCR results were obtained with all three culture-confirmed neuroborreliosis specimens, five of ten neuroborreliosis specimens with specific antibodies in CSF and pleocytosis, none of nine specimens from possible cases of early neuroborreliosis (antibodies in serum, CSF pleocytosis, no antibodies in CSF), one of 15 specimens from patients with active or past Lyme disease with neurological signs (antibodies in serum, no pleocytosis or antibodies in CSF), and none of 36 specimens from patients without Lyme borreliosis (no antibodies in serum or CSF). Overall, the real-time PCR assay enabled sensitive and specific detection of all B. burgdorferi sensu lato species tested. The PCR had a sensitivity of 50% in patients with neuroborreliosis. The main diagnostic role of the assay could be to confirm neuroborreliosis in patients for whom the diagnosis is doubtful.

Every manifestation of Lyme borreliosis needs to be treated with antibiotics. The type of antibiotic applied and duration of treatment will depend on the stage and severity of the disease. Erythema migrans, Borrelia lymphocytoma, Lyme arthritis and acrodermatitis chronica atrophicans are primarily treated orally. If neurological symptoms, severe Lyme carditis or eye manifestations are present, intravenous treatment is initially recommended. For oral therapy, doxycycline, amoxicillin, cefuroxime and, if intolerance is shown, azithromycin, are available. For intravenous treatment ceftriaxone, cefotaxime or penicillin G is employed. The overall prognosis for treated Lyme borreliosis is good. However, in particular when manifestations with substantial organic injury have persisted, incomplete healing must be expected. With the exception of erythema migrans, every manifestation should be subjected to a careful diagnostic work-up prior to the start of treatment, because premature antibiotic administration is not only associated with an elevated risk for the patient, but can also mask important diagnostic signs.

Is neuroborreliosis a medical emergency?
NYU School of Medicine, Great Neck, NY, USA. Halperin@LINeuro.com
Although Lyme disease affects the nervous system in many ways (collectively known as neuroborreliosis), only rarely does it present as a medical emergency. In extreme cases, it may cause (1) encephalitis, (2) a rapidly progressive peripheral neuropathy, or (3) a painful truncal radiculopathy that may be confused with a severe visceral process. Knowing when to consider this spirochetosis in the differential diagnosis requires an understanding of its true clinical spectrum, and of an appropriate diagnostic and therapeutic approach.

We report the case history of a patient who suffered a subarachnoid hemorrhage (SAH) in association with early Lyme neuroborreliosis. After a tick bite, this patient developed erythema chronicum migrans and complained of stinging radicular pain in both legs. A computed tomography (CT) scan was performed because of acute headache and nuchal rigidity, which revealed an occipital SAH. Cerebrospinal fluid analysis provided further evidence of acute neuroborreliosis. Digital substraction angiography showed irregularities in the right posterior cerebral artery, which might be due to vasculitis, but no aneurysms.

Simultaneous co-infections of Borrelia burgdorferi sensu lato and HIV-1 are rare events, with only six published cases. A case of acute neuroborreliosis with facial palsy, meningoradiculitis (Bannwarth's syndrome) in an HIV-1 positive individual is described. Diagnosis was confirmed by Western immunoblot analysis of serum and CSF and by proof of intrathecal production of antibodies against B. garinii. The patient was successfully treated with cefotaxime. In all published HIV+ cases, the course of borreliosis did not differ from that of the HIV negative population and the prognosis in properly treated patients was good.

Lyme disease (LD) is due to infection with Borrelia burgdorferi (B. burgdorferi). We analysed some aspects of epidemiology and clinical manifestation of borreliosis. We tried to estimate the efficiency of diagnostic methods and treatment. We analyzed medical documentation of 300 patients with LD treated in our department between 1993-2001. The diagnosis was made according to Lyme Disease Foundation's criteria. Patients suffering from LD were divided into 3 groups according to stages of the disease. The most frequent manifestation of LD was erythema migrans (EM). The number of LD cases had increased during the observation time. The exposition to tick-bites was greater during summer and early autumn. The great number of patients with EM was observed at the same time. Cases of Lyme arthritis (LA), disseminated EM, Lyme carditis (LC) and neuroborreliosis represented the group number 2. LA, uveitis and acrodermatitis chronica atrophicans (ACA) were diagnosed in the third group of patients. Serological markers of B. burgdorferi infection were found in about 50% of cases of EM and in each patient in group 2 and 3. Complete recovery after antibiotic therapy was observed in every case in early LD and partial one in the late stage.

Neuroborreliosis and the pediatric population: a review.
Section of Child Neurology, University of Miami School of Medicine, Miami, Florida 33136, USA. email@example.com
AIMS: To review the medical literature on neuroborreliosis, in particular its clinical features in both adults and children, and highlight the differences between the two groups, with an emphasis on the pediatric population. DEVELOPMENT: The neurologic manifestations of the disease variably affect different areas of the neuroaxis, central or peripheral, and can present with early or late symptomatology, depending on the age group. Although the literature includes a wide range of neurologic abnormalities, the most frequent symptom reported in the pediatric population is headache, and the most common sign being facial palsy. An immunologic process with cross-reacting antibodies and antibodies directed against neuronal proteins may exist as the causative factor. Because of characteristic cerebrospinal fluid (CSF) findings, CSF examination and serologic testing for Borrelia burgdorferi, the causative agent, should be performed in patients, particularly if a child, having been in an endemic area, presenting with an acute neurologic disorder of unexplained etiology. Treatment with antibiotics, if initiated early-on, is curative, especially in children. CONCLUSIONS: The pediatric population carries the highest risk for Lyme disease relative to other age groups. Younger patients tend to be more acutely affected, with involvement primarily of the central nervous system, exhibiting an inflammatory response in the CSF and signs/symptoms of aseptic meningitis and facial nerve palsy, whereas older patients present with features of peripheral nervous system pathology, tipically with a radiculopathy. Despite having a greater incidence of neuroborreliosis, the clinical course in most children is milder and shorter than that reported for adults.

BACKGROUND AND PURPOSE: Neuroborreliosis is frequently indistinguishable from multiple sclerosis (MS) on both clinical and radiologic grounds. By using MR imaging, we assessed "occult" brain white matter (WM), brain gray matter (GM), and cervical cord damage in patients with neuroborreliosis in an attempt to achieve a more accurate picture of tissue damage in these patients, which might contribute to the diagnostic work-up. METHODS: We studied 20 patients with neuroborreliosis and 11 sex- and age-matched control subjects. In all subjects, we acquired dual echo, T1-weighted, diffusion tensor (DT) and magnetization transfer (MT) MR imaging scans of the brain and fast short-tau inversion recovery and MT MR imaging scans of the cervical cord. T2-visible lesion load was measured by using a local thresholding segmentation technique. Mean diffusivity and fractional anisotropy histograms of the brain and cervical cord MT ratio histograms were produced. Normalized brain volumes (NBV) were measured by using SIENAx. RESULTS: Brain T2-visible lesions were detected in 12 patients, whereas no occult damage in the normal-appearing WM and GM was disclosed by using MT and DT MR imaging. No macroscopic lesions were found in the cervical cord, which was also spared by occult pathology. NBV did not differ between patients with neuroborreliosis and control subjects. CONCLUSION: This study shows that, contrary to what happens in MS, occult brain tissue damage and cervical cord pathology are not frequent findings in patients with neuroborreliosis. These observations might be useful in the diagnostic work-up of patients with neuroborreliosis and T2 brain lesions undistinguishable from those of MS.

To study pathogenic mechanisms of Lyme meningoradiculitis, dorsal root ganglia (DRG) cells and two neuronal cell lines (B50, SH-SY5Y) were incubated with Borrelia garinii, the Borrelia species most frequently isolated from CSF of Lyme neuroborreliosis patients in Europe. We demonstrated that (I) OspA-positive B. garinii adhere to neuronal cells, (II) Borrelia adhesion can be blocked by a monoclonal antibody against OspA, (III) preincubation with proteoglycans interferes with the adhesion process and (IV) rOspA directly binds to the proteoglycans. This indicates that both OspA and the cell bound proteoglycans are involved in the attachment of B. garinii to neuronal cells.

OBJECTIVES: We aimed to gain insights into the pathogen-specific differences in early adaptive immune responses following central nervous system infections with Borrelia burgdorferi and viral pathogens by studying the immunophenotypic patterns of T-cell activation. Moreover, we wished to determine whether the expression of T-cell activation markers reflects disease activity in multiple sclerosis (MS). METHODS: Proportions of cerebrospinal fluid T-cells expressing the markers HLA-DR, CD25 and CD38 were determined in patients with MS (n = 40), acute viral meningomyeloradiculoneuritis (VID, n = 26), early neuroborreliosis (NB, n = 23) and non-inflammatory neurologic diseases (n = 51) by using flow cytometry. In relapsing-remitting MS, disease activity was assessed by clinical examination and magnetic resonance imaging. RESULTS: For each of the surface markers that were examined, significant differences in T cell proportions were found between patient groups. The proportion of HLA-DR+ T cells was higher and that of CD25+ T cells lower in NB compared with VID. These differences were attributable only to the early phase of the disease (< or = 6 days after symptom onset). Among MS patients, there was a trend for higher proportions of T cells expressing activation markers in patients with gadolinium-enhancing lesions. CONCLUSIONS: The decreased CD25 expression in NB may reflect immunomodulatory effects of B. burgdorferi facilitating persistent infection. Larger prospective studies of T-cell activation markers for ascertaining the association between cellular markers and clinical surrogates of disease activity in MS are warranted.

This case report discusses a patient with co-occurring neuroborreliosis and Alzheimer's disease (AD). Although no claim is made for causality nor is there objective evidence that spirochetes are involved in AD, co-infection may exacerbate the symptoms of either neuroborreliosis or AD. Much is to be learned about the role of spirochetes in degenerative central nervous system disease.

Clinical aspects of neuroborreliosis and post-Lyme disease syndrome in adult patients.

The diagnostic criteria of active neuroborreliosis include inflammatory changes of the cerebrospinal fluid (CSF) and an elevated specific Borrelia CSF-to-serum antibody index, indicating intrathecal Borrelia antibody production. Patients with neuroborreliosis are usually treated with intravenous ceftriaxone for 2-3 weeks. In case of allergy, doxycycline may be used. Treatment efficacy is detected by the improvement of the neurological symptoms and the normalization of the CSF pleocytosis. The measurement of serum and CSF antibodies is not suitable for follow-up, because they frequently persist. Post-Lyme disease (PLD) syndrome is characterized by persistent complaints and symptoms after previous treatment for Lyme borreliosis, e.g., musculoskeletal or radicular pain, dysaesthesia, and neurocognitive symptoms that are often associated with fatigue. There is no formal definition of the PLD syndrome, and its pathogenesis is unclear. Recent controlled studies do not support the use of additional antibiotics in these patients, but recommend primarily symptomatic strategies.

Krooninen tai myöhäisessä muodossa oleva Lymen tauti
Asiantuntijat tunnustavat nyt, että Lymen tauti voi saada kroonisen muodon, ja vaikka emme tiedä tarkalleen, kuinka usein sitä esiintyy, viimeisimpien tutkimusten mukaan Saksassa on enintään 100 000 uutta tapausta ja Yhdysvalloissa jopa 300 000 uutta tapausta.
Mutta mikä ero on:
Lymen taudin yleinen krooninen muoto
Kroonisessa neuroborrelioosissa tauti ilmenee yksinomaan hermostoon, mutta ei muihin elinjärjestelmiin. Kaikissa hermoston osissa - keskushermostossa, kallon hermoissa, ääreishermostossa ja vegetatiivisessa hermostoon - voidaan vaikuttaa eri määrin. Tästä syystä potilaat ilmoittavat usein vaihtelevasta epämukavuudesta.
Siksi Lyme-potilailla todetaan usein mielisairaus; lääkärit harvoin katsovat, että heidän oireensa voivat olla kroonisen infektion seurausta.
Yleinen krooninen muoto (myöhäinen muoto) viittaa monisysteemiseen sairauteen , joka vaikuttaa hermostoon ja muihin elinjärjestelmiin. On osoitettu, että eri Borrelia-kannat kannattavat eri elinjärjestelmiä ja voivat siten aiheuttaa erilaisia oireita.
Kroonisen Lymen taudin oireet
Lymen tauti on monisysteeminen sairaus, mikä tarkoittaa, että se voi vaikuttaa useisiin elimiin ja elinjärjestelmiin samanaikaisesti; Potilaat, joilla on krooninen (myöhäinen muoto) Lymen tauti ja rinnakkaisinfektiot, ilmoittavat monia erilaisia oireita (ks. yleiskatsaus alla).
Siksi sekä lääkäreiden että potilaiden on vaikea määrittää nämä epäspesifiset oireet yksittäiseen krooniseen infektioon, koska potilaalla on yleensä useampi kuin yksi infektio.
Lisäerottelua varten voit käyttää tätä tarkistuslistaa monisysteemisten sairauksien oireisiin: saksa, englanti, ranska, espanja, italia, venäjä ja suomi.
Suurin osa Lymen tautia sairastavista potilaista ilmoittaa:
Jaksottaiset oireet, jotka tulevat ja menevät ...
Keskeinen päivämäärä tai kuukausi, jolloin "kaikki alkoi ..."
Tärkeä päivämäärä tai kuukausi ”kun minusta tuli toinen henkilö…”
Avainpäivämäärä tai kuukausi ”kun aloin käydä säännöllisesti asiantuntijoiden luona…”
Potilaat ilmoittavat myös joskus, että heidät on diagnosoitu väärin mielenterveydellisiksi fyysisen sairauden sijaan.
