Tutkimuksissa on jo aiemmin todettu borrelia-bakteerin yhteys lisääntyneeseen riskiin sairastua sekä hyvänlaatuisiin että pahanlaatusiin kasvaimiin. Allaolevan Tanskalais-Ruotsalaisen tutkimuksen (2010) mukaan borrelia-bakteeri lisää selkeästi riskiä sairastua tiettyyn imusolmukesyöpään - mantelcelllymfom. Syöpään ei ole tällä hetkellä tehokasta hoitoa. Tutkimukseen osallistui 3000 eri lymfoomaan sairastunutta henkilöä.

Lyme disease may increase the risk of cancer

Lyme disease increases the risk of contracting a rare but difficult to treat
form of lymph node cancer, mantelcellymfom. It is clear from a large
Danish-Swedish study, published in the online edition of the respected trade
journal Blood.

"Our results provide support for Lyme infection may contribute to the emergence
of mantelcellymfom," said Professor Bengt Glimelius at the Academic Hospital
cancer clinic in Uppsala.

He is one of the researchers behind the study, which was made in the light of
several previous reports of a possible relationship between Lyme infection and
lymph node cancer. In particular, DNA from Lyme bacteria found inside cancer
cells in the skin of some patients with lymph node cancer.

The new study includes more than 3000 Danish and Swedish patients with various
forms of lymphoma and a similar number of healthy comparison individuals of the
same age.
All underwent an extensive telephone interview in which they were asked
questions including the previous tick bites and Lyme infections.
Blood samples to detect antibodies to Lyme bacteria were taken from about half
of both groups. Such antibodies are a type of indication of a previous or
current Lyme infection.

To have been tick-bitten was common both among patients and among comparison
subjects. In both groups reported more than 40 percent said they had a tick
bite.
As for the presence of antibodies against Borrelia in the blood there was no
safe distinction between patients with lymphoma and healthy individuals in the
comparison group.

In contrast, Lyme infection more than three times more common among patients
with mantelcellymfom
than in the control group. Nearly one in seven patients
with this form of lymphoma, but was only one 33rd person in the control group
had a Lyme infection.

"This indicates that the Lyme infection is a risk factor that may underlie some
cases of mantelcellymfom. This must be confirmed in further studies," says Bengt
Glimelius.

Previously known as MALT lymphoma of the stomach and the eye associated with
infection caused by Helicobacter pylori and Chlamydia species Chlamydia psittai.
Both types of lymphoma are often treated successfully with antibiotics.
"In my opinion it is more questionable whether antibiotics can act as
mantelcellymfom treatment of patients with Lyme disease. With mantelcellymfom
patients have cancer cells with many more genetic mutations than in MALT
lymphoma of the stomach or eye," says Bengt Glimelius.

While he hopes that continued research will provide more detailed knowledge of
the relationship between Lyme and mantelcellymfom.
"Knowledge about the mechanisms behind this relationship will hopefully give
suggestions for new ways to treat mantelcellymfom. There is currently no cure
for this cancer, which has a worse prognosis than other malignant lymphomas,"
says Bengt Glimelius.

Mikro-organismien (bakteeri, virus, parasiitit) osuus syöpien syntyyn on ollut tunnettua jo sadan vuoden ajan. Syöpien syntyyn yhteydessä olevia bakteereita ovat esim. borrelia-bakteeri, helikobakteeri, klamydia psitacii ja streptokokki (bovis). Niiden tiedetään aiheuttavan esim. maksa-, suolisto-, silmä-, tai ihosyöpiä.

Abstract

Microorganism involvement in cancer has been known for over a century, and different types of parasites, bacteria and viruses have been associated with oncogenic processes. Among the bacteria, the first recognised was Helicobacter pylori which causes gastric cancer and might be related to extra-gastric cancer in humans. Helicobacter hepaticus has been associated with liver cancers using animal models. Other bacteria such as, Chlamydia psitacii, Borrelia burgdorferi and Streptococcus bovis have been associated with ocular, skin and colorectal cancers, respectively. Also, a commensal bacterium in the human intestine, Bacteroides fragilis, has been linked, very recently, with colorectal cancer using animal models.

Cysts, various cancer, tumors, lesions

?In many of my [Lyme] patients, cysts are found not uncommonly in various locations: thyroid, breast, liver, bone, ovary, skin, pineal gland, and kidney. ? LD can cause an interstitial cystis leading to bladder pain relieved by urination.

?A growing body of research suggests that a number of viruses, bacteria, and parasites cause cancer in humans, thus providing new possibilities for treatment and prevention of cancer. In 1997, the World Health Organization estimated that up to 84% of cases of some cancers are attributable to viruses, bacteria, and parasites and that more than 1.5 million (15%) new cases each year could be avoided by preventing the infectious disease associated with them. ? The pathogenic mechanisms by which infectious agents cause cancer have not been resolved but they appear to be diverse. ?

?We concluded that women with endometriosis are more likely to have chronic fatigue syndrome, systemic lupus erythematous, Sjögren's syndrome, rheumatoid arthritis, multiple sclerosis, and other autoimmune inflammatory and endocrine diseases.

?Infection by bacteria, parasites or viruses and tissue inflammation such as gastritis, hepatitis and colitis are recognized risk factors for human cancers at various sites. ? Studies on the type of tissue and DNA damage produced by NO and by other reactive oxygen species are shedding new light on the molecular mechanisms by which chronic inflammatory processes may initiate or enhance carcinogenesis in humans.?

?A surfeit of PGE-2, free radicals, altered fat metabolism and general immunosuppression by LD may contribute to a predilection (stimulate or predispose) for oncogenesis (forming cancer). Carcinomas are not unknown in LD: melanoma, thyroid cancer, and lymphoma have been published. Free radicals, by engendering connective tissue cross-linking, could be responsible for intra-abdominal adhesions to form, and for some LD patients to appear older than their stated age, or have a haggard facial appearance.?

?At the present time, the etiology of epithelial ovarian cancer is poorly understood. It has recently been recognized that certain chronic infectious agents may contribute to carcinogenesis by inducing a state of persistent inflammation.

?Research suggests that a compromised immune system is a major contributor to the development of cancer?. Recent research has linked the presence of various infections as the trigger of cancer, for example HPV infections and cervical cancer, candida and breast cancer, and Chlamydia and Lymphoma. In these cases, infections are usually present because the immune system is compromised. Because a tumor grows into and disrupts surrounding tissue, decreased circulation to certain areas occur with provides the perfect low-oxygen environment where infections flourish. Data has shown that when the infection is treated, cancer progression stops.? Alternative Ovarian Cancer Facts & Information.

?Specific DNA sequences of Borrelia burgdorferi were identified in cutaneous lesions from 9 patients (follicle center lymphoma: 3/20; immunocytoma: 3/4; marginal zone B-cell lymphoma: 2/20; diffuse large B-cell lymphoma: 1/6). Specificity was confirmed by Southern blot hybridisation in all positive cases. We could show that Borrelia burgdorferi DNA is present in skin lesions from a small proportion of patients (18%) with various types of CBCL. Our results may have therapeutic implications. In analogy to Helicobacter pylori-associated MALT-lymphomas, which in some cases can be cured by eradication of Helicobacter pylori infection, a proportion of CBCL may be cured with antibiotic therapy against Borrelia burgdorferi. Although yet speculative, adequate antibiotic treatment for patients with primary CBCL should be considered before more aggressive therapeutic options are applied, particularly in countries where infection by Borrelia burgdorferi is endemic. PCR analysis of Borrelia burgdorferi DNA is a fast test that should be performed in all patients with CBCL to identify those who more likely could benefit from an early antibiotic treatment.?

?In addition, serious signs of liver damage, like cirrhosis or cancer, may not appear until as long as 20 years after the infection began. ?

Owing to the fact that the serologic criteria of neuroborreliosis were not fulfilled, and other symptoms (loss of consciousness) appeared, CT was done. The CT showed the presence of a tumor in the longitudinal fissure of the brain, which, after intraoperative and histopathological examination, was defined as meningioma.?Biesiada G, Kalinowska-Nowak A.

?In conclusion there appears to be a clustering of positive serology for Lyme disease Borrelias in PCBCL patients possibly related to an ethiopathogenic relationship.

The recent availability of infection models and bacterial molecular genetic techniques has fostered research on the pathogenesis of the bartonellae and has advanced our understanding of the virulence mechanisms that underlie the host-cell tropism, the subversion of host-cell functions during bacterial persistence, as well as the formation of vascular tumours by these intriguing pathogens.? Bartonella-host-cell interactions and vascular tumour formation. Dehio C. Nat Rev Microbiol. 2005 Aug;3(8):621-31.

?An analogy for the existence of these individual steps is considered in connection with the development of cancer. The transformations of eukaryotic cells occur in particular in the type IV secretion system, i.e. involving the simultaneous transmission of DNA and protein from bacterial cells to eukaryotic cells. Thus, transfected cells facilitate the indefinite growth of tissue cells and additionally produce growth factors, triggering further bacterial multiplication. The higher numbers of bacteria then produce more transfection and the cycle repeats as long as the host lives. The main limiting factor is the frequency of bacterial infection, while the secondary rate-limiting factors are the levels of transforming growth factors and factors triggering bacteria growth. CONCLUSIONS: Analogous processes are probably responsible for the tumor induction by the three different bacterial species; however, the critical points for eradication are different. The early eradication or limitation of B. henselae or H. pylori can prevent hemangiomas, stomach cancer and malignant cell proliferation. The crown gall formation by A. tumefaciens can only be avoided by prevention of the transforming activity of a single bacterial infection.? Bacterial models for tumor development. Mini-review.

Abstract
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.
