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.

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.

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.?

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.

?Most remarkably, bartonellae can trigger massive proliferation of endothelial cells, leading to vascular tumour formation. 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.?

?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.

Neuroborrelioosi on yksi Borrelioosin kroonisista ilmenemismuodoista. Oireen aiheuttaa borrelia burgdorferi spirokeetta. Keskushermosto-ongelma voi esiintyä Borrelioosin toisessa ja kolmannessa vaiheessa. Toisessa vaiheessa voi esiintyä aivokalvontulehduksia ja esim radikuliitteja l. hermojuuritulehduksia. Kolmannessa eli kroonisessa vaiheessa voi esiintyä useiden eri sairauksien kaltaisia oireita kuten MS-oireita, aivokasvaimia, aivotulehduksia, psykiatrisia oireita, myelopatiaa l. luuydin-, selkäydinsairauden, aivojen verisuonitulehduksia jne.
10-vuotiaalla lapsella havaittiin borrelia-bakteerin aiheuttama neuroborrelioosi. Sen seurauksena lapsella ilmeni kallonsisäistä kudosmassaa.

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.
