Ulcer- and Cancer-Causing Bacteria Also Protects Against Asthma

In a new study, researchers say that a current campaign to wipe out the bacterium, Helicobacter pylori, may be having the unintended consequence of boosting asthma rates in kids.

A longtime resident of the human stomach, H. pylori went largely undetected until Australian scientists discovered it in 1979 and went on to show that it can cause stomach ulcers. Further work has linked it to stomach cancer. It’s now treated with antibiotics whenever detected [Science News]. But researchers say that when they studied health records of over 7,000 kids between the ages of 3 and 13, they found that children with H. pylori in their stomachs were less than half as likely to develop asthma. Those children were also less likely to suffer from eczema and hay fever.

The study, which will be published in the Journal of Infectious Diseases [subscription required] later this week, suggests that doctors embraced the campaign against H. pylori too quickly, before fully understanding the repercussions. “When humans left Africa, they had H. pylori in their stomachs. It was universal. And it’s now clear that H. pylori is disappearing. Ulcer diseases and stomach cancers are going away, but new diseases are appearing — including asthma and related disorders,” said study co-author Martin Blaser [Wired News].

Blaser says the study doesn’t prove that the bacterium itself is preventing asthma, and says they could serve as a marker for something else that happens in children’s developing bodies. “One explanation for this phenomenon has been termed the ‘hygiene hypothesis,’ which considers that humans are more prone to allergic disorders because of a lifestyle that may be too ‘clean’,” Blaser’s team wrote. The idea is the immune system doesn’t have enough work to do early in life, so it becomes hyper-responsive to inappropriate triggers, such as dust, instead [Reuters].

    New specific biological product to remedy autoimmunereactions of a streptococcal aetiology.
    V.A.Esepenok, the Doctor of Veterinary Science. MoscowState Academy of Veterinary Medicine and Biotechnology named after Dr K.I. Skryabin.
    Streptococcoci is an infectious disease of humanbeings, of all types of live-stock animals, wildlife fauna, laboratory animalsas well as of all barnyard and wildlife fowls, bees, fish and the reptiles,which is induced by gram-positive bacteria of streptococcosus. Wide bacteriacarriage rate among attendants and service personnel fosters the infection ofanimals and vice versa, due to the fact that haemolytic streptococci areidentical for all the chordates.
    The disease affects localized sectors (abscess), specifictissues, organs, body systems as well as all the organism leading to a lethaltermination.
    Pathogenic streptococci are complex biological substanceswith external and internal enzymes which in the course of their biological lifehave adapted to elude from phagocytes, to avoid system of complement, to form mutantsin a parent cell causing disease of the host even when there are no signs ofimmunodeficiency.
    The aetiological significance of streptococci in pathologyof animals and human beings is being underestimated, as they are fastidious tonutrient mediums and certain skills for their extraction from pathologicalmaterial are required. Immune attack of autogenous tissues of the host of thepathogenic agent germinates usually without its excretion from the diseasedorganism. Internal aggressines of pathogenic streptococci damage tissues of thehost and ensure penetration of streptococci (disease progress i.e. zymosis) aswell as of other microorganisms, i.e. provoking a number of infectious diseaseswhich are not listed in R. Koch’s triad.
    Having studied the biology of pathogenic streptococciand disease progress during their penetration into a susceptible organism, wehave prepared a toxoid-vaccine STREPTOEVAK on the basis of biological polymers(1).
    The biological product in reference is harmless and arectogenious,possesses antitoxic and preventive effects against haemolytic streptococci ofanimals and birds. The above has been proved in experimental and workingconditions on thousands various kinds of susceptible animals (2).
    At present practicing medical experts all over the worldhave nor secure tools nor preventive remedy for streptococcosis of humanbeings. According to L.V.Lvova (2000)(3), in case of streptococcosis disease, unfortunately, there is no medicalproduct able to save human beings from glomerulonephritis. Even such radicaltreatment as transplantation does not ensure success for up to 100%, because inmost of the cases glomerulonephritis germinates again in the replaced kidney. Scientistsof the State Centre of Science of Virology and Biotechnology of the RussianFederation called the VECTOR (2006) have put forward a hypothesis: «Aetiology of oncological and cardiovascular diseases » where theyconvincingly predict etiological significance of streptococci. We theoreticallyunderstand and support medical scientists, and practically we are working for confirminga solvency of their assumptions.
    Autoimmune diseases of eyesight constitute a seriousproblem of veterinary medicine due to the fact that it is often that suchdiseases lead to dangerous, and sometimes even irreversible changes in eyetissue. The keratoconjunctivitis sicca (when the inflammation is dueto dryness), which leads,as its consequence, to the deep parenchymatous ulcerous keratitis with ulcersthat remain unhealed for rather extended period of time constitute a seriousproblem because apart from representing some interrelated processes they are alsothe linking components of pathogenesis thus provoking the blindness of animals.
    The toxoid-vaccine of STREPTOEVAK is successfully applied to the treatment ofcats with an initial stage of corneal sequestrum. The basic diagnostic criteriafor this product application are: blepharospasmus, lachrymation, third eyelidprolapse. When applying the solution offluorescein against the affected cornea an intensive green coloring of all erosivesurface appears. Streptoevak is normally applied in a dose of 0.5 mlintramuscularly with an interval of 15-20 days up to three applications. Together with Streptoevak the Actovegin isnormally prescribed which is an eye jelly, as well as some antimicrobial agents.When the treatment starts without delay a restoration of integrity of the corneais achieved, and further impregnation of the denuded stroma with epinephrine oftear does not occur as well as pigmentary focus formation is being avoided .
    Especially this biological product is effective (thatproves its high specificity) in the cases of transformation of fibroblast-likecells on mucous tunic of eyes of dogs (the third eyesight). Enclosed photos show animals before treatment(1.2) and those after treatment (3.4). The course of treatment is just four (4)injections in accordance with instructions for application of toxiod-vaccine product.For the first time in the world the results of treatment of cats and dogs curingstreptococcosus disease aftereffects have been achieved without surgeryoperations.
    Studying the influence of STREPTOEVAK over the growthof an intertwined liver tumor (hepatocellular carcinoma) of mice was our next stageof work. The experiment has been made onmice RUVR. For the hypodermic transplantation ithas been used the passage number 16 of the liver tumor strain on experiment animals,which was obtained in Russian Oncological Scientific Center named afterN.N.Blokhin working under the RussianAcademy of Medical Science. The mice have been vaccinated twice with aninterval of 12 days by intraperitoneal introduction in doses of 0.1 and 0.3 mlrespectively. Transplant subinoculationof the tumor has been made after 7 days following the last vaccination. Thecontrol of effects has been made comparing the results against non-vaccinatedmice having subinoculated tumors. Effects of vaccination have been evaluated bythe periods between the first tumor nodes occur and tumor nodes in progress ata later stage as well as when the tumor growth slows down and finallyevaluating the changes in life expectancy. The first nodes in the vaccinatedtissue of vaccinated mice have appeared a little bit later (the percentage oftime increase was equal to 5%), however, the difference between the experimentgroup and the control one were not very significant from statistics point ofview. The average volume of tumor nodes among the vaccinated mice was less,than among non-vaccinated mice. Significant differences were registered in 8 outof 11 measurements made during the experiment. Among the vaccinated mice some decrease inaverage life expectancy (8 %) has been registered, however, the differences inreference were not significant from statistics point of view as compared with non-vaccinated animalsresults.
    Analyzing the received positive results on cats anddogs (more than 100 animals), and also on laboratory animals it is possible to makea confident conclusion that toxoid-vaccine STREPTOEVAK is a specific medicalbiological product which enables to achievethe required effects in cases of autoimmune reactions of streptococcalaetiology.
