Treatment for Helicobacter Pylori

Treatment (General)


If you are found to have Helicobacter pylori infection, you may wish to have antibiotic treatment of some kind. Treatment of Helicobacter pylori is usually simple & straight forward. However, occasional patients need repeated endoscopies, biopsies,breath tests and several courses of treatment with different antibiotic combinations..

After treatment of H. pylori , it is necessary to repeat one of these tests to see if the germ has been killed or eradicated for good. Only breath tests or endoscopy with biopsy can be used to prove that the bacterium has been eradicated. The blood tests *(serology ) is not suitable to monitor H.pylori eradication because antibodies to H.pylori may remain positive for months or even years after successfully killing the H. pylori .

 

Risks of H. Pylori Therapy


There is a small risk associated with taking bismuth drugs (for example, Pepto-Bismol or De-Nol). They may temporarily cause grey staining of the teeth and mouth and can cause constipation, diarrhoea, and blackening of the stools. All antibiotics have a small risk of an allergic reaction. The antibiotics we recommend are called amoxycillin, clarithromycin, tetracycline and metronidazole. If your H. pylori infection is difficult to cure, we may suggest that you take different antibiotics or higher doses in order to treat it. If you have ever had a reaction to antibiotics, you should tell your doctor (for example, penicillin allergy). The antibiotics are commonly used and are safe, but they may cause a bad taste in the mouth (clarithromycin [clari], metronidazole [met]), dizziness , tingling [met], stomach upset, diarrhoea, and, very rarely, fatal reactions (as may occur with all antibiotics). If you are given metronidazole (trade name in Australia is �Flagyl�), you should not drink alcohol while taking the drug because an unpleasant reaction may occur (flushing, headaches, and nausea). Flagyl (metronidazole) should not be used in pregnancy.

Treatment Rules


Acid lowering drugs such as ranitidine, cimetidine, famotidine, omeprazole, pantoprazole and lansoprazole are generally safe, but discuss them with your doctor and read the package for more information. Only combinations of antibiotics with the above medications have been shown to eradicate H.pylori . Some patients have developed transient Candida (i.e.yeast )infection after antibiotic use. If you are concerned about this discuss it with your doctor and take an antifungal agent if appropriate.

If you are pregnant or likely to become so, you should tell your doctor and he/she may decide not to treat your H. Pylori infection or to use a special combination of antibiotic therapy.

Antibiotic therapy should not be given unless a diagnostic test for H.pylori has been performed and a positive result is obtained. The absence of H.pylori in peptic ulcer is a diagnostic pointer to an unusual and perhaps more serious etiology. There is no justification for treating patients longer than 14 days. Cure rates have been less with shorter therapies but longer therapies have not been shown to result in greater cure rates. If 14 day therapy fails, the bacterium is probably resistant to that antibiotic combination and future therapy may need to be guided by antimicrobial sensitivity testing of the cultured organism from that particular patient.

If therapy fails, your doctor should try not to use the same combination of antibiotics again . H.pylori easily becomes resistant to metronidazole and clarithromycin so these agents should not be used twice unless antibiotic sensitivity data is available to support their continued use. After therapy, avoid antimicrobial agents for 4 weeks and omeprazole for one week before doing a diagnostic test (biopsy for histology and CLOtest , or a urea breath test either C14 or C13 ) to confirm eradication.

Resistant Infections


If two therapies fail (and H.pylori still persists as indicated by by breath test or endoscopy & biopsy analysis) then expert advice is required. You may have antibiotic resistant H.pylori. .

Your doctor may wish to perform endoscopy and biopsy with culture to check the antibiotic susceptibilities./ sensitivities of the H.pylori strain you have. . Knowing the antibiotic sensitivity profile of the H.pylori strain you have been infected with the doctor can then treat you with the most appropriate antibiotic combination that will get rid of the H.pylori you have..

 

Homeopathic Remedies


There is no data available to support their use. It seems that if homeopathic remedies worked, the makers would perform clinical trials to prove it and then have them widely available under prescription. Since most if not all manufacturers of homeopathic and naturopathic remedies for H.pylori have not conducted requisite clinical trials ( which are very expensive to conduct) then we can assume that the manufacturers don't really believe that their remedies work at all! So be vary of such remedies.

We recommend that you take the real medically proven therapies described above. Interestingly, some compounds used as natural therapies do suppress (but not cure) Helicobacter pylori . An example is lactobacilli found in yoghurt)!

Basically, HP is tough to eradicate if you don't do it "by the book".

 

Vaccines


Vaccines are being tested in animals and humans. Despite many clinical trials, it is very early days yet. At the present point in time there are no vaccines for the prevention of H. pylori
