Probiotics and urea test ?

[onetime]

Good day,

Thanks a lot for all your help.

I had been testing positive after an endoscopy. I took the antibiotics cure. Then, I gest tested with the urea test the result came négative.

My question is that at the same time, I was taking yeast : saccharomyces boulardii. Is it probiotics ? Can it alterate the urea tast ?

Thanks a lot !

My guess is no, it wont affect the breath test. Reason is because it probably cannot survive long in the stomach anyway. However, it will be interesting to find out how negative is your negative breath test. I would be suspicious if the breath test result is at the border line.

The result was <1

Yet, why is it said thant probiotics can make fake negative ? (I am curious)

It depends on the nature of the probiotics. Some probiotics neutralize the acid and acid is one of the key ingredient for Urea breath test to work.

Some probiotics actually kill H. pylori. But they dont kill H. pylori clean enough. So have a very low concentration of H. pylori, the urea breath test is giving low signal and leads to false negative.

Saccharomyces boulardii is in one group that you mentioned ?

1< is a good result on Heli Kit, no ?

I will get tested again and will let you know.

Thank you members of the forum

sorry, I am not familiar with Saccharomyces boulardii. however, I found these articles about it.

http://www.ncbi.nlm.nih.gov/pubmed/17669103

S. boulardii improved anti-H. pylori antibiotherapy-associated diarrhea, epigastric discomfort, and treatment tolerability. In addition, S. boulardii supplement decreased post-treatment dyspepsia symptoms independent of H. pylori status. However, S. boulardii had no significant affect on the rate of H. pylori eradication.

Several clinical trials and experimental studies displayed the role of S. boulardii as a good biotherapeutic agent allowing to prevent and/or treat several gastrointestinal diseases. S. boulardii mediates effects which resemble the protective effects of the normal healthy gut flora. Although the administration of S. boulardii can be associated with fungemia, no adverse effects were observed in any of the clinical trials. Caution should be taken in patients with risk factors for adverse events, such as immunocompromised patients. Larger prospective, placebo controlled clinical trials could elucidate the mechanisms of action of the yeast and suggest new therapeutic applications.
