Brief Summary

This study aims at evaluating efficacy and safety of Saccharomyces boulardii combined with bismuth-containing quadruple Therapy versus bismuth-containing quadruple Therapy(bismuth#esomeprazole#tetracycline and furazolidone) in H. pylori rescue therapy. It is hypothesized that Saccharomyces boulardii combined with bismuth-containing quadruple Therapy is superior to bismuth-containing quadruple Therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. At week 6 follow-up visits, a urea breath test#rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.

Detailed Description

The study will include three phases: screening, treatment and follow-up. Screening: this phase will last a maximum of 14 days and subjects eligibility will be evaluated after signing informed consent. One of urea breath test#rapid urease test or helicobacter pylori stool antigen test will be performed in addition to the baseline routine evaluations.

Treatment: Subjects are randomly assigned to treatment and will be treated for 14 days. A randomization visit will take place on Day 0 and an end-of-treatment visit will take place between day 14 and 16.

Follow-up: includes one visits. Approximately 28 days after the end of treatment. Eradication of H. Pylori will be confirmed by one of urea breath test#rapid urease test or helicobacter pylori stool antigen test.
