The efficacy and safety of adding the probiotic Saccharomyces boulardiito standard triple therapy for eradication of Helicobacter pylori; A randomized controlled trial

Evaluating the efficacy and safety of adding the probiotic Saccharomyces boulardiito standard triple therapy for eradication of Helicobacter pylori.Methods and materials: In this randomized controlled trial we evaluated 160 adult patients with biopsy confirmed H.Pylori infection referred to gastroenterology ward of Taleghani hospital. The patients were randomized into two treatment regimens: patients in group A (n=80) were given amoxicillin (1000 mg, b.i.d), clarithromycin (500 mg, b.i.d), omeprazole (20 mg, b.i.d) and probiotic of saccaromyces boularidi (Yomogi) (250 mg, b.i.d) for 14 days, moreover patients in group B (n=80) were given amoxicillin (1000 mg, b.i.d), clarithromycin (500 mg b.i.d) and omeprazole (20 mg,b.i.d) for 14 days. 160 patients (66 male 41.25%, 94female 58.75%) with the mean age of 47.1±11.4 years were evaluated. The success rate for H. pylori eradication in group A was higher 75(87.5%) than group B 65 (81.2%), but the difference between two groups was not significant (p=0.350). Moreover, in case group side effects as nausea, diarrhea, abdominal discomfort and bloating were significantly lower than control group in first and second weeks. The result of this study showed that saccaromyces boularidi decreased the adverse effects associated with H.pylori therapy but did not significantly decrease the eradication rate of H.pylori.
