A Lyophilized Form of Saccharomyces Boulardii Enhances the Helicobacter pylori Eradication Rates of Omeprazole-Triple Therapy in Patients With Peptic Ulcer Disease or Functional Dyspepsia
Background: Saccharomyces boulardii prevents antibiotic-induced diarrhea and exerts anti-H.pylori effects in vitro and in vivo.
Aim: To assess whether S. boulardii enhances the efficacy of classic triple therapy in eradicating H. pylori.
Methods: Seventy patients with peptic ulcer or functional dyspepsia according to Rome III criteria and H. pylori infection were treated with omeprazole 20 mg bid, clarithromycin 500 mg bid and amoxicillin 1 g bid for 14 days. A total of 36 out of 70 (51%) patients were randomized to S. boulardii [Ultralevure®, two capsules tid for 14 days (group A) and 34 (49%) on no intervention (group B). H. pylori eradication was assessed by a 13C-Urea Breath Test.
Results: At baseline there were no significant differences between the two groups in any patient or disease characteristics. H. pylori was eradicated in 30/36 (83.4%) patients in group A vs 20/34 (58.8%) in group B (P=0.034, 95% CI 4.4% to 43.6%). Seven patients in group B (20.6%) and 1 patient in group A stopped treatment because of diarrhea (95% CI 3.3% to 32.7%, P=0.026). Multi-factorial analysis did not reveal any patient or disease related parameter linked to treatment outcome except for the use of the probiotic.Conclusion: S. boulardii enhanced the effect of classic triple therapy mainly by preventing antibiotic- and/or proton pump inhibitor-induced diarrhea.
