Efficacy and Safety of Saccharomyces Boulardii in the Treatment of Small Intestinal Bacterial Overgrowth

Efficacy and Safety of Saccharomyces Boulardii CNCM I-745 in the Treatment of Small Intestinal Bacterial Overgrowth in Patients Suffering From Irritable Bowel Syndrome With Diarrhea

Non-constipated irritable bowel syndrome is a common disorder that may be related to small intestinal bacterial overgrowth. Saccharomyces boulardii CNCM I-745 is a probiotic yeast that has proven efficacy for the treatment of acute gastroenteritis and antibiotic-associated diarrhea. However, its efficacy for the treatment of diarrhea-predominant irritable bowel syndrome with small intestinal bacterial overgrowth has not been assessed. Hence, an exploratory randomized, open label trial comparing the efficacy and safety of Saccharomyes boulardii CNCM I-745 plus diet administration versus diet administration only for 15 days among adult patients with the aforementioned condition was conducted.
