EurekAlert! -- CINCINNATI – March 23, 2009 – A review by researchers at Northwestern University (Chicago, IL.) and University of Michigan (Ann Arbor, MI) of the utility of probiotics in the treatment of Irritable Bowel Syndrome (IBS) found that Bifidobacterium infantis 35624 was the only probiotic strain out of 13 different individual strains or preparations reviewed to significantly improve symptoms of IBS, including abdominal pain, bloating and bowel movement difficulty. Bifidobacterium infantis 35624 is marketed as Bifantis® and can be found in a daily probiotic supplement by Procter & Gamble. The researchers reviewed 16 random-controlled-studies, evaluating the efficacy, safety and tolerability of probiotics in the treatment of IBS. With the exception of the Bifidobacterium infantis 35624 studies, researchers found the other trials did not use an appropriate study design and did not adequately report adverse events. The article was published on the American Journal of Gastroenterology website in advance of appearing in the publication’s April 2009 issue1.
