[Probiotic therapy of the irritable bowel syndrome]

The irritable bowel syndrome (IBS) is among the most common disorders in gastroenterological practice with a prevalence of approx. 12 % in Germany, and it is characterized by abdominal pain or discomfort, altered stool frequency and consistency, and meteorism and bloating. There is currently no agreement between those seeing patients with IBS (general practitioner, gastroenterologist, psychosomatics) on the criteria for clinical diagnosis. Metaanalyses of treatment studies in IBS have shown that probiotics have a high clinical efficacy in IBS, especially since development of novel pharmaceutical compounds have not reached the market or have been withdrawn. In addition to the actual status of probiotic efficacy in IBS studies conducted worldwide, we present 3 German clinical studies with probiotic E.COLI preparations that have proven their efficacy in IBS in adults and in children.
