Summary: Involvement of pathogenic or potentially pathogenic bacteria in the pathogenesis of inflammatory bowel disease has long been suggested because, among other reasons, the inflammatory response resembles that in infectious bowel diseases.Elevated antibody levels to pathogen antigens and a changed metabolic activity of the intestinal microflora have been detected in patients with Crohn's disease. Several studies have revealed a possible etiologic link between intestinal microorganisms and inflammatory bowel disease…
Promising results came from the present pilot study in which the nonpathogenic Escherichia coli strain Nissle 1917 was tested for efficacy and tolerance in maintaining remission in patients with colonic Crohn's disease. Application of the physiologic bacteria reduced the risk for relapse and minimized the need for glucocorticoids. Therefore we are convinced that in Crohn's disease parts of the intestinal microflora, including the host's immune response toward indigenous flora or an impairment of the gut flora's metabolic activity are involved in the development or at least in the onset of relapse from remissive of colonic Crohn's disease.
However, more data are necessary to prove the benefit of E. coli strain Nissle 1917 as a new therapy to maintain remission of colonic Crohn's disease.
