Phase IV Study Comparing a Nutritional Anti-Inflammatory Treatment to Steroids for Pediatric Crohn's Disease - the Molecular Basis

The precise and exact cause of Crohn's disease (CD) remains still unknown. However, recent data point out to an inappropriate and exaggerated inflammatory response of the intestinal mucosal immune system toward intestinal commensal flora as initial trigger. Several strategies were developed in the treatment of active CD. Anti-inflammatory drugs such as steroids proved to be very helpful in the induction of a primary remission as is the use of exclusive enteral nutrition. Besides a long standing experience with EN in the management of CD in several centres, the mode of action and the molecular mechanisms of a specific EN, such as Modulen IBD ® remain still unknown. The ultimate aim of this study is to compare the efficacy of Modulen IBD ® in inducing remission compared to steroids with a detailed analysis of the mucosal repair and anti-bacterial defence mechanisms within the inflamed intestinal mucosa and the composition of the commensal flora before and during therapy. This approach may help to elucidate the interaction between the intestinal mucosa and the commensal flora during the onset of CD and induction of remission.
