Crohn’s disease (CD) is one of the two main entities of idiopathic inflammatory bowel disease (IBD). In the second funding phase, the tandem will specify the diet-induced changes in the intestinal microbiome for therapeutic efficacy of exclusive enteral nutrition (EEN) in pediatric Crohn’s disease. EEN-associated signatures will be characterized using the combined approach of continuous culture, gnotobiotic mice and pig models. In this context, the role of dietary fiber in provoking disease relapse will be evaluated. Longitudinal bacterial- and metabolite-profiling of treatment responsive and refractory patients will be implemented to identify functionally relevant microbiome targets in response to EEN, leading to the development of protective synthetic bacterial consortia. The perspective of this project is to develop a microbiome-based maintenance therapy for pediatric CD patients.
