Dietary Therapies Induce Rapid Response and Remission in Pediatric Patients With Active Crohn's Disease.

Background & Aims: Dietary therapies based on exclusion of usual dietary elements induce remission in children with Crohn's disease (CD), whereas re-exposure induces rebound inflammation. We investigated whether a short trial of dietary therapy, to identify patients with and without a rapid response or remission on the diet (DiRe), can be used to predict success or failure of long-term dietary therapy.

Methods: We collected data from the multicenter randomized trial of the CD exclusion diet (CDED).
