    Abstract:
    BACKGROUND: Conventional therapy can result in remission in mild-moderate pediatric Crohn's disease (CD). However, some patients experience loss of response to biological drugs despite increased dosage. METHODS: We planned to determine that CD exclusion diet plus partial enteral nutrition offers additional benefits in asymptomatic children with CD having elevated fecal calprotectin. A randomized, open-label, pilot, controlled interventional study was conducted in children with CD while on medical treatment and elevated fecal calprotectin on routine testing. Patients continued their medications and were randomized into a group that received CD exclusion diet plus partial enteral nutrition for 12 weeks and one that continued a regular diet. RESULTS: Twenty-one patients participated: 11 received CD exclusion diet plus partial enteral nutrition and 10, regular diet. Median fecal calprotectin in the CD exclusion diet plus partial enteral nutrition decreased in 9/11 to 50% of baseline, remaining practically unchanged in the regular diet, except for two patients (p = 0.005). Body mass index z-score increased in the CD exclusion diet plus partial enteral nutrition. Only 1/11 patients in the CD exclusion diet plus partial enteral nutrition group, while 4/10 in the regular diet, experienced clinical relapse (p = 0.149). Only one patient in the CD exclusion diet plus partial enteral nutrition, while eight in the regular diet, were considered to need their biologic treatment intensified (p = 0.005); 2/11 in the CD exclusion diet plus partial enteral nutrition had the dose or frequency of the biologic reduced vs. none (0/10) in the regular diet group. The short Pediatric Crohn's Disease Activity Index and anthropometry showed no significant changes in either group. CONCLUSIONS: Diet therapy could be a useful addition to medications in children with CD in apparent remission, but elevated fecal calprotectin. TRIAL REGISTRATION: Clinical trial number: NCT05034458.
