ConfocAl endomicroSCopy bAsed Diet Trial in IBS

Targeted Elimination Diet in IBS Patients Following Identification of Trigger Nutrients Using Confocal Laser Endomicroscopy

• Status: Recruiting
• Phase: N/A

• Enrollment: 65 (estimated)

• Healthy volunteers: Accepted

Summary

After a thorough baseline evaluation, IBS patients will be exposed to nutrients while undergoing confocal laser endomicroscopy (CLE). Patients presenting an acute mucosal reaction upon nutrient exposure will be instructed to exclude their respective trigger nutrient or a nutrient without mucosal reaction (=sham diet) from their diet for 4 weeks in a randomized, blinded crossover fashion. The aim of the trial is to assess the symptomatic response to the targeted diet and further elucidate mechanisms underlying the acute mucosal reactions observed in CLE upon nutrient exposure.

Conditions

• Irritable Bowel Syndrome
