Task: Answer Verification
Input (English): Question: Does confocal endomicroscopy show food-associated changes in the intestinal mucosa of patients with irritable bowel syndrome?
Answer: Based on CLE analysis of IBS patients with a suspected food intolerance, exposure to candidate food antigens caused immediate breaks, increased intervillous spaces, and increased IELs in the intestinal mucosa. These changes are associated with patient responses to exclusion diets. Registered at clinicaltrials.gov (registration number: NCT01692613).
Output (English): yes
