ORIGINAL ARTICLE Inflammatory Bowel Disease in Patients with Celiac Disease

between celiac disease and inflammatory bowel disease (IBD); how-ever, there is no current data assessing this association. We therefore studied the occurrence of these conditions in a cohort of patients with celiac disease seen at a referral center. Methods: A database of patients with celiac disease seen between 1981 and 2002 was analyzed. Only biopsy-proven adults were in-cluded. Patients who had endoscopic and pathologic evidence of IBD were identified, and their pathology was reviewed. Age- and sex-adjusted prevalence rate ratios were determined by comparing results with population-based prevalence data. Results: Among 455 patients with celiac disease, IBD was iden-tified in 10 (5 had ulcerative colitis and 5 had Crohn’s disease). This represented an age- and sex-adjusted prevalence rate ratio for ul-cerative colitis of 3.56 (95 % confidence interval, 1.48–8.56) and for Crohn’s disease of 8.49 (95 % confidence interval, 3.53–20.42)
