Key clinical point: Children and adults with atopic dermatitis (AD) have a significantly increased risk of developing inflammatory bowel disease (IBD), including Crohn’s disease (CD).
Major finding: Children with vs without AD had a significantly higher risk for IBD (adjusted HR [aHR] 1.44; 95% CI 1.31-1.58) and CD (aHR 1.74; 95% CI 1.54-1.97), but the risk for ulcerative colitis (UC; aHR 1.65; 95% CI 1.02-2.67) was higher only in children with severe AD. Adults with vs without AD had a significantly increased risk for IBD (aHR 1.34; 95% CI 1.27-1.40), CD (aHR 1.36; 95% CI 1.26-1.47), and UC (aHR 1.32; 95% CI 1.24-1.41).
Study details: This population-based cohort study matched children (n = 409,431; age < 18 years) and adults (n = 625,083) with AD with control children (n = 1,809,029) and adults (n = 2,678,888) without AD, respectively.
Disclosures: This study was supported by a contract from Pfizer Inc. Five authors declared receiving grants, personal fees, and fellowship funding from various sources, including Pfizer Inc.
