Key clinical point : Patients with atopic dermatitis (AD) have a 1.28-fold increased risk of developing rheumatoid arthritis (RA) but patients with RA do not have an increased risk of developing AD.
Major finding: Patients with AD had a significantly increased risk of developing RA (odds ratio [OR] 1.28; P < .001). However, the risk of developing AD in patients with RA was not significant (OR 1.10; P = .52).
Study details: The data come from a systematic review and meta-analysis of nine studies that investigated the association between AD and RA.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
