Key clinical point: Children and adolescents with atopic dermatitis (AD) are at an increased risk of developing juvenile idiopathic arthritis (JIA).
Major finding: Patients with AD vs control individuals had an increased risk for JIA (adjusted odds ratio [aOR] 1.58; 95% CI 1.41-1.77), especially for psoriatic JIA (aOR 2.75; 95% CI 1.64-4.60).
Study details: This population-based register study included 70,584 patients with AD aged <18 years at the time of the first AD diagnosis and 270,783 age- and sex-matched control individuals without AD.
Disclosures: This study did not receive any funding. Some authors declared serving as investigators for or receiving educational grants, speaker honoraria, or consultation honoraria from various organizations.
