Key clinical point: Patients with alopecia areata (AA) have an increased risk for atopic dermatitis (AD) and vice versa.
Major finding: Patients with AA vs control individuals had a significantly higher risk of developing AD (adjusted odds ratio [aOR] 4.42; P < .001). Reciprocally, patients with AD vs control individuals also had a significantly higher risk of developing AA (aOR 5.08; P < .001).
Study details: Findings are from a nested case-control study including 984 patients with AA from the All of Us database (USA), who were matched with 3936 control individuals without AA using nearest neighbor propensity-score matching.
Disclosures: This study did not disclose any funding source. E Guttman-Yassky and B Ungar declared receiving institutional grants from, serving as consultants for, or having other ties with various sources. The other authors declared no conflicts of interest.
