Atopic dermatitis positively linked with the risk for acne

Key clinical point: The overall risk for hospital-diagnosed acne is significantly higher in patients with atopic dermatitis (AD), highlighting the need to address comorbid skin diseases simultaneously along with the management of AD.

Major finding: Patients with AD vs control individuals had a 3-fold higher overall risk for hospital-diagnosed acne at ≤18 years (adjusted odds ratio [aOR] 3.44; 95% CI 3.13-3.78) and ≤30 years (aOR 3.15; 95% CI 2.90-3.42) of age.

Study details: The data come from a retrospective registry study that included 70,584 patients with AD aged ≤18 years at the time of their first AD diagnosis and 270,783 matched control individuals without AD.
