The overall risk for acne is comparable for adults with AD and controls, according to a study published in the Journal of the European Academy of Dermatology and Venereology. Jacob P. Thyssen, MD, PhD, and colleagues examined the prevalence, incidence, and risk for acne in adolescents and adults with AD in a matched cohort study involving 6,600 adults with AD and 66,000 controls. The 12-month prevalence rates for acne were 3.7% and 3.9% in the general population and among patients with AD, respectively. Patients with AD aged 12-18 had the highest incidence rate for acne, and the incidence rate was slightly higher in women with AD than in men. In patients with AD, the overall risk was similar to that of the general population (HR, 0.96; 95% CI, 0.88-1.06), but patients with AD had a reduced risk for being treated for severe acne (HR, 0.59; 95% CI, 0.47-0.73), which was driven by adolescents and young adults.
