Longitudinal Atopic Dermatitis Control in Children

In a cohort study that evaluated longitudinal disease control and persistence with respect to atopic dermatitis (AD) onset age, early-, mid-, and late-onset pediatric AD appeared to be clinically distinct subtypes of the disease. The study was performed using the Pediatric Eczema Elective Registry, a prospective observational cohort of individuals with childhood-onset AD. AD control and persistence were assessed biannually for up to 10 years. Researchers found:

  • 8,015 participants with 41,934 person-years of follow-up were included.
  • In longitudinal analyses, older AD onset age was associated with better disease control and less persistent AD.
  • Differences in AD control and persistence among early-, mid-, and late-onset AD were most pronounced from early adolescence onward.
