Atopic dermatitis in adults: does it disappear with age?

Abstract

There is limited knowledge of the prognosis in adult atopic dermatitis. We previously published a long-term follow-up questionnaire study of adults with atopic dermatitis. This study is a clinical examination of 79 adults (mean age 57 years) recruited 3 years after that study. Most patients (68%) still reported that they had atopic dermatitis and 53% had ongoing eczema at examination, mainly located on the head and neck. Severity was mainly mild to moderate, but 12% had severe atopic dermatitis. IgE antibodies to Malassezia (m70) were more common in patients with ongoing atopic dermatitis, while positive Malassezia culture was seen mainly in patients with no ongoing atopic dermatitis. M. obtusa and M. globosa were the most commonly cultured Malassezia species. In conclusion, considering increased prevalence of atopic dermatitis in children in recent decades and the fact that atopic dermatitis in most adults continues for many years, we should expect to see more adults with atopic dermatitis in the future.
