Abstract
BACKGROUND: Atopic dermatitis (AD) is a chronic relapsing skin disease. Several investigations concerning the long-term prognosis of AD among children and teenagers have been performed but there are only few data among adults. OBJECTIVES: To investigate the prognosis and prognostic factors in adult patients with AD by a long-term follow-up (25-38 years). The prognostic factors were defined as those factors of importance for the persistence of AD. PATIENTS AND METHODS: A follow-up questionnaire was sent in November/December 1998 to 922 AD patients examined in our outpatient clinic between 1960 and 1973 among 1366 registered patients with AD. The patients were aged 20 years or older when they visited the clinic and 45 years or older when they answered the follow-up questionnaire. RESULTS: The response rate was 90.4%. The age range at the time of follow-up was 45-86 years (mean 55 years). Of the 833 patients who responded, 59% reported AD at some time during the last 12 months, which we defined as persistent AD. The mean value of clearance rate per person-years was 18%. One of the most important factors associated with persistence of AD was a head and neck dermatitis with or without other AD locations at the time of examination according to the old patient records. CONCLUSIONS: This study showed that the majority of adults with AD still had AD when they became older. This applies particularly if negative prognostic factors existed.
