NCT00795496 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 50

No results posted yet for this study

Summary

The investigators will contact 64 patients with atopic dermatitis (AD) who participated in a long-term tacrolimus ointment trial in Helsinki 10 years ago, and ask them to participate in this follow-up study. The investigators will do the same tests as 10 years ago, i.e. bronchial hyperreactivity, skin prick tests, serum-IgE, Mantoux-test (2 TU), and questionnaires about asthma and allergic rhinitis symptoms. The investigators also collect data about their AD medication during the last 10 years.

The investigators hypothesis is that when the skin condition improves in patients with AD the brochial hyperreactivity improves. The investigators also want to study whether different treatments play a role in the development or resolution of bronchial hyperreactivity.

Conditions
