ABSTRACT
PURPOSE: Severe atopic dermatitis is a condition that can seriously affect the quality of life. This study was performed to evaluate the efficacy and side effect of cyclosporin A treatment in children. METHODS: Nine children(male 7, female 2) with severe atopic dermatitis resistant to conventional therapy and/or significant suffering and disability. The initial dose of cyclosporin A was 2.1-5.2 mg/kg/day and the duration of treatment was 4-6 weeks. The severity and extent of atopic dermatitis were evaluated with modified criteria of Hanifin and Rajka, at 0, 2, 4 and 6th week and after cessation of cyclosporin, at 10th week. Total clinical score was calculated as the average of both extent and severity score. RESULTS: There are significant improvement in both of the symptom severity and the extent of atopic dermatitis. The mean severity and extent scores were 92% and 88% before treatment and 28% and 34% after 6 weeks' treatment. The overall change of the total clinical score was 59% of decrease. Two patients had to stop the drug after 4 weeks of treatment because of severe abdominal pain, especially at night. After stopping the drug, at the 10th weeks' evaluation, 3 patients showed symptomatic exacervations but 6 patients maintain their improved state only with conventional treatment. CONCLUSION : Despite the side effect, cyclosporin A gave a rapid clinical response to severe refractory atopic dermatitis in children.
