Long-term follow-up of eczema patients treated with cyclosporine.

Cyclosporine is efficacious in short-term treatment of various eczematous disorders. In a follow-up study we have evaluated the long-term efficacy of cyclosporine in 75 patients, who in previous studies had been treated with cyclosporine for chronic actinic dermatitis (6 patients), atopic dermatitis (42 patients) and chronic hand eczema (27 patients), 4, 2 and 1 year after the initial treatment, respectively. Three out of 6 patients with chronic actinic dermatitis showed long-term efficacy. Two years after the initial treatment with cyclosporine (5 mg/kg/day for 1-2 treatment periods of 6 weeks) for atopic dermatitis the mean disease activity was significantly lower compared to baseline (58% decrease), and compared to the time of treatment stop no significant change had occurred. Of 37 evaluable patients 35 were still in remission. One year after the initial treatment with cyclosporine (3 mg/kg/day for 6 weeks) for chronic hand eczema the mean disease activity was significantly lower than at baseline (54% decrease), and compared to the time of treatment stop no significant change had occurred. Of 27 evaluable patients 21 patients were still in remission. The study suggests that long-term remissions are possible in eczematous diseases treated with cyclosporine, even for a relatively short treatment period. It must be stressed, however, that we did not have control groups for any of the studied patient groups.
