Relapse rates in moderately severe chronic psoriasis treated with cyclosporin A

Seventeen patients with chronic psoriasis were given cyclosporin A (CsA) 5 mg/kg per day. Twelve patients cleared within 3 months and their relapse rate, 41% at 6 months, was not significantly different from that previously reported with dithranol or PUVA. This pilot study also suggests that continuing CsA for up to 4 weeks after clinical clearance confers no advantage with regard to relapse. Significant adverse effects on renal function and blood pressure did not occur.
