Clinical trial with cyclosporin A.

Six male patients with extensive psoriasis, resistant to conventional treatment, were treated orally with low-dose Cyclosporin A (CsA) (5 mg/kg/day). One patient had generalized pustular psoriasis, three psoriatic erythroderma, and two disseminated chronic plaque psoriasis. All patients, with the exception of one, were treated for at least twelve weeks. Nearly complete remission was obtained in four cases. In one patient the response was incomplete, while treatment in one case was suspended after two weeks because of the onset of cutaneous pyogenic infections and oral candidiasis. In each case a relapse was observed with the suspension of treatment.
