Cyclosporine in systemic sclerosis. results of a forty‐eight–week open safety study in ten patients

Abstract
Objective. To evaluate safety and efficacy of cyclosporin A (CSA) treatment in systemic sclerosis (SSc). Methods. Ten patients with ⩽60 months of SSc were entered into a 48‐week open study of CSA. Patients with hypertension or azotemia were excluded. Concurrent use of nonsteroidal antiinflammatory agents or diuretics was not permitted. The extent of cutaneous and visceral involvement at 48 weeks and at study entry were compared. Results. Adverse reactions (especially nephrotoxicity) were frequent, usually transient, often dose‐limiting, and usually associated with CSA doses ⩾3–4 mg/kg/day. Skin thickening decreased significantly (P Conclusion. CSA should undergo blinded controlled study in patients with SSc.
