THE ROLE OF CYCLOSPORINE-A IN THE TREATMENT OF PEMPHIGUS ERYTHEMATOSUS

Steroids are effective in the autoimmune bullous disease pemphigus; however, treatment may be difficult to sustain because of severe side effects. Cyclosporine A acts mainly on helper/inducer T lymphocytes and has few side effects at low doses. We report three patients with pemphigus erythematosus who had a relapse while receiving the maintenance dose of steroid therapy. All patients who were treated with both cyclosporine A (5 mg/kg/d) and prednisone (1 mg/kg/d) responded remarkably well to combined therapy. After clearing, prednisone was discontinued and cyclosporine A was reduced to 2 to 3 mg/kg/d. With this treatment, all patients have been virtually free of symptoms, have remained well, and have had normal laboratory values.
