title: Cyclosporine treatment of autoimmune chronic active hepatitis.
abstract: A 14-yr-old boy with a 5-yr history of autoimmune chronic active hepatitis refractory to corticosteroid therapy was given cyclosporin A (5 mg/kg X day). Before cyclosporine therapy, serum aminotransferase levels were 20 times normal and immunoglobulin G was 4 g/dl. Within 2 wk of starting cyclosporine therapy, aminotransferase levels decreased; by 2 mo they were almost normal, and at 1 yr into therapy they were normal. A decrease in cyclosporine dosage was associated with an increase in aminotransferase levels, which then again decreased as the dose was increased. Severe growth failure observed during previous corticosteroid therapy reversed during cyclosporine treatment and the patient displayed "catch-up" growth. No significant side effects were noted after 1 yr of cyclosporine therapy. Further evaluation of cyclosporine in the treatment of corticosteroid-unresponsive autoimmune chronic active hepatitis appears warranted.
