title: Diamond-blackfan anemia and cyclosporine therapy revisited.
abstract: A girl with Diamond-Blackfan anemia diagnosed in infancy started cyclosporine A (CSA) therapy at 9 years and 8 months of age after experiencing unacceptable side effects while receiving prednisone. Since then, she has been followed-up for more than 4 years. She exhibited a dramatic response to CSA, with weaning and then cessation of steroid therapy after 5 months. She has remained transfusion-independent. Attempts to discontinue CSA therapy have been unsuccessful. Relapse of the anemia has occurred in the context of viral infections with missed CSA doses. The major clinical problem during treatment has been recurrent oral aphthous ulceration, which responds to topical therapy. She is currently maintained on CSA 100 mg twice daily with a hemoglobin of 10.2 g/dL and a reticulocyte count of 1.6%. A trial of CSA therapy should be considered in patients with Diamond-Blackfan anemia in whom steroid therapy has failed before a transfusion program is instituted or alternative donor stem cell transplantation is entertained.
