Durable remission of pure red cell aplasia after treatment with high-dose intravenous gammaglobulin and prednisone.

Pure red cell aplasia (PRCA) is a rare disorder of erythrocyte production believed to have an autoimmune basis in most cases. Responses to a variety of immunosuppressive regimens are regularly observed, but toxicity is considerable. Brief responses to high-dose intravenous immunoglobulin (IVIg) have been previously reported. This case demonstrates a durable clinical remission of PRCA treated with IVIg and glucocorticoids.
