Abstract
Two patients with immune thrombocytopenic purpura (ITP) refractory to conventional management with steroids and splenectomy were treated with 5‐day courses of intravenous gamma globulin (Gamimune‐Cutter), 400 mg/kg/day. Improvement was observed in both cases even while steroids were being tapered. In each case when thrombocytopenia subsequently recurred or worsened, further therapy with IV gamma globulin without concomitant steroids was followed by definite increase in platelet numbers. These observations confirm that the Cutter preparation of IV gamma globulin is efficacious in the management of refractory ITP and suggest that in this clinical setting response to IV gamma globulins can occur without concomitant administration of corticosteroids.
