title: Treatment options for chronic idiopathic (immune) thrombocytopenic purpura.
abstract: The goal of treatment for idiopathic (immune) thrombocytopenic purpura (ITP) is to prevent serious bleeding. Traditionally, corticosteroids have been used as first-line therapy followed by splenectomy. Experience with splenectomy over 60 years shows that approximately two thirds of patients achieve normal platelet counts during the initial observation, but that thrombocytopenia often recurs with longer follow-up. We know that long-term use of corticosteroids can lead to significant morbidities; there is no consensus regarding the appropriate timing or indications for splenectomy. To address the Issue of appropriate use of splenectomy, we designed a multicenter clinical trial that will randomize patients to either standard care, involving prednisone followed by splenectomy, or to a novel regimen of limited prednisone treatment followed by WinRho SDF (Nabi, Boca Raton, FL) (anti-D) therapy to maintain the platelet count in a safe range for 1 year. Anti-D can be administered easily in an outpatient setting with few side effects and can provide predictable, transient increases in platelet count. The hypothesis is that prolonged maintenance therapy with a nontoxic regimen may increase the percentage of patients who will experience a spontaneous remission from thrombocytopenia, thereby avoiding an invasive and permanent surgical procedure, splenectomy, and its potentially life-threatening sequelae.
