RESUMO
Idiopathic thrombocytopenic purpura (ITP) is defined as isolated thrombocytopenia without a clinically apparent cause. It is categorized as acute, chronic, and refractory. Its clinical presentation ranges from acute to insidious and the bleeding may vary from minimal to severe. The target platelet count with therapy is more than 30,000/microL in sedentary individuals. Since studies regarding therapies for ITP have been mostly uncontrolled case series, the treatment recommendations are largely derived from expert opinion. This review paper summarizes the data on available therapies for adult acute and chronic/refractory ITP. The therapies include splenectomy, steroids, intravenous immunoglobulin, anti-Rh(D), monoclonal antibodies, danazol, chemotherapy, plasma exchange, and others.
