[The infusion of high-dose immunoglobulins in a case of idiopathic thrombocytopenic purpura]

Idiopathic thrombocytopenic purpura (ITP) is a disease characterized by the presence of circulating antiplatelet antibodies, which can cause platelet destruction, through the mediation of the reticuloendothelial system (RES). We report on a patient affected with ITP insensible to first line steroid therapy, who achieved a complete response following the administration of high-dose immunoglobulins (HDIgG, 400 mg/kg/die for 5 days), in association with decreasing doses of steroids. At the end of the treatment with immunoglobulins, the patient presented a normal platelet count and, up to date, 5 moths from the end of therapy, he is in good shape and presents normal platelets values.
