Abstract
Chronic idiopathic thrombocytopenic purpura is an autoimmune disorder in which the destruction of autologous platelets is mediated by autoantibodies directed against platelet-surface constituents.1 Glycoproteins IIb and IIIa, which exist in the platelet membrane in a 1:1 complex (IIb-IIIa), appear to be the main target molecules for these autoantibodies.2 3 4 The destruction of autologous platelets is thought to result from the ingestion of autoantibody-coated platelets by phagocytic cells in the spleen and other organs.1 The functional state of the reticuloendothelial system may influence the rate of cell destruction in individual patients.5
