    Immune thrombocytopenia (ITP) is an acquired hemorrhagic condition of accelerated platelet consumption caused by antiplatelet autoantibodies, and glycoprotein (GP)IIb/IIIa is one of the major target antigens recognized by platelet-reactive CD4+ T cells. Patients with ITP often have few bleeding symptoms despite very low platelet counts, suggesting that ITP platelets are highly functional. Several factors may contribute to the prothrombotic state in ITP. We investigated the effect of thrombopoietin (TPO)-receptor agonist (RA) on the procoagulant state in ITP with or without anti-GPIIb/IIIa antibody. Long-term administration of eltrombopag resulted in stabilization of platelet numbers in many patients. On the other hand, when the analysis was carried out according to the presence of GPIIb/IIIa autoantibodies, the increase in platelet counts in ITP patients was more significant with than..
