title: [Monoclonal antibody therapy for disorders of hemostasis and coagulation].
abstract: Monoclonal antibody therapies have conducted to not only hematologic malignancies but also disorders of hemostasis and coagulation. This article describes the recent advances of monoclonal antibody therapy for bleeding disorders such as idiopathic thrombocytopenic purpura(ITP), hemophilia A, disseminated intravascular coagulation(DIC), and thrombosis. Rituximab, chimeric anti-CD20 monoclonal antibody treatment has a valuable effect in the patients with ITP, and clinical trials using anti-CD40 ligand monoclonal antibody for ITP are underway. Anti-CD40 ligand monoclonal antibody can be an alternative therapy for hemophilia A patients with inhibitors to factor VIII. In thrombosis, anti-tissue factor monoclonal antibody and anti-factor IX(a) monoclonal antibody were established as novel anticoagulant regents. Plasminogen activator inhibitor-1(PAI-1) increases in endotoxin-induced DIC and many thrombotic diseases such as myocardial infarction, type 2 diabetes mellitus, and hyperlipidemia. Anti-PAI-1 monoclonal antibody reduced fibrin deposition in DIC mouse model. Treatment of these monoclonal antibodies for the molecules regulating coagulation-fibrinolysis system may be utilized for acute coronary syndrome and venous thrombosis.
