Heparin-Induced Thrombocytopenia: Molecular Pathogenesis
Heparin-induced thrombocytopenia (HIT), a relatively common complication of heparin therapy, is characterized by an unexpected fall in platelet count occurring 5 days or more after the initiation of treatment.1,2 Patients who manifest only the thrombocytopenia rarely experience severe bleeding or other major adverse effects.3 Often, however, the thrombocytopenia is accompanied by arterial and/o...
متن کاملHeparin induced thrombocytopenia
Abstract Background and Objectives Heparin is still a commonly used anticoagulant in prophylaxis and treatment of thromboembolic events. Heparin-induced thrombocytopenia (HIT) is a life-threating adverse drug reaction of heparin. The diagnosis of HIT is made based on two important criteria, firstly clinical evaluation and secondly laboratory testing. In this comprehensive review, the authors w...
متن کاملHeparin-induced thrombocytopenia: diagnosis and management.
Heparin is the predominant anticoagulant used in cardiac and vascular surgery. Heparin-induced thrombocytopenia (HIT) is one of the most serious and life-threatening adverse drug reactions associated with heparin use. In addition to the development of thrombocytopenia, HIT is associated with a high risk (40-50%) of thrombotic complications. The pathophysiology of HIT is now well understood and ...
متن کاملHeparin-Induced Thrombocytopenia Diagnosis and Management
Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction characterized by thrombocytopenia and a high risk for venous or arterial thrombosis.1 It is caused by heparin-dependent, plateletactivating antibodies that recognize a “self” protein, platelet factor 4 (PF4), bound to heparin. The resulting platelet activation is associated with increased thrombin generation (Figure).2 Typically...
متن کاملDiagnosis and management of heparin-induced thrombocytopenia.
PURPOSE To review recent developments in the pathogenesis, clinical features, laboratory testing and treatment of heparin-induced thrombocytopenia (HIT). METHODS Narrative review of the literature, including relevant papers published in English or French. PRINCIPAL FINDINGS Although the prevalence of HIT has decreased with the widespread use of low molecular weight heparin in the past ten y...
