Antithrombotic and Antiplatelet Therapy

Book section · January 1, 2023 Parenteral anticoagulant therapies include heparin and related compounds, as well as the direct thrombin inhibitors argatroban and bivalirudin. Commonly used fibrinolytic therapies include alteplase, reteplase, and tenecteplase. Oral anticoagulant therapie ... Full text Cite

Antiphospholipid Syndrome

Book section · January 1, 2022 Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by venous and/or arterial thromboembolic events, pregnancy morbidity, and the presence of antiphospholipid antibodies. These autoantibodies bind to β2-glycoprotein I and other phosphol ... Full text Cite

Hematology: Cytopenias

Book section · January 1, 2021 Cytopenias are frequently encountered in patients with systemic lupus erythematosus (SLE), and leukopenia (white blood cell count <4000/mm3), thrombocytopenia (platelet count <100, 000/mm3), and autoimmune hemolytic anemia (defined by ... Full text Cite

Antithrombotic Therapy

Book section · January 1, 2021 Antithrombotic therapy, which includes therapies targeting platelets as well as the coagulation system, is used to prevent and treat thromboembolic disease. Antiplatelet agents are most frequently used to prevent stroke and myocardial infarction, but they ... Full text Cite

Antiphospholipid Syndrome

Book section · January 1, 2019 Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by venous and/or arterial thromboembolic events, recurrent pregnancy morbidity, and the persistent presence of antiphospholipid antibodies. These autoantibodies bind to β2-glycoprotein ... Full text Cite

Recent Advances in Understanding of the Genetics of Antiphospholipid Syndrome

Book section · January 1, 2017 Available evidence supports an inherited risk for the occurrence of antiphospholipid antibodies (aPL), with or without the clinical manifestations associated with antiphospholipid syndrome (APS). Immediate relatives of individuals with APS, whether primary ... Full text Cite

15th International Congress on Antiphospholipid Antibodies Task Force on Antiphospholipid Syndrome Treatment Trends Report

Book section · January 1, 2017 A challenge in antiphospholipid syndrome (APS) is to translate targeted therapies from animal and in vitro models to clinical trials. The 15th International Congress on Antiphospholipid Antibodies (aPL) Task Force on Treatment Trends summarized new develop ... Full text Cite

15th International Congress on Antiphospholipid Antibodies Task Force on Catastrophic Antiphospholipid Syndrome Report

Book section · January 1, 2017 Catastrophic antiphospholipid syndrome (CAPS) is a systemic disorder, resulting in both thrombotic and non-thrombotic events. Thrombosis manifests mainly as thrombotic microangiopathy (TMA), although large-vessel thrombosis occurs in up to one third of pat ... Full text Cite

Nephrology

Book section · January 1, 2016 Patients with renal diseases have their own particular complications of hemostasis and thrombosis. Bleeding and platelet dysfunction is a common complication of chronic kidney disease and uremia. Similarly, coagulation activation and risk of thrombosis is ... Full text Cite

Anticoagulation for venous thromboembolism

Book section · January 1, 2014 Anticoagulation is a fundamental of management in venous disease. This chapter discusses anticoagulant therapy and a variety of agents. The current treatment for a new venous thromboembolic event in a patient is anticoagulant therapy, beginning with either ... Full text Cite

Molecular testing for coagulation abnormalities

Book section · March 1, 2013 Molecular testing is frequently used in conjunction with other laboratory analyses in the evaluation of patients with hemorrhagic as well as thrombotic disorders. The most common thrombophilic defects, factor V Leiden and the prothrombin G20210A mutation, ... Full text Cite

What is the genetics of antiphospholipid antibodies/syndrome?

Book section · January 1, 2012 An inherited risk for the occurrence of antiphospholipid antibodies (aPLs), with or without the clinical manifestations associated with antiphospholipid syndrome (APS), is supported by multiple lines of evidence. Family members of patients with APS, whethe ... Full text Cite
