Treatment of antiphospholipid syndrome

The antiphospholipid syndrome (APS) is a disorder of recurrent thrombosis and/or pregnancy loss associated with the presence of antiphospholipid antibodies and persistently positive lupus anticoagulant, anticardiolipin or anti beta2-glycoprotein1. Oral anticoagulants are the best available and most effective treatment for the secondary prevention of recurrent venous or arterial thrombosis. Patients with APS are treated with long-term therapy to prolong the INR to 2.0-3.0. Low-molecular-weight heparin in combination with low-aspirin dose is a reasonable strategy to avoid pregnancy loss in women with this syndrome.
