Lupus anticoagulants are a heterogeneous group of autoantibodies directed against hemostatically active phospholipids and phospholipid-protein complexes. The presence of lupus anticoagulants can predispose to thrombosis and recurrent abortion. Both arterial and venous thrombosis have been described. Reduced anticoagulant activity of activated protein C has been discussed as a possible pathophysiologic mechanism. Various functional and immunologic tests are available for detecting lupus anticoagulants. The definitive diagnosis of a lupus anticoagulant requires a positive result in two independent functional tests or the simultaneous detection of a lupus anticoagulant in one functional and one immunologic test. Treatment aims at the prevention of thromboembolic complications, so patients should remain on oral anticoagulation until lupus anticoagulant parameters have normalized.
