The prevalence of lupus anticoagulant, using the dilute Russell's viper venom time (DRVT), was determined in 22 patients with mild to severe haemophilia A to see if there was any association with the presence of viral disease. Twelve haemophiliacs (58%) were lupus anticoagulant positive, with a mean patient:control ratio of 1.24 (range 1.15-1.52, normal range 0.84-1.06 which partially corrected...
We present functional and binding data relevant to the reported roles for prothrombin and beta 2-glycoprotein I (beta 2GPI) in the expression of lupus anticoagulant activity. In a purified system containing human prothrombin, Xa, Va, and a rate-limiting concentration of phosphatidylserine (PS)/phosphatidylcholine (PC) vesicles, the preliminary incubation of vesicles with protein A separated IgG...
Two young adults with lupus anticoagulant had multiple attacks of cerebrovascular ischemia in different arterial territories. Cerebral angiography was normal. One patient had a new episode during anticoagulant therapy, but has remained asymptomatic on antiplatelet treatment. In the other, further events occurred during treatment with platelet-inhibiting drugs, but there have been no recurrences...
Although observations have implied that lupus anticoagulants have immunologic specificity toward anionic phospholipids. this assumption has been directly demonstrated in only one patient with a monoclonal 1gM paraprotein. We tested the generality of this hypothesis directly by isolating five lgG lupus anticoagulants from patients with lupuslike syndromes and/or thrombosis. lgG lupus anticoagula...
We report two cases of cerebral venous sinus thrombosis associated with an antibody to phospholipids, namely the lupus anticoagulant. Both patients later developed further immunologically mediated conditions. The importance of screening for the lupus anticoagulant in addition to anticardiolipin antibodies in this condition and the need for follow-up of such patients is discussed.
OBJECTIVE Lupus anticoagulant and anticardiolipin antibodies (aCL) have been associated with thrombosis, recurrent abortion, and thrombocytopenia in patients with systemic lupus erythematosus (SLE), but their relationship with cardiac disease is less clear. The purpose of this study was to evaluate the association between antiphospholipid antibodies (aPL) and echocardiographic abnormalities in ...
BACKGROUND A high incidence of both arterial and venous thromboembolic events has been reported in patients with systemic lupus erythematosus (SLE), but the risks and benefits of primary prophylactic antithrombotic therapy have not been assessed. We measured the clinical benefit of 3 antithrombotic regimens in patients with SLE without antiphospholipid antibodies, with anticardiolipin antibodie...
BACKGROUND AND PURPOSE Antiphospholipid antibodies have been associated with ischemic stroke in some but not all studies. METHODS We performed a population-based case-control study examining antiphospholipid antibodies (anticardiolipin antibodies and lupus anticoagulants) using stored frozen sera and plasma in 160 cases and 340 controls enrolled in the Stroke Prevention in Young Women study. ...
