چکیده

The lupus anticoagulant, an acquired circulating serum y-globulin, prolongs all phospholipid-dependent coagulation tests. Recent associations of the lupus anticoagulant and focal cerebral and/or ocular ischemia have been made. We present 5 cases of lupus anticoagulant-associated cerebrovascular ischemia and review all reported cases for the first time. Clinical spectra, cerebral angiographic findings, associated conditions, and response to therapy are presented. Typical features include a relatively young age (mean 39 years), female preponderance, transient ischemic attacks (including amaurosis fugax) or stroke, and normal or large vessel occlusions on angiography. Commonly associated conditions were systemic lupus erythematosus (34%), noncerebral venous thrombosis (31%), hypertension (28%), false-positive VDRL (28%), and spontaneous abortions (22%). Four of our 5 patients (all without systemic lupus erythematosus) and 11 of the 20 (55%) patients in the literature without systemic lupus erythematosus had other definite stroke risk factors coexisting. Response to therapy was highly variable, with no clear beneficial effect of corticosteroids. (Stroke 1987;18:257263)

Comments, Opinions, and Reviews Hemorrhagic Complications of Long-Term Anticoagulant Therapy for Ischemic Cerebral Vascular Disease

The main complication of anticoagulant therapy is bleeding. Although the use of long-term oral anticoagulants in patients with transient cerebral ischemia and/or minor stroke is controversial, anticoagulants are still used in some instances. We have carried out a literature review of the risk of hemorrhage during long-term oral anticoagulant therapy in patients with cerebrovascular disease to d...

Comments, Opinions, and Reviews Anticoagulant Therapy in Cerebrovascular Disease: Review and Meta-analysis

Sixteen acceptably randomized studies of anticoagulant therapy after cerebral or retinal ischemia or infarction are reviewed and the results among 1,046 anticoagulated patients and 1,071 controls are analyzed. The following conclusions are derived. 1) Anticoagulant therapy has not been shown to be better than control management after transient ischemia or nonprogressing ischemic stroke; this is...

Recurrent ischemic attacks in two young adults with lupus anticoagulant.

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...

Lupus anticoagulants, anticardiolipin antibodies, and cerebral ischemia.

We studied 23 patients suffering cerebral ischemia who also had laboratory evidence of either a lupus anticoagulant (LA) or an abnormal anticardiolipin antibody (ACA). Four patients had lupus or a lupus-like illness, three had drug-induced lupus, and 16 had no overt evidence of collagen-vascular disease. Cerebral ischemic events were multiple in 71% of the patients; two patients presented with ...
