BACKGROUND AND PURPOSE We previously reported that patients with antiphospholipid antibodies (aPLs) frequently demonstrate cerebral infarction due to cerebral vasospasm after subarachnoid hemorrhage (SAH). To examine the participation of aPLs in the pathogenesis of vasospasm after SAH, we studied the relationships of aPLs and SAH in an animal model. METHODS SAH was produced in 34 rabbits that...

Antiphospholipid syndrome spans many medical disciplines. Classic criteria include the presence of anticardiolipin antibody or lupus anticoagulant with typical complications of thrombosis or pregnancy loss. Other common associated manifestations include livedo reticularis, thrombocytopenia, valvular heart disease, and nephropathy with renal insufficiency, hypertension, and proteinuria. Treatmen...

BACKGROUND Optic neuritis (ON) is often associated with other clinical or serological markers of connective tissue diseases (CTDs). To date, the effects of autoantibodies on ON are not clear. PURPOSE To assess the prevalence, clinical patterns, and short outcomes of autoantibodies and Sjögren's syndrome (SS) involvement in Chinese ON patients and evaluate the relationship between ON, includin...

A 44-year-old female developed a catastrophic thrombotic syndrome following allogeneic stem cell transplantation for acute lymphoblastic leukemia. In the context of chronic graft versus host disease, she developed a lethal multi-system thrombotic state as evidenced by stroke, renal failure and cardiac thrombi in association with elevated anticardiolipin antibody. The case is discussed in the fr...

Three cases of deep cerebral vein thrombosis presenting as encephalitic illnesses are described. Thyrotoxicosis was present in one case, ulcerative colitis in one case and an anticardiolipin antibody was detected in two cases. All three patients were on oestrogen and progesterone. Magnetic resonance imaging and angiography allowed rapid confirmation of the diagnosis and permitted non-invasive f...

Antiphospholipid syndrome is probably the most common acquired hypercoagulable state, but information on perioperative management is sparse. Minor alterations in anticoagulant therapy, infection, or a surgical insult may trigger widespread thrombosis. The perioperative course of a 31-yr-old woman with primary anticardiolipin antiphospholipid antibody syndrome requiring a mitral valve replacemen...

A child with systemic onset juvenile chronic arthritis (JCA) who developed a bilateral femuropopliteal vein thrombosis after plaster immobilisation following a tibial fracture is described. When the thrombosis was diagnosed, antiphospholipid antibodies detected either as lupus anticoagulant and anticardiolipin antibodies were found. This suggests that short term prophylatic antithrombotic treat...
