Antiphospholipid antibody syndrome (APS) is a systemic autoimmune disease with thrombotic predilection resulting in vascular thrombotic events and obstetric complications. Management of APS focuses on anticoagulation; however, despite the solid evidence suggesting that this is the best treatment option available, a lot of debate persists regarding the intensity and duration of anticoagulation n...

The laboratory criteria that define patients with antiphospholipid syndrome (APS) include lupus anticoagulant (LAC), anticardiolipin antibodies and anti-β2 glycoprotein I antibodies (aβ2GPI). All assays show methodological shortcomings and the combination of the three tests, each with different sensitivity and specificity, and hence, differences in clinical utility make the laboratory diagnosis...

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. ...

OBJECTIVE To describe a case of propylthiouracil-induced lupus, complicated with antiphospholipid syndrome and acute ischemic stroke. DESIGN Case report. SETTING Academic medical center. PATIENT A 27-year-old man with a diagnosis of Graves disease developed multiple ischemic strokes 2 weeks after starting treatment with propylthiouracil. Thyrotoxicosis and abnormal hypercoagulable and rhe...

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...

Introduction The antiphospholipid antibody syndrome (APS) is a multisystemic autoimmune disease characterized by thromboembolic events, pregnancy morbidity, hematologic, dermatologic, neurologic and other manifestations in the presence of elevated titers of antiphospholipid antibodies (aPL). In recent years, APS has been increasingly recognized in various pediatric autoimmune and nonautoimmune ...

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...

The mechanism underlying the prothrombotic state that characterizes the primary antiphospholipid syndrome proves to be difficult to define mainly because of the variety of the phospholipid and protein targets of antiphospholipid antibodies that have been described. Much of the debate is related to the use of polyclonal antibodies during the different antiphospholipid assays. To better describe ...

In a 2-year prospective study of 146 patients with cerebral ischemia, we compared vascular risk factors for stroke with clinical and laboratory findings, particularly antiphospholipid antibodies. Ten patients (6.8%) were positive for at least one antiphospholipid antibody; one patient had systemic lupus erythematosus, one had rheumatoid arthritis, and the remaining eight fulfilled criteria for ...

In recent years, the association between infections and antiphospholipid syndrome has been reported in several epidemiologic and experimental studies that support the idea of infectious induction of aPL [2]. Witmer, et al. [3] reported two children with Mycoplasma pneumoniae pulmonary infection complicated by the development of splenic infarction and transient antiphospholipid antibodies. Among...
