This article provides a review of the various types of antiphospholipid (aPL) antibodies and antiphospholipid syndromes, their prevalence, presumed origin, relationship to autoimmunity in general, and their role in the body's defenses and apoptosis. New hypotheses such as the role of antibodies to beta2 glycoprotein I (beta2GPI) and the signaling of toll-like receptors are also discussed, as is the spectrum of clinical manifestations associated with the demonstration of these antibodies, now assumed to be "pathogenic...

Antiphospholipid syndrome (APS) is a thrombotic disorder associated with autoantibodies that target membrane phospholipids and phospholipid-binding proteins, which regulate coagulation. APS is usually characterized by major arterial or venous occlusions, pregnancy complications, or both. In 1992, Asherson described an unusual variant of APS termed the catastrophic antiphospholipid syndrome (also known as Asherson's syndrome), the hallmark of which is rapid multiorgan failure caused by widespread small-vessel thrombi...
