Antiphospholipid syndrome

APS can be primary or secondary. Primary antiphospholipid syndrome occurs in the absence of any other related disease. Secondary antiphospholipid syndrome is often associated with systemic lupus erythematosus and less frequently with infections, drugs and other diseases. Serologic markers are antiphospholipid antibodies, lupus anticoagulant and anticardiolipin. In rare cases, APS leads to rapid...

Antiphospholipid syndrome

The antiphospholipid syndrome (APS) is defined by the development of venous and/or arterial thromboses, often multiple, and pregnancy morbidity (mainly, recurrent fetal losses), in the presence of antiphospholipid antibodies (aPL). Some estimates indicate that the incidence of the APS is around 5 new cases per 100,000 persons per year and the prevalence around 40-50 cases per 100,000 persons. T...

Revisiting Beta 2 Glycoprotein I, the Major Autoantigen in the Antiphospholipid Syndrome

Beta 2 glycoprotein I (β2GPI) is a single chain 50 kDa highly glycosylated glycoprotein at an approximate concentration of 4 μM in cells. The abundance of this protein in plasma and its high state of preservation indicate the important role of this protein in mammalian. In addition, β2GPI has a particular structure in the fifth domain, and is categorized as the major antigen recognized by autoa...
