Clinical Features and Pattern of Antiphospholipid Antibodies in Patients of Antiphospholipid Syndrome (APS) With Systemic Lupus Erythematosus (SLE).

Antiphospholipid syndrome (APS) is characterized by presence of specific antiphospholipid antibodies (aPL) with history of thrombosis and/or pregnancy morbidity.

Anti-phospholipid antibodies (aPL) is a comprehensive antibody profile which includes lupus anticoagulant [LA], anticardiolipin antibodies [aCL], and/or anti-β2-glycoprotein-I antibodies [aβ2GPI]). A comprehensive antibody profile is needed for both diagnosis and classification of patients with APS, most significantly for the risk assessment of both pregnancy morbidity and thrombosis.

Double positivity (LA, aβ2GPI or ACL +) and triple positivity (LA, aβ2GPI+, ACL +) may have worse outcome and the patients with double and triple positivity may have recurrent thrombotic events.

Early detection of aPL antibodies may avert patients with many complication associated with SLE as well as from major thrombotic events because the detection of aPL in SLE has been proposed as a predictive and specific tool for the diagnosis of APLS in SLE.

aPL profile in SLE patients with obstetric and thrombotic complications was analyzed, to see the association of different anti phospholipid antibodies with different clinical features of APLS in SLE patients.
