Abstract

In an effort to clarify the clinical significance of anti-phospholipid antibodies (aPL) detected by enzyme-linked immunosorbent assay (ELISA), we examined the prevalence of anti-cardiolipin antibodies (aCL), anti-beta2-glycoprotein I antibodies (anti-beta2-GPI), antiprothrombin antibodies (anti-PT), and anti-phosphatidylserine/prothrombin antibodies (anti-PS/PT) in 175 patients with systemic lupus erythematosus (SLE) comprising 67 patients with thrombotic complications. The present study showed that positive results of anti-beta2-GPI-ELISA and anti-PS/PT-ELISA could serve as markers of thrombotic complications in patients with SLE, whereas aCL and anti-PT are less reliable as markers of these complications. Furthermore, results of the anti-PS/PT-ELISA correlate best with the occurrence of both arterial and venous thrombosis in patients with SLE.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.
