title: The presence of anti-phosphatidylserine/prothrombin antibodies as risk factor for both arterial and venous thrombosis in patients with systemic lupus erythematosus.
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.
