| Outline of Final Research Achievements |
We newly developed an ELISA system for simultaneous detection of six specific categories of aPLs: anti-cardiolipin (aCL), anti-β2-glycoprotein I (aβ2GPI), anti-cardiolipin/β2-glycoprotein I (aCL/β2GPI), anti-phosphatidylserine (aPS), anti-prothrombin (aPT), and anti-phosphatidylserine/prothrombin (aPS/PT).They were measured in 331 patients with SLE including 63 patients with arterial thromboembolic complications, 64 with venous thromboembolic complications, and 43 with recurrent fetal loss.The concentration of aPS/PT was most closely associated with arterial thrombosis. In contrast, the concentration of aβ2GPI was most closely related to venous thrombosis. Furthermore, both aCL/β2GPI and aPS/PT were independently associated with episodes of recurrent fetal loss.
Anti-phospholipid syndrome in patients with SLE can be classified by antigenic specificities of their aPLs as to their susceptibility to arterial and/or venous thromboembolic complications or obstetric complications.
