Application Value of Combined Detection of Anti-β2-GPI, ACL, and Lupus Anticoagulant in the Diagnosis of Patients with Antiphospholipid Syndrome

Abstract

Objective. To investigate the application value of combined detection of anti-beta 2-glycoprotein I antibody (anti-β2-GPI), anti-cardiolipin antibody (ACL), and lupus anticoagulant (LA) in the diagnosis of patients with antiphospholipid syndrome (APS). Methods. 30 APS patients in our hospital between Jan. 2020 and Jan. 2021 were chosen as the experimental group, and 30 healthy persons with normal physical examination during the same period were selected as the control group The anti-β2-GPI and ACL indexes of both groups were detected by enzyme-linked immunosorbent assay (ELISA), with the LA levels tested by modified dilute Russell’s viper venom time (dRVVT) and LA ratio calculated. The diagnostic efficacy of single detection and combined detection was analyzed by plotting the receiver operating characteristic (ROC) curve. Results. The serum indexes in the experimental group were remarkably higher than those in the control group ( P < 0.001 ). ROC curve analysis suggested that in the diagnosis of APS, the area under the ROC curve by detecting anti-β2-GPI, ACL, LA ratio alone and simultaneously were 0.517, 0.583, 0.683, and 0.817 respectively, and the combined detection of the three had remarkably higher sensitivity and specificity than those of each single detection. Conclusion. The indexes of anti-β2-GPI, ACL, and LA ratio were highly expressed in APS patients, and the combined detection of the three has high diagnostic value and can effectively screen and assist the diagnosis of APS.
