BACKGROUND: This study was to investigate the association between thrombophilia and REM by the change of thrombophilia markers and to evaluate their contribution in diagnosis and treatment of REM. METHODS: 199 women with REM history were divided into two groups within the study group: 151 pregnant (REM-P) and 48 nonpregnant (REM-NP). In addition, 121 healthy age-matched women without REM history were divided into two groups of the control group: 75 pregnant (Control-P) and 46 nonpregnant (Control-NP). Lupus anticoagulant (LA), anticardiolipin antibodies (ACA), and anti-β2-glycoprotein-I antibodies (anti-β2GPI-ab) and coagulation-related factors such as protein S (PS), protein C (PC), anti-thrombin III (AT-III), and D-dimer were analysed. The prevalence of antiphospholipid antibodies (aPL) and the coagulation-related factors between groups were compared. RESULTS: The overall prevalence of aPL positivity in REM-P (14.57%) showed a difference compared with REM-NP (2.66%) but not for aCL, anti-β2GPI-ab or LA alone. There were significant differences in the mean levels of protein S, protein C, and AT-III in REM-P. The mean values of protein C (90.3 ± 28.42%) and protein S (71.80 ± 24.68%) in the aPL positive study group were similar with that of the aPL negative study group (p = 0.406, p = 0.880). Comparing with the aPL negative study group, the mean value of AT-III (87.71 ± 21.84%) was significantly lower (p = 0.018), while the mean value of D-dimer (0.98 ± 1.1 mg/L FEU) was significantly higher (p = 0.013). CONCLUSIONS: We briefly address the role of the prevalence of aPL and the related coagulation factors for predicting a prethrombotic state in patients with REM. The results of the use of anticoagulants for treating REM are encouraging.
