Assessment of maternal serum SERPINC1, E-selectin, P-selectin, and RBP4 levels in pregnancies with early- and late-onset preeclampsia.

Abstract

To investigate whether the SERPINC1, E-selectin, P-selectin, and RBP4 levels in first trimester maternal serum was associated with the presence of preeclampsia (PE). This cross-sectional study was conducted on 26 women with early-onset preeclampsia (EO-PE), 27 women with late-onset preeclampsia (LO-PE), and 27 women with uncomplicated pregnancies. Levels of serum SERPINC1, E-selectin, P-selectin, and RBP4 were measured with the use of an enzyme-linked immunosorbent assay (ELISA) kit. E-Selectin levels in patients with EO-PE were higher than those with LO-PE and control patients (pE-L =0.025; pE-C =0.000; p < 0.05). There was no significant intergroup difference in terms of P-selectin and RBP4 levels (p > 0.05). SERPINC1 levels were lower in the patients in the with EO-PE group than in those in the LO-PE and the control groups (pE-L =0.000; pE-C =0.000; p < 0.05). In the PE group, there was a negative, moderate (41.7%) correlation between E-selectin level and SERPINC1 (p=0.002; p < 0.05). The receiver operating characteristic (ROC) curve showed that the best cut-off values for E-selectin were 23.14 ng/ml > with 100% sensitivity and 100% specificity. The ROC curve showed that the best cut-off values for SERPINC1 were ≤87.76 ng/ml with 98.1% sensitivity and 96.3% specificity. Of the endothelial damage parameters, E-selectin and SERPINC1 are especially associated with EO-PE. Furthermore, they can be used as potential early diagnosis markers in the prediction of PE.
