Abstract
ABSTRACT Hypertensive disorders in pregnancy (HDIP) represent one of the leading causes of maternal and perinatal mortality. microRNA (miR)-25-3p plays roles in HDIP diagnosis. We explored miR-25-3p clinical roles in HDIP. HDIP patients [gestation hypertension (GH), mild preeclampsia (mPE), and severe preeclampsia (sPEz)], and normal pregnant women serving as the control were enrolled. Serum miR-25-3p expression patterns were detected by RT-qPCR. The diagnostic efficacy of miR-25-3p on HDIP was analyzed with a ROC curve. Patients were assigned to the high/low miR-25-3p expression groups according to the median value of miR-25-3p expression. All patients were followed up until delivery, and gestational weeks and pregnancy outcomes were recorded at delivery. The effects of miR-25-3p expression on pregnancy outcomes of GH, mPE, and sPEz patients were analyzed by Kaplan-Meier. miR-25-3p expression in GH, mPE, and sPEz patients was up-regulated. In sPEz patients, systolic and diastolic blood pressure, 24-h urine protein, AST, ALT, GGT, and SCr were increased, and PLT was decreased in the high expression group. High miR-25-3p expression was associated with an increased risk of adverse pregnancy outcomes in PE patients. Collectively, high miR-25-3p expression could aid HDIP diagnosis, and associated with an increased risk of adverse pregnancy outcomes in PE patients.
