Estimated value of uterine blood flow parameters combined with serum CA125 and STAT4 levels in the second trimester of pregnancy on pregnancy outcome in patients with preeclampsia
ObjectiveTo investigate the estimated value of uterine blood flow parameters combine with serum carbohydrate antigen 125 (CA125) level and serum signal transducer and activator of transcription 4 (STAT4) level in the second trimester of pregnancy on pregnancy outcome in patients with preeclampsia. MethodsA total of 127 patients with preeclampsia were selected as the research subjects, and they were divided into adverse outcome group (32 cases) or favorable outcome group (95 cases) according to pregnancy outcome. The clinical data, uterine blood flow parameters in terms of uterine arterial resistance index (RI), uterine arterial pulsation index (PI), and serum CA125 and STAT4 levels from 20 to 25 weeks of pregnancy were compared between patients of the two groups. The multivariate Logistic regression model was used to analyze the influencing factors for pregnancy outcome in patients with preeclampsia. The value of uterine arterial RI and PI, and serum CA125 and STAT4 levels for single and combined prediction on pregnancy outcome in patients with preeclampsia was analyzed by using the receiver operating characteristic curve. ResultsThe incidence rate of adverse pregnancy outcome in preeclampsia patients was 25.19% (32/127). The adverse outcome group exhibited higher uterine arterial RI and PI, higher serum CA125 and STAT4 levels, and a higher proportion of patients with severe preeclampsia, as well as a higher alpha fetoprotein level as compared with the favorable outcome group (P<0.05). The elevations of uterine arterial RI and PI, serum CA125 level, and serum STAT4 level were the risk factors for adverse pregnancy outcome in patients with preeclampsia (P<0.05). The areas under the curve of uterine arterial RI and PI, serum CA125 level, serum STAT4 level for single and combined prediction on pregnancy outcome in patients with preeclampsia were 0.836, 0.812, 0.813, 0.785, and 0.978, respectively, and the area under the curve of the four combined prediction was higher than that of the four for single prediction (P<0.05). ConclusionThe elevations of uterine arterial RI and PI, serum CA125 level, and serum STAT4 level in the second trimester of pregnancy are all risk factors for adverse pregnancy outcome in patients with preeclampsia, and the combined evaluation of the four indices exerts a relatively high predictive efficiency for pregnancy outcome in patients with preeclampsia.
