Prediction of Preeclampsia by Comprehensive Markers.

Peking Union Medical College Hospital11,741 enrolled

Overview

Preeclampsia is one of the most serious complications in pregnancy that causes maternal death and preterm delivery. Series studies has show that the competing risk model developed by the Fetal Maternal FouNdation in early pregnancy has the potential to predict preeclampsia effectively but has show crowd difference. We aim to evaluate the performance of various screening model based on FMF model in Chinese population.

The prospective multi-center observational study aimed to recruit at least 10,000 pregnant woman during the first trimester conducted among 12 medical centers in China. The medical history of each candidate was recorded , blood pressure was measured , blood sample was taken between 11 gestational weeks and 13+6 gestational weeks, to get the PlGF and PAPPA tested. Routine ultrasound was taken with measurement of the uterine artery pulsatility index. The results of the recruited patients were not released to the patients or the doctor. Pregnancy outcome was recorded as to whether the women develop preeclampsia , the SGA babies, or low birth Apgar score and other preeclampsia related adverse maternal and neonatal outcomes. The basic medical information, the mean artery pressure, the PlGF and PAPPA MOM, the UtA PI were used in combination to do the risk stratification, and to develop prediction model for Chinese people.
