Are serum levels of inhibin A in second trimester predictors of adverse pregnancy outcome?

ABSTRACT: OBJECTIVE:During pregnancy, inhibin A is mainly derived from the placenta and regulates the implantation and differentiation of embryos. Our aim was to assess whether second trimester serum inhibin A was associated with an increased risk of adverse pregnancy outcomes. METHODS:We investigated the serum levels of Inhibin A during the second trimester in pregnancy, and analyzed associations between the Inhibin A and the risk of adverse pregnancy outcome. 12,124 pregnant women were enrolled in this study between January 2017 and July 2019 at the Obstetrics & Gynecology Hospital of Fudan University. Multivariate logistic regression analysis was conducted to estimate the relative risk between Inhibin A and adverse pregnancy outcome. RESULTS:Compared with the group without adverse pregnancy outcome, during the second trimester of pregnancy, age and Inhibin A were risk factors for pre-eclampsia, gestational diabetes mellitus and preterm delivery; Inhibin A was risk factors for low birth weight. Gravidity and Inhibin A were risk factors for macrosomia; while parity was a protective factor against pre-eclampsia, gestational hypertension and low birth weight. CONCLUSION:Elevated Inhibin A levels in pregnancy are significantly associated with pre-eclampsia, GDM, macrosomia, low birth weight and preterm delivery.

Project description:ObjectiveTo estimate the risk of adverse perinatal outcomes among women with isolated fetal growth restriction from 17 to 22 weeks of gestation.MethodsThis was a retrospective cohort study of all singleton, nonanomalous pregnancies undergoing ultrasonography to assess fetal anatomy between 17 and 22 weeks of gestation at a single center from 2010 to 2014. After excluding patients with fetal structural malformations, chromosomal abnormalities, or identified infectious etiologies, we compared perinatal outcomes between pregnancies with and without fetal growth restriction, defined as estimated fetal weight less than the 10th percentile for gestational age. Our primary outcome was small for gestational age (SGA) at birth, defined as birth weight less than the 10th percentile. Secondary outcomes included preterm delivery at less than 37 and less than 28 weeks of gestation, preeclampsia, abruption, stillbirth, neonatal death, neonatal intensive care unit admission, intraventricular hemorrhage, need for respiratory support, and necrotizing enterocolitis.ResultsOf 12,783 eligible patients, 355 (2.8%) had early second-trimester fetal growth restriction. Risk factors for growth restriction were African American race and tobacco use. Early second-trimester growth restriction was associated with a more than fivefold increase in risk of SGA at birth (36.9% compared with 9.1%, adjusted odds ratio [OR] 5.5, 95% CI 4.3-7.0), stillbirth (2.5% compared with 0.4%, OR 6.2, 95% CI 2.7-12.8), and neonatal death (1.4% compared with 0.3%, OR 5.2, 95% CI 1.6-13.5). Rates of indicated preterm birth at less than 37 weeks of gestation (7.3% compared with 3.3%, OR 2.3, 95% CI 1.5-3.5) and less than 28 weeks of gestation (2.5% compared with 0.2%, OR 10.8, 95% CI 4.5-23.4), neonatal need for respiratory support (16.9% compared with 7.8%, adjusted OR 1.6, 95% CI 1.1-2.2), and necrotizing enterocolitis (1.4% compared with 0.2%, OR 7.7, 95% CI 2.3-20.9) were also significantly higher for those with growth restriction. Rates of preeclampsia, abruption, and other neonatal outcomes were not significantly different.ConclusionAlthough fetal growth restriction in the early second trimester occurred in less than 3% of our cohort and most of those with isolated growth restriction did not have adverse outcomes, it is a strong risk factor for SGA, stillbirth, neonatal death, and indicated preterm birth.
