To determine the inter-relationships between five first-trimester biomarkers (pregnancy associated plasma protein A [PAPP-A], alpha-fetoprotein [AFP], beta human chorionic gonadotrophin [beta-hCG], placenta growth factor [PlGF] and soluble fms-like tyrosine kinase receptor-1 [sFlt-1]) and a range of adverse pregnancy outcomes (APOs).
Prospective cohort study of nulliparous singleton pregnancy.
Cambridge, UK.
4056 pregnancy outcome prediction study participants.
The biomarker concentrations were measured in maternal serum at ~12 weeks of gestation. Univariable analysis of APOs was performed using logistic regression. Multivariable analysis used best subsets logistic regression with cross-validation.
Pre-eclampsia (PE), small for gestational age (SGA), including severe SGA (birthweight <3rd), fetal growth restriction (FGR), preterm birth (PTB, both induced and spontaneous [iPTB and sPTB, respectively]), pre-viable loss and stillbirth, plus combinations of outcomes.
Lower values of PAPP-A, PlGF and sFlt-1 and higher values of AFP were associated with FGR (OR for 1 SD higher value 0.59 [95% CI 0.48-0.74], OR 0.56 [95% CI 0.44-0.70], OR 0.68 [95% CI 0.54-0.87] and OR 1.53 [95% CI 1.25-1.88]), severe SGA (OR 0.59 [95% CI 0.49-0.72], OR 0.71 [95% CI 0.57-0.87], OR 0.74 [95% CI 0.60-0.91] and OR 1.41 [95% CI 1.17-1.71]), sPTB (OR 0.61 [95% CI 0.50-0.73], OR 0.79 [95% CI 0.66-0.96], OR 0.57 [95% CI 0.47-0.70] and OR 1.41 [95% CI 1.18-1.67]) and iPTB (OR 0.72 [95% CI 0.57-0.91], OR 0.62 [95% CI 0.49-0.78], OR 0.71 [95% CI 0.56-0.90] and OR 1.44 [95% CI 1.16-1.78]), respectively. When combinations of biomarkers were assessed, PAPP-A and AFP were independently associated with severe SGA; PAPP-A alone with PE + PTB; PlGF alone with severe PE; PlGF, beta-hCG, AFP and PAPP-A with the combination of PE and SGA; AFP and sFlt-1 with sPTB; and AFP and PlGF with iPTB.
Combinations of first-trimester placental biomarkers are associated with APOs. However, the patterns vary for different types of APO, indicating heterogeneity in the underlying pathophysiological pathways.
确定五个早孕生物标志物(妊娠相关血浆蛋白 A [PAPP-A]、甲胎蛋白 [AFP]、β人绒毛膜促性腺激素 [β-hCG]、胎盘生长因子 [PlGF]和可溶性 fms 样酪氨酸激酶受体 1 [sFlt-1])与一系列不良妊娠结局(APO)之间的相互关系。
前瞻性队列研究,纳入初产妇单胎妊娠。

在孕 12 周左右测量母体血清中的生物标志物浓度。使用逻辑回归对 APO 进行单变量分析。使用具有交叉验证的最佳子集逻辑回归进行多变量分析。
子痫前期(PE)、小于胎龄儿(SGA),包括严重 SGA(出生体重 <3 个百分位)、胎儿生长受限(FGR)、早产(PTB,包括诱导性和自发性 [iPTB 和 sPTB])、未存活流产和死胎,以及结局组合。
PAPP-A、PlGF 和 sFlt-1 值较低,AFP 值较高与 FGR 相关(1 SD 值升高的 OR 为 0.59 [95% CI 0.48-0.74]、OR 0.56 [95% CI 0.44-0.70]、OR 0.68 [95% CI 0.54-0.87]和 OR 1.53 [95% CI 1.25-1.88])、严重 SGA(OR 0.59 [95% CI 0.49-0.72]、OR 0.71 [95% CI 0.57-0.87]、OR 0.74 [95% CI 0.60-0.91]和 OR 1.41 [95% CI 1.17-1.71])、sPTB(OR 0.61 [95% CI 0.50-0.73]、OR 0.79 [95% CI 0.66-0.96]、OR 0.57 [95% CI 0.47-0.70]和 OR 1.41 [95% CI 1.18-1.67])和 iPTB(OR 0.72 [95% CI 0.57-0.91]、OR 0.62 [95% CI 0.49-0.78]、OR 0.71 [95% CI 0.56-0.90]和 OR 1.44 [95% CI 1.16-1.78])。当评估生物标志物组合时,PAPP-A 和 AFP 与严重 SGA 独立相关;PAPP-A 单独与 PE+PTB 相关;PlGF 单独与严重 PE 相关;PlGF、β-hCG、AFP 和 PAPP-A 与 PE 和 SGA 的组合相关;AFP 和 sFlt-1 与 sPTB 相关;AFP 和 PlGF 与 iPTB 相关。
早孕胎盘生物标志物的组合与 APO 相关。然而,不同类型的 APO 的模式不同,表明潜在的病理生理途径存在异质性。
