Pregnancies of women with chronic kidney disease (CKD) are at higher risk of experiencing adverse perinatal (APO) and maternal outcome (AMO). Mean uterine artery pulsatility index (mUtA-PI) as well as the ratio of soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) are helpful tools in diagnosing pre-eclampsia (PE) in women with CKD. The aim of the study was to evaluate the role of sFlt-1/PIGF ratio and mUtA-PI as predictors for APO, AMO, preterm delivery and decline of kidney function in CKD pregnancies.
A total of 28 CKD pregnancies with suspected PE/HELLP syndrome were retrospectively included, in whom both sFlt-1/PIGF and mUtA-PI were determined during the third trimester. APO was defined as fetal growth restriction, respiratory distress syndrome, intubation, admission to NICU, 5 min Apgar <7 and intracerebral hemorrhage. AMO was defined as the development of PE, HELLP syndrome or resistant hypertension. Decline of kidney function was defined as a 25% increase of creatinine level after delivery.
Of all included women, eight (28.6%) developed a PE/HELLP syndrome. AMO (28.6%) and APO (32.1%) were frequently observed. ROC analyses revealed a predictive value for AMO and sFlt-1/PIGF or mUtA-PI. Neither sFlt-1/PIGF nor mUtA-PI could predict APO or decline of postnatal kidney function. mUtA-PI was a predictor for preterm delivery.
Uterine Doppler and sFlt-1/PIGF are predictors of AMO in CKD pregnancies. Therefore, both markers might be helpful for an improved risk assessment. However, neither sFlt-1/PIGF nor mUtA-PI were able to predict a decline of postnatal kidney function or APO.
患有慢性肾脏病(CKD)的女性的妊娠面临更高的围产期不良结局(APO)和产妇结局(AMO)风险。平均子宫动脉搏动指数(mUtA-PI)以及可溶性 fms 样酪氨酸激酶-1(sFlt-1)与胎盘生长因子(PlGF)的比值有助于诊断 CKD 女性的子痫前期(PE)。本研究旨在评估 sFlt-1/PlGF 比值和 mUtA-PI 作为预测 CKD 妊娠 APO、AMO、早产和肾功能下降的指标的作用。
回顾性纳入 28 例疑似 PE/HELLP 综合征的 CKD 妊娠,其中在妊娠晚期均测定了 sFlt-1/PlGF 和 mUtA-PI。APO 定义为胎儿生长受限、呼吸窘迫综合征、插管、入住新生儿重症监护病房、5 分钟 Apgar 评分<7 和颅内出血。AMO 定义为 PE、HELLP 综合征或难治性高血压的发生。肾功能下降定义为产后肌酐水平升高 25%。
所有纳入的女性中,有 8 例(28.6%)发生了 PE/HELLP 综合征。常观察到 AMO(28.6%)和 APO(32.1%)。ROC 分析显示 AMO 和 sFlt-1/PlGF 或 mUtA-PI 具有预测价值。sFlt-1/PlGF 和 mUtA-PI 均不能预测 APO 或产后肾功能下降。mUtA-PI 是早产的预测因素。
子宫动脉多普勒和 sFlt-1/PlGF 是 CKD 妊娠 AMO 的预测指标。因此,这两种标志物可能有助于改善风险评估。然而,sFlt-1/PlGF 和 mUtA-PI 均不能预测产后肾功能下降或 APO。
