Summary
This study aimed to identify biochemical predictors of adverse perinatal outcomes in intrahepatic cholestasis of pregnancy (ICP). A total of 106 ICP cases were analyzed retrospectively by the combination of receiver operating characteristic curve and binary logistic regression analysis. “Adverse perinatal outcomes” included spontaneous preterm labor, meconium-staining of amniotic fluid, stillbirth and Apgar score ≤7 at 1 or 5 min. Total bile acid (TBA) [AUC=0.658, 95%CI (0.536, 0.781), P=0.031] was a valuable predictor for adverse perinatal outcomes. The critical value of TBA above which adverse perinatal outcomes were observed was 40.15 μmol/L (Youden’s index=0.3). Binary multivariate logistic regression analysis revealed that the risk of adverse perinatal outcomes increased when TBA ≥40.15 μmol/L [OR=3.792, 95%CI (1.226, 11.727), P=0.021]. It is concluded that the risk of adverse perinatal outcomes in ICP increases when maternal TBA ≥40.15 μmol/L.
