Effect of intrahepatic cholestasis of pregnancy on maternal serum screening tests

Diagnostic and prognostic value of blood inflammation and biochemical indicators for intrahepatic cholestasis of pregnancy in Chinese pregnant women

Intrahepatic cholestasis of pregnancy (ICP) is a common liver disease during pregnancy, that has serious complications. This study aimed to compare the blood inflammation and biochemical markers of pregnant women with ICP in Southwest China and analyse their diagnostic value for ICP. A controlled cross-sectional study was conducted, and routine blood and biochemical indicators of 304 diagnosed ICP patients and 363 healthy pregnant women undergoing routine prenatal examination were assessed. The blood inflammatory indicators and biochemical indicators were compared between the ICP groups and normal groups. In this study, the levels of the ALT, AST, GGT, TBIL and DBIL biochemical indicators and the levels of WBC, neutrophils, NLR and PLR inflammatory indicators in the ICP group were significantly higher than those in healthy pregnant women (p < 0.001). The PA and lymphocytes of the ICP group were significantly lower than those of the normal group (p < 0.001). ROC curves showed that ALT and the NLR had higher predictive value for ICP. The GGT, TBA and NLR of pregnant women with ICP in the preterm group were significantly higher than those in the term group, and the combined NLR and TBA had a certain predictive value for preterm birth.

Effects of intrahepatic cholestasis of pregnancy on hepatic function, changes of inflammatory cytokines and fetal outcomes

The effects of intrahepatic cholestasis of pregnancy (ICP) on hepatic function, changes of inflammatory cytokines and fetal outcomes were studied. In total, 663 pregnant women admitted to Daqing Longnan Hospital from July 2016 to December 2017 were selected. There were, 40 cases with ICP enrolled in the observation group, and 40 normal pregnant women were recruited in the normal group. They were also grouped according to hepatic function and inflammatory cytokines, with 40 cases in each group. Neonatal Apgar scores were recorded. The correlations of serum cholylglycine (CG) in pregnant women with umbilical artery systolic-to-diastolic (S/D) ratio in the third trimester of pregnancy, the alanine aminotransferase level, the high-sensitivity C-reactive protein (hs-CRP) level, neonatal Apgar score and gestational week were analyzed. The birth weight in the observation group was lighter than that in the normal group (P<0.05); the gestational week at birth was earlier than that in the normal group (P<0.05); Apgar score at birth was lower than that in the normal group (P<0.05), and the levels of inflammatory cytokines were higher than those in the control group (P<0.05). Apgar scores of newborns at birth and at 1 and 5 min after birth in the normal hepatic function and normal inflammatory cytokine groups were higher than those in the abnormal hepatic function group (P<0.05). The serum CG level in pregnant women was positively correlated with umbilical artery S/D ratio, the alanine aminotransferase level and the hs-CRP level in the third trimester of pregnancy, but negatively correlated with neonatal Apgar score and gestational week. Among patients with ICP, the higher the GG level in the body is, the higher the alanine aminotransferase, inflammatory cytokine and umbilical artery S/D ratio will be, which may cause lower neonatal Apgar score, neonatal asphyxia and premature delivery.
