Factors Affecting the Prognosis of Women with Liver Dysfunction in the Third Trimester of Pregnancy / 中山大学学报(医学科学版)

ABSTRACT

@#【Objective】To explore the effects of liver dysfunction in the third trimester of pregnancy on maternal outcomes and identify the factors affecting the maternal prognosis.【Methods】We collected the clinical data of 1 113 women with liver dysfunction in the third trimester of pregnancy （case group） and 1 113 normal pregnancies （control group） from the Third Affiliated Hospital of Sun Yat-sen University between January 2015 and December 2018. We compared the rates of cesarean section，premature delivery，placental abruption，postpartum hemorrhage and maternal mortality in the two groups，conducted the univariate and multivariate analysis for the case group and determined the prognostic risk factors by using Logistic regression. Receiver operating characteristic（ROC）curve analysis was applied to estimate the value of each independent risk factor for predicting liver dysfunction-related maternal mortality. 【Results】The rates of cesarean section，premature delivery，placental abruption，postpartum hemorrhage in the case group were higher than those in the control group（P < 0.05），and the odds ratios（ORs）were 3.59 ，7.81 ，10.68 and 2.93 ，respectively. The maternal mortality in the case group（1.2%）was higher than that in the control group（0.0%）（P < 0.05）. Logistic analysis revealed that high total bilirubin（TBIL），low prothrombin activity（PTA）and low fasting plasma glucose（FPG）were independent risk factors for liver dysfunction- related maternal mortality. The ROC curve analysis indicated that when TBIL was 235.4 μmol/L，the Youden′ s index in maximum was 0.331 with sensitivity of 0.818 and specificity of 0.513. When PTA was 20.5% ，the Youden′ s index in maximum was 0.366 with sensitivity of 0.821 and specificity of 0.545. When FPG was 3.11 mmol/L，the Youden′s index in maximum was 0.405 with sensitivity of 0.769 and specificity of 0.636.【Conclusion】Liver dysfunction in the third trimester of pregnancy has adverse effects on maternal outcomes. TBIL ，PTA and FPG are the factors affecting the maternal prognosis and may have certain predictive value for maternal death.
