Medical and Obstetric Complications Among Pregnant Women With Liver Cirrhosis
To evaluate clinical characteristics and obstetric outcomes in pregnant women with liver cirrhosis.METHODS:
This was a retrospective matched cohort study of women with liver cirrhosis between January 2005 and January 2016 in a university hospital. Women in a case group were matched to women in a control group according to year of delivery, age, body mass index, and parity in a 1:4 ratio. Bivariable and multivariable analyses were performed to compare the prevalence of the primary composite outcome, which included any one of the following: fetal or neonatal demise, placental abruption, preeclampsia, preterm delivery at less than 37 weeks of gestation, and small-for-gestational age neonate between women in the case group and those in the control group.RESULTS:
During the study period, the number of deliveries was approximately 110,000. Of these, 33 women with liver cirrhosis were identified, yielding an estimated frequency of cirrhosis of 1 per 3,333 pregnancies [95% confidence interval (CI) 3,313–3,353]. Thirty-one of these 33 women met all inclusion criteria. The most common etiology of cirrhosis was alcoholic liver disease. The rate of the primary outcome was 61% in women with cirrhosis and 12% in women in the control group. There were no cases of maternal death, and the livebirth rate was 97%. Women with cirrhosis were more likely to be non-Hispanic black, have chronic hypertension, and use alcohol. Multivariable logistic regression demonstrated that cirrhosis in pregnancy was associated with the composite outcome (adjusted odds ratio 9.4, 95% CI 3.4–26.2).CONCLUSION:
Despite lower rates of maternal and fetal mortality compared with earlier studies, pregnancy in women with liver cirrhosis is still associated with a high risk of adverse obstetric outcomes.
