Outcomes of pregnancy in Child A liver cirrhotic patients: A retrospective multicenter study

Pregnancy in women with liver cirrhosis is associated with increased risk for complications: A systematic review and meta-analysis of the literature

BACKGROUND

Pregnancy and liver cirrhosis is a rare but increasing combination. Liver cirrhosis can raise the chance of maternal and fetal mortality and morbidity, although the exact risks remain unclear.

OBJECTIVE

To provide a systematic literature review and meta-analysis on maternal, fetal and obstetric complications among pregnant women with liver cirrhosis.

SEARCH STRATEGY

We performed a systematic literature search in the databases PubMed/MEDLINE and EMBASE (Ovid) from inception through 25 January 2021.

SELECTION CRITERIA

Studies including pregnancies with liver cirrhosis and controls were eligible.

DATA COLLECTION AND ANALYSIS

Two reviewers independently evaluated study eligibility. We used the random effects model for meta-analysis.

MAIN RESULTS

Our search yielded 3118 unique papers. We included 11 studies, including 2912 pregnancies in women with cirrhosis from 1982-2020. Seven studies were eligible for inclusion in the meta-analysis. The overall maternal mortality rate was 0.89%. Maternal mortality and variceal haemorrhage were lower in recent than in older studies. Most cases of maternal mortality due to variceal haemorrhage (70%) occurred during vaginal delivery. Pregnant women with liver cirrhosis had a higher chance of preterm delivery (OR 6.7, 95% CI 5.1-9.1), caesarean section (OR 2.6, 95% CI 1.7-3.9), pre-eclampsia (OR 3.8, 95% CI 2.2-6.5) and small-for-gestational-age neonates (OR 2.6, 95% CI 1.6-4.2) compared with the general obstetric population. Subgroup analyses could not be conducted.

CONCLUSIONS

Liver cirrhosis in pregnant women is associated with increases in maternal mortality and obstetric and fetal complications. Large international prospective studies are needed to identify risk factors for unfavourable outcome.
