Systematic review and meta-analysis: Evaluating the influence of intrahepatic cholestasis of pregnancy on obstetric and neonatal outcomes.

backgroundIntrahepatic cholestasis of pregnancy (ICP) is a serious liver conditions that negatively impacts obstetric and neonatal outcomes. Elevated levels of bile acid, particularly glycine conjugate, may compromise blood flow and cause functional hypoxia-ischemia.

aimsThis meta-analysis aims to assess the association between ICP and key pregnancy outcomes including emergency caesarian sections (C-sections), preeclampsia, hemorrhage, preterm birth, small for gestational age, admission rate to neonatal intensive care union (NICU), gestational age, and stillbirth. MATERIALS AND

methodsLiterature search across five databases (PubMed, Embase, Web of Science) was done to detect relevant studies published up until June 2023. Meta-analysis of the identified studies was done using a random-effects model, and the results presented as Odds ratio (OR).

resultsA literature search identified 662 studies. Of them, 21 met the inclusion criteria. There was a significant association between ICP and odds of C-section (OR: 1.42, p <0.001), preeclampsia (OR: 2.64, p <0.001), NICU admission (OR: 2.1, p <0.001), and pre-term birth (OR: 2.64, p <0.001). ICP was not associated with postpartum hemmorhage (OR: 1.31, p = 0.13), small for gestational age (OR: 0.87, p = 0.07), stillbirth (OR: 1.49, p = 0.29).

conclusionsOur results confirm the adverse effects of ICP on co-existing pregnancy complications, obstetric and neonatal outcomes. ICP in associated with severe complications including increased rates of preeclampsia, emergency C-sections, preterm births, l gestational periods and higher rates of NICU admissions. These results may assist healthcare professionals in formulating comprehensive care guidelines for expectant mothers and newborns.
