Abstract

Intrahepatic cholestasis of pregnancy (ICP) is a reversible pregnancy-specific cholestatic condition characterized by pruritus, elevated liver enzymes, and increased serum bile acids. It commences usually in the late second or third trimester, and quickly resolves after delivery. The incidence is higher in South American and Scandinavian countries (9.2%-15.6% and 1.5%, respectively) than in Europe (0.1%-0.2%). The etiology is multifactorial where genetic, endocrine, and environmental factors interact. Maternal outcome is usually benign, whereas fetal complications such as preterm labor, meconium staining, fetal distress, and sudden intrauterine fetal demise not infrequently lead to considerable perinatal morbidity and mortality. Ursodeoxycholic acid is shown to be the most efficient therapeutic agent with proven safety and efficacy. Management of ICP consists of careful monitoring of maternal hepatic function tests and serum bile acid levels in addition to the assessment of fetal well-being and timely delivery after completion of fetal pulmonary maturity. This review focuses on the current concepts about ICP based on recent literature data and presents an update regarding the diagnosis and management of this challenging issue.

Core tip: Intrahepatic cholestasis of pregnancy (ICP) is a unique hepatic disorder in pregnancy characterized by pruritus, elevated liver enzymes, and serum bile acids. It usually appears in the third trimester and dissolves rapidly after delivery. The incidence is variable between 0.1%-15.6% in different geographic regions of the world. Genetic, hormonal, and environmental factors interact in its etiopathogenesis. A considerable incidence of perinatal morbidity-mortality makes it one of the most concerning obstetric entities for obstetricians and critical care specialists. Timely diagnosis and expert multidisciplinary management of pregnant women with ICP is mandatory to ensure a favorable maternal-fetal outcome.
