Intrahepatic cholestasis of pregnancy: Review of the literature and evaluation of current evidence

Abstract

Objective: To provide an overview of the epidemiology, etiology, pathogenesis, diagnosis, and management of intrahepatic cholestasis of pregnancy. Methods: We searched the Medline and PubMed database using the key words intrahepatic cholestasis of pregnancy, obstetric cholestasis, diagnosis, management, and complications. Results: Intrahepatic cholestasis of pregnancy, or obstetric cholestasis, is a liver condition that develops during pregnancy. It is associated with increased perinatal morbidity and mortality. Pruritus and risk of postpartum hemorrhage are the main causes of maternal morbidity. Intrahepatic cholestasis of pregnancy is a diagnosis of exclusion. The current management policies depend on regular fetal and maternal monitoring and delivery at fetal maturity. The analysis of the quality of previous studies provided in this review highlights the areas of deficiency in evidence-based knowledge of this subject. Conclusions: More research is required into the etiology, pathogenesis, and monitoring modalities that can specifically predict fetal outcome in intrahepatic cholestasis of pregnancy. Clinical trials are required to identify the most suitable drugs for treatment. © Mary Ann Liebert, Inc.
