Introduction: Intrahepatic cholestasis of pregnancy (ICP) is a liver disease that occurs during pregnancy. While ICP has a minimal impact on the mother, it primarily affects the pregnancy outcome of fetus, resulting in spontaneous miscarriage and even the intrauterine death of fetus.
Areas covered: This review covers current progress in the role of gut microbiota and bile acids in ICP.
Expert opinion: The causes and pathogenesis of ICP are currently unclear, and the serum bile acid level is the main clinical evidence for ICP diagnosis. The gastrointestinal tract is home to a tremendous number and type of microbes, which play critical roles in the synthesis and metabolism of bile acids. Studies in recent years have shown that the changes in gut microbiota and bile acid metabolic profiles are closely associated with ICP. This review discusses some of the future prospects in this area of research.
Keywords: Intrahepatic cholestasis of pregnancy; bile acid; bile acid metabolism; dysbacteriosis; gut microbiota.
