A Rare Case of Recurrent Intrahepatic Cholestasis of Pregnancy With Prolonged Postpartum Hepatic Inflammation Despite Normalization of Bile Acid Levels.

ABSTRACT

Intrahepatic cholestasis of pregnancy is one of the most common liver diseases during the second and third trimesters of pregnancy, but its pathogenesis remains unclear. Intrahepatic cholestasis of pregnancy is associated with elevations of maternal bile acids, serum aminotransferases, and adverse fetal outcomes. Besides direct cytotoxic liver injury by bile acids, it has been suggested that bile acid-induced oxidative stress and mitochondrial injury lead to a cascade of inflammatory responses. Here, we demonstrate that the extended elevation of serum aminotransferases after normalization of bile acid levels coincides with an extended increase of the chemokine CXCL10 and inflammatory cytokines.
