Intrahepatic cholestasis of pregnancy

Intrahepatic cholestasis of pregnancy (ICP) is a disease of the third trimester of pregnancy involving pruritus and elevated bile acid levels. Its pathogenesis likely involves a genetic hypersensitivity to estrogen. Once thought to be benign for both mother and fetus, ICP has been associated with increased rates of fetal morbidity and mortality and an increased risk of maternal coagulopathy. Optimal obstetric management includes delivery after establishment of fetal lung maturity. Many treatments have been proposed for the maternal medical management of ICP, none of which is ideal.
