Intrahepatic cholestasis of pregnancy

Intrahepatic cholestasis of pregnancy is the most common Liver disorder unique to pregnancy in women without hypertension. The cause of intrahepatic cholestasis of pregnancy is still under discussion but genetic and hormonal factors are predominant. The main symptom is skin pruritus, associated with increase in serum transaminase activities and bite acid concentrations. Intrahepatic cholestasis of pregnancy carries a risk for the pregnancy because of preterm delivery and sudden intrauterine fetal death. Ursodeoxycholic acid (usually 1000 mg per day or 15 mg/kg per day) is currently the most effective pharmacologic treatment. Ursodeoxycholic acid reduces pruritus, transaminases and bile acid Levels and probably prematurity without adverse effects. Obstetric management is still under debate. The majority of authors recommend active management with elective delivery usually before or at 38 weeks of gestation according the severity of cholestasis. Prospective controlled studies are required to confirm the benefit of ursodeoxycholic acid treatment on fetal outcome and to clarify the obstetrical management near term.
