[Intrahepatic cholestasis in pregnancy. What to consider in jaundice and pruritus].

Intrahepatic cholestasis of pregnancy is a hepatopathy that occurs in the second or third trimester and accounts for 20% of cases of jaundice occurring in pregnancy. Both genetic and hormonal factors appear to play important roles in its development. The leading symptom is pruritus, and jaundice is common. Transaminases, serum bile acids and bilirubin are typically elevated, while gamma-GT is usually normal. For the differential diagnosis, in particular viral hepatitis, cholelithiasis, gestosis and acute fatty liver of pregnancy must be excluded. While the prognosis of intrahepatic cholestasis of pregnancy for the mother is good, the associated increased tendency for a premature birth represents a potential risk for the child. Early treatment with ursodeoxycholic acid appears to have a positive influence on both the mother's symptoms and the course of the pregnancy. Should the symptoms persist after delivery, consideration must be given to a chronic hepatopathy.
