Intrahepatic cholestasis of pregnancy (ICP), also called obstetric cholestasis, is the most common pregnancy-specific liver disease. Classic symptoms include generalized pruritus that commonly includes the palms and soles, and biochemical evidence of elevated bile acids, with or without elevated liver function tests (LFTs). The etiology of ICP is influenced by a combination of genetic, endocrine, and environmental factors. Risk factors for ICP include multiple pregnancy, in vitro fertilization, advanced maternal age, history of prior affected pregnancy, positive family history, and hepatitis C infection.
