Pregnancy and primary biliary cirrhosis.

Pregnancy is rarely encountered in patients with primary biliary cirrhosis. Ten pregnancies in nine patients have been reported in the literature. All five pregnancies that continued beyond the 31st week had increasing jaundice during late pregnancy. We describe a case of primary biliary cirrhosis with symptomatic onset at age 19, pregnancy a year later, with subsequent resolution of jaundice and pruritus. This course is different than most described by others.
