Hepatic disease in pregnancy.
Liver disease occurring in pregnancy can be categorized into three groups. The first group includes diseases unique to pregnancy and caused by it. Among these are hyperemesis gravidarum, cholestasis of pregnancy, and disorders associated with preeclampsia. Liver involvement may be expected in 50% of patients with hyperemesis gravidarum. Preeclampsia has been associated with both the HELLP syndrome (hemolysis, elevated liver tests, and low platelets), which includes hepatic infarction and rupture, and with acute fatty liver of pregnancy (AFLP). In patients with HELLP syndrome, liver test abnormalities do not correlate with liver injury. Therefore, this and other disorders associated with preeclampsia require aggressive treatment, primarily with delivery. The second group of liver diseases are those exacerbated by pregnancy. Viral infections involving the liver that are usually benign, such as hepatitis E and herpes simplex, are more likely to be exacerbated in pregnant women and are more likely to lead to fulminant hepatic failure. Cholelithiasis and Budd-Chiari syndrome are more prevalent in pregnant women. The third group is comprised of liver diseases that are preexisting in the pregnant patient and includes autoimmune chronic active hepatitis and Wilson's disease. The number of patients in the last group is small, as chronic liver disease is rare in women who are able to bear children.
