Objectives: Intra-hepatic cholestasis of pregnancy (ICP) is uncommon, but has severe effects on pregnancy outcomes. ICP is characterized by elevated serum bile acids and liver enzymes and preferentially affects women with liver disorders. We compared bile acids and pregnancy outcomes of HIV-infected pregnant women, who commonly have elevated live enzymes, with uninfected controls.

Methods: Twenty-four HIV-infected, including 2 co-infected with hepatitis C virus (HCV), and 25 uninfected women were tested during early and late pregnancy and postpartum.

Results: After exclusion of the HCV-infected women, serum bile acids were similar in HIV-infected and uninfected participants. -glutamyl transpeptidase was elevated in HIV-infected compared with uninfected women during pregnancy and postpartum. Bilirubin and aspartate transaminase were higher in uninfected compared with HIV-infected women in early pregnancy, but subsequently similar. Bile acids in late pregnancy correlated with bile acids in the baby at birth. An HIV- and HCV-co-infected pregnant woman with active hepatitis developed ICP complicated by fetal distress. Another co-infected participant without active hepatitis had an uneventful pregnancy and delivery.

Conclusion: In the absence of HCV co-infection, bile acid metabolism appeared to be similar in HIV-infected and uninfected pregnant women. Both HIV-infected and uninfected pregnant women had mild liver enzyme elevations.
