Abstract

OBJECTIVE:

To assess toxicities associated with highly active antiretroviral therapy (HAART) among HIV-1-infected pregnant women treated with nevirapine-based regimens according to Mozambican national guidelines.

STUDY DESIGN:

Prospective cohort study.

METHODS:

HIV-1-infected antiretroviral-naive pregnant women with CD4 counts < or =350 cells/microL were initiated on nevirapine, lamivudine, and stavudine or zidovudine and followed monthly. Severe hepatotoxicity was defined as aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels > or =5-fold the upper limit of normal. Analyses were stratified by baseline CD4 count (<250 vs. 250-350 cells/microL).

RESULTS:

Among 146 pregnant women, 75 (52%) began nevirapine, lamivudine, and zidovudine and 71 (48%) began nevirapine, lamivudine, and stavudine. Overall, 79 (54%) women had CD4 counts <250 cells/microL, 7 (5%) had grade II hepatotoxicity, and 4 (3%) had severe (grade III or IV) hepatotoxicity. All 4 women with severe hepatotoxicity had baseline CD4 counts > or =250 cells/microL (P = 0.02). Rates of skin toxicity, anemia, and peripheral neuropathy did not differ by CD4 cell count group. Overall, 12 (8%) women changed or discontinued HAART as a result of drug toxicity.

CONCLUSIONS:

Severe hepatotoxicity from nevirapine-containing HAART in this cohort of pregnant women was more common at higher CD4 counts (6% vs. 0% among women with CD4 counts > or =250 cells/microL and CD4 counts <250 cells/microL, respectively), suggesting that laboratory monitoring is necessary when administering nevirapine-containing regimens to pregnant women with CD4 counts > or =250 cells/microL.
