The purpose of this study was to compare alpha-fetoprotein, human chorionic gonadotropin, and unconjugated estriol levels in women who take protease inhibitors and those women who do not. This retrospective review from August 2000 to May 2003 was performed for maternal serum screen results, medication use, pregnancy, and perinatal outcomes. Thirty-nine women met study criteria. Sixteen women were treated with protease inhibitors, and 23 women were not treated with protease inhibitors. There was no difference in initial viral load or initial CD4 count between the groups. No difference was found for human chorionic gonadotropin and estriol levels; significantly lower alpha-fetoprotein multiples of the median were found for the women who were treated with protease inhibitors compared with the women who were not (0.97 ± 0.32 [SD] MoM vs 1.2 ± 0.4 MoM, respectively; P =. 04). Six of 39 women (15%) had positive maternal serum screens. All the babies were normal at birth, and there were no cases of perinatal transmission of human immunodeficiency virus. Protease inhibitors are associated with lower alpha-fetoprotein levels in women who are infected with human immunodeficiency virus.
