title: Virus excretion in the cervicovaginal secretions of pregnant and nonpregnant HIV-infected women.
abstract: In order to estimate the prevalence of viral excretion in cervicovaginal secretions, we made a cross-sectional study of 55 HIV-infected women. The patient population was diverse, including pregnant and nonpregnant women in different disease stages from three centers. Virus replication was found in the cell-free supernatant from 12 of 55 cervicovaginal samples (21.8%) by coculture on the CD4-positive cell line CEM-C113. In addition, cell-associated virus was detected in five of a subgroup of 22 samples testing negatively on cell-free supernatant. The prevalence of HIV in the cell-free supernatant was not related to disease stage, zidovudine therapy, transmission group, or history of sexually transmitted diseases. Excretion of HIV was significantly higher in our population of pregnant women (eight of 21, 38%) compared with an unmatched group of nonpregnant women (four of 34, 11.8%; p = 0.04). These results provide evidence of cell-free virus shedding as well as the presence of cell-associated virus in the genital secretions of HIV-infected women.
