Certain human genital papillomaviruses (HPV) are strongly associated with cervical dysplasia and cancer. Evidence is accumulating that HPV infection and ano-genital cancers are more common in patients with the acquired immunodeficiency syndrome. The objective of our study was to evaluate the extent to which HPV infection and associated cervical disease constitute opportunistic complications of human immunodeficiency virus (HIV) infection in a population of sexually promiscuous, HIV-infected women in Kinshasa, Zaire. In 1989 we obtained Pap smears and cervicovaginal lavage specimens for HPV DNA testing from 47 HIV-seropositive and 48 HIV-seronegative prostitutes who were part of a cohort under observation since 1988. Thirty-eight percent of the HIV-seropositive and 8% of the seronegative women (odds ratio = 6.8; p = 0.001) had HPV DNA detected by either ViraType, a dot-blot assay which detects specific genital HPV types, or low-stringency Southern blot, which detects all HPV types. Eighty-two women (86%) had an interpretable Pap smear; 11 of 41 (27%) HIV-seropositive women and one of 41 (3%) seronegative women had cervical intra-epithelial neoplasia (CIN) (odds ratio = 14.7; p = 0.002). HIV seropositivity, HPV infection and CIN were highly associated. Eight (73%) of 11 seropositive women with CIN had HPV detected. Both HPV infection and cervical cancer may emerge as opportunistic complications of HIV infection in populations in which HIV, HPV and cervical cancer are common.
Cericovaginal lavage samples from 124 human immunodeficiency virus type 1 (HIV-1)-seropositive and 126 HIV-1-seronegative women were collected monthly for 8 months and tested for human papillomavirus (HPV) DNA. The estimated prevalence of HPV was 42.8% in HIV-1-seropositive and 13.4% in -seronegative women (P < .001). There was no significant difference in HPV DNA detection in HIV-1-seropositive women with CD4 cell counts of < 300/mm3 (50% HPV-positive), 300-499/mm3 (36.4% HPV-positive), or > or = to 500/mm3 (40.5% HIV-positive). However, HIV-1-seropositive women who were more immunocompromised, as indicated by lower CD4 cell counts, were more likely to shed HPV persistently. The quantity of HPV DNA detected in cervicovaginal lavage samples was similar in HIV-1-seropositive and -seronegative women. This study further defined the characteristics of HPV infections in HIV-1-infected women.
Human papillomavirus (HPV) DNA was found in cervicovaginal lavage fluids from 9 of 11 human immunodeficiency virus type 1 (HIV-1)-seropositive female prostitutes with cervical intraepithelial neoplasia (CIN) in Kinshasa, Zaire. Since 7 yielded complex nucleic acid hybridization results consistent with mixed HPV infections, limited sequencing of HPV DNA was used to identify the HPVs present. Three of HPV 16 and 1 each of HPV 18, 31, 33, and 56 and ME180-HPV were identified by sequencing in 8 samples. Each of these genotypes has been found in specimens from HIV-1-seronegative women with CIN. Some DNAs had nucleic acid and amino acid sequence variations relative to the reference HPVs, but the variants were closely related to variants that have been found in HIV-1-seronegative women. Variant amino acids were found predominantly at three positions in one 40-amino-acid segment of the L1 open reading frame sequenced. The predominant HPV 16 variant observed has been found rarely in other countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
