Plasma HIV RNA levels have been associated with the risk of human papillomavirus (HPV) and cervical neoplasia in HIV-seropositive women. However, little is known regarding local genital tract HIV RNA levels and their relation with cervical HPV and neoplasia.
In an HIV-seropositive women's cohort with semiannual follow-up, we conducted a nested case–control study of genital tract HIV RNA levels and their relation with incident high-grade squamous intraepithelial lesions (HSIL) subclassified as severe (severe HSIL), as provided for under the Bethesda 2001 classification system. Specifically, 66 incidents of severe HSIL were matched to 130 controls by age, CD4+ count, highly active antiretroviral therapy use, and other factors. We also studied HPV prevalence, incident detection, and persistence in a random sample of 250 subjects.
Risk of severe HSIL was associated with genital tract HIV RNA levels (odds ratio comparing HIV RNA ≥ the median among women with detectable levels versus undetectable, 2.96; 95% confidence interval: 0.99 to 8.84; P trend = 0.03). However, this association became nonsignificant (P trend = 0.51) after adjustment for plasma HIV RNA levels. There was also no association between genital tract HIV RNA levels and the prevalence of any HPV or oncogenic HPV. However, the incident detection of any HPV (P trend = 0.02) and persistence of oncogenic HPV (P trend = 0.04) were associated with genital tract HIV RNA levels, after controlling plasma HIV RNA levels.
These prospective data suggest that genital tract HIV RNA levels are not a significant independent risk factor for cervical precancer in HIV-seropositive women, but they leave open the possibility that they may modestly influence HPV infection, an early stage of cervical tumorigenesis.

Abstract presented at the Center For AIDS Research Joint Symposium on HIV Research in Women on September 19, 2012, Providence, RI.
The WIHS is funded by the National Institute of Allergy and Infectious Diseases (UO1-AI-35004, UO1-AI-31834, UO1-AI-34994, UO1-AI-34989, UO1-AI-34993, and UO1-AI-42590) and by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (UO1-HD-32632). The study is cofunded by the National Cancer Institute, the National Institute on Drug Abuse, and the National Institute on Deafness and Other Communication Disorders. Funding is also provided by the National Center for Research Resources (UCSF-CTSI grant number UL1 RR024131). This project has also been funded in part with federal funds from the Frederick National Laboratory for Cancer Research, National Institutes of Health (HHSN261200800001E), the Einstein-Montefiore Center for AIDS Research (5P30AI051519-08), Einstein-Montefiore Clinical and Translational Science Award (1ULIRR025750 and KL2RR025749 to J.G.), and NIAID (R33AI079763 to B.C.H. and R01-CA-085178 to H.D.S.).
