- Abstract
Objective: We sought to examine the impact of the loop electrosurgical excision procedure (LEEP) on the rate and magnitude of HIV-1 genital shedding among women undergoing treatment for cervical intraepithelial neoplasia 2/3 (CIN2/3)., Design: Prospective cohort study., Population: Women infected with HIV-1 undergoing LEEP for CIN2/3 in Kisumu, Kenya., Methods: Participants underwent specimen collection for HIV-1 RNA prior to LEEP and at 1, 2, 4, 6, 10, and 14 weeks post-LEEP. HIV-1 viral load was measured in cervical and plasma specimens using commercial real-time polymerase chain reaction (PCR) assays, to a lower limit of detection of 40 copies per specimen., Main Outcome Measures: Presence and magnitude of HIV-1 RNA (copies per specimen or cps) in post-LEEP specimens, compared with baseline., Results: Among women on highly active antiretroviral therapy (HAART), we found a statistically significant increase in cervical HIV-1 RNA concentration at week 2, with a mean increase of 0.43 log10 cps (95% CI 0.03-0.82) from baseline. Similarly, among women not receiving HAART, we found a statistically significant increase in HIV-1 shedding at week 2 (1.26 log10 cps, 95% CI 0.79-1.74). No other statistically significant increase in concentration or detection of cervical HIV-1 RNA at any of the remaining study visits were noted., Conclusions: In women infected with HIV undergoing LEEP, an increase in genital HIV shedding was observed at 2 but not at 4 weeks post-procedure. The current recommendation for women to abstain from vaginal intercourse for 4 weeks seems adequate to reduce the theoretical increased risk of HIV transmission following LEEP., (© 2013 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2013 RCOG.)

- Abstract
HIV-1 genital shedding is associated with increased HIV-1 transmission risk. Inflammation and ulceration are associated with increased shedding, while highly active antiretroviral therapy (HAART) has been shown to have a protective effect. We sought to examine the impact of cervical biopsies, a routine component of cervical cancer screening, on HIV-1 genital RNA levels in HIV-infected women on HAART. We enrolled HIV-1-infected women undergoing cervical biopsy for diagnosis of cervical intraepithelial neoplasia (CIN) 2/3 in this prospective cohort study. All were stable on HAART for at least 3 months. Clinical and demographic information as well as plasma HIV-1 viral load were collected at the baseline visit. Specimens for cervical HIV-1 RNA were collected immediately prior to biopsy, and 2 and 7 days afterward. Quantitative PCR determined HIV-1 concentration in cervical specimens at each time point to a lower limit of detection of 40 copies/specimen. Among the 30 participants, five (16.6%) women had detectable cervical HIV-1 RNA at baseline, of whom four (80%) had detectable HIV-1 RNA after cervical biopsy, with no significant increase in viral load in the follow-up specimens. Only one woman (3.3%) with undetectable baseline cervical HIV-1 RNA had detection postbiopsy. Detectable plasma HIV-1 RNA was the only factor associated with baseline cervical HIV-1 RNA. In women on HAART, an increase in cervical HIV-1 RNA detection or concentration was not associated with cervical biopsy. These findings help provide safety data regarding cervical cancer screening and diagnosis in HIV-infected women and inform postprocedure counseling.

- Abstract
Objective: Given the high prevalence of cervical intraepithelial neoplasia (CIN) grade 2/3 among HIV-infected women, we sought to examine the relationship between CIN 2/3 and HIV-1 genital shedding among women on highly active antiretroviral therapy (HAART)., Materials and Methods: Paired plasma and cervical wick specimens for HIV-1 RNA measurements were obtained from 44 HIV-infected women with biopsy-confirmed CIN 2/3 (cases) and 44 age-matched HIV-infected women with normal cervical findings on colposcopy (controls). All subjects tested negative for sexually transmitted infections and had been stable on HAART for at least 3 months. HIV-1 viral load was measured in both blood and cervical specimens using commercial real-time polymerase chain reaction assays., Results: Cervical intraepithelial neoplasia 2/3 was not significantly associated with the detection or magnitude of plasma or cervical HIV-1 RNA shedding. HIV was detected in the plasma in 10 cases (23%) and 10 controls (25%) (odds ratio = 1.0; 95% confidence interval = 0.33-3.1). Cervical HIV-1 was detected in 6 cases (13.6%) and 9 controls (20.4%) (odds ratio = 0.61; 95% confidence interval = 0.20-1.90). Mean HIV-1 concentration in cervical secretions among women with CIN 2/3 who shed was 2.93 log10 copies versus 2.72 among controls (p = .65)., Conclusions: Among women on HAART, we found no relationship between CIN 2/3 and HIV-1 genital shedding.
