BACKGROUND Human immunodeficiency virus (HIV)-seropositive men who have sex with men (MSM) are at higher risk of human papillomavirus (HPV) infection. This study was conducted to better understand the natural history of type-specific HPV infection in the anus. METHODS A cohort study was conducted among HIV-seropositive MSM in Montreal to investigate(More)
BACKGROUND Human immunodeficiency virus (HIV)-seropositive men who have sex with men (MSM) are at risk for anal intraepithelial neoplasia (AIN) and cancer. The goal of this study was to identify risk factors associated with high-grade AIN (AIN-2,3) in HIV-positive MSM, including the receipt of highly active antiretroviral therapy (HAART). METHODS A cohort(More)
A novel real-time PCR assay for detection of human papillomavirus type 52 (HPV-52) DNA (RT-52) was evaluated on 265 anogenital samples. RT-52 had a sensitivity of 98.4% and a specificity of 100% compared to conventional HPV-52 typing assays, including hybridization of PGMY products with an HPV-52-specific probe and PCR sequencing of HPV-52 E6.
OBJECTIVES To assess levels of episomal and integrated human papillomavirus type 16 (HPV-16) loads in HIV-seropositive men who have sex with men (MSM) in anal infection and to study the association between episomal and integrated HPV-16 loads and anal intraepithelial neoplasia (AIN). STUDY DESIGN A cohort study of 247 HIV-positive MSM followed each 6(More)
BACKGROUND The current goal of antiretroviral therapy (ART) is to maintain a suppressed human immunodeficiency virus (HIV) viral load below limits of assay detection. When viral loads remain in low-level viremia (LLV), especially between 50 and 200 copies/mL, the best management and clinical consequences remain unknown. Our objective was to study the(More)

BACKGROUND CD8 T-cell counts remain elevated in human immunodeficiency virus (HIV) infection even after long-term antiretroviral therapy (ART), which is associated with an increased risk of non-AIDS-related events. We assessed the impact of ART initiation in early versus chronic HIV infection on trajectories of CD8 cell counts over time. METHODS Of 280(More)
Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected(More)
Studies conducted in HIV-seropositive individuals have enhanced our understanding of the natural history of anal intraepithelial neoplasia (AIN) and of factors predictive of progression to high-grade AIN, the immediate precursor to anal cancer. AIN is frequently detected in HIV-seropositive individuals. Factors that increase the risk for AIN include HIV(More)
INTRODUCTION The increasing proportion of women living with HIV has evoked calls for tailored services that respond to women's specific needs. The objective of this investigation was to explore the concept of women-specific HIV/AIDS services to identify and define what key elements underlie this approach to care. METHODS A comprehensive review was(More)
