High-risk HPV detection via GeneXpert in self-collected anal swabs among MSM living with HIV: Insights from a cross-sectional study
Year: 2026
Type: article
Study design: Observational Study
Abstract: Background: Men who have sex with men living with HIV (MSMLWHIV) have a high risk of persistent high-risk HPV infection, and rapid tools like Xpert HPV can help expand screening in low-resource settings. Objectives: This study aimed to assess the feasibility of using self-collected anal swabs for detecting high-risk human papillomavirus (HR-HPV) infections in MSMLWHIV, using the Xpert® HPV assay. Additionally, we investigated factors associated with HR-HPV positivity. Design: July 2024 among MSMLWHIV in Bamako. Methods: Participants were recruited from the Soutoura NGO in Bamako, Mali. To be eligible, individuals had to be HIV-1 positive, on antiretroviral therapy, 18 years or older, and self-identified as MSM. The prevalence of HR-HPV was reported by sociodemographic characteristics and sexual behaviors. We used a penalized logistic regression model using Firth's method to identify sociodemographic and behavioral factors associated with HR-HPV positivity. Results: A total of 245 MSMLWHIV were initially tested. Of these, 170 yielded successful results and were subsequently included in the study analysis. The participants had a median age of 26 years (IQR 24-29) with the median age of first anal intercourse at 16 years (IQR 16-18). Among the participants, 29% (49/170) identified as bisexual, 42% (72/170) reported never using condoms, 16% (27/170) participated in group intercourse, and 42% (71/170) had at least two different sexual partners in the past six months. Among those successfully tested, 65% (110/170) were positive for HR-HPV, with HPV16 detected in 12% (21/170) of participants. No or primary education and consistent condom use were associated with lower odds of HR-HPV positivity, while the unexpected association observed with smoking should be interpreted with caution. Conclusion: The high HR-HPV prevalence among MSMLWHIV calls for targeted screening and prevention. Although Xpert HPV shows promise, the 31% failure rate with self-collected samples underscores the need for improvements in sample collection procedures and technical performance.
