Prevalence of human papilloma virus infection and anal dysplasia among men with HIV in Lebanon: a cross-sectional study

Abstract

Background Oncogenic human papillomavirus (HPV) types are linked to anal cancer, with elevated risk among men who have sex with men (MSM), especially men with HIV. Data on HPV-related malignancies in the Middle East and North Africa (MENA) region is scarce. This study aims to assess anal HPV strains, dysplasia, and sexually transmitted infections (STIs) among asymptomatic MSM with HIV in Lebanon. Methods We conducted a cross-sectional study with 38 participants who completed questionnaires on socio-demographics, HIV-related data, and STI history. Anoscopy, anal Pap smears, and PCR for HPV and STIs were performed. Results HPV was detected in 34 of 38 samples (89%), with 91% having multiple strains. HPV16 was the most common strain (56%). Eighteen percent had a concomitant bacterial anal STI. Most participants lacked awareness of anal dysplasia and cancer risk, with only 29% vaccinated against HPV. Conclusion This study highlights high HPV prevalence and low awareness among men with HIV in Lebanon. The findings underscore the need for improved HPV education, vaccination, and routine screening in this population. Further research is needed to address barriers to comprehensive HIV and STI care in the region.
