“…However, men taking EFV+3TC+TDF treatment (Efavirenz, Lamivudine, and Zidovudine) did not show a significant increase in CD4+ cells or clearance of HPV infection. This confirms that CD4+ cells are important in eliminating HPV infections [ 123 ].…”

Human papillomavirus (HPV) infection is associated with precancerous lesions and cancer of the genital tract both in women and men. The high incidence of cervical cancer worldwide focused the research on this infection mainly in women and to a lesser extent in men. In this review, we summarized epidemiological, immunological, and diagnostic data associated with HPV and cancer in men. We presented an overview of the main characteristics of HPV and infection in men that are associated with different types of cancer but also associated with male infertility. Men are considered important vectors of HPV transmission to women; therefore, identifying the sexual and social behavioral risk factors associated with HPV infection in men is critical to understand the etiology of the disease. It is also essential to describe how the immune response develops in men during HPV infection or when vaccinated, since this knowledge could help to control the viral transmission to women, decreasing the incidence of cervical cancer, but also could reduce other HPV-associated cancers among men who have sex with men (MSM). Finally, we summarized the methods used over time to detect and genotype HPV genomes, as well as some diagnostic tests that use cellular and viral biomarkers that were identified in HPV-related cancers.

“…Our previous study reported that the use of cART and an increase in CD4 þ T-cell count were associated with lower prevalence of anal infection with high-risk HPV in the same population [36]. In the current study, those with CD4 þ T-cell cell count higher than 500 cells/ml at HIV diagnosis showed lower HPV prevalence, incidence, persistence rate and higher HPV clearance rate.…”

“…A meta-analysis showed that cART was negatively correlated with anal high-risk HPV prevalence in people with HIV [46]. The improvement of the immune function represented by increased CD4 + T-cell count may be helpful in prevention or clearance of HPV infection, which also showed the importance of timely cART treatment in people with HIV [36]. As all participants from this study were under cART, we examined whether different antiviral drugs were associated with HPV incidence or clearance, and no significant association was detected.…”

Objectives: This study aims to estimate the incidence and persistence/clearance of anal HPV infection and related factors among men with HIV in Taizhou, China. Design: A prospective cohort study Methods: Men with HIV were recruited and followed up from 2016 to 2021. Questionnaire surveys were used to collect social-demographic and behavioral characteristics, and anal swabs were collected for HPV Genotyping. Results: A total of 675 men with HIV were recruited and followed up. After an average follow-up time of 1.75 years, HPV39 (3.8/100 person-years), HPV52 (3.6/100 person-years), HPV51 (3.1/100 person-years), HPV58 (2.5/100 person-years) and HPV16 (2.4 cases/100 person-years) in the high-risk types showed the highest incidence rate. In marriage with woman (aHR = 0.44, 95% CI: 0.20–0.99) showed an inverse association with HPV incidence, while bisexuality or undetermined sexual orientation (aHR = 2.62, 95% CI: 1.08–6.36) showed a positive association. For those infected at baseline, the top three high-risk HPV with the lowest clearance density were HPV52 (32.2/100 person-years), HPV58 (38.1/100 person-years), and HPV16 (43.5/100 person-years). Daily consumption of 1–28 grams alcohol (aHR = 0.62, 95% CI: 0.41∼0.95) showed an inverse association with HPV clearance, while illicit drug use (aHR = 3.24, 95% CI: 1.59∼6.59) showed a positive association. Conclusions: Anal HPV infection and clearance were both active in men with HIV in China. Marriage status and sexuality were associated with the incidence of HPV infection, while substance use including alcohol and illicit drug were associated with HPV clearance. More studies are needed to explore the risk factors of HPV persistence.

To understand the HPV infection profiles among Chinese HIV/AIDS patients and the HPV vaccine acceptance among unvaccinated Chinese people with different HIV infection statuses after the HPV vaccine launch in China, this study searched Web of Science, PubMed, Cochrane Library, Embase, Scopus, CNKI, WANFANG, SinoMed, and VIP databases up to 23 June 2023, according to the registered protocol (CRD42023449913). A total of 58 studies were included. The results showed that the HPV infection rate among Chinese HIV/AIDS patients was 52.54% (95% CI: 42.11–62.86%) and higher in males than in females (74.55% vs. 41.04%); meanwhile, the rate was higher in the anus than in the cervix (69.22% vs. 41.71%). Although there was no statistical difference, the high-risk HPV infection rate (38.98%) was higher than low-risk HPV (23.86%), and single infections were more common (28.84%) than multiple infections (19.23%). HPV vaccine acceptance among the unvaccinated Chinese population was 59.19% (95% CI: 52.50–65.89%), and was slightly higher among HIV-infected rather than non-HIV-infected individuals (67.72% vs. 59.58%). There was a difference in acceptance among respondents from different regions. Although the difference in acceptance rate between males and females was not statistically significant (61.10% vs. 61.18%), MSM had a higher acceptance rate than non-MSM (84.28% vs. 59.05%). HPV infection is prevalent among HIV patients, demonstrating the need to increase the frequency of HPV screening for PLWH. The HPV vaccine acceptance rate is higher than that of non-HIV-infected individuals. Male acceptance is almost the same as female’s, with MSM acceptance higher than non-MSM, suggesting that using MSM, especially MSM in PLWH, as an entry point may be a practical avenue to explore to further expand the scope of HPV vaccination.
