Nevendorff L, Schroeder SE, Pedrana A, Bourne A, Stoové M. Prevalence of sexualized drug use and risk of HIV among sexually active MSM in East and South Asian countries: systematic review and meta-analysis. J Int AIDS Soc 2023; 26:e26054. [PMID: 36600479 DOI: 10.1002/jia2.26054] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 12/05/2022] [Indexed: 01/06/2023] Open
Abstract
INTRODUCTION Sexualized drug use (SDU), the use of psychoactive drugs in the context of sexual intercourse, has been identified as a risk factor for HIV among men who have sex with men (MSM) in Asia. Given the distinct social and cultural context of same-sex relationships and drug-using practice in Asia, we aimed to describe the prevalence of SDU in East and South Asian countries and its associations with condomless anal sex (CAI) and HIV status. Synthesizing SDU research in this region, including SDU definitions, prevalence and outcomes, provides insights to inform future research and improved programme planning, resourcing and advocacy. METHODS We systematically searched OVID Medline, OVID EMBASE, OVID Global Health, CINAHL, PsycINFO and SCOPUS publication databases for scientific articles published from 1990 to 2022 measuring SDU among MSM in East and South Asian countries. A narrative synthesis was utilized to describe key study attributes and findings, and meta-analyses using random pooled effect models were used to estimate SDU prevalence and its associations with CAI and HIV status. Subgroup meta-analyses, sensitivity analysis and assessment of publication bias examined potential sources of heterogeneity for the pooled SDU prevalence estimates. RESULTS AND DISCUSSION Of the 1788 publications screened, 49 publications met the selection criteria and 18 were suitable for meta-analyses. Findings highlight SDU definitions distinct from other regions but inconsistencies in the definition of SDU between studies that have been highlighted in research elsewhere. The pooled prevalence of recent SDU (past 12 months) was 13% (95% CI = 10-16%; I2 = 97.6) but higher when studies utilized self-administered surveys (15%; 95% CI = 12-19%; p<0.05). SDU was associated with greater odds of CAI (pooled odds ratio [OR] = 3.21; 95% CI = 1.82-5.66) and living with diagnosed HIV (OR = 4.73; 95% CI = 2.27-8.21). CONCLUSIONS SDU is common among MSM in East and South Asian countries, but varying SDU definitions limit between-study comparisons. Responses to SDU-related harms should consider local contexts, including specific drug types used and their relative risks.

Abstract
Men who have sex with men (MSM) are at high risk of infection with human papillomavirus (HPV). Some countries have incorporated MSM into their HPV vaccination strategies. The acceptance of the HPV vaccine is an important factor affecting vaccine promotion in MSM. This study aims to analyze the factors influencing HPV vaccination willingness among MSM in China. Non-probability sampling was used to recruit MSM in China in June 2021. The information collected included demographic characteristics, HPV knowledge, attitude, behavior, history of sexually transmitted diseases (STDs), and HPV vaccination intention. A structural equation model was used to analyze the data based on the theory of knowledge-attitude-behavior. Among 889 participants, 736 (82.79%) of the MSM were willing to receive the HPV vaccine. The results of the structural equation model showed that knowledge, attitude, behavior, and STD history influenced the vaccination intention, of which knowledge (total effect of .36) and attitude (total effect of .31) had the greatest influence. Since most MSM in China were willing to be vaccinated against HPV, they should be considered for inclusion in the HPV vaccination program. Enhancing HPV awareness and improving risk awareness may be useful in increasing the vaccination willingness of MSM in China.

Front Public Health 2022; 10:896479. [PMID: 35923960 PMCID: PMC9340213 DOI: 10.3389/fpubh.2022.896479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 06/22/2022] [Indexed: 11/29/2022] Open
Abstract
Objectives Reinfection of human papillomavirus (HPV) among men who have sex with men (MSM) after clearing the infection of HPV has not been well characterized. To understand the reinfection of HPV among human immunodeficiency virus (HIV) negative MSM without HPV vaccine, we analyzed the reinfection of nine-valent HPV vaccine (9v-HPV) types. Methods Data were acquired from a prospective cohort study among HIV-negative MSM in Urumqi of Xinjiang from 1 April 2016 to 14 July 2020. Participants were recruited through a local non-government organization using a website advertisement. Self-administered questionnaires and self-collected anal swabs were collected at baseline and every 6 months. The incidence rates of reinfection was calculated based on the number of events divided by person-months of observation of event risk. 95% confidence intervals (CIs) were calculated based on the Poisson distribution. Results A total of 515 HIV-negative unvaccinated MSM were included with a mean age of 30.93 years (SD 7.85), and 27.68% were reinfected with any 9v-HPV type after clearance. The reinfection incidence rate of any 9v-HPV was 14.47 per 1000 person-months (95% CI: 11.52–17.87). HPV52 was the most common type of reinfection, with a reinfection rate of 17.96 per 1,000 person months (95% CI: 11.58–26.33). Univariate analysis showed that MSM over the age of 30 had a slightly higher risk of reinfection with any 9v-HPV (Hazard ratio (HR): 1.57; 95% CI: 1.01–2.45), but no significant association was observed in multivariate analysis. Conclusions Our study showed MSM without HPV vaccine will become reinfected following the natural clearance of specific HPV types. It is also suggested that HPV vaccination is recommended not only prior to sexual debut but also after viral clearance for MSM to reduce HPV prevalence.

Incidence, Persistence, and Clearance of Anal Human Papillomavirus among Men Who Have Sex with Men in China: An Observational Cohort Study. Pathogens 2022; 11:pathogens11030314. [PMID: 35335637 PMCID: PMC8949987 DOI: 10.3390/pathogens11030314] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 02/24/2022] [Accepted: 03/01/2022] [Indexed: 02/07/2023] Open
Abstract
(1) Background: We conducted a prospective observational cohort study to measure incidence, persistence, and clearance of anal human papillomavirus (HPV) among men who have sex with men (MSM) in China. (2) Methods: MSM were recruited in Guangzhou, Shenzhen and Wuxi, China in 2017. A tablet-based questionnaire was used to collect sociodemographic and behavioral characteristics. An anal brush sample was collected for HPV testing and genotyping. Participants were followed up 12 months after enrolment. (3) Results: A total of 196 participants completed two HPV tests with a median age of 27.3 (interquartile range (IQR) 24.0–32.8) years. Rate of incidence, persistence, and clearance for HPV among MSM were 31.3 (95% confidence interval (CI) 24.7–39.2), 47.9 (36.8–61.3), and 122.5 (104.3–143.0) per 1000 person months (pm), respectively. HPV 16 (4.1/1000 pm) had the highest incidence rate, and HPV 6 (47.4/1000 pm) had the highest persistence rate. Having lower education and engaging in receptive anal intercourse were potential risk factors of HPV incidence. A higher incidence rate was observed among younger MSM. (4) Conclusions: The high incidence and low clearance of anal HPV highlight the necessity of HPV vaccination among MSM. Further studies are needed to clarify the HPV dynamics at multiple anatomical sites and the burden of HPV-related diseases among MSM.

High Human Papillomavirus Vaccine Acceptability and Cost-Effectiveness of the Chinese 2-Valent Vaccine Among Men Who Have Sex With Men: A Cross-Sectional Study in Shenyang, China. Front Med (Lausanne) 2021; 8:763564. [PMID: 34869470 PMCID: PMC8639684 DOI: 10.3389/fmed.2021.763564] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 10/28/2021] [Indexed: 12/15/2022] Open
Abstract
Background: Despite the insupportable burden caused by the human papillomavirus (HPV) and high vaccine acceptability, vaccination programs are not currently available for men who have sex with men (MSM). We aimed to assess HPV infection by examining the willingness for vaccination among MSM and cost-effectiveness of the Chinese 2-valent HPV vaccine. Methods: We recruited MSM in Shenyang, China between July and December 2020 to conduct anal HPV testing and an online survey regarding HPV-related knowledge and vaccine acceptability. We performed a cost-effectiveness analysis to evaluate the incremental cost-effectiveness ratios (ICERs) of the Chinese 2-valent HPV vaccine. Results: A total of 234 participants completed the online survey; of those, 203 were successfully tested for HPV. The median age was 30 years [interquartile range (IQR): 23-38 years]. Most participants had at least undergraduate education (136/234, 58.1%). The acceptability rate for the free HPV vaccine was 57.7% (135/234). The prevalence of HPV types 16 and 18 was 14.9% (18/121) and 26.8% (22/82) in the willing and unwilling to vaccinate groups, respectively (P > 0.05). The prevalence of high-risk HPV among participants aged <30 and ≥50 years was 48.6 and 38.9%, respectively. Using the Chinese per capita gross domestic product (GDP) as a threshold, the Chinese 2-valent HPV vaccine would be a "very cost-effective" strategy, with an ICER value of USD 4,411. This evidence showed that the Chinese 2-valent HPV vaccine was more cost-effective than other imported vaccines. Conclusions: Targeted strategies should be utilized in MSM with different rates of vaccine acceptability. A pilot HPV vaccination program based on the Chinese 2-valent HPV vaccine for MSM is urgently warranted to reduce the burden of HPV and anal cancer.

Abstract
BACKGROUND Reports of human papillomavirus (HPV) infection and genotype distribution in Chinese men are limited, and HPV vaccination has not yet been recommended for men in China. MATERIAL AND METHODS We retrospectively reviewed the prevalence and genotyping of male genital HPV. A total of 1227 male patients (aged 17 to 81 years) attending the dermatology and sexually transmitted disease clinics at Putuo District Center Hospital in Shanghai from 2015 to 2019 were included. Genital exfoliated specimens were obtained for detection and genotyping of 27 HPV types by Luminex-based multiplex assay. RESULTS The prevalence of any HPV was 65.5% (804/1227). The rate of multiple infection was 25.8% (317/1227). The 5 main HPV types were 6 (32.0%), 11 (23.2%), 16 (5.6%), 43 (4.3%), and 59 (4.0%). Among all detected HPV genotypes, 65.5% (875/1336) were 9-valent HPV genotypes. No significant differences were observed in the detection rate of HPV infection over 5 years (P>0.05). Age groups ≤24 years (70.7%) and ≥55 years (72.9%) showed higher infection rates, and significant differences were detected in rates of low-risk HPV infection in different age-stratified groups (P<0.05). Prevalence of HPV infection among patients with warts (74.4%) was significantly higher than that of patients with other clinical characteristics (40.4%) and physical examination (63.6%). CONCLUSIONS Our study suggested that more than half of Chinese male patients have detectable HPV infections, and penis-genital and anogenital warts were the most common clinical manifestations. Moreover, the available 9-valent HPV vaccine covers the most frequently observed HPV types among men.

Abstract
BACKGROUND Young men who have sex with men (YMSM) are particularly at increased risk for human papillomavirus (HPV) infection and related malignancies. Rectal douching, commonly practiced among MSM, has been associated with HIV, chlamydia, gonorrhea, and viral hepatitis in cross-sectional studies. We conducted this study to understand the association between self-reported rectal douching and anal HPV among YMSM in China. METHODS Between September 2018 and March 2019, MSM aged 15 to 24 years who ever engaged in receptive anal intercourse over the last 3 months were recruited via community-based organizations and centers for disease control located in 4 cities in China. Participants were asked to complete an online survey. We performed multivariate logistic regression adjusted for potential confounders to examine the association between self-reported rectal douching and anal HPV. RESULTS Among 273 MSM with a median age of 20 years (interquartile range, 19-21 years) included in this study, 130 (47.6%) practiced rectal douching during the preceding 3 months and 96 (36.2%) were infected with anal HPV. Self-reported rectal douching was found to be associated with increased odds of anal HPV infection (odds ratio, 2.16; 95% confidence interval, 1.22-3.82) among YMSM, after adjusting for age, sexual debut, sex with alcohol or drugs, and HIV testing history. CONCLUSIONS Self-reported rectal douching is associated with higher odds of anal HPV infection independent of sexual behaviors among YMSM. More prospective studies to ascertain this association are needed. Health education materials should inform men of the potential risk of rectal douching. Research on safer rectal douching procedures is warranted.

Abstract
INTRODUCTION As the leading sexually transmitted infection worldwide, human papillomavirus (HPV) may disproportionately affect transwomen. We aimed to estimate anal HPV prevalence, especially focusing on high-risk (hr)-HPV types and evaluate their associated factors among transwomen living in Rio de Janeiro, Brazil. METHODS Transwomen enrolled in a respondent-driven sampling (RDS)-based survey conducted between August 2015 and January 2016 self-collected anal samples, which were promptly stored at minus 80°C. After DNA extraction, HPV detection and genotyping were performed using the PapilloCheck test. We estimated HPV prevalences and evaluated the correlates of anal hr-HPV infection using a regression logistic model. RESULTS Out of 345 transwomen, 272 (78.8%) were included in this analysis (122 [44.9%] HIV-positive). No participant had ever received HPV vaccination. Among participants enrolled, 212 (77.9%) were positive for any anal HPV type and 165 (60.7%) for hr-HPV. Most common hr-HPV were as follows: HPV16 (17.6%), HPV68 (14.7%), HPV39 (14.3%), HPV56 (12.5%), HPV51 (11.4%) and HPV52 (11.0%). HIV-positive transwomen had three times the odds of having an hr-HPV compared to HIV-negative transwomen. Participants who had a current rectal Neisseria gonorrhoeae infection had 3.7 times the odds of being coinfected with hr-HPV. Among HIV-positive transwomen, neither antiretroviral therapy use, undetectable viral load, current and nadir CD4 counts were associated with anal hr-HPV infection. CONCLUSIONS Brazilian transwomen in our study exhibit some of the highest population-specific rates of HPV and hr-HPV. There is an urgent need to elucidate the burden of HPV infection, prevalence of HPV-related diseases and access to and uptake of HPV vaccination among transwomen, especially from low- and middle-income settings.

Abstract
Aim: Men who have sex with men (MSM) harbor a significant burden of human papillomavirus (HPV)-related diseases that could be prevented by vaccination. Materials & methods: Prevalence of HPVs targeted by the quadrivalent (4vHPV) and nonavalent vaccines (9vHPV) was assessed in anal (n = 443) and oral (n = 193) specimens of immunocompetent, sexually active MSM, using the Linear Array. Results: Of the anal samples, 34.1 and 46.0% were positive for at least one genotype of those covered by the 4vHPV and 9vHPV, respectively. At least one of the HPVs targeted by the 9vHPV was detected in 5.7% of the oral specimens. Conclusion: The majority of the subjects were not currently infected by HPV-16 and other vaccine-preventable HPVs. Universal HPV vaccination should be strongly promoted in order to achieve protection for all risk groups. In the meanwhile, vaccination should be offered to sexually active adult MSM attendees of sexually transmitted infection centers, although its potential benefit for these subjects needs to be further investigated.

Abstract
Men who have sex with men (MSM) attending university are a high-risk population for human papillomavirus (HPV) infection and are a neglected population of HPV vaccination programs in China. To provide evidence for HPV vaccination policies, we conducted this study to examine the prevalence and factors associated with anal HPV infection among MSM attending university in China. A self-administered online questionnaire was conducted to collect information on social demographics and sexual behaviors. A self-collected rectal swab specimen was collected to test for 37 HPV types. A total of 426 participants were tested for HPV. The median age was 20 years. HPV prevalence was 37.5% for any type, 29.8% for nine-valent vaccine types, 24.6% for four-valent vaccine types, 11.5% for HPV-16/18, and 15.7% for HPV-6/11. Men enrolled in a technical diploma, living in Northern China, having more than two sex partners, being bottom or versatile in anal sex, and having a human immunodeficiency virus (HIV) testing history were more likely to have positive anal HPV of any type. Our study found a high prevalence of anal HPV infection among MSM attending university in China, with HPV vaccine-preventable types being the most popular types in this group. Thus, our findings highlight the urgency of promoting HPV vaccination among teenage MSM.
