Abstract
The number of people living with HIV infection has been increasing globally. Administration of antiretroviral therapy is effective in controlling the infection for most patients and, as a consequence, people living with HIV (PLWH) now often have a long life expectancy. However, their risk of developing cancer - most notably virus-related cancers - has been increasing. To date, few studies have assessed the risk of genitourinary cancers in PLWH, and robust scientific data on their treatment-related outcomes are lacking. Previous studies have noted that PLWH are at a reduced risk of prostate cancer; however, low adoption and/or availability of prostate cancer screening among these patients might be confounding the validity of this finding. In genitourinary cancers, advanced stage at diagnosis and reduced cancer-specific mortality have been reported in PLWH. These data likely reflect, at least in part, the inequity of health care access for PLWH. Notably, systemic chemotherapy and/or radiotherapy could decrease total CD4+ cell counts, which could, therefore, increase the risk of morbidity and mortality from cancer treatments in PLWH. Immune checkpoint inhibitors have become the therapeutic backbone for many advanced malignancies in the general population; however, most studies validating their efficacy have excluded PLWH owing to concerns of severe adverse effects from immune checkpoint inhibitors themselves and/or related to their immunosuppressed status. To our knowledge, no genitourinary cancer survivorship programme exists that specifically caters to the needs of PLWH. By including PLWH in ongoing cancer trials, we can gain invaluable insights that will help to improve cancer care specifically for PLWH.

Abstract
OBJECTIVES This study aims to estimate the incidence and persistence/clearance of anal human papilloma virus (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 [adjusted hazard ratio (aHR) = 0.44, 95% confidence interval (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 g 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. CONCLUSION 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.

Abstract
BACKGROUND Real-world evidence of human papillomavirus (HPV) vaccine effectiveness (VE) against longitudinal outcomes is lacking among gay, bisexual, and other men who have sex with men (GBM). We compared 12-month incidence and persistence of anal HPV infection between vaccinated and unvaccinated GBM. METHODS We recruited GBM aged 16-30 years in Montreal, Toronto, and Vancouver, Canada, from 2017 to 2019. Participants were followed over a median of 12 months (interquartile range, 12-13 months). Participants self-reported HPV vaccination and self-collected anal specimens for HPV DNA testing. We calculated prevalence ratios (PR) for 12-month cumulative incidence and persistence with ≥1 quadrivalent vaccine type (HPV 6/11/16/18) between vaccinated (≥1 dose at baseline) and unvaccinated participants using a propensity score-weighted, modified Poisson regression. RESULTS Among 248 participants, 109 (44.0%) were vaccinated at baseline, of whom 62.6% received 3 doses. PRs for HPV 6/11/16/18 were 0.56 (95% confidence interval [CI], .24-1.31) for cumulative incidence and 0.53 (95% CI, .25-1.14) for persistence. PRs were 0.23 (95% CI, .05-1.03) and 0.08 (95% CI, .01-.59) for incidence and persistence, respectively, among participants who received their first dose at age ≤23 years and 0.15 (95% CI, .03-.68) and 0.12 (95% CI, .03-.54) among participants who were sexually active for ≤5 years before vaccination. CONCLUSIONS Findings support national recommendations for HPV vaccination at younger ages or soon after sexual debut.

Abstract
BACKGROUND Understanding the natural history of anal high-risk human papillomavirus (hrHPV) infection is key for designing anal cancer prevention programs but has not been systematically characterized. METHODS We reanalyzed data from 34 studies including 16 164 individuals in 6 risk groups defined by human immunodeficiency virus (HIV) status, sex, and male sexuality: men who have sex with men (MSM) and people with HIV (MSMWH), HIV-negative MSM, women with HIV (WWH), HIV-negative women, men who have sex with women (MSW) with HIV (MSWWH), and HIV-negative MSW. We used Markov models to estimate incidence and clearance of 13 hrHPV types and their determinants. RESULTS Human papillomavirus (HPV) 16 had the highest incidence-clearance ratio of the hrHPV types. MSMWH had the highest hrHPV incidence (eg, 15.5% newly HPV-16 infected within 2 years), followed by HIV-negative MSM (7.5%), WWH (6.6%), HIV-negative women (2.9%), MSWWH (1.7%), and HIV-negative MSW (0.7%). Determinants of HPV-16 incidence included HIV status and number of sexual partners for MSM, women, and MSW, and anal sex behavior for MSM only. HPV-16 clearance was lower for people with HIV (PWH) and lower for prevalent than incident infection. Among MSM, increasing age was associated with lower clearance of prevalent, but not incident, HPV-16 infection. CONCLUSIONS This robust and unifying analysis of anal hrHPV natural history is essential to designing and predicting the impact of HPV vaccination and HPV-based screening programs on anal cancer prevention, particularly in MSM and PWH. Importantly, it demonstrates the higher carcinogenic potential of longstanding anal prevalent hrHPV infection than more recent incident infection.

Abstract
INTRODUCTION Approaches to estimating clearance rates, an important metric of human papillomavirus (HPV) clearance, for HPV groupings differ between studies. We aimed to identify the approaches used in the literature for estimating grouped HPV clearance rates. We investigated whether these approaches resulted in different estimations, using data from existing studies. METHODS In this systematic review, we included articles that reported clearance rates of HPV groupings. We identified approaches to data in the HAVANA cohort, comprising adolescent girls, and the H2M cohort, comprising men who have sex with men. We estimated clearance rates for six HPV groupings (bivalent-, quadrivalent- and nonavalent vaccine-related, and low-risk, high-risk, and any HPV). RESULTS From 26 articles, we identified 54 theoretically possible approaches to estimating clearance rates. These approaches varied regarding definitions of clearance events and person-time, and prevalence or incidence of infections included in the analysis. Applying the nine most-used approaches to the HAVANA ( n = 1,394) and H2M ( n = 745) cohorts demonstrated strong variation in clearance rate estimates depending on the approach used. For example, for grouped high-risk HPV in the H2M cohort, clearance rates ranged from 52.4 to 120.0 clearances/1000 person-months. Clearance rates also varied in the HAVANA cohort, but differences were less pronounced, ranging from 24.1 to 57.7 clearances/1000 person-months. CONCLUSIONS Varied approaches from the literature for estimating clearance rates of HPV groupings yielded different clearance rate estimates in our data examples. Estimates also varied between study populations. We advise clear reporting of methodology and urge caution in comparing clearance rates between studies.

Abstract
OBJECTIVES Young sexual minority men (SMM) exhibit a high prevalence and incidence of high-risk genotypes of human papillomavirus (hrHPV) anal infections and a confluence of a high prevalence of HIV and rectal STIs. Social determinants of health (SDOHs) are linked to social network contexts that generate and maintain racial disparities in HIV and STIs. A network perspective was provided to advance our knowledge of drivers of genotype-specific hrHPV infection and coinfection with HIV. The study also examined whether socially connected men are infected with the same high-risk HPV genotypes and, if so, whether this tendency is conditioned on coinfection with HIV. METHODS Our sample included 136 young SMM of predominantly black race and their network members of other races and ethnicities, aged 18-29 years, who resided in Houston, Texas, USA. These participants were recruited during 2014-2016 at the baseline recruitment period by network-based peer referral, where anal exfoliated cells and named social and sexual partners were collected. Exponential random graph models were estimated to assess similarity in genotype-specific hrHPV anal infection in social connections and coinfection with HIV in consideration of the effects of similarity in sociodemographic, sexual behavioural characteristics, SDOHs and syphilis infection. RESULTS Pairs of men socially connected to each other tend to be infected with the same hrHPV genotypes of HPV-16, HPV-45 and HPV-51 or HPV-16 and/or HPV-18. The tendency of social connections between pairs of men who were infected with either HPV-16 or HPV-18 were conditioned on HIV infection. CONCLUSIONS Networked patterns of hrHPV infection could be amenable to network-based HPV prevention interventions that engage young SMM of predominantly racial minority groups who are out of HIV care and vulnerable to high-risk HPV acquisition.

Abstract
Cisgender sexual minority men (SMM) and transgender women are disproportionately vulnerable to HPV-related anal cancer, but little is known about longitudinal predictors of high-risk human papillomavirus (hrHPV) infection in this population. As such, this analysis aims to identify factors associated with incident anal hrHPV infection in a diverse cohort of young SMM and transgender women. This study of HPV infection, nested within a larger cohort study, took place between October 2015 and January 2020. Participants completed a brief computer survey assessing HPV symptomatology, risk, and prevention alongside multi-site testing, in addition to biannual cohort study assessments. In the analytic sample of 137 participants, 31.6% tested positive for an anal hrHPV infection, with 27.0% and 29.9% testing positive for incident anal hrHPV infections at Visits 2 and 3, respectively. When adjusting for time between study visits, participants had significantly greater odds of incident anal hrHPV at Visit 2 if they had a concurrent HSV infection (AOR = 5.08 [1.43, 18.00]). At Visit 3, participants had significantly greater odds of incident anal hrHPV infection if they reported a greater number of sex partners in the previous month (AOR = 1.25 [1.03, 1.51]). Prevalence of cancer-causing HPV at baseline was high and many participants tested positive for additional types of anal hrHPV at subsequent visits. Risk for newly detected anal hrHPV infection was significantly associated with biological and behavioral factors. Our findings strongly indicate a need for programs to increase uptake of HPV vaccination and provide HPV-related health education for sexual and gender minorities.

Update on the Epidemiological Features and Clinical Implications of Human Papillomavirus Infection (HPV) and Human Immunodeficiency Virus (HIV) Coinfection. Microorganisms 2022; 10:microorganisms10051047. [PMID: 35630489 PMCID: PMC9147826 DOI: 10.3390/microorganisms10051047] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/12/2022] [Accepted: 05/17/2022] [Indexed: 12/01/2022] Open
Abstract
Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. Although most HPV infections will spontaneously resolve, a considerable proportion of them will persist, increasing the risk of anogenital dysplasia, especially within certain populations, such as patients infected with human immunodeficiency virus (HIV). Furthermore, high-risk oncogenic HPV types (HR-HPV) are the main cause of cervix and other anogenital cancers, such as cancer of the vagina, vulva, penis, or anus. HIV and HPV coinfection is common among people living with HIV (PLWH) but disproportionally affects men who have sex with men (MSM) for whom the rate of persistent HPV infection and reinfection is noteworthy. The molecular interactions between HIV and HPV, as well as the interplay between both viruses and the immune system, are increasingly being understood. The immune dysfunction induced by HIV infection impairs the rate of HPV clearance and increases its oncogenic risk. Despite the availability of effective antiretroviral therapy (ART), the incidence of several HPV-related cancers is higher in PLWH, and the burden of persistent HPV-related disease has become a significant concern in an aging HIV population. Several public health strategies have been developed to reduce the transmission of HIV and HPV and mitigate the consequences of this type of coinfection. Universal HPV vaccination is the most effective preventive tool to reduce the incidence of HPV disease. In addition, screening programs for HPV-related cervical and vulvovaginal diseases in women are well-recognized strategies to prevent cervical cancer. Similarly, anal dysplasia screening programs are being implemented worldwide for the prevention of anal cancer among PLWH. Herein, the main epidemiological features and clinical implications of HIV and HPV coinfection are reviewed, focusing mainly on the relationship between HIV immune status and HPV-related diseases and the current strategies used to reduce the burden of HPV-related disease.

Abstract
Objective Men who have sex with men (MSM) are at increased risk for Human papillomavirus (HPV) infection compared to women and heterosexual men. We aimed to assess the incidence, clearance and duration of anal human papillomavirus (HPV) infection in HIV-negative MSM and the influencing factors in a 5-year prospective cohort study. Methods From April 2016 to April 2021, HIV-negative MSM were recruited and followed every 6 months in Urumqi, Xinjiang, China. Questionnaires and anal swabs were collected at baseline and every 6 months. We detected 37 anal HPV genotypes using the HPV Geno Array Diagnostic Kit Test. Incidence and clearance rates of anal HPV infection and the influencing factors were estimated using a two-state Markov model. Results A total of 585 MSM were included with a median age of 37 years [interquartile range (IQR): 31–43 years] and were followed for a median 2.8 years (IQR: 1.8–3.6 years). Incidence rates for any HPV and high-risk HPV (Hr-HPV) were 53.4 [95% confidence interval (CI): 49.1–58.0] and 39.0 (95% CI: 35.7–42.5)/1,000 person-months. Median duration of infection was 9.67 (95% CI: 8.67–10.86) and 8.51 (95% CI: 7.57–9.50) months, respectively. Clearance rates for any HPV and Hr-HPV were 50.9 (95% CI: 46.7–55.3) and 62.1 (95% CI: 56.8–66.7)/1,000 person-months, respectively. HPV16 and HPV6 had the highest incidence, lowest clearance rate and longest duration of infection among Hr-HPV and low-risk HPV (Lr-HPV) types, respectively. Receptive anal sex is a risk factor for any HPV [hazard ratio (HR) = 1.66, 95% CI: 1.16–2.38] and Hr-HPV infection (HR = 1.99, 95% CI:1.39–2.85). Recent anal sex without condom use was significantly associated with any HPV (HR = 1.80, 95% CI: 1.10–2.94) and Hr-HPV infection (HR = 2.60, 95% CI: 1.42–4.77). Age ≥35 years was significantly associated with Lr-HPV HPV infection only (HR = 1.40, 95% CI: 1.02–1.93). Both inserted and receptive anal sex (HR = 0.60, 95% CI: 0.40–0.89) and anal sex ≥2 times per week (HR = 0.61, 95% CI: 0.43–0.87) were associated with reduced Hr-HPV clearance. Six of the nine-valent vaccine types (HPV6, 11, 16, 18, 52 and 58) occurred most frequently, which indicates the need for high vaccination coverage in MSM. Conclusions In this cohort study, high incidence and low clearance of any HPV, Hr-HPV and individual HPV infections emphasize the importance of MSM vaccination. Modifiable behavioral factors such as condoms and drug use should be incorporated into HPV prevention strategies.

Abstract
BACKGROUND Multiple anal human papillomavirus (HPVs) may increase the risk of anal cancer among men who have sex with men (MSM) living with human immunodeficiency virus (HIV). The Jaccard Similarity Index (JSI) was explored as a measure of multiple HPV persistence. METHODS The TRUST/RV368 cohort enrolled MSM living with and without HIV in Abuja and Lagos, Nigeria. Participants with anal swabs at baseline, 3- and 12-month visits were tested for high- and low-risk HPVs using a next-generation sequencing assay. Persistence of the same HPV genotypes over time was calculated using the JSI and categorized into high, medium, and low similarity tertiles. Factors associated with higher versus lower similarity were estimated with multivariable ordinal logistic regression and reported as adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS Of the 225 participants, median age was 25 years (interquartile range, 22-29 years), 62% were living with HIV, median HPVs was 3 (interquartile range, 2-5), and HPV6 (28%), HPV16 (26%), HPV11 (23%), and HPV45 (20%) were most prevalent. Fifty-three percent of participants had highly similar HPVs at 3 months, and the similarity was associated with HIV (aOR, 3.11; 95% CI, 1.6-5.9) and recent receptive sex (aOR, 1.9; 95% CI, 1.0-3.5). By 12 months, 20% had highly similar HPVs, and it was associated with 12 years or longer since anal coital debut (aOR, 6.8; 95% CI, 3.1-5.2), self-reported genital warts (aOR, 3.1; 95% CI, 1.5-6.6), and 200 or less CD4 cells/mm3 (aOR, 13.3; 95% CI, 2.7-65.2) for those living with HIV. CONCLUSIONS Studies evaluating the JSI as a predictor of high-grade intraepithelial lesions would further confirm its applicability as a quantitative measure of multiple HPV persistence.

Abstract
Objectives This study aims to investigate the association between CD4+ T cell count and combined antiretroviral therapy (cART) with the prevalence of anal human papillomavirus (HPV) infection among HIV-positive male cohort in China. Methods A survey was conducted in men from a HIV cohort in Taizhou, China between 2016 and 2019. A face-to-face questionnaire interview was administered, and an anal-canal swab was collected for HPV genotyping. Results A total of 766 HIV-positive men were recruited. The HPV prevalence was lower among those with increased CD4+ T cell count than those with decreased or unchanged (46.5 vs. 56.6%, p = 0.033) from baseline. In multivariable models, having the current CD4+ T cell count of 350–499 cells/µL (aOR 0.28, 95% CI 0.13–0.64), and of ≥ 500 cells/µL (aOR 0.26, 95% CI 0.11–0.60) were associated with lower prevalence of any type HPV infection compared with those with < 200 cells/µL. Having taken NVP + 3TC + AZT was inversely associated with any high-risk (HR)-HPV (aOR 0.47, 95% CI 0.25–0.90) and any low-risk (LR)-HPV infection (aOR 0.40, 95% CI 0.18–0.88), compared with those taking EFV + 3TC + TDF. Conclusions Increased CD4+ T cell count at follow-up was significantly associated with lower prevalence of anal HPV infection. Inverse associations between NVP + 3TC + AZT and HR-HPV or LR-HPV infecton were observed.

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.

Abstract
BACKGROUND Starting in 2015, human papillomavirus (HPV) vaccine has been publicly funded for gay, bisexual, and other men who have sex with men (GBM) 26 years or younger in Canada. METHODS Self-identified GBM who reported having sex with another man within the past 6 months were enrolled using respondent-driven sampling (RDS) between February 2017 and August 2019 in Montreal, Toronto, and Vancouver, Canada. Men aged 16 to 30 years self-collected anal specimens for HPV-DNA testing. Prevalence was estimated using RDS-II weights. We compared the prevalence of quadrivalent (HPV-6/11/16/18) and 9-valent (HPV-6/11/16/18/31/33/45/52/58) vaccine types between GBM who self-reported HPV vaccination (≥1 dose) and those reporting no vaccination using a modified Poisson regression for binary outcomes. RESULTS Among 645 GBM who provided a valid anal specimen (median age, 26 years; 5.9% HIV positive), 40.3% reported receiving ≥1 dose of HPV vaccine, of whom 61.8% received 3 doses. One-quarter were infected with ≥1 quadrivalent type (crude, 25.7%; RDS weighted, 24.4%). After adjustment for potential confounders, vaccinated GBM had a 27% lower anal prevalence of quadrivalent types compared with unvaccinated GBM (adjusted prevalence ratio [aPR], 0.73; 95% confidence interval [CI], 0.54-1.00). Lower prevalence ratios were found among vaccinated participants who were vaccinated >2 years before enrollment (aPR, 0.47; 95% CI, 0.25-0.86) or received their first vaccine dose at age ≤23 years (aPR, 0.64; 95% CI, 0.42-0.99). Point estimates were similar for ≥2 or 3 doses and 9-valent types. CONCLUSIONS Human papillomavirus vaccination was associated with a lower anal prevalence of vaccine-preventable HPV types among young, sexually active GBM. Findings will help inform shared decision making around HPV vaccination for GBM and their healthcare providers.

Abstract
HIV-infected men who have sex with men (MSM) display the highest prevalence of anal infection by high-risk Human Papillomaviruses (hrHPVs) and incidence of anal carcinoma. Anal specimens were genotyped by the Linear Array. Incidence and clearance of anal infection by hrHPVs, hrHPVs other than HPV16, low-risk HPVs, and four individual types (6,11,16,18) were estimated using a two-state Markov model. Determinants for incidence and clearance were assessed by logistic regression. Overall, 204 individuals were included (median age 42 years, IQR = 34-49). For hrHPVs, incidence and clearance rates were 36.1 × 1000 person-months (p-m) (95% CI 23.3-56.5) and 15.6 × 1000 p-m (95% CI 10.7-23.3), respectively. HPV16 showed a higher incidence than HPV18 (10.2 vs. 7.2 × 1000 p-m). Its clearance was more than twofold lower than that of HPV18 (30.1 vs. 78.2 × 1000 p-m). MSM receiving cART displayed a 68% to 88% decrease in risk of acquiring hrHPVs, hrHPVs other than HPV16, HPV16, and HPV18 (adjusted Hazard Ratio [aHR] 0.13, 95% CI 0.02-0.67; aHR 0.22, 95% CI 0.06-0.78; aHR 0.32, 95% CI 0.12-0.90; aHR 0.12, 95% CI 0.04-0.31, respectively) than patients not treated. A nadir CD4 + count < 200 cells/mm3 significantly reduced the clearance of hrHPVs other than HPV16 (aHR 0.39, 95% CI 0.17-0.90). cART use reduces the risk of acquiring anal infection by hrHPVs.

Abstract
BACKGROUND Men who have sex with men (MSM) are at increased risk of anogenital human papillomavirus (HPV) infections. We aimed to assess the incidence and clearance of penile high-risk HPV (hrHPV) infections and their determinants among HIV-negative MSM living in the Netherlands. METHODS Between 2010 and 2015, HIV-negative MSM were semiannually tested for penile HPV and completed detailed questionnaires on health and sexual behavior. Self-collected penile swabs were tested for HPV DNA using SPF10-PCR DEIA/LiPA25 system. Type-specific hrHPV incidence (IR) and clearance rates (CR) were calculated for 12 hrHPV types (HPV-16, HPV-18, HPV-31, HPV-33, HPV-35, HPV-39, HPV-45, HPV-51, HPV-52, HPV-56, HPV-58, and HPV-59). Determinants of incidence and clearance of HPV-16 and HPV-18, separately, and combined 7 hrHPV types covered by the nonavalent vaccine were assessed by Poisson regression using generalized estimating equations for combined hrHPV types. RESULTS We included 638 HIV-negative MSM, with a median age of 38 (interquartile range, 33-43) years. HPV-16 had an IR of 4.9/1000 person-months of observation at risk (PMO; 95% confidence interval [95% CI], 3.8-6.3) and CR of 90.6/1000 PMO (95% CI, 60.7-135.1). The IR and CR of HPV-18 were 3.4/1000 PMO (95% CI, 2.5-4.5) and 119.2/1000 PMO (95% CI, 76.9-184.8), respectively. Age and condom use during insertive anal sex were not associated with hrHPV incidence, whereas high number of recent sex partners was. CONCLUSIONS The relatively high IR and low CR of penile HPV-16 and HPV-18 among HIV-negative MSM correlates with their high prevalence and oncogenic potential. Incident HPV infections were associated with recent sexual risk behavior.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is more frequent in men having sex with men (MSM) who are living with human immunodeficiency virus (HIV) than in MSM without HIV. There are currently no data regarding HPV infections in preexposure prophylaxis (PrEP)-using MSM. METHODS MSM living without HIV who were enrolled in the Agence Nationale de Recherches sur le SIDA et les Hépatites Virales "Intervention Préventive de l'Exposition aux Risques avec et pour les hommes Gays" PrEP study were prospectively enrolled. Anal, penile, and oral samples were collected at baseline and every 6 months for HPV detection and genotyping. Anal swabs for cytology were obtained at baseline and at 24 months. RESULTS We enrolled 162 participants. The prevalences of any HPV genotypes at baseline were 92%, 32%, and 12% at the anal, penile, and oral sites, respectively. High-risk (HR) HPV genotypes were observed in 84%, 25%, and 10% of anal, penile, and oral baseline samples, respectively. Nonavalent HPV vaccine genotypes were observed in 77%, 22%, and 6% of anal, penile, and oral baseline samples, respectively. Multiple infections were observed in 76%, 17%, and 3% of cases at the anal, penile, and oral sites, respectively. The most frequent HR genotypes were HPV 53, 51, and 16 in anal samples; HPV 33, 39, and 73 in penile samples; and HPV 66 in oral samples. The incidence of any HPV genotype at the anal site was 86.2/1000 person-months and the incidence of HR-HPV genotypes was 72.3/1000 person-months. The baseline cytology was normal in 32% of cases and was classified as atypical squamous cells of undetermined significance, low-grade squamous intra-epithelial lesion, high-grade squamous intra-epithelial lesion (HSIL), and atypical squamous cells that cannot exclude HSIL in 23%, 40%, 5%, and 1% of cases, respectively. CONCLUSIONS PrEP users have a similar risk of HPV infection as MSM living with HIV and the risk is much higher than that previously reported in MSM living without HIV.

Abstract
Objective High-risk human papillomavirus (HRHPV) causes anal cancer, which disproportionately affects gay and bisexual men (GBM). We examined sexual behaviours associated with incident anal HRHPV in an observational cohort study of GBM in Sydney, Australia. Methods GBM aged 35 years and above were enrolled in the Study of the Prevention of Anal Cancer. Detailed information on sexual practices in the last 6 months, including receptive anal intercourse (RAI) and non-intercourse receptive anal practices, was collected. Anal human papillomavirus (HPV) testing was performed at the baseline and three annual follow-up visits. Risk factors for incident HRHPV were determined by Cox regression using the Wei-Lin-Weissfeld method. Results Between 2010 and 2015, 617 men were recruited and 525 who had valid HPV results at baseline and at least one follow-up visit were included in the analysis. The median age was 49 years (IQR 43–56) and 188 (35.8%) were HIV-positive. On univariable analysis, incident anal HRHPV was associated with being HIV-positive (p<0.001), having a higher number of recent RAI partners regardless of condom use (p<0.001 for both), preference for the receptive position during anal intercourse (p=0.014) and other non-intercourse receptive anal sexual practices, including rimming, fingering and receptive use of sex toys (p<0.05 for all). In multivariable analyses, being HIV-positive (HR 1.46, 95% CI 1.09 to 1.85, p=0.009) and reporting condom-protected RAI with a higher number of sexual partners (p<0.001) remained significantly associated with incident HRHPV. When stratified by recent RAI, non-intercourse receptive anal practices were not associated with incident HRHPV in men who reported no recent RAI. Conclusion GBM living with HIV and those who reported RAI were at increased of incident anal HRHPV. Given the substantial risk of anal cancer and the difficulty in mitigating the risk of acquiring anal HRHPV, HPV vaccination should be considered among sexually active older GBM.

Abstract
BACKGROUND Incidence of anal cancer is highest in gay and bisexual men (GBM). Better understanding of the natural history of anal high-risk human papillomavirus (hrHPV) infection is needed for anal cancer prevention. METHODS The Study of the Prevention of Anal Cancer was a 3-year study of Australian GBM, aged 35 years or older. We examined incidence, clearance, and risk factors for 13 hrHPV types at baseline and 3 annual visits. RESULTS In 525 men with ≥ 2 visits, 348 (66.3%) acquired ≥ 1 incident hrHPV infection. HPV16 incidence rates were similar, but non-16 hrHPV incidence was higher in HIV-positive (51.8/100 person years [PY]) than HIV-negative men (36.5/100 PY, P < .001). Annual clearance rates of HPV16 (13.21/100 PY, 95% confidence interval, 10.53-16.56) were lower than for other hrHPV types. hrHPV clearance rates were not associated with HIV overall but were significantly lower in those with a lower nadir CD4 (<200 cells/µL) for HPV16 (P = .015) and other hrHPV types (P = .007). CONCLUSIONS Higher incidence of non-16 hrHPV types, coupled with lower clearance of non-16 hrHPV types in those with past impaired immune function, is consistent with the greater role of non-16 hrHPV in anal cancer in HIV-positive people.

Abstract
Objective. To classify the infection risk of human papillomavirus (HPV) among human immunodeficiency virus- (HIV-) negative men who have sex with men (MSM) using group-based trajectory modeling (GBTM). Methods. This study collected data on demographic and sexual behavior characteristics by questionnaires at semiannual visits from March 1st, 2016 to December 31th, 2017. Researchers collected anal exfoliated cells to finish HPV testing and blood samples to finish HIV testing at baseline and follow-up visits. Accumulative infection numbers of different types of HPV as the primary outcome and the follow-up visits as the independent predicator to build a GBTM model. Results. There were 500 potentially eligible HIV-negative participants at baseline, 361 (72.2%) of whom were included in this study after screening. Three trajectory groups were identified as the best-fitted GBTM model. Trajectory 1, defined as decreased group (DG) accounted for 44.6% (161/361) of the sample, showed a declining pattern with visits. Trajectory 2, defined as flat group (FG) accounted for 49.6% (179/361) of the sample, showed a flat pattern with visits. Trajectory 3, regarded as the increased group (IG) accounted for 5.8% (21/361) of the sample, showed an uptrend. Compared to the DG, risk factors for the FG included receptive anal intercourse (AOR, 2.24; 95% CI, 1.36-3.71), occasional condom use in anal sex during the past six months (AOR, 1.90; 95% CI, 1.16-3.14), experience of transactional sex with males in the past year (AOR, 3.60; 95% CI, 1.12-11.54), and substance use (AOR, 1.81; 95% CI, 1.08-3.04). Risk factors for the IG included receptive anal intercourse (AOR, 2.81; 95% CI, 1.04-7.70), occasional condom use in anal sex during the past six months (AOR, 3.93; 95% CI, 1.40-11.01), and history of other STIs (AOR, 5.72; 95% CI, 1.40-23.46). Conclusion. The MSM data in this study showed three distinct developmental trajectories (DG, FG, and IG) of HPV infection among HIV-negative MSM, with receptive anal intercourse and occasional condom use in anal sex during the past six months being the risk factors associated with FG and IG.

Abstract
OBJECTIVES Persistent anal high-risk human papillomavirus (HR-HPV) infection is a major risk factor for anal cancer among MSM and transgender women (TGW). We aimed to estimate incidence, clearance, and persistence of anal HR-HPV in HIV-positive and HIV-negative MSM and TGW, and to assess factors for HR-HPV persistence. DESIGN Prospective cohort study. METHODS MSM and TGW aged at least 18 years, were enrolled from Indonesia, Malaysia, and Thailand, then followed up 6-monthly for 12 months. Anal swabs were collected at every visit for HR-HPV genotypes to define anal HR-HPV incidence, clearance, and persistence. Logistic regression was used to evaluate factors associated with HR-HPV persistence. RESULTS Three hundred and twenty-five MSM and TGW were included in this study, of whom 72.3% were HIV-positive. The incidence of anal HR-HPV persistence was higher in HIV-positive than HIV-negative MSM participants (28.4/1000 vs. 13.9/1000 person-months). HIV-positive participants had HR-HPV lower clearance rate than HIV-negative participants (OR 0.3; 95% CI 0.1-0.7). The overall persistence of HR-HPV was 39.9% in HIV-positive and 22.8% HIV-negative participants. HPV-16 was the most persistent HR-HPV in both HIV-positive and HIV-negative participants. HIV infection (aOR 2.87; 95% CI 1.47-5.61), living in Kuala Lumpur (aOR 4.99; 95% CI 2.22-11.19) and Bali (aOR 3.39; 95% CI 1.07-10.75), being employed/freelance (aOR 3.99; 95% CI 1.48-10.77), and not being circumcised (aOR 2.29; 95% CI 1.07-4.88) were independently associated with anal HR-HPV persistence. CONCLUSION HIV-positive MSM and TGW had higher risk of persistent anal HR-HPV infection. Prevention program should be made available and prioritized for HIV-positive MSM and TGW where resources are limited.

Abstract
The treatment of condyloma is generally a challenge in clinical practice. Although the spontaneous resolution rate is high, a significant proportion of patients seek treatment, not because of symptomatology, but mainly for aesthetic issues and concerns related to the transmission or worsening of existing lesions. The available treatments should be applied only for clinically evident macroscopic lesions. Ideally, available therapies should have rapid action onset and clearance, resolve symptoms, reduce recurrence rate and viral load, be effective in treating small lesions, and be well tolerated. However, none of the currently available treatments is clearly more effective than the others and there is no ideal treatment for all patients or for all condyloma. Therefore, the therapeutic decision should be based on the clinician's experience, available resources, lesion morphology, size, number and location, primary or recurrent lesions, disease severity, patient preference and expectations, patient's immune competence, convenience, tolerance, cost of treatment and results of previous therapies. The available treatments are divided into three groups: applied by the patient himself (imiquimod 3.75 or 5%, podophyllotoxin .5%, synecatekines 10% or 15%), applied by the health care provider (bi- and tricloacetic acids 80%-90%, intralesional interferon alpha, cryotherapy, surgical removal, electrofulguration, laser ablation) and experimental or alternative therapies (topical cidofovir, intralesional bleomycin, photodynamic therapy). Treatment methodologies can be further divided into their action - ablative or destructive treatment (cryotherapy, electrofulguration, laser ablation, surgical excision), cytotoxic or proapoptotic treatments (podophyllotoxin .5%, 5-fluoruracil, bleomycin) and immunomodulatory treatments (imiquimod 3.75% or 5%, synecatekines 10% or 15%, intralesional interferon alpha). The overall success rate of the various treatments available ranges from 23% to 94%. Only treatments that include cryotherapy or surgical excision are suitable in condyloma with any anatomical location and that have the highest success rate in monotherapy. Recurrences are common regardless of the treatment received. In contrast, immunomodulatory therapies despite having lower initial clearance rates appear to have higher probabilities of cure in the medium term, with low recurrence rates. Some treatments may be combined with each other and the effectiveness of combined therapies appears to be superior to monotherapy (proactive sequential treatment). The consensuses for the treatment of HPV also consider special situations: immunocompromised patients, meatus and intraurethral lesions and treatment of the partner.

Incidence and Clearance of Anal High-risk Human Papillomavirus Infections and Their Determinants Over 5 Years Among Human Immunodeficiency Virus-negative Men Who Have Sex With Men. Clin Infect Dis 2020; 68:1556-1565. [PMID: 30169621 DOI: 10.1093/cid/ciy738] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2018] [Accepted: 08/29/2018] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND We aimed to assess the incidence and clearance of anal high-risk human papillomavirus (hrHPV) infections and determinants thereof among human immunodeficiency virus (HIV)-negative men who have sex with men (MSM) over a period of up to 5 years. METHODS From 2010 to 2015, HIV-negative MSM were followed every 6 months. Anal self-swabs were collected at inclusion and every 6 months thereafter, and were HPV genotyped using the SPF10-PCR DEIA/LiPA25-system-v1. Incidence rates (IRs) and clearance rates (CRs) of incident anal hrHPV infections were assessed by hrHPV type (types 16, 18, 31, 33, 45, 52, and 58). Determinants of transitions between uninfected and infected states were assessed by hrHPV type using a time-homogenous multi-state Markov model. RESULTS This study included 713 HIV-negative MSM, with a median age of 37 years (interquartile range [IQR] 31-43) and a median number of study visits of 6 (IQR 2-7). The IRs of anal infections had a median of 5.2 per 100 person-years (range: 2.2-7.9) across types, with HPV16 having the highest IR. The CRs of incident anal hrHPV infections had a median of 53.7 per 100 person-years (range: 33.4-65.3) across types, with HPV16 having the lowest CR. Having had over 100 lifetime sex partners was significantly associated with incident anal hrHPV infections in multivariable analyses. CONCLUSIONS The high incidence and low clearance rates of anal HPV16 infection, compared to other hrHPV types, is consistent with HPV16 being implicated in the large majority of anal cancer cases.

Abstract
BACKGROUND Men who have sex with men living with human immunodeficiency virus have a high risk of anal cancer. We estimate the likely benefit of human papillomavirus (HPV) vaccination among participants of the Anal Cancer Examination study. METHODS Anal swabs were collected for the detection and genotyping of anal HPV DNA by linear array (Roche Diagnostics) in this 2-year multicenter prospective cohort. We calculated the proportion of men, stratified by age, without detectable vaccine type-specific DNA. RESULTS Overall, 255 men, with a median age of 50 years (interquartile range, 44-56 years) contributed 488.9 person-years of follow-up. After 2 years of follow-up, 149 (58%; 95% confidence interval [CI], 52-65) had at least 1 high-risk HPV (HRHPV), and 71 (28%, 95% CI, 22-34) had HPV types 16/18 detected. Assuming that DNA-negative men would receive vaccine protection, vaccination at baseline could potentially prevent HRHPV infection in 10.2% of men (95% CI, 6.8-14.6, 26 of 255) 2 years later from incident HRHPV covered by the bivalent and quadrivalent vaccine, and 29.4% of men (95% CI, 23.9-35.4, 75/255) from incident HRHPV covered by the nonavalent vaccine. CONCLUSION Though there is high prevalence of anal HPV in men who have sex with men living with human immunodeficiency virus, there was also a high incidence of HRHPV vaccine types in the 2-year follow-up, indicating potential for prevention if these men were not previously infected with HPV vaccine types and were vaccinated at their baseline visit.

Abstract
BACKGROUND Prospective data on the natural history of anal human papillomavirus (HPV) infection are scarce in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). METHODS We analyzed incidence and clearance of HPV-16 and HPV-18 in a French cohort of HIV-infected MSM, aged ≥35 years, followed-up annually (n = 438, 2014-2018). RESULTS Human papillomavirus-16 and HPV-18 incidence were similar (~10% incident infections at 24 months). Human papillomavirus-16 incidence was higher among high-grade versus no lesion at baseline (adjusted incidence rate ratio = 3.0; 95% confidence interval, 1.07-8.18). Human papillomavirus-16 cleared significantly slower than HPV-18 (32% versus 54% by 24 months). CONCLUSIONS In conclusion, anal HPV-16 is more persistent than HPV-18, and its incidence correlates with a prior detection of high-grade lesions.

Abstract
This study aims to investigate the prevalence and genotype distribution of anal human papillomavirus (HPV) infection among men with different sexual orientations with or without human immunodeficiency virus (HIV) in China. A cross-sectional study was conducted during 2016-2017 in Taizhou City, Zhejiang Province. Convenient sampling was used to recruit male participants from HIV voluntary counselling and testing clinics and Center for Disease Control and Prevention. A face-to-face questionnaire interview was administered and an anal-canal swab was collected for HPV genotyping. A total of 160 HIV-positive and 113 HIV-negative men participated in the study. The prevalence of any type HPV was 30.6% for heterosexual men, 74.1% for homosexual and 63.6% for bisexual men among HIV-positive participants, while the prevalence was 8.3%, 29.2% and 23.8% respectively among HIV-negatives. The most prevalent genotypes were HPV-58 (16.9%), HPV-6 (15.6%) and HPV-11 (15.0%) among HIV-positive men, and were HPV-16 (4.4%), HPV-52 (4.4%) and HPV-6 (3.5%) among HIV-negative men. Having ever had haemorrhoids and having ever seen blood on tissue after defaecation was associated with HPV infection. One-fourth of the HPV infections in this study population can be covered by the quadrivalent vaccine in market. The highly prevalent anal HPV infection among men especially HIV-infected men calls for close observation and further investigation for anal cancer prevention.

Abstract
INTRODUCTION Gay, bisexual and other men who have sex with men (gbMSM) have an increased risk of human papillomavirus (HPV) infection and HPV-associated diseases, such as anal cancer and anogenital warts. A carrageenan-based lubricant could prevent HPV infection, thereby reducing the disease burden in this population. This paper describes the protocol for the Lubricant Investigation in Men to Inhibit Transmission of HPV Infection (LIMIT-HPV) study, an ongoing randomised controlled trial (RCT), evaluating efficacy of a carrageenan-based personal lubricant in reducing type-specific anal HPV incidence and prevalence among sexually active gbMSM, efficacy by HIV status, safety and tolerability of the gel and participant adherence to the intervention. METHODS AND ANALYSIS The study is a double-blinded, placebo-controlled RCT. Volunteer gbMSM 18 years and older are randomly assigned 1:1 to receive the treatment (a self-applied anal microbicide gel with carrageenan) or placebo (a self-applied placebo gel). At each visit, computerised questionnaires are used to collect data on sociodemographic and clinical variables, lifestyle, sexual behaviour and the gels' safety and tolerability. At baseline and each follow-up visit (months 1, 2, 3, 6, 9 and 12), nurses collect anal specimens tested for 36 HPV types (linear array assay). HIV status is determined at baseline and 12 months. The primary outcome is incidence of type-specific anal HPV infection(s) undetected at baseline. Secondary outcomes are prevalence of type-specific anal HPV infection, safety, tolerability and adherence. We aim to recruit 380 participants to attain the study's objectives. Data will be analysed using intention-to-treat and per-protocol approaches with subgroup analyses by HIV status. ETHICS AND DISSEMINATION Ethics approval was obtained by the Research Ethics Boards of McGill University, the McGill University Health Centre, Concordia University and Centre Hospitalier de l'Université de Montréal. Trial results will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER NCT02354144.

Abstract
BACKGROUND Some studies on human papillomavirus (HPV) provide not only type-specific incidence rates (IR), but also IRs of HPV groupings (e.g. the nonavalent grouping). We made an inventory of the different approaches used to calculate such IRs and assessed their impact on the estimated IRs of HPV groupings. METHODS We performed a systematic review assessing all approaches used in literature to estimate IRs. Subsequently we applied these approaches to data of a Dutch cohort study on HPV in men who have sex with men (H2M). IRs were estimated for six different HPV groupings. RESULTS The systematic review yielded six different approaches (A-F) for estimating the IRs, varying in exclusion criteria at baseline, and the definitions of an incident event and person-time. Applying these approaches to the H2M dataset (n = 749), we found differences in the number of participants at risk, number of incidents events, person-time, and IR. For example, for the nonavalent grouping, depending on the approach chosen, the IR varied between 3.09 and 6.54 per 100 person-months. CONCLUSION In published studies different epidemiological assumptions are used to estimate IRs of grouped HPV types, leading to widely differing estimates of IRs. IRs between different studies may therefore not be comparable.

Abstract
Intense research activity in HPV modelling over this decade has prompted the development of additional guidelines to those for general modelling. A specific framework is required to address different policy questions and unique complexities of HPV modelling. HPV-FRAME is an initiative to develop a consensus statement and quality-based framework for epidemiologic and economic HPV models. Its development involved an established process. Reporting standards have been structured according to seven domains reflecting distinct policy questions in HPV and cancer prevention and categorised by relevance to a population or evaluation. Population-relevant domains are: 1) HPV vaccination in pre-adolescent and young adolescent individuals; 2) HPV vaccination in older individuals; 3) targeted vaccination in men who have sex with men; 4) considerations for individuals living with HIV and 5) considerations for low- and middle-income countries. Additional considerations applicable to specific evaluations are: 6) cervical screening or integrated cervical screening and HPV vaccination approaches and 7) alternative vaccine types and alternative dosing schedules. HPV-FRAME aims to promote the development of models in accordance with an explicit framework, to better enable target audiences to understand a model's strength and weaknesses in relation to a specific policy question and ultimately improve the model's contribution to informed decision-making.

Abstract
Background We aimed to assess whether sexual exposure may explain all incident anal human papillomavirus (HPV) detections among men who have sex with men (MSM). Methods A longitudinal study among MSM was conducted between 2010 and 2013 with visits every 6 months and up to 24 months of follow-up. Risk-factor questionnaires, blood samples, and anal and penile self-swabs were collected at each visit. Self-swabs were used for detection and genotyping of HPV by the broad spectrum L1 based SPF10 PCR DNA/enzyme immunoassay LiPA25 system. Serum samples were tested for high-risk HPV (hrHPV) antibodies. Incident anal HPV detection rates among sexually non-, low, and highly exposed MSM were compared. Factors associated with incident anal hrHPV detection were assessed using multivariable Cox regression. Results Seven hundred fourteen men (median age, 40 years; 39% human immunodeficiency virus [HIV] infected) were included in the analysis. Incident anal detections of all hrHPV types were observed among both sexually nonexposed and exposed MSM. In multivariable analyses, being highly sexually exposed, being HIV infected, and having a penile HPV infection were positively associated with incident anal HPV detection; those reporting more sex partners had a nonsignificantly increased risk of HPV detection. Conclusions Incident anal hrHPV detection is common among recently nonexposed MSM, suggesting that a reactivated latent HPV infection instead of an incident infection may underlie incident HPV detection.

Abstract
BACKGROUND Anal cancer incidence increased markedly in people living with HIV (PLWHIV) after the introduction of HAART, but in a few setting settings, recent declines have been reported. We report the incidence and time trends of anal cancer in PLWHIV in Australia. STUDY DESIGN A data linkage study between the National HIV Registries and the Australian Cancer Database. METHODS Cases of anal squamous cell carcinoma (ASCC) in Australians aged 16 years and above diagnosed with HIV between 1982 and 2012 were identified. Standardized incidence ratios (SIRs) were calculated to compare incidence with that of the general population. Poisson regression models were developed to describe the time trends of ASCC over time and to compare ASCC risk within subgroups of PLWHIV. RESULTS Among 28 696 individuals, a total of 129 cases of ASCC were identified. The crude incidence was 36.3 per 100 000 person-years and it increased sharply from 14.8 to 62.1 per 100 000 person-years between 1982-1995 and 2009-2012 (P trend <0.001). The SIR was 35.3 (95% confidence interval 29.5-42.0), and there was an inverse association between SIR and increasing age (P trend <0.001). In multivariate analyses, ASCC incidence was significantly higher in recent years (P trend <0.001), in those who acquired HIV through male homosexual contact (P = 0.002), and in those who had a history of AIDS (P < 0.001). CONCLUSION PLWHIV in Australia are at markedly higher risk of anal cancer. Unlike in some industrialized countries with a mature HIV epidemic, the incidence of anal cancer is still increasing in this population in Australia.

Abstract
INTRODUCTION Young men who have sex with men (YMSM) are at high risk to contract human papillomavirus (HPV). While an effective vaccination exists, its use among YMSM is markedly lower compared to non-MSM and women. This study compares scaling up HPV vaccination in conjunction with other prevention strategies. METHODS An agent-based model of urban YMSM (≤26 years of age) reflective of the demography of Philadelphia, PA, simulated for up to ten years of follow-up to examine anal and oral transmission of the HPV genotypes covered in the nonavalent (9v) vaccine: 6, 11, 16, 18, 31, 33, 45, 52, 58. Starting HPV prevalences ranged from a high of 18% (type 6) to a low of 6% (type 31); overall 65% of individuals carried any HPV genotype. Simulated levels of vaccination were ranged from 0% to 13% (present-day level), 25%, 50%, 80% (Healthy People 2020 target), and 100% in conjunction with condom use and HIV seroadaptive practices. The primary outcome was the relative reduction in HPV infection. RESULTS Compared to present-day vaccination levels (13%), scaling-up vaccination led to expected declines in 10-year post-simulation HPV prevalence. Anal HPV (any 9v types) declined by 9%, 27%, 46%, and 58% at vaccination levels of 25%, 50%, 80%, and 100%, respectively. Similarly, oral HPV (any 9v types) declined by 11%, 33%, 57%, and 71% across the same levels of vaccine uptake. Comparing the prevention strategies, condoms blocked the greatest number of anal transmissions when vaccination was at or below present-day levels. For oral transmission, vaccination was superior to condom use at all levels of coverage. CONCLUSIONS Public health HPV preventions strategies should continue to emphasize the complementary roles of condoms and vaccination, especially for preventing oral infection. Improving vaccination coverage will ultimately have the greatest impact on reducing HPV infection among YMSM.

PLoS Med 2019; 16:e1002756.

Abstract
BACKGROUND Men who have sex with men (MSM) are at high risk for anal cancer, primarily related to human papillomavirus genotype 16 (HPV16) infections. At 8.5 per 100,000 per year, the incidence rate of anal cancer among MSM is similar to that of cervical cancer among adult women in the Netherlands. However, MSM are not included in most HPV vaccination programs. We explored the potential effectiveness of prophylactic immunization in reducing anogenital HPV16 transmission among MSM in the Netherlands. METHODS AND FINDINGS We developed a range of mathematical models for penile-anal HPV16 transmission, varying in sexual contact structure and natural history of infection, to provide robust and plausible predictions about the effectiveness of targeted vaccination. Models were informed by an observational cohort study among MSM in Amsterdam, 2010-2013. Parameters on sexual behavior and HPV16 infections were obtained by fitting the models to data from 461 HIV-negative study participants, considered representative of the local MSM population. We assumed 85% efficacy of vaccination against future HPV16 infections as reported for HIV-negative MSM, and age-specific uptake rates similar to those for hepatitis B vaccination among MSM in the Netherlands. Targeted vaccination was contrasted with vaccination of 12-year-old boys at 40% uptake in base-case scenarios, and we also considered the effectiveness of a combined strategy. Offering vaccine to MSM without age restrictions resulted in a model-averaged 27.3% reduction (90% prediction interval [PI] 11.9%-37.5%) in prevalence of anal HPV16 infections, assuming similar uptake among MSM as achieved for hepatitis B vaccination. The predicted reduction improved to 46.1% (90% PI 21.8%-62.4%) if uptake rates among MSM were doubled. The reductions in HPV16 infection prevalence were mostly achieved within 30 years of a targeted immunization campaign, during which they exceeded those induced by vaccinating 40% of preadolescent boys, if started simultaneously. The reduction in anal HPV16 prevalence amounted to 74.8% (90% PI 59.8%-93.0%) under a combined vaccination strategy. HPV16 prevalence reductions mostly exceeded vaccine coverage projections among MSM, illustrating the efficiency of prophylactic immunization even when the HPV vaccine is given after sexual debut. Mode of protection was identified as the key limitation to potential effectiveness of targeted vaccination, as the projected reductions were strongly reduced if we assumed no protection against future infections in recipients with prevalent infection or infection-derived immunity at the time of immunization. Unverified limitations of our study include the sparsity of data to inform the models, the omission of oral sex in transmission to the penile or anal site, and the restriction that our modeling results apply primarily to HIV-negative MSM. CONCLUSIONS Our findings suggest that targeted vaccination may generate considerable reductions in anogenital HPV16 infections among MSM, and has the potential to accelerate anal cancer prevention, especially when combined with sex-neutral vaccination in preadolescence.

Abstract
Background Anal human papillomavirus (HPV) infection, most notably HPV16, the central cause of anal cancer, is increased by anal sexual intercourse and worsened by human immunodeficiency virus (HIV)-positivity. Methods A systematic review and meta-analysis of type-specific anal HPV prevalence in men, compared according to sexual preference, HIV status, and, when available, anal cytopathology. Results Seventy-nine eligible studies included: 1805 HIV-negative men who have sex with women (MSW), 924 HIV-positive MSW, 8213 HIV-negative men who have sex with men (MSM), and 12758 HIV-positive MSM. Irrespective of anal cytopathology, HPV16 prevalence was significantly higher in MSM than MSW, both among HIV-negative (14% vs 3%; prevalence ratio (PR) 4.7; 95% confidence interval [CI] 2.5-8.9) and HIV-positive men (30% vs 11%; PR = 2.8; 95% CI, 1.9-4.1). Likewise, HPV16 was significantly higher in HIV-positive than HIV-negative men, both among MSW (PR = 3.5; 95% CI, 1.6-7.7) and MSM (PR = 2.1; 95% CI, 1.8-2.5). Anal HPV16 prevalence was similar between HIV-positive MSW and HIV-negative MSM. For MSM, anal HPV16 prevalence was significantly higher from studies with anal cytopathology, suggesting population sampling effects. Conclusion Sexual preference and HIV infection are independent strong determinants of male anal HPV16 infection, confirming HIV-positive MSM as priorities for anal cancer prevention.

Abstract
AIM HIV-infected men who have sex with men (MSM) show the highest prevalence of anal HPV infection. Anal prevalence of the HPVs targeted by the quadrivalent HPV vaccine (4vHPV) and nonavalent HPV vaccine (9vHPV) was estimated in this population. MATERIALS & METHODS Anal specimens were collected from HIV-infected MSM attending a sexually transmitted infection/HIV center. Specimens were analyzed using the Linear Array HPV Genotyping Test. RESULTS A total of 49.5 and 71.2% of the 313 enrolled MSM harbored at least one of the 4vHPV and 9vHPV types, respectively. A significantly decreasing trend was observed for the prevalence of both 4vHPV (p = 0.04) and 9vHPV types (p < 0.001) across age classes. CONCLUSION A substantial proportion of HIV-infected MSM do not harbor a current anal infection with vaccine-preventable HPVs. The potential benefit of the 4vHPV versus 9vHPV vaccination in these subjects, including older MSM, should be investigated.

Evidence of synergistic relationships between HIV and Human Papillomavirus (HPV): systematic reviews and meta-analyses of longitudinal studies of HPV acquisition and clearance by HIV status, and of HIV acquisition by HPV status. J Int AIDS Soc 2018; 21:e25110. [PMID: 29873885 PMCID: PMC5989783 DOI: 10.1002/jia2.25110] [Citation(s) in RCA: 92] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Accepted: 03/27/2018] [Indexed: 12/17/2022] Open
Abstract
INTRODUCTION Observational studies suggest HIV and human papillomavirus (HPV) infections may have multiple interactions. We reviewed the strength of the evidence for the influence of HIV on HPV acquisition and clearance, and the influence of HPV on HIV acquisition. METHODS We performed meta-analytic systematic reviews of longitudinal studies of HPV incidence and clearance rate by HIV status (review 1) and of HIV incidence by HPV status (review 2). We pooled relative risk (RR) estimates across studies using random-effect models. I2 statistics and subgroup analyses were used to quantify heterogeneity across estimates and explore the influence of participant and study characteristics including study quality. Publication bias was examined quantitatively with funnel plots and subgroup analysis, as well as qualitatively. RESULTS AND DISCUSSION In review 1, 37 publications (25 independent studies) were included in the meta-analysis. HPV incidence (pooled RR = 1.55, 95% CI: 1.29 to 1.88; heterosexual males: pooled RR = 1.95, 95% CI: 1.62, 2.34; females: pooled RR = 1.63, 95% CI: 1.26 to 2.11; men who have sex with men: pooled RR = 1.36, 95% CI: 1.01 to 1.82) and high-risk HPV incidence (pooled RR = 2.20, 95% CI: 1.90 to 2.54) was approximately doubled among people living with HIV (PLHIV) whereas HPV clearance rate (pooled RR = 0.53, 95% CI: 0.42 to 0.67) was approximately halved. In review 2, 14 publications (11 independent studies) were included in the meta-analysis. HIV incidence was almost doubled (pooled RR = 1.91, 95% CI 1.38 to 2.65) in the presence of prevalent HPV infection. There was more evidence of publication bias in review 2, and somewhat greater risk of confounding in studies included in review 1. There was some evidence that adjustment for key confounders strengthened the associations for review 2. Misclassification bias by HIV/HPV exposure status could also have biased estimates toward the null. CONCLUSIONS These results provide evidence for synergistic HIV and HPV interactions of clinical and public health relevance. HPV vaccination may directly benefit PLHIV, and help control both HPV and HIV at the population level in high prevalence settings. Our estimates of association are useful for mathematical modelling. Although observational studies can never perfectly control for residual confounding, the evidence presented here lends further support for the presence of biological interactions between HIV and HPV that have a strong plausibility.

Abstract
BACKGROUND Anal cytology may be useful for evaluating lesions associated with human papillomavirus (HPV) in individuals at increased risk for anal cancer. METHODS Liquid-based cytology was used to assess anal cytological lesions among human immunodeficiency virus (HIV)-infected and HIV-uninfected men who have sex with men (MSM). The Linear Array HPV genotyping test was used for HPV detection. RESULTS This cross-sectional study included 1021 MSM, of whom 388 were HIV-infected (38.0%). Anal cytological lesions (atypical squamous cells of undetermined significance or more severe [ASCUS+]) were observed in 32.5% and 53.2% of the HIV-uninfected and HIV-infected individuals, respectively (P < .0001). The highest ASCUS + prevalence was observed among ≥45-year-old HIV-uninfected MSM (37.3%) and 25-to 29-year-old HIV-infected MSM (66.7%). High-grade squamous intraepithelial lesions (HSILs) peaked in ≥ 45-year-old HIV-uninfected subjects and 35- to 39-year-old HIV-infected subjects. Individuals with anal infections with high-risk (HR) HPV types were 3 to 4 times more likely to have an ASCUS + report. An HPV-16 and/or HPV-18 infection increased the odds of HSIL or more severe cytology (HSIL+) for HIV-infected MSM almost 4 times. MSM concurrently infected with HR and low-risk HPVs were significantly more likely to have low-grade squamous intraepithelial lesions or more severe cytology (LSIL+) than those infected with only HR types. No significant associations were found between cytological abnormalities and the HIV load and nadir and current CD4 + counts. CONCLUSIONS The prevalence of anal cytological lesions is high in MSM, even in HIV-infected individuals treated with combined antiretroviral therapy. In these subjects, HSILs occur more frequently and at a younger age in comparison with HIV-uninfected counterparts. Specific diagnostic procedures should be implemented to manage individuals at increased risk for anal cancer with an abnormal anal Papanicolaou test.

Abstract
INTRODUCTION Here we present the case of a 56-year-old human immunodeficiency virus (HIV)-infected man with multiple anal condylomas and positivity for human papilloma virus (HPV) 18 on anal brushing. Biopsies of the anal mucosa led to the diagnosis of Bowen's disease and a subsequent pelvic magnetic resonance imaging (MRI) scan evidenced multiple reactive lymphoadenopathies and large intra-anal condylomas. The patient was treated with a complete excision of Bowen's lesion and with a 4 months course of supplementation with a high concentration multistrain probiotic formulation administered orally and by rectal instillation with the purpose to reduce local inflammation and to enhance local mucosal immunity. CONCLUSION An MRI performed at the end of the supplementation period evidenced the clearance of the anal condylomas previously described and no evidence of residual lymphadenopathies. Trials are therefore required to confirm this therapeutic possibility and for a better understanding of the mechanisms by which this specific probiotic formulation interacts with local epithelium when administered by the anal route.

Abstract
Background Young men who have sex with men (MSM) are at increased risk for human papillomavirus (HPV)-associated disease as a result of HPV infection. Our objective was to characterize the prevalence of high-risk anal HPV infection and factors associated with prevalence in a group of young, primarily black MSM in Houston, Texas. Methods MSM aged 18-29 years were recruited using a respondent-driven sampling method to study HIV and sexually transmitted disease transmission and risk. All engaged in peer-recruitment chains and self-collected anal exfoliated cells. Prevalence ratios assessed factors associated with high-risk HPV and HPV types in the 9-valent vaccine. Results Black race was reported by 87% of men. Slightly over one half (53%) were human immunodeficiency virus (HIV) positive. Approximately 75% of men had at least 1 high-risk HPV type, and 39% of HIV-positive men harbored HPV-16. Analysis that controlled for potential confounders revealed that only HIV infection was associated with high-risk HPV infection. Conclusion Black MSM would benefit from increased HPV vaccination efforts, owing to high rates of HPV infection, increased HPV disease, and low vaccination series completion rates in this population.

Abstract
Does anal HPV viral load explain the difference in anal HPV persistence between HIV-negative and -positive men who have sex with men (MSM)? MSM ≥18 years were recruited in Amsterdam, the Netherlands, in 2010-2011. Anal self-swabs were collected every 6 months and genotyped (SPF10 -PCR-DEIA-LIPA25 -system). HPV16 and HPV18 load was determined with a type specific quantitative (q)PCR, and compared between HIV-negative and -positive men using ranksum test. Persistence was defined as ≥3 positive samples for the same HPV-type. Determinants of persistent HPV16/18 infection and its association with HPV16/18 load were assessed with logistic regression. Of 777 recruited MSM, 54 and 22 HIV negative men were HPV16 and HPV18 positive at baseline, and 64 and 39 HIV-positive MSM. The geometric mean titer (GMT) of HPV16 was 19.6 (95%CI 10.1-38.0) and of HPV18 8.6 (95%CI 2.7-27.5) DNA copies/human cell. HPV16 and HPV18 load did not differ significantly between HIV-negative and -positive MSM (P = 0.7; P = 0.8, respectively). In multivariable analyses HPV16 load was an independent determinant of HPV16 persistence (OR 1.8, 95%CI 1.3-2.4). No difference in anal HPV viral load was found between HIV-positive and HIV-negative MSM. HPV 16/18 viral load is an independent determinant of type-specific persistence.

Abstract
Squamous cell carcinoma of anus (SCCA) is one of the most frequent non-AIDS-defining diseases in HIV patients, mainly in men who have sex with men (MSM), and it is associated with human papillomavirus (HPV) infection.To determine the prevalence of high-risk HPV (HR-HPV) genotypes, premalignant lesions (HSIL) and SCCA in a cohort of HIV-positive MSM; to study the distribution of HPV genotypes according to anal histology results; and to analyze risk factors for this infection.This prospective single-center study was conducted between May 2010 and September 2016. At the study visit, cotton swabs were used to collect anal samples for cytology study in ThinPrep Pap Test liquid medium (Thin Prep Processor 2000, Hologic Corp, USA), and for HPV PCR (Linear Array HPV Genotyping Test). After, high-resolution anoscopy (HRA) (Zeiss 150 fc) was carried out. Logistic regression analysis was performed to identify risk factors for HR-HPV infection.The study included 319 patients, with mean age of 36.7 years; HR-HPV was detected in 81.3%. The prevalence of HSIL was 13.5% and SCCA was 0.3%. With regard to the distribution of HPV genotypes according to histology results, HPV 16 was the most frequent genotype in normal anal mucosa (26.7%), in LSILs (36.9%), and in HSILs (38%). In multivariate analysis, CD4 nadir < 200 cells/μL was the factor associated with infection by HR-HPV (OR 3.66, 95% CI 1.05%-12.75%).HIV-positive MSM showed a high prevalence of HSIL+ lesions and of infection by oncogenic HPV, which appears to be favored by a deficient immune system. HPV 16 was the most frequently isolated genotype in anal mucosa, regardless of lesion type.

Abstract
We studied DNA methylation patterns of human papillomavirus (HPV) and tumor suppressor gene EPB41L3 in 148 anal and perianal biopsies to determine whether high levels of methylation would be associated with anal intraepithelial neoplasia (AIN). The most prevalent HPV type was HPV16, detected in 54% of the 30 benign biopsies, 33% of the 43 low-grade AIN (lgAIN), 82% of the 59 high grade AIN (hgAIN) and 4 of the 5 anal cancers. A methylation score was developed (0.561*HPV16me+0.439*EPB41L3) which had increasing values with severity of disease: the mean was 8.1% in benign, 13.2% in lgAIN, 22.3% in hgAIN and 49.3% in cancers (p < 0.0001). The methylation score as a triage classifier at a cut-off of 8.8 gave a sensitivity of 90.6% (95% CI: 82.8, 96.9), specificity of 50.7% (95% CI: 39.7, 61.6) and area under the curve of 0.82 (95% CI: 0.75-0.89) for separating hgAIN and cancer from benign and lgAIN biopsies. We conclude that methylation of HPV16 and EPB41L3 show highly significant association with increasing severity of AIN and cancer and may be useful as biomarkers in anal disease.

[PMID: 27986968 PMCID: PMC5520248 DOI: 10.1136/sextrans-2016-052786] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2016] [Revised: 11/03/2016] [Accepted: 11/28/2016] [Indexed: 11/07/2022] Open
Abstract
OBJECTIVES Female anorectal Chlamydia trachomatis (chlamydia) infections are common irrespective of recent anal sex. We explored the role of anorectal infections in chlamydia transmission and estimated the impact of interventions aimed at improved detection and treatment of anorectal infections. METHODS We developed a pair compartmental model of heterosexuals aged 15-29 years attending STI clinics, in which women can be susceptible to or infected with chlamydia urogenitally and/or anorectally and men urogenitally. Transmission probabilities per vaginal and anal sex act, together with an autoinoculation probability, were estimated by fitting to anatomic site-specific prevalence data (14% urogenital; 11% anorectal prevalence). We investigated the 10-year reduction in female chlamydia prevalence of interventions (universal anorectal testing of female STI clinic attendees or doxycycline use for urogenital chlamydia) relative to continued current care (anorectal testing on indication and doxycycline for anorectal and azithromycin for urogenital chlamydia). RESULTS The transmission probability per anal sex act was 5.8% (IQR 3.0-8.3%), per vaginal sex act 2.0% (IQR 1.7-2.2%) and the daily autoinoculation probability was 0.7% (IQR 0.5-1.0%). More anorectal chlamydia infections were caused by autoinoculation than by recent anal sex. Universal anorectal testing reduced population prevalence modestly with 8.7% (IQR 7.6-9.7%), yet the reduction was double that of doxycycline use for urogenital infections (4.3% (IQR 3.5-5.3%)) relative to continued current care. CONCLUSIONS Autoinoculation between anatomic sites in women might play a role in sustaining high chlamydia prevalence. A shift to more anorectal testing of female STI clinic attendees may be considered for its (albeit modest) impact on reducing prevalence.

Modeling the Mechanisms by Which HIV-Associated Immunosuppression Influences HPV Persistence at the Oral Mucosa. PLoS One 2017; 12:e0168133.

Abstract
Human immunodeficiency virus (HIV)-infected patients are at an increased risk of co-infection with human papilloma virus (HPV), and subsequent malignancies such as oral cancer. To determine the role of HIV-associated immune suppression on HPV persistence and pathogenesis, and to investigate the mechanisms underlying the modulation of HPV infection and oral cancer by HIV, we developed a mathematical model of HIV/HPV co-infection. Our model captures known immunological and molecular features such as impaired HPV-specific effector T helper 1 (Th1) cell responses, and enhanced HPV infection due to HIV. We used the model to determine HPV prognosis in the presence of HIV infection, and identified conditions under which HIV infection alters HPV persistence in the oral mucosa system. The model predicts that conditions leading to HPV persistence during HIV/HPV co-infection are the permissive immune environment created by HIV and molecular interactions between the two viruses. The model also determines when HPV infection continues to persist in the short run in a co-infected patient undergoing antiretroviral therapy. Lastly, the model predicts that, under efficacious antiretroviral treatment, HPV infections will decrease in the long run due to the restoration of CD4+ T cell numbers and protective immune responses.

Abstract
Human papillomavirus (HPV) infection is mostly asymptomatic, but may also have many diverse clinical signs encompassing benign ano-genital lesions, and carcinomas. Recently, interest has also particularly focused on anal cancer since, over the last decades, its incidence has been greatly increasing in developed countries, both in women and men and is drastically higher in specific risk groups, such as men who have sex with men (MSM) and HIV-1 infected individuals. Approximately 88% of anal cancer cases worldwide are associated with HPV infection. This review summarizes our current understanding of anal HPV infection, discussing its epidemiology and risk factors in various populations, and the state of the art in the detection of anal HPV infection and its related lesions through both cytology and histology. Finally, we discuss the clinical management and therapy for these lesions.

Abstract
The number of infectious disease outbreaks and the number of unique pathogens responsible have significantly increased since the 1980s. HIV-positive men who have sex with men (MSM) are a vulnerable population with regards to the introduction, spread and clinical consequences of (newly introduced) STIs. After the introduction of combination antiretroviral treatment (cART), the incidence of sexually acquired hepatitis C virus (HCV) infection and human papillomavirus (HPV)-induced anal cancers have significantly increased among HIV-positive MSM. The introduction and expansion of HCV is the result of increased sexual risk behaviour and sexually acquired mucosal trauma within large interconnected networks of HIV-positive MSM in particular. With the availability of cART, postexposure and pre-exposure prophylaxis (PEP and PrEP) and direct-acting antivirals (DAAs) for HCV, less concern for HIV and HCV might require a new approach to develop effective behavioural intervention strategies among MSM. The marked rise in HPV-induced anal cancers can be ascribed to the long-term immunologic defects in an ageing population affected by HIV. More evidence with regards to effective treatment options for anal dysplastic lesions and the usefulness of anal malignancy screening programmes is urgently needed. Most anal cancers in the future generation of HIV-positive MSM could be prevented with the inclusion of boys in addition to girls in current HPV vaccination programmes.

Anal human papillomavirus in HIV-uninfected men who have sex with men: incidence and clearance rates, duration of infection, and risk factors. Clin Microbiol Infect 2016; 22:1004.e1-1004.e7.

Abstract
Little is known regarding the natural history of anal human papillomavirus (HPV) infection. We aimed to evaluate incidence and clearance rates, their risk factors, and duration of anal HPV infection in HIV-uninfected men who have sex with men (MSM). A longitudinal study was conducted. Anal samples were analysed using the Linear Array HPV Genotyping test. Incidence and clearance rates, and corresponding risk factors, were estimated using a two-state Markov model. Overall, 155 MSM (median age 33.4 years) attending the largest sexually transmitted infection (STI) centre in Rome, Italy, were followed for a median of 12.2 months (Q1-Q3: 7.0-18.1). Incidence and clearance rates for any HPV were 85.6 (95% CI: 58.4-125.4) and 35.6 (95% CI: 24.7-51.5) × 1000 person-months, respectively; the median duration of infection was 9.4 months (Q1-Q3: 7.5-12.1). Receptive anal sex emerged as the only risk factor for the acquisition of any HPV (Hazard Ratio, HR = 2.65, 95% CI: 1.16-6.06). The incidence rates for carcinogenic and non-carcinogenic types were 42.3 (95% CI: 29.2-61.4) and 29.2 (95% CI: 19.5-43.7) × 1000 person-months, respectively (p = 0.13); their clearance rates were 62.9 (95% CI: 45.1-87.7) and 65.7 (95% CI: 47.4-91.0) × 1000 person-months, respectively (p = 0.83). HPV16 showed the lowest clearance rate among carcinogenic types (59.7 × 1000 person-months), and a duration of infection of 16.8 months. In conclusion, a higher incidence rate was observed for carcinogenic compared to non-carcinogenic HPV types, although the difference was not significant. HPV16 emerged as the type with the longest duration of infection and the lowest clearance rate among carcinogenic types.

Abstract
BACKGROUND The epidemiology of oral human papillomavirus (HPV) infection in men who have sex with men (MSM) differs from anogenital HPV infection. The impact of HPV vaccination has, to date, largely focussed on anogenital outcomes. Vaccination of MSM in the UK has been recommended and, if implemented, baseline estimates of oral HPV prevalence will be useful. METHODS We searched Medline, Embase and psycINFO databases for studies reporting prevalence, incidence, and clearance of oral HPV infection in MSM. We performed a random-effects meta-analysis and meta-regression on prevalence estimates and summarised within-study risk factors for oral HPV DNA detection and incidence/clearance rates. We also performed a meta-analysis of the effect of MSM on oral HPV prevalence compared to heterosexual men. RESULTS 26 publications were identified. The pooled prevalence of oral HPV16 from twelve estimates was 3.0% (95%CI 0.5-5.5) in HIV-negative and 4.7% (95%CI 2.1-7.3) in HIV-positive MSM. Median age of study participants explained 38% of heterogeneity (p<0.01) in HPV prevalence estimates (pooled = 17% and 29% in HIV-negative and HIV-positive, respectively; 22 estimates). Nine studies compared MSM to heterosexual men and found no difference in oral HPV prevalence (pooled OR 1.07 (95%CI 0.65-1.74)). The clearance rate was higher than incidence within studies. Type-specific concordance between oral and anogenital sites was rare. CONCLUSION There was substantial heterogeneity between estimates of oral HPV prevalence in MSM populations that was partly explained by HIV status and median age.
