Oncogenic Oral Human Papillomavirus Clearance Patterns over 10 Years. Cancer Epidemiol Biomarkers Prev 2024; 33:516-524. [PMID: 38294704 PMCID: PMC10990780 DOI: 10.1158/1055-9965.epi-23-1272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 12/06/2023] [Accepted: 01/29/2024] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND Effective screening for oropharyngeal cancer is lacking. Four oncogenic HPV clearance definitions were explored to understand long-term natural history for persistent oncogenic oral HPV (oncHPV), the precursor of oropharyngeal cancer. METHODS Prospective multicenter cohort of participants living with/at-risk for HIV, with oral rinse and gargle samples collected every 6 to 12 months for up to 10 years and tested for oncHPV. HPV clearance definitions included 1 (clear1), 2 (clear2), 3 (clear3) consecutive negatives, or being negative at last two visits (clearlast). RESULTS Median time to clearance of oncHPV exceeded 2 years for conservative definitions (clear3: 2.38, clearlast: 2.43), but not lenient (clear1: 0.68, clear2: 1.15). By clear3, most incident infections cleared at 2, 5, 8 years (55.1%, 75.6%, 79.1%), contrary to prevalent infections (37.1%, 52.5%, 59.5%, respectively). In adjusted analysis, prevalent oncHPV, older age, male sex, and living with HIV were associated with reduced clearance. Of 1,833 subjects screened, 13.8% had prevalent oncHPV and 47.5% of those infections persisted ≥5 years, representing 6.5% of persons screened. Two men with prevalent oral HPV16 developed incident oropharyngeal cancer [IR = 1.62 per 100 person-years; 95% confidence interval (CI), 0.41-6.4]. Many with oral HPV16 persisted ≥5 years (and/or developed HPV-oropharyngeal cancer) among those with 2 (72.2%), ≥2 of first 3 (65.7%), or 3 (80.0%) consecutive positive oHPV16 tests, but not after 1 (39.4%). CONCLUSIONS In our 10-year study, most incident infections cleared quickly. However, half of prevalent oncHPV persisted ≥5 years, suggesting increased risk with persistent oncHPV at >2 visits. IMPACT We identified groups with persistent oncHPV at increased risk of oropharyngeal cancer and contextualized risk levels for those with oral HPV16 infection.

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
INTRODUCTION Squamous cell carcinoma of the anus is a common cancer among sexual minority men, especially HIV-positive sexual minority men; however, there is no evidenced-based national screening protocol for detection of anal precancers. Our objective is to determine compliance with annual anal canal self-sampling or clinician-sampling for human papillomavirus (HPV) DNA. METHODS AND ANALYSIS This is a prospective, randomised, two-arm clinical study to evaluate compliance with annual home-based versus clinic-based HPV DNA screening of anal canal exfoliated cells. The setting is primary care community-based clinics. Recruitment is ongoing for 400 HIV-positive and HIV-negative sexual minority men and transgender persons, aged >25 years, English or Spanish speaking, no current use of anticoagulants other than nonsteroidal anti-inflammatory drugs and no prior diagnosis of anal cancer. Participants are randomised to either receive a swab in the mail for home-based collection of an anal canal specimen at 0 and 12 months (arm 1) or attend a clinic for clinician collection of an anal canal specimen at 0 and 12 months (arm 2). Persons will receive clinic-based Digital Anal Rectal Examinations and high-resolution anoscopy-directed biopsy to assess precancerous lesions, stratified by study arm. Anal exfoliated cells collected in the study are assessed for high-risk HPV persistence and host/viral methylation. The primary analysis will use the intention-to-treat principle to compare the proportion of those who comply with 0-month and 12-month sampling in the home-based and clinic-based arms. The a priori hypothesis is that a majority of persons will comply with annual screening with increased compliance among persons in the home-based arm versus clinic-based arm. ETHICS AND DISSEMINATION The study has been approved by the Medical College of Wisconsin Human Protections Committee. Results will be disseminated to communities where recruitment occurred and through peer-reviewed literature and conferences. TRIAL REGISTRATION NUMBER NCT03489707.

Prevalence and genotype distribution of human papillomavirus infection in different anatomical sites among men who have sex with men: A systematic review and meta-analysis.

[PMID: 33527636 DOI: 10.1002/rmv.2219] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 01/07/2021] [Accepted: 01/12/2021] [Indexed: 12/15/2022]
Abstract
Men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviours. In this study, a meta-analytic approach was used to systematically analyse the literature to elucidate the prevalence and genotype distribution of anal, penile, oral and urethral HPV infection among MSM in the world. To carry out this systematic review, five electronic databases including Web of Science, PubMed, Scopus, Embase, and Google Scholar were searched for relevant studies published from January 2012 to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalence was calculated for each anatomical region using a random-effect model weighted by the inverse variance method. The meta-analysis was performed using the "Metaprop" function in the R package Meta. The overall pooled prevalence of anal, penile, oral and urethral HPV infection among MSM were 78.4% (95% confidence interval [CI]: 75.6%-81.0%), 36.2% (95% CI: 29.1%-44.0%), 17.3% (95% CI: 13.6%-21.7%) and 15.4% (95% CI: 7.8%-27.9%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis and oral cavity was HPV-16 (19.9%, 4.9% and 3.1%, respectively). HPV infection is rising in MSM because of high-risk sexual behaviours, suggesting an increased future risk of developing HPV-related diseases and malignancies in this population.

Abstract
Human papillomavirus (HPV) is a DNA virus that causes sexually transmitted infections. The HPV oncoprotein E7 plays a critical role in the regulation of host immunity to promote the immune escape of HPV and the occurrence of cervical cancer or genital warts. Pyroptosis, a highly inflammatory form of programmed cell death, can be induced by inflammasomes and acts as a defense against pathogenic infection. However, whether HPV E7 can regulate cell pyroptosis to evade immune surveillance has not been determined. In this study, we found that HPV E7 could inhibit cell pyroptosis induced by transfection with dsDNA. The activation of the inflammasome, and the production of IL-18 and IL-1β were also restrained by HPV E7. Mass spectrometry and immunoprecipitation showed that HPV E7 interacted with IFI16 and TRIM21. We also discovered that HPV E7 recruited the E3 ligase TRIM21 to ubiquitinate and degrade the IFI16 inflammasome, leading to the inhibition of cell pyroptosis and self-escape from immune surveillance. Thus, our study reveals an important immune escape mechanism in HPV infection and may provide targets for the development of a novel immunotherapeutic strategy to effectively restore antiviral immunity.

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
Objective To estimate the prevalence, incidence and persistence of anal HPV infection and squamous intra-epithelial lesions (SILs) among men living with HIV (MLHIV), and determine their risk factors. Methods We enrolled MLHIV ≥18 years, who attended 6-monthly visits for 18 months. Socio-behavioural data were collected by questionnaire. Clinicians collected blood sample (CD4+ count and HIV plasma viral load), anal swabs (HPV DNA testing) and anal smears (Bethesda classification) at each visit. HPV DNA testing and classification of smears were done at enrolment and last follow-up visit (two time points). Factors associated with persistent anal HPV infection and SILs were evaluated with generalized estimating equations logistic regression and standard logistic regression respectively. Results Mean age of 304 participants was 38 (Standard Deviation, 8) years; 25% reported >1 sexual partner in the past 3 months. Only 5% reported ever having sex with other men. Most (65%) participants were taking antiretroviral treatment (ART), with a median CD4+ count of 445 cells/μL (IQR, 328–567). Prevalence of any-HPV infection at enrolment was 39% (88/227). In total, 226 men had anal HPV DNA results at both enrolment and final visits. Persistence of any-anal HPV infection among 80 men who had infection at enrolment was 26% (21/80). Any persistent anal HPV infection was more frequent among MLHIV with low CD4+ count (<200 vs. >500 cells/μL; aOR = 6.58; 95%CI: 2.41–17.94). Prevalence of anal SILs at enrolment was 49% (118/242) while incidence of SILs among MLHIV who had no anal dysplasia at enrolment was 27% (34/124). Of the 118 men who had anal dysplasia at enrolment, 15% had regressed and 38% persisted by month 18. Persistent anal HPV infection was associated with persistent SILs (aOR = 2.95; 95%CI: 1.08–10.89). ART status or duration at enrolment were not associated with persistent anal HPV infection or persistent SILs during follow-up. Conclusion In spite of a high prevalence of anal HPV, HIV-positive heterosexual men have a low burden of anal HPV related disease. HPV vaccine and effective ART with immunological reconstitution could reduce this burden of infection.
