Integrative literature review on human papillomavirus vaccination recommendations in national immunization programs in select areas in the Asia-Pacific region. Hum Vaccin Immunother 2024; 20:2362449. [PMID: 38925146 PMCID: PMC11210899 DOI: 10.1080/21645515.2024.2362449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 05/28/2024] [Indexed: 06/28/2024] Open
Abstract
There is limited literature on current human papillomavirus (HPV) vaccination in the Asia-Pacific region. This integrative literature review was conducted to describe HPV vaccination programs in Hong Kong, Indonesia, Japan, South Korea, Malaysia, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. Program descriptions, recommendations, f unding, and coverage data were extracted. Twenty-five citations were included. As of 2022, eight of the 10 areas of interest include HPV in their national immunization program (NIP) for school-aged girls; full implementation in Indonesia is expected in 2023 whereas Vietnam's NIP does not include HPV. Singapore also includes HPV vaccination for women (18-26 years). None of the HPV vaccination programs include males. In most areas (n = 7), programs include only one vaccine option. While female HPV NIPs are present in the Asia-Pacific region, opportunities remain to strengthen NIPs in broader populations (e.g., males, catch-up cohorts) to expand public health impact and provide gender equity in HPV vaccination.

Global Type-Specific Genital Human Papillomavirus Prevalence in Men, by Sexual Orientation: A Systematic Review and Meta-Analysis. J Infect Dis 2023; 228:1023-1032. [PMID: 37079383 PMCID: PMC10582913 DOI: 10.1093/infdis/jiad109] [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: 12/01/2022] [Revised: 03/16/2023] [Accepted: 04/18/2023] [Indexed: 04/21/2023] Open
Abstract
BACKGROUND Knowledge on genital type-specific human papillomavirus (HPV) prevalence among men is important for prevention of HPV-related cancers and other diseases. Men who have sex with men (MSM) have higher anal prevalence than men who have sex with women only (MSW) but for genital HPV this is unclear. We performed a systematic review and meta-analysis of type-specific genital HPV prevalence among men, by sexual orientation. METHODS MEDLINE and Embase were used for searching publications reporting on male genital HPV prevalence with data from November 2011 onwards. A random-effects meta-analysis was conducted estimating pooled type-specific and grouped external genital and urethral HPV prevalence. Subgroup analyses were conducted for sexual orientation. RESULTS Twenty-nine studies were eligible. Of those, 13 studies reported prevalence among MSM, 5 among MSW, and 13 studies did not stratify by sexual orientation. The most common genotypes were HPV-6 and HPV-16 for both anatomical locations, although heterogeneity was high. HPV prevalence was similar among studies reporting on MSW, MSM, and men with unknown sexual orientation. CONCLUSIONS Genital HPV is common among men, with HPV-6 and HPV-16 being the most common genotypes. Type-specific HPV genital prevalence appears to be similar among MSM and MSW, which contrasts with earlier findings on anal HPV.

Global and regional estimates of genital human papillomavirus prevalence among men: a systematic review and meta-analysis. Lancet Glob Health 2023; 11:e1345-e1362. [PMID: 37591583 PMCID: PMC10447222 DOI: 10.1016/s2214-109x(23)00305-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 05/26/2023] [Accepted: 06/20/2023] [Indexed: 08/19/2023]
Abstract
BACKGROUND The epidemiology of human papillomavirus (HPV) in women has been well documented. Less is known about the epidemiology of HPV in men. We aim to provide updated global and regional pooled overall, type-specific, and age-specific prevalence estimates of genital HPV infection in men. METHODS We conducted a systematic review and meta-analysis to assess the prevalence of genital HPV infection in the general male population. We searched Embase, Ovid MEDLINE, and the Global Index Medicus for studies published between Jan 1, 1995, and June 1, 2022. Inclusion criteria were population-based surveys in men aged 15 years or older or HPV prevalence studies with a sample size of at least 50 men with no HPV-related pathology or known risk factors for HPV infection that collected samples from anogenital sites and used PCR or hybrid capture 2 techniques for HPV DNA detection. Exclusion criteria were studies conducted among populations at increased risk of HPV infection, exclusively conducted among circumcised men, and based on urine or semen samples. We screened identified reports and extracted summary-level data from those that were eligible. Data were extracted by two researchers independently and reviewed by a third, and discrepancies were resolved by consensus. We extracted only data on mucosal α-genus HPVs. Global and regional age-specific prevalences for any HPV, high-risk (HR)-HPV, and individual HPV types were estimated using random-effects models for meta-analysis and grouped by UN Sustainable Development Goals geographical classification. FINDINGS We identified 5685 publications from database searches, of which 65 studies (comprising 44 769 men) were included from 35 countries. The global pooled prevalence was 31% (95% CI 27-35) for any HPV and 21% (18-24) for HR-HPV. HPV-16 was the most prevalent HPV genotype (5%, 95% CI 4-7) followed by HPV-6 (4%, 3-5). HPV prevalence was high in young adults, reaching a maximum between the ages of 25 years and 29 years, and stabilised or slightly decreased thereafter. Pooled prevalence estimates were similar for the UN Sustainable Development Goal geographical regions of Europe and Northern America, Sub-Saharan Africa, Latin America and the Caribbean, and Australia and New Zealand (Oceania). The estimates for Eastern and South-Eastern Asia were half that of the other regions. INTERPRETATION Almost one in three men worldwide are infected with at least one genital HPV type and around one in five men are infected with one or more HR-HPV types. Our findings show that HPV prevalence is high in men over the age of 15 years and support that sexually active men, regardless of age, are an important reservoir of HPV genital infection. These estimates emphasise the importance of incorporating men in comprehensive HPV prevention strategies to reduce HPV-related morbidity and mortality in men and ultimately achieve elimination of cervical cancer and other HPV-related diseases.

Abstract
BACKGROUND Lichen sclerosus (LS) is an inflammatory disease mostly arising at the genital level. It is unclear whether human papillomaviruses (HPVs) have an etiological significance in LS, and data on their prevalence in patients with LS are controversial. OBJECTIVES The authors assessed alpha, beta, and gamma HPV prevalence in patients with genital LS. The association of HPV positivity with demographic and clinical factors was also investigated. METHODS One hundred thirty-two formalin-fixed, paraffin-embedded LS samples (2016-2020) were retrieved from the archives of a pathology department. Alpha HPVs were genotyped with the INNO-LiPA HPV Genotyping Extra II kit. Beta and gamma HPVs were searched by multiplex Polymerase Chain Reaction. Immunostaining for p16 INK4a was performed on high-risk HPV-positive samples. RESULTS Patients had a median age of 61 years, were mostly women ( n = 73, 55.3%), and with an early disease stage ( n = 79, 59.8%). Alpha HPVs were detected in 12/132 cases (9.1%). Among the 5 high-risk HPV-positive cases, only 2 displayed a strong and diffuse p16 INK4a staining. Beta genus was the most prevalent (35/132, 26.5%) and HPV5 was the most frequent beta genotype (25/132, 18.9%). There were 3 gamma HPV-positive cases among those with a valid result (3/131, 2.3%). Multiple infections with genotypes belonging to different genera were infrequent (3/131, 2.3%). No significant differences in the prevalence of the individual genera were observed according to sex and disease stage. CONCLUSIONS Of the 3 HPV genera, beta genus showed the highest prevalence. Further research is needed to clarify whether the presence of beta HPVs in genital LS has a clinical significance.

Abstract
Abstract
Background
The interest in the HPV status of the male has risen after the discovery of HPV shedding in the semen. To date, there is no consensus on the true prevalence of male HPV infection, yet there is a rising body of evidence suggesting that male HPV infection might negatively affect the sperm parameters.
Main body
The concern that HPV can lead to a couple’s infertility and affect reproductive outcomes had increased after the multiple publications of semen criteria perturbations specifically the asthenospermia associated with HPV infection. An extensive literature review was performed to define the actual frequency of male HPV infection as well as the true extent of sperm analysis perturbations related to the HPV illness. We also intended to define the impact of these infections on reproductive outcomes and to highlight any treatment plans for affected couples.
Conclusion
HPV is a prevalent disease with a rising concern among the male populations given the suggested impact on sperm motility as well as the pregnancy and miscarriage rates post-ART treatment. Vaccines are being studied now as a possible infertility adjunct treatment for males who are already infected.

Abstract
INTRODUCTION Human papillomavirus (HPV) infection is the most common sexually transmissible infection worldwide. Although the prevalence of cervical HPV infection has been extensively reported in women worldwide, few epidemiological studies have examined the prevalence of non-cervical HPV infection among both women and men, especially in China. METHODS AND ANALYSIS PROGRESS-Plus is a national, multisite, cross-sectional study that aims to estimate the prevalence of non-cervical HPV infection in women and men aged 18-60 years residing in mainland China. More specifically, PROGRESS-Plus will estimate the prevalence rate of HPV DNA in oral samples from both women and men, and that of anogenital samples from men. The secondary study objectives are to (1) report the aforementioned prevalence rates by HPV genotype, age and geographical region, (2) examine the concordance (ie, prevalence of the same HPV genotype) between the oral and anogenital samples among men, (3) explore risk factors associated with oral (in both women and men) and anogenital (in men only) HPV infection and (4) describe study participants' health-related quality of life, health behaviour, sexual behaviour and health status. ETHICS AND DISSEMINATION The study protocol and all required documents have been submitted for review and approval to the Independent Ethics Committees of all the participating sites. All participants will provide their written informed consent on study entry, and all the recorded data will be treated as confidential.

Comparison in HPV prevalence between urine and washing samples. J Med Virol 2023; 95:e28110. [PMID: 36042577 DOI: 10.1002/jmv.28110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 08/22/2022] [Accepted: 08/28/2022] [Indexed: 01/11/2023]
Abstract
Although urine and bladder washing samples are commonly used for the cytological evaluation of the bladder mucosa, it has been unknown whether these samples are likely suitable to investigate human papillomavirus (HPV) prevalence in the urinary bladder. The present study aimed to elucidate the appropriateness of spontaneously voided urine or bladder washing in screening HPV infection in the urinary bladder. Urine and bladder washing samples were obtained from 201 patients who underwent transurethral bladder tumor resection. After extracting DNA from both samples, HPV-DNA was examined using a nested polymerase chain reaction with GP5+/6+ and MY09/11 primers. HPV genotyping was performed in the HPV-positive samples. In situ hybridization (ISH) was performed to observe the HPV-DNA localization in urothelial cells among cytological samples and paraffin-embedded tumor tissues in HPV-positive washing samples. HPV prevalence in urine and washing samples were 9.5% and 7.0%, respectively. High-risk HPV prevalence in urine and washing samples was 7.5% and 4.0%, respectively. The most common HPV type was HPV 16, followed by HPV 52 and HPV 18 in both samples. HPV type distribution in both samples was not in agreement (κ = -0.431). The ISH analysis revealed that HPV-DNA signal was observed in urothelial cells of five (55.7%) of nine detectable HPV-positive cytological samples. Six (66.7%) of nine HPV-positive cases had HPV-DNA signals in tumor tissue. The use of washing samples was likely applicable for investigating HPV prevalence in the urinary bladder. HPV-DNA detected in washing samples might be frequently derived from the urinary bladder.

Abstract
OBJECTIVE Most evidence, including recent randomized controlled trials, analysing anal squamous cell carcinoma (SCC) do not consider immunocompromise patient population. The aim of this study was to compare clinical and oncological outcomes among immunocompetent and immunocompromised patients with anal squamous cell carcinoma. METHOD Multicentric retrospective comparative study including 2 cohorts of consecutive patients, immunocompetent and immunocompromised, diagnosed with anal SCC. This study evaluated clinical characteristics, clinical response to radical chemoradiotherapy (CRT) and long-term oncological results including both local and distant recurrence, overall survival (OS) and disease-free survival (DFS). RESULTS A total of 84 patients, 47 (55.6%) female, diagnosed with anal SCC from January 2012 to December 2017 were included, 22 (26%) and 62 (74%) patients in immunocompromised and immunocompetent groups respectively. Patients in immunocompromised group were significantly younger (53 vs. 61 years; P = 0.001), with smaller tumoral size (P = 0.044) and reported higher rates of substance abuse including tobacco use (P = 0.034) and parenteral drug consumption (P = 0.001). No differences were found in administered therapies (P = 301) neither in clinical response to chemoradiotherapy (83 vs. 100%). Moreover, similar 5-year OS (60 vs. 64%; P = 0.756) and DFS (65 vs. 68%; P = 0.338) were observed. CONCLUSION The present study shows no significant differences in long-term oncological results among immunocompetent and immunocompromised patients diagnosed with anal SCC, with a similar oncologic treatment. This evidence might be explained due to the close monitoring and adequate therapeutic control of HIV positive patients.

HPV Vaccination in Young Males: A Glimpse of Coverage, Parental Attitude and Need of Additional Information from Lombardy Region, Italy. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19137763. [PMID: 35805445 PMCID: PMC9265455 DOI: 10.3390/ijerph19137763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 06/04/2022] [Accepted: 06/22/2022] [Indexed: 12/10/2022]
Abstract
Background: In the Lombardy Region, Italy, HPV vaccination is recommended and offered free of charge to 12-years-old males since 2017. The expected vaccination thresholds are still far to be reached. Methods: A cross-sectional survey to investigate parents’ attitudes towards the HPV vaccine and knowledge about HPV was administered to parents of boys aged 6 to 18 years attending a large pediatric hospital for outpatient specialistic evaluations. Two parallel multiple logistic regression analyses were conducted to estimate the odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for attitude towards HPV vaccination and perceived need for more information about HPV vaccination. Results: A positive attitude towards HPV vaccination was found in 74% of interviewed parents. Knowledge of HPV, having a generally positive attitude toward vaccination, and mothers filling in the survey were positively associated with a positive attitude to the HPV vaccine. Parents’ perceived need for more information about HPV vaccination was positively associated with the child’s age, general positive attitude toward vaccination, Christian religion, and positive attitude toward HPV vaccination; knowing that HPV vaccination is free of charge significantly reduced the risk of asking for more information on HPV vaccination. Conclusions: The majority of parents of male children and adolescents in our study have a positive attitude toward HPV vaccination. Attitude toward HPV vaccination and perceived need for more information on HPV vaccination were directly related to a positive attitude toward vaccines in general. In addition, knowledge of HPV and related pathologies favors a positive attitude toward HPV vaccination. Future health programs should target an even wider diffusion of evidence-based information on vaccines in general and on the HPV vaccine in young males, to support a positive attitude toward vaccines in the general population.

Chan PSF, Fang Y, Chidgey A, Fong F, Ip M, Wang Z. Would Chinese Men Who Have Sex With Men Take Up Human Papillomavirus (HPV) Screening as an Alternative Prevention Strategy to HPV Vaccination? Front Med (Lausanne) 2022; 9:904873. [PMID: 35721088 PMCID: PMC9205561 DOI: 10.3389/fmed.2022.904873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Accepted: 05/09/2022] [Indexed: 11/13/2022] Open
Abstract
Background Men who have sex with men (MSM) are at high risk for human papillomavirus (HPV) infection. A community-based organization (CBO)-private clinic service model promoting HPV vaccination among MSM was implemented in Hong Kong. The aim of this study was to evaluate the effectiveness of this service model in increasing HPV screening among MSM. Methods This was a secondary analysis of the CBO-private clinic service model in increasing HPV screening among MSM. Participants were Hong Kong Chinese-speaking MSM aged 18–45 years who had never received HPV vaccination. All participants completed a telephone survey at baseline before receiving online intervention promoting HPV vaccination and completed another telephone survey 12 months afterward. Results A total of 350 participants completed a baseline telephone survey and received interventions promoting HPV vaccination. Among 274 participants being followed up at Month 12, 33 (12.0%) received any type of HPV screening during the study period. Such uptake rate was similar to the prevalence of HPV screening in the past year measured at baseline (12.0 vs. 9.9%, p = 0.43). More MSM preferred HPV vaccination or HPV vaccination plus HPV screening, and very few preferred HPV screening alone. After adjusting for significant baseline characteristics, higher perceived susceptibility to HPV (adjusted odds ratio (AOR): 1.16, 95% confidence interval (CI): 1.00–1.34) and receiving HPV vaccination during the study period (AOR: 7.03, 95% CI: 3.07–16.13) were significantly associated with higher HPV screening uptake. Conclusions The CBO-private clinic service model promoting HPV vaccination had limited impact in increasing HPV screening among MSM in Hong Kong. MSM in Hong Kong may not use HPV screening as an alternative prevention strategy to HPV vaccination. Future programs preventing HPV-related diseases among MSM in Hong Kong should focus on HPV vaccination promotion.

Abstract
Background Genital human papillomavirus (HPV)-infections are common in the general population and are responsible for relevant numbers of epithelial malignancies. Much data on the HPV-prevalence is available for secondary immunodeficiencies, especially for patients with human immunodeficiency virus (HIV)-infection. Little is known about the genital HPV-prevalence in patients with primary immunodeficiencies (PIDs). Methods We performed a cross-sectional study of patients with PIDs and took genital swabs from male and female patients, which were analyzed with polymerase chain reaction for the presence of HPV-DNA. Clinical and laboratory data was collected to identify risk factors. Results 28 PID patients were included in this study. 10 of 28 (35.7%) had HPV-DNA in their genital swabs. 6 patients had high-risk HPV-types (21.4%). Most patients had asymptomatic HPV-infections, as genital warts were rare (2 of 28 patients) and HPV-associated malignancy was absent. Differences in the HPV-positivity regarding clinical PID-diagnosis, duration of PID, age, sex, immunosuppression, immunoglobulin replacement, or circumcision in males were not present. HPV-positive PID patients had higher numbers of T cells (CD3+), of cytotoxic T cells (CD3+/CD8+), of transitional B cells (CD19+/CD38++/CD10+/IgD+), and of plasmablasts (CD19+/CD38+/CD27++/IgD-) compared to HPV-negative. Conclusion PID patients exhibit a high rate of genital HPV-infections with a high rate of high-risk HPV-types. Regular screening for symptomatic genital HPV-infection and HPV-associated malignancy in PID patients seems recommendable.

Abstract
This study evaluated the effectiveness of the community-based organization (CBO)-private clinic service model in increasing human papillomavirus (HPV) vaccination uptake among unvaccinated men who have sex with men (MSM) in Hong Kong during a 12-month follow-up period. A CBO-private clinic model was implemented to promote HPV vaccination among Chinese MSM. A CBO with good access to MSM approached MSM aged 18–45 years who had never received an HPV vaccination, invited them to receive an online health promotion, and referred them to receive HPV vaccination at gay-friendly private clinics. A baseline survey and a follow-up evaluation at Month 12 were conducted. A total of 350 participants completed the baseline survey. Among 274 participants who were followed up at Month 12, 46 (16.8%) had taken up at least one dose of HPV vaccination. After adjusting for significant baseline characteristics, the perceived susceptibility (AOR:1.25, p = 0.002) and perceived severity (AOR:1.21, p = 0.003) of HPV and HPV-related diseases, perceived benefits (AOR:1.16, p = 0.03), self-efficacy to receive HPV vaccination (AOR:1.37, p = 0.001), and behavioral intention to take up HPV vaccination at baseline (AOR:6.99, p < 0.001) significantly predicted HPV vaccination uptake. The process evaluation of the program was positive. The CBO-private clinic service model was helpful in increasing HPV vaccination uptake among MSM.

Abstract
OBJECTIVE Most evidence, including recent randomized controlled trials, analysing anal squamous cell carcinoma (SCC) do not consider immunocompromise patient population. The aim of this study was to compare clinical and oncological outcomes among immunocompetent and immunocompromised patients with anal squamous cell carcinoma. METHOD Multicentric retrospective comparative study including 2 cohorts of consecutive patients, immunocompetent and immunocompromised, diagnosed with anal SCC. This study evaluated clinical characteristics, clinical response to radical chemoradiotherapy (CRT) and long-term oncological results including both local and distant recurrence, overall survival (OS) and disease-free survival (DFS). RESULTS A total of 84 patients, 47 (55.6%) female, diagnosed with anal SCC from January 2012 to December 2017 were included, 22 (26%) and 62 (74%) patients in immunocompromised and immunocompetent groups respectively. Patients in immunocompromised group were significantly younger (53 vs. 61 years; P=0.001), with smaller tumoral size (P=0.044) and reported higher rates of substance abuse. including tobacco use (P=0.034) and parenteral drug consumption (P=0.001). No differences were found in administered therapies (P=301) neither in clinical response to chemoradiotherapy (83 vs. 100%). Moreover, similar 5-year OS (60 vs. 64%; P=0.756) and DFS (65 vs. 68%; P=0.338) were observed. CONCLUSION The present study shows no significant differences in long-term oncological results among immunocompetent and immunocompromised patients diagnosed with anal SCC, with a similar oncologic treatment. This evidence might be explained due to the close monitoring and adequate therapeutic control of HIV positive patients.

Abstract
Regular tests for human papillomavirus (HPV) and early treatment could represent an important strategy for preventing anal cancers among men who have sex with men (MSM). This study investigated facilitators and barriers to take up clinician-collected and self-collected HPV tests among Chinese MSM. This study was based on the baseline sample of a longitudinal study promoting HPV vaccination among 350 Chinese MSM who had never received an HPV vaccination. The baseline survey was conducted from August 2019 to April 2020. The prevalence of any HPV tests uptake in lifetime was 19.1%; 4.9% had HPV infection in anus, genital, oral cavity, and other places. Among the participants, 20% and 76.8% intended to take up self-financed and free clinician-collected HPV tests, and 76.8% intended to use free self-collected HPV tests. After adjusting for significant background characteristics, perceived risk of HPV infection, and perceived benefits, barriers, cue to action, and self-efficacy related to HPV tests in general and/or specific to self-collected HPV tests were associated with behavioral intention to take up free clinician-collected and/or self-collected HPV tests. Less than 20% of Chinese MSM reported HPV tests uptake. Modifying perceptions related to HPV tests may be useful to increase HPV tests coverage in this group.

Abstract
Background Human papillomavirus (HPV) vaccination is effective in the prevention of vaccine-type genital warts and cancers among men who have sex with men (MSM). Objective The primary objective of this randomized controlled trial (RCT) is to evaluate the efficacies of 2 web- and theory–based interventions with and without brief motivational interviewing (MI) over the phone to increase the completion of HPV vaccination among unvaccinated participants within a 24-month follow-up period compared with the control group. Methods A 3-arm parallel-group RCT was conducted between July 2017 and December 2019. Five telephone surveys were conducted at baseline and at 3, 6, 9, and 24 months by blinded interviewers. Participants were Hong Kong Chinese–speaking MSM aged between 18 and 45 years with regular internet access who were recruited from outreaching at venues, web-based recruitment, and peer referral. Those who had ever received HPV vaccination were excluded. A total of 624 participants were randomized into either the online tutorial (OT) only group (n=208), the OT plus MI group (OT-MI; n=208), or the control group (n=208). In total, 459 (459/624, 73.6%) completed the follow-up evaluation at 24 months. Participants in the OT group received a fully automated OT developed based on the health belief model. On top of the same OT, the OT-MI group received brief MI over the phone. Reminders were sent to the participants of the OT and OT-MI groups after 1, 2, 4, 6, and 8 months. Participants in the control group received web-based health communication messages unrelated to HPV or HPV vaccination. The research team validated the self-reported HPV vaccination uptake. Intention-to-treat analysis was used for outcome analyses. Logistic regression models and multivariable linear regression models were used to test the between-group differences in primary and secondary outcomes. Baron and Kenny’s methods were used to test the mediation hypothesis. Results The participants in the OT-MI group reported a significantly higher validated completion of HPV vaccination at 24 months than the control group (36/208, 17.3% vs 15/208, 7.2%; P=.006). However, the difference in HPV vaccination completion between the OT and the control groups (24/208, 11.5% vs 15/208, 7.2%; P=.17), or between OT-MI and OT groups (P=.13), was not statistically significant. The association between randomization status (OT-MI group vs control group) and HPV vaccination completion became statistically nonsignificant after controlling for changes in the perceived susceptibility to HPV (24 months vs baseline), whereas perceived susceptibility remained strongly associated with HPV vaccination uptake in the model (P<.001). Changes in perceived susceptibility fully mediated the intervention effect. Conclusions Theory-based OT with brief MI over the phone was effective in increasing HPV vaccination completion among Chinese MSM. Perceived susceptibility is an active theoretical component that causes behavioral changes. Trial Registration ClinicalTrials.gov NCT03286907; https://clinicaltrials.gov/ct2/show/NCT03286907

Abstract
High-risk human papillomavirus strains are widely known to be the causative agents responsible for cervical cancer development. Aggregated damage caused by papillomaviruses solely is estimated in at least 5% of all malignancies of the human body and 16% in cancers that affect the female genital area. Enhanced understanding of the complex issue on how the high extent of carcinogenicity is eventually formed due to the infection by the Papoviridae family would contribute to enhancing current prevention strategies not only towards cervical cancer, but also other HPV associated cancers. This review article is aimed at presenting the key points in two directions: the current cervical cancer prevention and related aspects of HPV behavior. Virtually all applied technologies related to HPV diagnostics and screening programs, such as HPV tests, colposcopy-based tests (VIA/VILI), conventional and liquid-based cytology, currently available are presented. Issues of availability, advantages, and drawbacks of the screening programs, as well as vaccination strategies, are also reviewed in the article based on the analyzed sources. The current point of view regarding HPV is discussed with emphasis on the most problematic aspect of the HPV family concerning the observed increasing number of highly carcinogenic types. Present trends in HPV infection diagnostics throughout the human fluids and tissues are also reported, including the latest novelties in this field, such as HPV assay/self-sample device combinations. Besides, a brief outline of the related prevention issues in Kazakhstan, the leading country of Central Asia, is presented. Kazakhstan, as one of the post-soviet middle-income countries, may serve as an example of the current situation in those terrains, concerning the implementation of globally accepted cervical cancer prevention strategies. Along with positive achievements, such as the development of a nationwide screening program, a range of drawbacks is also analyzed and discussed.

Abstract
The male genital tract (MGT) is the target of a number of viral infections that can have deleterious consequences at the individual, offspring, and population levels. These consequences include infertility, cancers of male organs, transmission to the embryo/fetal development abnormalities, and sexual dissemination of major viral pathogens such as human immunodeficiency virus (HIV) and hepatitis B virus. Lately, two emerging viruses, Zika and Ebola, have additionally revealed that the human MGT can constitute a reservoir for viruses cleared from peripheral circulation by the immune system, leading to their sexual transmission by cured men. This represents a concern for future epidemics and further underlines the need for a better understanding of the interplay between viruses and the MGT. We review here how viruses, from ancient viruses that integrated the germline during evolution through old viruses (e.g., papillomaviruses originating from Neanderthals) and more modern sexually transmitted infections (e.g., simian zoonotic HIV) to emerging viruses (e.g., Ebola and Zika) take advantage of genital tract colonization for horizontal dissemination, viral persistence, vertical transmission, and endogenization. The MGT immune responses to viruses and the impact of these infections are discussed. We summarize the latest data regarding the sources of viruses in semen and the complex role of this body fluid in sexual transmission. Finally, we introduce key animal findings that are relevant for our understanding of viral infection and persistence in the human MGT and suggest future research directions.

Abstract
Men who have sex with men (MSM) are recommended to take up human papillomavirus (HPV) vaccination. There are concerns that MSM would increase sexual risk behaviors after taking up HPV vaccination, a phenomenon known as risk compensation. This study investigated the prevalence of and factors associated with behavioral intention to reduce the frequency of condom use with men after receiving the HPV vaccination. The study was based on the baseline sample of an ongoing randomized controlled trial promoting HPV vaccination among MSM in Hong Kong. Hong Kong Chinese-speaking MSM who have never vaccinated against HPV were recruited from multiple sources. A total of 624 participants completed the baseline survey during July to December 2017. The prevalence of behavior intention to reduce the frequency of condom use with regular and non-regular male sex partners after receiving HPV vaccination was 6.9% and 4.0%; 8.0% of them intended to reduce condom use with either type of male partners after receiving the HPV vaccination. Adjusting for significant background variables (education level and condomless anal intercourse with men in the last six months), two constructs of the pre-intentional phase of Health Action Process Approach model were significantly associated with the dependent variable in the expected direction. They were (1) positive outcome expectancies of condomless anal intercourse after receiving HPV vaccination (adjusted odds ratios [AOR]: 1.29, 95% confidence interval [CI]: 1.12, 1.48, p < 0.001) and (2) perceived self-efficacy of consistent condom use after receiving HPV vaccination (AOR: 0.83, 95% CI: 0.70, 0.92, p = 0.001). Risk compensation may not be a major concern when promoting HPV vaccination among MSM. The results should be assuring health-care providers and policymakers.

Abstract
The aim of this study was to determine the risk factors, genotype-specific prevalence, and concordance of human papillomavirus (HPV) infections at three anatomical sites in a cohort of high-risk Greek men. Patients were recruited from sexually transmitted infection and HIV clinics in Athens. Samples were obtained from oral, penile, and anal sites of 294 study participants and HPV testing was performed on 882 samples using next-generation sequencing. Patients also completed a questionnaire assessing risk factors for infection. The mean age of the participants was 33.1, 30% identified as men who have sex with men (MSM), and 21% were HIV positive. The prevalence of HPV was 49%; it was the highest at anal sites (33%) compared with 23% at penile sites (P=0.008) and 4% at oral sites (P<0.001). The most common HPV types in order of frequency were 6, 44, 16, 53, and 89. The genotype concordance rate was the highest between the penile and anal sites (7%), followed by 2% for anal-oral concordance. Identifying as MSM [adjusted odds ratios (aOR)=6.75, P<0.001] and being HIV positive (aOR=2.89, P=0.026) were significant risk factors for anal HPV infection, whereas alcohol use (aOR=0.45, P=0.002) was associated negatively with infection. The only significant risk factor for oral infection was an older age of sexual debut (aOR=1.32, P=0.038). Nearly half of our study participants tested positive in at least one of three anatomical sites. Using next-generation sequencing, we could identify high-risk types that are not covered by the current vaccine and would be missed by traditional HPV testing kits.

Abstract
We systematically reviewed the literature on anal, penile, cervical, and oropharyngeal human papillomavirus (HPV) infection in Greece to provide a comprehensive overview of HPV prevalence and to explore the reporting of HPV in Greek men and women. A total of five databases, including PubMed and Scopus, were searched up until 1 January 2015 for studies looking at HPV prevalence, incidence, or risk factors by anatomical site. We identified 50 eligible studies for inclusion. The majority of them were cervical studies (n=26) followed by head and neck studies (n=13) with only two studies exclusively focusing on anal sites and two on penile sites. The remaining studies examined prevalence from multiple sites. Most studies looked at small, high-risk populations, and HPV prevalence ranged from 2.5-43.4% for cervical studies; 0-91% for head and neck studies; 54.6-78.4% for anal studies; and 20.3-66.7% for penile studies. Age, smoking, and number of sexual partners were the commonly assessed risk factors. There were significant sex and anatomic site disparities in the reporting of HPV prevalence. Given the relationship between HPV infection and the increasing incidence of anal cancer in men, more research is needed to reveal the prevalence of HPV at these sites in Greek men, especially given the reports of the declining health of the Greek population.

Abstract
Background High risk human papillomavirus (HR-HPV) infection in males is a health issue with implications for HPV-related lesions in their partners. The identification of risk factors for male infection may improve our understanding of HR-HPV transmission and prevention. The aim of this study was to evaluate the relationships between lifestyle, genital warts and HR-HPV infection. The study was focused on men with an increased risk of HR-HPV infection: male sexual partners of women diagnosed with high-grade squamous intraepithelial cervical lesions. Methods Men were enrolled and prospectively recruited within the first six months after diagnosis of cervical lesions in their female partners (n = 175, 2013–2016). Epidemiological and sexual behaviour data were obtained. The presence of genital warts was established by visual inspection. Detection and genotyping of HR-HPV infection in genital samples were performed with a Linear Array HPV Genotyping Test. All HR-HPV positive men were offered a follow-up exam at 12 months. SPSS version 19 was used for statistical analysis. Results and discussion The prevalence of HR-HPV infection in men was 45.1% (79/175). Genital warts were observed in 10.3% (18/175) of the subjects. Detection of genital warts (OR 3.5, p = 0.015), smoking habits (OR 2.3, p = 0.006) and sexual debut before 16 years old (OR 2, p = 0.035) were associated with an increased risk for HR-HPV infection (univariate analysis). This association was also observed for genital warts and smoking status in a multivariate analysis. The same genotype was found after one year in 71.4% (20/28) of subjects. Conclusions The presence of genital warts and smoking habits seem to be associated with a higher risk of HR-HPV infection in males. Earlier sexual debut may increase this risk. Extensive knowledge of the natural history of HR-HPV infection in males is an absolute requirement for the design and implementation of prevention strategies for the general population as well as for specific populations such as couples after treatment for high-grade cervical lesions.

Abstract
Human papillomavirus (HPV) has been identified as etiologic agent of various cancers for both men and women. However, HPV vaccine has not been recommended for men in China by far. To provide more evidences to promote HPV vaccination among males at high-risk of infection, this study investigated genital HPV genotypes among male attendees of sexually transmitted disease (STD) clinic. Male attendees (⩾18 years old) were recruited from STD clinic of Beijing Ditan Hospital. Data on sociodemographic characteristics and self-reported sexual behaviors were collected based on questionnaire. Genital swab specimens were collected for HPV genotypes. Finally, a total of 198 eligible participants were included in the study. Nearly half of them were infected with at least one type of HPV. The prevalence of genital infection among participants with only heterosexual behaviors (50·91%, 56/110) was significantly higher than those with only homosexual behaviors (36·36%, 32/88) (P < 0·001). However, the distribution pattern of the most frequently observed HPV subtypes were found to be similar between these two subgroups. HPV31, HPV18, HPV16 and HPV58 were the most frequently identified high-risk types and HPV11, HPV6, HPV81 and HPV61 were the most frequently observed low-risk types. Our results, although need further verification by larger sample size, suggested that currently available HPV vaccines covered most prevalent HPV types observed in Chinese men. As HPV vaccine has been approved for application in females in China, molecular epidemiological studies and intervention studies among high-risk males should be promoted as well.

Abstract
We conducted a cross-sectional study on the occurrence of a specific type of genital human papillomavirus (HPV) among long-term monogamous male partners of women with cervical dysplasia and genital warts. The purpose of the study was to improve knowledge with regards to the management of these couples. The presence of genital HPV-DNA was detected by PCR with broad spectrum primers followed by hybridization. 82 males met the study criteria, 41 in each group. Genital HPV-DNA prevalence was 67.5% in the genital warts group and 72.2% in the cervical dysplasia group. The prevalence of high risk HPVs was higher in the cervical dysplasia group, while low risk HPVs were more prevalent in the genital warts group (p < .05). The prevalence of HPV in males was independent of the duration of the relationship (73.5% for 6-24 months and 66.7% for longer relationships). In conclusion, our results suggest that the prevalence of the genital HPV infection in both groups of male partners is comparable and very high, but the spectrum of HPV types varies significantly. The presence of the genital HPV infection in male sexual partners seems to be independent of the duration of the relationship. Applying the HPV vaccination to boys may prevent this phenomenon.

Abstract
BACKGROUND It is crucial to understand the epidemiology and natural history of human papillomavirus (HPV) infection in both men and women, to prevent the increasing HPV-related disease burden in men. Data on HPV prevalence among men in the general population are limited. In this cross-sectional population-based study, we aimed to estimate genital HPV infection prevalence in Danish men using 2 different test methods. METHODS Penile swab samples from 2460 male employees and conscripts at military barracks in Denmark were tested for HPV DNA with the hybrid capture 2 (HC2) method, and a polymerase chain reaction (PCR) assay, Inno-LiPA. The overall and age- and type-specific prevalence of HPV infection with 95% confidence intervals (CIs) were estimated, and the correlation between the 2 assays was assessed. RESULTS The overall HPV prevalence was 22.2% (95% CI, 20.6-23.9) in the HC2 test and 41.8% (95% CI, 39.9-43.8) with PCR. Of the PCR-positive samples, 50.9% were negative in the HC2 test. Of 183 PCR-positive samples that could not be genotyped (HPVX), 88.0% (95% CI, 83.2-92.7) were HC2 negative. The most prevalent types were HPV-51, HPV-16, HPV-66, HPV-53, and HPV-6. The prevalence of high-risk and low-risk HPV peaked among men aged 20 to 29 years, whereas the HPVX prevalence increased with age. CONCLUSIONS Human papillomavirus is highly prevalent in the general male population of Denmark, with HPV-16 and HPV-51 being the most prevalent. Polymerase chain reaction detects twice as many positive samples as HC2 but includes HPVX, possibly representing cutaneous HPV types found on normal genital skin.

Abstract
This study assessed knowledge and attitudes about Human papillomavirus (HPV) and the relative vaccination and their determinants in a sample of young males. The survey was conducted between January and April 2015 among a sample of 1000 males aged between 14-24 y in the geographic area of Naples and Caserta, Italy. The 54.9% of the participants reported of having heard about the HPV infection. Those who were aware about the availability of the vaccine, who reported the first vaginal sexual encounter before the 18 y and at least at 18 y compared to those who had not had a complete sexual intercourse, who had undergone a health checkup in the last year, and who had received information about the HPV vaccine by physicians had a significant higher knowledge about the HPV infection. The 58.2% reported that they would be willing to receive the HPV vaccine. Those younger, who reported the first vaginal sexual encounter at least at 18 y, who agreed that male should receive the vaccine, who knew that both males and females can acquire the infection, and who agreed that the vaccine is an important preventive intervention, expressed more positive attitude toward willingness to receive the vaccine. More information about the HPV vaccine were required by those who agreed that the vaccine is an important preventive intervention, who reported the first vaginal sexual encounter at least at 18 y, who have had only one partner in the last year compared to students who had no partner, and who had received information about the vaccine by physicians. This study highlights a need for improved education of young males of the HPV infection and the associated diseases and about the benefit of the vaccination.

Abstract
BACKGROUND Little is known about the characteristics of high-risk papillomavirus (HR-HPV) infection in men. The aims of this cross-sectional study were: (a) to investigate HR-HPV prevalence and genotype distribution in men, sexual partners of women presenting with high-grade cervical intraepithelial neoplasia (HG-CIN), according to epidemiological characteristics, and (b) to assess type-specific concordance between partners. METHODS A total of 125 men were recruited within the first 6 months after HG-CIN diagnosis of their partner. Samples from the coronal sulcus, glans penis shaft, and scrotum were tested with linear array HPV genotyping assay (Roche Diagnostics, Mannheim, Germany). Type-specific concordance within 120 couples was studied. Epidemiological factors were evaluated by multivariate logistic regression analysis. SPSS 19 (IBM, Chicago, USA). RESULTS The prevalence of HR-HPV infection in males was 50.4% (63/125). HPV16/53/52/51/66/31 were the most frequent genotypes (24/10.4/9.6/8.8/8/7.2%, respectively). Current smoking was associated with an increased risk for HR-HPV infection in men (38.2% (21/55) vs 60% (42/70), OR 2.4, p=0.025). Among 60 infected couples, 62% shared at least one genotype: 41.7% couples were concordantly HPV16 positive and 18.3% were HPV16 negative (kappa value: 0.21). The proportion of women with the same genotype as their male partner was higher than the proportion of men sharing the same genotype as their female partner: 58.7% (37/63) vs 30.8% (37/120), p<0.0001. CONCLUSIONS Sexual partners of women with HG-CIN are a significant reservoir and vector of HPV infection, a fact that could contribute to making viral clearance more difficult to achieve in their partners after treatment of their HG-CIN lesions.

Abstract
Two males presented to our urology department with complaints of bleeding and malodor from buried phallus within a suprapubic fat pad. Although both men had neonatal circumcisions, advanced penile carcinoma was found in both men. Formal penectomies showed high grade, poorly differentiated squamous cell carcinoma invading the corporal bodies and urethra. Buried penis represents a difficulty in early detection of suspicious lesions but may also provide an environment susceptible to poor hygiene and subsequent chronic inflammation. Patients with buried penis may be at a higher risk for development of invasive penile cancer and may benefit from regular and thorough genital exams.

Abstract
ABSTRACT The quadrivalent HPV vaccine (HPV4) is safe and highly efficacious, and can significantly reduce the burden of HPV-related genital warts and cancers among men, in addition to promoting herd immunity. Nevertheless, HPV4 coverage among boys remains low in most settings. Research to date has focused predominantly on HPV vaccination of girls to prevent cervical cancer. Most countries with publicly funded healthcare where HPV4 is licensed cover the costs of HPV vaccination programs for girls only. We critically review the evidence for extending publicly funded HPV vaccination programs to boys in addition to girls. After an overview of research on HPV prevalence and associated cancers among men, we review cost–effectiveness studies, benefits of universal versus targeted vaccination approaches and multifaceted health equity concerns, along with directions in vaccine delivery programs and intervention research to promote HPV vaccine uptake for boys. Comprehensive evaluation of the systematic exclusion of boys from publicly financed HPV vaccination programs is warranted given tremendous public health implications of new infections and subsequent cancers that could have otherwise been averted.
