SUMMARYHuman 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.

AbstractMen who have sex with men (MSM) are disproportionately affected by anal cancer, predominantly caused by high-risk (HR) human papillomavirus (HPV) infection. Currently, the nonavalent HPV vaccine provides coverage against nine HPV genotypes, including seven HR-HPV genotypes. Here, we characterize anal HR-HPV genotype distribution and associated risk factors in MSM from Toronto, Canada recruited between September 2010 and June 2012. Wilcoxon–Mann–Whitney test was used for continuous variables, Chi-square test was performed for categorical variables, and a multivariable model using logistic regression was created to assess for correlates of anal HR-HPV infection. A total of 442 MSM were recruited, with a median age of 45 (IQR 38–50) and an overall HPV prevalence of 82%. The prevalence of any HR-HPV infection was 65.3% and 50.7% in the HIV-positive and HIV-negative MSM, respectively. No participant tested positive for all genotypes covered by the nonavalent vaccine. HIV status (aOR 1.806; 95% CI 1.159–2.816), smoking (aOR 2.176; 95% CI 1.285–3.685) and the number of lifetime sexual partners (aOR 2.466; 95% CI 1.092–5.567) were independent risk factors for anal HR-HPV infection. Our findings will be useful to inform HPV vaccine rollout and HPV prevention strategies in Canadian MSM.

Behavioural Characteristics

Two-hundred undergraduate students completed an anonymous questionnaire after viewing a human papillomavirus (HPV) vaccine television commercial. Eight-four percent of participants would accept a free HPV vaccine, whereas 47% were unconcerned about future personal HPV infection risk. Males were less likely to accept a free HPV vaccine and to be concerned about future personal HPV infection risk. Perceived HPV vaccine effectiveness was significantly greater among participants who had previously heard of the vaccine and who knew that HPV is sexually transmitted. More education on the role of sexual behavioural characteristics of both males and females in HPV transmission is necessary to promote awareness and concern of personal HPV infection risk and acceptance of HPV vaccination.

Control And Prevention

Human papillomavirus (HPV) remains the most common sexually transmitted infection with a lifetime incidence of over 75%. Based on US data from the Centers for Disease Control and Prevention (CDC), 64% of invasive HPV-associated cancers are attributable to HPV 16 or 18 (65% for females; 63% males) and may be prevented by vaccination with either the quadrivalent or nonavalent HPV vaccine. Public HPV vaccination programs are now the norm for women aged 9-45 years and men aged 9-26 years in Canada. Yet, only recently have guidelines begun to consider vaccination of men older than 26 years of age. There now exist compelling reasons to recommend vaccination against HPV amongst males >26 years of age. Recognizing that the risks posed by HPV infection persist beyond 26 years of age, that the vaccination of men aged 26-45 years with HPV vaccine confers immunogenicity at levels demonstrably efficacious against HPV-related diseases, and that the Food and Drug Administration recently expanded the HPV vaccination to include older men, it is argued that HPV vaccination in men older than 26 years of age should be routinely recommended.

e13566 Background: Human papilloma virus (HPV) is the most common sexually transmitted agent and has extensive association with many malignancies such as cervical, vaginal, vulvar, penile, and head and neck cancers. Vaccination helps prevent sexually transmitted diseases due to HPV. In addition, it provides protection against cancers caused by persistent, high-risk HPV infection in both male and female. Methods: Data collected from the medical records of patients diagnosed with anogenital, and head and neck cancers during 2017-2019 were studied retrospectively and the association of HPV infection was analyzed. Results: There were thirty-three cases of anogenital, and head and neck cancers diagnosed during the study period. The following were the occurrences: penile cancer 1, anal cancer 4, cervical/uterine/vaginal cancers 10, and head and neck cancer including tonsil, base of tongue, vocal cord, and glottis 18. HPV status was available in twenty-six (79%) patients. Fourteen patients were positive for high-risk 16/18 HPV strain, twelve were HPV negative, and HPV status was unknown for seven patients. Most of the patients were smokers and none of them had received HPV vaccination. The patients were treated appropriately with chemotherapy, radiation, and surgery. Conclusions: Human papilloma virus (HPV) infection type 16/18 is the most common sexually transmitted infection associated with significant anogenital and head and neck cancers.Vaccinations protect against persistent, high-risk HPV infection that may lead to malignancies. However, the HPV vaccination initiation and completion rates are only 41.7% and 21.6% respectively in males, and 60% and 39.7% respectively in females. The lack of opportunity does not appear to be a major reason for this low coverage. Some of the barriers for low adoption of HPV vaccination were concern about vaccine safety (70%), lack of knowledge about HPV related diseases (56%), very young to vaccinate (56%), fear of riskier sexual behavior (56%), and reluctance as not being included in the required immunization schedule (71%). In addition, several people refused HPV vaccination due to misinformation in social media. The primary purpose of HPV vaccination is to help prevent sexually transmitted diseases. Further, such vaccination can also prevent several cancers caused by persistent infection. Therefore, HPV vaccination has the potential to eliminate such risk if enforced at a young age in school. The above study and data stress this role and the importance of public awareness of the HPV vaccine as a cancer prevention agent.

Abstract Background Anorectal high-risk human papillomavirus (hr-HPV) infection is associated with anal malignancies. However, the epidemiological data is quite limited in Japan. Methods Anorectal swab was obtained from HIV-infected and –uninfected men who have sex with men (MSM). Only high-risk HPV genotypes were examined by the Hybrid Capture-based methodology. Anal cytology was determined by the modification of the Bethesda System classification. Results In total, 644 participants were included. No participant had history of HPV vaccination at inclusion. The overall prevalence of hr-HPV was 58.5% (95% confidence interval: 54.7-62.3). The most frequently detected hr-HPV genotypes in order were HPV-52, -16, and -58. Among the HPV infected subjects, 82.8% (312/377) were infected with at least one of the 9 valent vaccine covered genotypes. Incidence of abnormal cytology was positively correlated with the number of HPV genotypes infected rather than the difference in genotypes. Multivariate analysis identified the number of detected hr-HPV genotypes as well as HIV-infection were the independent risk factors for pre-cancer. Conclusion Nine valent vaccine preventable HPVs are currently prevalent among MSM in Japan. Also, increased numbers of hr-HPV genotypes were strongly associated with anorectal pre-cancer. Universal HPV vaccination should be considered for Japanese MSM.

Abstract Background Whether type-specific human papillomavirus (HPV) infection influences the risk of acquiring infections with other HPV types is unclear. We studied concurrent HPV infections in 17-year-old girls from 2 birth cohorts; the first vaccine-eligible cohort in Norway and a prevaccination cohort. Methods Urine samples were collected and tested for 37 HPV genotypes. This study was restricted to unvaccinated girls from the prevaccination cohort (n = 5245) and vaccinated girls from the vaccine-eligible cohort (n = 4904). Risk of HPV infection was modelled using mixed-effect logistic regression. Expected frequencies of concurrent infection with each pairwise combination of the vaccine types and high-risk types (6/11/16/18/31/33/35/39/45/51/52/56/58/59) were compared to observed frequencies. Results Infection with multiple HPV types was more common among unvaccinated girls than vaccinated girls (9.2% vs 3.7%). HPV33 and HPV51 was the only HPV pair that was detected together more often than expected among both unvaccinated (P = .002) and vaccinated girls (P &lt; .001). No HPV pairs were observed significantly less often than expected. Conclusions HPV33 and HPV51 tended to be involved in coinfection among both unvaccinated and vaccinated girls. The introduction of HPV vaccination does not seem to have had an effect on the tendency of specific HPV types to cluster together.

Papillomavirus Infection

Human papillomavirus, or HPV, is a common sexually transmitted disease, most often acquired during the adolescence or the early 20s. It can be divided into oncogenic and nononcogenic serotypes. It is responsible for genital warts as well as pathologic diseases that can lead to genital cancers and cancers of the oropharyngeal tract in both males and females. The majority of adolescents who acquire HPV infections do not go on to develop cancer. New discoveries about the virus’ persistence and latency direct how we treat adolescents with HPV infections. Recommendations for prevention of HPV include use of the 9-valent vaccine against the most common oncogenic HPV serotypes. Screening should be delayed until the age of 21, with the exception of immunocompromised women. The HPV vaccination is safe and effective, and does not encourage sexual activity among adolescents. Both boys and girls should be vaccinated against HPV at 11 to 12 years of age but may receive the vaccination as early as 9 or as late as 21 (males) or 26 (females) years of age. The vaccine may now also be given in only two doses if the series was started before the age of 15. Follow-up studies in the years after the vaccine’s introduction have shown large decreases in HPV infection rates.

Background: Cervical cancer is the second leading cause of death in india. it is also one of the few malignancies where an infectious etiological agent human papilloma virus (HPV) has been identified. With the advent of HPV vaccination, it is possible to reduce the morbidity and mortality associated with carcinoma cervix. But biggest hurdle to achieve this is the lack of awareness about the availability and use of HPV vaccine. This study was conducted to know knowledge and awareness of HPV infection and vaccination among medical and paramedical students. We also evaluated the acceptability and coverage of HPV vaccine among these students.Methods: This study was conducted among a total of 520 female students of the Sri Dharmasthala Manjunatheshwara University with the help of a questionnaire. The study group included 207 MBBS students, 167 BDS students, 89 nursing students and 57 physiotherapy students.Results: Most of the students were in 18-20 years’ age group. Nearly 40.57% of the students knew that HPV is sexually transmitted and 29.80% were aware that this infection can be prevented. Availability of HPV vaccine was known to 75% of the students and the main source of their information was through their college teachings. Nearly 43.75% of the students knew HPV vaccine protects against cervical cancer and 26.73% of the students were vaccinated. Overall knowledge and awareness were better among medical students.Conclusions: A lot of work needs to be done so as to make the target population accept HPV vaccine. There is a great difference between awareness of availability of the vaccine and its use. This emphasizes the need for health care professionals to take special interest in promoting this vaccine in the general population.
