Abstract
Oral HPV infection is the main risk factor for the development of oropharyngeal carcinoma. Men who have sex with men (MSM), especially if living with HIV (PLWH), are at increased risk of infection and consequently of cancer development. Aim of this study is to evaluate the impact of nonavalent vaccine on oral HPV infection in a cohort of MSM and transgender women (TGW). This prospective study included all MSM and TGW who started nonavalent HPV vaccination from May 2019 to September 2021. Oral rinse was collected before each vaccine administration and after six months of follow up. Descriptive statistics were used. Kaplan Meier probability curves and Cox regression models for HPV acquisition and clearance were calculated. The analysis included 211 individuals (202 MSM and 9 TGW). PLWH were 138 (65.4%). Baseline oral rinse was positive in 30 subjects (14.2%). Positivity rate did not change over time (p = 0.742), even when restricting the analysis only to high-risk genotypes (p = 0.575) and to genotypes covered by vaccine (p = 0.894). The risk to acquire HPV infection was 12.8% at one year and 33.4% at two years after vaccination. The probability to clear the infection was 67.6% at one year and 87.9% at two years. HIV infection had no impact on vaccine efficacy. Age above 45 years was the only factor associated to HPV acquisition (aHR 4.06, 95% CI 1.03-15.98, p = 0.045). Prevalence of oral HPV infection was higher in PLWH, but HIV had no impact on viral clearance or acquisition after vaccination.

Abstract
This guideline offers recommendations on the diagnosis, treatment and health promotion principles needed for the effective management of human papillomavirus (HPV)-related warts at anogenital sites including the external genitals, vagina, cervix, urethra, perianus and anal canal. The guideline is aimed primarily at patients aged 16 years or older presenting to healthcare professionals working in level 3 sexual health services in the United Kingdom. However, the principles of the recommendations may be applied in other care settings, including in primary care, using locally adapted care pathways where appropriate. The management of HPV-related anogenital dysplasia or warts at other extragenital sites is outside the scope of this guideline.

Abstract
OBJECTIVES Anal condylomas are a manifestation of anal human papillomavirus infection and can be associated with precancerous lesions and squamous cell carcinomas. Several methods have been described for treatment, including argon plasma coagulation. A narrative review of the evidence published on this topic was conducted. METHODS A search was conducted using PubMed, Scopus, and Web of Science databases. RESULTS Five studies reported on anal/perianal condyloma treatment with argon plasma coagulation. In 3 of these studies, there was a comparison with other treatment methods (addition of imiquimod, electrofulguration, and electrocautery, respectively). Argon plasma coagulation settings varied between studies. This type of treatment was effective for ablation. Recurrence rates and follow-up times varied largely between studies. No major complications, such as pain, scarring, sexual dysfunction, or severe bleeding were described. CONCLUSION Studies indicate that argon plasma coagulation is an effective and safe therapy for anal and perianal condylomas.

Abstract
BACKGROUND We sought to summarize human papillomavirus (HPV) vaccine efficacy/effectiveness (VE) against anal HPV infection and anal intraepithelial neoplasia (AIN). METHODS We performed literature review and meta-analysis to estimate VE, stratified by age and analytic population (per-protocol efficacy [PPE] or intention-to-treat [ITT] population in clinical trials, or all participants in real-world studies). RESULTS We identified 6 clinical trials and 8 real-world studies. In participants vaccinated at age ≤26 years (mainly human immunodeficiency virus [HIV]-negative individuals), significant VE against incident/prevalent anal HPV infection was reported in clinical trials, with a higher estimate in PPE (2 studies with 2390 participants; VE, 84% [95% confidence interval (CI), 77%-90%]; I2 = 0%) than ITT (2 studies with 4885 participants; 55%, 39%-67%; I2 = 46%) populations or in real-world studies (4 studies with 2375 participants; 77%, 40%-91%; I2 = 81%). HPV vaccination at age ≤26 years was associated with significant VE in preventing persistent anal HPV infection and AIN. No significant VE against anal HPV infection or AIN was found in persons vaccinated at age >26 years (mainly people living with HIV). CONCLUSIONS There is strong evidence for high VE against anal HPV infection and AIN in HIV-negative individuals vaccinated at age ≤26 years. However, the lower impact in ITT than in PPE populations and the lack of significant effect in people living with HIV aged >26 years indicates that vaccines have the higher impact in populations with less sexual exposure to anal HPV.

Abstract
Individuals with human papillomavirus (HPV)-related disease remain at risk for subsequent HPV infection and related disease after treatment of specific lesions. Prophylactic HPV vaccines have shown benefits in preventing subsequent HPV-related disease when administered before or soon after treatment. Based on our understanding of the HPV life cycle and vaccine mechanism of action, prophylactic HPV vaccination is not expected to clear active persistent HPV infection or unresected HPV-associated dysplastic tissue remaining after surgery. However, vaccination may reasonably be expected to prevent new HPV infections caused by a different HPV type as well as re-infection with the same HPV type, whether from a new exposure to an infected partner or through autoinoculation from an adjacent or distant productively infected site. In this review, we describe the evidence for using prophylactic HPV vaccines in patients with HPV-associated disease before, during, or after treatment and discuss potential mechanisms by which individuals with HPV-associated disease may or may not benefit from prophylactic vaccines. We also consider how precise terminology relating to the use of prophylactic vaccines in this population is critical to avoid the incorrect implication that prophylactic vaccines have direct therapeutic potential, which would be counter to the vaccine's mechanism of action, as well as considered off-label. In other words, the observed effects occur through the known mechanism of action of prophylactic HPV vaccines, namely by preventing virus of the same or a different HPV type from infecting the patient after the procedure.

Abstract
OBJECTIVES Sexual gender minority (SGM) populations are at risk for human papillomavirus (HPV)-related cancers of the anogenital tract and oropharynx and often face barriers to health care. The goals of this document are to clarify language to provide inclusive care for SGM populations and to provide recommendations for screening and prevention of HPV-related cancers in SGM populations. MATERIALS AND METHODS An expert committee convened by the American Society for Colposcopy and Cervical Pathology performed a narrative review of the literature through February 2023. A comprehensive MEDLINE database search was performed for relevant studies. The literature review was divided into categories by organ/topic and by SGM population. Given the variability in available data for several of the categories, recommendations were made based on national guidelines where appropriate or expert opinion where there were less data to support risk-based guidelines. RESULTS Definitions and terminology relevant to SGM populations are presented. The authors advocate the adoption of sexual orientation gender identity data collection and an organ-based screening approach, which is possible with knowledge of patient anatomy, sexual behaviors, and clinical history. This includes screening for cervical cancer per national recommendations, as well as screening for anal, vulvar, vaginal, penile, and oral cancers based on risk factors and shared clinical decision making. The authors recommend consideration of HPV vaccination in all SGM individuals up to age 45 years old who are at risk. CONCLUSIONS An organ-based screening approach is part of a global strategy to create an inclusive care environment and mitigate barriers to screening and prevention of HPV-mediated cancers in SGM populations.

Abstract
BACKGROUND In 2009, Norway initiated routine quadrivalent HPV (qHPV) vaccination for girls at 12-13 years of age to protect against virus types causing cervical cancer, HPV16/18, and HPV6/11 which cause anogenital warts (AGW). We wanted to investigate qHPV vaccine effectiveness (VE) against AGW in females before and after first AGW episode and to assess the impact of female vaccination in males. MATERIALS AND METHODS QHPV vaccination and AGW episodes were collected for the time period 2006-2016 for birth cohorts 1975-2003. Cox models were applied to age at first, as well as at second AGW episode. Finally, we estimated the impact of the female vaccination program on unvaccinated males. RESULTS The VE against the first episode of AGW was strongly dependent on vaccination age, with hazard ratios (HRs) compared to unvaccinated individuals of 0.2, 0.2, 0.3, 0.5, 1.0, 1.3, and 2.7, for age groups of ⩽13, 14-15, 16-17, 18-19, 20-24, 25-29, and 30+ years at first vaccination, respectively. Among women who had suffered a first episode of AGW, subsequent qHPV vaccination did not protect against a second episode, with HRs of 0.8, 1.0, and 1.4, for age groups of ⩽17, 18-24, and 25+ years at first vaccination. A gradually decreasing AGW risk was seen in unvaccinated male cohorts neighboring the first routinely vaccinated female 1997 cohort. CONCLUSIONS When administered before 14 years of age, qHPV vaccination reduced the probability of AGW about fivefold. The effect decreased sharply with vaccination age, and was not significant among women vaccinated after age 20 years. QHPV administered after the first AGW episode did not protect against a second AGW episode. Herd effects were indicated in unvaccinated males, as we observed a gradual decrease in AGW rates from the 1993 male birth cohort and onwards.

Abstract
Human papillomavirus (HPV)-related diseases are highly prevalent in men worldwide, comprising external anogenital condyloma, anal intraepithelial neoplasia (AIN), penile intraepithelial neoplasia (PIN), and anogenital and oropharyngeal cancers. There is exceptionally low vaccine coverage in the male population. Only 4% of men were fully vaccinated, worldwide, as of 2019. The aim of this review is to assess the impact of HPV vaccination on male disease. Three databases (MEDLINE, Web of Science, Scopus) and Clinical Trials.gov were searched. We included thirteen studies, eight randomized controlled trials (RCTs), and five cohorts, comprising a total of 14,239 participants. Regarding anal disease, seven studies reported HPV vaccine efficacy ranging from 91.1% to 93.1% against AIN1, and ranging from 89.6% to 91.7% against AIN2|3 and anal cancer. Five studies showed an efficacy against genital condyloma of 89.9% in HPV-naïve males, varying between 66.7% and 67.2% in intention-to-treat populations. Studies reporting no efficacy have included older participants. These results support vaccination of young men previously infected, beyond HPV-naïve males. The evidence quality was moderate to low for most outcomes, namely genital diseases. RCTs are needed to assess the efficacy of HPV vaccination on male oropharyngeal cancer.

Abstract
BACKGROUND AND AIM Human papillomavirus (HPV) is sexually transmitted, one of the three most common sexually transmitted infections (STIs) in both males and females, and the most common viral STI. A crucial public health strategy to protect people against HPV is vaccination, which has shown its effectiveness in preventing HPV-related diseases. Presently, three types of vaccines are available (bivalent, quadrivalent, and nonvalent), and they all target the two most oncogenic virus genotypes (HPV 16 and 18). In recent years, the need to implement vaccination programmes that include all genders has been discussed in order to achieve herd immunity against HPV. To date, only a few countries have included young males in their vaccination programmes. Thus, our objective with this review is to provide an overview of the epidemiology of HPV and HPV prevention strategies and report the latest findings from the scientific literature.

Abstract
Specific adult populations known to be at high risk for human papillomavirus (HPV)-related disease, such as men who have sex with men, are inconsistently included in national immunization programs. No compilation of the evidence on the real-world impact and effectiveness of HPV vaccines across these populations exists. This systematic literature review identifies and synthesizes the evidence of the real-world impact and effectiveness of the quadrivalent and nonavalent HPV vaccines in high-risk populations: women with prior/current HPV-related anogenital disease, men who have sex with men, immunocompromised/immunosuppressed individuals, female sex workers, transgender and non-binary individuals, and patients with recurrent respiratory papillomatosis (RRP). The outcomes included anogenital precancers/cancers, head and neck cancers, genital warts, and RRP recurrence. From the 2216 records identified, 30 studies (25 effectiveness and 5 impact studies) were included in this systematic literature review. The results, quantity, and quality of these studies were highly variable. The evidence for effectiveness was of high quality only in women with prior/current cervical disease and in individuals with RRP, the most frequently studied populations. No studies of transgender/non-binary individuals or female sex workers were identified. The real-world evidence supports HPV vaccination among women with prior cervical disease and individuals with RRP. Significant real-world data gaps remain in these high-risk populations.

Abstract
Background: The uptake of human papillomavirus vaccines (HPVV) among men who have sex with men (MSM) remains unsatisfactory. Healthcare providers play a crucial role in improving HPVV acceptability and uptake among MSM. This scoping review aims to provide an overview of (1) the perceived role of healthcare providers by MSM, and (2) the knowledge, beliefs and practices of healthcare providers themselves in promoting HPVV uptake. Methods: A literature search was performed with PubMed and Scopus databases using a specific search string. The relevant original research articles on this topic were identified, and the major findings were charted and discussed. Results: The literature search identified 18 studies on the perceived role of healthcare providers by MSM, and 6 studies on the knowledge, beliefs and practices of healthcare providers in promoting HPVV uptake among MSM. Recommendations by healthcare providers and disclosure of sexual orientation were important positive predictors of higher HPVV acceptability and uptake. Sexual healthcare providers were more confident in delivering HPVV to MSM clients compared to primary practitioners. Conclusion: Recommendation from, and disclosure of sexual orientation to healthcare providers are important in promoting HPVV uptake among MSM. The competency of healthcare providers in delivering HPVV to MSM can be improved by having clearer guidelines, education campaigns and better incentives.

Abstract
BACKGROUND Anorectal condyloma is the representative venereal disease caused by human papilloma virus (HPV), which has more 180 subtypes. Although there are various known risk factors for recurrence, few studies have investigated the influence of HPV subtypes. OBJECTIVE We aimed to investigate the correlation between the recurrence of anorectal condyloma and HPV subtypes. METHODS We analyzed the clinical and histopathological information of 143 patients who underwent surgery for anorectal condyloma at the National Medical Center between March 2016 and September 2020. PCR analyses were performed to confirm the HPV subtype in 24 patients. RESULTS Recurrence was confirmed in 63 patients through outpatient follow-up over a median of 31.7 months (range: 0-56.2) after surgery. Recurrence was significantly associated with anorectal condyloma severity (p < 0.001), but there were no differences between the primary and recurrent groups, CD4-positive cell counts, or human immunodeficiency virus loads. The high-risk HPV subtype was associated with a high recurrence rate. Furthermore, the overall recurrence rate in anorectal condyloma patients was 44.1%. CONCLUSION These results suggest that recurrence of anorectal condyloma has a significant association with high-risk HPV subtypes. Therefore, it is necessary to check for recurrences during follow-up after surgery.

Abstract
INTRODUCTION Vaccine effectiveness and impact studies are typically observational, generating evidence after vaccine launch in a real-world setting. For human papillomavirus (HPV) vaccination studies, the variety of data sources and methods used is pronounced. Careful selection of study design, data capture and analytical methods can mitigate potential bias in such studies. AREAS COVERED We systematically reviewed the different study designs, methods, and data sources in published evidence (1/2007-3/2020), which assessed the quadrivalent HPV vaccine effectiveness and impact on cervical/cervicovaginal, anal, and oral HPV infections, anogenital warts, lesions in anus, cervix, oropharynx, penis, vagina or vulva, and recurrent respiratory papillomatosis. EXPERT OPINION The rapid growth in access to real-world data allows global monitoring of effects of different public health interventions, including HPV vaccination programs. But the use of data which are not collected or organized to support research also underscore a need to develop robust methodology that provides insight of vaccine effects and consequences of different health policy decisions. To achieve the WHO elimination goal, we foresee a growing need to evaluate HPV vaccination programs globally. A critical appraisal summary of methodology used will provide timely guidance to researchers who want to initiate research activities in various settings.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection, with 15 HPV types related to cervical, anal, oropharyngeal, penile, vulvar, and vaginal cancers. However, cervical cancer remains one of the most common cancers in women, especially in developing countries. Three HPV vaccines have been licensed: bivalent (Cervarix, GSK, Rixensart, Belgium), quadrivalent (Merck, Sharp & Dome (Merck & Co, Whitehouse Station, NJ, USA)), and nonavalent (Merck, Sharp & Dome (Merck & Co, Whitehouse Station, NJ, USA)). The current HPV vaccine recommendations apply to 9 years old and above through the age of 26 years and adults aged 27–45 years who might be at risk of new HPV infection and benefit from vaccination. The primary target population for HPV vaccination recommended by the WHO is girls aged 9–14 years, prior to their becoming sexually active, to undergo a two-dose schedule and girls ≥ 15 years of age, to undergo a three-dose schedule. Safety data for HPV vaccines have indicated that they are safe. The most common adverse side-effect was local symptoms. HPV vaccines are highly immunogenic. The efficacy and effectiveness of vaccines has been remarkably high among young women who were HPV seronegative before vaccination. Vaccine efficacy was lower among women regardless of HPV DNA when vaccinated and among adult women. Comparisons of the efficacy of bivalent, quadrivalent, and nonavalent vaccines against HPV 16/18 showed that they are similar. However, the nonavalent vaccine can provide additional protection against HPV 31/33/45/52/58. In a real-world setting, the notable decrease of HPV 6/11/16/18 among vaccinated women compared with unvaccinated women shows the vaccine to be highly effective. Moreover, the direct effect of the nonavalent vaccine with the cross-protection of bivalent and quadrivalent vaccines results in the reduction of HPV 6/11/16/18/31/33/45/52/58. HPV vaccination has been shown to provide herd protection as well. Two-dose HPV vaccine schedules showed no difference in seroconversion from three-dose schedules. However, the use of a single-dose HPV vaccination schedule remains controversial. For males, the quadrivalent HPV vaccine possibly reduces the incidence of external genital lesions and persistent infection with HPV 6/11/16/18. Evidence regarding the efficacy and risk of HPV vaccination and HIV infection remains limited. HPV vaccination has been shown to be highly effective against oral HPV type 16/18 infection, with a significant percentage of participants developing IgG antibodies in the oral fluid post vaccination. However, the vaccines’ effectiveness in reducing the incidence of and mortality rates from HPV-related head and neck cancers should be observed in the long term. In anal infections and anal intraepithelial neoplasia, the vaccines demonstrate high efficacy. While HPV vaccines are very effective, screening for related cancers, as per guidelines, is still recommended.

Abstract
HPV, a sexually transmitted viral infection, is the etiological agent of significant dermatologic disease including benign anogenital warts and invasive cancers. Sexual and gender minority individuals are particularly vulnerable to HPV-associated disease due to reduced vaccination rates in these cohorts, low awareness of HPV, lack of provider recommendation, and inadequate consensus guidelines on screening and prevention in these individuals. A targeted approach is needed with regards to vaccination in all children -especially those from racial, ethnic, sexual, and gender minorities; provider recommendation, especially from pediatric dermatologists, is crucial. Effort must also be made to use transgender and non-binary affirming language as dividing vaccination programs by anatomic sex and sexuality reinforces problematic notions of gender identity and sexuality, isolating the most vulnerable.

Abstract
Objective: Men who have sex with men (MSM) are high-risk groups of human papillomavirus (HPV) infection, the best measure to prevent this is the HPV vaccine. However, few studies have investigated HPV vaccination willingness in the MSM population in China. We aimed to explore the willingness of human immunodeficiency virus (HIV)-negative MSM for HPV vaccination and the factors affecting their willingness to vaccinate. Methods: We adopted a non-probability sampling method to recruit HIV-negative MSM volunteers. Participants completed a questionnaire, including sociodemographic characteristics, sexual behavior characteristics, HPV infection and vaccine-related knowledge, risk perception, and HPV vaccination willingness and promotion attitudes. Results: Of the 406 HIV-negative MSM surveyed, 86.21% were willing to receive HPV vaccine. HPV infection and vaccine-related knowledge (odds ratio [OR] = 2.167, 95% confidence interval [CI] = 1.049–4.474), HPV infection risk perception (OR = 5.905, 95% CI = 1.312–26.580), and HPV vaccine promotion attitude (OR = 6.784, 95% CI = 3.164–14.546) were all related to HPV vaccination willingness. Conclusion: MSM have a high willingness for HPV vaccination. Strengthening health education for MSM, raising their awareness of HPV infection and vaccines, and promoting their risk perception of HPV infection will help increase their willingness for HPV vaccination.

Abstract
These guidelines for the treatment of persons who have or are at risk for
sexually transmitted infections (STIs) were updated by CDC after consultation
with professionals knowledgeable in the field of STIs who met in Atlanta,
Georgia, June 11–14, 2019. The information in this report updates the
2015 guidelines. These guidelines discuss 1) updated recommendations for
treatment of Neisseria gonorrhoeae, Chlamydia trachomatis,
and Trichomonas vaginalis; 2) addition of
metronidazole to the recommended treatment regimen for pelvic inflammatory
disease; 3) alternative treatment options for bacterial vaginosis; 4) management
of Mycoplasma genitalium; 5) human papillomavirus vaccine
recommendations and counseling messages; 6) expanded risk factors for syphilis
testing among pregnant women; 7) one-time testing for hepatitis C infection; 8)
evaluation of men who have sex with men after sexual assault; and 9) two-step
testing for serologic diagnosis of genital herpes simplex virus. Physicians and
other health care providers can use these guidelines to assist in prevention and
treatment of STIs.

Abstract
Human papillomavirus (HPV) is the most prevalent sexually transmitted infection worldwide and ano-genital warts (AGWs) are highly infectious. This virus is transmitted through sexual, anal, or oral contact as well as skin-to-skin contacts. Treatment for this condition has significant morbidity and it can be frustrating in certain cases. The HPV vaccination has been demonstrated as a promising strategy of secondary prevention in HPV-related diseases such as head and neck cancers, cervical diseases, and recurrent respiratory papillomatosis. Regarding AGWs, it is unclear whether vaccination can provide analogous clinical benefit. The aim of this work is to systematically review the literature regarding HPV vaccination for secondary disease prevention after treatment of AGWs. From October to December 2018, a systematic search for clinical trials was conducted in five databases: PubMed, MEDLINE, EMBASE, Cochrane, and clinicaltrials.gov using a combination of the following descriptors: 'gardasil' OR 'cervarix' OR 'nine-valent' OR '9-valent' OR 'vaccine' AND 'recurrence' OR 'relapse' AND 'hpv' OR 'papillomavirus' AND 'warts' OR 'condyloma.' Data were synthetized and entered in the Review Manager software (RevMan 5.3.5) to perform the meta-analysis. The search yielded 824 potentially relevant studies. Two studies fulfilled the eligibility criteria involving 656 participants. The meta-analysis estimated the rate of recurrence of AGWs was similar between the vaccine group and the control group. The overall effect estimate was 1.02 (0.75-1.38). This is the first meta-analysis exploring the effect of HPV vaccine in preventing the relapse of AGWs. These results suggest that HPV vaccination does not provide secondary benefit in patients with previous AGWs. However, these results cannot be generalized due to the scarce number of RCTs currently available in the literature. The outcomes from future randomized controlled trials (RCTs) are warranted to further clarify the precise effect of the vaccine.

Abstract
BACKGROUND Assessing the impact and effectiveness of HPV vaccines on anogenital warts in the United States can provide early indication of the success of vaccination programs as well as identify potential areas for improvement. METHODS Articles were identified from the PubMed, Medline, and Embase databases. Exclusion criteria were applied, and remaining studies were then classified as impact or effectiveness studies. RESULTS Eight eligible studies published through March 2018 were included. Population-based impact studies examining trends in diagnoses reported consistent declines in females ages 25 years and younger after 2006 when routine female vaccination began in the United States. Declines in males ages 25 years and younger were also seen; however, these declines were lower than those in females and more evident after routine male vaccination began in 2011. Among females and males older than 25 years, little to no change has been seen in the trends of anogenital warts since 2006. Studies that included the pre-vaccine era (before 2006) reported increasing trends during this period. After vaccine introduction, a reversal in these trends was observed. Effectiveness studies that included individual-level vaccination histories consistently demonstrated a lower risk of anogenital warts for those receiving at least one dose of the vaccine compared to those unvaccinated. CONCLUSIONS These findings suggest that the degree of HPV vaccine impact has varied substantially by age and sex. Achieving the full prevention potential of HPV vaccines will likely require greater coverage among both females and males. Post-licensure estimates of effectiveness demonstrate the real-world benefit of the vaccine.

Abstract
ObjectiveThe aim of this systematic review and meta-analysis was to review evidence supporting the use of prophylactic human papillomavirus (HPV) vaccines to influence the risk of recurrence of cervical intraepithelial neoplasia after surgical treatment.MethodsA systematic literature search was performed for publications reporting risk of recurrence of cervical intraepithelial neoplasia after surgical treatment in patients receiving HPV vaccination (either in the prophylactic or adjuvant setting). Comprehensive searches of six electronic databases (MEDLINE, Embase, Web of Science, PubMed, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and references of identified studies) from their inceptions were performed (English language only), and hand search reference lists were performed. Two independent reviewers applied inclusion and exclusion criteria to select manuscripts, with differences discussed and agreed by consensus. The literature search was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results were reported as mean differences or pooled odds ratios (OR) with 95% confidence intervals (95% CI).ResultsA total of 5744 citations were reviewed; 5 studies comprising 2912 patients were selected for the analysis. There were 1338 patients in the vaccinated group and 1574 in the placebo or unvaccinated group. The incidence of histologically confirmed cervical intraepithelial neoplasia 2+ was reduced in the vaccinated compared to the unvaccinated group (OR 0.34, 95% CI 0.21–0.54, p=< 0.00001). The number needed to treat to prevent one recurrence was 27. Both pre-treatment vaccination (OR 0.40, 95% CI 0.21–0.78, p=0.007, number needed to treat – 37) and adjuvant vaccination (OR 0.28, 95% CI 0.14–0.56, p=0.0003, number needed to treat – 30) reduced recurrence rates.ConclusionProphylactic or adjuvant HPV vaccination reduces the risk of recurrent cervical intraepithelial neoplasia 2+. These data support further investigation of its role as an adjuvant to surgical treatment.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted virus. The high-risk HPV types (i.e., HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) are considered to be the main etiological agents of genital tract cancers, such as cervical, vulvar, vaginal, penile, and anal cancers, and of a subset of head and neck cancers. Three prophylactic HPV vaccines are available that are bivalent (vs. HPV16, 18), tetravalent (vs. HPV6, 11, 16, 18), and non-avalent (vs. HPV6, 11, 16, 18, 31, 33,45, 52, 58). All of these vaccines are based on recombinant DNA technology, and they are prepared from the purified L1 protein that self-assembles to form the HPV type-specific empty shells (i.e., virus-like particles). These vaccines are highly immunogenic and induce specific antibodies. Therapeutic vaccines differ from prophylactic vaccines, as they are designed to generate cell-mediated immunity against transformed cells, rather than neutralizing antibodies. Among the HPV proteins, the E6 and E7 oncoproteins are considered almost ideal as targets for immunotherapy of cervical cancer, as they are essential for the onset and evolution of malignancy and are constitutively expressed in both premalignant and invasive lesions. Several strategies have been investigated for HPV therapeutic vaccines designed to enhance CD4+ and CD8+ T-cell responses, including genetic vaccines (i.e., DNA/ RNA/virus/ bacterial), and protein-based, peptide-based or dendritic-cell-based vaccines. However, no vaccine has yet been licensed for therapeutic use. Several studies have suggested that administration of prophylactic vaccines immediately after surgical treatment of CIN2 cervical lesions can be considered as an adjuvant to prevent reactivation or reinfection, and other studies have described the relevance of prophylactic vaccines in the management of genital warts. This review summarizes the leading features of therapeutic vaccines, which mainly target the early oncoproteins E6 and E7, and prophylactic vaccines, which are based on the L1 capsid protein. Through an analysis of the specific immunogenic properties of these two types of vaccines, we discuss why and how prophylactic vaccines can be effective in the treatment of HPV-related lesions and relapse.

Economic barriers, evidentiary gaps, and ethical conundrums: a qualitative study of physicians' challenges recommending HPV vaccination to older gay, bisexual, and other men who have sex with men. Int J Equity Health 2019; 18:159.

Abstract
BACKGROUND The human papillomavirus (HPV) is the most common sexually transmitted infection (STI) worldwide. Gay, bisexual, and other men who have sex with men (GBM), and GBM living with HIV in particular, are disproportionately impacted by HPV-associated cancers. The HPV vaccine, given early enough in life, may markedly reduce the likelihood of such cancers. In Canada, most provincial insurance programs only cover HPV vaccination for GBM up to the age of 26. Our objective was to understand physicians' everyday experiences and challenges in recommending HPV vaccination to older GBM patients. METHODS As part of the HPV Screening and Vaccine Evaluation (HPV-SAVE) Study, we conducted semi-structured interviews with 25 HIV-positive GBM patients who had received anal cancer screening and 15 service providers, including 13 physicians, who had arranged for anal cancer screening in the Canadian provinces of Ontario and British Columbia. In this analysis, we draw upon the 13 physician interviews, which were coded following Grounded Theory. RESULTS Physicians strongly supported the HPV vaccine for all GBM and considered it to be important for the management of HIV-related care. However, the overall support for HPV vaccination among physicians did not translate into consistent recommendation practices. There were two overarching factors that limited the strength/frequency of physicians' vaccine recommendation practices. First, cost/insurance coverage for some older patients impacted if and how the HPV vaccine was discussed. Second, physicians had diverse perspectives on both the prevention and therapeutic benefits of vaccinating older GBM and the reality that national guidelines are incongruent with publicly funded vaccine programs for vaccinating patients over 26 years old. These two interrelated factors have co-produced an apparent economic-evidentiary conundrum for many physicians regarding how and for whom to offer HPV vaccination. CONCLUSION Economic barriers coupled with evidentiary and guideline gaps have created clinical practice challenges for physicians and has resulted in different messages being communicated to some older GBM patients about how important HPV vaccination is for their health.

Abstract
PURPOSE OF REVIEW To gain the evidence-based knowledge concerning the efficacy of HPV vaccination for oropharyngeal sites and to highlight the trials and strategies for vaccine administration in HPV-dependent head and neck diseases. RECENT FINDINGS Vaccination can be provided in two injections. There is increasing anecdotal evidence that therapeutic vaccination is effective in treatment of recurrent respiratory papillomatosis. SUMMARY The availability and broadening spectrum of HPV vaccines make possible the prevention of cervical and other HPV-dependent diseases. Vaccination is now included in the national immunization programs of most industrial countries and will be used, it is hoped, in developing countries within the next few years. In developing countries, few women are screened for cervical precancerous lesions, making immunization even more important. In affluent countries and matured societies, with high coverage of cervical screening, the focus of interest will shift to other HPV-related diseases. The HPV vaccination is effective in preventing oral infection with types targeted by the vaccines.

PLoS Med 2019; 16:e1002756. [PMID: 30830901 PMCID: PMC6398832 DOI: 10.1371/journal.pmed.1002756] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Accepted: 01/31/2019] [Indexed: 01/21/2023] Open
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
INTRODUCTION Although human papillomavirus (HPV) routine vaccination programmes have been implemented around the world and recommendations have been expanded to include other high-risk individuals, current recommendations often differ between countries in Europe, as well as worldwide. AIM To find and summarise the best available evidence of HPV vaccination in high-risk patients aiding clinicians and public health workers in the day-to-day vaccine decisions relating to HPV in Spain. METHODS We conducted a systematic review of the immunogenicity, safety and efficacy/effectiveness of HPV vaccination in high-risk populations between January 2006 and June 2016. HPV vaccination recommendations were established with levels of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. RESULTS A strong recommendation about HPV vaccination was made in the following groups: HIV infected patients aged 9-26 years; men who have sex with men aged 9-26 years; women with precancerous cervical lesions; patients with congenital bone marrow failure syndrome; women who have received a solid organ transplant or hematopoietic stem cell transplantation aged 9-26 years; and patients diagnosed with recurrent respiratory papillomatosis. CONCLUSIONS Data concerning non-routine HPV vaccination in populations with a high risk of HPV infection and associated lesions were scarce. We have developed a document to evaluate and establish evidence-based guidelines on HPV vaccination in high-risk populations in Spain, based on best available scientific evidence.

PLoS One 2018; 13:e0207953. [PMID: 30496221 PMCID: PMC6264470 DOI: 10.1371/journal.pone.0207953] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Accepted: 11/08/2018] [Indexed: 11/22/2022] Open
Abstract
The human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. Gay, bisexual, and other men who have sex with men (GBM) living with HIV are disproportionately impacted by HPV-associated anal cancer, with rates about 100-fold that of the general population. Fortunately, HPV vaccination has proven efficacy in preventing both anogenital warts (condyloma) in males and anal pre-cancers (anal intraepithelial neoplasia; AIN) in GBM up to the age of 26. We conducted in-depth, semi-structured interviews with 25 HIV-positive gay men in Toronto to gain an understanding of their knowledge and experiences related to HPV and the HPV vaccine. These participants were part of The HPV Screening and Vaccine Evaluation (HPV-SAVE) Study, and received invitations to have anal cancer screening from their primary care doctors. Interviews were analyzed following a Grounded Theory Approach. Most participants had not received the HPV vaccine. Men described a lack of prior knowledge of the health consequences of HPV for GBM living with HIV and financial barriers to vaccine access. Participants did not articulate concerns about vaccine safety. Men frequently reported initial beliefs that HPV was predominantly-or exclusively-a risk for females or young girls, and thus they had not considered the vaccine to be necessary. Some participants remained uncertain if the current availability of the vaccine, and their newly acquired knowledge of its importance, was "too little, too late" because of their age and/or HPV exposure. Improving access and uptake of HPV vaccination requires addressing both financial barriers to access as well as increasing HPV health literacy levels, particularly by reframing the long-standing gendered associations of HPV. Physicians should provide clear, tailored messages regarding HPV vaccination.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is safe and effective in preventing cervical cancer in females. As HPV infections can also induce cancers of the anus, penis and oral cavity, male vaccination is also advocated, but systematic reviews on efficacy and safety in males are lacking. METHODS We performed a systematic review on the efficacy, effectiveness and safety of HPV vaccination in males of any age. MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were searched from inception to April 2017. RESULTS We identified 5196 articles and seven studies (four randomized controlled trials (RCTs), three non-randomized studies) were included, comprising a total of 5294 participants. Vaccine efficacy against at least 6-month persisting anogenital HPV 16 infections was 46.9% (95% confidence interval (CI) 28.6-60.8%), whereas efficacy against persisting oral infections was 88% (2-98%). A vaccine efficacy of 61.9% (21.4-82.8%) and 46.8% (- 20 to -77.9%) was observed against anal intraepithelial neoplasia grade 2 and grade 3 lesions, respectively. No meaningful estimates were available on vaccine efficacy or effectiveness against penile intraepithelial neoplasia grade 2 or 3, and no data were identified for anal, penile or head and neck squamous cell cancer. In participants who were HPV-seronegative and PCR-negative at enrolment, efficacy against all outcomes was higher as compared to seropositive and/or PCR-positive individuals. Risk of bias was low in three RCTs and high in one, while the three non-randomized studies were at serious to critical risk of bias. Grading of Recommendations Assessment, Development and Evaluation evidence quality was moderate to low for most outcomes. CONCLUSIONS HPV vaccination in males is moderately effective against persistent anogenital HPV infection and high-grade anal intraepithelial lesions in studies where the population consists mainly of HPV-infected males. Vaccine effectiveness was high in study groups comprising HPV-naïve males. This supports a recommendation for vaccination of boys before the onset of sexual activity with the goal of establishing optimal vaccine-induced protection. Mathematical modelling studies will still be needed to assess the effects of adding males to existing HPV vaccination programs in females.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) are at disproportionately high risk for anal cancer. There is no definitive approach to the management of high-grade squamous intraepithelial lesions (HSIL), which are precursors of anal cancer, and evidence suggests that posttreatment adjuvant quadrivalent human papillomavirus (qHPV) vaccination improves HSIL treatment effectiveness. The objectives of this study were to evaluate the optimal HSIL management strategy with respect to clinical effectiveness and cost-effectiveness and to identify the optimal age for initiating HSIL management. METHODS A decision analytic model of the natural history of anal carcinoma and HSIL management strategies was constructed for HIV-positive MSM who were 27 years old or older. The model was informed by the Surveillance, Epidemiology, and End Results-Medicare database and published studies. Outcomes included the lifetime cost, life expectancy, quality-adjusted life expectancy, cumulative risk of cancer and cancer-related deaths, and cost-effectiveness from a societal perspective. RESULTS Active monitoring was the most effective approach in patients 29 years or younger; thereafter, HSIL treatment plus adjuvant qHPV vaccination became most effective. When cost-effectiveness was considered (ie, an incremental cost-effectiveness ratio [ICER] < $100,000/quality-adjusted life-year), do nothing was cost-effective until the age of 38 years, and HSIL treatment plus adjuvant qHPV vaccination was cost-effective beyond the age of 38 years (95% confidence interval, 34-43 years). The ICER decreased as the age at HSIL management increased. Outcomes were sensitive to the rate of HSIL regression or progression and the cost of high-resolution anoscopy and biopsy. CONCLUSIONS The management of HSIL in HIV-positive MSM who are 38 years old or older with treatment plus adjuvant qHPV vaccination is likely to be cost-effective. The conservative approach of no treatment is likely to be cost-effective in younger patients. Cancer 2017;123:4709-4719. © 2017 American Cancer Society.

Abstract
BACKGROUND Persistent high-risk human papillomavirus (HR-HPV) infection is associated with the development of anogenital cancers, particularly in men living with HIV (MLWH). We describe the prevalence of anogenital HPV infection, abnormal anal cytology and anogenital warts (AGWs) in MLWH in Johannesburg, and explore whether HPV infection and receipt of antiretroviral treatment is associated with detection of abnormal anal cytology and AGWs. METHODS We enrolled a cohort of 304 sexually-active MLWH ≥18 years, who completed a questionnaire and physical examination. Genital swabs were collected from all men and intra-anal swabs from 250 (82%). Swabs were tested for HPV DNA and genotypes, and anal smears graded using the Bethesda classification. Factors associated with anogenital disease were assessed by logistic regression models. RESULTS Two thirds were receiving antiretroviral treatment, for a median 33 months (IQR = 15-58) and 54% were HIV-virologically suppressed. Only 5% reported ever having sex with men. Among 283 genital swabs with valid results, 79% had any HPV, 52% had HR-HPV and 27% had >1 HR-HPV infection. By comparison, 39% of the 227 valid intra-anal swabs had detectable HPV, 25% had any HR-HPV and 7% >1 HR infection. While most anal smears were normal (51%), 20% had ASCUS and 29% were LSIL. No cases had HSIL or cancer. Infection with >1 HR type (adjusted OR [aOR] = 2.39; 95%CI = 1.02-5.58) and alpha-9 types (aOR = 3.98; 95%CI = 1.42-11.16) were associated with having abnormal cytology. Prevalence of AGWs was 12%. Infection with any LR type (aOR = 41.28; 95%CI = 13.57-125.62), >1 LR type (aOR = 4.14; 95%CI = 1.60-10.69), being <6 months on antiretroviral treatment (aOR = 6.90; 95%CI = 1.63-29.20) and having a CD4+ count <200 cells/μL (aOR = 5.48; 95%CI: 1.60-18.78) were associated with having AGWs. CONCLUSIONS In this population, anogenital HR-HPV infection and associated low-grade disease is common, but severe anal dysplasia was not detected. Findings reinforce the need for HPV vaccination in men for preventing both AGWs and HR-HPV infection. Given the absence of anal HSILs, however, the findings do not support the use of anal screening programmes in this population.

Abstract
Background Men who have sex with men (MSM), particularly HIV-infected MSM are disproportionately affected by HPV infection and associated disease. The HPV vaccine has potential to greatly reduce the burden of HPV-associated disease including anal cancer in MSM. The efficacy of the HPV vaccine is dependent on high levels of vaccine uptake. The aim of this study was to examine HPV vaccine acceptability and factors influencing vaccine acceptability in MSM in Ireland. Methods A self-administered survey was distributed to HIV-infected and HIV negative MSM examining HPV vaccine acceptability and factors associated with vaccine acceptability. Logistic regression was used to identify key variables and predictors of HPV vaccine acceptability. Results 302 MSM participated in the study. Acceptability of HPV vaccine was 31% (unconditional), 51% (conditional on stated efficacy and a cost of €300), 65% (conditional on stated efficacy and a cost of €100) and 78% (conditional on stated efficacy and no cost). Cost was negatively associated with HPV vaccine acceptability (p<0.01) while knowledge of HPV vaccine efficacy was significantly associated with vaccine acceptability, even in the context of associated cost (p<0.01). Conclusions Acceptability of HPV vaccine in MSM in Ireland is high based on no cost vaccine and on stated vaccine efficacy (78%). Cost is negatively associated with vaccine acceptability. Understanding levels of knowledge of HPV infection, HPV associated disease and attitudes toward HPV vaccination are important as they will contribute to HPV vaccine acceptability among MSM and will help guide effective preventive programs.

Abstract
Diseases associated with the human papilloma virus (HPV) are particularly common among men who have sex with men (MSM). Unlike heterosexual men, MSM do not benefit from the herd protection provided by the vaccination of girls. In this review, we synthesize the available evidence on HPV vaccination for MSM. We also present the recommendations of the Québec Immunization Committee (CIQ) in this regard, which are: to provide targeted vaccination for MSM up to 26 years of age and in-school vaccination of preadolescent boys since this is the best approach to take to have a real impact on the burden related to HPV in the MSM population and to provide direct protection for all men.

An anal cancer screening program for MSM in Italy: Prevalence of multiple HPV types and vaccine-targeted infections. J Clin Virol 2015; 72:49-54. [PMID: 26397204 DOI: 10.1016/j.jcv.2015.09.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Revised: 09/06/2015] [Accepted: 09/07/2015] [Indexed: 12/16/2022]
Abstract
BACKGROUND Elevated HPV infection rates have been described in HIV-positive males, placing these subjects at high risk of anal neoplasia. Bivalent, quadrivalent, and nonavalent vaccines to prevent HPV infection have been developed, and recently proposed for gender-neutral immunization programs. OBJECTIVES In order to estimate the benefit that could be obtained by vaccination of HIV-positive men who have sex with men (MSM), we aimed at describing the frequency of multiple and vaccine-targeted HPV infections in MSM enrolled in an anal cancer screening program. STUDY DESIGN The anal cancer screening program was conducted between July 2009 and October 2012. Mucosal anal samples were tested for HPV DNA using MY09/MY11 PCR primers and, if positive, genotyped using the CLART2HPV Clinical Array (35HPV types). RESULTS A total of 220 MSM were screened and 88.6% were positive for HPV DNA: in 86.5% at least one high-risk (HR) type was found and in 13% only low-risk (LR) HPV were found. Multiple infections accounted for 84.5% of HPV DNA-positive cases and overall 160 different HPV genotype combinations were recognized (only three combinations were detected in more than one patient each). Based on strain coverage, at least one vaccine-targeted HPV type was found in 38.9%, 64%, and 78.4% of cases when considering bivalent, quadrivalent and nonavalent vaccines, respectively. At least one HR vaccine-targeted strain was found in 39% of MSM for bivalent and quadrivalent vaccines, and in 64% of cases for nonavalent prevention. CONCLUSIONS Anal HPV infections in unvaccinated mostly HIV-infected MSM are highly prevalent. The majority of this population has multiple infections with an extremely heterogeneous number of genotype combinations. The nonavalent vaccine could theoretically have prevented a minimum of one HR HPV type in two thirds of subjects.

Abstract
BACKGROUND Recent evidence shows that quadrivalent human papillomavirus (qHPV) vaccination in men who have sex with men (MSM) who have a history of high-grade anal intraepithelial neoplasia (HGAIN) was associated with a 50% reduction in the risk of recurrent HGAIN. We evaluated the long-term clinical and economic outcomes of adding the qHPV vaccine to the treatment regimen for HGAIN in human immunodeficiency virus (HIV)-positive MSM aged ≥27 years. METHODS We constructed a Markov model based on anal histology in HIV-positive MSM comparing qHPV vaccination with no vaccination after treatment for HGAIN, the current practice. The model parameters, including baseline prevalence, disease transitions, costs, and utilities, were either obtained from the literature or calibrated using a natural history model of anal carcinogenesis. The model outputs included lifetime costs, quality-adjusted life years, and lifetime risk of developing anal cancer. We estimated the incremental cost-effectiveness ratio of qHPV vaccination compared to no qHPV vaccination and decrease in lifetime risk of anal cancer. We also conducted deterministic and probabilistic sensitivity analyses to evaluate the robustness of the results. RESULTS Use of qHPV vaccination after treatment for HGAIN decreased the lifetime risk of anal cancer by 63% compared with no vaccination. The qHPV vaccination strategy was cost saving; it decreased lifetime costs by $419 and increased quality-adjusted life years by 0.16. Results were robust to the sensitivity analysis. CONCLUSIONS Vaccinating HIV-positive MSM aged ≥27 years with qHPV vaccine after treatment for HGAIN is a cost-saving strategy. Therefore, expansion of current vaccination guidelines to include this population should be a high priority.

Abstract
An investigational monovalent human papillomavirus (HPV) 16 virus-like particle vaccine has been shown to prevent persistent infection and cervical disease related to HPV 16 and was proof of concept (2002). Designed to prevent the bulk of invasive cervical cancer, quadrivalent (HPV 6/11/16/18) and bivalent (HPV 16/18) vaccines have been available since 2006 and 2007, respectively. They are highly effective in preventing HPV 16/18-related cervical precancer; the quadrivalent version also prevents genital warts related to HPV 6/11. It has been shown that the precursors of vulvar, vaginal and anal cancer related to the vaccine types are effectively prevented. This led to a paradigm shift from a female-only cervical cancer vaccine to a vaccine for the prevention of HPV-related disease and cancer for both sexes. Vaccination before the start of sexual activity is most effective, and consequently most programs target 9- to 12-year-olds. Additionally, recent studies have proven the noninferior immunoresponse of a two-dose schedule in these age cohorts. Gender-neutral vaccination has become more common; it improves coverage and also provides protection to all males. Recently a nine-valent HPV vaccine (HPV 6/11/16/18/31/33/45/52/58) was licensed; it provides high and consistent protection against infections and diseases related to these types, with ∼90% of cervical and other HPV-related cancers and precancers potentially being avoided. Coverage is key. Efforts must be made to provide HPV vaccination in low-resource countries that lack screening programs. In countries with cervical cancer screening, HPV vaccination will greatly affect screening algorithms.

Abstract
Background: Human papillomavirus (HPV) vaccination of girls will have relatively little effect on HPV-related disease in men who have sex with men (MSM). We determined HPV prevalence and risk factors in MSM to inform the potential effectiveness of vaccinating MSM. Methods: Cross-sectional study of 522 MSM aged 18–40 attending a London sexual health clinic who completed a computer-assisted self-interview. Urine and two swabs (anal and penile/scrotal/perianal) were collected and tested using an in-house Luminex-based HPV genotyping system. Results: Prevalence of DNA of the vaccine-preventable HPV types in ano-genital specimens of men was 87/511 (17.0%), 166/511 (32.5%) and 232/511 (45.4%) for the bivalent (HPV16/18), quadrivalent (HPV6/11/16/18) and nonavalent (HPV6/11/16/18/31/33/45/52/58) vaccine types, respectively. A total of 25.1% had one of the quadrivalent types, and 7.4% had 2+ types. Median age at first anal sex was 19 (IQR 17–23) and at first clinic attendance was 24 (IQR 20–27). The increase in the odds of any HPV infection per year of age was 4.7% (95% CI 1.2–8.4). Conclusions: On the basis of the current infection status, most MSM, even among a high-risk population attending a sexual health clinic, are not currently infected with the vaccine-type HPV. A targeted vaccination strategy for MSM in the UK could have substantial benefits.

Abstract
The commonest sights of appearance of condylomata acuminata are in the genital and anal regions. Herein we present two cases of condylomata within perianal fistulae tracts, resulting in recurrence in one case and a malignant-like tumour in the second. To our knowledge, these are the first cases reported in the literature.
