Stern PL. Is immunotherapy a potential game changer in managing human papillomavirus (HPV) infection and intraepithelial neoplasia? Tumour Virus Res 2023; 16:200263. [PMID: 37236509 PMCID: PMC10774942 DOI: 10.1016/j.tvr.2023.200263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 05/24/2023] [Indexed: 05/28/2023] Open
Abstract
The International Papillomavirus Conference was held in Washington DC in April 2023 and encompassed wide ranging basic, clinical and public health research relating to animal and human papillomaviruses. This editorial is a personal reflection, it does not attempt to be comprehensive and reports on some key aspects centred on the prospects for immune interventions in prevention and treatment of HPV infections and early precancers with a focus on cervical neoplasia. There is optimism for the future impact of immunotherapy in treating early HPV associated disease. This will depend on developing an appropriate design of vaccines and delivery vehicles which then need to be properly tested in clinical trials that are able to measure a useful clinical endpoint. Thereafter vaccines (prophylactic or therapeutic) still need global access and sufficient uptake to deliver impact and a key and necessary driver is education.

Photodiagnosis Photodyn Ther 2023; 43:103696. [PMID: 37429462 DOI: 10.1016/j.pdpdt.2023.103696] [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: 11/29/2022] [Revised: 07/07/2023] [Accepted: 07/07/2023] [Indexed: 07/12/2023]
Abstract
BACKGROUND AND OBJECTIVES Aminolaevulinic acid-mediated photodynamic therapy (ALA-PDT) is increasingly applied for the treatment of condyloma acuminata (CA). However, the determinants for the sessions and end points of ALA-PDT treatment remains unclear. Here, we recorded HPV screening, evaluated the frequency and efficacy of ALA-PDT in different types of CA, in order to individualize ALA-PDT treatment to CA. METHODS A total of 227 CA patients with HPV infection and visible warts were recruited. Prior to PDT, visible lesions were removed by radio frequency or microwave. HPV DNA detection were performed before each PDT treatment and at follow-up. Treatment was ended after two consecutive negative HPV DNA detection. RESULTS Of the 227 patients, 119 patients received ALA-PDT and 116 patients completed all treatments. We found that CA patients with multiple-site infection, intra-luminal infection or multiple-type of HPV infection required more sessions of ALA-PDT. The recurrence rate was 8.62% (10/116). Viral load was significantly lower after six PDT treatments compared to viral load after three PDT treatments. Gender, HPV subtypes and warts location had no significant effect on the recurrence rate. CONCLUSION Comprehensive evaluation of HPV infection state helps to individualize ALA-PDT treatment scheme for CA patients and predict the therapeutic efficacy.

Vaccines (Basel) 2023; 11:vaccines11020443. [PMID: 36851321 PMCID: PMC9958554 DOI: 10.3390/vaccines11020443] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 02/09/2023] [Accepted: 02/13/2023] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) infection is the most common sexually transmitted viral infection in the world. HPV vaccination adherence rates in men are generally lower than in women. The aim of this systematic review and meta-analysis was to assess adherence to HPV vaccination in young working-age males (18-30 years old). METHODS A systematic review was performed using three databases: PubMed, Scopus, and Web of Science, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS After duplicate removal, the initial search resulted in 478 eligible papers. With the exclusion of 425 papers after screening the abstracts, full texts of 53 articles were reviewed. Subsequently, 45 were excluded. Among the eight studies included, four (50%) examined the vaccination adherence in young adults through data registered in nationwide insurance or private companies' databases, three (37.5%) in young adults in different settings through data collected from surveys and questionnaires, and one (12.5%) an HPV vaccination campaign in a family medicine residency practice. CONCLUSION Adherence to HPV vaccination in men of working age (18-30 years) does not appear to be adequate (pooled prevalence 11%). In order to achieve a higher level of compliance, it is important to place an emphasis on vaccination campaigns in schools as well as in the workplace, after consultation with and approval from local, regional, and federal public health agencies.

Maximizing the cost-effectiveness of cervical screening in the context of routine HPV vaccination by optimizing screening strategies with respect to vaccine uptake: a modeling analysis. BMC Med 2023; 21:48. [PMID: 36765349 PMCID: PMC9921628 DOI: 10.1186/s12916-023-02748-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Accepted: 01/23/2023] [Indexed: 02/12/2023] Open
Abstract
BACKGROUND Regarding primary and secondary cervical cancer prevention, the World Health Organization proposed the cervical cancer elimination strategy that requires countries to achieve 90% uptake of human papillomavirus (HPV) vaccines and 70% screening uptake. The optimal cervical screening strategy is likely different for unvaccinated and vaccinated cohorts upon national HPV immunization. However, health authorities typically only provide a one-size-fits-all recommendation for the general population. We aimed to evaluate the cost-effectiveness for determining the optimal screening strategies for vaccinated and unvaccinated cohorts. METHODS We considered the women population in Hong Kong which has a unique HPV infection and cervical cancer epidemiology compared to other regions in China and Asia. We used mathematical models which comprise a deterministic age-structured compartmental dynamic component and a stochastic individual-based cohort component to evaluate the cost-effectiveness of screening strategies for cervical screening. Following the recommendations in local guidelines in Hong Kong, we considered strategies that involved cytology, HPV testing, or co-testing as primary cervical screening. We also explored the impacts of adopting alternative de-intensified strategies for vaccinated cohorts. The 3-year cytology screening was used as the base comparator while no screening was also considered for vaccinated cohorts. Women's lifetime life years, quality-adjusted life years, and costs of screening and treatment were estimated from the societal perspective based on the year 2022 and were discounted by 3% annually. Incremental cost-effectiveness ratios (ICERs) were compared to a willingness to pay (WTP) threshold of one gross domestic product per capita (US $47,792). Probabilistic and one-way sensitivity analyses were conducted. RESULTS Among unvaccinated cohorts, the strategy that adds reflex HPV to triage mild cytology abnormality generated more life years saved than cytology-only screening and could be a cost-effective alternative. Among vaccinated cohorts, when vaccine uptake was 85% (based on the uptake in 2022), all guideline-based strategies (including the cytology-only screening) had ICERs above the WTP threshold when compared with no screening if the vaccine-induced protection duration was 20 years or longer. Under the same conditions, HPV testing with genotyping triage had ICERs (compared with no screening) below the WTP threshold if the routine screening interval was lengthened to 10 and 15 years or screening was initiated at ages 30 and 35 years. CONCLUSIONS HPV testing is a cost-effective alternative to cytology for vaccinated cohorts, and the associated optimal screening frequency depends on vaccine uptake. Health authorities should optimize screening recommendations by accounting for population vaccine uptake.

Abstract
BACKGROUND Seven high-risk human papillomavirus (HPV) types (16/18/31/33/45/52/58) covered by the 9-valent HPV (9vHPV) vaccine cause >90% of HPV-related head and neck cancers (HNCs). An ongoing clinical trial (NCT04199689) was designed to evaluate 9vHPV vaccine efficacy against HPV oral persistent infection, a surrogate endpoint for HPV-related HNCs. METHODS In this double-blind, placebo-controlled, international trial, men aged 20-45 years (N = 6000) are randomized 1:1 to receive 9vHPV vaccine or placebo on day 1, month 2, and month 6. The primary objective is to demonstrate whether 9vHPV vaccination reduces incidence of HPV16/18/31/33/45/52/58-related 6-month oral persistent infection. Incidence of HPV6/11-related 6-month oral persistent infection will be evaluated as a secondary endpoint. Oral rinse and gargle samples will be collected on day 1, month 7, month 12, and every 6 months thereafter for HPV detection by PCR. Primary analyses will be performed in per-protocol populations. Efficacy in this case-driven study will be analyzed upon accrual of ≥20 primary efficacy endpoint cases. Serum will be collected at day 1 and months 7, 12, 24, 36, and 42; anti-HPV antibody titers will be measured by competitive Luminex immunoassay. Data will be summarized as geometric mean titers and seropositivity rates. Injection-site and systemic adverse events (AEs) will be collected for 15 days post-any vaccination and serious AEs through 6 months after the last vaccination; deaths and vaccine-related serious AEs will be collected throughout the study. DISCUSSION This trial is expected to generate important data regarding the potential for 9vHPV vaccine to prevent HPV-related head and neck disease.

Abstract
The prevalence of HPV infection and its relationship with other sexually transmitted infections was analyzed in a cohort of 117 male partners of infertile couples from Cordoba, Argentina. Semen samples and urethral swabs were obtained and the infection with HPV, Chlamydia trachomatis, HSV1, HSV2, Mycoplasma hominis and Ureaplasma urealyticum was analyzed. A prevalence of HPV infection of 27.4% was found. Interestingly, infections by exclusively low risk HPV genotypes or high/intermediate risk HPV genotypes were present in 64.5% and 22.6% of cases, respectively. Low risk-HPV6 was the most frequently detected genotype. Remarkably, HPV and C. trachomatis infections were significantly associated to each other (OR: 11.55, 95% CI 1.14-117.06). No significant differences in sperm quality were found between HPV-positive and HPV-negative patients indicating that HPV male urogenital infection does not impair sperm quality. Our results show a high prevalence of HPV urogenital infection among male partners of infertile couples, and that HPV and C. trachomatis infections are reciprocal risk factors of their co-infection. Moreover, our results suggest that men constitute a reservoir for continued transmission of C. trachomatis and HPV to women highlighting the need for routine screening for these two pathogens in male partners of infertile couples.

Abstract
External anogenital warts (EGW) are primarily associated with the low-risk human papillomavirus (HPV) genotypes 6 and 11, though coinfection with other low-risk and oncogenic high-risk HPV genotypes also occurs. Although there have been many studies on HPV-associated disease, the prevalence of HPV genotypes associated with EGW is not well characterized. The objective of our retrospective study was to determine the prevalence of HPV genotypes among patients diagnosed with EGW in the south-west of Hungary. Archived formalin-fixed paraffin-embedded tissues from 94 patients were processed in our study. HPV genotypes were determined, applying HPV Direct Flow CHIP test. The overall prevalence of HPV DNA in the EGW samples was 100%, yielding 131 infections among the 94 samples. Of these cases, 72.3% were mono while 27.6% were multi-infections. Out of the 131 infections, the cumulative prevalence of HPV 6 and 11 was 71%. A total of 98.9% of the samples were carrying at least one of these genotypes, while 19.1% of the cases occurred with at least one high-risk genotype. Data from our study could provide invaluable information concerning the prevalence of HPV types among patients with EGW, enabling improved assessment of the actual and future efficacy of vaccination programs, vaccine development, and forecast changes in infection patterns.

Abstract
BACKROUND Keratinocyte carcinoma (KC) mortality is relatively modest and its measures are subject to considerable error. Deaths due to KC have been decreasing through 2000 and were relatively stable until 2010. OBJECTIVE To estimate the KC mortality rates (MRs) from 2011 to 2017 in USA based on death certificates. METHODS A population-based analysis of Center of Disease Control and Prevention data. Main outcomes and measures were the age-adjusted (US 2000 standard population) MRs. RESULTS Overall, KC MRs increased significantly (b = 0.04, p < .01). For the period studied, KC MR was 1.24 per 100,000 persons per year (0.62 for sun-exposed sites, 0.38 for genital and 0.23 for perianal sites). At sun-exposed genital and perianal anatomic sites, KC MRs have been increasing in whites, but not in blacks. CONCLUSION There was a 17% decrease in the KC MRs until 2000, followed by an increase of 44% through 2017. The accuracy of KC MRs is uncertain. If indeed the increase in mortality is verified, causes may include an increase in KC incidence, an increase of immunosuppressed populations, and changes in the cause of death documentation.

Abstract
Infection with human papilloma virus (HPV) is related to a great number of cutaneous and mucosal manifestations. The spectrum of HPV ranges from inapparent infections, through various clinical benign presentations including cutaneous and mucosal disease, to malignant and premalignant conditions. New HPV types are currently described in the literature; many of them are characterized as high-risk types due to their oncogenic potential. Knowledge regarding their epidemiology and pathogenesis is important to understand not only infection and disease processes, but also to formulate the clinical and laboratory basis for diagnosis, therapeutics, and prophylactic measures. This non-systematic review aims to discuss and to update those aspects, with an emphasis on relevant topics for dermatologists. HPV infection and related diseases in the Brazilian scenario are highlighted, including common dermatologic conditions seen at clinics as well as the condition of a public health problem as a sexually transmitted infection. The oncogenicity of the virus and the variety of clinical outcomes - especially in the immunocompromised individuals - are addressed.

Contemporary human papillomavirus genotyping and correlations to peniscopy, cytology, and histopatology on over 1000 males. Diagn Cytopathol 2020; 48:1021-1026.

Abstract
OBJECTIVES To explore male human papillomavirus (HPV) contemporary genotyping epidemiology and correlations to peniscopy, cytology, and histopatology. METHODS Medical records of patients who had been submitted to HPV infection screening with genotyping, peniscopy, cytology, and histopathology in a period of 2 years were reviewed. Frequency analysis and correlations between the diagnostic tools were established. RESULTS Genotype of 1132 men resulted in 69.2% (784) positivity for HPV DNA, 78% classified as high risk of oncogenesis. Co-infections occurred in 429 (54.7%) and the most frequently identified types were HPV-6, HPV-42, and HPV-16, in 133 (17%), 94 (12%), and 86 (11%) patients, respectively. Positive/negative predictive values of peniscopy, cytology, and histopathology were 83/31%, 92/32%, and 87/33%, respectively. As a result, though significant, the correlations between genotype and non-molecular tests were poor. CONCLUSIONS In the current contemporary representative male cohort, over two thirds are positive for human HPV DNA, 78% of high risk and with over half co-infections. Though significant, its correlation with non-molecular tests is poor and while the positive predictive values of peniscopy, cytology, and histopatology are between 83% and 92%, their negative predictive values are as low as 31% to 33%.

Abstract
Men who have sex with men (MSM) attending university are a high-risk population for human papillomavirus (HPV) infection and are a neglected population of HPV vaccination programs in China. To provide evidence for HPV vaccination policies, we conducted this study to examine the prevalence and factors associated with anal HPV infection among MSM attending university in China. A self-administered online questionnaire was conducted to collect information on social demographics and sexual behaviors. A self-collected rectal swab specimen was collected to test for 37 HPV types. A total of 426 participants were tested for HPV. The median age was 20 years. HPV prevalence was 37.5% for any type, 29.8% for nine-valent vaccine types, 24.6% for four-valent vaccine types, 11.5% for HPV-16/18, and 15.7% for HPV-6/11. Men enrolled in a technical diploma, living in Northern China, having more than two sex partners, being bottom or versatile in anal sex, and having a human immunodeficiency virus (HIV) testing history were more likely to have positive anal HPV of any type. Our study found a high prevalence of anal HPV infection among MSM attending university in China, with HPV vaccine-preventable types being the most popular types in this group. Thus, our findings highlight the urgency of promoting HPV vaccination among teenage MSM.
