Abstract
The current study aimed to investigate the sequence variations of HPV 51 and 59 in normal cervical cells and premalignant/malignant lesions of the cervix to know the common variants of HPV 51 and HPV 59 circulating in Iran. To do this, eighty-five samples that were infected by HPV 51 or HPV 59 were investigated using hemi-PCR to amplify the E6 gene followed by sequencing. Our findings indicated that lineages A and B were detected in 80.4% and 19.6% of HPV 51-positive cases, respectively. Among samples infected with HPV 59, 32.2% belonged to lineage A and 67.8% were classified with lineage B. In conclusion, our results showed that lineage A of HPV 51 and lineage B of HPV 59 are more prevalent and distributed in Iran.

[PMID: 38952402 PMCID: PMC11215532 DOI: 10.1002/hsr2.2158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 03/17/2024] [Accepted: 05/15/2024] [Indexed: 07/03/2024] Open
Abstract
Background and Aims Knowing the regional variants of distinct human papillomavirus (HPV) types is valuable as it can be beneficial for studying their epidemiology, pathogenicity, and evolution. For this reason, the sequence variations of the E6 gene of HPV 52 were investigated among women with normal cervical cytology and premalignant/malignant cervical samples. Methods Sixty-four HPV 52-positive samples were analyzed using semi-nested PCR and sequencing. Results Our findings showed that all samples belonged to lineage A (61%) or B (39%). Among samples that were infected with the A lineage, sublineages A1 and A2 were detected and sublineage A1 was dominant. No association was found between lineages and stage of disease (p > 0.05). Conclusion Our results revealed that the A lineage, sublineage A1, and B lineage were common in Iranian women. Nevertheless, more studies with larger sample sizes are required to estimate the pathogenicity risk of HPV 52 lineages in Iranian women with cervical cancer.

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: 39] [Impact Index Per Article: 39.0] [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
Human papillomavirus (HPV) infection in men is a serious issue because it is associated with genital warts, anogenital cancers, and HPV transmission to their sex partners. This study aimed to investigate the prevalence and genotypes of HPVs in Vietnamese male patients hospitalized with sexually transmitted infection (STI) symptoms between 2016 and 2020 by using polymerase chain reaction and reverse dot blot hybridization analysis. HPV DNA was detected in 191/941 (20.3%) penile cell samples. The HPV patient's mean age was 30.3 in the range of 16- and 69-year-old. The highest HPV prevalence (84.7%) was found in patients between 20- and 39-year-old. A total of 313 HPV genotypes were identified. The multiple-infection rate was 42.9%. The most common high-risk (HR)-HPV genotypes were HPV-16 (8.0%), HPV-51 (7.7%), HPV-52 (4.8%), HPV-56 (4.2%), and HPV-18 (3.8%). Furthermore, HPV-11 and HPV-6 genotypes were the two most common low-risk (LR)-HPV genotypes with the rate of 36.7% and 21.4%, respectively. Notably, HPV-52 was found circulating in Vietnam for the first time. In conclusion, this study results showed that HPV prevalence in Vietnamese male patients was common and diverse. In addition, regarding public health and cancer prevention, the inclusion of the HPV vaccination into the national vaccination program for both men and women is recommended.

Abstract
Knowing the regional lineages/sublineages of human papillomavirus 31 (HPV 31) and 45 would be of great importance for further evolutionary, epidemiological, and biological analysis. In this regard, to characterize more common lineages and sublineages of HPV 31 and 45, the sequence variations of E6 gene were investigated in normal, premalignant, and malignant samples collected from the cervix in Iran. In total, 54 HPV 31- and 24 HPV 45-positive samples were analyzed by hemi-nested polymerase chain reaction (PCR) and nested-PCR, respectively. All PCR products were subjected to direct sequencing analysis. The results indicated that all three lineages A, B, and C were detected in HPV 31-positive samples; among which HPV 31 lineage A was dominant as it was found in 66.7% of all samples. HPV 31 lineages B and C were identified in 5.5% and 27.8% of samples, respectively. In HPV 45-infected samples, lineage B comprised of 62.5% of all samples and the remaining 37.5% belonged to lineage A. In conclusion, our findings showed that lineage A of HPV 31 was predominant in Iran. Lineage B of HPV 45 was also dominant among Iranian women. However, further studies with larger sample size should be addressed to estimate the pathogenicity risk of HPV 31 or HPV 45 lineages/sublineages in the development of cervical cancer among Iranian women.

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
Background Men who have sex with men (MSM) are at high risk of developing human papillomavirus (HPV)-related anal cancer. We compared HPV genotypes in anal tissues (Bx) and anal liquid-based cytology fluid (LBC) from HIV-positive and HIV-negative MSM. Methods Bx (32 normal, 41 low-grade squamous intraepithelial lesions (LSIL) and 22 high-grade squamous intraepithelial lesions (HSIL)), along with LBC from the same visit, were selected from 61 HIV-positive and 34 HIV-negative MSM who enrolled into a prospective cohort in Bangkok, Thailand. HPV genotyping was performed on Bx and LBC. Results Any HPV and high-risk HPV (HR-HPV) prevalence were 63.2% and 60.0% in Bx and 71.6% and 62.1% in LBC, respectively. HIV-positive MSM had higher rates of HR-HPV genotypes detection (70.5% vs. 47.1%, p=0.03) in LBC than HIV-negative MSM. HPV16 (27%) was the most common HR-HPV found in HSIL tissue. In HIV-positive MSM, the frequency of HR-HPV detection increased with histopathologic grading in both Bx and LBC samples. HSIL was associated with the presence of any HR-HPV(OR 7.6 (95%CI 1.8–31.9); P=0.006) in LBC and in Bx((OR 5.6 (95%CI 1.4–22.7); P=0.02). Conclusions Our data strongly support the integration of HR-HPV screening on LBC samples, along with HPV vaccination, into an anal cancer prevention program.

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
This cross-sectional study investigated the prevalence, genotypes, and risk factors for human papillomavirus (HPV) infection in Hanoi, Vietnam. The study included 192 males (mean age, 32.9 years) with symptoms related to sexually transmitted infections (STI). Urinary, penile, and urethral samples were collected in April and May, 2014. HPV DNA was detected with PCR, performed with modified and/or original GP5(+)/GP6(+) primers. HPV genotypes were determined with a gene array assay. Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) DNA were detected with loop-mediated isothermal amplification. HPV DNA, NG, and CT were detected in 48 (25.0%), 23 (12.0%), and 41 (21.4%) patients, respectively. HPV DNA appeared in penile samples (21.0%, 39/186) more frequently than in urinary (3.1%, 6/191, P < 0.001) and urethral (9.4%, 18/192, P = 0.002) samples. Among patients with HPV, genotype prevalence was: HPV81 (22.9%), HPV52 (18.8%), HPV18 (16.7%), and HPV16 (6.3%). Multiple-type and high risk-type HPV infections were determined in 33.3% and 64.6%, respectively. Multivariate analysis showed a significant association of HPV infection in urethra with younger sexual debut age. HPV52 was the most prevalent high-risk HPV genotype, whereas HPV16 was less common in the male Vietnamese patients with STI-related symptoms. Younger sexual-debut age was a risk factor for HPV infection in urethra.

Abstract
INTRODUCTION Human papillomavirus (HPV) and anal carcinoma are prevalent in high-risk patients including human immunodeficiency virus (HIV)-positive patients. There are currently no clear guidelines for screening, however. We assessed anal cytology specimens and HPV testing at an inner-city hospital by correlating anal cytology with anal biopsy (bx), and evaluated if results differed with traditional proctoscopy (TP) or high-resolution anoscopy (HRA). MATERIALS AND METHODS 209 anal cytology and subsequent biopsies taken during the period 2003-2014 from 152 male patients were reviewed. Demographic data for age, sex, HIV, HPV, cytology, histology, and the method of biopsy were analyzed. RESULTS All specimens were followed by a biopsy within a period of 6 months. Ninety-seven percent of patients were HIV-positive and 43% had AIDS. Lesions most diagnosed on cytology were low-grade squamous intraepithelial lesion (LSIL) (52%) and atypical squamous cells of undetermined significance (ASC-US) (21.5%). Lesions most diagnosed on bx were anal intraepithelial neoplasia (AIN) grade 2-3 (52%) and AIN grade 1 (37%). Almost all ASC-US cases tested for HPV were positive (97%). There was cytology histology correlation in 48% of LSIL and 83% of high-grade squamous intraepithelial lesions. Anal cytology had 97% sensitivity in detecting AIN and carcinoma and a positive predictive value of 96%. There was no difference in rate of detection of AIN 1and AIN 2-3 on bx using TP versus HRA. CONCLUSION Screening in high-risk patients detected almost all high- and low-grade squamous intraepithelial lesions, however, anal cytology alone could not predict the degree of dysplasia. It may be prudent to perform anal bx in all atypical anal cytology. Clear guidelines are needed for screening of a high risk population.

EUROGIN 2014 roadmap: differences in human papillomavirus infection natural history, transmission and human papillomavirus-related cancer incidence by gender and anatomic site of infection. Int J Cancer 2015; 136:2752-60. [PMID: 25043222 PMCID: PMC4297584 DOI: 10.1002/ijc.29082] [Citation(s) in RCA: 199] [Impact Index Per Article: 22.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2014] [Accepted: 07/03/2014] [Indexed: 01/05/2023]
Abstract
Human papillomaviruses (HPVs) cause cancer at multiple anatomic sites in men and women, including cervical, oropharyngeal, anal, vulvar and vaginal cancers in women and oropharyngeal, anal and penile cancers in men. In this EUROGIN 2014 roadmap, differences in HPV-related cancer and infection burden by gender and anatomic site are reviewed. The proportion of cancers attributable to HPV varies by anatomic site, with nearly 100% of cervical, 88% of anal and <50% of lower genital tract and oropharyngeal cancers attributable to HPV, depending on world region and prevalence of tobacco use. Often, mirroring cancer incidence rates, HPV prevalence and infection natural history varies by gender and anatomic site of infection. Oral HPV infection is rare and significantly differs by gender; yet, HPV-related cancer incidence at this site is several-fold higher than at either the anal canal or the penile epithelium. HPV seroprevalence is significantly higher among women compared to men, likely explaining the differences in age-specific HPV prevalence and incidence patterns observed by gender. Correspondingly, among heterosexual partners, HPV transmission appears higher from women to men. More research is needed to characterize HPV natural history at each anatomic site where HPV causes cancer in men and women, information that is critical to inform the basic science of HPV natural history and the development of future infection and cancer prevention efforts.

Abstract
INTRODUCTION Human papillomavirus (HPV) is the commonest sexually transmitted infection worldwide and causes substantial morbidity in both sexes. Most European countries offer HPV vaccination for girls, but vaccine recommendations for boys are warranted. AIMS The aims of this study were to investigate the prevalence of genital HPV, identify parameters that affect the prevalence, and describe the type-specific prevalence among men in Europe. METHODS A systematic review and meta-analysis of the published literature in PubMed and Embase. MAIN OUTCOME MEASURES Genital HPV prevalence and factors influencing prevalence in general and high-risk male populations in Europe. RESULTS We included 31 articles that gave the prevalence of genital HPV DNA among men in northern, southern and western Europe; no studies from eastern Europe were identified. The pooled HPV prevalence among 1,863 men representing the general population (nine studies) was 12.4%, with large heterogeneity between studies (I(2) = 96.3%, P < 0.0001). The pooled HPV prevalence among 6,428 men in the high-risk population (22 studies) was 30.9%, also with substantial heterogeneity (I(2) = 95.6%, P < 0.0001). In unadjusted meta-regression analysis, the HPV prevalence in the general population was significantly higher in studies published after 2000 (28.5%) than in earlier studies (8.8%) (P = 0.0179). In the meta-regression analysis adjusted by publication year, the heterogeneity in the two population groups could not be explained by geographical region, anatomical sampling site, or HPV detection method. HPV16 was the most prevalent high-risk type in both populations. CONCLUSIONS HPV prevalence differs in male general and high-risk populations, but HPV16 and HPV18 are among the most common HPV types detected in both groups. Our findings contribute knowledge that may be useful as a baseline measure before the introduction of HPV vaccination for boys in Europe, and add to understanding of the epidemiology of HPV infection in men.

Establishment and genetic characterization of six unique tumor cell lines as preclinical models for sinonasal squamous cell carcinoma. Sci Rep 2014; 4:4925.

Abstract
Sinonasal squamous cell carcinomas (SCC) are rare tumors, etiologically related to occupational exposure to wood and leather dust. In spite of surgical and radiotherapeutic advances, the 5 year survival is still 30–50%. Therefore, alternative treatment options are needed. We report the establishment and characterization of six unique human sinonasal SCC cell lines, named SCCNC1, 2, 4, 5, 6 and 7. In vitro growth and invasion characteristics were evaluated and genetic profiles were compared to those of the original primary tumors. The population doubling times ranged from 21 to 34 hours. Cell lines SCCNC2 and 7 were highly invasive in matrigel. Five cell lines carried a high number of copy number alterations, including amplifications and homozygous deletions, while one showed only three abnormalities. Sequence analysis revealed three cell lines with TP53 mutation and none with KRAS or BRAF. Overexpression of p53 was observed in five, and of EGFR in four cell lines. None of the cell lines showed strong immunopositivity of p16 or presence of human papilloma virus. In conclusion, we have created six new cell lines that are clinically and genetically representative of sinonasal SCC and that will be a useful tool for the preclinical testing of new therapeutic agents.

Abstract
Purpose Recent studies in Puerto Rico have reported an increasing incidence of anal cancer in Puerto Rican men. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among men attending an STI clinic in Puerto Rico. Methods We conducted a cross-sectional study among 205 men 18 years and older. A comprehensive survey was administered that included a demographic and a behavioral assessment. Separate logistic regression models were performed to determine factors associated with any, high-risk (HR), and multiple anal HPV infection. Results The mean age of the study sample was 38.0±13.5 years. The most common HR types were 58, 51 and 31. Overall, HR anal HPV infection was found in 53.5% of the participants. Multiple HPV types in the anal canal were found in 47.6% of the sample. A third (29.8%) of participants reported being men who had sex with men (MSM). MSM had a significantly higher prevalence of any, HR and multiple HPV infection (p-value<0.05). Separate multivariate logistic regression analyses showed that being MSM was associated with any (OR = 4.5; [95%CI: 1.9–10.7]), HR (OR = 3.4; [95%CI: 1.1–10.3) and multiple anal HPV infection (OR = 3.6; [95%CI: 1.5–9.1). HIV was marginally associated with multiple anal HPV infection in multivariate analysis (OR = 3.3; 95%CI = 1.0–11.0). Conclusions Anal HPV is common among sexually active men attending this STI clinic, with higher likelihood of anal HPV infection among MSM.
