Whitton AF, Knight GL, Marsh EK. Risk factors associated with oral Human Papillomavirus (HPV) prevalence within a young adult population. BMC Public Health 2024; 24:1485. [PMID: 38831431 PMCID: PMC11145846 DOI: 10.1186/s12889-024-18977-x] [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: 12/06/2023] [Accepted: 05/28/2024] [Indexed: 06/05/2024] Open
Abstract
BACKGROUND The prevalence of, and risk factors for, genital Human Papillomavirus (HPV) infections within the young adult population are well-established; the same is not known for oral HPV. This observational study aimed to determine oral HPV prevalence and abundance within a UK young adult population, and examine if sexual practices and established risk factors of oropharyngeal squamous cell carcinomas (OPSCCs) (such as smoking and alcohol consumption) influenced HPV prevalence. METHODS Convenience sampling was used to recruit a small sample of 452 UK-based young adults studying at a higher education (HE) institution to the study; the study was not powered. A highly sensitive real-time PCR HPV screening method was developed for the detection of multiple HPV subtypes from oral swabs. HPV-positive samples were subsequently screened by qPCR for viral subtypes HPV-6, HPV-11, HPV-16, HPV-18. Results were analysed by univariate and multivariate methods and stratified for gender, with lifestyle behaviour data collected via questionnaire. Socio-economic status was not captured within the questionnaire. RESULTS We found a high oral HPV prevalence of 22.79%, with a dominance of high-risk viral type HPV-16 (prevalence 19.12%; abundance average 1.08 × 105 copies/million cells) detected within healthy young adults. Frequent smoking (p = .05), masturbation (p = .029), and engagement in multiple sexual activities (p = .057), were found to be associated with oral HPV prevalence, and HPV-16 prevalence, whilst behaviours traditionally associated with genital HPV were not. CONCLUSIONS Our results strengthen the link between sexual practices and oral HPV transmission. We suggest that young adults should be considered high-risk for the contraction of oral HPV, although acknowledge that this sample of HE students may not be representative of the wider population. We show that high-risk HPV-16 is prevalent in the healthy population, as well as dominating within OPSCC; this study is one of the first to determine the dominance of oral HPV-16 prevalence and abundance within this population, presenting a clear need for greater awareness of oral HPV infections, and the risk factors for HPV-positive OPSCC within young adults.

Abstract
BACKGROUND Cartilage-hair hypoplasia (CHH) is a rare syndromic immunodeficiency with metaphyseal chondrodysplasia and increased risk of malignancy. In this cross-sectional observational study, we examined HPV status and oral microbiome in individuals with CHH. Oral brush samples were collected from 20 individuals with CHH (aged 5-59 years) and 41 controls (1-69 years). Alpha HPVs (43 types) were tested by nested PCR followed by bead-based probe hybridization. Separately, beta-, gamma-, mu- and nu- HPV types were investigated, and a genome-based bacterial microbiome sequencing was performed. RESULTS We found a similar alpha HPV prevalence in individuals with CHH (45%) and controls (36%). The HPV types of individuals with CHH were HPV-16 (25%), 27, 28, and 78, and of controls HPV-3, 16 (21%), 27, and 61. Beta HPV positivity and combined beta/gamma/mu/nu prevalence was detected in 11% and 11% of individuals with CHH and in 5% and 3% of the controls, respectively. Individuals with CHH differed from the controls in bacterial microbiota diversity, richness, and in microbial composition. Individuals with CHH had lower abundance of species Mitsuokella sp000469545, Parascardovia denticolens, Propionibacterium acidifaciens, UMGS1907 sp004151455, Salinicola halophilus, Haemophilus_A paraphrohaemolyticus, Fusobacterium massiliense, and Veillonella parvula, and higher abundance of Slackia exigua. CONCLUSIONS Individuals with CHH exhibit similar prevalence of HPV DNA but different bacterial microbiota on their oral mucosa compared to healthy controls. This may partly explain the previously observed high prevalence of oral diseases in CHH, and regular oral examination is warranted.

A Longitudinal Study Evaluating Sexual Health Outcomes and Prioritization in Patients Undergoing Chemoradiation for Human Papillomavirus-Associated Oropharyngeal Cancer. Int J Radiat Oncol Biol Phys 2024; 118:1018-1028. [PMID: 37865126 DOI: 10.1016/j.ijrobp.2023.10.006] [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: 05/25/2023] [Revised: 10/01/2023] [Accepted: 10/08/2023] [Indexed: 10/23/2023]
Abstract
PURPOSE The primary objectives were to describe the longitudinal course of sexual health in people undergoing curative (chemo)radiation therapy ([C)RT) for human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPVOPSCC) and identify factors associated with higher sexual satisfaction 12 months after (C)RT. METHODS AND MATERIALS Eligible participants from 3 sites were recruited to a prospective observational study between October 2020 and November 2021. Measures of sexual health (22-item European Organization for Research and Treatment of Cancer Sexual Health Questionnaire), treatment outcome priorities (Chicago Priorities Scale), quality of life (30-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire), symptom burden (MD Anderson Symptom Inventory-Head and Neck), emotional distress (Patient-Reported Outcomes Measurement Information System - Anxiety and Depression), and facial appearance and appearance distress (FACE-Q) were administered before, at the end, and 3 and 12 months after (C)RT. RESULTS Of 128 eligible participants, 100 were recruited; sexual health measure data were available for 89 of 98 patients alive at 12 months. Mean sexual satisfaction scores were 51.8 (SD = 26.6) before (C)RT. Mixed model results indicated a clinically significant reduction in sexual satisfaction by the end of (-25.4; 95% CI, -30.7 to -20.2) and 3 months after CRT (-12.2; -17.3 to -7.0) but not 12 months after CRT (-3.8; 95% CI, -9.0 to 1.4). Of 13 treatment outcome priorities, "keeping sexual function" had a median rank of 10 and 9 before and 12 months after (C)RT, respectively; 24% and 26% identified it as a top priority at these times. Cohabiting, having a sexual partner, being sexually active, higher global health status, lower sexual health issues, lower depression, and considering sexual function a top priority were associated with higher sexual satisfaction scores 12 months after (C)RT. CONCLUSIONS Although affected acutely by (C)RT, average sexual satisfaction returned to near pretreatment levels after 12 months. Sexual function is considered a top survivorship priority by approximately one-quarter of patients with HPVOPSCC.

Risk Factors for the Anal and Oral Human Papillomavirus (HPV) Infections among Women with Severe Cervical Lesions: A Prospective Case-Control Study. Biomedicines 2023; 11:3183. [PMID: 38137404 PMCID: PMC10741157 DOI: 10.3390/biomedicines11123183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 11/25/2023] [Accepted: 11/27/2023] [Indexed: 12/24/2023] Open
Abstract
The carcinogenicity of HPV infection in the anogenital and oropharyngeal regions is broadly accepted. The aim of the study was to define risk factors for anal and oral HPV infections in high-risk patients with biopsy-proven severe cervical lesions (CIN2+). Altogether immunocompetent 473 females with CIN2+ were categorized into the study group and another 245 women into the control group. The strongest risk factor for anal HPV infection was the presence of cervical HPV infection (p < 0.001). Furthermore, ten or more lifetime sexual partners (p = 0.013), a sexual non-coital contact with the anal area (p < 0.001), and actively practicing anal-penetrative intercourse (p < 0.001) were significantly associated with anal HPV. A history of genital warts in the woman (p = 0.010) and the presence of genital warts in the male partner (p = 0.029) were found statistically significant for the risk of oral HPV infection. Our data suggest that the presence of HPV infection, especially high-risk genotypes, in one anatomical site poses the greatest risk for HPV infection in another anatomical site. The cervix is the main reservoir of infection, but the risk factors for anal and oral HPV infections are dissimilar according to different anatomical distances and more complex routes of transmission.

Abstract
PURPOSE Several studies have found associations between periodontitis and various types of cancer. Since the site of head and neck cancer (HNC) has contiguity or proximity to the oral cavity, it may be particularly influenced by oral inflammation. This study aimed to determine whether HNC patients have poor oral health as compared to those with other types of cancer. METHODS This study retrospectively examined oral environmental factors including periodontal inflamed surface area (PISA), a new periodontal inflammatory parameter. A total of 1030 cancer patients were divided into the HNC (n = 142) and other cancer (n = 888) groups. Furthermore, the HNC group was divided into high (n = 71) and low (n = 71) PISA subgroups, and independent risk factors affecting a high PISA value were investigated. RESULTS Multivariate logistic regression analysis showed that number of missing teeth (odds ratio 1.72, 95% CI 1.15-2.56, P < 0.01), PISA (odds ratio 1.06, 95% CI 1.03-1.06, P < 0.05), and oral bacterial count (odds ratio 1.02, 95% CI 1.01-1.03, P < 0.01) were independent factors related to HNC. In addition, multivariate logistic regression analysis indicated that current smoker (odds ratio 7.51, 95% CI 1.63-34.71, P < 0.01) and presence of untreated dental caries (odds ratio 3.33, 95% CI 1.23-9.00, P < 0.05) were independent risk factors affecting high PISA values in HNC patients. CONCLUSION HNC patients have higher levels of gingival inflammation and poor oral health as compared to patients with other types of cancer, indicating that prompt oral assessment and an effective oral hygiene management plan are needed at the time of HNC diagnosis.

Abstract
INTRODUCTION Oral lichen planus (OLP) is a chronic inflammatory disorder with cell-induced immunopathological responses and is considered a potential malignancy disorder in the oral cavity. Due to the high prevalence of OLP as well as the potential for malignancy, human papillomaviruses (HPVs) may play an important role in it. Although previous studies have explored the possible relationship between HPV and OLP, the findings have been conflicting and nonconclusive. This study aims to review the studies that investigated HPV-16 and HPV-18 in OLP. METHODS AND MATERIALS The research protocol followed the Preferred Reporting Items for Systematic Reviews (PRISMA2020) checklist. The online databases Pubmed, Scopus, Embase, Google Scholar, and Cochrane were searched using the following individual keywords: "OLP" OR "Oral Lichen Planus" OR "HPV" OR "Human Papillomavirus." The search strategy resulted in the selection of 80 articles. The articles were evaluated, and after duplication removal, 53 abstracts were reviewed, resulting in the selection of 25 studies according to inclusion and exclusion criteria. The risk of bias assessment was done by using the Modified Newcastle-Ottawa quality assessment scale. The overall prevalence of HPV in OLP lesions varied from 2.7% to 70%, depending on the type of diagnostic method used. CONCLUSION Despite the studies conducted on the relationship between OLP and HPV infection, there is still no conclusive evidence that HPV can play a role in the etiopathogenesis of OLP, either in clinical manifestations or in the malignant transformation of lesions.

Abstract
HPV plays a vital role in the development of cervical cancers and oropharyngeal cancers, but it is controversial whether HPV is involved in oral cancer development and to what extent. In this review, the clinical characteristics, diagnosis, treatment, and prognosis of HPV-positive oral cancers are summarized, and the mechanisms of HPV-related oral cancer development are discussed. HPV DNA positivity rates are 20-30% in oral squamous cell carcinoma (OSCC), and HPV16 is the most common high-risk HPV. E6/E7 mRNA positivity rates are 2-6% in OSCC. Detection of both high-risk HPV DNA and E6/E7 mRNA is recommended to determine the presence of active HPV, in agreement with high-risk HPV infection in OSCC. Surgical treatment is the first-line therapy for HPV-positive and -negative oral cancer, but there is no unified view about the prognosis of HPV-positive OSCC patients. HPV16 may play a vital role in malignant transformation in oral epithelial dysplasia, and a model of synergistic carcinogenic impact of HPV and tobacco smoking is predicted. Additionally, it is hypothesized that there are different HPV-associated oral cancers, such as integrated HPV DNA-positive OSCC with stable E6/E7 expression and episomal HPV DNA-positive OSCC. In summary, the role of HPV in oral carcinogenesis seems to be limited because of the low E6/E7 positivity in OSCCs; however, episomal HPV DNA may play a vital role in the malignant transformation of HPV-positive oral premalignant lesions. Further investigation is required to promote new insights into the role of episomal HPV DNA in oral carcinogenesis.

Abstract
The recent increase in high-risk human papillomavirus (HR-HPV)-associated oral and oropharyngeal cancers has gained considerable importance due to their distinct clinical and molecular characteristics. However, the natural history of oral HPV from acquisition to persistence and malignant transformation is still unclear. The global prevalence of oral HPV infection in healthy individuals ranges from 0.67% to 35%, while 31%-38.5% in head and neck cancer (HNC). The persistence rate of oral HR-HPV infection is 5.5% -12.8% globally. India has the highest HNC burden due to apparent differences in predisposing factors compared with the West. The prevalence of oral HPV in healthy individuals and its contribution to HNC is less evident in Indian studies. HR-HPV-associated HNC in this region accounts for 26%, with an active infection in 8%-15% of these tumors. There is a lack of concordance in the expression of p16 as a surrogate marker for HPV detection in HNC because of differences in behavioral risk factors. Due to a lack of evidence, treatment de-escalation cannot be implemented despite the improved outcome of HPV-associated oropharyngeal cancers. This review critically analyzes the existing literature on the dynamics of oral HPV infection and HPV-associated HNC, identifying potential avenues for future research. A better understanding of the oncogenic role of HR-HPV in HNC will help to formulate novel therapeutic approaches and is expected to have a significant public health impact as preventive strategies can be implemented.

Abstract
BACKGROUND Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Although the efficacy of the HPV vaccine in preventing the development of cervical pre-malignant lesions has been well demonstrated, the efficacy of the HPV vaccine in preventing HPV infection in the upper respiratory tract has been poorly studied. METHODS In the context of the IARC cohort study of two versus three doses of HPV vaccine in India, we compared the HPV type prevalence in the oral cavity of women vaccinated with three doses, two doses, or a single dose of quadrivalent HPV vaccine with that of unvaccinated women. A total of 997 oral samples, from 818 vaccinated women and 179 unvaccinated women, were collected at three study sites. All the participants were sexually active at the time of sample collection. RESULTS The age-standardized proportion (ASP) of HPV16/18 infections was 2.0 % (95 % CI, 1.0-3.0 %) in vaccinated women and 4.2 % (95 % CI, 1.2-7.2 %) in unvaccinated women. HPV16 was detected in 3.5 % of single-dose recipients, 1.2 % of two-dose recipients (days 1 and 180), and 1.5 % of three-dose recipients (days 1, 60, and 180), whereas 3.3 % of the unvaccinated women tested positive for HPV16. The same trend was observed for HPV18. DISCUSSION Our findings agree with those of previous studies on the efficacy of HPV vaccination in reducing oral HPV infections and provide indications that a single vaccine dose may be less efficient than two or three doses in preventing oral HPV infection.

Passive Immunization with a Single Monoclonal Neutralizing Antibody Protects against Cutaneous and Mucosal Mouse Papillomavirus Infections. J Virol 2022; 96:e0070322.

Abstract
We have established a mouse papillomavirus (MmuPV1) model that induces both cutaneous and mucosal infections and cancers. In the current study, we use this model to test our hypothesis that passive immunization using a single neutralizing monoclonal antibody can protect both cutaneous and mucosal sites at different time points after viral inoculation. We conducted a series of experiments involving the administration of either a neutralizing monoclonal antibody, MPV.A4, or control monoclonal antibodies to both outbred and inbred athymic mice. Three clinically relevant mucosal sites (lower genital tract for females and anus and tongue for both males and females) and two cutaneous sites (muzzle and tail) were tested. At the termination of the experiments, all tested tissues were harvested for virological analyses. Significantly lower levels of viral signals were detected in the MPV.A4-treated female mice up to 6 h post-viral inoculation compared to those in the isotype control. Interestingly, males displayed partial protection when they received MPV.A4 at the time of viral inoculation, even though they were completely protected when receiving MPV.A4 at 24 h before viral inoculation. We detected MPV.A4 in the blood starting at 1 h and up to 8 weeks postadministration in some mice. Parallel to these in vivo studies, we conducted in vitro neutralization using a mouse keratinocyte cell line and observed complete neutralization up to 8 h post-viral inoculation. Thus, passive immunization with a monoclonal neutralizing antibody can protect against papillomavirus infection at both cutaneous and mucosal sites and is time dependent. IMPORTANCE This is the first study testing a single monoclonal neutralizing antibody (MPV.A4) by passive immunization against papillomavirus infections at both cutaneous and mucosal sites in the same host in the mouse papillomavirus model. We demonstrated that MPV.A4 administered before viral inoculation can protect both male and female athymic mice against MmuPV1 infections at cutaneous and mucosal sites. MPV.A4 also offers partial protection at 6 h post-viral inoculation in female mice. MPV.A4 can be detected in the blood from 1 h to 8 weeks after intraperitoneal (i.p.) injection. Interestingly, males were only partially protected when they received MPV.A4 at the time of viral inoculation. The failed protection in males was due to the absence of neutralizing MPV.A4 at the infected sites. Our findings suggest passive immunization with a single monoclonal neutralizing antibody can protect against diverse papillomavirus infections in a time-dependent manner in mice.

Abstract
Human papillomavirus (HPV) is associated with both benign lesions and with neoplastic diseases, such as oropharyngeal cancer. Due to the increasing occurrence of these neoplasms on a global scale, it seems important to estimate the risk factors in the population. So far, data on the presence of oral HPV in the European population are scarce. Oral HPV was detected in 53 out of 461 healthy subjects (11.5%) in south-eastern Poland. Among the most common oncogenic types, HPV 16 was reported in four subjects (0.87%) and HPV 18 in three subjects (0.65%). Another high-risk type, HPV 45, was detected in nine subjects (1.95%). Low risk types (HPV 6, 11, 54) were detected in 25 cases, which constituted 5.4% of all tested samples. In adults and children, statistically more HPV positive cases have been reported in males than in females. A positive relationship was demonstrated between age and the amount of positive oral HPV. The presence of HPV was statistically more frequent in the population living in urban rather than in rural areas in all studied age groups (p < 0.05).

Abstract
Abstract
Introduction
In recent years, interest in human papillomavirus infections as a causative factor in epithelial cancer development has grown. Literature indicates that HPV involvement in malignant transformations in oral mucosa can vary significantly, from 0 up to 87%. The aim of our study was to detect the prevalence of salivary HPV infection among generally healthy adults.
Materials and Methods
The examination involved 139 patients, from whom 139 whole, 1.5ml saliva samples were obtained. HPV DNA was detected by the nested PCR technique. To visualize the PCR products electrophoresis reactions were carried out.
Results
Sample analysis showed that DNA for HPV was detected in 14 patients: 11 positive results were obtained from men, and 3 from women. This yields a high infection rate: 10.07%.
Conclusions
The HPV prevalence in the male group was more than twice as high as in the female group. Also, subclinical oral HPV infection was detected more frequently in young (19–39 years old) and older (=>60 years old) adults.

Abstract
Statement of the Problem Oral health status has been suggested as one of the possible risk factors for oral human papillomavirus (OHPV) infection. There is inconsistent evidence concerning its relationship with the presence of OHPV. Purpose This study aimed to compare oral health status between two groups of patients with and without OHPV infection. Materials and Method This cross-sectional study was performed on 272 oral rinse samples, collected from our previous study population. After signing the written informed consents, the oral examination was performed to determine some clinical parameters of oral health status including periodontal disease status, oral hygiene status, decayed, missing, and filled teeth (DMFT) of participants. Next, viral deoxyribonucleic acid (DNA) extraction, polymerase chain reaction (PCR), and HPV genotyping tests were performed on the samples. Results OHPV DNA was detected in a total 31 (11.40%) samples that were considered as OHPV+ group. None of the determined clinical parameters of oral health status was significantly different between OHPV+ and OHPV DNA negative (OHPV-) groups (p> 0.05). Conclusion The findings of the current study did not indicate a significant association between oral health status and OHPV. Further studies with larger sample size are recommended to reach a definite conclusion.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Oral cancers are found to have high risk in South Central Asia due to exposure of various risk factors. Euphoria longana Lam. (EL) has been traditionally used to relieve insomnia, prevent amnesia, and treat palpitation. In addition, EL has been reported to have anti-inflammatory, anti-cancer, and antioxidant activities. The investigation was aimed to evaluate the mechanism of action and antitumor activity of polyphenol-rich EL seeds extract against oral cancer induced by 4-Nitroquinoline-1-oxide (4-NQO). MATERIALS AND METHODS Seven groups of Sprague-Dawley rats were formulated: normal animals, oral cancer induced with 4-NQO, EL-treated normal control, EL-treated disease control from 0-day, EL-treated disease control from 60 days, 5-fluorouracil (5-FU)-treated disease control from day 60, and combined EL- and 5-FU-treated disease control animals from day 60. The animal tongue was smeared with 0.5% 4-NQO at frequency of thrice a week for 12 weeks to induce oral cancer. At the end of treatment, excised tongues were used for biochemical and tumour-specific parameters along with histopathology assessment. RESULTS Treatment with EL, 5-FU, and combination of both in diseased animals exhibited significant improvement in interleukin-6, vascular endothelial growth factor (VEGF), and Transforming growth factor beta (TGF-β) levels, antioxidant status together with histoarchitecture of the tongue tissue. In addition, the combination of both was slightly more effective than EL and 5-FU alone. CONCLUSION Our data suggest antitumor activity of Euphoria longana Lam. Extract against 4-NQO induced oral cancer in rats, which could be attributed to alteration in the VEGF and TGF-β signaling axis.

Abstract
Oral infection by Human Papillomavirus (HPV) has recently gained great attention because of its involvement in the development of a subset of head and neck squamous cell carcinoma. The role of specific Alpha-HPVs in this regard has been well established, whereas the contribution of other genera is under investigation. Despite their traditional classification as “cutaneous” types, Beta and Gamma HPVs are frequently detected in oral samples. Due to the lack of a standardized protocol, a large variety of methodologies have been used for oral sample collection, DNA extraction, HPV detection and genotyping. Laboratory procedures influence the evaluation of oral HPV prevalence, which largely varies also according to the population characteristics, e.g., age, gender, sexual behavior, Human Immunodeficiency Virus (HIV) status. Nevertheless, oral infection by Beta and Gamma HPVs seems to be even more common than Alpha-HPVs. The latter is 5–7% in the general population, and increases up to 30% approximately in HIV-infected men who have sex with men. Despite major advances in the evaluation of oral HPV prevalence, its natural history is still little understood, especially for Beta and Gamma HPVs. The latest technologies, such as Next Generation Sequencing (NGS), can be exploited to gain new insights into oral HPV, and to improve the identification of novel HPV types.

Abstract
OBJECTIVES The present study aimed to evaluate human papillomavirus (HPV) occurrence in sinonasal inverted papilloma (SNIP), and to assess factors associated with HPV positivity and SNIP recurrence. STUDY DESIGN Prospective study. METHODS We prospectively collected clinical data and fresh tissue specimens from 90 consecutive patients treated for SNIP at Helsinki University Hospital, between 2015 and 2019. Fourteen patients with recurrent SNIP underwent repeated tumor sampling. All tissue specimens were analyzed for the presence of HPV. Factors associated with SNIP recurrence and HPV positivity were assessed. RESULTS Among 107 SNIP specimens, 14 (13.1%) were positive for low-risk HPV and 6 (5.6%) were positive for high-risk HPV. HPV positivity was associated with an increased risk of recurrence (P = .004). Smoking was significantly associated with HPV positivity in SNIP (P = .01), but a history of HPV-related diseases or patient sexual habits did not correlate with HPV positivity. The recurrence rate was lower among patients with SNIP that underwent an attachment-oriented resection, compared to patients treated without attachment-oriented resections (78.6% vs 25.8%, P < .001). CONCLUSIONS The risk of SNIP recurrence was highly associated with 1) HPV positivity and 2) surgery without an attachment-oriented resection. Oncogenic HPV was rare in SNIP.

Abstract
Although oral cytology using Papanicolaou stain is useful for the early detection of oral premalignant lesions and squamous cell carcinoma (SCC) in people, little work has been conducted on this topic in veterinary medicine. This paper describes the features of oral cytology using Papanicolaou stain and immunocytochemistry on liquid-based cytology slides in a case of oral SCC in an Indo-Pacific bottlenose dolphin (Tursiops aduncus). In this case, dysplastic cells with koilocyte-like changes and SCC cells were identified using the Papanicolaou stain. These cells were positive for p53 using an immunocytochemistry analysis. A cytologic diagnosis of SCC was made. We believe that the early detection of premalignant oral lesions and SCC in dolphins can be significantly improved with cytology using liquid-based cytology, Papanicolaou staining, and immunocytochemistry.

Abstract
The epidemic increase in the incidence of Human Papilloma Virus (HPV) related Oropharyngeal Squamous Cell Carcinomas (OPSCCs) in several countries worldwide represents a significant public health concern. Although gender neutral HPV vaccination programmes are expected to cause a reduction in the incidence rates of OPSCCs, these effects will not be evident in the foreseeable future. Secondary prevention strategies are currently not feasible due to an incomplete understanding of the natural history of oral HPV infections in OPSCCs. The key parameters that govern natural history models remain largely ill-defined for HPV related OPSCCs and cannot be easily inferred from experimental data. Mathematical models have been used to estimate some of these ill-defined parameters in cervical cancer, another HPV related cancer leading to successful implementation of cancer prevention strategies. We outline a "double-Bayesian" mathematical modelling approach, whereby, a Bayesian machine learning model first estimates the probability of an individual having an oral HPV infection, given OPSCC and other covariate information. The model is then inverted using Bayes' theorem to reverse the probability relationship. We use data from the Surveillance, Epidemiology, and End Results (SEER) cancer registry, SEER Head and Neck with HPV Database and the National Health and Nutrition Examination Surveys (NHANES), representing the adult population in the United States to derive our model. The model contains 8,106 OPSCC patients of which 73.0% had an oral HPV infection. When stratified by age, sex, marital status and race/ethnicity, the model estimated a higher conditional probability for developing OPSCCs given an oral HPV infection in non-Hispanic White males and females compared to other races/ethnicities. The proposed Bayesian model represents a proof-of-concept of a natural history model of HPV driven OPSCCs and outlines a strategy for estimating the conditional probability of an individual's risk of developing OPSCC following an oral HPV infection.

Abstract
Aim: This study analyses the prevalence, risk factors and knowledge levels for oral human papillomavirus (HPV) infection in healthy university students. Materials & methods: A questionnaire was distributed to 452 participants. Also, oral-rinsed samples were collected for molecular screening and genotyping studies by using validated protocols. Results: The prevalence of HPV was 0.7% (HPV type 72var [0.5%; n = 2] and HPV type 13 [0.2%; n = 1]). Male circumcision and age of first sexual experience were the significant factors associated with oral HPV positivity. Several factors found to be predictors for HPV positivity including not being vaccinated. Conclusion: Here, the prevalence of oral HPV infection was low among a healthy sample pool. Further studies are suggested to clarify relations between the infection and risk factors.

Abstract
The Human Papilloma Virus (HPV) is an oncogenic virus which is associated with the development of head and neck squamous cell carcinoma (HNSCC), predominantly within the oropharynx. Approximately 25% of oropharyngeal squamous cell carcinoma (OPSCC) cases worldwide are attributable to HPV infection, with an estimated 65% in the United States. Transmission is via exposure during sexual contact, with distinctive anatomical features of the tonsils providing this organ with a predilection for infection by HPV. No premalignant lesion is identifiable on clinical examination, thus no comparative histological features to denote the stages of carcinogenesis for HPV driven HNSCC are identifiable. This is in contrast to HPV-driven cervical carcinoma, making screening a challenge for the head and neck region. However, HPV proffers a favorable prognosis in the head and neck region, with better overall survival rates in contrast to its HPV negative counterparts. This has resulted in extensive research into de-intensifying therapies aiming to minimize the morbidity induced by standard concurrent chemo-radiotherapy without compromising efficacy. Despite the favorable prognosis, cases of recurrence and/or metastasis of HPV positive HNSCC do occur, and are linked with poor outcomes. HPV 16 is the most frequent genotype identified in HNSCC, yet there is limited research to date studying the impact of other HPV genotype with respect to overall survival. A similar situation pertains to genetic aberrations associated in those with HPV positive HNSCC who recur, with only four published studies to date. Somatic mutations in TSC2, BRIP1, NBN, TACC3, NFE2l2, STK11, HRAS, PIK3R1, TP63, and FAT1 have been identified in recurrent HPV positive OPSCC. Finding alternative therapeutic strategies for this young cohort may depend on upfront identification of HPV genotypes and mutations which are linked with worse outcomes, thus ensuring appropriate stratification of treatment regimens.

Abstract
Human papillomavirus (HPV) is a small DNA virus that infects the basal keratinocytes of squamous epithelium in the skin, and in the oral and genital mucosa. Smoking and sexual behavior have been recognized as significant risk factors for oral HPV infection. In the present review, the findings of recent studies of oral HPV infection in relation to periodontitis are discussed, as well as periodontopathic bacteria and periodontal herpes virus. Previous research suggests that HPV localizes to the inflammatory periodontal tissue. Inflammatory periodontal pockets may thus act as a reservoir for HPV. The interactions between HPV and periodontopathic bacteria remain unclear, but it is hypothesized that oral HPV infection may be related to a characteristic oral microbiome. Smoking is associated with HPV and periodontitis, as smoking induces destruction of periodontal tissue and suppresses the host defense, allowing HPV to infect periodontal tissue. Carcinogenic HPV and periodontitis may lead to the development of oral cavity cancer. However, oral HPV E6/E7 expression (transcriptionally active HPV) has not yet been fully investigated in patients with periodontitis. Collectively, the evidence suggests that oral HPV prevalence may be associated with periodontitis. The effect of clinical factors (age, sex, smoking, immunosuppressive condition and vaccination) on oral HPV DNA prevalence should be considered when clarifying the relationship between oral HPV and periodontitis. Additionally, the sampling method should be carefully chosen to directly detect HPV DNA in periodontal tissues.

Oral and laryngeal HPV infection: Incidence, prevalence and risk factors, with special regard to concurrent infection in head, neck and genitals. Vaccine 2021; 39:2344-2350. [PMID: 33812740 DOI: 10.1016/j.vaccine.2021.03.047] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/09/2021] [Accepted: 03/10/2021] [Indexed: 12/20/2022]
Abstract
This review focuses on the importance of oral and laryngeal HPV infection which is present in majority of sexually active individuals at least once in their lifetime. Despite testing, still little is known about prevalence rates, determinants and, especially, the concurrent HPV infection in head and neck, and genitals. The purpose of this review is to clarify some issues of oral HPV incidence, prevalence, and to demonstrate the difficulties in identification of asymptomatic oral HPV carriers. The main premise to take up this topic is the high and still increasing risk for development of oropharyngeal cancer, and potential benefit from screening strategies, education programs and HPV vaccination. Transmission of HPV to the oral cavity and oropharynx is hypothesized to occur mainly through sexual contact. The exposure of oropharyngeal mucosa to HPV infection with consequence of increased risk for oropharyngeal carcinoma depends on specific sexual behavior. Male gender, older age, race or ethnicity, oral hygiene and current cigarette smoking are independently associated with any prevalent oral HPV infection.

Does HPV Subtype Predict Outcomes in Head and Neck Cancers? Int J Otolaryngol 2021; 2021:6672373.

Abstract
Background Recently, reanalysis of The Cancer Genome Atlas study demonstrated that human papillomavirus (HPV) genotypes in head and neck cancers other than HPV-16 have inferior survival to HPV-16-positive tumors. We aimed to examine the association of HPV subtypes and survival in a large cohort of patient samples from our institution. Methods Fresh frozen primary site biopsy samples were collected either in clinic or at the time of surgery. Patient demographic, staging, and survival data were also collected. Tumors were tested for HPV subtypes by quantitative polymerase chain reaction (qPCR). Univariable and multivariable analyses were performed using Cox proportional hazards regression. Results 280 patient biopsy samples were collected between 2011 and 2017. Mean ± standard deviation (SD) age was 61.9 ± 11.1 years and most patients (78%) were male. The majority of cancers were of the oral cavity (60%) or oropharynx (25%) and 30% had HPV-positive disease. Median follow-up was 3.76 years and 96/280 patients (34%) developed recurrences. Patients with p16-positive versus negative disease had significantly improved 5-year overall survival (OS, 77.6% vs. 53.3%; p=0.009) and progression-free survival (PFS, 67.3% vs. 41.0%, p=0.006). Similarly improved 5-year OS and PFS were observed for patients with HPV-positive versus negative disease (65.0% vs. 55.0%, p=0.084; 53.3% vs. 43.2%, p=0.072, resp.). Patients with HPV-16 compared to other HPV diseases had worse 5-year OS and PFS (62.1% vs. 88.9%, p=0.273; 49.0% vs. 88.9%, p=0.081, resp.). Conclusions In contrast to the data derived from The Cancer Genome Atlas, patients with HPV-16 tumors trended towards decreased PFS and OS compared with tumors driven by other HPV genotypes. Further larger multi-institutional studies are necessary to understand the relationship between other HPV genotypes and survival in head and neck squamous cell carcinomas.

Abstract
The oral cancer constitutes 48% of head and neck cancer cases. Ninety percent of oral cancer cases are histologically diagnosed as oral squamous cell carcinomas (OSCCs). Despite new management strategies, the 5-year survival rate of oral cancer is still below 50% in most countries. Head and neck cancers are heterogeneous tumors, and this characteristic of them provides a challenge to treatment plan. Due to the poor outcomes in oral cancer, prevention is a necessity. In this review, a relevant English Literature search in PubMed, ScienceDirect, and Google Scholar from 2000 to mid-2018 was performed. All published articles related to oral cancer and its prevention were included. The risk factors of oral cancer and strategies of oral cancer prevention will be discussed.

Association of oral HPV16 infection with periodontal inflammation and the oral microbiome in older women. Exp Ther Med 2020; 21:167.

Abstract
The present preliminary study aimed to investigate the association between oral human papillomavirus type 16 (HPV16) DNA prevalence and periodontal inflammation in older women. The association between oral HPV16 infection and oral health status has not been fully elucidated in older Japanese women. The present study investigated older women aged ≥60 years who visited Hiroshima University Hospital. The present study excluded subjects with clinical factors affecting HPV infection, such as current smoking, oral cancer and pre-malignant lesions, and immunodeficiency. Finally, 46 female patients (mean age, 74.6 years) were analyzed. Quantitative PCR analysis was performed to detect HPV16 DNA in oral rinse samples. A total of 4 participants (8.7%) were HPV16 DNA positive. There was a significant association between the HPV16 DNA positivity rate and bleeding on probing (P=0.03). Additionally, Prevotella intermedia positive cases exhibited a significantly higher HPV16 DNA positivity rate than negative cases (33.3 vs 3.8%). Furthermore, analysis of 16S ribosomal RNA in bacterial flora was performed to examine microbiome diversity in participants with ≥6 mm periodontal pockets and bleeding on probing. Importantly, the average percentage of Porphyromonas was significantly higher in HPV16 DNA positive cases compared with in HPV16 DNA negative cases (5.57 vs. 1.44%). By contrast, the average percentage of Veillonella was significantly lower in HPV16 DNA positive cases than in HPV16 DNA negative cases (2.43 vs. 8.51%). Prevotella was also lower in HPV16 DNA positive cases than in HPV16 DNA negative cases (4.0 vs. 8.23%). These results indicated that people with both deep periodontal pocket inflammation and oral HPV16 infection may not have Prevotella- or Veillonella-dominant oral microbiomes, and their microbiomes may exhibit their own distinctive characteristics. In conclusion, the results suggested that oral HPV16 infection may be associated with periodontal inflammation in older Japanese women. Further research is required to clarify the detailed association between oral HPV infection and the oral microbiome.

Abstract
Human papillomavirus (HPV) infection has implicated in the development of some of the oral/oropharyngeal cancers. However, controversy still exists regarding the prevalence of oral HPV (OHPV) and its risk factors. This study aimed to determine the prevalence and variables of OHPV infection in a healthy Iranian population. This study evaluated 300 oral rinse samples. Following the oral and dental examination of participants and filling out a self-administered questionnaire; samples collected by swishing and gargling 0.09% saline. The viral DNA extraction, polymerase chain reaction and HPV genotyping then performed. Prevalence of OHPV DNA/OHPV+ infection and OHPV genotypes was 12% and 1% (two cases of HPV6 and one case of HPV53), respectively. Comparison of variables between OHPV+ and OHPV- groups revealed that only income (P = .045), number of cigarettes smoked per day (P = .002), and number of teeth in the mouth (P = .005) were significantly different between the two groups. In conclusion, prevalence of OHPV+ infection and its genotypes were very low in our healthy Iranian population, and its association was not significant with the majority of suggested risk factors. Further studies with a larger sample size are recommended to determine OHPV infection risk factors.

Abstract
OBJECTIVE This study aimed to evaluate the incidence of and factors associated with persistence and clearance of oral human papillomavirus (HPV) infections. METHOD A prospective cohort study invited 458 subjects (231 HPV-positive and 227 HPV-negative at baseline) to attend follow-ups at 12 months. Those 231 HPV-positive subjects and 10 new infections were invited to reassessment at 24 months. We used next-gen sequencing for detection and genotyping of HPV. RESULTS α-HPV infections showed higher persistence rates than β/γ-HPV (22.7% vs 9.2% at 12 months [P < .05], 10.6% vs 6.8% at 24 months [P = .30]). Clearance rates of α-HPV were lower than β/γ-HPV at 12 months (31.8% vs 45.1%; P = .05) and higher at 24 months (7.6% vs 4.8%; P = .36). Persistence of β/γ-HPV was positively associated with males (crude odds ratio [COR] = 3.8, 95% confidence interval [CI] = 1.3-11.2), elderly (51-65 vs 16-50 years; COR = 5.1, 95% CI = 1.2-22.3), and smoking (COR = 4.3, 95% CI = 1.9-9.6). Drinking (COR = 0.5, 95% CI = 0.3-0.9), handwashing less than 90% of times before meals (COR = 0.6, 95% CI = 0.3-0.9), and using public bath more than once per month (COR = 0.5, 95% CI = 0.2-0.9) were risk factors hindering β/γ-HPV clearance. CONCLUSIONS This study identified factors associated with persistence and clearance of oral HPV infections among Chinese. Studies on other ethnogeographic groups may further inform prevention strategies of oral HPV infection and immunization programmes.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is associated with oropharyngeal cancers. The Centers for Disease Control and Prevention (CDC) estimate that >15,000 new cases of HPV-associated oropharyngeal cancers are diagnosed in the United States annually. We evaluated an association between HPV vaccination and dental visits in the previous year. METHODS Data were analyzed from the 2012, 2014, and 2016 Massachusetts Behavioral Risk Factor Surveillance System (MA-BRFSS) datasets. We created four categories of exposures to healthcare services in the past 12 months: a) both medical and dental visits, b) medical visit only, c) dental visit only, d) neither. Outcomes were HPV vaccination ever or influenza vaccination within the past 12 months. Logistic regression, controlled for race and education, was used to measure the association between medical/dental visits and vaccination status. Separate models were generated by sex. RESULTS Crude and adjusted odds ratio of influenza and HPV vaccination were highest among males and females with both medical and dental visits. Women with both medical and dental provider visits had 3.7 times higher odds of being vaccinated for influenza and 1.7 times higher odds of being vaccinated for HPV. There were no differences in crude or adjusted odds among both males and females if the type of healthcare visits were only medical or only dental. CONCLUSION No difference in association between vaccination and medical or dental healthcare exposures suggests that oral health professionals might partner in promotion of positive health behaviors, including HPV vaccination. The type of provider did not affect the outcome as per this study.

Tobacco exposure as a major modifier of oncologic outcomes in human papillomavirus (HPV) associated oropharyngeal squamous cell carcinoma. BMC Cancer 2020; 20:912.

Abstract
Background The incidence of oropharyngeal squamous cell carcinoma (OPSCC) in the US is rapidly increasing, driven largely by the epidemic of human papillomavirus (HPV)-mediated OPSCC. Although survival for patients with HPV mediated OPSCC (HPV+ OPSCC) is generally better than that of patients with non-virally mediated OPSCC, this effect is not uniform. We hypothesized that tobacco exposure remains a critical modifier of survival for HPV+ OPSCC patients. Methods We conducted a retrospective analysis of 611 OPSCC patients with concordant p16 and HPV testing treated at a single institute (2002–2013). Survival analysis was performed using Kaplan-Meier analysis and Cox regression. Recursive partitioning analysis (RPA) was used to define tobacco exposure associated with survival (p < 0.05). Results Tobacco exposure impacted overall survival (OS) for HPV+ patients on univariate and multivariate analysis (p = 0.002, p = 0.003 respectively). RPA identified 30 pack-years (PY) as a threshold at which survival became significantly worse in HPV+ patients. OS and disease-free survival (DFS) for HPV+ > 30 PY patients didn’t differ significantly from HPV- patients (p = 0.72, p = 0.27, respectively). HPV+ > 30 PY patients had substantially lower 5-year OS when compared to their ≤30 PYs counterparts: 78.4% vs 91.6%; p = 0.03, 76% vs 88.3%; p = 0.07, and 52.3% vs 74%; p = 0.05, for stages I, II, and III (AJCC 8th Edition Manual), respectively. Conclusions Tobacco exposure can eliminate the survival benefit associated with HPV+ status in OPSCC patients. Until this effect can be clearly quantified using prospective datasets, de-escalation of treatment for HPV + OPSCC smokers should be avoided.

J Public Health (Oxf) 2020; 43:e610-e619. [PMID: 32915228 DOI: 10.1093/pubmed/fdaa156] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 07/12/2020] [Accepted: 08/10/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The incidence of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCCs) is increasing globally. Common oral conditions such as periodontitis may contribute. We undertook a meta-analysis to quantify the association between periodontitis, oral HPV and OPSCCs. METHODS Multiple electronic databases were searched until 12 February 2020. Studies conducted in males and/or females aged ≥ 18 years that examined periodontitis, periodontal procedures, oral HPV infection, and where possible, oral cancers, were eligible. Meta-analyses were conducted and the GRADE approach was used to examine the quality of evidence. RESULTS Of 2709 studies identified, 13 met the eligibility criteria. Five studies could be included in the meta-analyses. There was no significant increase in the odds of high-risk oral HPV infection among individuals with confirmed periodontitis (odds ratio 4.71, 95% confidence interval 0.57-38.97). Individuals with periodontitis had a 3.65 times higher odds of having any type of oral HPV infection compared with those without periodontitis (95% confidence interval 1.67-8.01). The overall body of evidence was rated as low to very-low certainty. CONCLUSION Meta-analysis confirms there is a positive association between periodontitis and oral HPV infection, although the overall quality of this evidence is low. Evidence for an association between periodontitis and high-risk oral HPV infection is inconclusive.

Abstract
Incidence of human papillomavirus (HPV) attributable oropharyngeal cancers (OPCs) has been increasing globally, especially among men in high-income countries. There is a lack of studies comparing oral HPV prevalence by age and country among healthy men. The purpose of our study was to assess oral HPV prevalence by country and age. Participants of the HPV Infection in Men Study (HIM), a cohort of 3,098 healthy men from São Paulo, Brazil, Cuernavaca, Mexico and Tampa, USA, were studied. Oral HPV prevalence and type distribution were assessed using the SPF10 PCR-DEIA-LiPA25 system. The prevalence of any HPV in Brazil, Mexico and the US was 8.7% (95% CI: 7.1%, 10.4%), 10.0% (95% CI: 8.3%, 12.1%) and 7.6% (95% CI: 5.9%, 9.5%), respectively, while the prevalence of high-risk HPV was 5.3% (95% CI: 4.1%, 6.7%), 7.3% (95% CI: 5.7%, 9.0%) and 5.4% (95% CI: 4.0%, 7.0%), respectively. No significant differences in prevalence of grouped HPV types were observed by country despite significant differences in sexual behaviors. However, the age-specific prevalence of oral HPV differed by country. Brazilian (6.0% [95% CI: 3.4%, 9.7%]) and Mexican (9.2% [95% CI: 5.6%, 14.0%]) participants had peak high-risk HPV prevalence among men aged 41-50 years whereas the US participants had peak prevalence at ages 31-40 years (11.0% [95% CI: 6.4%, 17.3%]). In conclusion, oral HPV prevalence was low with no difference in overall prevalence observed by country. Factors associated with the differences in oral HPV age-patterning by country and sexual orientation require further study.

Prevalence of Human Papillomavirus Infection in the Head and Neck Area of Patients After Kidney Transplantation Treated With Immunosuppressive Therapy. Transplant Proc 2020; 52:2388-2393.

Abstract
The introduction of new and stronger immunosuppressive agents has significantly improved the overall survival rate of patients with transplanted organs; however, prolonged use of immunosuppressive agents has led to severe complications, such as the development of de novo malignant cancers. The incidence of malignant tumors is 3 to 5 times greater among renal transplant recipients than that of the overall population. Traditional neoplasms of the head and neck region are associated with the addiction to smoking and drinking alcohol. However, recent studies indicate that cancers of the throat, tongue, and tonsils are primarily associated with the human papillomavirus (HPV) infection. At present, approximately 25% of the head and neck squamous cell carcinomas are associated with HPV infection. Therefore, we aimed to determine the incidence of oropharyngeal HPV infection in recipients with kidney transplants treated with immunosuppressive therapy and to determine the factors that may favor the contraction of infectious diseases. Furthermore, we considered the purpose of vaccination against HPV among transplant recipients. A total of 32 recipients with kidney transplants were included in this study. Medical history was obtained and a throat swab was collected from each patient. The presence of the HPV DNA in the throat was determined using the GP5+/GP6+ primers. According to our results, 28% of the recipients with kidney transplants were positive for oropharyngeal HPV infection. In addition, among the investigated risk factors, early commencement of the sexual life (below the age of 16 years) was significantly correlated with the development of oropharyngeal HPV infection.

Abstract
Background Differences in oral human papillomavirus (HPV) prevalence and contrasts in HPV-attributable fractions (AFs) in oropharyngeal cancer (OPC) have not been evaluated in depth. Methods A systematic review was performed to identify studies in which at least 50 healthy individuals were tested for oral HPV infection. Information on sex, age, tobacco/alcohol consumption, sex practices, specimen collection, HPV detection, and population type was extracted. Prevalences were pooled using random-effects models for meta-analyses of binomial data. Correlations were assessed by the Spearman test. Results Forty-eight reports comprising 28 544 individuals fulfilled inclusion criteria. Global oral HPV prevalence was 4.9%. Estimates were highest in Europe, although regional differences were not statistically significant. HPV16 prevalence was 1.0% globally, and regional differences became statistically significant. A lifetime history of >6 sex partners showed a higher risk of oral HPV infection. The age-specific HPV distribution revealed a prevalence of ≥5% over 40 years of age and a lower prevalence at younger ages. There was no association between oral HPV prevalence and HPV-AFs or age-standardized rates (ASRs) of OPC, genital HPV in healthy women, or tobacco use. Conclusions Differences in HPV-AFs or ASRs of OPC cannot be explained by differences in the prevalence of oral HPV infection across healthy populations. Consistent research on determinants of oral HPV prevalence, acquisition, clearance, and persistence is warranted.

Abstract
Human papillomavirus (HPV) infection and tobacco smoking are well-known risk factors for head and neck cancers (HNC). Although an effect modification between oral HPV infection and tobacco smoking may exist, evidence is lacking on how they interact temporally. We investigated the latency and life course effects of tobacco smoking on risk of HNC among HPV-positive (HPV+ve ) and negative (HPV-ve ) individuals. We used data from 631 ever-smoker participants of a hospital-based case-control study conducted in four major hospitals in Montréal, Canada. Cases (n = 320), incident, histologically confirmed, primary squamous cell carcinomas, were frequency-matched to controls (n = 311) by age and sex. Sociodemographic and behavioral factors (e.g., tobacco and alcohol use and sexual history) were collected using a structured interview applying a life grid technique. Oral exfoliated cells were used for HPV DNA detection and genotyping. Latency effects were estimated flexibly using a Bayesian relevant exposure model and further extended with a life course approach. Retrospective smoking trajectories for HPV+ve cases and controls had similar shapes. Exposure to tobacco smoking even 40 years before diagnosis was associated with an increased HNC risk among both HPV+ve and HPV-ve participants. The effect of smoking before the start of sexual activity compared to afterwards was higher among HPV+ve individuals. This pattern of association was less profound among HPV-ve participants. Temporal interactions may exists between oral HPV infection and life course smoking trajectories in relation to HNC risk.

Abstract
This study aims to evaluate the effectiveness of an educational intervention that was designed to increase human papillomavirus (HPV) awareness and knowledge among oral health providers (OHPs). HPV educational lectures and a dental information toolkit on HPV were offered to OHPs in New England in 2016-2017. OHPs included dentists and dental hygienists. Post intervention surveys were distributed 1 month later. A total of 230 participants attended the educational lectures and received the toolkit. Descriptive statistics were used to compare the difference in knowledge and preparedness about HPV before and after the intervention. Eighty-nine OHPs completed the surveys. The response rate was 38.7%; however, for each question, the number of responses varied. Fifty-four (54%) (n = 26) of survey respondents were between 55 and 75 years of age with 73.5% (n = 36) being female and 55% (n = 45) working in private practice. Post intervention, 67.5% (n = 27) of the respondents felt more prepared, 82.6% (n = 38) reported clarity of their roles in educating their patients about HPV, and 91.6% (n = 44) reported an increase in knowledge about HPV. The HPV educational intervention was well received and successful at improving self-reported knowledge, comfort level, and preparedness of OHPs in discussing HPV with their patients. OHPs have the great opportunity to educate their patients about HPV and HPV vaccination. Further continuing education efforts may improve OHPs' participation in HPV prevention.

Abstract
Background Knowledge of the prevalence of and risk factors for oral human papillomavirus (HPV) infection, especially cutaneous types, is limited. Methods A population-based study using next-generation sequencing consecutively recruited asymptomatic individuals aged 18–64 years from a proportional sampling of the general population of Hong Kong, according to age groups, gender, and regions of residence. We examined associations of alpha-, beta-, and gamma-HPVs from oral rinse samples with participants’ sociodemographics by logistic regression models. Results The prevalence of oral HPV infection among 1426 ethnic Chinese was 15.5% (95% confidence interval [CI], 13.7%–17.5%), 2.5% (95% CI, 1.8%–3.5%), 11.9% (95% CI, 10.3%–13.6%), and 2.9% (95% CI, 2.1%–3.9%) for any type, alpha-, beta-, and gamma-HPV, respectively. Prevalence of any high-risk HPV was 0.8% (95% CI, 0.4%–1.4%), and that of HPV-16 was 0.4% (95% CI, 0.2%–0.8%). HPV-8 and HPV-98 were the most common beta types detected, while HPV-4 and HPV-SD2R were the most common gamma types. Prevalence of alpha- and beta/gamma-HPV infection showed a similar pattern of increase with age, and was higher in men than women. Smoking, drinking, oral sex, and more sexual partners were associated with alpha-HPV. Teeth brushing before sleep was protective for beta/gamma-HPVs. Discussion The epidemiologic factors associated with oral infection with alpha-HPVs are different from those of beta/gamma-HPVs, suggesting different modes of acquisition and persistence.

Abstract
Objective The human papillomavirus (HPV) can cause premalignant and malignant tumors in the anogenital and oropharyngeal regions. The aim of this study was to describe the association in the prevalence of cervical, anal, and oral HPV infections in high-risk patients with biopsy-confirmed high-grade cervical lesion compared to low-risk women. Study Design A total of 718 immunocompetent women were enrolled in the study. The high-risk (HR) group consisted of 473 patients with biopsy-confirmed high-grade cervical lesion while the low-risk (LR) group consisted of other 245 women. All participants completed an anonymous self-administered questionnaire and were subjected to cervical, anal, and oral HPV genotyping using the Linear array HPV test. Results A total of 81.4% women were infected in the cervix, 43.3% in the anus, and 2.7% in the oral cavity in the HR group in comparison with only 26.9%, 24.5%, and 1.4% in the low-risk LR group, respectively. The cervical and anal HPV infections were much more frequent in the HR patients (p < 0.001); the difference in the oral HPV prevalence was not significant (p = 0.511) between groups. Concurrent cervical-anal infection was observed in 39.3% of HR women and in 8.3% of the LR patients (p < 0.001) and it significantly increased with the grade of cervical lesion (ptrend<0.001). The higher prevalence of concurrent cervical-oral, anal-oral, and cervical-anal-oral infections in HR women was statistically not significant according to the generally small oral HPV prevalence. Conclusions All HPV infections occurred more often in HR than in LR women but not all results were statistically significant. The genotype HPV 16 was found in approximately half of all infections at all sites.

Abstract
BACKGROUND Sexually transmitted infections can be spread through oral and anal heterosexual sex. There are few data on these practices in Sub-Saharan Africa. We analyzed the prevalence of heterosexual oral and anal sex among HIV Voluntary Counseling and Testing (VCT) attendees in Kinshasa and the associated sociodemographics, perceptions and behavioral factors. METHODS OKAPI (Observational Kinshasa AIDS Prevention Initiative) prospective cohort study. It evaluates the VCT impact on HIV-related knowledge and behaviors at 6 and 12-month follow-up. Since April 2016 until April 2018, 797 persons aged 15-59 years were HIV tested and replied to a baseline interview, including information about anal and oral sex. Descriptive, bi- and multivariate analyses were performed using baseline data. RESULTS Among 718 sexually active participants reporting heterosexual sex, 59% had had oral sex, 22% anal sex and 18% both practices. Among participants reporting "not" having had sex, 6% reported oral sex, 3% anal sex and 1% both. Oral sex was associated with a daily use of the Internet/mobile phone, perceiving low community HIV risk, reporting HIV-related behaviors (multiple partners, inconsistent condom use, anal, paid and forced sex) and having been pregnant. Being married-monogamous was inversely associated with oral sex. Anal sex was directly associated with having other risk sexual behaviors. CONCLUSIONS Oral and anal sex were common among people reporting heterosexual sex in Kinshasa. Perceiving a low community HIV risk and having other sexual risk behaviors are associated with these practices, which are commonly not considered as risky despite their strong association with HIV/STIs. They need to be considered when designing preventive strategies in Kinshasa.

Human papillomavirus DNA detected in fingertip, oral and bathroom samples from unvaccinated adolescent girls in Tanzania. Sex Transm Infect 2019; 95:374-379. [PMID: 30636707 PMCID: PMC6678034 DOI: 10.1136/sextrans-2018-053756] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Revised: 11/16/2018] [Accepted: 12/16/2018] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVE Human papillomavirus (HPV) DNA has been detected in vaginal samples from adolescent girls who report no previous sex and, in high-income settings, from fingertips, raising the possibility of non-sexual transmission. No such studies originate from East Africa which bears among the highest cervical cancer incidence and HPV prevalence worldwide. HPV-related oral cancer incidence is increasing, but oral HPV prevalence data from East Africa are limited. We aimed to describe the HPV DNA prevalence in genital and non-genital sites and in the bathroom of unvaccinated adolescent girls, and examine genotype concordance between sites. METHODS We nested a cross-sectional study of HPV in genital and extragenital sites within a cohort study of vaginal HPV acquisition. Unvaccinated girls age 16-18 years in Tanzania, who reported ever having had sex, were consented, enrolled and tested for the presence of HPV DNA in vaginal samples collected using self-administered swabs, oral samples collected using an oral rinse, and on fingertips and bathroom surfaces collected using a cytobrush. RESULTS Overall, 65 girls were enrolled and 23 (35%, 95% CI 23% to 47%) had detectable vaginal HPV. Adequate (β-globin positive) samples were collected from 36 girls' fingertips and HPV was detected in 7 (19%, 95% CI 6% to 33%). 63 girls provided adequate oral samples, 4 (6%, 95% CI 0% to 13%) of which had HPV DNA detected. In bathroom samples from 58 girls, 4 (7%, 95% CI 0% to 14%) had detectable HPV DNA. Of the 11 girls with extragenital HPV, six had the same genotype in >1 site. CONCLUSION We found a high prevalence of HPV in non-genital sites in adolescent girls and in their bathrooms, in this region with a high cervical cancer incidence. Concordance of genotypes between sites supports the possibility of autoinoculation.

Abstract
OBJECTIVES This study was conducted to determine the prevalence of and associated risk factors for infection with oral high-risk human papillomavirus (HR-HPV) in adult participants within England, and to explore any association with oral mucosal buccal epithelial cell and whole blood folate concentration. DESIGN This was an observational study to determine oral HR-HPV prevalence in the study population. A case-control study was performed to explore the association between infection and folate status. SETTING This study was conducted in Sheffield, UK, between April 2013 and August 2014. PARTICIPANTS Seven hundred participants, aged 18-60 years, were recruited from university students (n=179), university and hospital staff (n=163), dental hospital patients (n=13), Sexual Health Sheffield patients (n=122) and the general public (n=223). INTERVENTIONS Participants completed a lifestyle and sexual behaviour questionnaire, provided an oral rinse and gargle sample for the detection of oral HR-HPV and an oral mucosal buccal epithelial cell sample for the measurement of oral mucosal buccal epithelial cell folate. A blood sample was collected for measurement of whole blood folate concentration. OUTCOME MEASURES The prevalence of oral HR-HPV infection in the study population was the primary outcome measure. Secondary outcome measures included associations between risk factors, folate status and infection. RESULTS The prevalence of oral HR-HPV infection in this cohort was 2.2% (15/680) with 0.7% (5/680) positive for HPV16 or HPV18. Twenty samples were excluded due to insufficient material for HPV detection. Participants with oral HR-HPV infection were more likely to be a former smoker, and have a greater number of sexual and oral sexual partners. Folate status was not linked to likelihood of HPV infection. CONCLUSIONS The prevalence of oral infection with HR-HPV in adult men and women in Sheffield in the North of England was low. Smoking and sexual behaviour were associated with HR-HPV positivity. TRIAL REGISTRATION NUMBER ID14106.

Abstract
Human papillomavirus (HPV) is a potentially oncogenic sexually transmitted infection. As the incidence of oropharyngeal cancer (OPC) caused by oral HPV infections is rising, further investigation into the natural history of such infections is needed. This systematic review and meta-analysis aimed to synthesize data on the prevalence, incidence, clearance, and persistence of oral HPV infections in healthy individuals. A systematic review of literature published between January 1995 and August 2017 was conducted using Ovid MEDLINE, PubMed, Embase, and the Cochrane Library. Meta-analysis of prevalence and incidence data was conducted. Clearance and persistence data were extracted. Sixty-six studies met the inclusion criteria. Meta-analysis demonstrated an overall prevalence of 7.7% for all types of HPV and 1.4% for high-risk HPV16. The overall incidence was 4.38 cases per 1000 person-months for all HPV types and 0.92 cases per 1000 person-months for HPV16. This systematic review and meta-analysis demonstrated that oral HPV infection has a lower prevalence and incidence than cervicogenital HPV infection in healthy individuals. Nonetheless, oral HPV is still an important concern, given its oncogenicity and the rising incidence of oropharyngeal cancer. Consistency of methodology will allow for better future comparisons, particularly of infection clearance and persistence.

Abstract
Objectives: The objective of this study is to examine the human papillomavirus type 16 (HPV16) DNA copy number in the oral cavity of cancer patients using oral rinse samples. Methods: We analyzed the HPV16 DNA copy number of oral rinse samples in 13 primary oral cavity cancer patients (mean age 67.8 years, range 48–84 years) who visited the Department of Oral and Maxillofacial Reconstructive Surgery of Hiroshima University Hospital (Hiroshima, Japan). The 13 oral cavity cancers included 6 carcinomas in situ and 7 squamous cell carcinomas. Real-time PCR analysis was performed to examine the number of HPV16 E6 viral copies in oral rinse samples. Additionally, the HPV16 integration status was investigated using the real-time PCR findings for HPV16 E2 genes in HPV16 E6-positive oral rinse samples. Results: HPV16 E6 copy numbers above the detection limit in a standard curve for HPV16 E6 DNA were assessed as HPV16 positive in oral rinse samples from 6 of 13 patients. The average number of HPV16 E6 viral copies was 1.71 ± 1.72 per cell (range, 0.39–4.96 copies/cell) in six oral rinse samples. The HPV16 E2 viral load was detected in four of the six HPV16-positive oral rinse samples. Two of the six HPV16-positive oral rinse samples showed HPV16 E2 copy numbers below the detection limit, indicating the full integration of HPV16 DNA. Conclusions: The number of patients in this study was small; therefore, further investigation using a larger number of participants is required to clarify the level of HPV16 viral copy number in the oral cavity of cancer patients.

Abstract
BACKGROUND The prevalence of high-risk human papillomavirus (HPV) DNA in cases of oral cavity squamous cell carcinoma (SCC) varies widely. The aim of this study is to investigate the frequency of high-risk HPV DNA in a large Brazilian cohort of patients with oral cavity SCC. METHODS Biopsy and resected frozen and formalin-fixed paraffin-embedded specimens of oral cavity SCC were available from 101 patients who were recruited at two Brazilian centres. Stringent measures with respect to case selection and prevention of sample contamination were adopted to ensure reliability of the data. Nested PCR using MY09/MY11 and GP5+/GP6+ as well as PGMY09/11 L1 consensus primers were performed to investigate the presence of HPV DNA in the tumours. HPV-positive cases were subjected to direct sequencing. Shapiro-Wilk and Student t test were used to evaluate data normality and to compare the means, respectively. Qualitative variables were analysed by logistic regression. RESULTS Our results demonstrate that the frequency of high-risk HPV types in oral cavity SCC is very low and is less than 4%. All HPV-positive cases were HPV16. In addition, our results do not show a significant association between the tumour clinical features and the risk factors (tobacco, alcohol and HPV) for oral cavity SCC. CONCLUSION In the current study, we observed an overlapping pattern of risk factors that are related to tumour development. This, along with a low frequency of high-risk HPV DNA, supports the findings that HPV is not involved in the genesis of oral cavity SCC in Brazilian population.

Abstract
AIM The risk of malignancies in autoimmune diseases is high and is regarded to be due to immunological abnormalities, the use of immunosuppressive agents, and/or chronic inflammation. The aim of this study was to investigate the incidence and risk of malignancies in patients with autoimmune hepatitis (AIH) type 1 in Japan. METHODS Two hundred and fifty-six patients diagnosed with AIH were enrolled. A person-year calculation was carried out for AIH patients, and the numbers of expected events were clarified using data from "The Monitoring of Cancer Incidence in Japan Project" in order to examine the standard incident rate (SIR) of each type of malignancy. Biochemical data regarding carcinogenesis and its background factors were also examined. RESULTS Twenty-seven patients (10.5%) developed malignancies; 11 (4.3%) with hepatobiliary cancer and 16 (6.3%) with extrahepatic malignancies. The overall SIR for malignancies in AIH was significantly high at 2.04 (95% confidence interval [CI], 1.34-2.96), and was high among female patients at 2.49 (95% CI, 1.60-3.71). The SIR for hepatobiliary cancer was 14.14 (95% CI, 7.05-25.30), and was markedly high for female patients at 21.83 (95% CI, 10.45-40.16). The SIR for oral/pharyngeal cancer was significantly high for female patients at 14.61 (95% CI, 1.64-52.77). The risk factors for hepatobiliary cancer at the diagnosis of AIH were low levels of alanine aminotransferase (P = 0.0226), low platelet counts (P < 0.0001), and cirrhosis (P = 0.0004). The risk factor for extrahepatic malignancy was relapse of AIH (P = 0.0485). CONCLUSION The risk of malignancies was generally high among AIH patients. Those with the risk factors of malignancies should be carefully followed up.

Prevalence and genotypes of human papillomavirus in saliva and tumor samples of head and neck cancer patients in Hungary. INFECTION GENETICS AND EVOLUTION 2018; 59:99-106. [PMID: 29408738 DOI: 10.1016/j.meegid.2018.01.030] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Revised: 01/29/2018] [Accepted: 01/30/2018] [Indexed: 01/08/2023]
Abstract
In addition to traditional risk factors such as smoking, alcohol consumption and betel nut use, human papillomavirus (HPV) infection also plays a role in the development of head and neck squamous cell carcinomas (HNSCCs). Although among European countries the highest incidence and mortality rates of head and neck cancer types were recorded in Hungary, data regarding HPV prevalence in HNSCCs is scarce. We collected biopsy and saliva samples from patients diagnosed with HNSCC or oral potentially malignant disorders (OPMDs) and tested them for the presence of HPV using the PCR consensus primer set MY09/11 and the GP5+/6+ primer pair. HPV genotypes were assessed by sequencing of the amplified PCR fragments. Oral mucosa and saliva samples from tumor- and OPMD-free individuals were also analysed. HPV was detected in 11 out of 60 HNSCC samples (18%). All of the HPV positive tumors carried HPV type 16. 5 out of the 57 saliva samples collected from HNSCC patients was HPV positive (8.8%); among them, in addition to HPV16, HPV13 was also detected. Tumors located to the oropharynx had the highest HPV positivity rate with 50% (7 out of 14), which was significantly higher than the HPV prevalence in oral mucosa samples collected from controls (0 out of 20; p > 0.001) or in OPMD biopsies (0 out of 21, p > 0.001). 2 out of 57 control saliva samples (3.5%, subtype HPV13 and 11) and 3 out of 39 saliva samples from OPMD patients (7.7%, subtype HPV18, 81 and 10) were HPV positive. Our data suggested that HPV16 infection may contribute, in concert with cigarette smoking, to the development of a subset of head and neck cancers in Hungary. HPV16 infection per se does not account, however, for the high HNSCC incidence rate recorded in this country.

Abstract
Mouse papillomavirus has shown broad tissue tropism in nude mice. Previous studies have tested cutaneous infections in different immunocompromised and immunocompetent mouse strains. In the current study, we examined mucosal infection in several immunocompetent and immunocompromised mouse strains. Viral DNA was monitored periodically by Q-PCR of lavage samples. Immunohistochemistry and in situ hybridization were used to determine viral capsid protein and viral DNA respectively. All athymic nude mouse strains showed active infections at both cutaneous and mucosal sites. Interestingly, NOD/SCID mice, which have a deficiency in T, B, and NK cells, showed minimal disease at cutaneous sites but developed persistent infection at the mucosal sites including those of the anogenital region and the oral cavity. Three strains of immunocompetent mice supported mucosal infections. Infections of the lower genital tract in heterozygous (immunocompetent) mice of the NU/J strain progressed to high grade dysplasia and to carcinoma in situ. Anti-MmuPV1 neutralizing antibodies were detected in the sera of all immunocompetent animals. Our findings demonstrate that the mucosae may be the preferred sites for this virus in mice. The mouse model is expected to be a valuable model for the study of mucosal papillomavirus disease, progression, and host immune control.

High HPV16 E6 viral load in the oral cavity is associated with an increased number of bacteria: A preliminary study. Biomed Rep 2017; 8:59-64.

Abstract
In a previous study, the present research group reported that males had a significantly higher prevalence of human papillomavirus (HPV)16 than females in oral rinse samples. The objective of the present study was to examine the relationship between HPV16 viral load and clinical factors, including remaining teeth, denture use and numbers of oral bacteria. A total of 124 patients (48 males and 76 females; mean age, 61.6 years; age range, 20-97 years) who visited the Department of Oral and Maxillofacial Reconstructive Surgery of Hiroshima University Hospital (Hiroshima, Japan) between November 2016 and August 2017 were analyzed. None of the patients had evidence of oral cancer or pre-malignant lesions, including epithelial dysplasia and leukoplakia. Quantitative polymerase chain reaction (qPCR) analysis was employed to examine the number of HPV16 viral copies. Furthermore, the number of oral bacteria was determined using the dielectrophoretic impedance measurement method. HPV16 was below the limit of detection in qPCR findings for samples obtained from 30 of the 124 subjects, thus the association of HPV16 viral copy number with clinical parameters was examined in the remaining 94 patients. The average number of HPV16 E6 DNA copies was 1.65±3.47 copies/cell (range, 0.07-25.3 copies/cell) and was significantly higher in subjects with a high oral bacteria count [≥106.5 colony forming unit (CFU)/ml] than in those with a low count (<106.5 CFU/ml) (0.79±0.98 vs. 2.06±4.11 copies/cell; P=0.030). The present results indicated that HPV16 viral load may be related to an increased bacterial number in the oral cavity. Further investigations are required to clarify the correlation between oral HPV load and oral hygiene status.
