Oral-genital human papillomavirus infection in Polish couples: frequent detection of HPV 42.

ABSTRACT: BACKGROUND:Human papillomavirus (HPV) contributes to the development of cervical and oropharyngeal tumors. The increased incidence of HPV associated oropharyngeal tumors is lately being observed also in Polish population. The worldwide distribution of HPV varies and the studies rarely combine analysis of virus genotypes in both: genital and oropharyngeal locations. Therefore, in our study, we investigated HPV distribution in both anatomical sites of females with previous history of cervical cancer or with pre-cancerous lesion and their partners to establish the dominant types in Polish couples in genital and oropharyngeal areas, as they can be easily sexually transmitted. METHODS:The study group consisted of 197 females and their partners. Each female had current or previous cervical pathology and HPV detected in gynecological swab with the use of Anyplex™ II HPV28 Detection system. This system is based on multiplexed real time PCR and enables detection of 19 high-risk and 9 low-risk HPVs. RESULTS:Beside women, the virus was found in 114/197 of men in their foreskin swabs. Additionally, HPV was detected in oropharyngeal swabs of 39/197 female and 56/197 male participants. HPV 16/31/42/39/54 dominated in female and HPV 66/42/16/31/53 in male genital locations. The incidence of HPV in oropharynx was lower, top five genotypes included: HPV 6/39/42/35/16 in women compared to HPV 39/6/42/40/33 in men. HPV16 was the most frequently detected virus type, found in 70/197 examined cervical swabs. It was significantly more prevalent as single infection in females, previously treated for the cervical cancer (p =?0.035). Moreover, regular presence of low risk type 42 was noticeable in both sexes, in both kind of swabs. There was a trend observed towards its prevalence as single infectious agent in women with previous history of cervical cancer (p =?0.069). CONCLUSIONS:Our results showed the distribution of HPV genotypes in Polish couples, in which each woman is HPV positive, indicating a common infection of HPV 42, regardless of sex and anatomical site. These findings shed new light on HPV 42 significance, however they should be verified on a larger group of Polish participants, followed regularly in 6?months intervals, in oral as well as in genital areas.

Project description:Background:The burden of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is disproportionately high among men, yet empirical evidence regarding the difference in prevalence of oral HPV infection between men and women is limited. Concordance of oral and genital HPV infection among men is unknown. Objective:To determine the prevalence of oral HPV infection, as well as the concordance of oral and genital HPV infection, among U.S. men and women. Design:Nationally representative survey. Setting:Civilian noninstitutionalized population. Participants:Adults aged 18 to 69 years from NHANES (National Health and Nutrition Examination Survey), 2011 to 2014. Measurements:Oral rinse, penile swab, and vaginal swab specimens were evaluated by polymerase chain reaction followed by type-specific hybridization. Results:The overall prevalence of oral HPV infection was 11.5% (95% CI, 9.8% to 13.1%) in men and 3.2% (CI, 2.7% to 3.8%) in women (equating to 11 million men and 3.2 million women nationwide). High-risk oral HPV infection was more prevalent among men (7.3% [CI, 6.0% to 8.6%]) than women (1.4% [CI, 1.0% to 1.8%]). Oral HPV 16 was 6 times more common in men (1.8% [CI, 1.3% to 2.2%]) than women (0.3% [CI, 0.1% to 0.5%]) (1.7 million men vs. 0.27 million women). Among men and women who reported having same-sex partners, the prevalence of high-risk HPV infection was 12.7% (CI, 7.0% to 18.4%) and 3.6% (CI, 1.4% to 5.9%), respectively. Among men who reported having 2 or more same-sex oral sex partners, the prevalence of high-risk HPV infection was 22.2% (CI, 9.6% to 34.8%). Oral HPV prevalence among men with concurrent genital HPV infection was 4-fold greater (19.3%) than among those without it (4.4%). Men had 5.4% (CI, 5.1% to 5.8%) greater predicted probability of high-risk oral HPV infection than women. The predicted probability of high-risk oral HPV infection was greatest among black participants, those who smoked more than 20 cigarettes daily, current marijuana users, and those who reported 16 or more lifetime vaginal or oral sex partners. Limitation:Sexual behaviors were self-reported. Conclusion:Oral HPV infection is common among U.S. men. This study's findings provide several policy implications to guide future OPSCC prevention efforts to combat this disease. Primary Funding Source:National Cancer Institute.

Project description:BackgroundHuman papillomavirus (HPV) causes cancers in men, including penile, anal, and oropharyngeal cancers. This cross-sectional study aimed to investigate the prevalence, the genotypes, and the risk factors of HPV infections in the oral cavity, compared to those in the genitals, among males diagnosed with sexually transmitted infections (STIs) in Vietnam.MethodsOral, urinary, penile, and urethral samples were collected from 198 male Vietnamese patients with STIs (median age 31.0 years, range 17-68). HPV DNA was isolated and amplified with PCR, with modified and/or original GP5+/GP6+ primers. Samples were genotyped with a gene array assay and/or population sequencing.ResultsHPV DNA was detected in 69 (34.8%) of 198 patients. Of these, 16 patients (8.1%) had infections in the oral cavity and 58 (29.3%) had infections in the genitals (4.5% in the urine, 25.8% in the penis, and 8.1% in the urethra). The concordance of HPV infections between the oral cavity and the genitals was poor (kappa = 0.01). Of the 16 patients with oral HPV DNA, 11 (68.8%) had no HPV DNA in the genitals. In the remaining five patients, HPV DNA was found at both sites, but only one showed similar strains at both sites. In the other four patients, the HPV genotypes were completely discordant between these sites. HPV18 was the most common high-risk HPV genotype in both oral (9/16, 56.3%) and genital (10/58, 17.2%) sites. Multivariable analyses showed that older age (OR 1.05), higher education (OR 2.17), and no knowledge of STIs (OR 4.21) were independent risk factors for genital HPV infections; in contrast, only older age (OR 1.05) was an independent risk factor for oral HPV infections.ConclusionsThe low concordance of HPV genotypes between oral and genital infection sites suggested that the acquisition, persistence, and/or clearance of HPV infections were different between these sites. Although HPV DNA was detected significantly less frequently in oral samples than in genital samples, oral samples should also be used for HPV screening in men.

Project description:The association between partner human papillomavirus (HPV) viral load and incident HPV detection in heterosexual couples is unknown.HPV genotypes were detected in 632 human immunodeficiency virus (HIV)-negative couples followed for 2 years in a male circumcision trial in Rakai, Uganda, using the Roche HPV Linear Array. This assay detects 37 genotypes and provides a semiquantitative measure of viral load based on the intensity (graded 1-4) of the genotype-specific band; a band intensity of 1 indicates a low genotype-specific HPV load, whereas an intensity of 4 indicates a high load. Using Poisson regression with generalized estimating equations, we measured the association between partner's genotype-specific viral load and detection of that genotype in the HPV-discordant partner 1 year later.Incident detection of HPV genotypes was 10.6% among men (54 of 508 genotype-specific visit intervals) and 9.0% among women (55 of 611 genotype-specific visit intervals). Use of male partners with a baseline genotype-specific band intensity of 1 as a reference yielded adjusted relative risks (aRRs) of 1.14 (95% confidence interval [CI], .58-2.27]) for incident detection of that genotype among women whose male partner had a baseline band intensity of 2, 1.75 (95% CI, .97-3.17) among those whose partner had an intensity of 3, and 2.52 (95% CI, 1.40-4.54) among those whose partner had an intensity of 4. Use of female partners with a baseline genotype-specific band intensity of 1 as a reference yielded an aRR of 2.83 (95% CI, 1.50-5.33) for incident detection of that genotype among men whose female partner had a baseline band intensity of 4. These associations were similar for high-risk and low-risk genotypes. Male circumcision also was associated with significant reductions in incident HPV detection in men (aRR, 0.53 [95% CI, .30-.95]) and women (aRR, 0.42 [95% CI, .23-.76]).In heterosexual couples, the genotype-specific HPV load in one partner is associated with the risk of new detection of that genotype in the other partner. Interventions that reduce the HPV load may reduce the incidence of HPV transmission.
