SUMMARYAlcohol consumption is a possible co-factor of high-risk human papillomavirus (HR-HPV) persistence, a major step in cervical carcinogenesis, but the association between alcohol and continuous HPV infection remains unclear. This prospective study identified the association between alcohol consumption and HR-HPV persistence. Overall, 9230 women who underwent screening during 2002–2011 at the National Cancer Center, Korea were analysed in multivariate logistic regression. Current drinkers [odds ratio (OR) 2·49, 95% confidence interval (CI) 1·32–4·71] and drinkers for ⩾5 years (OR 2·33, 95% CI 1·17–4·63) had a higher risk of 2-year HR-HPV persistence (HPV positivity for 3 consecutive years) than non-drinkers and drinkers for <5 years, respectively (vs. HPV negativity for 3 consecutive years). A high drinking frequency (⩾twice/week) and a high beer intake (⩾3 glasses/occasion) had higher risks of 1-year (OR 1·80, 95% CI 1·01–3·36) HPV positivity for 2 consecutive years) and 2-year HR-HPV persistence (OR 3·62, 95% CI 1·35–9·75) than non-drinkers. Of the HPV-positive subjects enrolled, drinking habit (OR 2·68, 95% CI 1·10–6·51) and high consumption of beer or soju (⩾2 glasses/occasion; OR 2·90, 95% CI 1·06–7·98) increased the risk of 2-year consecutive or alternate HR-HPV positivity (vs. consecutive HPV negativity). These findings suggest that alcohol consumption might increase the risk of cervical HR-HPV persistence in Korean women.

Full textAbstract:
Introduction: Condyloma acuminata that is also known as genital warts are one of the most common sexually transmitted that caused by infection of Human papillomavirus (HPV). Persistent infection of Low Risk (LR) or High risk (HR) HPV is a risk factor for progress into benign or malignant cancer. The objective is to analyze distribution of genotype LR-HPV and HR-HPV at condyloma acuminata in anogenital region. Methods: A cross sectional study using were 36 lesions from men and women of condyloma acuminata patients. All subject signed the informed consent and ethic obtained from our institution, number 382/Panke.KKE/V/2016. The specimen was used to histopathological examination and to identified 40 genotypes of HPV using a reverse line blot assay.Results: The All patients were diagnosed as condyloma acuminata, some with focus dysplasia and koilocytosis. All patients were positive for HPV, including LR-HPV were HPV 6, 11, 42, 54, 61, 81,87,89 and HR-HPV were HPV 18, 26, 45, 51, 52, 66, 67, 68B, 69, 82. The single infection of LR-HPV was 44.4%, multiple infection LR/LR-HPV was 13,9% and the multiple infection of LR/HR-HPV was 41.7%. The LR-HPV infected 70,6% and HR-HPV infected 29,4%. Conclusion: LR-HPV is the major infection of condyloma acuminata, in single infection or multiple infection with HR-HPV. The most common infections were HPV 11, followed by HPV 6, HPV 18, HPV 51, and HPV 82. The determination of genotype of HPV can be used to predict the malignant transformation.

Full textAbstract:
Lung cancer is a very prevalent and heterogeneous group of malignancies, and most of them are etiologically associated with tobacco smoking. However, viral infections have been detected in lung carcinomas, with high-risk human papillomaviruses (HR-HPVs) being among them. The role of HR-HPVs in lung cancer has been considered to be controversial. This issue is due to the highly variable presence of this virus in lung carcinomas worldwide, and the low viral load frequently that is detected. In this review, we address the epidemiological and mechanistic findings regarding the role of HR-HPVs in lung cancer. Some mechanisms of HR-HPV-mediated lung carcinogenesis have been proposed, including (i) HPV works as an independent carcinogen in non-smoker subjects; (ii) HPV cooperates with carcinogenic compounds present in tobacco smoke; (iii) HPV promotes initial alterations being after cleared by the immune system through a “hit and run” mechanism. Additional research is warranted to clarify the role of HPV in lung cancer.

Full textAbstract:
Context.—We reported previously that more than one-third (37%) of primary bladder squamous cell carcinomas (SCCs) demonstrate diffuse p16 immunoreactivity independent of gender. This observation made us question whether p16 overexpression in bladder carcinoma is due to human papillomavirus (HPV)–dependent mechanisms. Objectives.—To determine whether the presence of high-risk HPV (HR-HPV) DNA could be detected in these tumor cells. Design.—Fourteen cases of primary bladder SCC, which were positive for p16 by immunohistochemistry, were probed for the detection of HR-HPV by in situ hybridization and the signal amplification Invader assay. Samples positive for detection of HR-HPV by Invader assay were amplified by using HR-HPV type-specific primers, and amplification products were DNA sequenced. Results.—Detection of HR-HPV by the in situ hybridization method was negative in all cases (0 of 14). However, in 3 of 14 cases (21.4%), the presence of HR-HPV DNA was detected with the Cervista HPV HR Invader assay, which was followed by identification of genotype. All positive cases were confirmed by using HR-HPV type-specific amplification followed by DNA sequencing. Identified HR-HPV genotypes included HPV 16 (2 cases) and HPV 35 (1 case). Conclusions.—High-risk HPV DNA is detectable in a subset of primary bladder SCCs. Based on the well-documented carcinogenic potential of HR-HPV, there is a necessity for additional studies to investigate the role of HR-HPV in bladder carcinogenesis.

Full textAbstract:
Cervical, anogenital, and some head and neck cancers (HNC) are etiologically associated with high-risk human papillomavirus (HR-HPV) infection, even though additional cofactors are necessary. Epidemiological studies have established that tobacco smoke (TS) is a cofactor for cervical carcinogenesis because women who smoke are more susceptible to cervical cancer when compared to non-smokers. Even though such a relationship has not been established in HPV-related HNC, a group of HPV positive patients with this malignancy are smokers. TS is a complex mixture of more than 4500 chemical compounds and approximately 60 of them show oncogenic properties such as benzo[α]pyrene (BaP) and nitrosamines, among others. Some of these compounds have been evaluated for carcinogenesis through experimental settings in collaboration with HR-HPV. Here, we conducted a comprehensive review of the suggested molecular mechanisms involved in cooperation with both HR-HPV and TS for epithelial carcinogenesis. Furthermore, we propose interaction models in which TS collaborates with HR-HPV to promote epithelial cancer initiation, promotion, and progression. More studies are warranted to clarify interactions between oncogenic viruses and chemical or physical environmental factors for epithelial carcinogenesis.

ObjectiveTo evaluate the association between potential risk factors for high-risk human papillomavirus (HR-HPV) infection and cofactors for cervical intraepithelial lesions grade 2 or worse (CIN2+) in women attending cervical screening in Amazonian Peru.Materials and MethodsParticipants completed a risk factor questionnaire before screening. High-risk human papillomavirus infection was determined by Hybrid Capture II. Logistic regression was used to evaluate associations between potential risk factors for HR-HPV infection and between cofactors and risk of CIN2+ among women with HR-HPV infection.ResultsScreening and questionnaires were completed by 5435 women aged 25 to 49 years. The prevalence of HR-HPV was 12.6% (95% confidence interval [CI], 11.8%–13.6%) and decreased by age. Early age at first sexual intercourse and several lifetime sexual partners increased the risk of having HR-HPV (age-adjusted odds ratio [AOR] of age at first sexual intercourse <18 vs ≥20, 1.5; 95% CI, 1.2–2.0; AOR of ≥5 lifetime sexual partners vs 1, 2.1; 95% CI, 1.4–3.2). Among women with HR-HPV infection, those with no schooling (AOR relative to 1–5 years of schooling, 3.2; 95% CI, 1.3–8.3) and those with parity ≥3 (AOR relative to parity <3, 2.6; 95% CI, 1.4–4.9) were at increased risk of CIN2+. The effect of parity was stronger for cancer (AOR of parity ≥3 vs <3, 8.3; 95% CI, 1.0–65.6). Further analysis showed that the association between parity and CIN2+ was restricted to women younger than 40. Most women (83%) had previously been screened. Sixty-four percent of CIN2+ cases detected in this study occurred in women who reported having had a Papanicolaou test in the previous 3 years. Only 4 of 20 cancers were detected in women never screened before. Having had a previous abnormal Papanicolaou test increased the risk of CIN2+ (OR, 16.1; 95% CI, 6.2–41.9).ConclusionAmong women with HR-HPV, high parity (in young women), no schooling, lack of good-quality screening and of adequate follow-up care are the main risk factors for high-grade cervical disease in Peru.

Full textAbstract:
Background. High-risk human papillomavirus (hr-HPV) infection is a necessary cause of cervical cancer. However, other common lower genital tract microbes may increase hr-HPV infection and their related cervical cytopathy. Methods. To confirm this hypothesis, cervical brush and vaginal swab specimens were collected from 826 adult patients who were divided into the hr-HPV-positive group (254) and the negative group (572) by real-time PCR assay. Cervical specimens were tested for Ureaplasma parvum (UP), Ureaplasma urealyticum (UU), and Chlamydia trachomatis (CT) using PCR analysis. Vaginal secretion was detected for Trichomonas vaginalis (TV), Candida spp., and bacterial vaginosis (BV) with conventional assay. Results. Among hr-HPV-positive women, UP was found in 51.6%, UU in 15.4%, CT in 15.7%, Candida spp. in 11.0%, TV in 3.1%, and BV in 20.5%. In the hr-HPV-negative group, UP was positive in 36.2%, UU in 8.6%, CT in 4.0%, Candida spp. in 12.4%, TV in 0.2%, and BV in 7.0%. Multivariate logistic regression analysis with age-adjusted showed that UU (OR, 1.757), UP (OR, 1.804), CT (OR, 3.538), BV (OR, 3.020), and TV (OR, 14.109) were risk factors on hr-HPV infection (P<0.05). Conclusion. These microbes might induce cervical chronic inflammation that would damage the mucosal barrier and immune protection to promote the infection of hr-HPV.

Full textAbstract:
Human papillomavirus (HPV) infection is a significant etiological factor and an important prognosticator in cervical cancer. Indeed, researchers worldwide have confirmed these roles for high-risk HVPs in over 70% of cervical cancer cases. According to the World Health Organization, approximately 561,200 new cancer cases (5.2% of all new cancers) are attributed to HPV infection. Over 120 types of HPV are classified further as either low-risk HPV (LR-HPV) or high-risk HPV (HR-HPV) based on their oncological potential of transforming cells. The LR-HPV types cause benign hyperproliferative lesions (i.e. genital warts) while the HR-HPV types are strongly associated with premalignant and malignant cervical lesions. Data on the prevalence of HPV, survival of infected patients, and mortality rate are scarce in Saudi Arabia. The unsubstantiated assumption of a low prevalence of HPV in Saudi Arabia has contributed to limiting HPV research in this conservative country. Therefore, the goal of this review is to shed light on the current HPV research being conducted and the prevalence of HPV in Saudi Arabia.

Full textAbstract:
Persistent infection with high-risk human papillomaviruses (HR-HPVs), particularly HPV16 and 18, has long been known to induce cervical cancer progression. However, given that a minority of HPV-infected women develop cancer, analysis of HR-HPV-infected women could help to predict who is at risk of acquiring cervical cancer. Therefore, to improve HR-HPVs detection, we used the FDA-approved cobas® 4800 HPV and REBA HPV-ID® HPV assays to detect HR-HPVs in colposcopy-derived cervical cells from 303 patients, detecting 72.28% (219) and 71.62% (217) of HR-HPVs positive cases, with HPV16 detection rates of 35.64% (108) and 30.69% (93), respectively. Of the HPV16-positive cases, cobas® 4800 and REBA HPV-ID® identified 28.81% (51) and 25.42% (45) of the CIN1 cases, and 55% (33) and 50% (30) of the 60 CIN2/3 cases, respectively. HPV-diagnostic concordance was 82.17% overall (kappa = 0.488), 87.45% for HR-HPVs (kappa = 0.689), and 88.33% for CIN2/3 (kappa = 0.51). The HR-HPVs detection rates of these assays were comparable. Our findings reveal that the FDA-approved HR-HPVs detection assay is appropriate for screening women with HR-HPVs infection, and for predicting increased risk of cervical cancer progression. REBA HPV-ID® can be used to detect low risk-HPV types in high-grade cervical lesions that are HR-HPV negative as well as in the distribution of HPV types.

Objective. To determine the prevalence and risk factors for oral high-risk human papillomavirus (HR-HPV) infection in human immunodeficiency virus (HIV)-infected men. Materials and methods. Consecutive male outpatients with HIV-infection were enrolled. Demographic and behavioral risk data were obtained. Anal swabs and oral rinses were tested for HR-HPV DNA. Oral, pharyngeal and video laryngoscopy examinations were performed for detection of lesions. Results. The prevalence of HR-HPV oral infection was 9.3% (subtypes other than HR HPV 16/18 predominated). The prevalence of anal HR-HPV infection was 75.7%. The risk factors for oral infection with HR-HPV were tonsillectomy (OR=13.12) and years from HIV diagnosis (OR=1.17). Conclusions. Tonsillectomy and years from HIV diagnosis were associated with oral HPV infection. No association was found between oral and anal HR-HPV infections. This is the first study reporting the prevalence and risk factors for oral HR-HPV infection in Mexican HIV-infected population.

Introduction: The purpose of this study was to detect the expression of local cytokines in cervical mucosa between patients with transient and persistent HR-HPV infection with or without CIN.
Methodology: A total of 150 patients who were diagnosed as HR-HPV infection in Tianjin Central Hospital of Obstetrics and Gynecology from January 2016 to December 2016 were included in this study. The expression levels of 9 cytokines in 150 patients with HR-HPV infection, including interleukin (IL)-1β, IL-4, IL-6, IL-8, IL-10, IL-12, IL-12p70, IL-21, interferon (IFN)-γ and tumor necrosis factor (TNF)-α, were simultaneously measured by using a multiplex immunoassay. Moreover, HR-HPV genotype was performed by using pyrosequencing. The association between cytokines and HPV genotype was also investigated.
Results: There was a statistically significant difference in IL-1β level between patients with HPV transient infection and HPV persistent infection (p = 0.041). There were statistically significant differences in the levels of IL-1β, IL-10, IL-21 and TNF-α between patients with low grade squamous intraepithelial lesion (LSIL) and high grade squamous intraepithelial lesion (HSIL) (p = 0.011, p = 0.008, p = 0.046 and p = 0.019, respectively).
Conclusions: Pro-inflammatory cytokines, IL-1β and TNF-α, and Th2 type cytokines, IL-10 and IL-21, became stronger in cervical mucosa with the progression of CIN. IL-1β may be advantageous for HR-HPV persistent infection.

Full textAbstract:
Background: persistent infection with high-risk human papillomavirus (HR-HPV) is the primary cause for the development of various anogenital cancers in females and males. Most infections are either latent or subclinical and the majority occur as asymptomatic. HPV infections are not currently treatable by antiviral compounds. Micro-immunotherapy (MI) medications using high dilutions of cytokines and specific nucleotide sequences have been developed to treat targeted viral infections and are currently prescribed in medical practice as immune regulators: 2L®PAPI (Labo’Life) is indicated for HPV infection and may represent a new therapeutic approach.
Aims: this exploratory study was to assess the effectiveness of 2L®PAPI on HPV infection eradication in HR-HPV infected asymptomatic patients attending an STD Centre in a long-term microbiological follow-up population survey.
Methodology: adult patients of both genders, diagnosed with HR-HPV infection, with no evidence of symptomatic HPV or anogenital cancer, were followed during a 2 year-period (2009-2010). Selected patients had not previously been vaccinated for HPV or treated with medications having an impact on the immune system. HPV testing was performed on biological samples using PCR detection (Innogenetics, Italy). In addition, detection of E6/E7 mRNA of five carcinogenic HPV types was performed by EasyQ HPV (BioMerieux, Italy). HPV-positives were requested by their urology specialist to take 2L®PAPI (composition in table 1) during 4 months (1 caps/day by sublingual route). Globally 46 patients were followed: 23 treated with MI medication, and 23 not treated.
Results: one third of selected patients were lost at the control visit (15/46). At the end of the study period, HR-HPV negativity was observed in 50% (8/16) of patients under MI medication in comparison with only 7% (1/15) of the non treated patients who were HPV-DNA negative at the follow-up visit (p=0.01071, Mid-P exact test). This result is in accordance with our previous results which showed long lasting persistence of HR-HPV infection in a male cohort.
Conclusions: the relevant percentage of lost patients at follow-up reflects the scarce information and awareness of this infection within asymptomatic people in Italy. 2L®PAPI was efficient in eradicating 50% of HR-HPV infections in treated patients, including 60% of HPV-16. These promising data emphasize the importance of redirecting immune responses in viral infections.

Background. Infection with and persistence of high-risk human papillomavirus (HR-HPV) are the strongest risk factors for cervical cancer. In addition, other genital microorganisms may also be involved in the progression of HPV-associated lesions. Objetive. To evaluate the association of the vaginal microbiota (Candida spp., Trichomonas vaginalis, and bacterial vaginosis) with HR-HPV infection in Spanish female sex workers (FSWs). Methods. This cross-sectional study involved 208 (FSWs; age, 18–49 years) who visited a sexually transmitted infection (STI) information and prevention center (SERGAS) between January 2010 and December 2011. Face-to-face interviews were carried out. Cervical and vaginal samples were examined for human papillomavirus (HPV), Trichomonas vaginalis, Candida spp., and microorganisms related to bacterial vaginosis (BV). Results. HR-HPV was found to be significantly associated with BV in FSWs with positive results for HPV16-related types (31, 33, 35, and 52). T. vaginalis was isolated in FSWs with the following HR-HPVs: 18, 45, 66, and 68. Candida spp. were isolated only in FSWs with HPV 18-positive infection. Conclusion. We demonstrate a significant prevalence of HR-HPVs in FSWs with disturbances in the vaginal microbiota.

Background. Mounting evidence suggests an association between human papillomavirus (HPV) and HIV acquisition. This study aimed to explore this association among South African female sex workers (FSWs).Methods. We used data from 88 HIV-negative FSWs who participated in a vaginal gel (COL-1492) trial. Cervicovaginal rinse samples, obtained before HIV-seroconversion, were genotyped into high-risk (HR-) and low-risk (LR-) HPV. HIV-adjusted hazard ratios (aHRs) and 95% confidence intervals (CI) were estimated using Cox survival analysis.Results. HR- and LR-HPV prevalences were 70.5% (95% CI : 60.5–79.2) and 60.2% (95% CI : 49.9–70.0), respectively. Twenty-five women HIV seroconverted. Controlling for background characteristics and other sexually transmitted infections, HIV aHR increased by a factor of 1.7 (95% CI : 1.01–2.7,Plinear trend= 0.045) for an increase of one unit of the number of HR-HPV genotypes.Conclusions. HIV seroconversion among FSWs is associated with genital HR-HPV infection. Further investigation is warranted, including testing the possible protective effect of available HPV vaccines on HIV acquisition.

Introduction. Cervical cancer is the most common cancer among Mexican women. The goal of the present study was to determine the prevalence and distribution of HPV types in women from Mexico City.Methods. Our study was conducted in the Clinica de Especialidades de la Mujer de la Secretaría de la Defensa Nacional, Mexico. Random samples were taken from 929 healthy women requesting a cervical Papanicolaou examination. Detection and genotyping of HPV were performed by multiplex PCR, with the HPV4A ACE Screening kit (Seegene).Results. 85 of nine hundred twenty-nine women (9.1%) were infected with HPV. Of HPV-positive women, 99% and 1% had high- and low-risk HPV genotypes, respectively. The prevalence of the 16 high-risk (HR) HPV types that were screened was 43% : 42% (18) were HPV positive and 14% (16) were HPV positive, which includes coinfection. Multiple infections with different viral genotypes were detected in 10% of the positive cases. Abnormal cervical cytological results were found in only 15.3% of HPV-positive women, while 84.7% had normal cytological results.Conclusions. We found a similar prevalence of HPV to previous studies in Mexico. The heterogeneity of the HPV genotype distribution in Mexico is evident in this study, which found a high frequency of HPV HR genotypes, the majority of which were HPV 18.

High-risk papillomavirus (HR-HPV) testing combined with cytology improves the detection of cervical lesions and increases length of screening intervals. For a population-based HR-HPV survey, testing automation is in great need. The Cobas 4800 HPV Test System is a fully automated assay that can simultaneously detect HPV16, HPV18, and other 12 pooled HR-HPV genotypes. This system has been employed for HR-HPV screening in a number of countries; however, such application in a large population in China has not been documented. In this study, we employed the Cobas 4800 HPV Test System to detect HR-HPV in cervical cytology specimens collected from a total of 5650 asymptomatic women from a region of South China. We reported the following: (1) the prevalence of the 14 genotypes of HR-HPV was 12.96%; (2) for those with HR-HPV infection, 2.25% were positive for HPV16, 0.50% for HPV18, 9.15% for pooled 12 HPV types, and 1.06% for multiple HPV infection; and (3) there was no significant difference in the HR-HPV prevalence among different age groups. HPV16 and HPV18 have been shown to be the predominant HPV types found in cervical cancer patients in some regions in China, indicating that a fully automated assay like the Cobas 4800 HPV Test System is especially valuable for population-based HR-HPV screening in these regions as this assay can concurrently detect HPV16 and HPV18.

Recently, conflicting results on human papillomavirus (HPV) clearance have been reported and the data on the accumulation of incident HPV infections are still fragmentary. Thus, we completed an analysis of the age-specific incidence and clearance rates of high-risk (HR) HPV infectionsin 448 women participating in a multi-centre screening study in three New Independent States countries. At baseline, 239 of the 448 women were negative for HR HPV DNA, whereas 209 were HR HPV-positive and cleared HR HPV during the prospective follow-up. The cumulative incidence and clearanceof HR HPV were modelled using life-table techniques. The monthly incidence rates of HR HPV were significantly age-dependent ( P = 0.0001), whereas monthly clearance rates remained constant across the nine age groups ( P = 0.920). The incidence rates (3.04% and 2.65%) exceeded theclearance rates in the two youngest age groups only, 15–20- and 21–25-year-old women, and remained lower (0–0.84%) in all other age groups. The cumulative rate of incident HR HPV infections (1.0%) was significantly lower than the overall clearance rate (1.9%) ( P =0.001). In life-table analysis, incident HR HPV infections between the nine age groups were significantly different ( P = 0.0001), while cumulative HR HPV clearance was identical in all groups ( P = 0.822). The accumulation of incident HR HPV infections is significantly age-related,whereas virus clearance remains constant between 15 and 60 years of age. These distinct age-specific incidence and clearance rates explain the differences in age-specific prevalence of HR HPV infections in the study population.

Anogenital human papillomaviruses (HPV) are highly prevalent in sexually active populations, with HR-HPV being associated with dysplasia and cancers. The consequences of cervical HPV infection are well-known, whereas those of the anus are less clear. The correlation of cervical and anal HPVs with the increasing number of anal cancers in women has not been studied yet. The objective of our prospective study was to determine whether cervical and anal HPV correlated in a cohort of women recruited in a university hospital in Switzerland. Recruitment was conducted in the gynecology clinic, the colposcopy clinic, and the HIV clinic. Cervical and anal HPV genotyping and cytology were performed. Overall, 275 patients were included (360 were initially planned), and among them, 102 (37%) had cervical HR-HPV. Patients with cervical HR-HPV compared to patients without cervical HR-HPV were significantly younger (39 vs. 44 yrs, p < 0.001), had earlier sexual intercourse (17.2 vs. 18.3 yrs, p < 0.01), had more sexual partners (2.9 vs. 2.2, p < 0.0001), more dysplastic cervical cytology findings (42% vs. 19%, p < 0.0001) and higher prevalence of anal HR-HPV (59% vs. 24%, p < 0.0001). Furthermore, the HR-HPV group reported more anal intercourse (44% vs. 29%, p < 0.015). Multivariate analysis retained anal HR-HPV as independent risk factor for cervical HR-HPV (OR3.3, CI 1.2–9.0, p = 0.02). The results of this study emphasize that it is of upmost importance to screen women for anal HR-HPV when diagnosing cervical HR-HPV.

Full textAbstract:
Background: High-Risk Human papillomavirus (HR-HPV) has been well established as the cervical cancer (CC) risk factor. In recent years, various diagnostic methods of human papillomaviruses (HPV) have been developed to promote sensitivity and specificity of CC screening which leads to a low mortality rate. This study aimed to compare diagnostic test metrics of two HPV diagnostic techniques, including Western blot and INNO-LiPA HPV Genotyping Extra II assay methods in asymptomatic or subclinical patients, among the South-Eastern Iranian women. Methods: 323 women were referred to the Pathology and Stem Cell Research Center, from February 2018 to January 2020. HPV-DNA with the INNO-LiPA HPV Genotyping Extra-II Assay kit and the western blot assays for HPV E7 and E6 assessment were employed. Results: Overall, 163 (50.4%) samples were dysplastic pap smear, the specificity of the HPV DNA test by INNO-LiPA HPV Genotyping Extra-II Assay test was significantly higher than the E7/E6 oncoproteins finding (67.3 vs. 49.9%), and the sensitivity was lower (96.6 vs. 74.8%), respectively. Conclusions: HR-HPV E7/E6 oncoproteins expression was evaluated as a possible novel biomarker for CC screening in pap smear as the preliminary test with satisfactory diagnostic values for HR-HPV types 16 and 18. The corresponding diagnostic values may be further improved by combining HPV DNA tests with the INNO-LiPA HPV Genotyping Extra-II test. Also, they may prove helpful for HR-HPV infection diagnosis in cases that the patients are asymptomatic or subclinical.

Hypothesis:Assessment of the prevalence and type distribution of human papillomavirus (HPV) in squamous cell carcinomas (SCC) of the cervix across India was undertaken to estimate the impact of available prophylactic HPV-L1 vaccines in the country and to find out additional types that might be needed to be incorporated in second-generation vaccines.Methods:High-risk (HR) HPVs were genotyped from 667 histopathologically confirmed cases of SCC from 6 different centers representing 4 regions across India: Advanced Centre for Treatment, Research and Education in Cancer, Mumbai; All India Institute of Medical Sciences, New Delhi; Cancer Foundation of India, Kolkata; Christian Medical College, Vellore; Kidwai Memorial Institute of Oncology, Bangalore; and Regional Cancer Center, Thiruvananthapuram. Human papillomaviruses in tumor biopsies were analyzed by Xcytonscreen HPV based on PGMY09/11 multiplex polymerase chain reaction and reverse dot blot assay.Results:Overall viral prevalence across India was not different; 92.1% of 667 cases harbored HPV; 8% were negative. Infection with single HR type was seen in 86.8%: predominant types being HPV-16 followed by HPV-18, -45, -73, -31, -56, -52, -58, -59, -33, -68, -51, -35, -26, and -39. Human papillomavirus types 16/18-positive fraction formed 79.6%; other types comprised 12.4%.Conclusions:Prophylactic HPV-16/18-L1 vaccines would provide greater than 75% protection against SCC in India. Ranking and frequencies of non-16/18 types were different from earlier reports. Hence, considering the possibility of promotion of persistence of nonvaccine types in the vaccinees due to original antigenic sin and the lack of organized screening programs in India, a broad-based vaccine approach would be appropriate.

This study evaluated the clinical performance of the cobas 4800 HPV Test (Roche Molecular Systems, Pleasanton, CA, USA) for high-risk human papillomavirus (HR-HPV) testing with individual HPV-16/HPV-18 genotyping in women 21 years or older with atypical squamous cells of undetermined significance (ASCUS). Women (N = 47,208) were recruited in the United States during routine screening, and liquid-based cytology and HPV testing were performed. The ASCUS prevalence was 4.1% (1,923/47,208), and 1,578 women underwent colposcopy with valid results. The cobas 4800 HPV Test demonstrated performance comparable to the Hybrid Capture 2 test (QIAGEN, Gaithersburg, MD, USA) for the detection of cervical intraepithelial neoplasia (CIN) grade 2 or worse and grade 3 or worse. HPV-16/HPV-18+ women had a greater absolute risk of CIN 2 or worse compared with pooled HR-HPV+ and HR-HPV- women (24.4%, 14.0%, and 0.8%, respectively).The cobas 4800 HPV Test is clinically validated for ASCUS triage. HPV-16/HPV-18 genotyping can identify women at highest risk for high-grade cervical disease, and this additional risk stratification may be used in formulating patient management decisions.

Full textAbstract:
According to their oncogenic properties, Human Papillomaviruses (HPVs) are classified into two types: Low-Risk (LR-HPVs) and High-Risk Human Papillomaviruses (HR-HPVs). The immune system naturally controls the majority of HPV infections; however, when the HR-HPV infection is persistent, the risk of developing cervical cancer increases. Previous studies indicate that multiple-infection or coinfection with HR-HPV occurs frequently and can potentiate the development of cervical lesions. This study aimed to establish the HPV coinfection rate in squamous intraepithelial lesions from Mexican patients. For HPV detection, we performed PCR on 55 cervical lesions diagnosed by colposcopy. We detected the presence of HPV infection in 87.27% (48/55) of the lesions; interestingly, HPV coinfection was observed in 70.83% (34/48) of these samples. We also evaluated HPV infection in adjacent areas without morphological changes from 25 samples. The results showed that 80% (20/25) of these were HPV-positive and, curiously, all presented HPV-16 infection. In conclusion, our results revealed a high prevalence of HPV coinfection in cervical lesions in Mexican patients, and these results contribute to future research focused on the role that HPV coinfection plays in the development of cervical cancer.

Background.HIV-infected adolescents may be at higher risk for high-grade cervical lesions than HIV-uninfected adolescents. The purpose of this study was to compare the prevalence of high-risk HPV (HR-HPV) infections and Pap smear abnormalities between these two groups.Methods.In this cross-sectional study, we compared the HPV DNA and Pap smear results between 35 HIV-infected and 50 HIV-uninfected adolescents in order to determine the prevalence of HR-HPV genotypes and cervical cytological abnormalities. Comparisons were made using Pearsonχ2and independent-samplest-tests analyses, and associations between demographic and behavioral characteristics and HPV infections were examined.Results.HIV-infected participants were more likely to be infected with any HPV (88.6% versus 48.0%;P<0.001) and with at least one HR-HPV (60.0% versus 24.0%;P=0.001), and to have multiple concurrent HPV infections (68.6% versus 22.0%;P<0.001). HPV 16 and 18 were relatively underrepresented among HR-HPV infections. Abnormal Pap test results were more common among HIV-infected participants (28.8% versus 12.0%;P=0.054). A history of smoking was associated with HR-HPV infection.Conclusions.HIV-infected adolescents have an increased risk of infection with HR-HPV and of Pap test abnormalities. The majority of HR-HPV infections among our participants would not be prevented by the currently available vaccinations against HPV.

Introduction: Women infected with human immunodeficiency virus (HIV) have a higher risk of contracting human papillomavirus (HPV) infections and are more prone to develop cervical cancer. The objective of this study was to determine the prevalence of HPV and its association with risk factors among Moroccan women living with HIV/AIDS.
Methodology: We enrolled 251 HIV-infected non-pregnant women in Morocco from February 2013 to September 2016. Sociodemographic, lifestyles, behavioral and clinical data were collected. Polymerase chain reaction followed by sequencing were performed for molecular detection and HPV genotyping in cervical samples, respectively.
Results: Abnormal cervical smears were found in 34/246 patients (13.82%). The overall prevalence of HPV was 74.50%. HPV 58 was the most prevalent (39.29%) followed by HPV 18 (10.71%), HPV 70 (8.93%), HPV 33 (7.14%), HPV 6 (6.25%) and other genotypes (< 3%). Overall, high-risk HPV (HR-HPV) types were present in 75% (84/112) of patients and the prevalence of HR-HPV types in samples with abnormal Pap was higher than in normal Pap (55/83, 66.27% vs. 28/83, 33.33%, p < 0.0001). Univariate analyses showed that none of the socio-demographic and behaviors factors was associated with HPV infection. Moreover, Pap results were not affected by HPV status (p = 0.532). Whereas, CD4 T-cell counts above 200/mm3 at enrolment were apparently not protective to HPV infection. We found a high prevalence of HPV infection and HR-HPV types among HIV-positive women that significantly associated with abnormal Pap.
Conclusion: Our findings suggest a high prevalence of HPV infection with high-risk types was observed among HIV-positive women warrant to implement a regular screening by Pap smear.

Full textAbstract:
High-risk human papillomaviruses (HR-HPV) are the causal agents of an important subset of oropharyngeal cancers that has increased considerably in incidence in recent years. In this study, we evaluated the presence of HPV in 49 oropharyngeal cancers from Chilean subjects. The presence of HPV DNA was analyzed by conventional PCR, the genotypes were identified through sequencing, and the expression of E6/E7 transcripts was evaluated by a reverse transcriptase polymerase chain reaction (RT-PCR). Additionally, to determine p16 expression—a surrogate marker for oncogenic HPV infection—a tissue array was constructed for immunohistochemistry (IHC). HPV was detected in 61.2% of oropharyngeal carcinomas, the most prevalent genotype being HPV16 (80%). E6 and E7 transcripts were detected in 91.6% and 79.1% of the HPV16-positive specimens, respectively, demonstrating functional HPV infections. Furthermore, p16 expression was positive in 58.3% of cases. These findings show a high prevalence of HR-HPV in oropharyngeal tumors from Chile, suggesting the necessity of additional studies to address this growing public health concern.

Human papillomavirus (HPV) has been implicated in the etiology of a variety of human cancers. Studies investigating the presence of high-risk (HR) HPV in breast tissue have generated considerable controversy over its role as a potential risk factor for breast cancer (BC). This is the first investigation reporting the prevalence and type distribution of high-risk HPV infection in breast tissue in the population of Qatar. A prospective comparison blind research study herein reconnoitered the presence of twelve HR-HPV types’ DNA using multiplex PCR by screening a total of 150 fresh breast tissue specimens. Data obtained shows that HR-HPV types were found in 10% of subjects with breast cancer; of which the presence of HPV was confirmed in 4/33 (12.12%) of invasive carcinomas. These findings, the first reported from the population of Qatar, suggest that the selective presence of HPV in breast tissue is likely to be a related factor in the progression of certain cases of breast cancer.

ObjectiveHIV infection increases the risk of high-grade cervical neoplasia and invasive cervical carcinoma. The study addresses the limited data describing human papillomavirus (HPV) infection and cervical neoplasia among HIV-infected women in HIV-discordant relationships in sub-Saharan Africa, which is needed to inform screening strategies.MethodsA cross-sectional study of HIV-infected women with HIV-uninfected partners was conducted to determine the distribution of type-specific HPV infection and cervical cytology. This study was nested in a prospective cohort recruited between September 2007 and December 2009 in Nairobi, Kenya. Cervical cells for HPV DNA testing and conventional cervical cytology were collected. HPV types were detected and genotyped by Roche Linear Array PCR assay.ResultsAmong 283 women, the overall HPV prevalence was 62%, and 132 (47%) had ≥1 high-risk (HR)-HPV genotype. Of 268 women with cervical cytology results, 18 (7%) had high-grade cervical lesions or more severe by cytology, of whom 16 (89%) were HR-HPV-positive compared with 82 (41%) of 199 women with normal cytology (p<0.001). The most common HR-HPV types in women with a high-grade lesion or more severe by cytology were HPV-52 (44%), HPV-31 (22%), HPV-35 (22%), HPV-51 (22%) and HPV-58 (22%). HR-HPV genotypes HPV-16 or HPV-18 were found in 17% of women with high-grade lesions or more severe. HR-HPV screening applied in this population would detect 89% of those with a high-grade lesion or more severe, while 44% of women with normal or low-grade cytology would screen positive.ConclusionHR-HPV prevalence was high in this population of HIV-infected women with an uninfected partner. Choice of screening for all HR genotypes versus a subset of HR genotypes in these HIV-infected women will strongly affect the performance of an HPV screening strategy relative to cytological screening. Regional and subpopulation differences in HR-HPV genotype distributions could affect screening test performance.

Full textAbstract:
Breast cancer (BC) is the most commonly diagnosed malignancy in women worldwide as well as the leading cause of cancer-related death in this gender. Studies have identified that human papillomavirus (HPV) is a potential risk factor for BC development. While vaccines that protect against oncogenic HPVs infection have been commercially available, global disparities persist due to their high cost. Interestingly, numerous authors have detected an increased high risk (HR)-HPV infection in BC specimens when compared with non-tumor tissues. Therefore, it was suggested that HR-HPV infection could play a role in breast carcinogenesis in a subset of cases. Additional epidemiological and experimental evidence is still needed regarding the role of HR-HPV infection in the development and progression of BC.

Identifying possible negative side effects of vaccines helps to determine whether benefits outweigh the costs of a medical intervention that claims to prevent a disease. Such a cost-benefit analysis is essential both for vaccine policy as well as informed consent. This study seeks to determine whether the use of the human papillomavirus (HPV) vaccine is related to an increase in high-risk (HR), possibly cancer related, HPV infections. Data from the U.S. National Health and Examination Nutrition Survey reveal a statistically significantly higher percentage of women who received an HPV vaccine carried an HR-HPV than women who did not receive an HPV shot (Rao-Scott Chi-square contrast p-value of 0.002). Vaccine recipients tested positive less frequently for HPVs targeted by the vaccines, but had a higher prevalence of other HR (cancer related) HPVs. The results suggest that a thorough investigation of the effects of HPV vaccines on HR-HPV viruses (and other pathogens) not targeted by them is warranted.

Objectives This study aimed to: (1) Estimate HPV prevalence and genotype distribution among female sex workers (FSWs) in Mali and Benin as well as the prevalence of multiple HPV type infections in this group, and (2) Identify potential risk factors associated with high-risk (HR) HPV infections. Methods We analyzed baseline data of 665 FSWs aged ≥ 18 years recruited during a prospective cohort of cervical cancer screening in Cotonou (Benin) and Bamako (Mali) from 2017 to 2018. The Linear Array HPV genotyping test was used to identify HPV genotypes. Descriptive statistics and multivariate log-binomial regression were used. Adjusted prevalence ratios (APR) with 95% confidence intervals (95%CI) were estimated to identify risk factors associated with HR-HPV infections. Results HPV data were available for 659 FSWs (Benin: 309; Mali: 350). The mean age was 35.0 years (± 10.7) in Benin and 26.8 years (± 7.6) in Mali. The overall HPV prevalence rates were 95.5% in Benin and 81.4% in Mali. About 87.7% and 63.4% of FSWs harbored ≥ 2 HPV types in Benin and Mali, respectively. The top three prevalent HR-HPV among FSWs in Benin were: HPV58 (37.5%), HPV16 (36.6%) and HPV52 (28.8%). Corresponding patterns in Mali were HPV16 (15.7%), HPV51 (14.3%) and HPV52 (12.9%). In Benin, the main factors associated with HR-HPV were vaginal douching (APR = 1.17; 95%CI:1.02–1.34) and gonococcal infection (APR = 1.16; 95%CI:1.04–1.28), while in Mali they were sex work duration ≤ 1 year (APR = 1.35; 95%CI:1.10–1.65) and HIV infection (APR = 1.26; 95%CI: 1.06–1.51). Conclusion Our study found a very high prevalence of HPV infection as well as high frequency of multiple HPV type infections in FSWs in two countries in West Africa. These findings suggest the necessity to emphasize cervical cancer prevention in this high-risk group.

Full textAbstract:
ABSTRACT Mucosal high-risk (HR) human papillomaviruses (HPVs) that cause cervical and other anogenital cancers also are found in ∼25% of head and neck carcinomas (HNCs), especially those arising in the oropharynx and the tonsils. While many HR HPV types are common in anogenital cancer, over 90% of HPV-positive HNCs harbor HPV type 16 (HPV-16). Using a quantitative colony-forming assay, we compared the ability of full-length mucosal HPV genomes, i.e., the low-risk HPV-11 and HR HPV-16, -18, and -31, to persist in and alter the growth of primary human keratinocytes from the foreskin, cervix, and tonsils. The HR HPV types led to the formation of growing keratinocyte colonies in culture independent of the site of epithelial origin. However, HPV-18 induced colony growth in all keratinocytes >4-fold more effectively than HPV-16 or HPV-31 and >20-fold more efficiently than HPV-11 or controls. HPV-11-transfected or control colonies failed to expand beyond 32 to 36 population doublings postexplantation. In contrast, individual HR HPV-transfected clones exhibited no apparent slowdown of growth or “crisis,” and many maintained HPV plasmid persistence beyond 60 population doublings. Keratinocyte clones harboring extrachromosomal HR HPV genomes had shorter population doubling times and formed dysplastic stratified epithelia in organotypic raft cultures, mirroring the pathological features of higher-grade intraepithelial lesions, yet did not exhibit chromosomal instability. We conclude that, in culture, the HR HPV type, rather than the site of epithelial origin of the cells, determines the efficacy of inducing continued growth of individual keratinocytes, with HPV-18 being the most aggressive mucosal HR HPV type tested.

The prevalence of high-risk human papillomavirus (HR-HPV) has been reported to be three times higher in female sex workers (FSWs) in Callao, Peru than in the general population of women in Peru. Prevalence of HR-HPV among male clients has not yet been reported. A total of 150 men soliciting intercourse in sex work venues submitted questionnaires, samples for sexually transmitted infection (STI) testing, and self-collected penile samples prior to and following intercourse for HPV genotyping. We identified variables associated with pre-coital HR-HPV, and compared HR-HPV detection pre- and post-coitus. Prior to intercourse, HR-HPV prevalence was 41.9%. Married clients were less likely than unmarried clients to have HR-HPV detected ( p = 0.03). While post-coital HR-HPV prevalence was higher (47.6%), the difference was not statistically significant. However, there was a significant increase in the mean number of HR-HPV DNA strains detected before (0.75) and after (0.94) intercourse ( p = 0.02). No cases of gonorrhoea or syphilis and six (4.1%) cases of chlamydial infection were detected. Despite low prevalence of other STIs, male clients had a high HR-HPV prevalence. The increase in detection of HR-HPV following intercourse demonstrates a potential for transmission of HR-HPV despite high self-reported condom use.

Purpose. This study investigated the infection status and relationship between other common lower genital tract infectious pathogens and high-risk human papillomavirus (HR-HPV) in the high-grade cervical lesions. Methods. Overall, 882 patients were enrolled in this retrospective study, of which 339 patients (≥HSIL group) were confirmed with high-grade squamous intraepithelial lesions (HSIL) or cervical squamous cell carcinoma (SCC), while 543 patients (≤LSIL group) were diagnosed with low-grade squamous intraepithelial lesions (LSIL) or normal cervical pathology diagnosis. Cervical swab specimens were tested for HPV, pathogenic bacteria (PB), U. urealyticum (UU), M. hominis (MH), and C. trachomatis (CT) in both groups. Results. The infection rates of HR-HPV, PB, UU (at high density), and CT were higher in the ≥HSIL group than in the ≤LSIL group (P<0.001); however, higher infection rates with MH were not observed (P>0.05). PB, UU, and CT were associated with HR-HPV infection (P<0.001). The PB and UU infection rates in the ≥HSIL group were significantly different from those in the ≤LSIL group, regardless of whether there was an HR-HPV infection at the same time (P<0.05). However, this was not the case for the CT (P>0.05). Furthermore, 259 pathogenic bacterial strains were detected in 882 cases. The difference in the distribution of pathogenic bacterial flora in the different grades of cervical lesions had no statistical significance, which was prioritized over Escherichia coli (P>0.05). Conclusion. PB, UU, and CT infection is associated with susceptibility to HR-HPV, HR-HPV coinfection with these pathogens might increase the risk of high-grade cervical lesions, and PB and UU might be independent risk factors for cervical lesions.

Purpose Human papillomavirus (HPV) DNA tumors actively integrating the E6 and E7 oncogenes have a distinct biologic behavior resulting in a more favorable prognosis. To which extent the viral integration by itself, and/or the associated wild-type (wt) TP53 status, and/or a functional p16 contribute to prognosis is unclear. Patients and Methods To clarify how the presence of high-risk (HR) -HPV, TP53, and p16INK4a status interact with clinical outcome, we considered a retrospective series of 90 consecutive oropharyngeal cancer patients treated primarily with surgery. Results Seventeen (19%) patients showed integrated HPV 16 DNA (HPV positive), wt TP53 in all but two patients, normal p16INK4a in 15 assessable patients, and p16 expression in all 17 patients. Thirty-five patients (39%), two of whom were HPV positive, harbored TP53 mutations. p16INK4a deletion and p16 null immunophenotype occurred in 28 and 58 patients, respectively, and was similarly distributed in both patients with mutated TP53 (48% and 82%, respectively) and in patients with wt TP53 (46% and 77%, respectively). Statistical analysis showed that HPV-positive status significantly affects all investigated end points: overall survival (P = .0018), incidence of tumor relapse (P = .0371), and second tumor (P = .0152), whereas TP53 and p16INK4a status and p16 expression were not prognostic by themselves. Conclusion Our molecular and clinical results are in agreement with previous findings but provide additional information into the biologic mechanisms involved in HR-HPV oropharyngeal cancer in comparison to HPV-negative tumors. According to the reduced risk of relapse and second tumors associated with HR-HPV positivity of oropharyngeal cancer, the therapeutic strategy and follow-up procedures should be reviewed.

Abstract Introduction Genital human papillomavirus (HPV) infection is widespread among sexually active individuals. Several factors may contribute to increased risk of infection in pregnant women. The objective of this study was to determine the high-risk (HR-HPV) and low-risk (LR-HPV) oncogenic HPV genotypes among pregnant women in Ouagadougou. Methodology In this study, 100 endocervical samples were collected using a sterile swab on the sterile examination glove used during vaginal examination in pregnant women. DNA from each sample was amplified by PCR followed by hybridization using the HPV Direct Flow Chips kit detecting 36 HPV genotypes. Results Twenty-three percent (23%) of pregnant women had HPV infection. Of the 36 genotypes tested, 29 genotypes had been identified with a predominance of HPV 52 (10.34%), HPV 35 (6.89%), and HPV 82 (6.89%) for high risk and HPV 43 (10.34%), HPV 44/55 (6.90%), and HPV 62/81 (6.89%) for low risk. Conclusion HPV is common among pregnant women in Burkina Faso. However, the available vaccines do not cover the frequent genotypes found in this study. HPV could therefore constitute a threat for pregnant women and a risk of infection for the newborn.

Abstract Background High-risk anal human papillomavirus (HPV) infection is prevalent among men living with human immunodeficiency virus (HIV); the association between 9-valent (9v) high-risk HPV (HR-HPV) vaccine types and abnormal cytology has not been well characterized. Methods We followed a prospective cohort study of persons with HIV at 7 HIV clinics in 4 US cities from March 2004 through June 2012. Annually, providers collected separate anal swabs for HPV detection and cytopathologic examination. Among men, we examined prevalence, incidence, and clearance of 9v HR-HPV vaccine types, compared with other HR types, and associations with abnormal cytology to assess potential vaccine impact. Results Baseline prevalence of any anal 9v HR-HPV type among men who have sex with men (MSM) and men who have sex with women (MSW) was 74% and 25% (P < .001), respectively. Among 299 MSM, abnormal cytology was detected in 161 (54%) MSM and was associated with the presence of any 9v HR-HPV (relative risk [RR], 1.8 [95% confidence interval {CI}, 1.3–2.6]; P < .001). Among 61 MSW, abnormal anal cytology was detected in 12 (20%) and was associated with the presence of any 9v HR-HPV (RR, 4.3 [95% CI, 1.6–11.5]; P < .001). Conclusions Among men with HIV, the prevalence of the 7 HR-HPV types in the 9v vaccine was high and was associated with abnormal cytology. These findings indicate that men with HIV could benefit from prophylactic administration of the 9v HPV vaccine.

Even when receiving combination antiretroviral therapy, women living with HIV are at high risk of human papillomavirus (HPV) infection and/or cervical lesions, including cancer. Using data from the PapilloV prospective cohort, we evaluated the prevalence of high-risk HPV (HR-HPV) infections after cervical lesion treatment and investigated factors associated with their carriage. Women were followed up for three years with annual Pap smear and HPV genotyping. We offered treatment to women presenting either a Pap smear with high-grade squamous intraepithelial lesion or higher, and/or a biopsy showing cervical intraepithelial neoplasia II or III. We compared the prevalence of HR-HPV infection at the time of first treatment indication and at the end of follow-up among women who received treatment and those who did not. Overall, 46 women had treatment indication. HR-HPV prevalence significantly decreased from 67% to 27% (p value = 0.001) in the 30 women who received treatment, while it did not significantly decrease (from 56% to 38%) in the 16 women who did not (p value = 0.257). Due to lack of statistical power, the 40% relative difference in HR-HPV carriage between treated and untreated women was not significant. In women living with HIV, the treatment of a cervical lesion may be beneficial for clearing HR-HPV infections.

ObjectivesThis 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.DesignThis 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.SettingThis study was conducted in Sheffield, UK, between April 2013 and August 2014.ParticipantsSeven 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).InterventionsParticipants 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 measuresThe 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.ResultsThe 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.ConclusionsThe 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 numberID14106.

Human Papillomavirus (HPV) is a species specific double-stranded DNA virus infecting human cutaneous or mucosal tissues. The genome structure of HPV is extremely polymorphic hence making it difficult to discriminate between them. HPV exhibits numerous dissimilar types that can be subdivided into high-risk (HR), probably high-risk and low-risk (LR), causing numerous types of cancers and warts around the genital organs in humans. Several screening methods are performed in order to detect cytological abnormalities and presence or absence of HPV genome. Currently available commercial kits and methods are designed to detect only a few HR/LR-HPV types, which are expensive adding to the economic burden of the affected individual and are not freely available. These gaps could be minimized through Polymerase Chain reaction (PCR) method, which is a gold standard and a cost-effective technique for the detection of most HPV (both known and unknown) types by using specific consensus primers in minimal lab setup. In this context, numerous studies have validated the effectiveness of different sets of consensus primers in the screening of HPVs. Numerous consensus primers, such as E6, E6/E7, GP-E6/E7, MY09/11, GP5+/GP6+, SPF10, and PGMY09/11 have been developed to detect the presence of HPV DNA. In addition, HPV detection sensitivity could be achieved through consensus primer sets targeting specific ORF regions like L1 and E6, which may finally assist in better diagnosis of several unknown HR-HPVs. The present review, provides a summary of the available methods, kits and consensus primer sets for HPV genome based detection, their advantages and limitations along with future goals to be set for HPV detection.

Women living with HIV (WLHIV) are prone to harbor several high-risk human papillomavirus (HR-HPV) genotypes and to develop cervical cancerous lesions. Data on HPV prevalence in these women are needed to inform immunization programs, especially in Asia where few data are available. We conducted a systematic review and meta-analysis to estimate the prevalence of HPV and HR-HPV cervical infection in WLHIV in Asia and identify possible sources of heterogeneity for HR-HPV carriage. Pooled prevalence and its 95% confidence interval (95CI) were estimated using the inverse-variance weighting method. Linear regression weighted on study size was used to identify sources of heterogeneity. Among 7834 WLHIV (40 studies), the prevalence of HPV infection was 42.6% (95CI, 38.2% to 47.1%), and 34.6% (95CI, 30.3% to 39.1%) harbored HR-HPV genotypes, with significant heterogeneity across countries. In India, Thailand, and China, HPV-16 was the most frequent genotype (10.3%), followed by HPV-52 (5.4%), HPV-58 (5.0%), HPV-18 (4.1%), and HPV-33 (3.3%). In these women, most of whom were receiving antiretroviral therapy, we did not identify determinants of heterogeneity for HR-HPV infection. Our results underline the need for immunization programs based on nonavalent or new generation vaccines to prevent cervical cancer in WLHIV in Asia.

Introduction: Human papillomavirus (HPV) is frequently a sexually transmitted virus and can cause cervical cancer in women. Cervical cancer is the second most common type of cancer among the developing countries. In this study, cervical HPV DNA positivity and genotype distributions were investigated in female patients living in our region and the results were compared with different studies. Materials and Methods: Between 1 July, 2017 and 1 March, 2019, 433 cervical swabs were sent to Ataturk University, Medical Faculty Hospital, Medical Microbiology Laboratory due to suspicion of HPV. Swab samples were evaluated for HPV virus using molecular (Polymerase Chain Reaction-PCR) methods. For this purpose, Xpert HPV Test (Cepheid, Inc, Sunnyvale, CA) was used to identify HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 t in a single sample. Results: Mean age of the patients ranged from 20 to 69 years, with a mean of 39.8 years (± 10.0). Positivity was detected in 62 of the 433 patients. Mean age of the positive patients was 40.2 years (± 11.3). When the positive patients were examined in terms of HPV types, the presence of HPV 16 was observed with a rate of 25.6%, while the HPV 18/45 types were found to be 9.0% in total. When patients were evaluated according to age groups, HPV DNA positivity was highest in the 25-34 age group with 38.7%. In our statistical study, there was no significant difference in HPV DNA positivity rate between the ages of 35 and under 35 years. Conclusion: This study demonstrates the prevalence and viral genotype distribution of HPV infection in women in Erzurum region. HPV type 16 is seen with a high rate in our region.

Full textAbstract:
Context.— Detection of high-risk human papillomavirus (HR-HPV) in squamous cell carcinoma is important for classification and prognostication. In situ hybridization (ISH) is a commonly used HR-HPV–specific test that targets viral RNA or DNA. The College of American Pathologists (CAP) provides proficiency testing for laboratories performing HR-HPV ISH. Objective.— To compare the analytical performance of RNA- and DNA-based ISH methods on CAP HR-HPV proficiency tests. Design.— Data from the 2016–2018 CAP HPV ISH proficiency testing surveys were reviewed. These surveys consist of well-characterized samples with known status for HR-HPV, including 1 to 2 copies, 50 to 100 copies, 300 to 500 copies, and no copies of HR-HPV per cell. Results.— Ninety-five participants submitted 1268 survey results from 20 cores. Overall, RNA ISH had a significantly higher percentage of correct responses than DNA ISH: 97.4% (450 of 462) versus 80.6% (650 of 806) (P < .001). This disparity appears to be the consequence of a superior sensitivity of RNA ISH compared to DNA ISH for samples with 1 to 2 and with 50 to 100 copies of HR-HPV per cell: 95.2% (120 of 126) versus 53.8% (129 of 240), P < .001, respectively, and 100% (89 of 89) versus 76.3% (119 of 156), P < .001, respectively. Conclusions.— An assessment of CAP HR-HPV proficiency test performance indicates that RNA ISH shows significantly higher accuracy than DNA ISH owing to higher analytical sensitivity of RNA ISH in tumors with low (1–2 copies per cell) to intermediate (50–100 copies per cell) HR-HPV viral copy numbers. These data support the use of RNA over DNA ISH in clinical laboratories that perform HR-HPV testing as part of their testing algorithms.

In Botswana, where human immunodeficiency virus (HIV) prevalence remains high, cervical cancer is the leading cause of cancer deaths in women. Multiple organizations recommend high-risk human papillomavirus (hr-HPV) testing as a screening tool; however, high coverage may not be feasible with provider-collected samples. We conducted the first assessment of self- versus provider-collected samples for hr-HPV testing in HIV-positive women in Botswana and report prevalence of hr-HPV and histological outcomes. We recruited HIV-positive women ≥25 years attending an HIV clinic in Gaborone. Self- and provider-collected samples from participants were tested for hr-HPV using Cepheid GeneXpert. Women testing positive for any hr-HPV returned for colposcopy. We used unweighted κ statistics to determine hr-HPV agreement. We report that 31 (30%) of 103 women tested positive for any hr-HPV. The most common genotypes were HPV 31/33/35/52/58. Overall agreement between self- and provider-collected samples for any hr-HPV was 92% with a κ of 0.80. Ten of the 30 hr-HPV-positive women attending colposcopy had CIN2+ (33%). In conclusion, in this HIV-positive population, there was excellent agreement between self and provider samples, and self-sampling may play an important role in screening programs in high HIV burden settings with limited resources like Botswana.

Full textAbstract:
Esophageal cancer is a relatively common malignancy worldwide with a high mortality (5-year survival of <15%). Despite screening, surveillance, improved imaging and treatment, the exponential rise in OAC continues. The strongest risk factors for OAC are chronic heartburn and metaplastic transformation of the lower third of the esophagus (Barrett’s esophagus). The risk profile includes Caucasian race, male gender older age, obesity and smoking. Although the tumor risk in BO has been progressively revised downwards, the exponential rise in OAC remains unchecked. This paradox points to an unidentified missing link. Relatively recently, we provided the world’s initial data for a strong association of biologically relevant hr-HPV with BD and OAC. Since then, systematic reviews and meta-analysis have documented HPV DNA prevalence rates in OAC of between 13 to 35%. In this review, we provide some evidence for a probable causal relationship between hr-HPV and OAC. This is challenging given the multifactorial etiology and long latency. Increasingly, high-risk HPV (hr-HPV) is regarded as a risk factor for OAC. This discovery will aid identification of a sub-group of high-risk progressors to esophageal cancer by surveillance and the development of effective preventive strategies including vaccination.

Full textAbstract:
High-risk human papillomaviruses (HR-HPVs) and Epstein–Barr virus (EBV) are recognized oncogenic viruses involved in the development of a subset of head and neck cancers (HNCs). HR-HPVs are etiologically associated with a subset of oropharyngeal carcinomas (OPCs), whereas EBV is a recognized etiological agent of undifferentiated nasopharyngeal carcinomas (NPCs). In this review, we address epidemiological and mechanistic evidence regarding a potential cooperation between HR-HPV and EBV for HNC development. Considering that: (1) both HR-HPV and EBV infections require cofactors for carcinogenesis; and (2) both oropharyngeal and oral epithelium can be directly exposed to carcinogens, such as alcohol or tobacco smoke, we hypothesize possible interaction mechanisms. The epidemiological and experimental evidence suggests that HR-HPV/EBV cooperation for developing a subset of HNCs is plausible and warrants further investigation.

Background: The purpose of this study is to investigate the effect of an adsorbent-antioxidant vaginal gel, which contains micronized silicon dioxide and antioxidant deflamin, on high-risk human papillomavirus (hr-HPV) clearance within the follow-up periods specified in the guidelines. Methods: In the study, the data of 52 patients infected with hr-HPV using vaginal gel for 3 months and 115 patients who were not using vaginal gel were analyzed retrospectively. Demographic characteristics, Liquid-Based Cytology (LBC) at the time of presentation, colposcopy findings, and cervical biopsy results of both groups were investigated. After the LBC and hr-HPV results were evaluated at the end of the control period, both groups were compared in terms of hr-HPV clearance. The level of statistical significance was taken as 0.05 in all tests. Results: The two groups had similar demographic data, cytological findings, colposcopy findings, and cervical biopsy results (p > 0.05). During similar follow-up periods (13.6 ± 3.2 vs. 14.1 ± 3.4 months; p > 0.05), there was no significant difference in terms of hr-HPV clearance (46.2% vs. 51.3%; p > 0.05). Furthermore, the initial and follow-up cytology results of the patients were similar (p > 0.05).

SUMMARYThe aim of the study was to estimate the prevalence and risk factors associated with infection by high-risk human papillomavirus (HR-HPV) in cervix and squamous intra-epithelial lesions (SIL) in imprisoned women. This was done by a cross-sectional study of imprisoned women attending the gynaecological clinic in Foncalent prison in Alicante, Spain. The study period was from May 2003 to December 2005. HR-HPV infection was determined through Digene HPV Test, Hybrid Capture II (HC-II). HPV typing was determined by multiplex nested PCR assay combining degenerate E6/E7 consensus primers. Multiple logistic regression modelling was used for the analysis of associations between variables where some were considered possible confounders after checking for interactions. A total of 219 women were studied. HR-HPV prevalence was 27·4% and prevalence of SIL was 13·3%. HIV prevalence was 18%, higher in Spaniards than in migrant women (24·6%vs. 14·3%,P<0·05). In multivariate analyses, risk factors for HPV infection were younger age (Pfor trend=0·001) and tobacco use (OR 2·62, 95% CI 1·01–6·73). HPV infection (OR 4·8, 95% CI 1·7–13·8) and HIV infection were associated with SIL (OR 4·8, 95% CI 1·6–14·1). The commonest HPV types were HPV16 (29·4%), HPV18 (17·6%), HPV39 (17·6%) and HPV68 (17·6%). The prevalence of both HR-HPV infection and SIL in imprisoned women found in this study is high. Determinants for each of the outcomes studied were different. HPV infection is the most important determinant for SIL. A strong effect of HIV co-infection on the prevalence of SIL has been detected. Our findings reinforce the need to support gynaecological clinics in the prison setting.

Objectives. Most of human papillomavirus (HPV) infections are “cleared” by the immune system; however, in cases of immune system suppression, infections could lead to development of malignancies. The aim of this study was to find out the frequency of HR-HPV infection in early period after renal transplantation in recipients receiving immunosuppressive therapy and to follow the progression of the infection up to one year. Methods. 43 female renal transplant recipients and 79 healthy female individuals as a control group were enrolled in this investigation. For the detection of HPV infection, patients’ samples (blood and vaginal swabs) were collected two weeks after transplantation with following collection of six months and one year. Different polymerase chain reactions for HR-HPV genomic sequences detection and ELISA kit for detection of anti-HPV IgG antibodies were used. Results. In this study, we show that frequency rate of HR-HPV infection has increased in the first year after transplantation from early stage of immunosuppressive therapy (from 24% to 36%). Also an increase of HR-HPV load was detected over time, showing the highest median viral load at sixth month after transplantation. Conclusions. From the obtained data, it follows that it is very important to carefully monitor patients receiving immunosuppression therapy on progression of HR-HPV.

Nowadays, the striking numbers of infertile couples that turn to assisted reproductive technologies (ART) drive the research toward a more comprehensive understanding of the underlying causes. Male factors contribute to the inability to conceive in half of the cases, and it has been suggested that sexually transmitted infections could have a role in the onset of spermatozoa impairments. Since the impact of HPV infection on sperm quality and sperm DNA integrity is debated, we wanted to analyze its impact on conventional seminal parameters and the sperm DNA fragmentation index (DFI). Therefore, 117 semen samples of patients undergoing IVF were evaluated for the following characteristics: HPV DNA detection and sperm DNA fragmentation, concentration, motility, and morphology. The results showed a higher rate of HPV-negative patients (59.8% vs. 40.2%) and no HPV-related effect on DFI, sperm concentration, total sperm number, and total motility. Only progressive motility and morphology were found as significantly influenced by HPV positivity. Moreover, we observed a statistically significant difference in DFI when comparing high-risk HPV (HR-HPV) and low-risk HPV (LR-HPV) genotypes. Our data suggest that the presence of any HPV type, whatever the exact localization of the virions, can impair some sperm parameters, while HR-HPVs specifically affect the integrity of spermatozoa DNA.
