Background: In the Netherlands, bivalent human papillomavirus (HPV) vaccination was included in the National Immunization Program for 12-year-old girls in 2010 (vaccination coverage, 45%–60%). We examined possible changes in HPV seroprevalence in the HPV-unvaccinated Dutch population aged 0–89 years, comparing prevaccination data with data of approximately 6 years after implementation of national vaccination. Methods: Serum samples of men and women were used from two cross-sectional population-based serosurveillance studies performed before (2006–07, n = 6,384) and after (2016–17, n = 5,645) implementation of HPV vaccination in the Netherlands. Seven high-risk HPV-specific antibodies (HPV16, 18, 31, 33, 45, 52, and 58) were tested in a virus-like particle-based multiplex immunoassay. Results: Type-specific HPV seroprevalence increased in women between 2006–07 and 2016–17. Also, a higher seroprevalence for at least one type in women >15 years was found in 2016–17 (31.7%) compared with 2006–07 (25.2%). In men, overall HPV seroprevalence remained similar; however, a lower seroprevalence was found for HPV16 in 2016–17 (7.5%) compared with 2006–07 (10.6%). Conclusions: Our results indicate an increase in high-risk HPV types in women and a rather stable exposure in men. No clear effects of the strategy of girls-only vaccination were observed in men, probably because of the short time after introduction combined with suboptimal coverage. Impact: No herd immunity has been observed yet in a population with suboptimal HPV vaccination coverage.

OBJECTIVE This systematic review and meta-analysis aimed to evaluate the risk of malignant sinonasal inverted papilloma (SNIP) according to the type of human papilloma virus (HPV) infection. METHODS The databases of PubMed, EmBase, and Web of Science were searched for studies that reported the risk of malignant SNIP in patients infected by specific types of HPV. The quantitative analyses for pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS Twenty-six molecular epidemiological studies that recruited a total of 900 patients with SNIP were selected for the final meta-analysis. The summary ORs indicated that HPV-6 (OR: 2.02; 95% CI: 0.47-8.61; P = .343), HPV-11 (OR: 0.86; 95% CI: 0.26-2.89; P = .806), and HPV-6/11 (OR: 1.44; 95% CI: 0.59-3.53; P = .426) infections were not associated with the risk of malignant SNIP. However, the risk of malignant SNIP was increased in patients infected with HPV-16 (OR: 8.51; 95% CI: 3.36-21.59; P

OBJECTIVES: Self-sampling may increase access to cervical cancer screening in low-resource settings. Using Xpert HPV, we compared test performance of self- and clinician-collected samples in HIV-positive and HIV-negative women in South Africa. MATERIALS AND METHODS: Three hundred thirty HIV-positive and 375 HIV-negative women in the screening group and 202 HIV-negative and 200 HIV-positive women in the referral group, aged 30–65 years, participated in the study. All women self-collected a vaginal sample, and then, a cervical sample was collected by a clinician (both tested using Xpert HPV), followed by colposcopic examination and collection of histologic specimens. RESULTS: There was good agreement between self- and clinician-collected samples for detection of any high-risk human papillomavirus (HPV, κ = 0.72 [95% CI = 0.669–0.771]). Prevalence of HPV and sensitivity of the test to detect cervical intraepithelial neoplasia 2+ was similar in self- and clinician-collected samples. Specificity was lower in self-collected than in clinician-collected samples in both HIV-negative (self: 77.5% [95% CI = 72.8–81.8] vs clinician: 86.9% [95% CI = 82.9–90.2]) and HIV-positive (self: 44.0% [95% CI = 38.0–50.1] vs clinician: 59.7% [95% CI = 53.6–65.6]) women. Restricting the definition of screen-positive to 3 of 5 channels on HPV Xpert improved specificity in both HIV-negative (self: 83.2% [95% CI = 78.8–87.0] vs clinician: 89.7% [95% CI = 86.1–92.7]) and HIV-positive (self: 54.2% [95% CI = 48.1–60.2] vs clinician: 67.4% [95% CI = 61.5–72.9]) women. CONCLUSIONS: The self-collected sample had good agreement with the clinician-collected sample for the detection of HPV, and restricting the HPV types may improve the specificity in HIV-positive women.

Background A few studies of Human Papillomavirus (HPV) distribution and frequency have shown a real context of infection in men. The study aimed to know the HPV types distribution in men from Northwestern Mexico, in general, per age and year. Methods A total of 1,769 males were recruited from 5 years (2011–2015), from an HPV PCR testing laboratory service. Penile scraps from urethral meatus and coronal sulcus were taken for DNA isolation. There were detected 32 high and low-risk HPV types by HPV Type 3.5 LCD-Array system. Results A high frequency of HPV-6 and HPV-66 and a reduced frequency of HPV-18 and HPV-11 was detected. Young men had a high risk of HPV infection regarding men aged 40 years and older. The theoretical coverage for the HPV vaccine in men was calculated, where the bivalent vaccine showed coverage of 21.66% in high-risk HPV positive cases. Conclusion The men from Northwestern Mexico have a different distribution of high and low-risk HPV types and high risk of HPV infection in younger men, with a theoretical coverage for HPV bivalent vaccine of 1 of 10 positive men for any HPV type.

Background Human papillomavirus (HPV) is a necessary cause of cervical cancer, although some invasive cervical cancers may test negative by HPV PCR. We previously requested all invasive cervical cancers in Sweden during 10 years and subjected them to PCR. We also optimised methods for deep sequencing of formalin-fixed paraffin-embedded samples. Methods Using Novaseq 6000, we simultaneously sequenced total DNA and cDNA from 392 HPV PCR-negative cervical cancers. Non-human reads were queried against all known HPVs. The complete database now contains PCR and/or deep sequencing data on 2850 invasive cervical cancers. Results HPV sequences were detected in 169/392 of HPV PCR-negative cervical cancers. Overall, 30 different HPV types were detected, but only 5 types were present in proportions above 3% of cancers. More than 92% of tumours were HPV-positive in PCR and/or sequencing (95% confidence interval: 91.1–93.1%). Exploring possible reasons for failure to previously detect HPV suggest that more sensitive type-specific PCRs for HPV 31, 33, 45 and 73 targeting retained regions of HPV would have detected most of these (117/392). Conclusions Unbiased deep sequencing provides comprehensive data on HPV types in cervical cancers and appears to be an important tool for quality assurance of HPV screening.

All cancer-causing human papillomavirus (HPV) E6 oncoproteins have a C-terminal PDZ-binding motif (PBM), which correlates with oncogenic potential. Nonetheless, several HPVs with little or no oncogenic potential also have an E6 PBM, with minor sequence differences affecting PDZ protein selectivity. Furthermore, certain HPV types have a phospho-acceptor site embedded within the PBM. We therefore compared HPV-18, HPV-66 and HPV-40 E6 proteins to examine the possible link between the ability to target multiple PDZ proteins and the acquisition of a phospho-acceptor site. The mutation of essential residues in HPV-18E6 reduces its phosphorylation, and fewer PDZ substrates are bound. In contrast, the generation of consensus phospho-acceptor sites in HPV-66 and HPV-40 E6 PBMs increases the PDZ proteins recognized. Thus, although phosphorylation of the E6 PBM and PDZ protein recognition are mutually exclusive, they are closely linked, with the acquisition of a phospho-acceptor site also contributing to an expansion in the number of PDZ proteins bound.

This article is a preliminary investigational study that is aimed at giving hints about the interesting biomarkers involved in the transition process from low-grade cervix lesion to invasive cervical cancer. Our study focuses on the risk factors and tumour molecular changes in one patient. First in 1986, she was diagnosed a preinvasive cervix lesion. Then, 16 years later, she was diagnosed an invasive cervical cancer. The 2002 diagnosis was a squamous cell carcinoma of the cervix, stage IIIB (FIGO), whereas in 1986, she had been diagnosed a high-grade squamous intraepithelial cervical lesion. Retrospectively, the analysis of samples of preneoplastic lesions and invasive cervical cancer confirmed the histopathological diagnoses and detected the presence of HPV type and HPV-16 variants, as well as the overexpression of proteins such as hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1. Finally, the Arg72Pro polymorphism was detected in TP53. The role of high-risk HPV and HPV-16 variants and of hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1 variations seemed confirmed in the development and progression of cervical cancer. As a result, analyzing the molecular changes in one and same tumour that progresses from a low-grade cervix lesion to invasive cervical cancer could provide valuable information in order to improve detection, diagnosis, and treatment in the future.

To study the interaction between HIV and other carcinogenic infections in conjunctival squamous cell carcinoma (SCC), we evaluated the presence of a broad spectrum of human viruses in conjunctiva specimens. Beta Human papillomavirus (HPV; n = 46), gamma HPV (n = 52), polyomaviruses (n = 12) and herpes viruses (n = 3) was determined in DNA extracted from 67 neoplastic and 55 non-neoplastic conjunctival tissues of HIV-positive and HIV negative subjects by Luminex-based assays. Next-generation sequencing (NGS) was also used to further characterize the presence of cutaneous HPVs. Detection of beta-2 HPV infections was associated with the risk of neoplasia (adjusted odds ratio [aOR] 3.0; 95% confidence interval [CI] 1.3-6.8), regardless of HIV status (HIV positive, aOR 2.6, 95% CI 0.9-7.7; HIV negative, aOR 3.5, 95% CI 0.9-14.4). EBV was strongly associated with the risk of neoplasia (aOR 12.0, 95% CI 4.3-33.5; P < .01) mainly in HIV individuals (HIV positive, aOR 57.5; 95% CI: 10.1-327.1; HIV negative aOR 2.6; 95% CI: 0.2-34.7). NGS allowed to identify 13 putative novel HPVs in cases and controls. Our findings suggest a role of beta HPV types and EBV, in conjunctival SCC. However, additional studies of viral expression in tumor tissue are required to confirm the causal association.

OBJECTIVE Micronuclei counts were performed in cervical smears with low-grade squamous intraepithelial lesions of the cervix (LSIL) to assess its potentiality as tumour marker in cervical carcinogenesis. METHODS The cases studied were from the ongoing rural cervical cancer screening in west Lucknow, India. Micronuclei counts were performed in the cervical smears of 100 LSIL cases, and the number of cells with micronuclei was defined as micronucleated cells (MNC) and the number of micronuclei per 1000 cells as MNC score. Human papillomavirus (HPV) DNA testing was also done in 100 LSIL cases by GeneNav qPCR test. RESULTS A high MNC score was found in 20 of the 100 LSIL cases while the counts were low in the remaining 80. Persistence of LSIL was seen in 19 of the 20 LSIL cases with high MNC score while only six cases of the 80 cases with low MNC score showed persistence. The persistence of LSIL was very high in cases with high MNC score. The multiple high-risk HPV types such as 18, 31, 33 and 35 were seen in 12 of the 100 LSIL cases and a high positivity rate was seen in women with high MNC score. The persistence of LSIL was also higher with HPV positivity. CONCLUSION The study revealed correlation between high MNC score, persistence of LSIL and HPV positivity. Hence, MNC score can prove to be very useful in discriminating high-risk LSIL cases that are less likely to regress and possibly may progress to high-grade squamous intraepithelial lesions or carcinoma.

Objective To describe prevalent and persistent oncogenic human papillomavirus (HPV) types detected in women living with HIV (WLWH) in Canada, including women with cervical dyskaryosis, and to determine predictors of type-specific HPV persistence. Methods Women and girls living with HIV, recruited from 14 sites of HIV care across Canada, were included in a sub-analysis of a prospective vaccine immunogenicity cohort study (two HPV DNA results, at least one cervical cytology result pre-vaccination). Demographic and clinical data were collected alongside cervical samples for cytology and HPV DNA typing between November 25, 2008, and May 19, 2015. Results Pre-vaccination, HPV16 and HPV52 were the most prevalent oncogenic HPV types. Of the 252 women and girls who met the eligibility criteria, 45% were infected with at least one oncogenic HPV type and one-third of participants had a persistent oncogenic infection. HPV16, 45, and 52 were the most frequently persistent types. Seventeen percent of women had persistent infections with oncogenic HPV types not within currently available vaccines (HPV35/39/51/56/59/68/82). Lower CD4 count significantly predicted HPV persistence (P=0.024). Cervical cytology results were normal for 82.9% of participants, atypical squamous cells of undetermined significance for 2.4%, low-grade squamous intraepithelial lesions for 11.5%, and high-grade squamous intraepithelial lesions for 2.8%. Conclusion Unvaccinated WLWH were infected with a wide range of oncogenic HPV types. The findings highlighted the importance of optimal treatment of HIV and continued cervical cancer screening as key steps toward the global elimination of cervical cancer.

ObjectiveThe objective of the present study was to assess the prevalence and type-specific distribution of cervical high-risk (HR) human papillomavirus (HPV) among women with normal and abnormal cytology, and to describe risk factors for HR HPV among HIV-positive and HIV-negative women in Tanzania.MethodologyA cross-sectional study was conducted in existing cervical cancer screening clinics in Kilimanjaro and Dar es Salaam. Cervical specimens were obtained from women aged 25–60 years. Samples were shipped to Denmark for cytological examination, and to Germany for HR HPV testing (using Hybrid Capture 2) and genotyping (using LiPaExtra). Risk factors associated with HPV were assessed by multivariable logistic regression analysis.ResultAltogether, 4080 women were recruited with 3416 women contributing data for the present paper, including 609 HIV-positive women and 2807 HIV-negative women. The overall HR HPV prevalence was 18.9%, whereas the HR HPV prevalence in women with high-grade squamous intraepithelial lesions (HSILs) was 92.7%. Among HPV-positive women with HSIL, HPV16 (32.5%) and HPV58 (19.3%) were the the most common types followed by HPV18 (16.7%) and HPV52 (16.7%). Factors associated with HR HPV included younger age, increasing number of partners and early age at first intercourse. Similar risk factors were found among HIV-positive and HIV-negative women. In addition, among HIV-positive women, those with CD4 counts 3 had an increased risk of HR HPV (OR 2.2; 95% CI 1.2 to 4.8) compared with individuals with CD4 count ≥500 cells/mm3.ConclusionGiven the HPV distribution among Tanzanian women, the current HPV vaccination in Tanzania using quadrivalent vaccine may be considered replaced by the nonavalent vaccine in the future. In addition, appropriate antiretroviral treatment management including monitoring of viremia may decrease the burden of HR HPV in HIV-positive women.

Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide and a necessary condition for cervical cancer (CeCa) development. HPV types 16 and 18 are the most common in cervical lesions (CLs); therefore, specific vaccines have reduced cervical neoplasia. In 2015, HPV16 presented the highest frequency in CLs (~ 28%); however, types 31, 45, 52, and 58 were also detected, suggesting that other HPV types may have impact on healthcare. Here, we typified 30 patients with CLs from the “Hospital Regional 1° de Octubre” (HR1O), in Mexico City, for the most reported high-risk papillomavirus (HPV16, 18, 31, 33, 45, 58, and 59). The results showed that HPV16 frequency is dissimilar to international and previous national data, suggesting that a deeper knowledge of HPV type distribution is required before choosing a vaccination scheme for HPV in Mexico City.

The objective was to evaluate the participation rate of a free of charge vaginal self-sample (Aptima multitest swab, Hologic) for the detection of human papillomavirus (HPV) in an Ethiopian cohort. PATIENTS AND METHODS: Specimens were collected from women employed by Ethiopian Airlines in Addis Abeba (N=5950). Samples were analysed for the presence of high-risk (HR) HPV mRNA by the Aptima HPV assay (Hologic) and HPV positive women were referred for cytology. Identification of HPV types among HPV positive samples was performed by Modified general primer-PCR and Luminex assay. RESULTS: Participation rate was 3.1% and the prevalence of HPV mRNA was 20.6% (37/180). CONCLUSION: Primary HPV mRNA screening with vaginal self-sampling may be an acceptable approach in Ethiopia. One out of five women harbor HPV in their vaginal self-sample in agreement with other similar studies from the region. (Less)

To evaluate the prevalence of human papillomavirus (HPV) infection and its genotype among women with cervical lesions in Henan Province, central China. A total of 1317 cervical scrapes from patients with cervical intraepithelial neoplasia 1 (CIN1) (n = 91), CIN2/3 (n = 466), and cervical cancer (CC; n = 760) were collected from 2013 to 2018, and then tested for HPV genotypes using polymerase chain reaction followed by flow-through hybridization assay. The prevalence of HPV was 62.64% for patients with CIN1, 86.91% for patients with CIN2/3%, and 89.21% for patients with CC. In total, the HPV prevalence was 86.56%, and the most common HPV type was HPV16 (58.77%) followed by HPV58 (10.33%), 18 (7.67%), 52 (6.61%), and 33 (5.54%). In this study, the high-risk HPV cumulative attribution rate of nine-valent vaccine coverage was markedly higher than that of bivalent or quadrivalent vaccine coverage in each histopathological category or overall (P

br /Using HPV testing to triage ASC-US still has some problems of unnecessary colposcopy in many cases. A previous study reported that methylation of CCNA1, a tumor suppressor gene, can differentiate between low and high grade lesions. This study was designed to evaluate the diagnostic values and application of CCNA1 methylation in the patients with ASC-US group.br /Materials and methods:br /Cross sectional analytic study was conducted in the patients withbr /ASC-US cytology. HPV DNA testing and CCNA1 promoter methylation testing were performed. The patients were sent for colposcopic examination and biopsy. Biopsy results were considered as gold standard. Diagnostic test of HPV test and CCNA1 methylation test were calculated for sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), likelihood ratio for test positive and negative and 95% confidence interval.br /Results:br /One hundred and seventy patients were enrolled. Mean age was 39.7 years old. HR-HPV was positive in 70% of the patients. HPV type 16, type 18 and non-16,18 were 12.4%, 4.7% and 42.4%, respectively. CIN2+ were found in 12.4% (21 cases). CCNA1 promoter methylation was positive in 5 cases. CCNA1 had high specificity 99.3%, NPV 89.2% and PPV 80% in detection of CIN2+ but sensitivity was 19%. Likelihood ratio for positive test was 28.4 and likelihood ratio for negative test was 0.8. HPV test had sensitivity of 90.5% and NPV of 95.9% but low specificity and PPV as 31.5% and 15.7%, respectively.br /Conclusion:br /CCNA1 promoter methylation testing had very high specificity, likelihood ratio for the positive test and PPV (99.3%, 28.4 and 80.0, respectively). Therefore, CCNA1 promoter methylation test may be used in the HPV DNA positive cases to classify the urgency of colposcopy and the colposcopist should pay more attention to CCNA1 positive patients because of their higher chance to identify the significant lesions.

espanolIntroduccion. El virus del papiloma humano (VPH) es la principal causa de cancer cervical. La etiologia y los efectos derivados de esta infeccion se establecen mediante tecnicas moleculares y diagnostico citologico, respectivamente. En el presente estudio, los datos obtenidos por un cribado oportunista de cancer cervical en la comarca de La Ribera se revisaron y se relacionaron estadisticamente. Material y metodos. Se recopilaron datos que incluyeron diferentes variables como la edad, el grado de lesion, el tipo de VPH detectado y el numero de virus en coinfeccion de 1.372 citologias positivas para VPH. La deteccion del VPH se realizo mediante tres tecnicas moleculares y el grado de lesion se analizo mediante diagnostico citologico (Bethesda). Para determinar la relacion entre las diferentes variables, se realizaron varios analisis estadisticos. Resultados. Solo la variable del grado de lesion mostro una relacion directa con el resto de variables, aumentando con el proceso de envejecimiento, la oncogenicidad viral, la presencia de al menos un virus de alto riesgo y el hecho de estar mono-infectado. La probabilidad de presentar un mayor nivel de lesion se multiplico por 28,4 cuando se detecto VPH de alto riesgo en la mono-infeccion. Conclusiones. La deteccion molecular del VPH es la tecnica mas adecuada para realizar un cribado primario del cancer de cuello uterino para el manejo de mujeres con diagnostico citologico negativo. El numero de tipos detectados esta estadisticamente relacionado con el grado de lesion. El establecimiento de un cribado regulado adecuadamente para identificar la infeccion por VPH y, por lo tanto, del riesgo de cancer cervical, es esencial. EnglishIntroduction. Human Papillomavirus (HPV) is the main cause of cervical cancer. The etiology and effects derived from this infection are set by molecular techniques and cytological diagnosis, respectively. In the present study, data obtained by an opportunist screening of cervical cancer in La Ribera region are revised and related statistically. Material and methods. Data considering different variables such as age, degree of lesion, HPV type detected and number of virus in coinfection were collected from 1,372 HPV positive cytology samples. HPV detection was carried out by means of three molecular techniques and the degree of lesion was analyzed by cytological diagnosis (Bethesda). In order to determine the relationship between different selected variables, several statistical analyses were performed. Results. Only degree of lesion variable showed a direct relationship with the rest of variables, increasing with aging process, viral oncogenicity, presence of at least one high-risk virus and with the fact of being mono-infected. The probability of presenting a higher-level degree of lesion multiplied by 28.4 when high-risk HPV was detected in mono-infection. Conclusions. HPV molecular detection is the most suitable technique to perform a cervix cancer primary screening for the management of women with negative cytological diagnose. The number of detected types is statistically related to the degree of lesion. The establishment of a properly regulated screening to identify HPV infection, and therefore, of cervical cancer risk, is essential.

Introduction: Warts are benign proliferations of skin and mucosa caused by the human papillomavirus (HPV). Palmoplantar warts are caused any HPV types 1, 2, 4, 27, 57 and occurs mostly in children and young adults. Among the treatment modalities, trichloroacetic acid (TCA) application along with needling after sufficient penetration causes coagulation of proteins of the infected cells of skin and causes necrosis. Aim: To study the efficacy of 100%TCA needling in the treatment of palmoplantar warts. Study Design: Longitudinal study carried out at a tertiary care center in Gujarat. Materials and Methods: Patients having palmoplantar warts between the age group of 4-50 years over a period of 8 months were included in the study as per our inclusion and exclusion criteria. 100% TCA application followed by needling using an insulin syringe was done once per week after informed consent. The necrosed skin was pared on each follow-up and the procedure was repeated till complete clearance of warts. Results: The total number of patients were 60 out of which 6 patients were irregular in follow up. In 4 patients, the treatment modality was changed after 6 weeks because of lack or response. 50 patients had complete clearance of warts. The minimum and maximum duration for complete clearance of warts were 3 weeks and 8 weeks respectively. Limitation: It gives varying results in different individuals and average duration in clearance of wart is comparatively slower as compared to some other methods. Conclusion: TCA needling is an effective treatment modality for palmoplantar warts.

ObjectiveVaccine-preventable human papillomavirus (HPV) infection is common, especially in sub-Saharan Africa where HIV risk is also high. However, unlike other sexually transmitted infections (STIs), HPV's role in HIV acquisition is unclear. We evaluated this relationship using data from MTN-003, a clinical trial of HIV chemoprophylaxis among cisgender women in sub-Saharan Africa.DesignA case-control study.MethodsWe matched 138 women who acquired HIV (cases) to 412 HIV-negative controls. Cervicovaginal swabs collected within 6 months before HIV seroconversion were tested for HPV DNA. We estimated the associations between carcinogenic (high-risk) and low-risk HPV types and types targeted by HPV vaccines and HIV acquisition, using conditional logistic regression models adjusted for time-varying sexual behaviors and other STIs.ResultsMean age was 23 (±4) years. Any, high-risk and low-risk HPV was detected in 84, 74 and 66% of cases, and 65, 55 and 48% of controls. Infection with at least two HPV types was common in cases (67%) and controls (49%), as was infection with nonavalent vaccine-targeted types (60 and 42%). HIV acquisition increased with any [adjusted odds ratio (aOR) 2.5, 95% confidence interval (95% CI) 1.3-4.7], high-risk (aOR 2.6, 95% CI 1.5-4.6) and low-risk (aOR 1.8, 95% CI 1.1-2.9) HPV. Each additional type detected increased HIV risk by 20% (aOR 1.2, 95% CI 1.1-1.4). HIV acquisition was associated with HPV types targeted by the nonavalent (aOR 2.1, 95% CI 1.3-3.6) and quadrivalent vaccines (aOR 1.9, 95% CI 1.1-3.2).ConclusionHPV infection is associated with HIV acquisition in sub-Saharan African women. In addition to preventing HPV-associated cancers, increasing HPV vaccination coverage could potentially reduce HIV incidence.

BackgroundWomen living with HIV in sub-Saharan Africa are at increased risk to develop cervical cancer (CC), which is caused by persistent infection with 13 oncogenic human papilloma viruses (HR-HPVs). It is important to accurately identify and target HIV-positive women at highest risk to develop CC for early therapeutic intervention.MethodsA total of 2,134 HIV+ and HIV− women from South-West Tanzania were prospectively screened for cervical cancer and precancerous lesions. Women with cervical cancer (n=236), high- and low-grade squamous intraepithelial lesions (HSIL: n=68, LSIL: n=74), and without lesion (n=426) underwent high-resolution HPV genotyping.ResultsEighty percent of women who were diagnosed with HSIL or LSIL were living with HIV. Any lesion, young age, HIV status, and depleted CD4 T cell counts were independent risk factors for HPV infections, which were predominantly caused by HR-HPV types. While multiple HR-HPV type infections were predominant in HIV+ women with HSIL, single-type infections predominated in HIV+ CC cases (p=0.0006). HPV16, 18, and 45 accounted for 85% (68/80) and 75% (82/110) of HIV+ and HIV− CC cases, respectively. Of note, HPV35, the most frequent HPV type in HSIL-positive women living with HIV, was rarely detected as a single-type infection in HSIL and cancer cases.ConclusionHPV16, 18, and 45 should receive special attention for molecular diagnostic algorithms during CC prevention programs for HIV+ women from sub-Saharan Africa. HPV35 may have a high potential to induce HSIL in women living with HIV, but less potential to cause cervical cancer in single-type infections.

Background Sexually transmitted infections (STIs) are prevalent throughout the world and impose a significant burden on individual health and public health systems. Missed diagnosis and late treatment of STIs can lead to serious complications such as infertility and cervical cancer. Although sexually transmitted co-infections are common, most commercial assays target one or a few STIs. The HPV-STI ChapterDx Next Generation Sequencing (NGS) assay detects and quantifies 29 HPVs and 14 other STIs in a single-tube and single-step PCR reaction and can be applied to tens to thousands of samples in a single sequencing run. Methods A cohort of 274 samples, previously analyzed by conventional cytology/histology and Roche cobas HPV Test, were analyzed by ChapterDx HPV-STI NGS assay for detection of 43 HPV and STI. A set of 43 synthetic control DNA fragments for 43 HPV and STI were developed to evaluate the limit of detection, specificity, and sensitivity of ChapterDx HPV-STI NGS assay. Results The assay was evaluated in this study, and the limit of detection was 100% at 50 copies for all targets, and 100%, 96%, 88% at 20 copies for 34, 8, and 1 target, respectively. The performance of this assay has been compared to Roche cobas HPV test, showing an overall agreement of 97.5% for hr-HPV, and 98.5% for both, HPV16 and HPV18. The assay also detected all HPV-infected CIN2/3 with 100% agreement with Roche cobas HPV results. Moreover, several co-infections with non-HPV STIs, such as C. trachomatis, T. vaginalis, M. genitalium, and HSV2 were identified. Conclusions The ChapterDx HPV-STI NGS assay is a user-friendly, easy to automate and cost-efficient assay, which provides accurate and comprehensive results for a wide spectrum of HPVs and STIs.

Giant condyloma acuminatum (GCA) which is also called Buschke-Lowenstein tumor. It is a rare tumor of the anorectal area and external genitalia associated with low-risk HPV types 6 or 11. GCA has a high-rate of recurrence (66%) and malignant transformation (56%). The clinical features of GCA are progression of exophytic, ulcerative, and cauliflower-shaped tumors, it has significant dimensions and may undergo malignant transformation such as squamous cell carcinoma or cervical cancer. It is difficult to treat GCA, and it may be impossible for GCA to self-healing, but we herein report a rare case of a 19-year-old female with self-healing GCA.

Human papillomaviruses (HPVs), which are small, double-stranded, circular DNA viruses infecting human epithelial cells, are associated with various benign and malignant lesions of mucosa and skin. Intensive research on the oncogenic potential of HPVs started in the 1970s and spread across Europe, including Croatia, and worldwide. Nowadays, the causative role of a subset of oncogenic or high-risk (HR) HPV types, led by HPV-16 and HPV-18, of different anogenital and head and neck cancers is well accepted. Two major viral oncoproteins, E6 and E7, are directly involved in the development of HPV-related malignancies by targeting synergistically various cellular pathways involved in the regulation of cell cycle control, apoptosis, and cell polarity control networks as well as host immune response. This review is aimed at describing the key elements in HPV-related carcinogenesis and the advances in cancer prevention with reference to past and on-going research in Croatia.

Introduction/Background* The distribution of human papillomavirus (HPV) varies geographically, and each country is making its own screening and vaccination program. This study questioned the need for colposcopy for HPV types other than HPV 16 and 18, and the need for cytology incorporated into HPV testing. Methodology 1043 consecutive patients referred from August 2017 to November 2019 for colposcopy are included in the study. For statistical analysis, logistic regression analysis, ANOVA and Pearson’s correlation was used. The value of p Result(s)* HPV 16 was the most common HPV type referred, followed by HPV 18, 52, 51 and 31, respectively. HPV 16 tends to be positive in younger patients than other HPV types (p Conclusion* HPV 33 may be implemented in high-risk HPV screening protocols for direct colposcopy referral among HPV 16 and HPV 18 in specific regions. If we had been opted HPV-based screening for only HPV 16 and 18 without cytology, 19% of all CIN 2+ lesions would have been missed. HPV based screening only with HPV 16 and 18 does not seem to be feasible. Nonavalent vaccines may be considered for vaccination for this specific sub-population.

Background: This paper aimed to assess the prevalence of human papillomavirus (HPV) infection and the associations of sociodemographic and behavioral characteristics with HPV in unvaccinated men in Henan Province before the mass administration of the HPV vaccine through a baseline survey.Methods: Between June 2015 to June 2020, 3,690 men were tested for the HPV genotype at the Henan Provincial People's Hospital. The HPV genotype was detected by a polymerase chain reaction (PCR)-based hybridization gene chip assay.Results: The overall HPV infection rate was 29.97%; The most prevalent genotypes were HPV 6 (21.76%), 11 (12.68%), 16 (8.94%), 58 (5.37%), 18 (3.41%), 84 (3.25%), 61 (3.09%), and 81 (3.09%). Low-risk HPV (LR-HPV) infection (24.91%) and single infection (17.78%) were the most prevalent forms. Age-specific HPV distribution was presented as a bimodal curve; the youngest age group (≤ 25 years) had the highest HPV infection rate (36.03%), followed by the 36–40-year-old group (33.68%). Men with Junior high school or above were more likely to have Pure-LR HPV infection. Unmarried status and smoking increased single and LR-HPV infection. Multiple lifetime sex partners and not using a condom were more likely to cause LR-HPV infection.Conclusions: The data on the prevalence and HPV infection type distribution in men in Henan Province could serve as a valuable reference to guide nationwide screening. We provide a time-based estimate of the maximum impact of the HPV vaccine and critical reference measurements important for assessing the clinical benefits of HPV vaccination and the increase in non-vaccine HPV types.

Background: Human Papillomavirus (HPV) genotype distribution varies according to the method of assessment and population groups. This study analyzed type-specific HPV infections among women ranging from 14-95 years old, displaying normal and abnormal cytology, from São Paulo and Barretos cities, Brazil. Methods: Women found positive for High Risk-HPVs DNA by either the Hybrid Capture 2 (HC2) or Cobas HPV Test (n = 431) plus a random sample of 223 negative by both assays and 11 samples with indeterminate results, totalizing 665 samples, were submitted to HPV detection by the PapilloCheck test. Cytological distribution included 499 women with a cytological result of Negative for Intraepithelial Lesion or Malignancy and 166 with some abnormality as follows: 54 Atypical Squamous Cells of Undetermined Significance; 66 Low-Grade Squamous Intraepithelial Lesion; 43 High-Grade Squamous Intraepithelial Lesion and 3 (0.5 %) Invasive Cervical Cancer. Results: From the 323 samples (48.6 %) that had detectable HPV-DNA by the PapilloCheck assay, 31 were HPV negative by the cobas HPV and HC2 assays. Out of these 31 samples, 14 were associated with HR-HPVs types while the remaining 17 harbored exclusively low-risk HPVs. In contrast, 49 samples positive by cobas HPV and HC 2 methods tested negative by the PapilloCheck assay (19.8 %). Overall, the most frequent HR-HPV type was HPV 16 (23.2 %), followed by 56 (21.0 %), 52 (8.7 %) and 31 (7.7 %) and the most frequent LR-HPV type was HPV 42 (12.1 %) followed by 6 (6.2 %). Among the HR-HPV types, HPV 56 and 16 were the most frequent types in NILM, found in 19. 1 and 17.7 % of the patients respectively while in HSIL and ICC cases, HPV 16 was the predominant type, detected in 37.2 and 66.7 % of these samples. Conclusions: In the population studied, HPV 16 and 56 were the most frequently detected HR-HPV types. HPV 56 was found mainly in LSIL and NILM suggesting a low oncogenic potential. HPV 16 continues to be the most prevalent type in high-grade lesions whereas HPV 18 was found in a low frequency both in NILM and abnormal smears. Surveillance of HPV infections by molecular methods is an important tool for the development and improvement of prevention strategies. [ABSTRACT FROM AUTHOR]

Background Inverted papilloma (IP) is an uncommon disease which arises in the mucosal membrane of the nasal cavity and paranasal sinus. It has been proposed that human papillomavirus (HPV) is the causal agent in the pathogenesis of IP and plays a key role in the progression from benign IP to malignancy. As there are no prior studies that focus on an Iranian population, this study intended to characterize the prevalence of HPV types in benign and malignant forms of IP. Methods In this retrospective study, we included a total of 40 IP patients [37 benign IP and 3 IP/squamous cell carcinoma (SCC)] who were referred to Amiralam Hospital in Tehran from 2004–2006. Results HPV was detected in 18.9% and 100% of IP and IP/SCC cases, respectively. In all HPV positive cases of IP and IP/SCC cases, HPV6/11 and HPV16/18 were detected, respectively. Therefore, HPV types were different between the IP and IP/SCC patients, and this difference was statistically significant ( p = 0.002). Conclusion This study suggests that HPV6 and 11 may be involved in the development of IP, but HPV16 and 18 likely play an important role in the progression from benign to malignant form of IP.

PurposeGenital warts are one of the most common sexually transmitted infections and are known to develop due to human papillomavirus (HPV) infection, especially HPV types 6 and 11. However, their prevalence and subtypes in male genital warts remains poorly defined. HPV vaccine is administered to men in part to prevent anogenital warts and it is important to investigate their expected impact in male anogenital warts.Materials and MethodsWe have herein conducted a multicenter, prospective study to analyze HPV type distribution in genital warts of 1000 Korean men by using DNA microarray that can detect 40 types of genital HPV.Results1000 out of 1015 genital warts showed HPV DNA. Out of 1000 HPV-positive samples, 18.8% showed mixed infection and 81.2% showed single infection. Of 18 high-risk (16.2%) and 14 low-risk (94.3%) HPV types detected, the most common type of HPV types were HPV6 (59.5%), followed by HPV11 (24.3%), HPV16 (5.8%), HPV91 (5.3%), HPV40 (3.3%). 85.9% showed the 9 HPV types covered by the vaccine. Sixteen of the 200 HPV specimens submitted for sequencing showed discrepant results compared to the DNA sequencing.ConclusionsMale genital warts predominantly show low-risk type HPV (HPV 6 and 11). However, high-risk HPV is not uncommon and the role of high-risk HPV in genital warts may be considered. The Gardasil 9 HPV vaccine is expected to provide protection against about >80% of male genital warts. Further HPV typing studies in male genital warts are necessary in other races and geographical areas to define the role and management of high-risk type HPV in male genital warts.

Simple Summary This study focused on the prevalence of high-risk human papilloma virus (HR-HPV) infection types, other than HPV-16 and -18, in women throughout Kazakhstan due to the high rates of cervical cancer in Kazakhstani women. Approximately one quarter of the of the participants were infected with HR-HPV types other than HPV-16 and -18; 72% of these women were infected with one HR-HPV type with HPV-31 being the most prevalent, and the remaining 28% of these infected women were infected with multiple HR-HPVs with HPV-68 being the most prevalent type in these women. Introducing HR-HPV testing for all 14 cancerogenic types into cervical cancer screening program could help to reduce the rates of cervical cancer in Kazakhstan. Abstract Cervical cancer represents a great burden to public health of women. This study aimed to obtain a nationwide genotyping survey and analysis of high risk-HPV including those that are caused by HPV types other than HPV-16 and HPV-18, among women in Kazakhstan. This study was conducted based on the collection of survey and cervical swabs of 1645 women across the country. The samples were genotyped for high-risk HPV types based on real-time PCR methods. Collected data was analyzed with the focus on high-risk HPV types other than HPV-16 and -18. Infection was present in 22% of women who participated in the study. The most prevalent types were HPV-31 among single infections and HPV-68 among multiple infections. Conclusively, despite the lack of attention high-risk HPV types beyond HPV-16 and -18 get in attempts of cervical cancer prevention in Kazakhstan, their prevalence is high and plays a large role in cervical cancer epidemiological situation.

Aminolevulinic acid photodynamic therapy (ALA-PDT) has been widely used in the treatment of condyloma acuminatum (CA), but there is a lack of reports on clinical factors related to CA relapse after photodynamic therapy.The clinical data of patients with CA treated with ALA-PDT from April 2018 to December 2019 were retrospectively analyzed, including HPV type, follow-up time and recurrence within 6 months after treatment. The patients were classified into single-type HPV infection and multiple-type HPV infection groups. Besides, the patients were also classified into high-risk HPV infection, low-risk HPV infection, and low + high-risk HPV infection groups. Univariate and multivariate COX regression was performed to analyze whether HPV type was related with CA relapse after photodynamic therapy.A total of 161 CA patients who underwent ALA-PDT were analyzed in this study. CA recurred in 20 patients within 6 months after treatment, with a recurrence rate of 12.4%. Of them, the patients with multiple-type HPV infection made up 85%. Multivariate COX regression analysis revealed that multiple-type HPV infection was associated with CA recurrence (HR:5.0; 95% CI: 1.1-21.4; P = 0.032). Of the patients with CA recurrence, 70% developed low + high-risk infections, a proportion significantly higher than that in patients without CA relapse (16.3%, P0.001). Using low-risk infection as a reference, low + high-risk infection was positively correlated with postoperative recurrence (HR: 6.7; 95% CI: 1.6-26.2; P = 0.006).Multiple-type HPV infection were closely associated with CA recurrence after photodynamic therapy.

Appalachian women 18 to 26 years old have high baseline seropositivity rates for at least 1 of the 4 human papillomavirus vaccine–related types, but low vaccine-relevant type infections. Supplemental digital content is available in the text., Background Key informants of the Appalachian community questioned whether their unique environmental stressors would alter their immune response to human papillomavirus (HPV) infections. The primary aim of this study is to determine predictors of HPV seroprevalence to at least 1 of the 4 vaccine-related HPV types before vaccination using a psychoneuroimmunologic model in Appalachian women. Method Women aged 18 to 26 years (n = 185) who had not received HPV vaccination provided cervical HPV DNA and blood samples. Human papillomavirus DNA was identified through Hybrid Capture 2 assay and then genotyped for HPV types 6, 11, 16, and 18 by Roche Linear Array. Competitive Luminex Immunoassay measured the type-specific antibodies to HPV types 6, 11, 16, and 18 in milli-Merck units per milliliter. Nine psychoneuroimmunology scales measuring attributes of stress were self-completed. Results Human papillomavirus DNA was detected in 50% (92/183) of participants, with only 14% (26/183) positive for HPV-6/11/16/18 DNA. Seropositivity for at least one anti–HPV-6/11/16 or 18, on the other hand, was present in 35% (64/183) of women, with only 10% (19/183) concomitantly infected and seropositive for the vaccine-related types. The Perceived Stress Scale was not a strong predictor of HPV seropositivity. Conclusions Both HPV infection and vaccine-related HPV type seropositivity is common among Appalachian women aged 18 to 26 years. The anticipated effect of environmental stressors on HPV seropositivity was not seen when multiple predictors were considered.

Objectives: Human papillomavirus infection is one of the most common sexually transmitted infections. Long-term exposure to the HPV leads to high-grade squamous intraepithelial lesions affecting cervical cancer. Knowledge about the distribution of HPV genotypes is crucial to guide the introduction of prophylactic vaccines. We aimed the genotype distribution in patients reporting due to abnormal Pap — smear tests. Material and methods: We provide a prospective observational cohort study. We obtained material from 428 women registered to Provincial Hospital in Poznan and Specialist Medical Practice in 2018–2020. In the current study, we analyze results from the first 110 inclusions with the diagnosis of HSIL from a cervical biopsy. The probe for the molecular test was collected with a combi brush and passed to an independent, standardized laboratory. HPV detection was done using PCR followed by DNA enzyme immunoassay and genotyping with a reverse hybridization line probe assay. Sequence analysis was performed to characterize HPV-positive samples with unknown HPV genotypes. The molecular test detected DNA of 41 HPV genotypes. We performed statistical analyzes using the STATISTICA package 13.3. Results: We found that 98.2% of patients received HPV-positive test results. The most frequent HPV genotype was 16, which assumed for 54.1%. In patients negative for HPV 16, the percentage decreased with increasing age. We detected that the following HPV types are next most common: HPV 31 (16.2 %), HPV 52 (11.7%), HPV 51 (9.9%), HPV 18 (9.0%), HPV 33 (9%). Moreover, thyroid diseases were the most common comorbidities and occurred in 15 patients Conclusions: To our knowledge, this study is the most extensive assessment of HPV genotypes in HSIL diagnoses in Poland.

BackgroundCervical cancer is the second most common cancer among women in Ethiopia, India, Nigeria, and Pakistan. However, of these four countries, only Ethiopia has introduced human papillomavirus (HPV) vaccination at the national level in 2018 and India in a few states in 2016. Our study objective was to estimate the potential health impact of HPV vaccination among ten cohorts of 9-year-old girls from 2021–2030 in Ethiopia, India, Nigeria, and Pakistan using two independent mathematical models, and assess similarities and differences in vaccine impact projections through comparative modelling analysis.MethodsUsing two widely published models (Harvard and PRIME) to estimate HPV vaccination impact, we simulated a vaccination scenario of 90% annual coverage among 9-year-old girls from 2021–2030 in Ethiopia, India, Nigeria, and Pakistan. We estimated the potential health impact in terms of cervical cancer cases, deaths, and disability-adjusted life years (DALYs) averted among vaccinated cohorts from the time of vaccination until 2100. We also conducted a comparative modelling analysis to understand the differences in vaccine impact estimates generated by the two models.ResultsPrior to harmonising model assumptions, the range between the PRIME model and the Harvard model for the potential health impact of HPV vaccination in terms of the number of cervical cancer cases averted among girls vaccinated 2021–2030 between the year of vaccination and 2100 was: 262,000 to 270,000 in Ethiopia; 1,640,000 to 1,970,000 in India; 330,000 to 336,000 in Nigeria; and 111,000 to 133,000 in Pakistan. When harmonising model assumptions, alignment on HPV type distribution significantly narrowed the differences in vaccine impact estimates.ConclusionsThe main difference in estimates for cases, deaths, and DALYs averted by vaccination between the models are due to variation in interpretation around data on cervical cancer attribution to HPV-16/18; differences in estimates for DALYs averted are additionally due to differences in age-specific remaining life expectancy over time between the two models. As countries make progress towards the World Health Organization targets for cervical cancer elimination, continued explorations of underlying differences in model inputs, assumptions, and results when examining cervical cancer prevention policy will be critical.

This study evaluated the presence of HPV DNA in the cervix and peripheral blood of women with cervical intraepithelial neoplasia (CIN I, II, and III) and healthy individuals. Overall, 139 paired peripheral blood and cervix samples of healthy women and women with CIN I, II, and III (n= 68) were tested for HPV DNA by using standard procedures. PCR-sequencing determined HPV types. Quantification of HPV16 E6 and E2 genes was performed to determine viral load and physical state. HPV DNA was detected in the cervix (21.1% in healthy individuals; 48.8-55.5% in CIN patients), blood (46.4% in healthy individuals; 44.1-77.7% in CIN patients), and paired peripheral blood and cervix samples (24% in healthy individuals; 32.5-44.4% in CIN patients). The most frequent types found in the cervix were HPV16, 18, 31, 33, 58, and 70, while HPV16, 18, 33, 58, and 66 were the most frequent types found in the blood. HPV DNA in the cervix was associated with previous sexually transmitted infections (STIs) (P=0.023; OR: 2.978; CI:1.34-7.821), HPV DNA in the blood (P=0.000; OR: 3.369; CI:3.700-18.540), and cervical lesions (CIN I/II or III) (P=0.001; OR: 3.369; CI:1.634-6.945). Binomial Logistic regression showed that HPV DNA in the blood (P=0.000; OR: 9.324; CI:3.612-24.072) and cervical lesions (P=0.011; OR: 3.622; CI:1.338-9.806) were associated with HPV DNA in the cervix. However, we did not find an association between HPV DNA in blood and cervical lesions (P=0.385). Our results showed that, although there is an association between HPV DNA in the cervix with HPV DNA in blood, only HPV DNA found in the cervix was associated with cervical lesions.

An Escherichia. coli-produced HPV-16/18 bivalent vaccine has been proved to be well-tolerated and highly efficacious against diseases associated with vaccine HPV types. As a part of the multi-center, randomized, double-blind phase III clinical trial, this lot-to-lot consistency study aimed to assess the safety and immunogenicity consistency of this novel HPV vaccine, which is also one of the objectives of the phase III trial. A total of 3689 healthy women aged 18–45 years were enrolled and randomly assigned 1:1:1 to three lots of the HPV vaccine groups. The primary outcomes were the IgG antibody level at 1 month after the last dose (month 7). In the immunogenicity per-protocol set (PPS), almost all of the participants seroconverted at month 7 and remained seropositive at month 42. For each paired comparison of the three lot groups, the two-sides of 90% CIs of GMC ratios for both IgG and neutralizing antibodies for HPV-16 and HPV-18 at month 7 were within the equivalence interval [0.5, 2]. Lot consistency was also demonstrated at month 42. The majority of recorded solicited reactions were mild or moderate. The incidences of solicited reactions of Lot 2 and Lot 3 were slightly higher than Lot 1. However, the incidences of solicited reactions of ≥ grade 3 and solicited reactions by symptoms were all similar among the three lot groups. None of the SAEs was considered related to vaccination by the investigator. In conclusion, this study demonstrates lot-to-lot consistency of the 3 consecutive lots of the E. coli-produced HPV-16/18 bivalent vaccine.

With the recent introduction of the renewed National Cervical Screening Program (NCSP) in Australia, utilising primary human papillomavirus (HPV) nucleic acid testing (NAT) for known oncogenic HPV types rather than cervical cytology, we reflect on three asymptomatic women with negative oncogenic HPV test results and high-grade cervical abnormalities including cervical intraepithelial neoplasia (CIN) III and cervical squamous cell carcinoma (SCC). The two cases with CIN III had a 'probable' oncogenic subtype (HPV 53) identified on further testing, while the case of SCC had no HPV virus identified. These cases serve as a reminder of the need for ongoing diligence despite low-risk screening under the new program.

Early diagnosis and genotyping of high-risk human papillomavirus (HR-HPV) in cervical tissue specimens is significant for cervical cancer prevention. A sensitive microplate fluorometric hybridization assay (MFHA) was designed for the detection of HPV DNA 16 and 18 in cervical tissue. Following optimization and validation of the method, 60 formalin-fixed and paraffin-embedded cervical samples representing different cervical intraepithelial neoplasia grades of HPV-associated lesions were tested to determine the sensitivity and specificity of the assay. Using consensus GP5+/6+ biotin–labeled primers to amplify a conserved region within the L1 gene, the amplicons were added to the microplate wells coated with specific probes for the hybridization of HPV 16 and 18 individually. Final detection was performed with streptavidin-AlexaFluor488 conjugated. The results were then compared with type-specific nested polymerase chain reaction (PCR) and colorimetric microplate assay. While the agreement between the results obtained by the type-specific nested PCR and fluorometric assay for the detection of both HR-HPV types was 100%, this agreement for the detection of HPV type 16 and 18 using microplate colorimetric assay was 94.2% and 85% respectively. Overall, the results of the fluorometric and colorimetric assays are promising for detecting both HR-HPV types in a large number of cervical tissue samples with the higher MFHA assay sensitivity.

Background Human papillomavirus (HPV) is one of the most common sexually transmitted viruses. Data about HPV infection in Guizhou is limited. Methods 56,768 cervical samples were collected and genotyped for 15 main high risk and 6 main low risk HPV types. Results 16.95% (9623/56768) of samples were HPV positive; 90.70% (8728/9623) of HPV positive women were infected by high risk HPV. High risk and high risk mix infection (1458; 70.85%) was the most common mix HPV infection type. The highest HPV detection rate was found in age group 41–45 years old (detection rate = 17.89%) (χ2 = 204.77; P P P Conclusions Characteristics of HPV distribution in Guizhou were identified. There were significant differences in HPV distribution among age groups, prevention strategies should be adjusted according to the characteristics.

PurposeHigh rate of false-positive tests is a major obstacle to use human papillomavirus (HPV) detection as a diagnostic tool for high-grade squamous intraepithelial lesions or cervical cancer (HSIL+). We investigated whether type-specific viral load or physical state of HPV 16, 18, and 58 are useful biomarkers for HSIL+.Materials and MethodsType-specific viral loads of E6 and E2 genes in cervical cells from 240, 83, and 79 HPV 16–, 18–, and 58–infected women, respectively, were determined using real-time polymerase chain reaction. Viral loads were normalized to cellular DNA (copy/cell). Total and integrated viral loads and physical state were compared between HSIL+ and controls, and diagnostic value was determined using receiver operating characteristic analysis.ResultsViral loads of HPV 16, 18, and 58 were significantly different in lesions in the same pathologic grade. High type-specific total viral loads were significantly associated with HSIL+ (odds ratio [OR], 14.065, 39.472, and 7.103 for HPV 16, 18, and 58, respectively). High integrated viral load was related to HSIL+ in women with HPV 16 (OR, 8.242), and integrated state was associated with HSIL+ in women with HPV 18 (OR, 9.443). Type-specific total viral load was significantly associated with HSIL+ (area under curve, 0.914, 0.937, and 0.971 for HPV 16, 18, and 58, respectively), indicating an excellent performance in detecting HSIL+.ConclusionType-specific total viral load may be a powerful diagnostic marker for HSIL+ in HPV 16–, 18–, and 58–infected HSIL+ lesions. If demonstrated in all other high-risk HPV types, this method can lead to a paradigm shift in the strategy of equivocal cytologic abnormalities.

Objective To identify practice patterns regarding human papillomavirus (HPV) vaccination efforts and vaccination rates in context of head and neck cancer prevention, identify barriers to vaccination, and identify gaps in knowledge regarding the link between HPV and head and neck cancer in the pediatrician population. Study design/Methods A 27-question cross-sectional survey was distributed to members of the four California chapters of the American Academy of Pediatrics. Results Of the completed responses, 89.4% identified as “always” recommending the HPV vaccine to patients, but only 19.5% of pediatricians estimated that >75% of their eligible patients had completed the HPV vaccination series. 71.5% of respondents felt that further education about HPV's link to head and neck cancer them more comfortable discussing vaccination. Physicians who were in practice longer were less likely to respond that additional education about HPV and its link to head and neck cancer would make them more comfortable discussing vaccination with patients (p = 0.043). Physicians who were in practice longer were more likely to correctly respond that HPV type 16 is the most common strain linked to head and neck cancer (p = 0.021). Conclusion There is need to improve both the knowledge base and comfort level of pediatricians in counseling their patients during vaccine recommendations. Otolaryngologists have a critical role in providing education to physicians, trainees, and the general public in the effort to combat the epidemic of HPV-associated head and neck cancer.

This review is devoted to assessing the prevalence of human papillomavirus (HPV) in head and neck tumors (HNC). HPV is recognized as the etiological factor of cervical cancer, but it may be involved in other tumors progression. Of the 28 studies presented, 6 studies showed a low incidence of HPV in HNC tissue (1.6—6.2 %). Most often, HPV was detected in Singapore (90.6 %), Japan (100 %) and France (94.7 %). Most often found 16 types of virus (82 %) and 18 types (43 %). Low-grade HPV type 11 was most often observed in the Russian Federation (19 %). The frequency of occurrence of HPV in HNC varies, which raises the question about impact HPV and co-infection in HNC progression. It makes further research in this area relevant and promising.

Background The aim of this paper was to conduct a baseline survey of HPV infection in unvaccinated women in Xinjiang Uyghur Autonomous Region before the mass use of HPV vaccine. Methods Between 2008 and 2018, the HPV genotype detected by a PCR-based hybridization gene chip assay of 37,722 women who were from Gynecology Department and Health Management Center of the First Affiliated Hospital of Xinjiang Medical University were tested HPV genotype by a PCR-based hybridization gene chip assay. All statistical analysis methods were performed with this statistical software including Python version 3.6.1, R Software 3.5.1 and Excel 2011. Results The total positive rate for HPV was 14.02%, the most prevalent genotypes were HPV 16 (3.79%), HPV 52 (2.47%), HPV 58 (1.76%), HPV 53 (1.35%) and HPV 31 (0.72%). The single infection (11.34%) and high-risk HPV (HR-HPV) infection (9.72%) was the main prevalence of HPV. Age-specific HPV distribution was presented as a bimodal curve, while the youngest age group (≤25 years) presented the highest HPV infection rate (20.78%), which was followed by a second peak for the 36–40 age group. According to the ethnic stratification, the HPV infection prevalence ranging from the high to low was: Mongol (16.36%), Hui (15.15%), Kazak (14.47%), Han (14.43%), Other (14.37%), Uygher (10.96%). From 2009 to 2013, the HPV infection rate fluctuated but did not changed much. It peaked in 2014 and then fell significantly, reached the bottom point in 2017 and rose slightly in 2018. In 2015, the infection rate of HPVl6 and 52 in the population was almost the same (both 3.40%) the infection rate of HPV52 type (3.31%) was higher than that of HPVl6 type (2.18%) and became the dominant type in 2016. Conclusions We present data regarding the prevalence and type distribution of HPV infection, which could serve as the valuable reference to guide nationwide cervical cancer screening. These baseline data enable the estimates of maximum HPV vaccine impact across time and provide critical reference measurements which are important to the assess of clinical benefits and potential harms in HPV vaccination and the increase in non-vaccine HPV types.

International audience; Vaginal self-sampling and human papillomavirus (HPV) DNA testing can be useful tools for women with limited access to health care living in sub-Saharan Africa. To assess the feasibility and acceptability of vaginal self-sampling and high-risk HPV prevalence in two villages of central Senegal, women were asked to self-sample vaginal swabs for HPV detection in May, 2016. Vaginal swabs were collected from 133 women and were tested for HPV genotyping. The acceptability rate of vaginal self-sampling was 98.5%, and 99.2% of the women (133/134) used the device correctly. The quality of self-sampling was satisfactory in 100% of the samples; 10.5% of the samples were positive for HPV, including 6% with high-risk HPV types and 4% with low-risk HPV types. This preliminary study indicates that vaginal self-sampling is a valuable strategy for high-risk HPV detection and cervical cancer screening in a population of women not attending gynecologic screening in rural areas of Senegal.

Background: Human Papillomavirus (HPV) vaccination of girls was introduced in Germany in 2007. However, data on the distribution of vaccine-relevant HPV types in the general population in Germany in the prevaccine era are limited. Methods: Serum samples collected during the German National Health Interview and Examination Survey 1998 (GNHIES98), a nationally representative study including men and women aged 18–79 years, were tested for antibodies to 19 mucosal and cutaneous HPV types. Multivariable regression models were developed to identify associations between demographic and behavioral characteristics and HPV seropositivity. Results: Of the 6517 serum samples tested, almost a quarter was seropositive for at least one of the nine HPV vaccine types with no clear age-pattern. HPV-6 and HPV-59 were the most common mucosal types, while HPV-1 and HPV-4 were the most common cutaneous HPV types. Factors independently associated with HPV-16 seroprevalence were seropositive to other sexually transmitted infections and lifetime number of sex partners, as well as urbanity (only among females). Conclusions: Prevalence of naturally acquired antibodies to HPV types which can be prevented by vaccination is high in both sexes and all age groups. These data can serve as baseline estimates to evaluate the population-level impact of the current vaccination strategy.

Introduction . High prostate cancer (PC) incidence rates testify to importance of research into genesis of the given disease and means of its prevention. The item of oncogenic human papillomaviruses (HPVs) participance in PC origination is still being the subject of debates. If association of PC with HPV is proven prophylaxis of the given disease becomes possible by means of inoculating boys with the vaccines made for cervical cancer (CC) prevention.Objective: to test whether prostate tissues surgically removed from PC patients harbor oncogen E7 of HPV18 – the second most common HPV type responsible for CC.Materials and methods . The study was carried out on prostate glands of 17 PC patients surgically treated in N.N. Blokhin National Medical Research Center of Oncology. Detection of HPV18 oncogen E7 was done by polymerase chain reaction. To elevate polymerase chain reaction sensitivity DNA was isolated from homogeneous cell populations collected by means of microdissections from cryopreserved PC specimens.Results . Amplification products corresponding to HPV18 oncogen E7 were registered in tests from 2 PC patients.Conclusion . HPV18 oncogen E7 was detected in surgically removed prostate tissues of 2 PC patients. In the aggregate with our previous result (7 HPV16-positive PC cases in the same group of 17 patients) the given result enables one to presume participance of oncogenic HPVs in PC genesis. The problem deserves further study.
