Abstract Background Data about the genotype-specific human papillomavirus (HPV) prevalence in the Czech Republic is limited. We aimed to evaluate the prevalence and concordance of genotype-specific HPV infection detected in semen samples, penile swabs and cervical swabs from non-vaccinated heterosexual couples without HPV-associated disease. Methods Semen samples and penile swabs were collected from male partners and cervical swabs were collected from female partners of heterosexual couples treated for infertility (n = 195). Presence of HPV DNA in semen samples and cervical swabs was analyzed using the cobas® HPV Test and PapilloCheck®. Only the PapilloCheck® test was used to detect HPV in penile swabs. The genotype-specific prevalence and concordance of HPV infection not targeted by vaccine were evaluated using Fisher exact test. Results Both partners were infected with any HPV type in 13.8% (27/195) of couples and, of these couples, 55.6% (15/27) harbored at least one mutual genotype. High-risk HPV (hrHPV) genotypes were detected in 12.3% (24/195) of semen samples, 31.3% (61/195) of penile swabs, and 19.5% (38/195) of cervical swabs (P < 0.001). The most prevalent hrHPV genotype were HPV53 (2.56%; 5/195) in semen samples, HPV16 (6.67%, 13/195) in penile swabs and HPV39 (3.59%, 7/195) in cervical swabs. Low-risk (lrHPV) genotypes were detected in 5.13% (10/195) of semen samples, 15.9% (31/195) of penile swabs, and 4.10% (8/195) of cervical swabs (P < 0.001). Male sexual partners of HPV-positive women were more likely to be infected with at least one of the same HPV types than female sexual partners of HPV-positive men (34.9% vs. 17.9%, P = 0.055). Conclusions This study showed that the detection of HPV infection differ by anatomic site and gender. Regardless the anatomic site, high prevalence of HPV genital infection was found in both Czech men and women.

AbstractMen who have sex with men (MSM) are disproportionately affected by anal cancer, predominantly caused by high-risk (HR) human papillomavirus (HPV) infection. Currently, the nonavalent HPV vaccine provides coverage against nine HPV genotypes, including seven HR-HPV genotypes. Here, we characterize anal HR-HPV genotype distribution and associated risk factors in MSM from Toronto, Canada recruited between September 2010 and June 2012. Wilcoxon–Mann–Whitney test was used for continuous variables, Chi-square test was performed for categorical variables, and a multivariable model using logistic regression was created to assess for correlates of anal HR-HPV infection. A total of 442 MSM were recruited, with a median age of 45 (IQR 38–50) and an overall HPV prevalence of 82%. The prevalence of any HR-HPV infection was 65.3% and 50.7% in the HIV-positive and HIV-negative MSM, respectively. No participant tested positive for all genotypes covered by the nonavalent vaccine. HIV status (aOR 1.806; 95% CI 1.159–2.816), smoking (aOR 2.176; 95% CI 1.285–3.685) and the number of lifetime sexual partners (aOR 2.466; 95% CI 1.092–5.567) were independent risk factors for anal HR-HPV infection. Our findings will be useful to inform HPV vaccine rollout and HPV prevention strategies in Canadian MSM.

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.

Abstract Background: Homosexual men or men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviors. In this large study, a meta-analytic approach was used to systematically analyze the literature to elucidate the prevalence and genotype distribution of anal, penile, oral, and urethral HPV infection among MSM in the world.Methods: To carry out this systematic review, five electronic databases were searched for relevant studies published from January 2012 through to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalences were calculated for each anatomical region using random-effect model weighted by the inverse variance method. Subgroup analyses were performed to identify the probable sources of heterogeneity. The meta-analysis was performed using the “Metaprop” function in the R package Meta.Results: The overall pooled prevalence of anal, penile, oral, and urethral HPV infection among MSM were 78.11 % (95% CI: 75.50%-80.52%), 36.26% (95% CI: 29.13%–44.05%), 17.33% (95% CI: 13.65%–21.75%), and 15.40% (95% CI: 7.86%–27.97%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis, and oral cavity was HPV-16 (20.32%, 4.96%, and 3.16%, respectively). Conclusion: HPV infection is on the dramatic rise in MSM because of high-risk sexual behaviors, strongly suggesting the increased risk of developing HPV-related diseases and malignancies in this population. Among different sexual orientations, male homosexuality is associated with the highest risk of acquiring sexually transmitted infections.

Abstract Background: The epidemiology on the human papillomavirus (HPV) among females in Southern China is not well-established. Baseline data on the prevalence of HPV infection in China prior to mass prophylactic HPV vaccination would be useful. Thus, this study aimed to determine the type-specific HPV prevalence and distribution among females from Southern China prior to mass HPV vaccination. Methods: A retrospective cross-sectional study employing 214,715 women attending ChenZhou NO.1 People’s Hospital for cervical screening during 2012-2018 was conducted prior to widespread HPV vaccination. HPV genotype was detected using nucleic acid molecular diversion hybridization tests. The overall prevalence, age-specific prevalence, type distribution, and annual trend were analyzed. Results: The overall HPV prevalence was 18.71% (95% confidence interval [CI], 18.55%-18.88%) among Southern China females. During 2012–2018, the prevalence of HPV infection showed a downward tendency, from 21.63% (95% CI, 21.07%-22.20%) in 2012 to 18.75% (95% CI, 18.35%-19.16%) in 2018. Age-specific HPV distribution displayed a peak at young women aged less than 21 years (33.11%, 95% CI, 31.13%-35.15%), 20.07% (95% CI, 19.70%-20.44%) among women aged 21-30 years, 17.29% (95% CI, 17.01%-17.57%) among women aged 31-40 years, 17.23% (95% CI, 16.95%-17.51%) among women aged 41-50 years, 21.65% (95% CI, 21.11%-22.20%) among women aged 51-60 years, and 25.95% (95% CI, 24.86%-27.07%) among women aged over 60 years. Of the 21 subtypes identified, the most three prevalent high-risk HPV (HR-HPV) genotypes were HPV52 (5.12%; 95% CI, 21.11%-22.20%), -16 (2.96%; 95% CI, 2.89%-3.03%), and -58 (2.51%; 95% CI, 2.44%-2.58%); the predominant low-risk HPV (LR-HPV) genotypes were HPV81 (1.86%; 95%CI, 1.80%-1.92%) and -6 (0.69%; 95% CI, 0.66%-0.73%) respectively. Incidence of HR-HPV only, LR-HPV only and mixed LR- and HR-HPV were 15.17%, 2.07% and 1.47% respectively. Besides, single HPV infection accounted for 77.30% of all positive cases in this study.Conclusions: This study highlights 1) a high prevalence of HPV infection among females with a decreasing tendency towards 2012-2018, especially for young women under the age of 21 prior to mass HPV vaccination; 2) HPV52, -16 and -58 were the predominant HPV genotypes, suggesting potential use of HPV vaccine covering these HPV genotypes in Southern China.

Abstract Background Human papillomavirus (HPV) infection is involved in cervical cancer development, and hence understanding its prevalence and genotype distribution is important. However, there are few reports on the prevalence and genotype distribution of HPV in the city of Huzhou in China. Methods In this retrospective cross-sectional study, 11,506 women who visited Huzhou Maternity & Child Health Care Hospital between January 2018 and October 2019 were enrolled. The results of HPV genotyping and cytology tests were analyzed. Results The overall prevalence of HPV infection was 15.5%. The rate of high-risk (HR) HPV infection (13.5%) was higher than that of single low-risk (LR) HPV infection (2.0%) (p&lt;0.05). The five most common HPV genotypes were HPV52 (3.3%), 16 (1.9%), 58 (1.7%), 53 (1.5%), and 81 (1.2%). The infection rate of HPV peaked in women aged 16–24 and women aged ≥55. The infection rate of HPV58 or HPV81 appeared as a single peak in women aged ≥55. The rates of HR-HPV and LR-HPV infection were higher in subjects with abnormal cytology (p&lt;0.05). Conclusions HPV infection is high in Huzhou, and HPV53 and HPV81 are the prevalent genotypes. HPV infection rate is associated with age and cytology. Regional HPV surveillance is essential to optimize current HPV prevention and vaccine development.

Aims A case-control study was performed to investigate the relationship between cervical cancer and TP53 polymorphism at codon 72 in young black African women from The Gambia. Materials and Methods The TP53 polymorphism at codon 72 was examined by PCR amplification and SSCP analysis in 40 patients with primary cervical cancer and in 20 healthy women of the same age and from the same geographical area. The occurrence of TP53 polymorphism in combination with the HPV-16 E6 genotype (assayed by PCR) was evaluated. Results The distribution of TP53 genotypes in cervical cancer patients and in the control group was not statistically different (p=0.45) and homozygosity for argine at residue 72 was not associated with cervical cancer (odds ratio: 1.24; 95% confidence interval 0.21-9.16). Similarly, a different genotype distribution, cervical cancer and presence of HPV-16 E6 were not observed. Conclusions These results cannot rule out an association between TP53 polymorphism at codon 72, HPV infection and the etiology of cervical cancer in this population sample.

SUMMARYThe prevalence and genotype distribution of human papillomavirus (HPV) infection in women with normal cervical cytology varies widely according to the population studied. Two non-overlapping population-based cohort studies of women aged ⩾30 years for the periods 2008–2009 (n=5026) and 2004–2005 (n=10 014) were analysed. The prevalence rate of HPV was 11·0% (95% CI 10·5–11·6). HPV infection was significantly associated with age, menopausal status, and inversely associated with hormone replacement therapy. There was an increasing trend of α3/α15, α5/α6, and multiple HPV infections with increasing age. The five most common types were HPV52, 18, 53, 58 and 70, while HPV16, 31, 33 ranked 21st, 25th, and 16th, respectively, in the merged cohort with normal cytology (n=14 724). HPV16, 31, and 33 were significantly associated with abnormal cytology, which could have resulted in their rarity in the total merged cohort (n=15 040).

Objectives: To estimate the frequency of human papillomavirus (HPV) infection and the genotype distribution of HPV among women with a Pap smear showing atypical squamous cells of undetermined significance (ASC-US) attending the Program for the Detection and Control of Cervical Cancer in Bogotá, Colombia. Study Design: Cervical samples from 200 women with an ASC-US Pap smear were analyzed for the presence of HPV DNA and genotype distribution using a commercial molecular technique (Linear Array®; Roche Molecular Systems, USA). Results: HPV infection was found in 140 women (70%). High-risk HPV types were present in 46.4% of the samples; 16.4% showed a low-risk HPV type, and 37.1% showed both. Of the positive samples, 42.9% were infected with a single viral genotype, whereas 57.1% exhibited multiple HPV infections. The most common HPV genotypes were HPV 16, 53, and 52 with a prevalence of 26.4, 16.4, and 13.6%, respectively. Conclusion: The epidemiological characterization of HPV infections described in this study might guide actions for epidemiological surveillance to strengthen the program in Bogotá and to develop appropriate HPV vaccination programs.

Background.Transporter associated with antigen processing (TAP) is responsible for peptide loading onto class I major histocompatibility complex (MHC-I) molecules. TAP seems to facilitate the detection of HPV by MHC-I molecules and contributes to successful eradication of HPV. TAP polymorphisms could have an important impact on the course of HPV infection.Objective.The aim of this study is to evaluate the association between five TAP gene polymorphisms and the risk of CIN.Methods.This case-control study investigated five common TAP polymorphisms in TAP1 (1341 and 2254) and TAP2 (1135, 1693, and 1993) in 616 women with CIN and 206 controls. Associations between gene polymorphisms and risk of CIN were analysed by univariate and multivariable models. The combined effect of the five TAP gene polymorphisms on the risk for CIN was investigated by haplotype analysis.Results.No significant difference in genotype distribution of the five TAP polymorphisms was observed in women with CIN and controls. Haplotype analysis revealed that women with haplotype mut-wt-wt-wt-wt (TAP polymorphisms t1135-t1341-t1693-t1993-t2254) had a significantly lower risk for CIN, compared to women with the haplotype wt-wt-wt-wt-wt (; OR 0.5 []).Conclusion.Identification of this haplotype combination could be used to identify women, less susceptible for development of CIN following HPV infection.
