The risk of high-grade lesions and carcinoma is known to correlate with specific high-risk HPV genotypes. The distribution of HPV types varies between countries and little is known about HPV distribution in our country. Therefore, the purpose of this study was to determine the range and frequency of HPV genotypes in studied group of women in Montenegro. HPV genotypes were determined using the method of enzyme restriction of PCR products amplified with group-specific primers MY09/MY11 and restricted with seven different restriction endonucleases. Out of the total number of women HPV infection was found in 1/5 of participants (20%). Genotyping performed in HPV DNA positive women shows that the HPV genotype 16 is dominant and present in more than 1/3 of the participants (36.8%). The second most frequent HPV infection is with HPV genotype 58 and it is found in 10.5% of participants. HPV 31 and HPV 6 infections are present in 7.9% of women, while infections with other genotypes were demonstrated individually by 2.6%. Multiple HPV infection was demonstrated in 18.4% and they are dominant in younger women (aged 25 to 30 years).

Background. Cardiovascular diseases are leading causes of death worldwide. Recent studies suggest that infection by some viruses, including the human papillomavirus (HPV), may increase the risk of developing atheromatous lesions on coronary arteries. However, there is a lack of data regarding the possible association between HPV infection and coronary artery disease (CAD) in women. Objective. To investigate whether HPV infection is associated with the occurrence of CAD among climacteric women. Methods. The presence of CAD and cervical HPV DNA was investigated in 52 climacteric women. Social and demographic variables and metabolic profiles were also investigated. Results. Among 27 women with CAD, 16 were positive for HPV, whereas 11 were negative. The presence of cervical HPV was strongly associated with CAD, after adjusting for demographic variables, health and sexual behaviors, comorbidities, and known cardiovascular risk factors. HPV-positive women showed a greater likelihood of having CAD (odds ratio [OR] = 3.74; 95% confidence interval [CI]: 1.16 to 11.96) as compared with HPV-negative women, particularly those infected with high-risk HPV types (OR = 4.90; 95% CI: 1.26 to 19.08). Conclusion. These results support the hypothesis that HPV infection might be associated with CAD among climacteric women, though further studies are needed to investigate the mechanisms involved.

AbstractBackground. Cervical cancer (CC) is a major public health problem worldwide. Knowledge of human papillomavirus (HPV) genotype prevalence and distribution is important for the introduction of an effective vaccination program and the corresponding epidemiological monitoring. The aim of this study was to identify and analyze the distribution of high-risk HPV genotypes.Methods. Data were collected from 136 patients for the detection of circulating HPV genotypes, where Pap test results revealed the presence of koilocytes or high risk (HR) dysplastic lesions, elements that raise the suspicion of HPV infection.Results. HPV infection was identified in 72 (55.4%) of the patients tested, 34 (47.3%) with single infection, and 38 (52.7%) with multiple infections. Twenty-two different types of HPV were identified: 14 high risk HPV types, 7 low risk HPV types, 1 probable high risk HPV type. HPV 16 was the most frequently detected (55.6%) one, it was involved in single (15 cases) and multiple (25 cases) infections, primarily associated with type 18 (12 cases), and type 52 (11 cases). The presence of HPV 18 (29.2%) and HPV 52 (23.6%) was identified after HPV type 16.Conclusions. Oncogenic HPV genotypes 16, 18, and 52 were most frequently associated in women with dysplastic lesions, which require the use of polyvalent HPV vaccines when assessing cross-protective effects of specific immunoprophylaxis programs.

Abstract Study question Is there any correlation between men infertility and HPV infection and its impairment on sperm quality? Summary answer There is a significantly higher prevalence of high-risk HPV in infertile men than fertile men. HPV infection does not impair sperm quality. What is known already Many factors may cause the infertility in males and females. Human papillomavirus are the most frequently sexually transmitted DNA viruses and etiological agents of cervical cancers. There is association between HPV infection in females and adverse pregnancy outcomes such as spontaneous abortion and spontaneous preterm delivery. Previous studies have reported the detection of HPV DNA in semen and in different sites of the male reproductive tract, such as glans penis and scrotum. Recent reports suggested that HPV may affect sperm parameters and lead to male infertility. The impact of HPV infection upon male fertility abnormality has received far less attention. Study design, size, duration In this study case control study we examined 38 fertile and 36 men from infertle couples. Participants/materials, setting, methods we examined the swabs of the entire penile surface and semen samples for HPV detection and genotyping from 38 fertile men and 36 from men from infertile couples.HPV were detected with PCR method. Sperm was also examined for its motility, sperm quantity and morphology . Main results and the role of chance Among 36 confirmed infertile males, only 8 (22.22%) cases were tested positive for HPV of semen samples and 2 among fertile men were HPV-positive (5.26%) of semen samples. Among infertile males 14 (38.88%) had HPV positive penile swabs, and only 1 (2,63%) had positive HPV swab among fertile men. The most prevalent HPV types in the male external genitalia were HPV–16. The most prevalent HPV types in semen were HPV–53. This data revealed a significant association between high-risk HPV and male infertility (P = 0.03). Sperm quality (morphology and motility) did not differ significantly between men with seminal HPV infection and uninfected men. Limitations, reasons for caution There were some limitations in the study such as differences in age. sample sizes and the number of HPV genotypes detected. Wider implications of the findings: We need larger studies and more further investigations to confirm the impact of HPV on male infertility. Trial registration number 2

Abstract Background Human papillomavirus (HPV) infection can cause cervical and other cancers, including vulva, vagina, penis, anus, or oropharynx. However, in China's northern Henan Province, data on the prevalence and genotype distribution of HPV among women attending gynecology clinics is limited. This study aimed to investigate the current prevalence and genotype distribution of HPV among women attending gynecology clinics in northern Henan Province. Methods This study included 15,616 women aged 16–81 years old who visited the Xinxiang central hospital's gynecology department between January 2018 and December 2019. HPV DNA was detected by a conventional PCR method followed by HPV type-specific hybridization, which was designed to detect 17 high-risk HPV (HR-HPV) genotypes and 20 low-risk HPV (LR-HPV) genotypes. HPV prevalence and corresponding 95% confidence intervals (95% CI) were calculated using SPSS 18.0. Results The overall HPV prevalence was 19.7% among women in northern Henan Province. Single, double, and multiple HPV infections accounted for 13.7%, 4.3%, and 1.8% of the total cases. Most infections were caused by HR-HPV (71.8%), and single genotype HPV infection (13.7%) was the most common pattern. The most common HR-HPV genotype was HPV16 (4.3%), followed by HPV52 (3.5%) and HPV58 (2.0%). The most common LR-HPV genotype was HPV6 (1.4%), followed by HPV61 (1.1%) and HPV81 (1.1%). Conclusions HPV infection is high among women attending gynecology clinics in northern Henan Province. The highest prevalence was found in women less than 20 years old. In northern Henan Province, the 9-valent HPV vaccine is strongly recommended for regular immunization.

Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

AbstractHost cell DNA methylation analysis in urine provides promising triage markers for women diagnosed with a high-risk (HR) human papillomavirus (HPV) infection. In this study, we have investigated a panel of six host cell methylation markers (GHSR, SST, ZIC1, ASCL1, LHX8, ST6GALNAC5) in cervicovaginal secretions collected within the first part of the urine void (FVU) from a referral population. Cytology, histology, and HPV DNA genotyping results on paired FVU and cervical samples were available. Urinary median methylation levels from HR-HPV (n = 93) positive women were found to increase for all markers with severity of underlying disease. Significantly elevated levels were observed for GHSR and LHX8 in relation to high-grade cervical intraepithelial neoplasia (CIN2 +; n = 33), with area under de curve values of 0.80 (95% Confidence Interval (CI) 0.59–0.92) and 0.76 (95% CI 0.58–0.89), respectively. These findings are the first to support the assertion that methylation analysis of host cell genes is feasible in FVU and holds promise as molecular, triage strategy to discern low- from high-grade cervical disease in HR-HPV positive women. Molecular testing on FVU may serve to increase cervical cancer screening attendance in hard-to-reach populations whilst reducing loss to follow-up and await further optimization and validation studies.

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.

Our study is aimed at evaluating the presence of p53 and Ki67 expression by immunohistochemistry in a series of 11 paraffin-embedded penile carcinomas. We also investigated the presence of Human Papillomavirus (HPV) DNA in these tumours and performed an accurate typing by DNA sequencing on positive samples. Immunohistochemistry (IHC) was performed with the anti-p53 and Ki67 mouse monoclonal antibodies. DNA extracted from small sections of each specimen was submitted to amplification with HPV specific general primers; PCR products of the proper length were purified and sequenced. IHC demonstrated nuclear accumulation of mutated p53 and Ki 67 expression in 10/11 tumour samples (90.9%). The prevalence of HPV DNA was 72.7%; the most prevalent type was HPV16. Sequencing analysis revealed the presence of HPV53 (12.5%), HPV18 (25%) and HPV16 (62.5%). Out of the p53 or Ki67 positive carcinomas the percentage of HPV positives was 80% and 70% respectively. Our results indicate that penile carcinoma is frequently associated to high risk HPV and with diffuse p53 and Ki67 expression.

Human papillomavirus (HPV) high risk genotype infection and HPV viral load influences the development of invasive cervical cancer and cervical intra-epithelial neoplasia (CIN). HPV DNA testing for screening of cervical cancers may play a potential role in its early detection and management. The present study detected HPV DNA and estimated HPV viral load in different types of cervical lesions among Bangladeshi women. Using the Hybrid Capture 2 (HC2) assay, HPV DNA was tested among 68 women between 25-70 years of age. A total of 13 (19.1%) cases were positive for HPV DNA. The highest viral load (501 x 10³ copies/ml) was detected in a patient with invasive carcinoma, while the lowest viral load (105 x 10³ copies/ml) was detected from a case of chronic cervicitis. The mean viral load in CIN I was 119.25 x 10³±12.5 x 10³ copies/ml (range: 110 x 10³ - 137 x 10³) and 208.50 x 10³ ± 0.59 x 10³ copies/ml (range: 139 x 10³-305 x 10³) in CIN II / III. Interestingly, HPV DNA was detected from a patient with normal cytological findings. Our study observed a moderate presence of high-risk HPV genotypes among women with cervical lesions. The HPV viral load varied with the age of the patients and stage of cervical lesions. The HC2 assay is a promising tool for diagnosing high-risk HPV infection especially before cytology tests show any abnormality.

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.
