Prevalence and distribution of human papillomavirus genotypes among women in northern Henan Province of China

Abstract Background Human papillomavirus (HPV) infection can cause cervical and other cancers including cancer of vulva, vagina, penis, anus, or oropharynx. However, data concerning the prevalence and genotype distribution of HPV among women are limited in northern Henan Province of China. This study aimed to make an investigation on the current prevalence and genotype distribution of HPV among women and provided comprehensive data to guide HPV-based cervical cancer prevention in northern Henan Province. Methods A total of 15616 women aged 16 to 81 years who attended the department of gynecology of Xinxiang central hospital between January 2018 and December 2019 were enrolled in this study. HPV DNA was detected by PCR method followed by HPV type-specific hybridization. The overall prevalence, age-specific prevalence and genotype distribution of HPV were investigated. 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, respectively. HPV prevalence was 41.8% among women aged 16 to 19 years, 21.1% among women aged 20 to 29 years, 18.1% among women aged 30 to 39 years, 17.7% among women aged 40 to 49 years, 20.8% among women aged 50 to 59 years, 22.9% among women more than 60 years. HPV infection rates differed significantly across different age groups. Most infections were caused by high-risk HPV (HR-HPV) and single genotype HPV infection was the most common pattern. The most common HR-HPV genotype was HPV16, followed by HPV52, HPV58, HPV53 and HPV39. The most common low-risk HPV (LR-HPV) genotype was HPV6, followed by HPV61, HPV81, HPV54 and HPV11. Conclusions HPV infection is common among women in northern Henan Province. The highest infection prevalence was found in women less than 20 years old. The 9-valent HPV vaccine for routine vaccination is strongly recommended in northern Henan Province.

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.

Sexual behavioral and other risk factors and the prevalence of genital human papillomavirus (HPV) infection are very important for the monitoring of HPV infection and cervical cancer prevention strategies. The purpose of this study was to determine the risk factors, prevalence of cervical HPV infection and genotype distribution among asymptomatic young women with normal cytology in Serbia. A total of 204 consenting young women were enrolled in this study and interviewed about risk factors. The presence of HPV DNA was assessed using the PCR method. HPV genotypes were identified by direct sequencing. Cervical HPV infection was detected in 19.1% of women. Out of nine identified HPV genotypes, types 16 and 52 were the most frequent. A significant association was found only between the number of sexual partners and HPV positivity (p<0.05). The obtained results showed the high prevalence of high-risk HPV types among young women in Serbia.

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.

In order to determine the prevalence and genotype distribution of human papillomavirus (HPV) infection in patients with nasal polyps, a total of 204 patients with nasal polyps and 36 healthy controls were recruited for this study. Genomic DNA was extracted from paraffin-embedded tissue sections. HPV DNA genotyping was achieved by a flow-through hybridization and gene-chip method. HPV-positive infection was identified in 82 of 204 (40.2 %) patients, while HPV DNA was not found in healthy controls (P<0.05). Genotyping analysis showed that low-risk HPV genotype 11 was the most prevalent type of HPV in nasal polyps (45.28 %). Both single and multiple HPV genotype infections were found in these HPV-positive cases, although most (74.39 %) were infected with a single genotype. In addition, there was no correlation between HPV infection or HPV subtypes and the clinicopathological characteristics of patients, such as age, gender, number of surgery and disease course. The data from our study clearly demonstrated that HPV infection was associated with nasal polyps. Both high-risk HPV and low-risk HPV (LR-HPV) genotypes were identified in nasal polyp tissues, and LR-HPV-11 was the most prevalent type. Future research will explore the association of HPV infection with the development and progression of nasal polyps.

Investigations of human papillomavirus (HPV) in the glans penis are scarce, especially with regard to its natural history. To elucidate HPV prevalence among Japanese men attending urological clinics, 798 adult participants were recruited consecutively and stratified into groups by age based on 10-year intervals. The overall HPV prevalence among the participants was 24.8%, with 15.5% positive for high-risk HPV and 9.3% infected with other HPVs. The HPV positivity rate was sustained in those over 80 years of age at nearly the same level as those in the younger age groups. We also determined the age at last sexual intercourse of 15 HPV-positive participants in the 80+ years age group. In addition, six participants positive for HPV were re-examined for HPV and all showed nearly the same HPV types as those identified in their first examinations. The difference between the age at the first test and the age of last intercourse was 8.3 ± 6.2 years. Except for the elderly group who reported sexual intercourse within the previous year, the duration was 10.0 ± 5.1 years. Our data suggest an HPV persistence of at least eight years. Further investigation is necessary to elucidate the long-term persistence of HPV infection in the glans penis.

Background: Human papillomavirus (HPV) infection is the most common sexually transmissible viral infection worldwide. HPV is highly prevalent in sexually active men who have sex with men (MSM). The main objective of this study is to assess HPV prevalence in the oral cavity of MSM from Beirut, Lebanon. Methods: From November 2015 to January 2016, 42 MSM were recruited using respondent-driven sampling and provided oral samples for HPV DNA and for linear array testing to detect HPV type. Results: In total, 28 (66.67%) HIV-negative and 14 (33.33%) HIV-positive MSM were included. Overall, HPV prevalence in the oral cavity was 10% (95% CI 0.93–19.07) among all participants, but there was no statistical difference according to HIV status. The HPV type was exclusively HPV-6. Conclusions: These findings did not find an urgent need for routine HPV prevalence and screening for cancers in the oral cavity of a MSM group in Lebanon; however, they confirm previous findings about geographic variations in HPV prevalences.

The natural history of cervical cancer is strongly related to the presence of human papillomavirus (HPV) infection, with its relationship with cervical cancer being a matter of concern. It is estimated that 70% of all cervical cancers worldwide are caused by HPV 16 and 18. Accordingly, the present study aimed to contribute to the identification of HPV subtypes circulating in a group of women of Manaus-Brazil. Cervical samples were collected from 49 women, following the eligibility criteria of the study, and DNA was then extracted from the samples, which were analyzed for the presence of the virus in the genetic material through the polymerase chain reaction (PCR) using generic primers (GP05/06). Finally, identification of the viral subtypes was performed using specific primers for the detection of the main subtypes already examined (16 and 18). Positive HPV DNA was detected in 100% of the samples included in the study. Human papillomavirus 16 was the most prevalent subtype in the majority of lesions, accounting for 29 (59.2%) of the positive cases, and HPV 18 was detected in four (8.2%) women. In these 4 cases there was co-infection, with the presence of both HPV 18 and HPV 16. Therefore, 40.8% (20 cases) in which HPV DNA was detected presented infection with other subtypes of HPV not included in the study. This data has clinical implications related to cervical cancer prevention, as the current prophylactic HPV vaccines are only effective against high-risk HPV 16 and 18 subtypes.
