[PMID: 38840267 PMCID: PMC11151588 DOI: 10.1186/s12985-024-02393-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 05/18/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND Global human activities were significantly impacted by the emergence of the coronavirus disease 2019 (COVID-19) pandemic caused by the 2019 novel coronavirus. This study aimed to investigate the prevalence and genotype distribution of HPV infection in Central Fujian Province during the pandemic. METHODS Cervical samples were collected from 21,612 outpatients and 12,664 females who underwent physical examinations and HPV screening at the People's Hospital of Fujian Province in Fuzhou from April 2020 to April 2023. HPV detection and genotyping were conducted using PCR hybridization. RESULTS The overall HPV infection rate was 16.1% during the COVID-19 pandemic, with the outpatient group exhibiting a greater infection rate (19.0%) than did the healthy group (12.3%). The top five high-risk HPV (HR-HPV) genotypes in both groups were HPV52, HPV53, HPV58, HPV16, and HPV51. Additionally, HPV81 and HPV43 were the two most common low-risk HPV (LR-HPV) genotypes in the patient group, while HPV81 and HPV42 were the two most common LR-HPV genotypes in the healthy group. The highest prevalence of HPV infection was observed in individuals aged ≤ 24 years (28.4%, 95% CI 25.9-30.9), followed by those aged ≥ 55 years (23.6%, 95% CI 21.6-24.7) and other age groups. The prevalence decreased from 23.0% (95% CI 22.4-23.7) in 2018-2019 to 13.8% (95% CI 12.0-15.5) in 2023. CONCLUSION This study provides valuable insights into the prevalence and genotypes of HPV infection in the female population of Central Fujian Province from 2020 to 2023. The findings indicate that the prevalence of HPV infection in Central Fujian Province remains relatively low compared to the national average. Furthermore, the prevalence of HPV decreased during the COVID-19 pandemic; however, as the pandemic waned, there was potential for an increase in HPV infection rates. Therefore, it is crucial to strengthen HPV screening and vaccination strategies to prevent the potential spread of HPV.

PLoS One 2024; 19:e0299479. [PMID: 38452108 PMCID: PMC10919642 DOI: 10.1371/journal.pone.0299479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 02/09/2024] [Indexed: 03/09/2024] Open
Abstract
INTRODUCTION Human papillomavirus (HPV) is the most common sexually transmitted infection, attributed to 4.5% of all cancers worldwide. Co-infection with the metabolic syndrome (MetS), a common cluster of cardiometabolic risk factors, has been shown to increase the persistence of HPV. The purpose of this study was to estimate the association between HPV and MetS on mortality risk. METHODS Data for the current study was drawn from seven consecutive cycles (2003-2004 to 2015-2016) of the U.S. NHANES. The final analytic sample consisted of 5,101 individuals aged 18-65y with HPV and MetS information with follow-up to Dec. 31st, 2019. Baseline HPV status was assessed by either vaginal swab, penile swab or oral rinse and used to classify participants as: no HPV (n = 1,619), low (n = 1,138), probable (n = 672), and high-risk (n = 1,672; 22% type 16, and 10% type 18) HPV using IARC criteria. MetS was assessed by the Harmonized criteria. RESULTS The average follow-up was 9.4 y with 240 all-cause deaths (no HPV: n = 46 deaths; low-risk: n = 60 deaths; probable: n = 37 deaths, and; high-risk: n = 97 deaths). HPV status alone revealed no associations with mortality in fully adjusted models. Cross-classification into discrete MetS/HPV strata yielded an increased risk of mortality in females with high-risk HPV/MetS relative to the no MetS/no HPV group. CONCLUSIONS In this study, low, probable, and high-risk HPV and MetS were differentially related to mortality risk in men and women. Further work is necessary to separate the temporal, age, vaccination, and sex effects of HPV diagnosis in these relationships using prospective studies with detailed histories of HPV infection and persistence.

Characteristics of human papillomavirus prevalence and infection patterns among women aged 25-64 according to age groups and cytology results in Ordos City, China. Virol J 2024; 21:12. [PMID: 38191450 PMCID: PMC10775550 DOI: 10.1186/s12985-023-02240-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 11/13/2023] [Indexed: 01/10/2024] Open
Abstract
BACKGROUND The assessment of human papillomavirus (HPV) genotype distribution in terms of age and cervical lesions could contribute to the adoption of more targeted preventive approaches to specific populations against cervical cancer. The current study was conducted in Ordos City, China, with the aim of analyzing the HPV genotypes prevalence and infection patterns within a hospital-based population. METHODS The analysis included a total of 26,692 women aged 25-64 who underwent cervical cancer screening between January 1st, 2019, and June 30th, 2022, in Ordos City. These women had valid results for both the polymerase chain reaction (PCR)-reverse dot blot (RDB) HPV test and the liquid-based cytology (thinprep cytologic test/TCT). Data were extracted from the database of KingMed Diagnostics laboratories. The prevalence of HPV genotypes within different age groups and cytology diagnoses were calculated. RESULTS Among 26,692 women, 7136 (26.73%) women were HPV positive, 5696 (21.34%) women were high-risk HPV (HR-HPV) positive, and 2102 (7.88%) women had multiple HPV infections. The most frequently detected HPV genotypes were HPV16 (4.72%) and HPV52 (4.15%), ranking as the first and second most prevalent genotypes, respectively. The prevalence of HR-HPV increased with age groups and severity of cervical lesions. Notably, the positive rate of HR-HPV among women aged 35-64 years showed a decreasing trend over the respective years, ranging from 26.00 to 19.70% (Ptrend < 0.001). CONCLUSION In conclusion, the epidemiology of HPV genotypes partly reflects the effectiveness of regional cervical cancer prevention and control efforts in the past. These findings can inform future initiatives concerning HPV vaccination and screening in the region.

Abstract
BACKGROUND Cervical cancer is the fourth most common cancer among women worldwide with a serious threat to women's health. Persistent infection with high-risk human papillomavirus (HR-HPV) has been identified as the main cause of cervical cancer. This study aimed to evaluate the prevalence and genotype distribution of HR-HPV among women in Jingzhou, Hubei province, China, which is critical for the government to formulate the precision strategies of cervical cancer screening and HPV vaccine innoculation. METHODS To obtain the baseline data on the population-based prevalence and genotype distribution of HR-HPV infection among age groups and different years, a total of 51,720 women from 2018 to 2022 who went to Jingzhou Hospital Affiliated to Yangtze University for physical examination or gynacological treatment and received HR-HPV DNA genotyping were included in this retrospective study. The possible cervicovaginal infection of 15 high-risk HPV genotypes were analyzed by multiplex fluorescent real-time PCR, including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68 and 82. RESULTS The overall high-risk HPV prevalence among 51,720 women was 18.75% (9,698/51,720), and the HPV-positive rate of physical examination group (PEG) was 13.22% (541/4,091), which was lower than the HPV-positive rate of gynacological checkup group (GCG) 19.23% (9,157/47,629), with statistical difference (χ2 = 89.069, P < 0.01). The five most common prevalent genotypes were HPV52 (6.55%), HPV58 (3.41%), HPV16 (2.58%), HPV68 (1.82%) and HPV51 (1.57%). Single HPV infection was the predominant (14.36%), which compared to double (3.34%) and multiple (1.05%) infections. The HPV-positive rate was the highest in the > 60 age group (31.73%), and the lowest in the 31-40 age group (15.46%). CONCLUSIONS The prevalence of high-risk HPV infection among women in Jingzhou area was 18.75%. HPV52, HPV58 and HPV16 genotypes were the most common. The higher prevalence was in the > 60 and ≤ 20 age group, which showed a "U" shape curve, suggesting the necessity of screening among older women to decrease the mortality of cervical cancer.

The features of high-risk human papillomavirus infection in different female genital sites and impacts on HPV-based cervical cancer screening. Virol J 2023; 20:116. [PMID: 37280665 DOI: 10.1186/s12985-023-02073-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Accepted: 05/16/2023] [Indexed: 06/08/2023] Open
Abstract
BACKGROUND The causal role of high-risk Human papillomavirus (HR-HPV) in the pathogenesis of anogenital cancers is well established. In contrast, information on HR-HPV distribution of continuous anatomic sites within the female genital tract is limited, and the impact of sample type on the clinical performance in HPV-based cervical cancer screening warrants investigation. METHODS A total of 2,646 Chinese women were enrolled in the study from May 2006 to April 2007. We analyzed the infection features by infection status and pathological diagnoses of 489 women with complete HR-HPV type and viral load data on the cervix, upper vagina, lower vagina, and perineum samples. Additionally, we assessed the clinical performance for detecting high-grade cervical intraepithelial neoplasia of grade two or worse (≥ CIN2) among these four types of samples. RESULTS HR-HPV positivity rate was lower in the cervix (51.53%) and perineum (55.83%), higher in the upper (65.64%) and lower vagina (64.42%), and increased with the severity of cervical histological lesions (all P<0.001). Single infection was more dominant than multiple infections at each anatomic site of the female genital tract. The proportion of single HR-HPV infection decreased successively from the cervix (67.05%) to the perineum (50.00%) (Ptrend=0.019) in cervical intraepithelial neoplasia grade 1 (CIN1) and was higher in samples of the cervix (85.11%) and perineum (72.34%) in ≥ CIN2. In addition, the highest viral load was observed in the cervix compared to the other three sites. The overall agreement of the cervical and perineum samples was 79.35% and increased continuously from normal (76.55%) to ≥ CIN2 (91.49%). As for the detection of ≥ CIN2, the sensitivity was 100.00%, 97.87%, 95.74%, and 91.49% for the cervix, upper vagina, lower vagina, and perineum samples, respectively. CONCLUSIONS Single HR-HPV infection predominated throughout the female genital tract, but the viral load was lower compared to multiple HR-HPV infections. Despite the decreasing viral load from cervix to perineum, the clinical performance for detecting ≥ CIN2 of the perineum sample was comparable to that of the cervix.

Characteristics of human papillomavirus infection among females and the genetic variations of HPV18 and HPV58 in Henan province, China. Sci Rep 2023; 13:2252. [PMID: 36755053 PMCID: PMC9908864 DOI: 10.1038/s41598-022-24641-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Accepted: 11/17/2022] [Indexed: 02/10/2023] Open
Abstract
The present study aims to investigate the genotype distribution of Human papillomavirus (HPV) and variations of HPV18 and HPV58 infection among 6538 females in Luoyang city during 2019-2021. The overall positive rate of females with HPV infection was 12.34%, with 9.74% were infected with single HPV and 2.60% with multiple HPVs. The prevalent rate of high-risk HPV (HR-HPV) was 9.85% and the top five HR-HPV genotypes were HPV52 (1.94%), HPV16 (1.93%), HPV58 (1.48%), HPV51 (1.02%) and HPVV39 (0.99%). Two peaks of HPV infections rates were observed in females aged ≤ 20 and 61-65 years old. To characterize mutations, 39 HPV18 and 56 HPV58 L1, E6 and E7 genes were sequenced and submitted to GenBank. In the HPV18 E6-E7-L1 sequences, 38 nucleotides changes were observed with 10/38 were non-synonymous mutations (5 in E6 gene, 1 in E7 gene and 4 in L1 gene). In the HPV58 E6-E7-L1 sequences, 53 nucleotides changes were observed with 23/53 were non-synonymous mutations (3 in E6 gene, 5 in E7 gene and 15 in L1 gene). Phylogenetic analysis based on L1 gene showed that 92.3% (36/39) of HPV18 isolates fell into sublineage A1 and 7.7% (3/39) belonged to A5. For HPV58, 75.0% (42/56) isolates belonged to sublineage A1 and 25.0% (14/56) were sublineage A2. There was no association between amino mutation and cervical lesions. The present study provides basic information about the distribution, genotypes and variations of HPV among females population in Luoyang city, which would assist in the formulation of HPV screening and vaccination programs and preventive strategies for HPV-attributable cancer in this region.

Abstract
BACKGROUND The rising prevalence of high-risk human papillomavirus (HR-HPV) type-related diseases pose an ongoing health challenge in China. In this study, we assessed the current views of the general public of the Guizhou Province on HPV and HPV vaccinations to provide recommendations for future directions regarding the rollout of HPV vaccination in the area. METHODS An online questionnaire survey was conducted that included 3412 (2532 females and 880 males) native adult residents of the Guizhou Province. Data on the socio-demographic characteristics, knowledge of HPV, and perceptions of HPV vaccinations were collected. Data comparisons were made between students and non-students and between participants with and without medical backgrounds. All statistical analyses were performed using SPSS 26.0. RESULTS The self-reported HPV infection rates were 5.85% in women and 0.86% in men. A total of 46.29% of women and 34.43% of men achieved acceptable knowledge levels of HPV and 47.54% of women possessed an acceptable knowledge level of HPV vaccines. Non-students and medical participants performed significantly better in the knowledge tests than their respective opposing groups. Online media was the most popular HPV information source for all the participants. A total of 93.58% of women and 87.88% of men expressed willingness toward HPV vaccination. The major facilitators of vaccination acceptance were females (OR = 1.932, 95% CI: 1.390-2.685, p < 0.001) or students (OR = 2.276, 95% CI: 1.207-4.291, p = 0.011), and participants with higher HPV knowledge level (OR = 1.796, 95% CI: 1.300-2.481, p < 0.001). Ages 41-50 (OR = 0.255, 95% CI: 0.121-0.538, p = 0.001) or > 50 (OR = 0.141, 95% CI: 0.059-0.337, p < 0.001) were significant predictors of a negative attitude towards HPV vaccination. CONCLUSION Guizhou residents had poor knowledge of HPV-related issues. The percentage of healthcare workers who achieved acceptable knowledge levels was one-half or less. The increasing HPV prevalence and cervical cancer incidence can be contained if more affordable vaccines are developed and the low knowledge levels pervading young adults and medical staff is eliminated.

Abstract
BACKGROUND Certain types of human papillomavirus (HPV) induce long-lasting infections that cause cervical cancer. This study evaluated the prevalence of HPV infections and the distribution of their genotypes among clinic patients and healthy women in Beijing, China. METHODS Cervical specimens were collected from 12,100 patients and 1176 subjects who underwent physical examinations at Dongzhimen Hospital, Beijing University of Chinese Medicine, between March 2016 and September 2020. HPV genotyping was performed using commercial kits designed to detect 15 high-risk and 2 low-risk HPV genotypes. RESULTS There was a higher overall prevalence of HPV among the clinic patients (21.0%) than among the healthy women (11.9%). The most common HPV genotypes among the patients were: HPV-52 (5.4%), HPV-16 (3.4%), HPV-58 (3.2%), HPV-51 (2.6%), HPV-39 (2.0%), HPV-56 (2.0%), and HPV-66 (2.0%). Among the healthy women: HPV-52 (3.0%), HPV-51 (1.8%), HPV-58 (1.6%), HPV-66 (1.5%), HPV-16 (1.2%), HPV-56 (1.2%), and HPV-18 (1.1%). Multiple HPVs were detected in 29.1% of the gynecological outpatients and in 23.6% of the women receiving physical examinations. The most common pairs of HPV types detected were HPV-52 and HPV-16 in the clinic patients, and HPV-52 and HPV-56 in the healthy women. Age-specific HPV positivity and peak prevalence were observed among the individuals in both groups for women aged less than 25 years and those between 61 and 65 years of age. CONCLUSIONS Our results provide current estimates of HPV prevalence and genotypes in the Beijing region. The epidemiological characteristics observed also provide a reference for the development of cervical cancer screening strategies and selection of HPV vaccine antigen targets for this region. A comparison of these HPV prevalence data with those from other regions suggests that regional vaccines may be an important direction for future research.

Abstract
Introduction: This study investigates unexplained infertile women with or without chronic endometritis (CE) and examines the prevalence of the human papillomavirus (HPV) in this population.
Material and Method: This study was done with a cross-sectional and retrospective method. The prevalence of HPV infection and related cases in the participants were examined. In this study, 15 infertile women with CE and 64 infertile women without CE were and analyzed from four perspectives: negative HPV, low-risk HPV, probable high-risk HPV, and the presence of high-risk HPV.
Results: The participants have mean age of 32.89 years ±3.95. High-risk HPV infection was detected in 3 (20%) and 11 (17%) of the patients with and without CE, respectively (p>0.05). The negative HPV (2 (13%) and 17 (26%)), low-risk HPV (3 (20%) and 20 (31%)), and probable high-risk HPV (7 (46%) and 16 (25%)) in infertile women with CE and infertile women had no significantly different prevalence (p>0.05). The two studied groups had no significantly different mean age, body mass index (BMI), and Infertility duration were not in (P=0.08, P=0.932, and P=0.283, respectively).
Conclusion: HPV has no significantly different prevalence in unexplained infertile women with and without CE. It is recommended that this study be repeated with more unexplained infertile women with CE.

Abstract
Background Persistent high-risk Human papillomavirus (HPV) subtypes infection has been implicated as a causative of cervical cancer. Distribution and genotypes of HPV infection among females and their variations would assist in the formulation of preventive strategy for cervical cancer. The purpose of the present study is to investigate the prevalence of HPV among females in central China. Methods The distribution and genotypes of HPV among 9943 females attending the gynecological examinations in central of China during 2015–2021 were investigated. HPV genotypes were detected using a commercial kit. Nucleotides sequences of L1, E6 and E7 genes in HPV16 or HPV52 positive samples collected in 2021 were amplified by polymerase chain reaction (PCR). Variations of L1, E6 and E7 in HPV16 and HPV52 were gained by sequencing and compared with the reference sequence. Sublineages of HPV16 and HPV52 were determined by the construction of phylogenetic tree based on L1 gene. Results The overall prevalence of HPV infection was 22.81%, with the infection rate of high-risk human papillomavirus (HR-HPV) was 19.02% and low-risk human papillomavirus (LR-HPV) was 6.40%. The most top five genotypes of HPV infection were HPV16 (7.49%), HPV52 (3.04%), HPV58 (2.36%), HPV18 (1.65%) and HPV51 (1.61%). Plots of the age-infection rate showed that the single HPV, multiple HPV, HR-HPV, LR-HPV infection revealed the same tendency with two peaks of HPV infection were observed among females aged ≤ 20 year-old and 60–65 year-old. The predominant sublineage of HPV16 was A1 and B2 for HPV52. For HPV16, The most prevalent mutations were T266A (27/27) and N181T (7/27) for L1, D32E for E6 and S63F for E7 in HPV16. For HPV52, all of the nucleotide changes were synonymous mutation in L1 (except L5S) and E7 genes. The K93R mutation was observed in most HPV52 E6 protein. Conclusions The present study provides basic information about the distribution, genotypes and variations of HPV among females population in Henan province, which would assist in the formulation of preventive strategies and improvements of diagnostic probe and vaccine for HPV in this region.

Abstract
Objective Despite the fact that the human papillomavirus vaccine (HPVV) has been approved in mainland China since 2016, there is a lack of inoculation among Chinese college women. This multi-center, online interventional RCT based on the information-motivation-behavioral skills (IMB) model intended to investigate if the intervention may improve human papillomavirus vaccine acceptance and awareness among target women. Methods Participants were selected from comprehensive universities and allocated to 1 of 2 groups: intervention or control. After the baseline survey, participants in the intervention group were given 10-minute online IMB model-based education every day for 7 days. Self-administered questionnaire surveys on Human papillomavirus knowledge, HPVV acceptability, and IMB construct toward HPV vaccination were performed at pre- and post-intervention. Results The baseline survey was completed by 3739 female university students from the intervention (n = 1936) and control groups (n = 1803) between February and April 2020. The average score of students on 11 HPV-related questions was 5.225 ± 2.739, and only 32.07% (1199/3739) of them showed a willingness to be vaccinated against HPV. After the intervention, the intervention group had a higher willingness to vaccinate themselves and encourage their friends to get the HPVV compared to the control group (40.39% vs 31.56%, 82.67 vs 73.18%, P < .001), and the difference in knowledge scores between the 2 groups was significant (7.917 ± 1.840 vs 5.590 ± 2.859, P < .001). In addition, 8 students in the intervention group self-reported receiving HPVV during the research period. Conclusions This IMB model-based intervention showed positive effects on the participants’ knowledge, motivation, and perceived objective skills toward HPV vaccination and has the potential to improve the vaccination among Chinese college women.

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
This paper aimed to investigate the characteristics of female HPV infection in the Shangcheng District, Hangzhou city, China. The retrospective study was designed to analyze the HPV prevalence rate of 22,382 women receiving physical examinations from 2016 to 2020 in the Shangcheng District of Hangzhou city in China. A commercial kit was designed to detect the HPV genotypes. Trends were examined for age-specific groups (≤ 30 years, 31–44 years, 45–54 years, 55–64 years, ≥ 65 years). A receiver operating characteristic (ROC) analysis was used to assess the correlation of age classification in high risk HPV (HR-HPV) infection. 22.41% (5015/22,382) of samples were HPV positive, 91.28% (4578/5015) of HPV positive women were infected by HR-HPV. The most prevalent HR-HPV genotypes were 16, 52, 18, 58, 56, and 51. The trend of HPV prevalence showed the significant differences in age-specific groups (χ2 = 164.70, P < 0.001). Moreover, the areas under ROC curve (AUC) was 0.712 in 55–64 years group which showed a strong contribution of age classification for HR-HPV infection. This study provided baseline data on the prevalence characteristics of HPV infection and the critical age group of HR-HPV prevalence rate was 55–64 y among the samples receiving physical examinations.

Abstract
Cervical cancer (CC) is highly associated with high-risk human papillomavirus (HPV) infection and genotype distribution of high-risk HPV (HR-HPV) infection varies greatly in different regions. Clinical specimens were collected from 46 365 patients at Beijing Friendship Hospital, Capital Medical University from January 2017 to December 2020. HPV DNA genotype testing was performed using real-time PCR. The infection rates based on disease group were compared using the χ 2 test. The linear-by-linear association test and gamma value were used to assess the changes in HPV prevalence over calendar year and age group. A total of 10 514 women were infected with HR-HPV, with an overall positive rate of 22.7%. The most prevalent HR-HPV types were HPV52, 58, 16, 51, and 66, and HPV59 had a higher prevalence except for HPV16, 58, and 52 in the CC group. Single infection of HR-HPV was dominant among different disease groups. The infection rate of HR-HPV decreased first and then increased from below 20 years old to over 60 years old. There were significant differences in the HR-HPV infection rates among the age and disease groups. Our findings demonstrate that the genotype distribution of HR-HPV varied with age and diseases. The HR-HPV genotypes prevalence was found to be directly useful for local governments to promote HPV targeted vaccination in the study region.

Abstract
Human papillomavirus (HPV)-based cervical screening is a globally recommended health policy. Different HPV types have different risk for cervical cancer. For optimal HPV screening, the sensitivity and specificity for each HPV type at different viral loads should be known in a screening setting. HPV test results in about 1 million cervical samples analyzed during 2006 to 2014 were compared for 319 women who had developed invasive cervical cancer up to 8.5 years later and for 1911 matched control women. Detection including low viral loads resulted in markedly increased sensitivity for cervical cancer only for HPV types 16 and 18. Testing for HPV types 31, 33, 45 and 52 also increased the sensitivity for prediction of cervical cancer, but for these viruses, detection of low viral load did not further increase sensitivity. HPV types 35, 39, 51, 56, 58, 59, 66 and 68 only predicted occasional additional cervical cancer cases. Testing for HPV16/18 at low viral load plus testing for HPV31, 33, 45 and 52 at >3000 copies/μL predicted 86.5% of cancers occurring within a year after testing, similar to the 89.4% that were predicted by testing for 14 HPV types. By contrast, the type and viral load-restricted testing greatly increased specificity: 6.3% of healthy women tested positive as compared to 11.7% of healthy women testing positive for the 14 HPV types commonly screened for today. Adequate HPV screening sensitivity, with considerable increase in specificity, can be obtained by testing only for HPV16/18/31/33/45/52, with detection of low viral load required only for HPV16/18.

Abstract
OBJECTIVE The HPV vaccine has been licensed in mainland China since 2017. This study aimed to assess the epidemiological characteristics of HPV genotypes in the pre-vaccine era in China. METHODS We conducted a multicentric population-based study nested in the largest health clinic chain in China. Between January 1, 2017 and December 31, 2017, 427,401women aged 20 years or older with polymerase chain reaction-based HPV genotyping tests were included in the study. The cervicovaginal infection of 14 high-risk HPV genotypes and 9 low-risk genotypes was assessed using adjusted prevalence, multivariable logistic regression, cluster analysis, and heatmap. RESULTS HPV prevalence was 15.0% (95% confidence interval [CI]: 14.1-15.9%) in China, with high- and low-risk genotypes being 12.1% (95%CI: 11.4-12.7%) and 5.2% (95%CI: 4.8-5.7%), respectively. The prevalence of HPV genotypes corresponding to bivalent, quadrivalent, and nonavalent vaccines were 2.1%, 2.4%, and 8.3%, respectively, whereas the prevalence of non-vaccine high-risk genotypes was 5.7%. The most common high-risk genotypes were HPV-52 (3.5%), HPV-58 (2.1%), and HPV-16 (1.6%), and the prevalence of HPV-18 (0.6%), HPV-6 (0.1%), and HPV-11 (0.2%) were relatively low. Infection with HPV genotypes differed significantly across age groups and geographic locations. CONCLUSION HPV prevalence was high in the pre-vaccine era in China, and a population-based HPV vaccination strategy is needed in the future.

Abstract
Persistent high-risk (HR) human papillomavirus (HPV) infection is an essential risk factor for cervical carcinoma and precancerous lesion. There are differences in HPV distribution among different countries, regions and ethnic groups. The aim of this research was to reveal the epidemiological characteristics of HPV in Chongqing, China. In this study, 13,788 women aged 18 to 78 were screened for 23 HPV genotypes by PCR-reverse dot blot hybridization. The total HPV-positive rate was 19.9% (2,745/13,788), while the positive rates for HR, and low-risk (LR) HPV were 17.3% (2,379/13,788), and 4.6% (638/13,788), respectively. In addition to cervical cancer (CC) and cervical intraepithelial neoplasia (CIN) patients, the HPV infection rates among infertile women and women with gynecological diseases were markedly higher than that among healthy women. The HPV and HR-HPV infection rates in the different age groups showed statistically significant differences, and the prevalence peaks were observed in women under 20 years and over 50 years of age. Overall, HPV-52, HPV-16 and HPV-58 ranked as the top 3 most common subtypes among women in Chongqing. The results of this research provide epidemiological information regarding HPV infection in Chongqing. These data constitute valuable evidence for the prevention and management of cervical carcinoma and development of HPV vaccines.

Abstract
Background Human papillomavirus (HPV) infection is the leading cause of genital diseases. It can cause a series of cervical lesions. The distribution of HPV genotypes indicates that the increased prevalence of high-risk HPV (HR-HPV) is positively correlated with the severity of cervical lesions. In addition, persistent HR-HPV infection is associated with the risk of cervical cancer. Considering the latest approval of homemade HPV vaccine in China and the prevalence of HPV distribution, this is of great significance for guiding HPV vaccination work. Objective Our study’s purpose was to examine trends of cervical HPV infection rate in each 5-year age group from 2011 to 2019. Methods Retrospective analysis of human papillomavirus prevalence rate of 59,541 women from 2011 to 2019 in the District Zhoupu of Shanghai City in China. HPV genotype testing is performed using a commercial kit designed to detect 15 high-risk HPV genotypes and 6 low-risk HPV genotypes. Trends were examined for each 5-year age group. Results In the District Zhoupu of Shanghai City in China, the prevalence rate of cervical HPV increased significantly among women aged 15–34 years. The most prevalent HR-HPV genotypes were 52, 16, 58, 53, 39, and 51. Conclusion Cervical HPV prevalence rate is very high in younger women in suburb Shanghai. Due to significant differences in infection rates between specific age groups and HPV subtypes, timely intervention is required for these vulnerable populations.

[PMID: 32204370 PMCID: PMC7150828 DOI: 10.3390/v12030333] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 03/15/2020] [Accepted: 03/15/2020] [Indexed: 12/12/2022] Open
Abstract
At present, the clinical detection method of human papillomavirus (HPV) is mainly based on the PCR method. However, this method can only be used to detect HPV DNA and HPV types, and cannot be used to accurately predict cervical cancer. HPV16 E7 is an oncoprotein selectively expressed in cervical cancers. In this study, we prepared an HPV16 E7-histidine (HIS) fusion oncoprotein by using a prokaryotic expression and gained several mouse anti-HPV16 E7-HIS fusion oncoprotein monoclonal antibodies (mAbs) by using hybridoma technology. Two mAbs, 69E2 (IgG2a) and 79A11 (IgM), were identified. Immunocytochemistry, immunofluorescence, immunohistochemistry, and Western blot were used to characterize the specificity of these mAbs. The sequences of the nucleotide bases and predicted amino acids of the 69E2 and 79A11 antibodies showed that they were novel antibodies. Indirect enzyme-linked immunosorbent assay (ELISA) with overlapping peptides, indirect competitive ELISA, and 3D structural modeling showed that mAbs 69E2 and 79A11 specifically bound to the three exposed peptides of the HPV16 E7 (HPV16 E749–66, HPV16 E773–85, and HPV16 E791–97). We used these two antibodies (79A11 as a capture antibody and 69E2 as a detection antibody) to establish a double-antibody sandwich ELISA based on a horseradish peroxidase (HRP)-labeled mAb and tetramethylbenzidine (TMB) detection system for quantitative detection of the HPV16 E7-HIS fusion oncoprotein, however, it was not ideal. Then we established a chemiluminescence immunoassay based on a labeled streptavidin-biotin (LSAB)-ELISA method and luminol detection system—this was sufficient for quantitative detection of the HPV16 E7-HIS fusion oncogenic protein in ng levels and was suitable for the detection of HPV16-positive cervical carcinoma tissues. Collectively, we obtained two novel mouse anti-HPV16 E7 oncoprotein mAbs and established an LSAB-lumino-dual-antibody sandwich ELISA method for the detection of the HPV16 E7-HIS fusion oncogenic protein, which might be a promising method for the diagnosis of HPV16-type cervical cancers in the early stage.

Human Papillomavirus (HPV) Vaccine Uptake and the Willingness to Receive the HPV Vaccination among Female College Students in China: A Multicenter Study. Vaccines (Basel) 2020; 8:E31. [PMID: 31963370 PMCID: PMC7157221 DOI: 10.3390/vaccines8010031] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 12/30/2019] [Accepted: 01/14/2020] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND This study aimed to determine human papillomavirus (HPV) vaccine uptake and willingness to receive HPV vaccination among female college students, in China, and its associated factors. METHODS An online cross-sectional survey of female college students across the eastern, central, and western regions of China was undertaken between April and September 2019. Partial least squares structural equation modeling (PLS-SEM) was used to examine factors associated with the HPV vaccine uptake and willingness to receive the HPV vaccine. RESULTS Among the total 4220 students who participated in this study, 11.0% reported having been vaccinated against HPV. There are direct effects of indicators of higher socioeconomic status, older age (β = 0.084 and p = 0.006), and geographical region (residing in Eastern China, β = 0.033, and p = 0.024) on HPV vaccine uptake. Higher knowledge (β = 0.062 and p < 0.000) and perceived susceptibility (β = 0.043 and p = 0.002) were also predictors of HPV vaccine uptake. Of those who had not received the HPV vaccine, 53.5% expressed a willingness to do so. Likewise, social economic status indicators were associated with the willingness to receive the HPV vaccine. Total knowledge score (β = 0.138 and p < 0.001), both perceived susceptibility (β = 0.092 and p < 0.001) and perceived benefit (β = 0.088 and p < 0.001), and sexual experience (β = 0.041 and p = 0.007) had a positive and significant direct effect on the willingness to receive the HPV vaccine, while perceived barriers (β = -0.071 and p < 0.001) had a negative effect on the willingness to receive the HPV vaccine. CONCLUSIONS Geographical region and socioeconomic disparities in the HPV vaccination uptake rate and willingness to receive the HPV vaccine provide valuable information for public health planning that aims to improve vaccination rates in underserved areas in China. The influence of knowledge and perceptions of HPV vaccination suggests the importance of communication for HPV immunization.

Abstract
Objective To formulate strategies for prevention of cervical cancer, we investigated the prevalence of human papillomavirus (HPV) infection and the age-specific distribution among female participants in southeastern China. Methods From January 2016 to July 2018, 36,871 women from Meizhou People’s Hospital (Huangtang Hospital), Meizhou Hospital Affiliated to Sun Yat-sen University were enrolled in this prospective study. HPV genotypes were detected using Luminex technology. Results HPV infection was observed in 18.34% of the participants, and 79.98% were infected with high-risk HPVs. The five most prevalent genotypes were HPV52 (18.18%), HPV16 (16.06%), HPV58 (11.37%), HPV53 (8.82%), and HPV39 (6.42%). The 9-valent HPV vaccine efficiently reduced the HPV infection rate by more than 10%, which is twofold the rate of other vaccines. Most HPV infections were observed in women age 40 to 49 years, and those age 30 to 59 years accounted for 79.62% of positive patients. Conclusion Our findings regarding HPV genotypes and the age-specific distribution of HPV infection in the study area will contribute to the development of cervical cancer screening programs and vaccine strategies.

Abstract
Human papillomavirus (HPV) infection is the leading cause of cervical cancer and precancerous lesions. Knowledge regarding the prevalence and genotype distribution of HPV in women is important to establish strategies for cervical cancer screening and HPV vaccination. This study aimed to evaluate the characteristics of HPV infection in Taizhou, China. HPV genotype of 10,733 women who visited Taizhou People's Hospital from November 2016 to October 2018 was determined using a PCR and hybridization-based detection test. The prevalence of overall, high risk (HR), and low risk (LR) HPV infections was 34.58%, 29.92%, and 10.12%, respectively. Of HPV-positive cases, 2417 (65.13%) were infected with a single HPV genotype and 1294 (34.87%) were infected with multiple HPV genotypes. HPV-52 was the most prevalent genotype (6.21%), followed by HPV-16 (5.33%), HPV-53 (4.03%), HPV-58 (3.89%), and HPV-81 (3.75%). The highest prevalence of HPV infection was found in women aged ≥60 years (40.72%). Furthermore, the prevalence of HPV increased with the severity of cervical lesions. In conclusions, the prevalence and genotype distribution of HPV varied with age and cervical lesions. The findings might serve as a potential reference for guiding cervical cancer screening and vaccine-based HPV prevention in Taizhou.
