Abstract
Few studies focused on human papillomavirus (HPV) in male patients. This study aimed to explore the detection rate and genotyping of HPV among male patients in Beijing to provide a reference for formulating prevention strategies for HPV infection. The cross-sectional study was conducted in Beijing Chaoyang Hospital from November 2015 to March 2023. It covered male patients from the urology and dermatology departments. Fifteen high-risk HPV genotypes were detected by the multiplex real-time polymerase chain reaction method. The overall detection rate of HPV was 25.19% (1288/5114, 95% confidence interval [CI] 24.00%-26.38%), of which the single infection rate was 16.99% (869/5114, 95% CI 15.97%-18.05%) and the co-infection rate was 8.19% (419/5114, 95% CI 7.46%-8.98%). The detection rate of HPV was 40.77% (521/1278), 35.58% (58/163), 32.69% (101/309), 31.91% (60/188), 12.63% (299/2367), and 32.35% (131/405) among male patients with balanitis, warts, rash, urethritis, prostatitis, and other urinary inflammation, respectively (P < 0.001). The top five HPV genotypes were HPV-52, HPV-58, HPV-16, HPV-51, and HPV-66. After the first positive HPV test, the proportion of male patients who turned negative was 22.47% within 3 months, 26.40% within 3-6 months, 24.72% within 6-12 months, 17.98% within 12-24 months, and 8.43% more than 24 months. The detection rate of HPV was high among male patients from the urology and dermatology departments in Beijing, which should be considered to develop HPV vaccines with better prevention effects.

Abstract
PURPOSE The genotype distribution of human papillomavirus (HPV) infection varies greatly in different regions. This study aims to determine the prevalence and type-specific distribution of HPV among females from Chengdu and Aba in Sichuan Province, which differ in geographical location, economic status, and living habits. These can serve as evidence of epidemic patterns for future design and implementation of vaccination and screening programs. METHODS A retrospective cross-sectional study was conducted on 144 113 women who underwent cervical screening at Chengdu Women's and Children's Central Hospital from January 2015 to September 2020. Meanwhile, 1799 samples from February 2018 to December 2021 were collected from Aba Maternal and Child Health Hospital. HPV DNA genotype testing was performed using real-time PCR. The overall prevalence, annual trend, age-specific prevalence, and type distribution were analyzed. RESULTS The overall HPV prevalence was 22.51% in Chengdu. During 2015-2020, the highest prevalence rate was observed in 2018. Age-specific HPV distribution displayed a bimodal distribution among women aged ≤25 or ≥46 years old. The top three prevalent genotypes were HPV52, -16, and -58. Although the total prevalence of HPV in Aba was 14.23%, there was an upward trend from 2018 to 2021. However, no significant differences were identified in HPV infection rate across all age groups. HPV52, -53, and -16 were the major genotypes. Furthermore, single-type HPV infections and high-risk HPV infections were identified as the most common infection types in both regions. CONCLUSION Our findings demonstrate the overall prevalence of HPV was still high in Chengdu and Aba. The age-specific prevalence distribution demonstrated different patterns. Non-vaccine-covered HR-HPV53, -51and LR-HPV81, -CP8304 were frequently detected, which was worth significant clinical attention. In summary, regional HPV screening provides valuable clinical guidance for cervical cancer prevention and vaccine selection in Western China.

Abstract
PURPOSE To determine the correlation between HPV (human papillomavirus) 52 viral load, multiple infections and ThinPrep cytology test (TCT), to inform clinical management of HPV52-positive women after cervical cancer screening. METHODS A total of 1,882 female patients who had positive quantitative HPV tests at Yuebei People's Hospital from January 2020 to December 2022, of whom 533 tested positive for HPV52. We excluded patients who combined HPV16 and/or HPV 18 positivity and whom HPV52 viral load could not be calculated. The final enrollment was 488 patients, including 400 NILM, 48 ASC-US, 28 LSIL and 12 HSIL. The HPV test is a quantitative multiplexed fluorescent PCR assay that provides both HPV genotyping and viral load. RESULTS In our study, there were differences in the median distribution of viral loads among various cytological class categories. The risk of TCT results (LSIL or worse) was increased with the increase of HPV52 viral load, for every LOG unit increase in HPV52 viral load, the risk increased by 26.6%. More importantly, we found a nonlinear relationship between HPV52 viral load and TCT results (LSIL or worse) in both single and multiple infections. When the viral load reaches a threshold, the risk of abnormal cytological results increases significantly. CONCLUSION HPV52 viral load is an independent risk factor for TCT results (LSIL or worse). The relationship between HPV52 viral load and TCT results (LSIL or worse) is not linear. Viral load may be used as a triage indicator for HPV52-positive patients, thus improving the post-screening clinical management of HPV52-positive women.

Abstract
Background Cervical cancer is primarily caused by HPV infection. The epidemiology of HPV infection in specific areas is of great meaning of guide cervical cancer screening and formulating HPV vaccination strategies. Here, we evaluated the epidemiological characteristics of HPV infection in Xiamen population. Methods In total, 159,049 cervical exfoliated cell samples collected from female outpatients in Women and Children's Hospital, School of Medicine, Xiamen between January 2013 and July 2023 were analyzed. HPV DNA detection was performed using HPV genotyping kits (Hybribio Limited Corp, China). An analysis was conducted on the prevalence of HPV infection, taking into account factors such as age, year, and multiple patterns of HPV infection. The differences in prevalence among age groups and years were compared using χ2 test. Results The overall prevalence of any 21 HPV genotypes was 18.4%, of which the high-risk HPV (HR-HPV) positive rate was 14.6%. The age-specific prevalence of HPV infection showed a bimodal distribution, with two distinct peaks, one at <25 years (31.2%) and the other at 60-64 years (32.9%). There was a downward trend in the prevalence of HPV infection over time, decreasing from 26.2% in 2013 to 14.5% in 2021, and then increasing to 19.0% in 2023. The five most prevent HR-HPV genotypes were HPV52 (4.0%), 58 (2.6%), 16 (2.5%), 51 (1.8%), and 39 (1.7%). Among the positive cases, 76.7% were detected with only one genotype and 23.3% with multiple genotypes. The most common co-infection was HPV52 + HPV58 (0.24%), followed by HPV16 + HPV52 (0.24%), HPV52 + HPV53 (0.21%), HPV52 + HPV81 (0.21%), HPV51 + HPV52 (0.19%), HPV16 + HPV58 (0.18%), and HPV39 + HPV52 (0.17%). Conclusion The study provided the largest scale information on the recent epidemiological characteristics of HPV infection in Xiamen, and even in Fujian Province, China, which would support making the prevention and control strategies for cervical cancer in the region.

HPV Infection Profiles among People Living with HIV and HPV Vaccine Acceptance among Individuals with Different HIV Infection Statuses in China: A Systematic Meta-Analysis. Vaccines (Basel) 2023; 11:1614. [PMID: 37897016 PMCID: PMC10610837 DOI: 10.3390/vaccines11101614] [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: 08/25/2023] [Revised: 09/24/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
To understand the HPV infection profiles among Chinese HIV/AIDS patients and the HPV vaccine acceptance among unvaccinated Chinese people with different HIV infection statuses after the HPV vaccine launch in China, this study searched Web of Science, PubMed, Cochrane Library, Embase, Scopus, CNKI, WANFANG, SinoMed, and VIP databases up to 23 June 2023, according to the registered protocol (CRD42023449913). A total of 58 studies were included. The results showed that the HPV infection rate among Chinese HIV/AIDS patients was 52.54% (95% CI: 42.11-62.86%) and higher in males than in females (74.55% vs. 41.04%); meanwhile, the rate was higher in the anus than in the cervix (69.22% vs. 41.71%). Although there was no statistical difference, the high-risk HPV infection rate (38.98%) was higher than low-risk HPV (23.86%), and single infections were more common (28.84%) than multiple infections (19.23%). HPV vaccine acceptance among the unvaccinated Chinese population was 59.19% (95% CI: 52.50-65.89%), and was slightly higher among HIV-infected rather than non-HIV-infected individuals (67.72% vs. 59.58%). There was a difference in acceptance among respondents from different regions. Although the difference in acceptance rate between males and females was not statistically significant (61.10% vs. 61.18%), MSM had a higher acceptance rate than non-MSM (84.28% vs. 59.05%). HPV infection is prevalent among HIV patients, demonstrating the need to increase the frequency of HPV screening for PLWH. The HPV vaccine acceptance rate is higher than that of non-HIV-infected individuals. Male acceptance is almost the same as female's, with MSM acceptance higher than non-MSM, suggesting that using MSM, especially MSM in PLWH, as an entry point may be a practical avenue to explore to further expand the scope of HPV vaccination.

Abstract
Cervical cancer, a major health concern among women worldwide, is closely linked to human papillomavirus (HPV) infection. This study explores the evolving landscape of HPV molecular epidemiology in Taiwan over a decade (2010-2020), where prophylactic HPV vaccination has been implemented since 2007. Analyzing data from 40,561 vaginal swab samples, with 42.0% testing positive for HPV, we reveal shifting trends in HPV genotype distribution and infection patterns. The 12 high-risk genotypes, in order of decreasing percentage, were HPV 52, 58, 16, 18, 51, 56, 39, 59, 33, 31, 45, and 35. The predominant genotypes were HPV 52, 58, and 16, accounting for over 70% of cases annually. The proportions of high-risk and non-high-risk HPV infections varied across age groups. High-risk infections predominated in sexually active individuals aged 30-50 and were mixed-type infections. The composition of high-risk HPV genotypes was generally stable over time; however, HPV31, 33, 39, and 51 significantly decreased over the decade. Of the strains, HPV31 and 33 are shielded by the nonavalent HPV vaccine. However, no reduction was noted for the other seven genotypes. This study offers valuable insights into the post-vaccine HPV epidemiology. Future investigations should delve into HPV vaccines' effects and their implications for cervical cancer prevention strategies. These findings underscore the need for continued surveillance and research to guide effective public health interventions targeting HPV-associated diseases.

Abstract
Background To explore the positivity rate and genotype distribution of human papillomavirus (HPV) in cervical squamous cell carcinoma (CSCC) tissues in central and eastern China and to provide theoretical basis for cervical cancer screening and prophylactic HPV vaccine development in China. Methods DNA was extracted from paraffin-embedded tissues of CSCC samples and exfoliated cervical cells of cervical cancer screening populations. 23 HPV genotypes were detected by combining polymerase chain reaction (PCR) and reverse dot hybridized gene chip detection technology in 2,306 CSCC tissues and 10,245 cervical cancer screening populations. The genotype distribution of HPV infection was analyzed. Results The overall infection rate of HPVs in 2,306 CSCC patients was 92.71%. The frequency of single-type HPV infection and multiple-type HPV infection were 86.48% and 13.51%, respectively. The most common HPV genotypes detected in Chinese CSCC tissues were HPV-16, HPV-18, HPV-31, HPV-33, HPV-45, HPV-52, HPV-58, and HPV-59. The overall positivity rate of these eight high-risk HPV (HR-HPV) genotypes in HPV-positive CSCC was as high as 96.91%. Of which the positivity rate of seven HR-HPV genotypes related to nine-valent HPV vaccines in HPV-positive CSCC was 95.09%. Meanwhile, the overall infection rates of HR-HPV and low-risk HPV (LR-HPV) in female aged 35-64 years who underwent cervical cancer screening were 13.16% and 1.32%, respectively. The high-frequency HR-HPV genotypes in cervical cancer screening women were HPV-52, HPV-58, HPV-16, HPV-53, HPV-68, HPV-39, HPV-51, and HPV-56, with positivity rates of 2.25%, 1.60%, 1.31%, 1.22%, 0.93%, 0.92%, 0.78%, and 0.74%, respectively. Conclusion Among women screened for cervical cancer in China, detecting the 8 high-frequency HR-HPV genotypes can reduce technical difficulty and reagent costs, while also improving the efficiency and effectiveness of cervical cancer screening. HPV genotyping assists gynecologists in assessing the risk of HR-HPV-positive cervical intraepithelial neoplasia and guiding them in implementing appropriate interventions. Furthermore, HPV genotyping is helpful for doctors to follow up HR-HPV-positive women and to evaluate the protective effect of HPV vaccine.

Abstract
IntroductionViral infection is an exogeneous factor for primary Sjogren’s syndrome (pSS). This study investigated the association between human papillomavirus (HPV) infections and pSS through a nationwide population based cohort study.MethodsPatients with HPV infections between January, 1999 and December, 2013 were included. The incidence of new-onset pSS in patients with HPV infections and non-HPV controls were derived. The multiple Cox regression model derived the risk of pSS in patients with HPV infections. Subgroup analysis and sensitivity analysis were performed to validate the association.ResultsDuring a follow-up period of 12 years, the adjusted hazard ratio (aHR) of pSS in patients with HPV infections was significantly higher than that in non-HPV controls (aHR=1.64, 95% CI=1.47-1.83, P<0.001). The risk of pSS increased with age and the risk increased by 2.64-fold (95% CI= 2.37-2.93) for those older than 45 years. The significant association between HPV infections and the risk of pSS persisted in the sensitivity analysis restricted in HPV infections that lasted over 12 months (aHR=1.63, 95%CI=1.45-1.83, P<0.0001). Subgroup analyses revealed that both male (aHR=1.83, 95%CI=1.47-2.28, P<0.0001) and female (aHR=1.58, 95%CI=1.40-1.79, P<0.0001) patients with HPV infections and HPV-infected patients aged between 16 and 45 years (aHR=1.60, 95%CI=1.34-1.91, P<0.0001) and over 45 years (aHR=1.67, 95%CI=1.46-1.91, P<0.0001) were associated with a significantly greater risk of pSS.ConclusionPatients with HPV infections presented with a significantly higher risk of pSS, regardless of age and sex.

Abstract
BACKGROUND Human papillomavirus (HPV) is the leading cause of cervical cancer with more than 200 genotypes. Different genotypes have different potentials in causing premalignant lesions and cervical cancers. In this study, we investigated the age-specific prevalence and genotype distribution of HPV genotypes in Northwest China. MATERIALS AND METHODS We recruited 145,918 unvaccinated women from Northwest China for population-based HPV DNA screening test during June 2015 to December 2020. And a lab-based test was performed for each volunteer by flow fluorescent technology to identify the genotypes of HPV. RESULTS The overall infection rate of HPV was 22.97%. With the participants divided into 12 groups according to age, a bimodal curve of infection rate was obtained. And the two peaks appeared in the younger than 20 group and 61-65 group, respectively. The five most common HPV genotypes included HPV 16, 58, 52, 53 and 61 in all participants, which were in descending order of frequency. Among women younger than 25 years old, HPV 6 and 11 were more common and even higher than some genotypes mentioned above. Among women older than 65 years old, HPV 18 and 66 were more common than or as high as the six most common genotypes in all populations. Additionally, the distribution of single and multiple infections in each age group was also different. CONCLUSION The baseline prevalence and genotype distribution of HPV in Northwest China was uncovered for the first time. Age was related to the epidemiology of different HPV genotypes. All the results would be of great significance for future healthcare services.

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
Background: The persistent infection of high-risk human papillomavirus (HR-HPV) is one of the most common causes of cervical cancer worldwide, and HPV type 58 (HPV58) is the third most common HPV type in eastern Asia. The E7 oncoprotein is constitutively expressed in HPV58-associated cervical cancer cells and plays a key role during tumorigenesis. This study aimed to assess the HPV58 E7 protein expression in the tissues of cervical cancer and cervical intraepithelial neoplasia (CIN). Methods: A total of 67 HPV58-positive cervical samples were collected, including 25 cervical cancer samples and 42 CIN samples. All the tissues were examined by HPV58 E7, p16INK4a and Ki67 immunohistochemistry (IHC). At last, we analyzed their association with clinical and pathological variables. Results: HPV58 E7 expression was detected in 96% of the HPV58 DNA-positive cervical cancer tissues and 85.7% of HPV58-positive CIN tissues. 65 samples of cervical cancer and CIN tissues had p16-positive staining, while 59 samples were Ki-67 positive. Conclusions: HPV58 E7 protein is highly expressed in both cervical cancer and CIN tissues. HPV58 E7 IHC could be sensitive and specific for evaluating HPV-driven cervical cancer and pre-cancerous lesions, in combination with p16 and Ki-67 IHC.

Abstract
In context of the ongoing multi-centric HPV vaccine study in India, unvaccinated married women (N = 1484) aged 18-23 years were recruited in 2012-2015 as age-matched controls to the vaccinated women and followed up yearly. We assess type-specific prevalence, natural history and potential determinants of human papillomavirus (HPV) infection in these unvaccinated women. Cervical samples were collected yearly for at least four consecutive years. A Multiplex Type-Specific E7-Based polymerase chain reaction assay was used to detect 21 HPV types. HPV prevalence was 36.4% during 6 years. Most common HPV types were 16 (6.5%) and 31 (6.1%). Highest persistence were observed for HPV 35 (62.5%) and 52 (25%). New HPV acquisition rate was 5.6/1000 person-months of observation (PMO), highest for HPV 16 (1.1/1000 PMO). Type-specific clearance rates ranged between 2.9-5.5/100 PMO. HPV 16 and/or 18 infections were 41% (95% CI 4-63%) lower among women with 2-<3 years between marriage and first cervical sample collection compared to those with <2 years. HPV prevalence and acquisition rates in young Indian women were lower than their Western counterparts. HPV 16 infections being most common shows the importance and potential impact of HPV vaccination in India. Women with 2-3 years exposure had reduced risk possibly due to higher infections clearance.

Abstract
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 < .001). Single HPV infection was the main infection category in each histopathological diagnosis, and the total infection rate was 65.83% (867/1317; P < .001). The prevalence of HPV16 or single HPV infection increased with the severity of cervical lesions (P < .001). HPV16, 58, 18, 52, and 33 may be predominant high-risk factors for cervical lesions in Henan Province. The nine-valent prophylactic HPV vaccine is more effective than a bivalent or quadrivalent vaccine for protecting women from CC in the region.

Abstract
Introduction: Cervical cancer is the most common female cancer in large areas of the developing world, and almost half of these cases (54%) arises in Asia, where cervical cancer is still threatening women's health and survival, which makes it a considerable public problem. Human papillomavirus (HPV) is one of the most powerful human carcinogens. Today, it has been proven that all cervical cancers and primary precancerous lesions are caused by carcinogenic types of HPV infections. HPV genotyping can therefore evaluate the screening programs. Methods: Five hundred fifty women referring to the gynecological centers were subjected to Pap smear cell samples. The cytopathological diagnosis of obtained cervical samples was based on the Bethesda system. HPV genotyping was carried out using the INNO-LiPA HPV Genotyping Extra II Amp assay. Results: In a total of 244 HPV positive cases, single‑type HPV infec-tion was observed in 49.6%, while multi‑type HPV infections (including ≥ 2 types) were found in 45.5% of cases. Among the 110 cases with abnormal cytology results, going-over analyses led to the identification of atypical squamous cell of unknown significance (ASCUS) in 73 cases, low‑grade squamous intraepithelial lesions (LSIL) in 24 cases, and high‑grade squamous intraepithelial lesion (HSIL) in 12 cases. In these groups, the infection rate of high-risk HPV (HR-HPV) was 89%, 82%, and 100%, respectively. Conclusion: In this study, the total population of women suffering from different cervical lesions and malignancy was found to be infected with various HPV genotypes. High prevalence of HPV- 53 and HPV- 16 detected among participants with normal cytology can be considered as a tip-off development of cervical cancer among Iranian women.

Abstract
The human papillomavirus (HPV) vaccine plays an important role in preventing a series of diseases caused by HPV. Recent studies have shown that as a primary prevention measure, it can considerably prevent HPV infection and HPV-associated cervical cancer. However, studies on the safety, efficacy, and coverage of the HPV vaccine remain insufficient, especially in developing countries. Therefore, in this review, we outlined the recent studies of the HPV vaccine in terms of immunogenicity, safety, efficacy, latest vaccination concepts, and strategies. This review may provide a theoretical basis for use of the HPV vaccine.

Virol J 2020; 17:106. [PMID: 32677948 PMCID: PMC7364514 DOI: 10.1186/s12985-020-01349-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 06/03/2020] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Long control region (LCR) of human papillomavirus (HPV) has shown multiple functions on regulating viral transcription. The variations of LCR related to different lineages/sub-lineages have been found to affect viral persistence and cervical cancer progression differently. In this study, we focused on gene polymorphism of HPV16/18/58 LCR to assess the effect variations caused on transcription factor binding sites (TFBS) and provided more data for further study of LCR in Southwest China. METHODS LCR of HPV16/18/58 were amplified and sequenced to do polymorphic and phylogenetic anlysis. Sequences of each type were aligned with the reference sequence by MEGA 6.0 to identify SNPs. Neighbor-joining phylogenetic trees were constructed using MEGA 6.0. Transcription factor binding sites were predicted by JASPAR database. RESULTS The prevalence of these three HPVs ranked as HPV16 (12.8%) > HPV58 (12.6%) > HPV18 (3.5%) in Chengdu, Southwest China. 59 SNPs were identified in HPV16-LCR, 18 of them were novel mutations. 30 SNP were found in HPV18-LCR, 8 of them were novel. 55 SNPs were detected in HPV58-LCR, 18 of them were novel. Also, an insertion (CTTGTCAGTTTC) was detected in HPV58-LCR between position 7279 and 7280. As shown in the neighbor-joining phylogenetic trees, most isolates of HPV16/18/58 were clustered into lineage A. In addition, one isolate of HPV16 was classified into lineage C and 3 isolates of HPV58 were classified as lineage B. JASPAR results suggested that TFBS were potentially influenced by 7/6 mutations on LCR of HPV16/18. The insertion and 5 mutations were shown effects in LCR of HPV58. CONCLUSION This study provides more data for understanding the relation among LCR mutations, lineages and carcinogenesis. It also helps performing further study to demonstrate biological function of LCR and find potential marker for diagnosis and therapy.

Multi-Infection Patterns and Co-infection Preference of 27 Human Papillomavirus Types Among 137,943 Gynecological Outpatients Across China. Front Oncol 2020; 10:449. [PMID: 32318343 PMCID: PMC7154087 DOI: 10.3389/fonc.2020.00449] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2019] [Accepted: 03/13/2020] [Indexed: 12/24/2022] Open
Abstract
Background: The epidemiological feature of human papillomavirus (HPV) infection is distinctive in China. We aimed to investigate the multi-infection patterns and co-infection preference of 27 HPV types among gynecological outpatients across China. Methods: Overall 137,943 gynecological outpatients were recruited from eight tertiary hospitals located in seven regions of China, between July 1st, 2014 and December 31st, 2016. The overall, region-specific, age-specific and type-specific prevalence of HPV infection were calculated, respectively. The pattern of HPV infection was also evaluated. Furthermore, rate ratio was calculated to evaluate the co-infection preference of any two HPV genotypes. Results: The overall prevalence of 27 HPVs' [17 high-risk (hr)/10 low-risk (lr)] infection was 23.5%. The age-specific HPV prevalence showed a “U-shaped” pattern. The most prevalent hrHPV genotypes were 16, 52, and 58. Multiple infections were detected in 25.8% of the HPV-positive women, in which dual infection was more prevalent. HPV 16/18 were likely to co-infected with HPV 31 but unlikely with HPV 52/58, i.e., the co-infection of HPV 16 with HPV 31 was high (3.5-fold), but low for HPV 58 (1.8-fold), and 52 (1.2-fold), while the co-infection of HPV 18 with HPV 31 was high (4.3-fold), but low for HPV 52 (1.9-fold), and 58 (1.7-fold). Conclusions: We found age-specific prevalence of HPV infection showed a “U-shaped” pattern for high and low risk HPV, suggesting the importance of screening among younger women and the necessary of detection among older women. We found a novel co-infection preference of HPV 16/18 with 31, 52, and 58, suggesting a need of developing and marketing prophylactic HPV vaccines that protect against more genotypes in China.

Abstract
Becoming armed with an appropriate strategy to isolate the minimum number of human papillomaviruses (HPV), regardless of DNA extraction method, can be a huge step in preventing false negative; it has a significant effect on the management and control of HPV infection among women's population. This study was conducted in Qom province, considering the risk factors associated with HPV. It was able to analyze genetic evolution in its genotypes and evaluated the limit of detection by a new diagnostic approach. Totally, 486 Pap smear samples were tested; then, the HPV DNA was developed by a semi-nested quantification PCR. Positive samples were sequenced and submitted to the GenBank (MG825048-MG825061). After alignment, phylogenetic and polymorphism analyses were performed on the sequenced samples with a number of GenBank sequences. The overall HPV prevalence among all women in Qom was 11.7%. HPV6 (43.24%) and HPV16 (6.75%) were the most frequent LR and HR genotypes, respectively. Although the Tajima's D of all genotypes was positive, it was negative individually. The position of genotypes 6, 11, and 73 was controversial on phylogenetic trees. Limit of detection (LOD) was obtained as about 10-100 copies per reaction in various genotypes of HPV by semi-nested qPCR. The nature of HPV could be preserved during natural selection. This research, through innovative usage of the primers, could detect different genotypes of the HPV, and inform the women society of the probable risk through its prevalence determination.

Risk of cervical dysplasia among human papillomavirus-infected women in Korea: a multicenter prospective study. J Gynecol Oncol 2019; 30:e50. [PMID: 30887765 PMCID: PMC6424843 DOI: 10.3802/jgo.2019.30.e50] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Revised: 12/15/2018] [Accepted: 01/01/2019] [Indexed: 02/07/2023] Open
Abstract
Objective Human papillomavirus (HPV) infection is the most important risk factor for cervical cancer, which progresses from precursor lesions with no symptom if left untreated. We compared the risk of cervical dysplasia among HPV-positive Korean women based on HPV types and infection patterns. Methods We observed participants of a 5-year multicenter prospective cohort study, comprising HPV-positive women with either atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion of the cervix at their enrollment. Follow-ups, comprising cytology and HPV DNA testing results, were included in the final analysis. Incidence was calculated for each infection pattern (persistent infection, incidental infection, and clearance). To investigate cervical dysplasia risk, we used Cox proportional hazard models adjusted for variables that were significantly different among infection patterns. From April 2010 to September 2017, 71 of 1,027 subjects developed cervical dysplasia more severe than high-grade squamous intraepithelial lesion of the cervix. Results Of these 71 subjects, persistent infection, incidental infection, and clearance were noted in 30, 39, and 2 individuals, respectively. Based on changes in DNA results during follow-up, cumulative incidence was 27.2%, 10.4%, and 0.5% for persistent infection, incidental infection, and clearance, respectively. Compared to clearance, the adjusted hazard ratios for cervical dysplasia were 51.6 and 24.1 for persistent and incidental infections, respectively (p<0.001). Conclusion Individuals persistently infected with the same HPV types during the follow-up period had the highest risk of severe cervical dysplasia. Hence, it is necessary to monitor HPV types and infection patterns to prevent severe cervical precancerous lesions.

Abstract
Cervical cancer is by far the most common HPV-related disease. About 99.7% of cervical cancer cases are caused by persistent genital high-risk human papillomavirus (HPV) infection. Worldwide, cervical cancer is one of the most common cancer in women with an estimated 528,000 new cases reported in 2012. Most HPV infections clear spontaneously but persistent infection with the oncogenic or high-risk types may cause cancer of the oropharynx and anogenital regions. The virus usually infects the mucocutaneous epithelium and produces viral particles in matured epithelial cells and then causes a disruption in normal cell-cycle control and the promotion of uncontrolled cell division leading to the accumulation of genetic damage. There are currently two effective prophylactic vaccines against HPV infection, and these comprise of HPV types 16 and 18, and HPV types 6, 11, 16 and 18 virus-like particles. HPV testing in the secondary prevention of cervical cancer is clinically valuable in triaging low-grade cytological abnormalities and is also more sensitive than cytology as a primary screening. If these prevention strategies can be implemented in both developed and developing countries, many thousands of lives could be saved.

Abstract
Neuroendocrine cervical cancer is a rare subtype of cervical cancer with a highly aggressive malignancy. This study was conducted to analyse the human papillomavirus (HPV) infection and molecular abnormalities in Vietnamese neuroendocrine carcinomas of the uterine cervix. HPV genotyping and p53 mutations were examined using polymerase chain reaction (PCR)-based direct sequencing. Mutations of epidermal growth factor receptor (EGFR), Kirsten rat sarcoma (KRAS), neuroblastoma RAS viral oncogene homolog (NRAS) and v-Raf murine sarcoma viral oncogene homolog B (BRAF) were identified using commercial kits. Four high-risk HPV genotypes were identified in 26 (86.7%) out of a total of 30 tumours. The prevalence of HPV 16, 18, 31 and 45 was 20.0%, 50.0%, 20.0% and 36.7%, respectively. Overexpression of p16INK4a was observed in 93.3% of cases and was significantly correlated with high-risk HPV infections. Furthermore, p53 and NRAS mutations were detected in five (16.7%) and one (3.3%) cases, respectively, whereas no EGFR, KRAS or BRAF mutations were observed. These results demonstrate that high-risk HPV infection may be an important oncogenic factor for the development and progression of cervical neuroendocrine carcinoma.

Abstract
Accumulating evidence indicates that persistent infection with high-risk oncogenic human papillomavirus (HPV) genotypes is the most important risk factor for cervical cancer, and that the distribution of HPV genotypes varies regionally. This study explored the prevalence and genotype distribution of HPV infection among Han, Yi, and Bai women in various regions of Dali Bai Autonomous Prefecture, Yunnan Province, China. This cross-sectional study included 2779 women (20-76 years old) who were referred for 21-HPV genotype array diagnostic from five regions of Dali Bai Autonomous Prefecture between February 2013 and May 2016. Statistical methods used included a the χ2 test, Fisher's exact test, t test, and logistic regression. Overall HPV prevalence in the study population was 7.6%. HPV-52, HPV-58, HPV-18, HPV-81, and HPV-16 were the most prevalent genotypes in the study area, and notably, the prevalence of HPV-58 was significantly higher among women in Heqing County than that in other regions. Univariate analysis showed that husband's age, region, fertility status, and parity were potential factors associated with HPV infection. Multivariate logistic regression analysis revealed that Heqing County was an independent risk factor for HPV infection among women in the Dali area, moreover, Yi women showed the highest risk for HPV infections. Overall, our finding emphasizing the urgent need for an HPV screening and prevention program in Heqing County and Yi women. We also suggest that HPV-related health education should be provided not only to women, but also to men, to reduce the risk of infection in women.

Abstract
Objective To evaluate the risk of genotype-specific human papillomavirus (HPV) infections for the spectrum of cervical carcinogenesis and the distribution of HPV types according to age and different cervical lesions Methods This study included HPV-positive women who underwent cervical biopsy at the Cheil General Hospital & Women's Healthcare Center between July 1, 2011 and December 31, 2017. HPV genotyping was conducted using a Cheil HPV DNA chip kit. Results The study sample consisted of 400 normal, 399 cervical intraepithelial neoplasia (CIN) 1, 400 CIN 2, 400 CIN 3, and 389 cervical cancer cases. HPV 16 was the most common type found with a prevalence of 9.5% in normal, 6.8% in CIN 1, 15.0% in CIN 2, 44.5% in CIN 3, and 64.3% in cervical cancer. The most common HPV types were 16, 52, 58, 53, 51, 56, 68, and 18 in all study samples. HPV 16, 31, 33, and 58 were more common in CIN 2/3 and cancer, and HPV 39, 51, 53, 56, 66, and 68 were more common in CIN 1 and normal cases (p<0.001). In CIN 3 and cervical cancer, HPV 16 was the most common type in all age groups. HPV 52 was the most common type in CIN 2 (all age groups) and in CIN 1/normal (age ≤30 years) cases. Among the high-risk HPV types, 16, 31, 33, 52, and 58 showed significant risk for high-grade disease. Conclusions HPV 16, 31, 33, 52, and 58 showed the significant risk of high-grade disease for cervical carcinogenesis.

Antigenic Peptide Prediction From E6 and E7 Oncoproteins of HPV Types 16 and 18 for Therapeutic Vaccine Design Using Immunoinformatics and MD Simulation Analysis. Front Immunol 2018; 9:3000. [PMID: 30619353 PMCID: PMC6305797 DOI: 10.3389/fimmu.2018.03000] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2018] [Accepted: 12/04/2018] [Indexed: 12/31/2022] Open
Abstract
Human papillomavirus (HPV) induced cervical cancer is the second most common cause of death, after breast cancer, in females. Three prophylactic vaccines by Merck Sharp & Dohme (MSD) and GlaxoSmithKline (GSK) have been confirmed to prevent high-risk HPV strains but these vaccines have been shown to be effective only in girls who have not been exposed to HPV previously. The constitutively expressed HPV oncoproteins E6 and E7 are usually used as target antigens for HPV therapeutic vaccines. These early (E) proteins are involved, for example, in maintaining the malignant phenotype of the cells. In this study, we predicted antigenic peptides of HPV types 16 and 18, encoded by E6 and E7 genes, using an immunoinformatics approach. To further evaluate the immunogenic potential of the predicted peptides, we studied their ability to bind to class I major histocompatibility complex (MHC-I) molecules in a computational docking study that was supported by molecular dynamics (MD) simulations and estimation of the free energies of binding of the peptides at the MHC-I binding cleft. Some of the predicted peptides exhibited comparable binding free energies and/or pattern of binding to experimentally verified MHC-I-binding epitopes that we used as references in MD simulations. Such peptides with good predicted affinity may serve as candidate epitopes for the development of therapeutic HPV peptide vaccines.

Prevalence characteristics of single and multiple HPV infections in women with cervical cancer and precancerous lesions in Beijing, China. J Med Virol 2018; 91:473-481. [PMID: 30281807 DOI: 10.1002/jmv.25331] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Accepted: 09/29/2018] [Indexed: 11/09/2022]
Abstract
We assessed the prevalence characteristics of single and multiple high-risk human papillomavirus (HR-HPV) infections. A total of 1783 women who underwent colposcopy and cervical biopsy for abnormal ThinPrep Cytology Test and/or HR-HPV subtype genotyping results were enrolled in the study. Among the participants, 770 were diagnosed with cervicitis, 395 with cervical intraepithelial neoplasia grade 1 (CIN1), 542 with CIN2-3, and 76 with squamous cell carcinoma (SCC), with HR-HPV infection rates of 75.8%, 85.8%, 95.9%, and 88.4%, respectively. The prevalence of total and multiple HR-HPV infections exhibited a bimodal age distribution with a peak at ≤25 years, a decline with age and a second peak at ≥55 years, whereas single HR-HPV infections exhibited one peak from 35 to 44 years. The four most dominant HPV genotypes were HPV 16 (29.5%), 52 (15.0%), 58 (14.2%), and 18 (10.4%). In total, 67.0%, 70.4%, and 82.1% of patients with CIN1, CIN2-3, and SCC, respectively, had a single HR-HPV infection, which increased significantly with the aggravation of the cervical lesion grade (P = 0.045). Patients with a single HPV 16 infection had higher incidences of CIN2+ (62.2%) than those with multiple HPV 16 infections (52.4%) (P = 0.021). Patients coinfected with HPV 16 had higher CIN2+ incidence than those with single HPV 52, 31, 33, 35, 39, 45, 51, 56, or 59 infections (P < 0.001). This study provided baseline data on the prevalence characteristics of single and multiple HR-HPV infections in women attending a gynecological outpatient clinic in Beijing.

Abstract
The distribution of human papillomaviruses (HPVs) must be understood for the control and prevention of cervical cancer. Community-based Papanicolaou and HPV DNA tests were performed on 41 578 women. The prevalences of HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 were assessed. In total, 10% women were infected/co-infected by these HPVs. The infection rate increased from 7.1% in women aged ⩽30 years to 10.4% in those aged 50–60 years, and then decreased slightly to 9.9% in those aged >60 years. The HPV 16 and 58 positivity rates were significantly higher among women with high-grade squamous intraepithelial lesions (HSILs) than among those with cervicitis/negativity for intraepithelial lesion or malignancy (NILM) or low-grade SILs (LSILs). The HPV 18, 52 and 68 infection rates were significantly lower in women with HSILs than in those with NILM or LSILs. The proportion of women infected by multiple HPV strains was higher among those with HSILs. The proportions of the five most common genotypes, HPV 16, 18, 33, 52 and 58, increased with the number of co-infecting strains. HPV 16 and 58 were the high-risk HPVs in the Shanghai community and should be the focus in HPV screening and vaccination.

Abstract
To date, empirical studies on HPV vaccine uptake are still limited in Chinese populations and mainly conducted in female cohorts. In order to inform health services planning and health promotion programmes for HPV vaccination, this cross-sectional study aimed to report the prevalence of self-reported HPV vaccination status and to examine gender and sexual orientation differences in the uptake of HPV vaccine in Chinese college students. The overall prevalence of HPV vaccine uptake was 27.6% (n = 242), with a significantly higher prevalence in females (39.7%) than in males (4.7%). 91.4% of subjects heard about HPV vaccination, with a significantly higher prevalence in females (93.8%) than in males (86.8%). The prevalence of HPV vaccine uptake was only 2.6% for bisexual/ homosexual males and 5.0% for heterosexual males. Only 45.8% of the overall subjects knew HPV vaccination is not for females only, with a significantly higher prevalence in females (49.7%) than in males (38.6%). The low prevalence of male HPV vaccine uptake and awareness called for the need to have more male-specific HPV campaigns to promote HPV vaccination awareness and uptake in males to reduce the overall prevalence of HPV infection.

Abstract
Background: Cervical cancer caused by human papilloma virus (HPV), is the second most common cancer for women. This cancer is distributed worldwide, with ~80% of cases are found in the developing countries. In Indonesia, data of HPV genotypes are still limited and do not represent all regions of the country. Thus, here we report genotyping of HPV samples collected from the Dr. Soetomo Hospital Surabaya Indonesia patients, in 2013. Materials and Method: A cross sectional study was performed using 68 paraffin blocks of low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and squamous cell carcinoma (SCC) cervix. Result: This study showed that HPV genotypes found in LSIL samples are HPV 16, 18, 6/33 or 68/72. Furthermore, those in HSIL are HPV 16, 18, 52, 59, 67, 6/18, 6/45, 16/67, 26/61, or 52/67, while in SCC are HPV 16, 18, 45, 52, 56, 16/18 or 16/45. Single-genotype infection, i.e. by HPV 16, 18, 45, 52, 56, 59, or 67, was observed in 86.77% (59/68) of samples, whereas multiple-genotype infections, i.e. by HPV 6/18, 6/33, 6/45, 16/18, 16/45, 16/67, 26/61, 52/67, or 68/72, was found in 13.23% (9/68) of the samples. Conclutions: The mostly HPV genotype identified in this study is HPV 16 (62.68%), then followed by HPV 18 (20.9%), HPV 45 (5.97%), 52 (5.97%), and 67 (4.48%). HPV 16 and 18 have used as vaccine, and HPV 45 has cross reaction with HPV 18, then HPV 52 and 67 should be considered as the second-generation HPV vaccines.

Abstract
Human papillomavirus (HPV) type 31 is an important pathogenic subtype associated with cervical cancer. The aims of the present study were to analyze E5, E6, E7 and L1 gene mutations of HPV‑31 among females, and to elucidate the evolutionary associations between them. In total, 87 positive samples were collected. The E5, E6, E7 and L1 genes were amplified by polymerase chain reaction and sequenced. Subsequently, two phylogenetic trees were constructed from the nucleotide sequences of the E5, E6 and E7 and the L1 variants of HPV‑31. In total, 31 mutation sites of E5, E6 and E7 genes were identified, of which 16 were non‑synonymous. T4053A (F80I), C285T (H60Y), C520T (A138V) and A743G (K62E) were the most common non‑synonymous mutations. A total of 30 mutation sites of L1 genes were identified, of which four were non‑synonymous. The most common non‑synonymous mutations of L1 genes were A6350G (T29A) and C6372A (T36N). By phylogenetic analysis, A and C variants were most frequently detected, while B variants were less frequently detected in this population. The sequence variation data obtained in the present study provides a foundation for future research regarding HPV‑induced oncogenesis, and may prove valuable for developing diagnostic probes and in the design of HPV vaccines for targeted populations.

Abstract
Objective To explore the genotype distribution of high-risk human papillomavirus (HR-HPV) and its attribution to different grades of cervical lesions in rural China, which will contribute to type-specific HPV screening tests and the development of new polyvalent HPV vaccines among the Chinese population. Methods One thousand two hundred ninety-two subjects were followed based on the Shanxi Province Cervical Cancer Screening Study I (SPOCCS-I), and screened by HPV DNA testing (hybrid capture® 2 [HC2]), liquid-based cytology (LBC), and if necessary, directed or random colposcopy-guided quadrant biopsies. HPV genotyping with linear inverse probe hybridization (SPF10-PCR-LiPA) was performed in HC2 positive specimens. Attribution of specific HR-HPV type to different grades of cervical lesions was estimated using a fractional contribution approach. Results After excluding incomplete data, 1,274 women were included in the final statistical analysis. Fifteen point two percent (194/1,274) of women were HR-HPV positive for any of 13 HR-HPV types (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68) and the most common HR-HPV types were HPV16 (19.1%) and HPV52 (16.5%). The genotypes most frequently detected in HR-HPV-positive cervical intraepithelial neoplasia grade 1 (CIN1) were HPV52 (24.1%), HPV31 (20.7%), HPV16 (13.8%), HPV33 (13.8%), HPV39 (10.3%), and HPV56 (10.3%); in HR-HPV-positive cervical intraepithelial neoplasia grade 2 or worse (CIN2+): HPV16 (53.1%), HPV58 (15.6%), HPV33 (12.5%), HPV51 (9.4%), and HPV52 (6.3%). HPV52, 31, 16, 33, 39, and 56 together contributed to 89.7% of HR-HPV-positive CIN1, and HPV16, 33, 58, 51, and 52 together contributed to 87.5% of CIN2+. Conclusion In summary, we found substantial differences in prevalence and attribution of CINs between different oncogenic HPV types in a rural Chinese population, especially for HPV16, 31, 33, 52, and 58. These differences may be relevant for both clinical management and the design of preventive strategies.

Abstract
OBJECTIVE To understand the experiences and perceptions of having cervical cancer screening tests and to explore the extant barriers to having the tests among first-generation Chinese American women in the United States. DESIGN Qualitative, descriptive, phenomenological research. SETTING Los Angeles, California. PARTICIPANTS Snowball and purposive sampling of 12 Chinese American immigrant women ages 20 to 65 years. METHODS Individual face-to-face, in-depth, semistructured interviews in which participants were asked about their experiences and perceptions about cervical cancer screening. Interviews were audiotaped, transcribed, and translated into English. Data analysis included comparing and distinguishing, collecting and counting, and presupposing and inferring. RESULTS Through the analysis process, we identified four major themes that reflected the experiences, perceptions, and barriers to having cervical cancer screening among Chinese American women: Belief in a Healthy Lifestyle, Maintaining Privacy for Female Health Problems, Fear of Losing Control, and Feeling Vulnerable in an Unfamiliar Health Care System. These themes indicated that Chinese immigrant women in the United States face challenges to their cultural health beliefs and practices with regard to decision-making and health-seeking behaviors related to cervical cancer screening. They felt more vulnerable as immigrants because of systematic barriers to navigation of the unfamiliar health care system and limited resources. CONCLUSION Women's health care providers should be aware of and give consideration to cultural differences through the provision of more educational information and comfort to Chinese immigrant women who seek cervical cancer screening. Ultimately, the development of culturally appropriate and affordable cancer prevention programs with effective strategies is important to ease Chinese American women's senses of vulnerability.

Abstract
HPV infected cervical cells secrete mediators that are gradually changed and have influence on infiltrating M2 phenotypic monocytes in cervical lesions. However, profiles of circulating immune cells in women with cervical lesions and M2 phenotypic monocyte activity in HPV infected cervical lesions are limited. This study aimed to investigate circulating monocyte populations correlated with M2 phenotype density and its activity in HPV infected cervical lesions. HPV DNA was investigated in cervical tissues using PCR. High risk HPV E6/E7 mRNA was detected using in situ hybridization. CD163 immunohistochemical staining was performed for M2 macrophage. CD163 and Arg1 mRNA expression were detected using real-time PCR. Circulating monocyte subpopulations were analyzed using flow cytometry. CD163 and Arg1 mRNA expression were increased according to cervical lesion severity and corresponding with density of M2 macrophage in HSIL and SCC in stroma and peri-tumoral areas. Additionally, the relationship between M2 macrophage infiltration and high risk HPV E6/E7 mRNA expression was found and corresponded with cervical lesion severity. Circulating CD14+CD16+ and CD14+CD163+ monocytes were elevated in No-SIL and cervical lesions. Interestingly, CD14+CD64+ monocyte was greatly elevated in HSIL and SCC, whereas intracellular IL-10+ monocytes were not significantly different between cervical lesions. The correlation between increasing ratio of circulating CD64+/CD163+ monocyte and density of infiltrating CD163+ monocytes was associated with severity of HPV infected cervical lesions. The elevated circulating CD64+/CD163+ monocyte ratio correlates to severity of HPV infected cervical lesions and might be a prognostic marker in cervical cancer progression.

Human papillomavirus genotype distribution among HPV-positive women in Sichuan province, Southwest China. Arch Virol 2017; 163:65-72. [PMID: 28983744 DOI: 10.1007/s00705-017-3556-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2017] [Accepted: 08/30/2017] [Indexed: 01/05/2023]
Abstract
In this hospital-based descriptive study, the genotype distribution of human papillomavirus (HPV) among HPV-infected women were investigated in 4,305 gynecological patients in Sichuan province. Females attending gynecology clinics between March 2014 and March 2015 were subjected to HPV screening after giving informed consent. Cervical scrapings were examined by cytopathology and colposcopy-directed biopsies. HPV genotyping was performed on a Luminex 200 system. Seventeen high-risk (HR) genotypes (HPV-16, -18, -31, -33, -35, -39, -45, -51, -52, -53, -56, -58, -59, -66, -68, -73, and -82) and seven low-risk (LR) genotypes (HPV-6, -11, -42, -43, -61, -81, and -83) were detected. Among all HPV-positive women, 34.1% (1,467/4,305) of the cases showed abnormal cytology and biopsy, including high-grade squamous lesions (HSIL), cervical intraepithelial neoplasias of grades 2 and 3 (CIN2/CIN3), and cervical cancer (CC). HPV-16, -52, and -58 were the predominant genotypes, followed by HPV-56, -18, -59, -39, -53, -33, and -81. A total of 3,785 (87.9%) HPV positive women were found to have HR HPV infection, while 859 (20.0%) were found to have LR HPV infection. Among all patients, 79% (3,401/4,305) were infected with a single strain of HPV, 85.5% (2,907/3,401) cases of which were of the HR HPV genotype. In cervical precancerous lesions (CPLs) and CC patients, HR HPV-16, -58, -52, -33, and -18 were the predominant genotypes. Interestingly, 33 CPL patients had a single LR HPV infection with HPV-61, -11, -81, -6, -43, or -42. Furthermore, one CC patient was infected only with LR HPV-11. According to the abundant genotype diversity of HPV in Sichuan, we suggest that a large-scale epidemiological investigation should be launched, not only to understand the distribution of HPV genotype, but also to provide information needed for HPV vaccination programs and to predict the effectiveness of current vaccines in Southwest China.

Abstract
Aim: The present study aimed to investigate the effect of codon optimization on E6 recombinant protein production in Lactococcus lactis. Method: Here we define the construction of shuttle vector harboring wild-type and codon-optimized HPV16 E6 oncogene, with maximum number of infrequent codons exchanged with codons that are frequently used in Lactococcus lactis subsp. cremoris MG1363. Results: Hence, the codons encoding 159 amino acids were modified, in which a total of 91 codons were changed, resulting in approximately threefold increase in protein expression of recombinant E6 (rE6). Conclusion: Our data revealed that codon usage optimization according to L. lactis desired codon usage can dramatically increase the expression of HPV16 E6, suggesting that this strategy is a valuable approach for immunization through DNA vaccine.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is the main etiological factor for the development of cervical cancer. Here we assessed the prevalence and distribution of HPV genotypes in Fujian population. METHODS A total of 8678 women aging from 17 to 84 years olds were recruited from the Fujian Medical University Union Hospital in Fujian Province. Every woman had a face-to-face interview. Cervical samples were collected from each participant and HPV screening was conducted using microarray hybridization. RESULTS Our study showed that the HPV prevalence in Fujian province was 38.3%. Among the positive individuals, 70.6% were detected for single HPV infection, 29.4% for multiple HPV infections. Further analysis showed that the prevalence of HPV infection significantly increased from 2009 to 2015. The four most common high risk human papillomavirus (HR-HPV) genotypes were HPV16 (8.5%), HPV52 (7.9%), HPV58 (6.2%), HPV 53 (3.5%), collectively accounting for 60.5% of all detected HPV infection. Age subgroup analysis showed two peaks for the frequencies of overall and multiple HPV infections, one for the group of women under 25 years old, and the other for the group over 55 years old. CONCLUSIONS HPV infection is becoming serious in Fujian province, which indicates the imperative to implement a HPV vaccination and screening program for this region.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccines have been shown to be effective for the eradication of HPV and prevention of cervical cancer. However, the number of women who receive HPV vaccinations has decreased over the last several years in Japan, due to concerns about adverse reactions associated with the vaccines. We evaluated the safety of three types of HPV vaccines separately in young women and the difference in the risk of adverse reactions between HPV and other vaccines by conducting a meta-analysis. METHODS Primary literature was retrieved from MEDLINE, the Cochrane Central Register of Controlled Trials, and Japana Centra Revuo Medicina. Prospective controlled studies with participants consisting exclusively of healthy women who received bivalent, quadrivalent, or 9-valent HPV (2vHPV, 4vHPV or 9vHPV) vaccines were included. Primary safety outcome was the incidence of solicited local and systemic symptoms, and unsolicited symptoms. When two or more studies were found for the same analysis, a meta-analysis was applied. RESULTS A total of 24 controlled studies from 22 articles were included in our study. Of the 24 studies, 16 were placebo-controlled and eight were active-controlled (different HPV vaccine or hepatitis vaccine). Average ages of the participants ranged from 12 to 37 years. A significantly higher incidence of solicited local symptoms was observed following injection of HPV vaccines (2vHPV and 4vHPV) compared to placebo, but there was no difference between HPV vaccines [risk ratio (RR) for 2vHPV: 1.25, 95% confidence interval (CI): 1.09 to 1.43, RR for 4vHPV: 1.16, 95% CI: 1.11 to 1.20]. The incidence of solicited systemic symptoms was not different between HPV vaccines and placebo (RR: 1.04, 95% CI: 0.99 to 1.09). The incidence of unsolicited symptoms was significantly higher for 2vHPV vaccine compared to placebo (RR: 1.28, 95% CI: 1.01 to 1.63), but was not significantly different between 2vHPV and hepatitis B vaccines. CONCLUSIONS HPV vaccines had significantly higher risk of any injection site symptom compared to placebo or other vaccines (hepatitis A and B vaccines), and the incidence of solicited local symptoms was no difference between 2vHPV vaccination and 4vHPV vaccination. However, the most adverse reactions were transient.

Abstract
This study was designed to explore baseline data about the prevalence and distribution of human papillomavirus (HPV) genotypes among Chinese women who had cervical intraepithelial lesions and cervical cancer. A total of 511 patients were recruited, and biopsy samples were collected from these patients. Polymerase chain reaction was used to detect HPV-positive samples, and the HPV GenoArray kit was used for genotyping. A total of 23 genotypes were detected, including 13 that were high risk-HPV (HR-HPV), 3 that were potential high risk-HPV (PHR-HPV) and 7 that were low risk-HPV (LR-HPV). The prevalence rates of HPV infection in Han women diagnosed with cervical intraepithelial lesions (CIN) 1, 2, and 3 and squamous cell carcinoma (SCC) were 98.30%, 97.56, 100% and 90%, respectively. The HPV-positive cases in women of other ethnicities diagnosed with CIN1, CIN2, and CIN3 and SCC were 95%, 90.91%, 88.23% and 83.33%, respectively. The most frequent genotypes in both ethnic groups were HPV-16, 52, and 58. LR-HPV was detected in SCC lesions in the non-Han ethnic group. In the Han ethnic group, the LR-HPV genotype was mostly restricted to CIN1 lesions. Furthermore, we found a high prevalence of PHR-HPV-81 in SCC lesions among Han women. Ethnic background, smoking, sex at an early age, unprotected sex, use of contraceptives, and the withdrawal method were found to be significantly associated with HPV infection. In conclusion, this study explores epidemiological data regarding the prevalence of HPV and the genotype distribution in patients with SCC and CIN lesions in Yunnan Province, China.

J Cancer 2017; 8:1263-1270.

Abstract
The prevalence of infection by different genotypes of human papillomavirus (HPV) varies among different geographic areas. We studied the prevalence of infection by 21 HPV genotypes in cervical tissue specimens from 4213 women in the Guiyang district, that is located in the southwest of China and is dominated by minor ethnicities of Chinese, and 2074 cases in our cohort had pathological diagnosis available. The overall infection rate was 36.98%. Most (72.08%) infectors were positive for only one HPV subtype, with the remaining being cases infected by two or more subtypes. Infections by the HPV subtypes 16, 52 and 58 were the most prevalent, having rates of 34.66%, 16.03%% and 15.53%, respectively. The most common cervical lesions in HPV infections were genital warts, cervical cancer (CC) and cervical intraepithelial neoplasia (CIN). Age and age at first sexual activity were independent risk factors for HPV infections that in turn cause certain cervical lesions. Intriguingly, while 94.90% of the CC patients were infected by oncogenically high-risk (HR) HPV subtypes, only 2.75% and 2.29% of these patients were infected by oncogenically low-risk (LR) subtypes or other-subtypes with their oncogenicity unclear. The rates of infection by LR-HPVs and other-HPVs were also low, being 4.63% and 6.76%, respectively, in the patients with CIN that is a precursor lesion of CC, lower than the 8.54% and 18.20%, respectively, in the women without a cervical lesion. Our data provides an important foundation for prevention, diagnosis and treatment of HPV infection in Guiyang district and suggests that development of vaccines for prevention and treatment of CC in this area should first target the HPV subtypes 16, 52 and 58, but not subtype 18 as for many other places. It deserves study whether infections by certain LR-HPVs and other-HPVs may serve as attenuated live vaccines for prevention of CC.

Abstract
BACKGROUND The mortality of cervical cancer in Longnan is as high as 39/10 million, ranking first in China. METHODS Between 2012 to 2016, 329 samples with cervicitis, cervical intraepithelial neoplasia grade 1 to 3 (CINI to III), and invasive squamous cell carcinoma (SCC) were collected. HPV genotypes were examined with a validated kit for 23 different HPV subtypes. RESULTS Compared to cervicitis, the HPV positivity is significantly higher in CINI, CIN II/III, and SCC (38.60%, 74.60%, 87.50% and 89.05%, P < 0.001) and the positivity is also higher in SCC compared to CINI (P < 0.01). The most frequently detected genotypes were HPV16 in cervicitis, HPV16, 58 and 52 in CINI and CIN II/III, and HPV16, 58 and 18 in SCC groups. HPV16 positivity in cervicitis, CINI, CIN II/III, and SCC patients were 45.46%, 46.81%, 60.32% and 78.69%, respectively. Compared to cervicitis and CINI, the odds ratios (OR) for SCC in HPV16 positive patients were 2.96 (95% confidence interval [CI]: 1.09-8.00, P < 0.05) and 4.20 (95% confidence interval [CI]: 2.05-8.61, P < 0.001), respectively. In addition, the multiple infections in cervicitis, CINI, CINII/III and SCC group are 9.09%, 27.66%, 26.98% and 25.41% and HPV16 + 58 was the most common combinations. CONCLUSION These findings highlight the key role of HPV16, 58, 52 and 18 in the development of CIN and SCC in Longnan women and a fully aware of regional differences in HPV genotype distribution are tasks for cervical cancer control and prevention.

Abstract
The persistent infection of high-risk human papillomavirus (HPV) is one of the most common causes of cervical cancer worldwide, and HPV type 58 is the third most common HPV type in eastern Asia. The E7 oncoprotein is constitutively expressed in HPV58-associated cervical cancer cells and plays a key role during tumorigenesis. To study the biological function of HPV58 E7 and to characterize E7 protein-host cell interactions, we cloned the human HPV58 E7 gene and produced specific E7 antibodies. The HPV58 E7 gene was cloned into a prokaryotic expression vector, pGEX-4T2. The recombinant plasmid pGEX-4T2-(HPV58-E7) was transformed into Escherichia coli DH5α and expressed as a fusion protein containing a GST tag. After purification and removal of the GST affinity tag, the E7 protein was used as an antigen for the production of antiserum in rabbits. The specificity of the purified HPV58 E7 antibody was detected by western blotting, immunofluorescence and immunohistochemistry analysis. These methods demonstrated that the polyclonal antibody could specifically recognize the endogenous and the recombinant HPV58 E7 proteins. Immunohistochemistry analysis indicated that the E7 protein was localized in the nucleus of cervical cancer cells.

Abstract
Background The integration of human papilloma virus (HPV) into host genome is one of the critical steps that lead to the progression of precancerous lesion into cancer. However, the mechanisms and consequences of such integration events are poorly understood. This study aims to explore those questions by studying high risk HPV16 integration in women with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (SCC). Methods Specifically, HPV integration status of 13 HPV16-infected patients were investigated by ligation-mediated PCR (DIPS-PCR) followed by DNA sequencing. Results In total, 8 HPV16 integration sites were identified inside or around genes associated with cancer development. In particular, the well-studied tumor suppressor genes SCAI was found to be integrated by HPV16, which would likely disrupt its expression and therefore facilitate the migration of tumor. On top of that, we observed several cases of chromosome translocation events coincide with HPV integration, which suggests the existence of chromosome instability. Additionally, short overlapping sequences were observed between viral derived and host derived fragments in viral-cellular junctions, indicating that integration was mediated by micro homology-mediated DNA repair pathway. Conclusions Overall, our study suggests a model in which HPV16 might contribute to oncogenesis not only by disrupting tumor suppressor genes, but also by inducing chromosome instability.

Abstract
INTRODUCTION In this study we aimed to determine the overall and type-specific prevalence of cervical human papillomavirus (HPV) infection and risk factors for such infection among women in rural Nepal, and to investigate the distribution of HPV infection by cervical cytology. MATERIAL AND METHODS The study was conducted among women aged ≥15 years in five rural villages within Kavre District in Nepal. Sociodemographic data and information on risk factors for cervical cancer were obtained through an interview, and a cervical specimen was collected for HPV DNA detection and typing using the Anyplex™ ll HPV28 Detection system, and for Papanicolaou test. RESULTS Among the 1289 women in whom a valid HPV result was obtained the median age was 40 years (range 17-86 years). Overall, the HPV prevalence was 14.4%, 7.9% for high-risk and 6.5% for low-risk HPV types, and was similar between age groups. The five most common HR types were HPV-18 (2.3%), HPV-51 (1.2%), HPV-59 (1.1%), HPV-31 (0.9%), and HPV-16 (0.8%). The prevalence of high-risk types in women with and without abnormal cytology was 8.3 and 7.7%, respectively. HPV infection was associated with current smoking, formal education, and being married to a husband with at least one previous marriage. CONCLUSIONS This is the first population-based study to report the prevalence of a broad range of HPV types among women from rural Nepal. These data are crucial for development of preventive strategies to reduce cervical cancer burden in the country.

Abstract
A multi-center study was conducted to examine 6,628 eligible Japanese women aged from 16 to 50 years for uterine cervical abnormality and HPV infection with a liquid based-cytology test and a novel HPV test using the PCR-SSOP-Luminex(®) method identifying 31 HPV genotypes. In 3,047 normal subjects, the overall prevalence across all HPV types was 25%, while that of the common 13 high-risk (Common-13HR) types (HPV-16, 18. 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68) was 17%, and that of the definite high-risk (Definite-HR) types (HPV-16, 18. 31, 33, 35, 45, 52, and 58) was 12%. For Definite-HR, HPV-52, 16, and 58 were the most common, HPV-31 was relatively common, and HPV-18 was less common, while HPV-33, 35, and 45 were rare. Seven Definite-HR excluding HPV-45 and seven Possible-HR (HPV-39, 51, 56, 66, 68, 70, and 82) HPV types were identified as a single type infection in patients with high-grade squamous intraepithelial lesion (HSIL) or worse. The Common-13HR types were detected in 89% of subjects with HSIL, whereas either Definite-HR or Possible-HR types were detected in 95% of HSIL. These 1420 HPV types appear to be involved with HSIL or worse in Japan. The prevalences of multiple-type HPV infections were identified in roughly half of HPV-positive subjects, and decreased significantly with age in normal population and abnormal cytology groups, although the prevalences of single-type infections increased with age in the latter group. Most HPV infections are cleared for some years, while a certain HR-HPV type persists to induce HSIL.
