Global evaluation of lineage-specific human papillomavirus capsid antigenicity using antibodies elicited by natural infection. Nat Commun 2024; 15:1608. [PMID: 38383518 PMCID: PMC10881982 DOI: 10.1038/s41467-024-45807-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 02/05/2024] [Indexed: 02/23/2024] Open
Abstract
Human Papillomavirus (HPV) type variants have been classified into lineages and sublineages based upon their whole genome sequence. Here we have examined the specificity of antibodies generated following natural infection with lineage variants of oncogenic types (HPV16, 18, 31, 33, 45, 52 and 58) by testing serum samples assembled from existing archives from women residing in Africa, The Americas, Asia or Europe against representative lineage-specific pseudoviruses for each genotype. We have subjected the resulting neutralizing antibody data to antigenic clustering methods and created relational antigenic profiles for each genotype to inform the delineation of lineage-specific serotypes. For most genotypes, there was evidence of differential recognition of lineage-specific antigens and in some cases of a sufficient magnitude to suggest that some lineages should be considered antigenically distinct within their respective genotypes. These data provide compelling evidence for a degree of lineage specificity within the humoral immune response following natural infection with oncogenic HPV.

Abstract
OBJECTIVES Studies already pointed out the increased risk of human papillomavirus (HPV) positivity and the implied risk of cervical dysplasia and even cervical carcinoma in pregnant women with human immunodeficiency virus (HIV) infection. Nevertheless, due to less data there is still no standardised and expanded screening for this high-risk group. CONTENT Two online databases (PubMed, EMBASE) were used to identify eligible studies. Results are shown in percentages. Wherever useful the arithmetic mean was calculated. SUMMARY Seven studies were included. Pregnant WLWH showed HPV prevalence between 34 and 98.4 %. Different sensitivity and specificity among PCR methods for HPV detection could be a reason for the large range concerning HPV prevalence. Risk factors like Age, Smoking, Sexuality, HIV status and education level should always be taken into account. Association between HPV prevalence and level of CD4 cells or HIV virus load was seen. In which way use of Antiretroviral Therapy (ART) could decries the risk for HPV infections is still discussed. When cytology was performed only few high-grade squamous intraepithelial lesion (HSIL) were found. OUTLOOK Standardisation and expansion of preventive screening for cervical dysplasia and carcinoma for pregnant WLWH is necessary. Then better comparability of the data will also be achieved.

Prevalence of HPV infection among Thai schoolgirls in the north-eastern provinces in 2018: implications for HPV immunization policy. IJID REGIONS 2023; 7:110-115. [PMID: 37009571 PMCID: PMC10050483 DOI: 10.1016/j.ijregi.2023.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 02/27/2023] [Accepted: 02/27/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVE The aim of this study was to determine the prevalence of high-risk (HR) and vaccine-type human papillomavirus (HPV) infection among Thai schoolgirls who were not included in the national HPV immunization program. METHODS Cross-sectional surveys were conducted among grade 10 (15-16 years old) and grade 12 (17-18 years old) schoolgirls in two provinces of Thailand. Urine samples were collected using the Colli-PeeⓇ device from November 2018 to February 2019. The samples were initially tested using CobasⓇ 4800. Subsequently, all Cobas-positive samples and 1:1 matched Cobas-negative samples were tested by AnyplexⓇ assay. Prevalences of any HPV, any HR HPV, vaccine-type HPV, and individual HR HPV types were estimated by school grade. RESULTS Prevalences of any HPV and any HR HPV were 11.6% and 8.6% for grade 10, and 18.5% and 12.4% for grade 12 schoolgirls, respectively. Prevalences of bivalent vaccine-type HPV infection in grades 10 and 12 were 3.4% and 4.5%, respectively. Prevalences of quadrivalent and nonavalent vaccine-type HPV infections were 4.0%/6.6% and 6.4%/10.4% in grades 10 and 12, respectively. HPV16 was the most common type detected, followed by HPV58, 51, and 52. Circulating HR HPV types were similar between the school grades. CONCLUSION A substantial burden of HR HPV infections was found among unvaccinated high school girls in Thailand.

Abstract
HPV is the most prevalent sexually transmitted diseases causing a variety of clinical manifestations ranging from warts to cancer. This study aimed to examine the challenges and needs of HPV-positive women. In this qualitative study, we analyzed data extracted from semi-structured face-to-face interviews with 31 Iranian HPV-positive women using a conventional content analysis approach using MAXQDA.10 software. Data were collected from her at the women's clinic from 21 January 2022 to her 19 February 2022. The sampling process was purposeful, and the accuracy of this study was ensured according to her 4 criteria suggested by Guba and Lincoln. Four themes were identified from the interviewing of HPV-positive women that include: Needing support and counseling to adapt to the disease, needing counseling and training to improve the disease, needing a qualified health care provider, needing proper health care services. HPV-positive women had many adverse such as reproductive health challenges (Menstruation cycle, delivery type, fertility, pregnancy, and breastfeeding), low control, confusion, cancer-related concerns, relationship problems, sexual concerns, uncertainty, stigma, low trust, social impact, non-disclosure of results, idiosyncratic prevention, indirect clinical interaction, changes in sexual behavior. HPV-positive women face many challenges and seek information to address them. Therefore, at the primary level, providers need to be aware of the needs of these patients needs in order to make the necessary consultations.

Geographical risk pattern and temporal trends in incidence of HPV-related cancers in northern Thailand: A population-based study. PLoS One 2022; 17:e0270670. [PMID: 35763509 PMCID: PMC9239466 DOI: 10.1371/journal.pone.0270670] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 06/14/2022] [Indexed: 12/24/2022] Open
Abstract
Background The burden of HPV-related cancers in different regions worldwide varies according to several factors. This study aims to measure inequality in the risk of incidence of HPV-related cancers in term of geographical risk patterns in northern Thailand using a population-based cancer registry data. Methods Trends in age-standardized HPV-related cancer incidence were calculated for the 2008–2017 time period. The Besag-York-Molli´e model was used to explore the spatial distribution of the relative risk (RR) of HPV-related cancers at the district level. A higher RR reflects a larger disparity. The geographical risk pattern of the diseases in two periods, 2008–2012 and 2013–2017 were described and compared. Results From 2008 to 2017, the incidence of oropharyngeal and anal cancers showed a slightly increased trend in males but remained stable in females, the incidence of vulvar, vaginal and penile cancers were stable while the incidence of cervical cancer decreased. The RR range was closer to 1 in the second period compared to the first period. This suggests a decrease in the disparities of incidence of cervical cancer. However, in some areas near the Thai-Myanmar border, the RR values remained high. Conclusion The incidence rate of most HPV-related cancers remained low and stable over the study period in northern Thailand. For the most common HPV-related malignancy, cervical cancer, the incidence rate steadily decreased but with marked geographic disparities, possibly reflecting health inequity especially in the border areas.

Abstract
Background The careHPV test as a primary screening method for cervical cancer has been proven to be the best option for Uyghur women in Xinjiang in a previous study. In this research, we aim to discuss the appropriate age for Uyghur women in Xinjiang to be screened for cervical cancer using careHPV. Methods Eleven thousand women aged 20–69 years old (mean age 38.93 ± 9.74) from South Xinjiang were screened using careHPV and liquid‐based cytology, and the positive results were referred for colposcopy and cervical biopsy. A questionnaire regarding basic social characteristics, sexual practices, and reproductive history was administered to each woman. The age‐specific prevalence of HPV positivity, cytology abnormality, and cervical intraepithelial neoplasia (CIN) 2+ in ≥25, ≥30, and ≥35 age groups were analyzed, and the diagnostic value of careHPV in the three age groups was evaluated. The chi‐squared test was used to compare the differences between age groups. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve were calculated. Results The women were mostly married (76.3%) and delivered at 15–19 years of age (61.4%). The HPV infection rate was 9.15% and detection rates of CIN2+ and invasive cervical cancer were 1.53% (1530/100,000) and 0.25% (250/100,000), respectively. The first peak of HPV(+) appeared at the age of 30–34, while CIN2+ appeared at 35–39. CareHPV performed similarly well in the three age groups. Conclusion Based on the results of our study, Uyghur women in Xinjiang should be recommended to initiate cervical cancer screening at the age of 30 years when screened using careHPV.

Abstract
Human papillomavirus (HPV) is one of the most common sexually transmitted infections in men and women. Most HPV studies have focused on vaccination toward women to prevent consequences of developing cervical cancer. However, persistent infections can cause penile, anal, and oropharyngeal cancers in men. Therefore, recent public health recommendations toward vaccination in men have been raised. There is limited HPV prevalence data among men in many countries, including Thailand. We conducted HPV sera IgG ELISA testing on a repository sera of Thai men (average age 21 years old) entering the Royal Thai Army as recruits in 2013 (n = 1000). HPV IgG antibodies against virus-like particles of HPV- type 6, 11, 16e, and 18 were evaluated using a commercial ELISA kit. Overall, the anti-HPV IgG was 47% (95% CI: 44%-50%). HPV seroprevalence was significantly associated with residence regions with the highest prevalence in South (64%), but not associated with educational level, marital status, or type of residence. This data suggested that almost half of the Thai men in this cohort were exposed to HPV by the age of 21. Thus, HPV vaccination provided to male adolescents should be considered for disease prevention and minimizing transmission to sexual partners.

Abstract
INTRODUCTION To achieve the Sustainable Development Goals (SDGs) target 2030, the United Nations (UN) endorsed tobacco use reduction, which is essential in decreasing unnecessary deaths caused by tobacco-induced disease. This study investigates the association between tobacco use and Human Papillomavirus (HPV) infection in clinically normal uterine cervix populations from the SDGs perspective. METHODS This study is a 7-year cross-sectional study of a clinically normal uterine cervix population, based on negative Visual Inspection of Acetic Acid (VIA). Subjects were recruited consecutively from the medical records of several public and private health providers in Jakarta. The Statistical Product and Service Solutions (SPSS) for Windows version 20.0 were used to analyze the data. RESULTS A total of 1397 negative VIA subjects were collected, consisting of 4.9% (69/1397) tobacco users, and 95.1% (1328/1397) non-users. HPV-DNA positive were 4.3% (3/69) in the tobacco user group and 3.7% (49/1328) in the non-user group. Statistical analysis showed unadjusted OR was 1.19 (95% CI: 0.36–3.91, p=0.778) and adjusted OR was 1.18 (95% CI: 0.36–3.89, p=0.786). High-risk HPV (hrHPV) infections of tobacco and non-tobacco users’ groups were found in 2/3 and 27/49 (55.1%), respectively. CONCLUSIONS This study showed an insignificant statistical association between tobacco use and HPV infection in normal uterine cervix. However, the proportion of hrHPV infection was higher in tobacco users than non-users. From the SDGs perspective, cervical cancer is closely related to tobacco use and poverty. Further study is needed to support this result and evaluate other co-factor role-related cervical cancer history to achieve SDGs in 2030.

Abstract
Human papillomavirus (HPV) has more than 100 different types, some of which are associated with cancer. The most common example is that of cervical cancer, which is associated with HPV16 and HPV18. Here, we performed next-generation sequencing (NGS) to type 2436 samples obtained from Korean women to elucidate the correlation between multiple infections, virus types, and cytology. NGS revealed that types 58, 56, and 16 were the most common in high-risk (HR) types, whereas types 90, 54, and 81 were the most common in low-risk (LR) types. The incidence of atypical squamous cells of undetermined significance (ASCUS) or high-grade squamous intraepithelial lesion (HSIL) was 11.45% in single-type cases and 27.17% in multiple infections by the two types of HPV. ASCUS or HSIL was 29.79% in only the HR type multiple infections and 29.81% in mixed high- and low-risk types of multiple infections, whereas it was 18.79% in LR type multiple infections (P ≤ 0.0001). Co-infection by LR-HPV and HR-HPV is therefore more likely to cause cell lesions. Collectively, these results show that the higher the incidence of multiple infections, the greater the frequency of cell lesions. Thus, to predict the clinical symptoms, it would be beneficial to confirm the HPV type and multiple infections using NGS, although this could be relatively expensive.

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

Abstract
Determining the spatial distribution of human papillomavirus (HPV) and performing accurate public health analyses helps to distinguish areas of healthcare that require further research, and enables therapeutic techniques and approaches in healthcare to be focused more accurately. A total of 4,560 women were enrolled in the present study. Flow-through hybridization and gene chip assays were used to detect the genotypes of HPV infection. Heat maps were then generated to present the spatial distribution of HPV infections in Zhejiang Province according to genotype. Of the exfoliated cervical cell samples from the 4,560 women, HPV was detected in 1,886 samples. HPV-16, -58, -52 and -18 were the most prevalently identified genotypes in the population included in the present study. HPV-16 and -58 infections were mainly distributed in the northern and central regions of Zhejiang Province, such as in Hangzhou and Shaoxing, where the prevalence was higher than that in the southern regions (P<0.05). HPV-18 infection was widespread throughout Zhejiang Province, but had a much lower infection rate in Ningbo and Huzhou (P<0.05). High infection rates of HPV-52 were mainly detected in Hangzhou and the eastern coastal areas of Wenzhou, with a relatively low rate of infection in the center of the province (P<0.05). In conclusion, HPV-16, -58, -52 and -18 were the four most prevalent HPV genotypes observed in Zhejiang Province. Heat maps were created to display the spatial distribution of HPV infection according to genotype, which varied by geographical regions. The results indicate that for individuals in Ningbo or Wenzhou, bivalent or quadrivalent vaccines may be suitable, but for those in Hangzhou and Shaoxing, nonavalent vaccines are strongly recommended.

Barriers to cervical cancer screening and acceptability of HPV self-testing: a cross-sectional comparison between ethnic groups in Southern Thailand. BMJ Open 2019; 9:e031957. [PMID: 31685510 PMCID: PMC6858097 DOI: 10.1136/bmjopen-2019-031957] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 10/01/2019] [Accepted: 10/07/2019] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Cervical cancer rates are higher in low-resourced countries than high, partly due to lower rates of screening. Incidence in Thailand is nearly three times higher than in the USA (16.2 vs 6.5 age-standardised incidence), even with Thailand's universal health coverage, which includes screening, suggesting that alternative methods are needed to reduce the burden. We investigated barriers to screening, as well as acceptability of self-collection human papillomavirus (HPV) testing as a primary form of cervical cancer screening among Buddhist and Muslim communities in Southern Thailand. METHODS 267 women from the Buddhist district of Ranot and Muslim district of Na Thawi, Songkhla were recruited to complete a survey assessing knowledge and risk factors of HPV and cervical cancer. Participants were offered an HPV self-collection test with a follow-up survey assessing acceptability. Samples were processed at Prince of Songkhla University and results were returned to participants. RESULTS 267 women participated in the study (132 Buddhist, 135 Muslim), 264 (99%) self-collecting. 98% reported comfort and ease, and 70% preferred it to doctor-facilitated cytology. The main predictor of prior screening was religion (92% Buddhist vs 73% Muslim reporting prior Pap). After adjustment with multivariate logistic models, Muslim women had an OR of prior Pap of 0.30 compared with Buddhist (95% CI: 0.12 to 0.66). CONCLUSIONS Self-collection HPV testing was highly acceptable across religious groups, suggesting that it could be beneficial for cervical cancer reduction in this region. Focus should be put into educating women from all backgrounds about the importance of screening to further improve screening rates among Thai women.

Abstract
Background Despite being preventable, cervical cancer remains a major health concern among women. Persistent Human Papillomavirus (HPV) and other viral co-infections may influence cervical dysplasia. We determined and compared the prevalence and risk factors of cervical viral infections among the tribal and general population of southern coastal Karnataka, India. Methods A population-based cross-sectional survey was conducted among 1140 and 1100 women from tribal and general population, respectively. Cervical infections with HPV, Epstein-Barr Virus (EBV), Cytomegalovirus (CMV) and Herpes-Simplex Virus (HSV) were examined using polymerase chain reactions (PCR) and DNA sequencing. Results HPV prevalence was higher among tribal women (40.6%) than general population (14.3%) while the prevalence of EBV (55.1%) and CMV (49.4%) were lower among tribal women than general population (74.3% and 77.5%, respectively). HSV infection was observed in tribal women only (1.8%). Among HR-HPV strains, HPV-18 was predominant among tribal population (28.3%) while, HPV-16 was predominant among the general population (9.1%). Infections were associated with age, educational status, unemployment and personal hygiene of tribal women. Phylogenetic analysis revealed that HPV-16 variants of tribal participants were closely related to non-European sublineages indicating greater risk of HPV persistence and carcinogenesis. Conclusion The study provides a comparative estimate for DNA virus infections of the cervix among women from general as well as tribal population in this region and also reveals a different type-specific pattern of viral infection. Further research is required to delineate the role of specific interactions between multiple virus infections and their role in carcinogenesis.

Abstract
The use of the human papillomavirus (HPV) vaccine was recently approved in Mainland China. This study determined the knowledge and attitudes of young women aged 20 to 35 years in Fujian Province, China, with regard to HPV and vaccination and explored the potential factors influencing their attitudes toward HPV vaccination. This was a cross-sectional study that collected data regarding the knowledge on and attitudes toward HPV and vaccination using questionnaires. Furthermore, the prevalence of HPV was determined from the sampled participants. A total of 1001 young women were included in the survey. This study demonstrated that the HPV prevalence rate was 15.7% (157/1001). Among all patients, 44.9% (n = 449) had heard of HPV; however, detailed knowledge about HPV was lacking. The majority (83.7%) expressed a willingness to be vaccinated. Specifically, knowledge of the dangers of HPV infection was significantly associated with the willingness to be vaccinated. In this study, women cited some concerns and expressed high expectations for the HPV vaccine, but the costs of vaccination reduced their willingness to be vaccinated. This study found that most patients did not have a detailed knowledge of HPV. Thus, there is a need for continued HPV promotion and education efforts, especially on the dangers of HPV infection, among young women aged 20 to 35 years in Fujian Province, China. Furthermore, it is important to subsidize the costs of vaccination for promoting vaccination campaigns in China.

SAGE Open Med 2018; 6:2050312118765604. [PMID: 29623202 PMCID: PMC5881963 DOI: 10.1177/2050312118765604] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Accepted: 02/26/2018] [Indexed: 12/19/2022] Open
Abstract
Background: Among developing countries, Thailand shows no increase in the incidence of human papillomavirus–driven oropharyngeal cancer. The causal role of human papillomavirus infection in this pathology has not been researched thoroughly. Methods: A hospital-based, case–control study was performed which included 104 patients with newly diagnosed oral and oropharyngeal squamous cell carcinomas and 104 individuals without cancer. The Cervista high-risk human papillomavirus and 16/18 assays were used to detect human papillomavirus. Odds ratios were used to assess the association between high-risk genotypes of human papillomavirus and the cancers. Results: High-risk human papillomavirus was detected in 4 of 52 (7.7%) oral cancer cases, 6 of 52 (11.5%) oropharyngeal cancer cases, and 1 of 104 (0.96%) control subjects. Of 104 cancer patients in the study, 83 were smokers. High-risk human papillomavirus was significantly associated with oropharyngeal cancer (odds ratio = 13.44, 95% confidence interval = 1.6–114.8) but was nonsignificantly associated with oral cancer (odds ratio = 8.58, 95% confidence interval = 0.9–78.9). However, after adjustment for smoking, high-risk human papillomavirus was determined to be nonsignificantly associated with oropharyngeal cancer (adjusted odds ratio = 5.83, 95% confidence interval = 0.8–43.5). Conclusion: Although low human papillomavirus prevalence was observed, the rate of high-risk human papillomavirus infection in the cancer group was still higher than that in the control group. Smoking may have an influence on the etiology of human papillomavirus–related cancers. However, the study is underpowered to clarify the role of human papillomavirus as the independent risk factor for oral and oropharyngeal cancers in the Thai population.

Abstract
Introduction Cervical cancer is the second most common cancer among women in the developing countries and the seventh commonest cancer in the developed countries. Human papillomavirus (HPV) is now known to be the main factor in the aetiology of cervical cancer with over 99.7% of cases being associated with previous high risk HPV (hrHPV) infection. This study was aimed to determine the prevalence and risk factors for genital hrHPV infection among women attending the out-patient clinics of the Lagos University Teaching Hospital. Methods This was a cross-sectional study involving a total of 200 women. Questionnaires were administered to collect data such as sociodemographic, reproductive and sexual histories. Endocervical swab samples were then taken from each participant. Samples were analyzed by polymerase chain reaction (PCR) using consensus primers targeted against the hrHPV viruses. Results The prevalence of hrHPV in the study was 36.5%. The most predominant HPV subtypes were 31 (25.0%), 35 (8.0%) and 16 (3.5%) with the largest proportion (76.1%) of the tested samples being positive for only a single hrHPV subtype. The study showed statistically significant associations between early age at coitarche (P = 0.032) and increasing number of lifetime sexual partners (P = 0.001) with genital hrHPV infection. Conclusion The prevalence of hrHPV was high in Lagos with the majority of test positive samples having only a single HPV genotype. We demonstrated early age of sexual debut and increasing number of lifetime sexual partners as the most important factors associated with genital hrHPV infection.

Abstract
Human papillomavirus (HPV) is the leading cause of cervical cancer. Urine-based HPV testing offers a simple and non-invasive method because of its increasing acceptance. A total of 164 pairs of cervical swab and urine samples from Thai women who underwent cervical cancer screening were used for HPV testing with HPV GenoArray Diagnostic Kits. The overall concordance percentage for HPV detection in the cervical swab and urine samples was 65.2%. The HPV genotypes most commonly detected were HPV16 and HPV18. An analysis of the urine samples and a second analysis of the cervical swab samples showed that the differences in the overall HPV detection rate between women with normal and abnormal cytology were not significant (p > 0.05). Urine samples processed with the GenoArray assay is an alternative for women who decline to undergo Pap smear even though it is not ideal as the first-line screening option.

Abstract
Despite the high incidence of cervical cancer in Thailand, large population-based studies on cervical cytology and HPV prevalence and genotype distribution are rare. This study aimed to determine cervical cytology results and the prevalence and distribution of HPV among Thai females in Bangkhayaeng subdistrict, Pathumthani province, Thailand. Of 4681 female inhabitants, aged 20–70 years, 1523 women finally participated in the study. Cervical samples using liquid-based cytology were collected during February–August 2013 and analyzed for HPV genotype by the LINEAR ARRAY® HPV Genotyping Test (Roche, USA). All participants with abnormal cytology or HPV positivity underwent colposcopy and biopsy. Of 1523 eligible women, 4.1% had abnormal cytology including ASC-US (2.4%), LSIL (1.0%), and HSIL (0.5%). The HPV infection rate was 13.7%. The prevalences of high-risk, probable high-risk, and low-risk HPV types were 5.6%, 3.5%, and 6.8%, respectively. The most common high-risk HPV types detected were HPV-16 (1.31%), HPV-51 (1.25%), and HPV-52 (1.25%). The most common probable high-risk and low-risk HPV types detected were HPV-72 (1.51%), HPV-62 (1.38%), and HPV-70 (1.18%). The rates of CIN2–3 and cancer in this cohort were 1.4% and 0.3%, respectively. In conclusion, HPV prevalence in this study was lower than reported in studies conducted in Western countries or other Asia countries, despite the high prevalence of CIN2 + and cancer. HPV type screening results of the general population in Bangkhayaeng subdistrict were similar to those reported in other countries, with HPV-16 the most common type. However, higher frequencies of HPV-51 and HPV-52 were observed. Despite the availability of a free screening program in this area, the participation rate remains low. The largest population-based study using liquid-based cytology and Linear array HPV genotyping in Thailand. Low prevalence of high risk HPV in Thailand despite high incidence of cervical cancer. Higher ratio of HPV-51, HPV-52 after HPV-16 in this cohort. Almost abnormal results underwent colposcopy and biopsy with histological confirmation.

J Gynecol Oncol 2017; 28:e47. [PMID: 28657217 PMCID: PMC5540715 DOI: 10.3802/jgo.2017.28.e47] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Revised: 01/30/2017] [Accepted: 03/12/2017] [Indexed: 12/31/2022] Open
Abstract
Objective We performed a pooled analysis to examine cigarette smoking and household passive smoke exposure in relation to the risk of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia grade 2+ (CIN2+). Methods Data were pooled from 12 cross-sectional studies for cervical cancer screenings from 10 provinces of China in 1999–2007. A total of 16,422 women were analyzed, along with 2,392 high-risk-HPV (hr-HPV) positive women and 381 CIN2+ cases. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression models controlling for sexual and non-sexual confounding factors. Results There was an excess risk between active smoking and hr-HPV infection and CIN2+. Adjusted OR for ever smokers vs. never smokers was 1.45 (95% CI=1.10–1.91), for hr-HPV infection and 1.89 (95% CI=1.03–3.44), for CIN2+. Passive smoking had a slightly increased risk on the hr-HPV infection with adjusted OR 1.11 (1.00–1.24), but no statistical association was observed between passive smoke exposure and CIN2+. Compared with the neither active nor passive smokers, both active and passive smokers had a 1.57-fold (95% CI=1.14–2.15) increased risk of HPV infection and a 1.99-fold (95% CI=1.02–3.88) risk of CIN2+. Conclusion Our large multi-center cross-sectional study found active smoking could increase the risk of overall hr-HPV infection and CIN2+ adjusted by passive smoking and other factors. Passive smoking mildly increased the risk of HPV infection but not the CIN2+. An interaction existed between passive tobacco exposure and active smoking for hr-HPV infection and the CIN2+.

Abstract
OBJECTIVES To estimate the prevalence and factors associated with Human Papillomavirus (HPV) infection, HPV genotypes and cytological/histological high-grade (HSIL+/CIN2+) lesions. METHODS We conducted a cross-sectional study within a prospective cohort of HIV-infected women on combination antiretroviral therapy (cART). Cervical specimens were collected for cytology and HPV genotyping (Papillocheck®). Any women with High-Risk-HPV (HR-HPV), and/or potentially HR-HPV (pHR-HPV) and/or ASC-US or higher (ASC-US+) lesions were referred for colposcopy. Factors associated with HR-HPV infection and with HSIL+/CIN2+ lesions were investigated using mixed-effects logistic regression models. RESULTS 829 women were enrolled: median age 40.4 years, on cART for a median of 6.9 years, median CD4 cell-count 536 cells/mm3, and 788 (96%) with HIV-viral load<50copies/mL. Of 214 (26%) infected with HPV: 159 (19%) had ≥1 HR-HPV, of whom 38 (5%) HPV52, 22 (3%) HPV16, 9 (1%) HPV18; 21 (3%) had pHR-HPV, 34 (4%) low risk-HPV infection, and 56 (26%) had multiple genotypes. Younger age, low CD4 cell-counts and low education were independently associated with HR-HPV infection. 72 women (9%) had ASC-US+ and 28 (3%) HSIL+/CIN2+ lesions. HR-HPV infection was independently associated with HSIL+/CIN2+ lesions. CONCLUSION The prevalence of HPV infection and of cervical lesions was low. The HPV genotype distribution supports the use of 9-valent vaccine in Thailand.

Abstract
Introduction: Cervical cancer probably represents the best-studied human cancer caused by a viral infection and the causal association of this preventable cancer with human papilloma virus (HPV) is well established. Worldwide there is a scarcity of data regarding HPV prevalence with vast differences existing among populations. Objective: The aim of this meta-analysis was to determine the community-based HPV prevalence estimates among asymptomatic women from urban and rural set ups and in participants of cancer screening clinics. Study design: Systematic review and meta-analysis. Methods: PubMed-Medline, CINAHL, Scopus, and Google scholar were systematically searched for studies providing prevalence data for HPV infection among asymptomatic women between 1986 and 2016. Results: The final analysis included 32 studies comprising a population of 224,320 asymptomatic women. The overall pooled HPV prevalence was 11% (95% confidence interval (CI), 9%-12%). The pooled HPV prevalence of 11% (95% CI, 9%-11%) was observed among women attending cervical cancer screening clinics. The pooled HPV prevalences were 10% (95% CI 8%-12%) and 11% (95% CI 4%-18%) from urban and rural areas respectively, indicating higher infection rates among the rural women with the least access to cancer screening and cancer care. Conclusion: The prevalence rates in this systematic quantitative review provide a reliable estimate of the burden of HPV infection among asymptomatic women from developed as well as developing nations. Rural women and women attending cervical cancer screening programmes feature higher genital HPV prevalences compared to their urban counterparts.

Abstract
Background This study was designed to determine the Human papillomavirus (HPV) prevalence and its distribution of genotypes in various regions of Yunnan Province, China. Method In this study, participants were recruited during routine gynecologic examination between Oct 2013 and Feb 2015. A total of 17,898 women were recruited. Polymerase chain reaction was used for detecting the HPV positive samples and HPV geno-array test was used for genotyping. Results The overall HPV infection rate (19.9 %) among the south-western women was significantly higher (P = 0.001) than that among the north-western (18.0 %), south-eastern (13.3 %), north-eastern (11.1 %) and central women (12.9 %). The high-risk (HR) (18.1 %, P = 0.001) and single genotype (16.7 %, P = 0.001) infection rates among the South-western women were also significantly higher than those of among the north-western (13.9 %, 11.3 %), south-eastern (11.6 %, 10.5 %), north-eastern (9.6 %, 9.1 %) and central women (10.5 %, 10.0 %), respectively. While, the infections with multiple HPV (4.2 %) genotypes were significantly more common (P = 0.001) among women in north-western Yunnan than women in the south-western (1.3 %, 3.1 %), south-eastern (1.7 %, 2.7 %), north-eastern (1.5 %, 2.0 %) and central Yunnan (2.4 %, 2.9 %). A total of 30 HPV genotypes were detected; among them 13 were HR-HPV, 3 were PHR-HPV (Potential High risk), 8 were LR-HPV (Low risk) and six were unclassified. The most common HPV genotypes were HPV-52, 16, 58, 53 in control group, HPV-16, 52, 58, 39 and 53 in CINI (Cervical intraepithelial Neoplasia), HPV-52, 16, 58, 33, 53 and 81 in CINII, HPV16, 58, 18, 52, 81 in CINIII and HPV-16 18, 58, 52 in cervical cancer (CC), respectively. Such variation has also been observed about distribution of HPV genotypes distribution among single and multiple infections. Conclusion This study gives an epidemiological estimate of HPV prevalence and different genotype distribution in various region of Yunnan province and further explains its prevalence in different neoplastic lesions. Overall HPV-16, 52, 58, and 18 are the leading HR-HPV genotypes.

Abstract
HPV genotypes have distinct distributions among various ethnic populations worldwide. In December 2013, 237 and 159 cervical samples were collected from Hani and Han ethnic women, respectively, in Mojiang, a rural county in southern Yunnan. The overall HPV infection rate (21.1%) among the Hani women was significantly higher than that among the Han women (12.6%). The high-risk (HR) and low-risk (LR) HPV and single- and multiple-genotype infection rates among the Hani women were 11.0%, 4.6%, 15.6%, and 5.5%, respectively. HPV-16 (3.8%) was the most prevalent genotype among the Hani women, followed by HPV-52 (1.7%), HPV-31 (0.8%), and HPV-33 (0.8%). Comparatively, the Han women had lower infection rates of high-risk (8.2%), low-risk (1.2%), single-genotype (9.4%), and multiple-genotype HPV infections (3.1%). HPV-16 (3.1%) was also the predominant genotype among the Han women, followed by HPV-52 (1.3%), HPV-33 (0.6%), HPV-44 (0.6%), and HPV-54 (0.6%). The area background, number of children, and past history of STIs were recognized as potential risk factors for HPV infection. Rural background, age, education level, number of children, and illness history were significantly associated with HPV infection among the Hani women. These findings highlight the urgent need for HPV prevention and control strategies in Yunnan, particularly for the Hani ethnic women.

Abstract
OBJECTIVES Genital HPV infection in men causes benign and cancerous lesions, the incidence of which differs by age. The goal of this work was to comprehensively evaluate incidence and clearance of individual HPV genotypes among men by age group. METHODS HIV-negative men ages 18-70 with no history of anogenital cancer were recruited for the HPV Infection in Men (HIM) Study. Participants completed clinical exams and questionnaires every six months for up to ~4 years. Genital specimens underwent HPV genotyping, with associations between age and HPV assessed using Cox analyses. RESULTS 4085 men were followed for a median of 48.6 months (range: 0.3-94.0). Significantly lower HPV incidence rates were observed among the oldest age group (55-70 years) for grouped high-risk (incidence rate ratio [IRR]=0.71), HPV16 (IRR=0.54), grouped low-risk (IRR=0.74), and HPV6 (IRR=0.57) infections compared to men ages 18-24. However, incidence of the grouped 9-valent HPV vaccine types remained constant across the lifespan. Likelihood of HPV6 and HPV16 clearance remained constant until age 54, then increased significantly for men ages 55-70 (adjusted hazard ratio [AHR]=1.92 and 1.65, respectively). CONCLUSIONS Men remain susceptible to HPV infections throughout their lifespan, highlighting the need for prevention efforts with long-lasting duration.

Abstract
BACKGROUND Human papillomavirus (HPV) infections in Thailand are a public health concern, but information on HPV infection in sex workers and men who have sex with men (MSM) is limited. The aim of this study was to measure the prevalence and genotype distribution of HPV among low- and high-risk, HIV-negative populations. METHODS A total of 300 participants were categorized as general women, female sex workers, MSM, and MSM sex workers. Human papillomavirus infections were identified by the Papanicolaou test and nested polymerase chain reaction. A phylogenetic analysis of partial HPV L1 genes was performed. RESULTS Abnormal cytology was found in 5% of general women, 10% of female sex workers, 24% of MSM, and 28% of MSM sex workers. Human papillomavirus was detected in 9% of general women, 13% of female sex workers, and 30% in both MSM and the MSM sex workers. The prevalence of HPV high-risk genotypes was significantly higher in female sex workers and MSM, whereas low-risk genotypes and genital warts were significantly higher in MSM sex workers. Significantly more patients with genital warts and cervical intraepithelial neoplasia I/anal intraepithelial neoplasia I harbored low-risk genotypes, whereas those with cervical intraepithelial neoplasia II/anal intraepithelial neoplasia II harbored high-risk genotypes. CONCLUSIONS High- and low-risk HPV genotypes persist in high-risk groups in Bangkok. Some genotypes infecting at-risk populations are not vaccine preventable. These findings may help to elucidate the prevalence of HPV infections in Thailand and serve as the basis for additional investigations into risk factors for these populations.

Abstract
BACKGROUND The prevalence of human papillomavirus (HPV) infection and the distribution of different HPV genotypes vary greatly within different geographical and ethnic populations, especially in Asia. The HPV infection data based on regional population are extremely important for researchers to develop new efficient HPV screening assays and estimate the effect of vaccines on preventing from cervical cancer. METHODS A total of 78,355 women from Guangdong Province, China, whose ages were from 18 to 75 years were enrolled in this study. All epidemiological data were obtained by face-to-face interview. Cervical exfoliated cells were collected, and HPV-DNA test was conducted with the matrix-assisted laser desorption/ionization time-of flight mass spectrometry. RESULTS The overall HPV infection prevalence in the study population was 7.3%. The top 6 HPV genotypes were HPV16 (1.5%), HPV52 (1.2%), HPV58 (1.0%), HPV18 (0.7%), HPV45 (0.5%), and HPV6 (0.5%), accounting for 69.7% of all detected HPV infection types. Two peaks of HPV infection were detected in the population of old age group (>50; 9.6%) and young group (<25; 8.2%). Infection with single genotype HPV (6.2% in all; 85.7% in HPV-positive women) was more frequent than infection with multiple HPV (1.0% and 14.3% respectively). Results of multivariate logistic regression revealed that sexual active years, numbers of sexual partner, and numbers of pregnancy were risk factors of HPV infection. CONCLUSIONS This study provides useful epidemiological information on cervical HPV infection prevalence in general female population from Guangdong Province, China. In this population, HPV infection prevalence was 7.3%, and genotypes HPV16, HPV52, and HPV58 showed a relatively high prevalence.

Abstract
BACKGROUND Some infectious agents have been shown to be human carcinogens. The current study focused on estimation of cancer burden attributable to infection in different regions of Asia. METHODS By systematically reviewing previous studies of the infection prevalence data of 13 countries in Asia and relative risks of specific cancers, we calculated the population attributable fraction of carcinogenic infections. Using data from GLOBOCAN 2012, the overall country-specific and gender-specific number of new cancer cases and deaths resulting from infection were estimated. RESULTS Across 13 principal Asian countries, the average prevalence and range was 6.6% (0.5% in Japanese women to 15.0% in Vietnamese men) for hepatitis B virus (HBV), 2.6% (0.3% in Iran to 5.1% in Saudi Arabia) for hepatitis C virus (HCV), 7.9% (2.8% in Pakistan to 17.7% in China) for human papillomavirus (HPV), and 61.8% (12.8% in Indonesia to 91.7% in Bangladesh) for Helicobacter pylori (HP). The estimated total number of cancer cases and deaths caused by infection in these 13 countries were 1 212 026 (19.6% of all new cancer cases) and 908 549 (22.0% of all deaths from cancer). The fractions of cancer incidence attributable to infection were 19.7% and 19.5% in men and women, respectively. The percentages of cancer deaths attributable to infection were 21.9% and 22.1% in men and women, respectively. Among the main infectious agents, HP was responsible for 31.5% of infection-related cancer cases and 32.8% of infection-related cancer deaths, followed by HBV (28.6% of new cases and 23.8% of deaths), HPV (22.0% of new cases and 27.3% of deaths), and HCV (12.2% of new cases and 10.6% of deaths). CONCLUSIONS Approximately one quarter of all cancer cases and deaths were infection-associated in Asia, which could be effectively prevented if appropriate long-term controls of infectious agents were applied.

Abstract
BACKGROUND Northern Thailand is a region with a high cervical cancer incidence. Combined high-risk HPV (hrHPV) DNA testing and cytology (co-testing) has increasingly gained acceptance for cervical cancer screening. However, to our knowledge, data from a population-based screening using co-testing have not been available in this region. This study therefore aimed to evaluate the performance of cytology and hrHPV test in women in northern Thailand. MATERIALS AND METHODS Cervical samples were collected for hybrid capture 2 (HC2) testing and liquid-based cytology from women aged 30 to 60 years who were residents in 3 prefectures of Chiang Mai in northern Thailand between May and September 2011. Women with positive cytology were referred to colposcopy, while women with positive for HC2 only were followed for 2 years. RESULTS Of 2,752 women included in this study, 3.0% were positive in both tests, 4.1% for HC2 only, and 1.3% had positive cytology only. At baseline screening, positive HC2 was observed in 70.6% among cytology-positive women compared with 4.3% among cytology-negative women. The prevalence of positive HC2 or cytology peaked in the age group 35-39 years and was lowest in the age group 55-60 years. High-grade squamous intraepithelial lesion or worse lesions (HSIL+) were histologically detected in 23.5% of women with positive baseline cytology and in 9.8% of women with positive baseline HC2 only on follow-up. All women with histologic HSIL+ had positive baseline HC2. CONCLUSIONS The hrHPV test is superior to cytology in the early detection of high-grade cervical epithelial lesions. In this study, the prevalence of histologic HSIL+ on follow-up of women with positive hrHPV test was rather high, and these women should be kept under careful surveillance. In northern Thailand, hrHPV testing has a potential to be used as a primary screening test for cervical cancer with cytology applied as a triage test.

Abstract
Background Cervical cancer is the most common cancer among women of reproductive age in Thailand. However, information on the prevalence and correlates of anogenital HPV infection in Thailand is sparse. Methods HPV genotype information, reproductive factors, sexual behavior, other STI and clinical information, and cervical cytology and histology were assessed at enrollment among one thousand two hundred and fifty-six (n = 1,256) HIV negative women aged 20–37 from Thailand enrolled in a prospective study of the natural history of HPV. The type-specific prevalence of HPV was estimated using cervical swab specimens from healthy women and women with a diagnosis of CIN 2/3 at baseline. Prevalence ratios (95% CI) were estimated using Poisson regression to quantify the association of demographic, behavioral, and clinical correlates with prevalent HPV infection. Results Overall, 307 (24.6%) and 175 (14.0%) of women were positive for any HPV type and any HR-HPV type, respectively; the most common types were 72, 52, 62, and 16. Among women diagnosed with CIN 2/3 at enrollment (n = 11), the most prevalent HPV types were 52 and 16. In multivariate analysis, HPV prevalence at enrollment was higher among women with: long-term combined oral contraceptive use, a higher number of lifetime sexual partners, a prior Chlamydia infection, and a current diagnosis of Bacterial Vaginosis. Conclusion The study findings provide important information that can be used in the evaluation of primary and secondary interventions designed to reduce the burden of cervical cancer in Thailand.

Abstract
Background Cervical cancer is the major cause of morbidity and mortality in Thai women. Nevertheless, the preventive strategy such as HPV vaccination program has not been implemented at the national level. This study explored the HPV prevalence and genotypic distribution in a large cohort of Thai women. Methods A hospital-based cervical cancer screening program at Chulabhorn Hospital, Bangkok and a population-based screening program at a rural Pathum Thani Province were conducted using liquid-based cytology and HPV genotyping. Results Of 5906 women aged 20–70 years, Pap smear was abnormal in 4.9% and the overall HPV prevalence was 15.1%, with 6.4% high-risk (HR), 3.5% probable high-risk (PR), and 8.4% low-risk (LR) HPV. The prevalence and genotypic distribution were not significantly different between the two cohorts. Among HR-HPV genotypes, HPV52 was the most frequent (1.6%), followed by HPV16 (1.4%), HPV51 (0.9%), HPV58 (0.8%), HPV18 (0.6%), and HPV39 (0.6%). Among LR-HPV genotypes, HPV72 and HPV62 were the most frequent while HPV6 and HPV11 were rare. HPV infection was found to be proportionately high in young women, aged 20–30 years (25%) and decreasing with age (11% in women aged >50). The more severe abnormal cytology results, the higher positivity of HR-HPV infection was observed. Conclusions In conclusion, HPV52, HPV16, and HPV51 were identified as the most common HR-HPV genotypes in Thai women. This study contributes genotypic evidence that should be essential for the development of appropriate HPV vaccination program as part of Thailand’s cervical cancer prevention strategies.

Abstract
OBJECTIVE To evaluate the prevalence of HPV infection among women from three districts of Tamil Nadu (Erode, Salem, and Namakkal). METHODS Between January 27, 2007, and December 15, 2009, 1800 women aged 20-70years who had normal cervical cytology were enrolled into a cross-sectional study. Participants completed interviews and provided first void urine samples for assessment of HPV infection. RESULTS Among 1699 eligible samples, 179 (10.5%) were HPV positive. HPV16 was the most common type (affecting 68 [4.0%] women), followed by HPV6 (58 [3.4%]). Among the 179 HPV-positive women, 71 (39.7%) were aged 36-45years. An annual income of less than 25 000 INR was significantly associated with HPV infection in all three districts (P<0.05). Regular intercourse was also associated with HPV in Erode and Salem (P<0.05). CONCLUSION Screening and prophylactic vaccines containing HPV16 and HPV6 should be promoted in western Tamil Nadu.

Abstract
Human papillomavirus (HPV) is causally associated with anal cancer, as HPV DNA is detected in up to 90% of anal intraepithelial neoplasias and anal cancers. With the gradual increase of anal cancer rates, there is a growing need to establish reliable and clinically relevant methods to detect anal cancer precursors. In resource-limited settings, HPV DNA detection is a potentially relevant tool for anal cancer screening. Here, we evaluated the performance of the Hybribio GenoArray (GA) for genotyping HPV in anal samples, against the reference standard Roche Linear Array (LA). Anal swab samples were obtained from sexually active men who have sex with men. Following DNA extraction, each sample was genotyped using GA and LA. The overall interassay agreement, type-specific, and single and multiple genotype agreements were evaluated by kappa statistics and McNemar's χ(2) tests. Using GA and LA, 68% and 76% of samples were HPV DNA positive, respectively. There was substantial interassay agreements for the detection of all HPV genotypes (κ = 0.70, 86% agreement). Although LA was able to detect more genotypes per sample, the interassay agreement was acceptable (κ = 0.53, 63% agreement). GA had poorer specific detection of HPV genotypes 35, 42, and 51 (κ < 0.60). In conclusion, GA and LA showed good interassay agreement for the detection of most HPV genotypes in anal samples. However, the detection of HPV DNA in up to 76% of anal samples warrants further evaluation of its clinical significance.

Abstract
BACKGROUND Bhutan has been engaged in good-quality cytology-based cervical screening since 2000 and has vaccinated >90% girls against human papillomavirus (HPV) since 2010. We explored the characteristics associated with lack of previous screening and screening coverage in women age ≥25 years. METHODS Women were invited at home or during their attendance at 2 outpatient clinics, in the capital, Thimphu, and nearby Lungthenphu. Age-adjusted odds ratios for lack of previous screening by selected characteristics were computed among 1,620 participating women. In Thimphu an invitation registry allowed to estimate screening history not only among participating women but also among additional 500 women who did not accept to join our study. RESULTS Among women who had a Pap smear, lack of previous screening was associated with age <35 or ≥45 years. It was also associated with some occupations; being single, or widowed/separated; and presence of HPV infection. Multiparity and use of contraceptive methods were associated with having been screened. In women invited at home in Thimphu screening history substantially differed by participation. Past screening attendance was 59% among women recruited in the 2 clinics, 53% in women who were invited from home and accepted the invitation, but only 25% in those who refused it. Based on all women recruited from home the estimate of population-based coverage in Thimphu is 34% (95% CI: 31-37). CONCLUSIONS Transition from an opportunistic screening to an all-reaching population-based screening is yet to be achieved in Bhutan, even in the capital. Better ways to target never-screened women are needed.

Abstract
BACKGROUND There has been no population-based study on human papillomavirus (HPV) prevalence or its genotypes in Bangladesh; a country eligible for GAVI funding for HPV vaccine. METHODS We used baseline survey data of a prospective cohort study that was conducted in one urban and one rural area of Bangladesh. A total of 997 urban and 905 rural married women, aged 13 to 64 years, were enrolled in the baseline during July-December, 2011. Information was collected on socio-demographic characteristics and potential risk factors for HPV infection followed by gynecological examination and collection of endocervical samples using the cervical cytobrush (Digene cervical sampler). HPV DNA testing was done by Polymerase Chain Reaction (PCR) using a consensus primer set. RESULTS Prevalence of any HPV infection was 7.7% with no significant difference between urban and rural women. Most common high-risk genotypes were HPV16, HPV66, HPV18, HPV45, HPV31 and HPV53. Urban women working as housemaids or garment workers were at higher risk of any HPV infection (OR = 2.15, 95% CI: 1.13-4.11) compared to housewives. Rural women whose husband lived overseas were almost two times more likely to have any HPV infection (OR = 1.93; 95% CI 1.05-3.55) compared to women whose husbands lived with them. CONCLUSION The prevalence of HPV infection among Bangladeshi women is similar to other regions of Asia. However, type-specific patterns are different. The study findings will inform the formulation of HPV vaccination policies in Bangladesh, monitoring the impact of vaccination programmes, and the identification of target populations for screening.

Abstract
Human papillomavirus (HPV) is a major cause of cervical cancer. More than 100 HPV genotypes have been identified; however the distribution varies geographically and according to ethnicity. The purpose of this study was to investigate the prevalence and distribution of HPV subtypes among Northeast Thai women. Subjects included 198 cases of SCCA and 198 age-matched, healthy controls. HPV-DNA was amplified by PCR using the consensus primers GP5+/6+ system followed by reverse line blot hybridization genotyping. The prevalence of high-risk HPV infection was 21 (10.1%) and 152 (76.8%) in the controls and in the cases, respectively. High-risk HPV significantly increased the risk for cervical cancer with an OR of 42.4 (95%CI: 22.4-81.4, p<0.001) and an adjusted OR of 40.7-fold (95%CI: 21.5-76.8, p <0.001). HPV-16 was the most prevalent HPV type in the SCCA (56.2%) followed by HPV-58 (17.8%) and HPV-18 (13.6%); whereas HPV-58 (46.4%) was a prominent genotype in the controls followed by HPV-16 (39.3%) and unidentified HPV types (25.0%). These findings indicate that HPV infection remains a critical risk factor for SCCA; particularly, HPV-16, HPV-58 and HPV-18. In order to eradicate cervical cancer, sustained health education, promoted use of prophylactics and a HPV-58 vaccine should be introduced in this region.

Abstract
High-risk (HR) human papillomavirus (HPV) testing is important in cervical cancer screening for triage colposcopy. The objective of the study was to evaluate the prevalence of HR HPV infection with different cervical cytological features among women undergoing health examination. A total of 2,897 women were retrospectively evaluated between May 2011 to December 2011. DNA was extracted from residual specimens collected during routine liquid-based cytology tests at the National Cancer Institute. Overall, HR HPV prevalence was 9.3% including 1.6% of HPV-16 and 0.4% of HPV-18. Of all 270 HPV positive samples, 211 (78.1% were HR-HPV non 16/18; 47 (17.4%) were HPV-16 and 12 (4.4%) were HPV-18. The prevalence of HPV infection was similar in all age groups, although a higher rate was observed in women age 31-40 years. Among women with normal cytology, HR HPV positive were found in 6.7%. In abnormal cytology, HR HPV were found 46.7% in atypical squamous cells (ASC), 54.8% in low-grade squamous intraepithelial lesions (LSIL) and 80.0% in high-grade squamous intraepithelial lesions (HSIL). HPV-16 was detected in 8.6%, 6.4% and 12.0% of ASC, LSIL and HSIL, respectively. The results of this study provide baseline information on the HPV type distribution, which may be useful for clinicians to decide who should be monitored or treated more aggressively.

Abstract
Most cervical cancers are caused by 15 high-risk (HR) and three probable high-risk (pHR) oncogenic types of human papillomavirus (HPV). However, current commercial HR HPV screening test products do not include pHR HPV genotypes. Recently, PapilloScreen has been developed to detect the 15 HR and three pHR HPV types. In this study, we evaluated the concordance levels and clinical performance of Hybrid Capture 2 (HC2), PapilloScreen, and a PCR sequencing assay in detecting HR and pHR HPV. The PapilloScreen (96.8 %) and PCR sequencing assay (96.8 %) demonstrated higher sensitivity than HC2 (80.7 %) for detecting HR and pHR HPV. The three assays showed similar specificities and positive or negative predictive values. The concordance levels were 86.5 % (κ = 0.68) and 86.5 % (κ = 0.67) between HC2 and PapilloScreen and between HC2 and PCR sequencing, respectively. A near-perfect concordance was observed between PapilloScreen and PCR sequencing (97.8 %, κ = 0.95). Overall, the agreement between the three assays suggests that the results obtained by the HC2 assay are more often discordant (12.6 %) than the PCR-based tests. In conclusion, PapilloScreen is highly sensitive for detecting high-grade CIN or cervical cancer. The PapilloScreen assay should be considered an accurate and sensitive method for detecting HR and pHR HPV infections and an epidemiological tool for prevalence studies as well as early diagnosis and intervention in HR and pHR HPV infections.

Abstract
Human papillomavirus (HPV) infection including sub-strain identification was studied in patients with squamous cell cervical cancer (SCCA) in Northeastern Thailand. Subjects were 90 cases of SCCA and 100 healthy controls. Prevalence of high-risk group of HPV infection in the controls and the SCCA patients were 13.0% and 86.7%, respectively. The HPV infection significantly increased the risk for cervical cancer 43.5-fold (95% confidential interval: 17.5-110.6; P <0.00001). Among HPV carrier patients with SCCA (n = 78), HPV-16 was also prominent (70.5%) followed by HPV-18 (23.1%). There was no statistical difference in the subtype distribution between the SCCA and the control groups. There was no significant association between genotype distribution of the p53 codon 72 polymorphism and HPV infection. HPV infection was confirmed as a critical risk factor for cervical cancer development in Northeast Thailand. Since polymorphism of the p53 itself as well as in combination with HPV infection may not be a genetic risk for cervical cancer, much attention should be paid to other risk factors such as sexual behavior and smoking.

Abstract
OBJECTIVE To determine the distribution of human papillomavirus (HPV) genotypes in cervical adenocarcinoma in Thailand and to evaluate the clinicopathologic characteristics associated with common HPV genotypes. METHODS Formalin-fixed, paraffin-embedded tissues from 150 patients with adenocarcinoma were collected from 4 areas of Thailand. Infection with HPV was detected by nested polymerase chain reaction (PCR) with primers MY09/11 and GP5+/6+. Genotyping was performed using a linear array assay, followed by type-specific PCR targeting the E6/E7 regions of HPV-16, HPV-18, and HPV-52 if the linear array test was negative. RESULTS Human papillomavirus DNA was detected in 145 (97%) adenocarcinomas (132 single infections; 11 multiple infections; 2 tumors with undetermined HPV type). Genotype 18 was most common (66%), followed by HPV-16 (30%) and HPV-45 (3%). Infection with only HPV-16 and/or HPV-18 accounted for 88% of the HPV-positive tumors. Patients with HPV-18 infection had a younger age (P=0.009) and higher tumor grade (P<0.001) than patients with HPV-16 infection. CONCLUSION The HPV detection rate in cervical adenocarcinomas in Thailand is high. The predominant genotype is HPV-18, being twice as common as HPV-16. Genotype variations are associated with patient age and tumor grade. Vaccination against HPV-16/HPV-18 might prevent almost 90% of adenocarcinomas.

Abstract
Production of matrix metalloproteinases (MMPs) for degradation of extracellular matrix is a vital step in cancer metastasis. We investigated the effects of HPV16 oncoproteins (16E6, 16E6*I and 16E7), either individually or combined, on the transcription of 7 MMPs implicated in cervical cancer invasiveness. The levels of 7 MMPs reported to be increased in cervical cancer were determined in C33A stably expressing different HPV16 oncoproteins using quantitative RT-PCR and compared with invasion ability of cell lines using in vitro invasion and wound healing assays. Overexpression of MMP-2 and MT1-MMP was detected in HPV16E6E7 expressing cells which correlated with increased cell invasion. Combination of HPV oncoproteins always showed greater effects than its individual form. Inhibition of cell invasion using a specific MMP-2 inhibitor, OA-Hy, and anti-MT1-MMP antibody confirmed that invasion in these cells was dependent on both MMP-2 and MT1-MMP expression. Depletion of HPV16E6E7 by shRNA-mediated knock-down experiments resulted in decreased MMP-2 and MT1-MMP expression levels as well as reduced invasion ability which strongly suggested specific effects of HPV oncoproteins on both MMPs and on cell invasion. Immunohistochemistry study in invasive cervical cancers confirmed the enhanced in vivo expression of these two MMPs in HPV16-infected cells. In addition, possible sites required by HPV16E6E7 on the MMP-2 and MT1-MMP promoters were investigated and PEA3 (at -552/-540 for MMP-2, -303 for MT1-MMP) and Sp1 (at -91 for MMP-2, -102 for MT1-MMP) binding sites were shown to be essential for mediating their transactivation activity. In conclusion, our study demonstrated that HPV16E6 and E7 oncoproteins cooperate in promoting cervical cancer invasiveness by specifically upregulating MMP-2 and MT1-MMP transcription in a similar manner.

Abstract
As knowledge of regional human papillomavirus (HPV) type distribution is essential for the optimization of prevention strategies, this study was carried out to explore the prevalence and type distribution of high-risk HPV in a screening population across Greece. Cervical samples were collected by local physicians and nurses in hospitals and health centers across the country from 4139 women attending for cervical cancer screening. High-risk HPV-DNA was detected by using Hybrid Capture-2 (HC2) and positive samples with adequate cellular content were further typed by restriction fragment length polymorphism-polymerase chain reaction. Almost six percent (5.9%) of women tested positive in HC2. The most common type was HPV16 (1.4% in the whole sample and 32.4% of the typed samples), followed by HPV53 (0.6 and 14.0%, respectively), HPV31 (0.6 and 12.9%, respectively), HPV35 (0.5 and 12.3%, respectively), HPV51 (0.4 and 7.8%, respectively), HPV18 (0.3 and 7.3%, respectively) and 22 more types. Almost 15% of the typed samples showed a coinfection with two HPV types and 2.1% with three types. There was a bimodal distribution by age, with the highest peak in women 20-29 years old and a lower peak in women 50-59 years old. Apart from the types originally included in HC2 cocktail, PCR analysis identified 15 more types (HPV6, HPV11, HPV34, HPV37, HPV38, HPV42, HPV53, HPV54, HPV55, HPV61, HPV62, HPV66, HPV73, HPV82, HPV83). Eleven percent of HC2-positive results arose from single-type infections with HPV53 (10%) and HPV66 (1%), which are potentially high-risk types. In conclusion, HPV16 is the most common type in the largest Greek screening sample used to date and, together with its related types, accounts for more than half of high-risk HPV infections. Approximately 10% of positive HC2 results arise from HPV53, which is not normally detected by the test, but may be clinically significant.

Abstract
BackgroundPersistent infection with high-risk (HR) human papillomavirus (HPV) is a well-recognized cause of cervical cancer, but little is known about the situation in Laos. The aims of the study were to determine the prevalence of HR-HPV among Lao women and to evaluate the use of a filter paper card (FTA Elute Micro Card) for collection of cervical cells in the humid tropical climate.MethodsThis is a cross-sectional study including 1922 women from 3 provinces in Laos. During a gynecological examination, cervical cells were collected and applied to the FTA card followed by HPV typing using a real-time polymerase chain reaction (PCR)-based assay.ResultsOverall, 213 of the 1922 women were positive for HR-HPV (11%). The most common type was the group HPV33/52/58 (3%), followed by the single type 16 (2%) and the group 18/45 (1%), respectively. Only 11 cards (0.6%) did not contain a sufficient amount of genomic DNA for polymerase chain reaction–based analysis.ConclusionsThe prevalence of HR-HPV infections in Laos is similar to other Asian countries, and 40% of the women with an HR-HPV infection will be target of the present HPV vaccines. The FTA card is suitable for collection of cervical cells for HR-HPV typing in tropical conditions. This information is important for planning and establishing primary and secondary prevention of cervical cancer in Laos.

Abstract
Little is known about the prevalence and seroprevalence of low-risk human papillomavirus (HPV) and the risk factors for HPV infection in Korean women. We determined the prevalence of low-risk HPV among 902 women aged 20-59 yr and the seroprevalence of low-risk HPV subtypes 6 and 11 among 1,094 women aged 9-59 yr in the general population. Genital low-risk HPV DNA was assessed by liquid hybridization and polymerase chain reaction. Antibody titers against HPV 6 and 11 were measured by a multiplexed competitive luminex technique. The prevalence of genital low-risk HPV was 4.9%. It reached its highest peak of 10.3% at 20-29 yr of age and a second peak of 3.2% at 50-59 yr of age. The seroprevalence of HPV 6 or 11 was 9.4%. It reached its highest peak of 12.7% at 25-29 yr of age and a second peak of 12.3% at 50-59 yr of age. In multivariable analysis, the number of lifetime sexual partners and past history of sexually transmitted diseases were associated with the seroprevalence but not prevalence of HPV. It is suggested that younger women should receive prophylactic HPV vaccination before they become sexually active and exposed to HPV in their 20s. This study provides baseline data for developing HPV vaccination programs and monitoring vaccine efficacy in Korea.

Abstract
Background and ObjectiveCervical cancer is the second most common female genital cancer worldwide. There is strong epidemiological and molecular evidence indicating that human papillomavirus (HPV) infection is a necessary event in the development of cervical intraepithelial lesion and subsequent invasive carcinoma. The aim of this study was to investigate the HPV genotype distribution and prevalence in cervical cancer of Thai women.Materials and MethodsOne hundred fifty-five cervical cancer specimens were enrolled in this study. The HPV genotypes were determined by means of the combined use of a line probe assay (INNO-LiPA) and DNA chip methods.ResultsOf the overall prevalence of HPV in the study group, 83.2% and 11.6% of the cases had single and multiple genotype infections, respectively. The most prevalent genotypes were HPV 16 (51%), followed by HPV 18 (20%), HPV 52 (10.3%), HPV 58 (5.8%), and HPV 33 (4.5%). All HPV genotypes found in this study could be classified as 13 high-risk HPV, 2 low-risk HPV, and 2 additional types. Of the specimens, 94.8% had at least one high-risk HPV genotype infection.ConclusionAs for the potential benefits of commercially available prophylactic vaccines to prevent HPV infection in Thailand, both vaccines (bivalent and quadrivalent) can protect from HPV-related cervical cancer in only approximately 71%. Therefore, screening programs such as routine Papanicolaou test, cytology, and HPV DNA detection are still essential for cervical cancer prevention. Moreover, future generations of HPV vaccines should also include the other most common genotypes and decrease the severe adverse effects reported at the present time.

Abstract
BACKGROUND Human papillomavirus (HPV) seroprevalence data have not previously been reported for different geographical regions of China. This study investigated the cross-sectional seroprevalence of antibodies to HPV 6, 11, 16, and 18 virus-like particles in Chinese women. METHODS Population-based samples of women were enrolled from 2006 to 2007 in 3 rural and 2 urban areas of China. Each consenting woman completed a questionnaire and provided a blood sample. Serum antibodies were detected using a competitive Luminex immunoassay that measures antibodies to type-specific, neutralizing epitopes on the virus-like particles. RESULTS A total of 4,731 women (median age 35, age range 14-54) were included, of which 4,211 were sexually active women (median age 37) and 520 virgins (median age 18). Low risk HPV 6 was the most common serotype detected (7.3%), followed by HPV 16 (5.6%), HPV 11 (2.9%), and HPV 18 (1.9%). Overall HPV seroprevalence to any type was significantly higher among sexually active women (15.8%) than virgins (2.5%) (P = 0.005). Overall seroprevalence among sexually active women gradually increased with age. Women from rural regions had significantly lower overall seroprevalence (Odds Ratio (OR) = 0.7; 95% CI: 0.6-0.9, versus metropolitan regions, P < 0.001). With increasing number of sexual partners, women were at higher risk of seropositivity of any type (OR = 2.6; 95% CI: 1.7-3.9 for > = 4 partners versus 1 partner, P < 0.001). Wives were at higher risk of seropositivity for HPV 16/18/6/11 when reporting having a husband who had an extramarital sexual relationship (OR = 2.0; 95% CI: 1.6-2.5, versus those whose husbands having no such relationship, P < 0.001). There was a strong association between HPV 16 seropositivity and presence of high-grade cervical lesions (OR = 6.5; 95% CI: 3.7-11.4, versus normal cervix, P < 0.001). CONCLUSIONS HPV seroprevalence differed significantly by age, geography, and sexual behavior within China, which all should be considered when implementing an optimal prophylactic HPV vaccination program in China.

Abstract
High-risk (HR) human papillomavirus (HPV) prevalence has been shown to correlate well with cervical cancer incidence rates. Our study aimed to estimate the prevalence of HR-HPV and cervical intraepithelial neoplasia (CIN) in China and indirectly informs on the cervical cancer burden in the country. A total of 30,207 women from 17 population-based studies throughout China were included. All women received HPV DNA testing (HC2, Qiagen, Gaithersburg, MD), visual inspection with acetic acid and liquid-based cytology. Women positive for any test received colposcopy-directed or four-quadrant biopsies. A total of 29,579 women had HR-HPV testing results, of whom 28,761 had biopsy confirmed (9,019, 31.4%) or assumed (19,742, 68.6%) final diagnosis. Overall crude HR-HPV prevalence was 17.7%. HR-HPV prevalence was similar in rural and urban areas but showed dips in different age groups: at age 25-29 (11.3%) in rural and at age 35-39 (11.3%) in urban women. In rural and urban women, age-standardized CIN2 prevalence was 1.5% [95% confidence interval (CI): 1.4-1.6%] and 0.7% (95% CI: 0.7-0.8%) and CIN3+ prevalence was 1.2% (95% CI: 1.2-1.3%) and 0.6% (95% CI: 0.5-0.7%), respectively. Prevalence of CIN3+ as a percentage of either all women or HR-HPV-positive women steadily increased with age, peaking in 45- to 49-year-old women. High prevalence of HR-HPV and CIN3+ was detected in both rural and urban China. The steady rise of CIN3+ up to the age group of 45-49 is attributable to lack of lesion removal through screening. Our findings document the inadequacy of current screening in China while indirectly raising the possibility that the cervical cancer burden in China is underreported.

Abstract
To optimize HPV vaccination implementation at the population-level in China, data are needed on age-specific HPV 16, 18, 6 and 11 prevalence. This cross-sectional, population-based study evaluated the age- and type-specific HPV 16, 18, 6 and 11 prevalence of DNA and serum antibodies among women in China. From July 2006 to April 2007, 17-54 year old women from three rural provinces (Xinjiang, Shanxi and Henan) and two cities (Beijing and Shanghai) provided cervical exfoliated cells for HPV DNA and liquid-based cervical cytology (SurePath). High- and low-risk HPV types were detected with HC-II (Qiagen), with genotyping of HPV-positive samples using Linear Array (Roche). HPV 16, 18, 6 and 11 serum antibodies were detected using a Luminex-based, competitive immunoassay (Merck). A total of 4,206 women with DNA and serum antibody results were included. HPV 16 DNA prevalence peaked in women aged 30-34 (4.2%) and 45-49 yr (3.8%), while HPV 18 DNA prevalence peaked at ages 40-44 yr (1.3%). Most women were dually DNA and serum antibody negative: HPV 16 (92.2%), 18 (97.2%), HPV 16 and 18 (90.2%), 6 (92.0%), 11 (96.6%), 6 and 11(89.9%) and HPV 16, 18, 6 and 11 (82.5%). Future national HPV vaccination programs in China should target younger women due to increased exposure to HPV types 16, 18, 6 and 11 with increasing age. Cumulative exposure of HPV may be underreported in this population, as cross-sectional data do not accurately reflect exposure to HPV infections over time.
