Impact of HPV molecular testing with partial genotyping as a feasibility study in cervical cancer community screening program in South India. J Med Virol 2023; 95:e28715. [PMID: 37185837 DOI: 10.1002/jmv.28715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 03/08/2023] [Accepted: 03/29/2023] [Indexed: 05/17/2023]
Abstract
Cervical cancer can be eradicated by 2030 by the implementation of a global strategy involving the vaccination of young girls against human papillomavirus (HPV), screening 70% of women in 30-69 years of age and treating 90% of the women with precancerous lesions. For a country with a large population like India, all the three strategies can be a challenge. There is a need for implementation of a high throughput technology that can be scalable. Cobas 4800, a multiplexed assay based on quantitative polymerase chain reaction technology, identifies HPV 16 and HPV 18 along with the concurrent detection of 12 pooled other high-risk HPV infections. This technology was used to test 10 375 women from the South Indian community for the first time as a feasibility program. Upon testing, high-risk HPV was found in 595 (5.73%) women. A total of 127 women (1.2%) were found to be infected with HPV 16, 36 women (0.34%) with HPV 18 and 382 women (3.68%) with the 12 pooled high-risk HPV and multiple mixed infections were found in 50 women (0.48%). It was observed that there was a high prevalence of high-risk HPV in younger women, 30-40 years of age and a second peak was observed at 46-50 years of age. The second peak had higher mixed infections in the 46-50 years of age and this association was statistically significant. We found that 24/50 (48%) of the multiple mixed high-risk HPV infections were in the age group 46-50 years. The current study is the first attempt from India, on a completely automated platform using Cobas 4800 HPV test in a community screening program. This study shows HPV 16 and HPV 18 infections, when differentiated, can be valuable for risk stratification in community screening program. Women in the perimenopausal age (46-50yrs) showed a higher prevalence of multiple mixed infections, signifying a higher risk.

Abstract
PURPOSE Prevalence of cervical high-risk human papillomavirus (hrHPV) infection varies greatly. Data on distribution of hrHPV infection constitute important evidence for decision-making when implementing HPV testing into cervical cancer screening programs. We estimate the prevalence of cervical hrHPV infection in a large sample of women in a middle-income country and explore variation by age, community marginalization and region in women using public cervical cancer screening services. METHODS Records covering 2010-2017 from a registry of hrHPV test results (Hybrid Capture 2 and polymerase chain reaction) in 2,737,022 women 35-64 years were analyzed. In this observational study, 32 states were categorized into five geographical regions and classified by degree of marginalization. We stratified by test type and estimated crude and adjusted prevalence and rate ratios and used Poisson models and joinpoint regression analysis. RESULTS Prevalence was higher in women 35-39 years, at 10.4% (95% CI 10.3-10.5) and women 60-64 years, at 10.1% (95% CI 10.0-10.3). Prevalence was higher in the southeast, at 10.5% (95% CI 10.4-10.6). Women living in less marginalized areas had a significantly higher prevalence, at 10.3% (95% CI 10.2-10.4) compared to those in highly marginalized areas, at 8.7% (95% CI 8.5-8.7). HPV16 infection was detected in 0.92% (2,293/23,854) of women and HPV18 infection was detected in 0.39% (978/23,854) of women. CONCLUSION Understanding the distribution of HPV prevalence has value as evidence for developing policy in order to improve cervical cancer screening strategies. These results will constitute evidence to allow decision makers to better choose where to focus those resources that they do have.

Abstract
Viruses are the most abundant and genetically diverse entities on the planet, infect all life forms and have evolved with their hosts. To date, 263 viral species have been identified that infect humans, of which only seven are considered type I oncogenic. Human papillomavirus (HPV) is the main virus associated with cancer and is responsible for practically all cases of cervical carcinoma. Screening tests for early detection have been available since the 1960s. Undoubtedly, the entailment between knowledge of HPV biology and the natural history of cervical cancer has contributed to the significant advances that have been made for its prevention since the 21st century, with the development of prophylactic vaccines and improved screening strategies. Therefore, it is possible to eradicate invasive cervical cancer as a worldwide public health problem, as proposed by the WHO with the 90-70-90 initiative based on vaccination coverage, screening, and treatment, respectively. In addition, the emerging knowledge of viral biology generates opportunities that will contribute to strengthening prevention and treatment strategies in HPV-associated neoplasms.

Abstract
Infections caused by the human immunodeficiency virus (HIV) and human papillomavirus (HPV) cause thousands of deaths worldwide each year. So far, there has been no consensus on whether there is a direct relationship between the incidence of neoplasms and the immunosuppression caused by HIV that could help understand if coinfection increases the likelihood of cervical cancer. The objective of the study was to identify the presence of genetic variants of HPV in a group of HIV-positive women and their possible association with cervical cancer. Cervical samples were taken from HIV-positive patients for cytological analysis to identify the HPV genotype by polymerase chain reaction (PCR) and sequencing. The most prevalent L1 capsid protein mutations in the HPV genotype were analyzed in silico. Various types of HPV were identified, both high-risk (HR) and low-risk (LR). The most prevalent genotype was HPV51. Analysis of the L1 gene sequences of HPV51 isolates showed nucleotide variations. Of the samples analyzed in Puebla, Mexico, HPV51 had the highest incidence (17.5%, 7/40). Different mutations, which could be used as population markers, were detected in this area, and they have not been reported in the L1 databases for HPV51 in Mexico. Genotypes 6, 14, 86, 87, 89, and 91, not detected or reported in samples from patients with HPV in Mexico, were also identified. Data from the population analyzed suggest no direct relationship between HIV immunosuppression and cervical cancer, regardless of the high- or low-risk HPV genotype. Furthermore, it is possible to develop regional population markers for the detection of HPV based on the mutations that occur in the sequence of nucleotides analyzed.

Abstract
Human papillomavirus is the most common sexually transmitted infection in the world and had been linked to both anogenital and oropharyngeal cancers. It causes nearly 100% of cervical cancers and an increasing portion of oropharyngeal cancers. The geographical burden of cervical HPV infection and associated cancers is not uniform and is mainly found in low middle income countries in South America, Africa, and Asia. However, HPV-positive oropharyngeal cancer is rapidly becoming more prevalent in high middle income countries. With the development of vaccines which prevent HPV infection, the World Health Organization has designated the extirpation of HPV and its associated cancers a priority. Countries that have implemented adequate vaccine programs have shown a decrease in HPV prevalence. Understanding the epidemiology of HPV and its associated cancers is fundamental in improving vaccine programs and other health programs.

Tobacco use and its association with HPV infection in normal uterine cervix: A study from a Sustainable Development Goals perspective. Tob Induc Dis 2021; 19:64. [PMID: 34413719 PMCID: PMC8340940 DOI: 10.18332/tid/140093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 06/22/2021] [Accepted: 07/08/2021] [Indexed: 11/24/2022] Open
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.

Incidence of cervical intraepithelial lesions and human papilloma virus infection in female renal transplant recipients. Transpl Infect Dis 2021; 23:e13622. [PMID: 33877726 DOI: 10.1111/tid.13622] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 03/03/2021] [Accepted: 04/05/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Female renal transplant recipients (RTR) are at high risk of human papillomavirus (HPV)-related anogenital premalignancies and cancer. The aim of this study was to estimate the incidence of cervical intraepithelial lesions (IL) and HPV infection, and their associated factors, in Mexican RTR. METHODS This is a prospective cohort study conducted between January 2011 and December 2017. Demographic, clinical, and gynecological data were collected using a previously designed questionnaire. Gynecological examination, cervical cytology, and detection of high- and low-risk HPV DNA were undertaken prior to and after the renal transplant (RT). Colposcopically guided biopsies were obtained from patients who presented high grade squamous intraepithelial lesions (HSIL) during the follow-up period. Diagnoses were established according to the Bethesda system. RESULTS Among 130 RTR, 62 were eligible for our study. The overall incidence of IL was 17.7% (95% CI, 8% to 27%), (11/62 patients), at 25.6 ± 10.7 months post-RT. Nine out of the eleven affected patients had low-grade squamous intraepithelial lesions (81.8%) and only two had HSIL (18.2%). The incidence of HPV infection, determined in a subgroup of 30 RTR, was 53.3% (95% CI, 35% to 71%), (16 out of 30 patients), at 18.3 ± 8.9 months post-RT. High-risk HPV genotypes were present in 62.5% of HPV positive cases (10/16). In 11 patients (36.6%), HPV infection was not associated to IL. CONCLUSIONS HPV infection and cervical IL are common in the early posttransplant period. Our findings support the need of screening for cervical cancer to detect precancerous changes in RTR and the need of strengthening the knowledge of medical personnel on this issue.

Abstract
According to their oncogenic properties, Human Papillomaviruses (HPVs) are classified into two types: Low-Risk (LR-HPVs) and High-Risk Human Papillomaviruses (HR-HPVs). The immune system naturally controls the majority of HPV infections; however, when the HR-HPV infection is persistent, the risk of developing cervical cancer increases. Previous studies indicate that multiple-infection or coinfection with HR-HPV occurs frequently and can potentiate the development of cervical lesions. This study aimed to establish the HPV coinfection rate in squamous intraepithelial lesions from Mexican patients. For HPV detection, we performed PCR on 55 cervical lesions diagnosed by colposcopy. We detected the presence of HPV infection in 87.27% (48/55) of the lesions; interestingly, HPV coinfection was observed in 70.83% (34/48) of these samples. We also evaluated HPV infection in adjacent areas without morphological changes from 25 samples. The results showed that 80% (20/25) of these were HPV-positive and, curiously, all presented HPV-16 infection. In conclusion, our results revealed a high prevalence of HPV coinfection in cervical lesions in Mexican patients, and these results contribute to future research focused on the role that HPV coinfection plays in the development of cervical cancer.

Abstract
IMPACT STATEMENT We are submitting data regarding the prevalence and type distribution of the HPV infection and the risk factors associated with it, which may provide a valuable reference to reinforce screening strategies, and to maintain HPV genotype surveillance in Mexico. We discuss the overall prevalence of HPV infection as detected in normal cytological samples stratified by age, different types of infection, and oncogenic capacity. One of the most important findings was that common HPV genotypes detected in healthy women were the genotype numbers: 6, 31, 16, and 56, likewise, smoking and having a history of more than three sexual partners over their lifetime, represented the main risk factors in this study. Furthermore, we found a low frequency of cytological abnormalities and CIN 1-3 in women with HR-HPV.

Baseline prevalence and type distribution of Human papillomavirus in sexually active non-vaccinated adolescent girls from Argentina. Rev Argent Microbiol 2020; 53:11-19. [PMID: 32788072 DOI: 10.1016/j.ram.2020.06.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Revised: 05/11/2020] [Accepted: 06/17/2020] [Indexed: 10/23/2022] Open
Abstract
In 2011, Argentina launched a government-funded national Human papillomavirus (HPV) immunization program incorporating a bivalent HPV vaccine, with a 0-1-6-month schedule, for girls 11 years of age, born after January 2000. Monitoring the changes of HPV infection prevalence among young women has been proposed as an endpoint for early assessment of HPV vaccination programs. However, the data on HPV prevalence at young ages are very limited. The aim of this work was to determine the prevalence of HPV infection and type-specific distribution in sexually active 15-17-year-old non-vaccinated girls. Cervical samples from 1073 adolescents were collected for HPV detection and genotyping using the BSGP5+/GP6+PCR-reverse line blot (RLB) assay. Out of 957 specimens analyzed, 56.3% were positive for any HPV type; 42.2% harbored at least one high-risk HPV (HR-HPV) type and 30.8% low-risk HPV (LR-HPV) types. Multiple and single infections were identified in 36.3% and 20.0% of the samples respectively. The 6 most common HR-HPV types were HPV16 (11.1%), HPV52 (10.8%), HPV56 (8.3%), HPV51 (7.4%), HPV58 (7.3%) and HPV31 (7.1%). The prevalence of HR-HPV-16/18 was 15.2%. In conclusion, results confirm that HPV (particularly HR-types) are very common among sexually active adolescents, and prevalence rises quickly after their sexual debut. Our HPV type-specific prevalence baseline may be used to monitor post-vaccinal longitudinal changes in Argentina.

Abstract
Objectives The natural history of human papillomavirus (HPV) infection has been studied extensively in young women; this study investigated HPV infection in adult women. Methods Data from 3817 women aged 24–45 years in a global trial of the 4-valent HPV (6/11/16/18) vaccine were used to calculate prevalence of anogenital infections containing 9-valent (9v) HPV vaccine types (6/11/16/18/31/33/45/52/58) and five non-vaccine types (35/39/51/56/59). Incidence of infections and persistent infections was estimated for 989 placebo recipients naive to all 14 HPV types at baseline. Age-adjusted hazard ratios were calculated for various sociodemographic factors. Results Prevalence of anogenital infection was highest in France at 29.2% (9vHPV types) and 21.7% (non-vaccine types) and lowest in the Philippines at 7.6% (9vHPV types) and 5.1% (non-vaccine types). Overall, HPV incidence (per 100 person-years) was 5.2 (9vHPV types) and 4.7 (non-vaccine types), and incidence of persistent infection was 2.7 (9vHPV types) and 2.1 (non-vaccine types). Factors associated with new HPV infections included younger age, younger age at first intercourse, being single, current use of tobacco, and higher number of past and recent sex partners. Conclusions Because mid-adult women acquire new HPV infections, administration of the 9vHPV vaccine could reduce HPV-related morbidity and mortality in this population. Prevalence of HPV infection in mid-adult women varies by country for age. Mid-adult women still acquire new HPV infections, including persistent infections. Risk factors for acquiring new HPV infections are similar in mid-adult and young women.

Abstract
Our aim was to review the major contributions of studies conducted in different Latin American (LA) countries to the field of human papillomavirus (HPV) epidemiology, natural history, risk of disease, and prevention strategies, mainly in the uterine cervix. Although cytological screening is established in several countries in LA, incidence and mortality rates from cervical cancer (CC) are still extremely high. Finally, data from large cohort studies conducted in LA countries provided seminal data to propose primary and secondary prevention modalities: the HPV vaccine has been introduced in the national immunization programs of several LA countries and multiple screening experiences using HPV testing are under evaluation in the region.

Abstract
BACKGROUND Cervical cancer is the second cause leading of malignancy-related death among Mexican women. The present study determined the population-based prevalence of high risk Human Papillomavirus (HR-HPV) infection and associated cofactors in female beneficiaries of the Institute of Security and Social Services for State Workers (ISSSTE) attending the Program for HPV Screening and Early Detection of Cervical Cancer and registered in the Women's Cancer Detection System (SIDECAM). METHODS In a cross-sectional study, cervical samples from 115,651 female users of the program for HPV screening and early detection of cervical cancer recruited in 23 ISSSTE care centers were analyzed for HR-HPV. Logistic regression analyses, adjusting for potential confounders, were performed to determine the association of HR-HPV infection with sexual health and behavior variables and with positivity to cervical premalignant lesions by cytology. RESULTS The overall prevalence of HR-HPV infection among female ISSSTE beneficiaries in the 2013-2015 period was 13%. A bivariate analysis of relevant variables for HR-HPV infection showed a statistically significant association for age, number of sexual partners, use of hormonal contraceptives and smoking. A statistical association was found between infection by HR-HPV with the use of hormonal contraceptives, number of sexual partners and smoking and association of HPV 16 and other non-16/18 HR-HPV infection with number of lifetime sexual partners and tobacco use adjusted for age, history of hormonal contraception, number of sexual partners and tobacco use with the exception of exposition variable itself. Similarly, an association was found between HR-HPV infection, regardless of the virus genotype, with positivity to cervical premalignant lesions adjusted for age, number of lifetime sexual partners, history of hormonal contraception and tobacco use. CONCLUSIONS HR-HPV prevalence in female ISSSTE Women's Cancer Program users is similar to the population-based prevalence previously reported in Mexican women without cervical alterations. The ISSSTE robust screening and early detection program, based on cytology studies and HPV co-testing, allows us to know the prevalence of HR-HPV infection among female users of the service.

Abstract
In Mexico, HPV vaccines available immunize against genotypes 16/18 and 16/18/6/11; however, there is limited surveillance about carcinogenic subtypes in different states of the country that allow evaluating the effectiveness of vaccination and cervical cancer screening programs. Here, we report the regional and age-specific prevalence of 14 hr-HPV genotypes as well as their prevalence in abnormal cytology (from ASCUS to cervical cancer) among Mexican women which were undergoing from cervical cancer screening in the Salud Digna clinics in 20 states of the country. This study includes women with social security from the majority of public health institutions (IMSS, ISSSTE, SEMAR, and PEMEX), and women without social security. For cervical cancer screening, we used the SurePath liquid-based cytology and the BD Onclarity HPV Assay. From December 1, 2016, to August 2, 2018, the hr-HPV prevalence among 60,135 women was 24.78%, the most prevalent types were HPV 16 (4.13%), HPV 31 (4.12%) and HPV 51 (3.39%), while HPV 18 (1.70%) was less prevalent among infected women. Interestingly, the genotypes not covered by current vaccines in Mexico were commonly found in precancerous lesions, evidencing their carcinogenic potential, so it is necessary to increase their surveillance and inclusion in cervical cancer screening triage.

Abstract
BACKGROUND Cervical cancer (CC) is one of the leading causes of cancer mortality among women from Paraguay, with high incidence and mortality rates (31.2 and 16 per 100 000 women, respectively). Although the risk factors associated with high-risk human papillomavirus (hrHPV) infection and preneoplastic cervical lesions are widely studied, population-based characteristics of particular settings may influence the feasibility of HPV-based CC screening implementation. This study aimed to explore factors associated with hrHPV infection and high-grade cervical neoplasia in hrHPV-positive (hrHPV+) women from Paraguay. METHODS A total of 5677 women aged 30-64 years from the Central Department of Paraguay were screened with HPV test (Hybrid Capture 2) and Pap smear. Sociodemographic and risk factor interviews were conducted. hrHPV+ women were referred to colposcopy and women with an abnormal colposcopy had a biopsy taken. The outcomes recorded were the hrHPV status and the presence of high-grade cervical intraepithelial neoplasia or worse (CIN2+) among hrHPV+ women. Associations were investigated using multivariate logistic regressions. RESULTS hrHPV prevalence was 13.8% (95%CI 13.0-14.8). This value decreased with the age of women (p-trend<0.001) and increased with the lifetime number of sexual partners (p-trend<0.001) and number of previous female partners of their current male partner if women had had one lifetime sexual partner (p-trend<0.001), increasing from 3.06 (95%CI 0.073-20.9) if partners had had one previous female partner to 9.19 (95%CI 2.36-61.1) if they had had eight or more. In hrHPV+ women, CIN2+ prevalence was 10.7% (95%CI 8.58-13.2) and increased with time since the last Pap smear (p-trend<0.001) and with the increasing number of pregnancies (p-trend = 0.05). CONCLUSION In these settings, the sexual behavior of women and their male partners is associated with hrHPV infection. In hrHPV+ women, underscreening practices and multiple pregnancies are associated with CIN2+. This knowledge can contribute to public health policies for CC prevention and control in Paraguay.

Abstract
HPV is the most common sexually transmitted infection in the U.S., infecting both anogenital and oral sites. Nationally representative data are collected through the National Health and Nutrition Examination Survey (NHANES). However, changing designations of HPV genotypes as high or low risk and varying underlying populations as new results are reported have made direct comparison of results difficult. We reanalyzed HPV data from NHANES derived from self-collected cervicovaginal swabs (women ages 18-59, 2003-14), penile swabs (men ages 18-59, 2013-14), and oral rinses (men and women ages 18-69, 2009-14), using consistent populations and definitions across NHANES cycles. These data strengthen our understanding of age trends in HPV prevalence: cervicovaginal prevalence decreases with age, penile prevalence increases with age, and oral prevalence is bimodal but with an earlier first peak in women. There is strong evidence for reduced prevalence of vaccine genotypes (6, 11, 16, 18) in vaccinated men and women (ages 18-24) at both genital (RR 0.2 (0.1-0.3) in women and 0.7 (0.1-5.4) in men) and oral sites (RR 0.1 (0.0-1.3) in women; no infections detected in vaccinated men). A more complete picture of the burden of HPV in the U.S. is emerging, including evidence for reduced HPV genital and oral prevalence in vaccinated individuals.

Abstract
While sociodemographic predictors of cervical cancer (CC) are well understood, predictors of high-risk (HR) human papillomavirus (HPV) infection have not been fully elucidated. This study explored the HR-HPV infection positivity in relation to sociodemographic, sexual behavior characteristics and knowledge about HPV and CC prevention among women who visited the Arkhangelsk clinical maternity hospital named after Samoylova, Russia. This cross-sectional study was conducted in the city of Arkhangelsk, Northwest Russia. Women who consulted a gynecologist for any reason between 1 January 2015 and 30 April 2015 were residents of Arkhangelsk, 25-65 years of age were included. The Mann-Whitney and Pearson's χ2 tests were used. To determine the HR-HPV status, we used the Amplisens HPV-DNA test. We used a questionnaire to collect the information on sociodemographic factors. Logistic regression was applied. The prevalence of HR-HPV infection was 16.7% (n = 50). HR-HPV infection was more prevalent in younger women, cohabiting, nulliparae, smokers, having had over three sexual partners and early age of sexual debut. The odds of having a positive HR-HPV status increased by 25% with an annual decrease in the age of sexual debut. Moreover women with one child or more were less likely to have positive HR-HPV status.

Abstract
OBJECTIVE To asses the non-inferiority between two differ- ent vaccination schedules one month after the administration of the third dose. MATERIALS AND METHODS We evaluated the anti-HPV 16/18 antibody titers induced by quadrivalent HPV vaccine administered using two different schedules in girls 9 to 10-year-old girls: a traditional (0-2-6) and an alterna- tive (0-6-50). Blood samples were collected at month 7, 21 and 51. RESULTS The antibody geometric mean titer ratios one month after the application of the third dose -month 51 for the alternative and month 7 for the traditional- were 1.55 for HPV16 (95%CI, 1.15-2.08) and 1.53 for HPV18 (95%CI, 1.12-2.09). The seropositive rate was above 99% in both groups. CONCLUSIONS The application of an alternative 3-dose schedule in 9 to 10-year-old girls induces a non-inferior immune response compared to the standard one month after the last dose. Further research is needed to understand the minimal number of doses and their timing to provide the best coverage for HPV infection.

Abstract
OBJECTIVE To discuss cervical cancer (CC), Human PapillomaVirus (HPV),CC control program and propose alternatives for Chile. MATERIALS AND METHODS We analyzed the national program of CC 1966-2015 and the clinical CC guideline 2015-2020;HPV prevalence in women and in cases of CC; HPV infection and serology; the self-vaginal sample; the accuracy and cost-effectiveness of screening with HPV versus Papanicolaou,and triage options among HPV-AR positives. RESULTS 600 women die of CC each year in Chile, mainly from low resources. Papanicolaou coverage is <70%; Papanicolaou sensitivity is much lowerthan HPV test.Change from Papanicolaou to HPV test is cost-effective. Since 2015, girls under 13 have been vaccinated against HPV. CONCLUSIONS .There are the technical and economic conditions for a substantial improvement of CC in Chile: replacement of the Papanicolaou by HPV; screening every five years, with the option of self-sampling, and triage based on HPV 16/18 or Papanicolaou typing.

Association between HPV infection and prostate cancer in a Mexican population. Genet Mol Biol 2018; 41:781-789. [PMID: 30508006 PMCID: PMC6415601 DOI: 10.1590/1678-4685-gmb-2017-0331] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Accepted: 03/29/2018] [Indexed: 12/19/2022] Open
Abstract
The aim of this study was to evaluate the association between prostate cancer (PCa) and Human papillomavirus (HPV) infection in the Mexican population. We studied 356 paraffin-embedded tissues from unrelated Mexican men with PCa or benign prostatic hyperplasia (BPH), with the latter serving as control. HPV detection was performed by polymerase chain reaction (PCR) using universal primers, and viral genotypes were detected using sequencing or multiplex PCR. Light microscopy analyses enabled the identification of koilocytes in samples subsequently analyzed for HPV detection by in situ PCR and for p16-INK4A expression by immunohistochemistry. The results showed that high risk- (HR) HPVs were detected in 37/189 (19.6%) PCa specimens compared to 16/167 (9.6%) of BHP specimens (odds ratio 2.3; 95% CI= 1.2 to 4.3; p=0.01). These data suggest HR-HPV may play a role in PCa. HPV 52 and 58 were the most frequent genotypes (33 and 17%, respectively) detected in the population studied. Koilocytes were detected in all in situ PCR-HPV-positive samples, representing a pathognomonic feature of infection, and we observed the overexpression of p16-INK4A in HPV-positive samples compared to HPV-negative samples, indirectly suggesting the presence of HR-HPV E7 oncoprotein. These results suggest that HPV infection plays an important role in prostate cancer development.

Abstract
Human papillomavirus (HPV) is a DNA virus linked to mucosal and cutaneous carcinogenesis. More than 200 different HPV types exist. We carried out a transversal study to investigate the prevalence of HPV types in two regions of Mexico. A total of 724 genital and non-genital samples from women (F) and men (M) were studied; 241 (33%) from North-Eastern (NE) and 483 (66%) from South-Central (SC) Mexico. The overall prevalence was 87%. In genital lesions from females, the NE group showed a prevalence of HPV types 16 (37%), 6 (13%), 59 (6%), 11, 18 and 66 (5.4% each); and the SC group showed types 6 (17%), 16 (15%), 11 (14.5%), 18 (12%) and 53 (6%). In the genital lesions from males, NE group showed types 16 (38%), 6 (21%), 11 (13%) and 59 plus 31 (7.5%) and the SC group showed types 6 (25%), 11 (22%), 18 (17%) and 16 (11.5%). When the two regions were compared, a higher prevalence of low-risk HPV 6 and 11 was found in the SC region and of high-risk HPV 59, 31 and 66 (the latter can also be present in benign lesions) in the NE region. Our findings complement efforts to understand HPV demographics as a prerequisite to guide and assess the impact of preventive interventions.

Abstract
Background: Human papillomavirus (HPV) subtypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68 have been implicated in the development of cervical cancer (CC). These 13 high risk HPV types have been shown to be present in up to 99.7% of CC samples. In Mexico, this cancer is the leading cause of death from malignancy among women. The aim of this study was to determine the prevalence of different HPV genotypes and investigate epidemiological aspects associated with HPV infection in women from Cozumel. Material and methods: We performed an epidemiological, prospective and cross sectional study with 1,187 who accepted participation in a campaign of screening for CC, during the period 2014 to 2015. Data on epidemiological and socio-economic variables were obtained. Cervical cells were collected for detection of HPV DNA and typing of HPV-positive samples by Multiplex PCR, using a commercial kit for 16 viral genotypes. Results: The overall prevalence of HPV in women from Cozumel was 15.8 % (188/1,187), either single (13.6%) or multiple (2.19 %). The most common HPV types , in descending order of frequency, were 58 (24.5 %), 59 (13.3 %), 39 (12.2 %) and 66 (9.6 %). The most frequent high risk types were HPV-58 and -59 and of low risk HPV types the most common was HPV-6. Number of sexual partners (OR=4.78; 95% CI= 2.73-8.37; P=<0.0001) and age of first coitus (OR=0.51; 95% CI=0.32-0.81; P=<0.0011) were significantly associated with HPV infection. Conclusions: Our data indicate that the overall incidence of high risk HPV infection in Cozumel is low as compared to other studies worldwide, with a different profile of subtypes. However, as expected, risky sexual behavior was found associated with positive cases of HPV. These results highlight the need for establish strategies to prevent HPV acquisition and evaluate the impact of a vaccine application in the Cozumel population.

Abstract
Introduction Cervical cancer is a malignancy originating in the transformation zone of the cervix, most commonly in the squamous cells. It is the fourth most common cancer in women worldwide, and the third most common cause of female cancer death. Genital human papilloma viruses (HPV) are sexually transmitted and approximately 630 milion people worldwide are infected. More than 200 genotypes, subtypes and variants have been reported, 13-15 being oncogenic type, which could be responsible for cervical intraepithelial lesions (CIN) or cancer. Aim Aim of this study was to evaluate the prevalence of this infection and to identify specific types of human papiloma virus in cervical intraepithelial lesions and cervical cancer in Macedonian women. Material and methods The study was conducted at the University Clinic for Obstetrics and Gynecology, Skopje, Macedonia, in a period of four years. The study was performed on a cohort of 1895, 18 - 73 year old patients who during primary examination had already abnormal PAP smear test. Cervical cells were collected in the lithotomy gynecological position of the patient, using endocervical cytobrush and cotton-tipped swab, and both were placed in sterile test tube with phosphate buffered saline. Samples were stored at temperature of 2 - 8 °C and Human Pappiloma Virus (HPV) genotyping was analyzed within 7 days by multiple Polymerase Chain Reaction (PCR) methods. Results The mean age of enrolled women was 40,8 years±10.36 SD(minimum of 18 and maximum 73 years. Among the patients, the presence of HPV by using PCR was detected in 40,68 % (769 patients) and was highly associated with cervical abnormalities. The prevalence of HPV was highest (82,1%) in women aged 20-years or less and it decreased with age and was lowest (19,9%) among patients older than 50 years. The prevalence of oncogenic types of the virus was higher if the cytologic diagnosis is CIN 3/Carcinoma in situ (CIS). In these patients detection of high risk HPV was in 79,1% females with CIN 3 and 97,5 % in females with CIS. The lowest prevalence was detected in patients with atypical squamous cells of undetermined significance (ASCUS) (23,9%) and CIN 1-25 (6%). Results of HPV typing show that genotypes were found either single or multiple in both single and multiple infections. We have seen that HPV 16, 18 and 31 were the most common types detected among the patients from Macedonia. HPV 16 was present even in 52,1 % of women with CIS and in 41,2% in women with CIN 3. HPV type 31 ranked second in patients wit CIN1, CIN2, CIN3 but HPV 18 ranked second in patients with CIS with (12,8%). Surprisingly, patients with mixed infection had more low grade intraepithelial squamous lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL) then CIS. Conclusion Among Macedonian women, HPV 16, 31 and 18 were HPV types strongly associated with intraepithelial cervical lesions and cervical cancers. The prevalence of high risk HPV was highest in youngest women, but the risk was highest among patients with invasive cervical cancer (ICC). Surprisingly, patients with mixed infection had more LSIL and HSIL then CIS.

Abstract
Background Cervical cancer is the second most prevalent cancer among women of child-bearing age in Ethiopia. The aim of this study was to determine human papilloma virus (HPV) genotype distribution among HIV-negative women with normal and abnormal cervical cytology results. Methods We investigated a consecutive of 233 HIV-negative women between December 2008 and March 2009 presenting in a Tertiary Gynecology Referral Clinic in Ethiopia. Screening was done by Pap cytology and HPV detection and genotyping method was nested PCR (direct amplification with MY09/MY11 primers, followed by nested amplification with GP5/GP6 primers) and sequencing of the nested products. Sequencing of the non-purified nested PCR products was performed following re-amplification with Big dye terminator, using the GP6 primer. Results Of the 233 study participants, 92 (39.5%) had abnormal cytology. All women with abnormal cervical cytology had positive HPV DNA compared to only 48.9% of those presenting with normal cytology. Of these women, the frequency of high-risk (HR)-HPV was 83.2% and its prevalence in women with abnormal cervical cytology was significantly higher than those with normal cytology (92.4% vs. 71%, p < 0.0001). The most frequent genotypes identified were HPV16 (44.1%), followed by HPV35 and HPV45 (each 6.2%), HPV31 (4.4%), HPV56 (3.7%), HPV18 and HPV59 (each 3.1%), HPV58 (2.5%) and HPV39 (1.9%). While the most common HR-HPV infections among women with normal cytology were HPV16 (20.3%), followed by HPV35 (8.7%), HPV56 and HPV58 (each 5.8%), HPV18, HPV31 and HPV39 (each 4.4%), HPV45 (2.9%) and HPV59 and HPV68 (each 1.5%), the most common HR-HPV infections in women with abnormal cytology included HPV16 (62%), followed by HPV45 (8.7%), HPV 31, HPV35 and HPV59 (each 4.4%), and HPV18, HPV52 and HPV56 (each 2.2%). We also noted low prevalence of multiple HPV infections in women with normal or abnormal cytology. Multivariable logistic analysis showed that residing in rural area (OR 3.24, 95% CI: 1.13-9.30), being multipara (OR 7.35, 95% CI: 1.78-30.38) and having abnormal cervical cytology results (OR 6.75, 95% CI: 1.78-25.57) were all independently associated with HPV16 genotype. Conclusions Our study revealed a significant risk of infection with HR-HPV, in particular with HPV16 genotype, in women attending a referral center in Ethiopian women presenting with or without abnormal cervical cytology. Moreover, Pap smear cytology missed a significant proportion of women compared to those who were identified by PCR for HR-HPV infections. In addition, the PCR method we used was not suitable for sensitive detection of co-existent multiple infections. Data from the present study indicate that currently available HPV vaccines could prevent nearly 67% of all cervical cancer cases in women in Ethiopia.

Abstract
Objectives To identify factors associated with high-risk human papillomavirus (HPV) infection and high grade squamous intraepithelial lesion (HSIL) among a high-risk group of HPV-unvaccinated women in Montevideo. Methods Participants completed a questionnaire on socio-demographics, sexual behavior and gynecological history and received a gynecological examination. HPV DNA was detected by PCR using MY09/11 primers. Logistic regression analyses were performed to identify factors associated with high-risk HPV infection and HSIL. Results A total of 469 women with HPV DNA and cytological results completed the questionnaire. Among women older than 30 years, those with high number of sexual partners and regular housing conditions were more likely to be positive for high-risk HPV infection (adjusted OR: 2.94, 95%CI: 1.01–8.51 and 2.68, 95%CI: 1.01–7.21, respectively). A marginally non-statistically significant association between getting a HSIL and having a high number of sexual partners was also observed (adjusted OR: 3.22, 95%CI: 0.97–10.75). Conclusions In an era of development of new strategies for accelerating the reduction of cervical cancer incidence and mortality, our results may contribute to identify populations most susceptible to get benefit from broadening the scope for prevention of cervical cancer and could be used with other triage strategies.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-positive women have a high prevalence of human papillomavirus (HPV), and are infected with a broader range of HPV types than HIV-negative women. We aimed to determine the prevalence of cervical cytologic abnormalities, high-risk (HR)-HPV prevalence, type distribution according to the severity of cervical lesions and CD4 cell count and identify factors associated with HR-HPV infection among women living with HIV in Manaus, Amazonas. METHODS We enrolled 325 women living with HIV that attended an infectious diseases referral hospital. Each woman underwent a gynecological exam, cervical cytology, HR-HPV detection by Polymerase chain Reaction (PCR) using the BD Onclarity™ HPV Assay, colposcopy and biopsy, when necessary. We assessed the associations between potential risk factors and HR-HPV infection. RESULTS Overall, 299 (92.0%) women had a PCR result. The prevalence of HR-HPV- infection was 31.1%. The most prevalent HR-HPV types were: 56/59/66 (32.2%), 35/39/68 (28.0%), 52 (21.5%), 16 (19.4%), and 45 (12.9%). Among the women with HR-HPV infection (n = 93), 43.0% had multiple infections. Women with HPV infection showed higher prevalence of cervical abnormalities than that HPV-negative (LSIL: 22.6% vs. 1.5%; HSIL: 10.8% vs. 0.0%). The prevalence of HR-HPV among women with cytological abnormalities was 87.5% for LSIL and 100.0% for HSIL. Women with CD4 < 200 cell/mm3 showed the highest HR-HPV prevalence (59.3%) although this trend was not statistically significant (p-value = 0.62). The mean CD4 cell count decreased with increasing severity of cervical lesions (p-value = 0.001). The multivariable analysis showed that increasing age was associated with a decreased risk of HR-HPV infection with an adjusted prevalence odds ratio of 0.9 (95.0% CI: 0.9-1.0, p-value: 0.03) for each additional year. The only factor statistically significant associated with HR-HPV infection was CD4 cell count. CONCLUSIONS HR-HPV and abnormal cytology prevalence are high among women in the Amazonas. The low CD4 cell count was an important determinant of HPV infection and abnormal cytological findings. HPV quadrivalent vaccination used in Brazil might not offer protection for an important fraction of HPV-related disease burden in women living with HIV. This is partly explained by the high presence of non targeted vaccine HR-HPVs, such as the HPV genotype groups 56/59/66, 35/39/68 and individually HPV-52 and HPV-45, some of which contribute to high-grade lesion.

Abstract
BACKGROUND Cervical cancer prevention using cervical cytology is insufficiently sensitive, a significant proportion of HPV-infected women having normal cytology. The objective of the present study was to try to identify factors associated with abnormal cytology in HPV-infected women living in remote areas of French Guiana. METHODS A study was conducted in women aged 20-65 years having HPV infections confirmed by HPV DNA detection using the GREINER-BIO-ONE kit. In addition to HPV testing, cytology was performed and classified as normal or abnormal. Demographic and life history variables, and infecting genotypes were compared between the normal and abnormal cytology groups. RESULTS None of the demographic and life history variables were associated with cytology results. HPV genotype 53 was significantly associated with absence of cytological abnormalities whereas HPV 52, 58, 16 and perhaps 33 and 66 were independently associated with a greater risk of cytological abnormalities. When grouping HPV genotypes in different species, only species 9 (HPV 16, 31, 33, 35, 52, 58, 67) was significantly associated with abnormal cytology AOR = 5.1 (95% CI = 2.3-11.2), P < 0.001. CONCLUSIONS It was not possible to predict which HPV-infected women will have cytological abnormalities or notfrom anamnesis. In this study HPV 53 seemed more benign than other HPV genotypes. On the contrary, species n°9, containing 5 of the genotypes contained in the nonavalent HPV vaccine, was significantly associated with more cytological abnormalities. HPV testing and vaccination with the nonavalent vaccine should be implemented in these remote parts of French Guiana.

Abstract
Human papillomavirus (HPV) testing can identify women at risk of cervical cancer. Currently, molecular detection methods are the gold standard for identification of HPV. The three categories of molecular assays that are available are based on the detection of HPV DNA and include (1) non-amplified hybridization assays, such as Southern transfer hybridization (STH), dot blot hybridization (DB) and in situ hybridization (ISH); (2) signal amplified hybridization assays, such as hybrid capture assays (HC2); (3) target amplification assays, such as polymerase chain reaction (PCR) and in situ PCR. STH requires large amounts of DNA, is laborious and not reproducible, while ISH has only moderate sensitivity for HPV. The sensitivity of the HC2 assay is similar to that of PCR-based assays, with high sensitivity being achieved by signal rather than target amplification. PCR-based detection is both highly sensitive and specific. Since PCR can be performed on very small amounts of DNA, it is ideal for use on specimens with low DNA content. In the future, with the advance of technology, viral DNA extraction and amplification systems will become more rapid, more sensitive, and more automated.

Prevalence of Human Papillomavirus Infection and Cervical Cancer Screening among Riverside Women of the Brazilian Amazon. REVISTA BRASILEIRA DE GINECOLOGIA E OBSTETRÍCIA 2017; 39:350-357. [PMID: 28658700 PMCID: PMC10416179 DOI: 10.1055/s-0037-1604027] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Accepted: 04/19/2017] [Indexed: 10/19/2022] Open
Abstract
Purpose The aim of this study was to evaluate the overall and type-specific prevalence of human papillomavirus (HPV) infection among females living in riverside communities in the state of Pará, in the Eastern Brazilian Amazon. These communities are inhabited by low-income people, and are accessible only by small boats. Cervical cytology and risk factors for HPV infection were also assessed. Methods Cervical samples from 353 women of selected communities were collected both for Papanicolau (Pap) test and HPV detection. Conventional polymerase chain reaction (PCR) and real-time PCR were used to assess the overall and type-specific prevalence of HPV-16 and HPV-18, the main oncogenic types worldwide. Epidemiological questionnaires were used for the assessment of the risk factors for HPV infection. Results The mean age of the participants was 37 years (standard deviation [SD] ± 13.7). Most were married or with a fixed sexual partner (79%), and had a low educational level (80%) and family monthly income (< U$ 250; 53%). Overall, HPV prevalence was 16.4% (n = 58), with 8 cases of HPV-16 (2.3%) and 5 of HPV-18 (1.4%). Almost 70% of the women surveyed had never undergone the Pap test. Abnormal cytology results were found in 27.5% (n = 97) of the samples, with higher rates of HPV infection according to the severity of the lesions (p = 0.026). Conclusions The infections by HPV-16 and HPV-18 were not predominant in our study, despite the high prevalence of overall HPV infection. Nevertheless, the oncogenic potential of these types and the low coverage of the Pap test among women from riverside communities demonstrate a potential risk for the development of cervical lesions and their progression to cervical cancer, since the access to these communities is difficult and, in most cases, these women do not have access to primary care and public health services.

A cross-sectional study on HPV testing with type 16/18 genotyping for cervical cancer screening in 11,064 Chinese women. Cancer Med 2017; 6:1091-1101. [PMID: 28378404 PMCID: PMC5430103 DOI: 10.1002/cam4.1060] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2016] [Revised: 02/09/2017] [Accepted: 02/23/2017] [Indexed: 01/10/2023] Open
Abstract
Cytology‐based cervical cancer screening is restricted because of a lack of cytologists. Thus, HPV‐based instead of cytology‐based screening may be a more suitable strategy in China. Here, we assessed the effectiveness of HPV testing (Cobas® 4800 Test, Roche) and HPV‐based programs to detect high‐grade cervical intraepithelial neoplasia (CIN) or cancer compared with cytology (Thinprep, Hologic) and cytology‐based programs through a cross‐sectional study in 11,064 Chinese women aged 21–65 years who were enrolled from Longyou County in Zhejiang Province, China. The rates of HPV positivity and cytology abnormality were 9.8% and 6.1%, respectively. The HPV positivity rate had two age peaks, 21–24 (15.4%) and 60–65 (14.4%) years. According to adjusted data, HPV testing demonstrated significantly higher sensitivity and negative predictive value (NPV) than cytology for detecting CIN2 or worse (90.0% vs. 66.7%, 99.9% vs. 99.5%), and there was an acceptable specificity (91.3%) and positive predictive value (PPV, 12.5%). Furthermore, primary HPV testing with type 16/18 genotyping showed the highest sensitivity (78.6%) and NPV (99.7%) among four screening strategies, and there was similar specificity (96.8%) and PPV (23.9%) compared with co‐testing screening to detect CIN2+, while there were fewer colposcopies (4.2) and tests (106.3) performed than with co‐testing and primary cytology screening to detect a case of high‐grade CIN. The differences in effectiveness were approximately similar when CIN3+ was the identifying target. Our findings suggest that primary HPV testing with type 16/18 genotyping has a higher sensitivity and NPV, possesses optimal cost/effectiveness in the first round of screening and is a feasible strategy of cervical cancer screening for Chinese women.

Abstract
Background In French Guiana, cervical cancer is the second most frequent cancer in females. The objective of the present study was to describe the prevalence of HPV infections in women with normal cervical cytology living in the remote villages of French Guiana. Methods Before the study, the study team communicated in the remote villages on the importance of screening. All women from the target population were offered to participate. They signed informed consent during inclusion and then had a concomitant HPV-test and cervical smear. Only women with normal cytology and a good quality smear were analyzed. The detection of HPV-DNA was performed using the GREINER-BIO-ONE kit. Results Overall, 27.2% of women with normal cervical cytology had a positive HPV-test. There was a U-shaped evolution of prevalence with women over 50 years having the highest HPV prevalence, followed by the 20 to 29 years group. The most prevalent HPV genotypes were HPV 53(3.52%), 68(3.33%), 52(2.59%), 31(2.22%) and 16 (1.85%). The proportion of HPV 16 among HPV-infected women was 6.8%. Conclusions HPV prevalence in cytologically normal women was very high. The most prevalent genotypes were very different from what is usually described in the world, and notably in South America.

Abstract
Here, we evaluated the prevalence of Human Papillomavirus (HPV) in two groups of Chilean women. The first group consisted of 3235 women aged 18-64 years attended in six primary care centers of Santiago. The second group consisted of 456 women 18-85 aged who consulted the Gynaecology Department of the Reference Hospital of Santiago. Samples were collected from October 2012 to February 2016. Cervical swabs were analyzed both HPV genotyping by PCR and Reverse Line Blot, and cervical cytology by Pap testing. Results showed a prevalence of 12.0% HPV positive, 10.3% high-risk (HR) HPV types positive, 3.9% low-risk (LR) HPV types positive, and 1.0% Pap positive in group 1. The most frequent types were 16, 66, and 59, with a prevalence of 3.0%, 1.6%, and 1.5%, respectively. The prevalence were 71.9% HPV positive, 67.3% HR-HPV types positive, 13.6% LR-HPV types positive, and 62.5% Pap positive in group 2. The most frequent types were 16, 31, and 58, with prevalence of 33.6%, 10.5%, and 7.0%, respectively. Among infected women with HPV: 7.6% were infected with HPV16 or HPV18, 3.0% with HPV31, HPV33 or HPV45, and 6.7% with any other HR-HPV. These findings show great difference in HPV prevalence and types between primary care and reference center, and provide useful epidemiological information to assess the impact of HPV vaccination in the future.

Abstract
Cervical cancer is the second most frequent cancer in women in French Guiana. Studies have shown that populations living in the remote areas of the interior have early sexual debut and that multiple sexual partnerships are common. The objective of the present study was thus to determine the prevalence of human papillomavirus (HPV) infection in these areas. A study was conducted in women aged 20-65 years with previous sexual activity. Women were included on a voluntary basis after using local media and leaders to inform them of the visit of the team. HPV infection was defined by the detection of HPV DNA using the Greiner Bio-One kit. In addition to HPV testing cytology was performed. The overall age-standardized prevalence rate was 35%. There was a U-shaped evolution of HPV prevalence by age with women aged >50 years at highest risk for HPV, followed by the 20-29 years group. Twenty-seven percent of women with a positive HPV test had normal cytology. Given the high incidence of cervical cancer in French Guiana and the high prevalence of HPV infections the present results re-emphasize the need for screening for cervical cancer in these remote areas. Vaccination against HPV, preferably with a nonavalent vaccine, also seems an important prevention measure. However, in this region where a large portion of the population has no health insurance, this still represents a challenge.

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
The median age of cervical cancer (CC) presentation coincides with the mean age of menopause presentation (49 years) in Mexico. Here, we investigated the association between different HPV16 variants and early (≤ 49 years) or delayed (≥ 50 years) CC presentation. We conducted a case-case study that included 462 CCs, 386 squamous cell carcinomas (SCC), 63 adenocarcinomas (ACC), and 13 additional cell types. Variants were identified by PCR and DNA sequencing. The risk conferred by each variant for developing CC earlier than 50 years was analyzed using a univariate logistic regression model considering old-aged patients (≥ 50 years) and non-HPV16 cases as the reference variables. Overall, the frequency of HPV16 was 50.9%, and the only identified variants were the European A1/2 (31.2%) and the Asian-American D2 (10.8%), and D3 (8.9%). D2 was mainly associated with ≤ 49-year-old patients (15.9%); A1/2 was uniformly distributed between the two age groups (~31%), whereas D3 increased with age to a frequency of 11.8% in the older group. Only the D2 variant conferred a 3.3-fold increase in the risk of developing CC before 50 years of age (OR = 3.3, 95% CI = 1.7-6.6, p < 0.001) in relation with non-HPV16 cases. Remarkably, this risk was higher for ACC (OR = 6.0, 95% CI = 1.1-33, p < 0.05) than for SCC (OR = 2.8, 95% CI = 1.3-5.9, p < 0.01). Interestingly, when analyzing only the HPV16-positive CC, D2 increases (OR = 2.5, 95% CI = 1.2-5, p < 0.05) and D3 decreases (OR = 0.45, 95% CI 0.2-0.9, p < 0.05) the risk to develop CC before 50 years old in relation with A1/2 variant. These results indicated that D2 variant is associated with early and D3 with delayed CC presentation, whereas A1/2 variant was uniformly distributed between the two age groups.

Abstract
BACKGROUND Little is known about the epidemiological characteristics of papillomavirus (HPV) infection among North African countries. Herein, we conducted a molecular epidemiological study to investigate prevalence of HPV type and HPV-16 variants among cervical-screened unvaccinated Tunisian women. METHODS Cross-sectional study was performed on 494 Tunisian women visiting Women's Healthcare Centers. HPV-DNA detection was carried out on cervical samples using real-time polymerase chain reaction. HPV genotyping and HPV-16 variants were characterized by direct sequencing of L1 viral capsid gene. RESULTS The overall HPV prevalence was 34% (95% CI: 30-38%) with significantly higher prevalence among women with squamous intraepithelial lesions (SIL) than those with no intraepithelial lesions (NIL) 84% (95% CI: 76-92%) and 24.5% (95% CI: 20-29%) respectively. The distribution of HPV prevalence according to women's age shows a U-shaped curve and the highest HPV prevalence rates were observed among the youngest (≤25 years; 51.2%, 95% CI: 37-67%) and the oldest women (>55 years; 41.7%, 95% The HPV-16 prevalence was 32.8% (95% CI: 22-45%) among women with SIL and 9.2% (95% CI: 6-12%) among women with NIL. Whereas, the HPV-18 prevalence was 1.3% (95% CI: 0-5%) among women with SIL and 0.3% (95% CI: 0-1%) among women with NIL. Among HPV-16 positive women, European lineage (E) was identified as the predominant HPV-16 variant (85.7%, 95% CI: 76-95%). The frequency of E variant was lower among SIL than among NIL women (81%, 95% CI: 64-99%, and 88%, 95% CI: 77-100%, respectively). Conversely, the African-2 variant frequency was higher among SIL than among NIL women (18%, 95% CI: 1-36% and 6%, 95% CI: 2-14%, respectively). In multivariate analysis, young age was the only risk factor that is independently associated with HPV infection. Moreover, HPV infection and menopause were both found to be independently associated with SIL and HSIL. CONCLUSION HPV DNA testing should be proposed to young and menopausal Tunisian women. Considering HPV prevalence, only 13% of the Tunisian women could be protected by the bivalent HPV vaccine. These results may be helpful for designing an adapted HPV testing and vaccination program in Tunisia.

Abstract
OBJECTIVE To investigate clinical outcomes and 3-year persistence of human papillomavirus (HPV) infections among women in Mexico. METHODS A prospective study enrolled sexually active women attending primary healthcare clinics in metropolitan Monterrey, Mexico, between June 3 and August 30, 2002. Baseline data were collected and participants underwent HPV screening. Patients with HPV infections were asked to attend a repeat screening appointment after 3 years, when the same screening data were gathered. Descriptive analyses were performed and the prevalence of cervical lesions and viral infections were examined. RESULTS In total, 1188 patients who underwent initial HPV screening were included. Cervical lesions were detected in 5 (0.4%) patients and 239 (20.1%) patients had HPV infections; 129 (54.0%) of these patients attended 3-year follow-up. Among the 357 HPV serotypes identified, the most prevalent serotypes were HPV-59, HPV-52, HPV-16, and HPV-56, detected 62 (17.4%), 38 (10.6%), 27 (7.6%), and 18 (5.0%) times, respectively. Of the 129 patients attending 3-year follow-up, 104 (80.6%) were clear from HPV infections, 13 (10.1%) patients had persistent HPV infections, and 12 (9.3%) had HPV infections with different HPV types. CONCLUSIONS The HPV prevalence was 20.1% in the present study; the most prevalent infections were HPV-59, HPV-52, HPV-16, and HPV-56. At 3-year follow-up, 25 (19.4%) patients had HPV infections.

Abstract
Purpose Cervical cancer is a common cancer among women worldwide. An estimated 528,000 new cases and 266,000 deaths occurred in 2012. More than 85% of invasive cervical cancer cases occur in low- and middle-income countries. Cervical cancer ranks as the most common cancer among women in Ghana. We conducted a retrospective study to assess the descriptive epidemiology of cervical cancer in Ghana. We describe cervical cancer incidence and mortality rates for the regions served by two large hospitals in Ghana. Patients and Methods Information for women diagnosed with invasive cervical cancer between 2010 and 2013 was collected from the Komfo Anokye and Korle Bu Teaching Hospitals through review of medical, computer, and pathology records at the oncology units and the obstetrics and gynecology departments. Telephone interviews were also conducted with patients and relatives. Data were analyzed using summary statistics. Results A total of 1,725 women with cervical cancer were included in the study. Their ages ranged from 11 to 100 years (mean, 56.9 years). The histology of the primary tumor was the basis of diagnosis in 77.5% of women and a clinical diagnosis was made in 22.5% of women. For the 1,336 women for whom tumor grade was available, 34.3% were moderately differentiated tumors. Late stage at presentation was common. The incidence and mortality rates of cervical cancer increased with age up until the 75 to 79-year age group and began to decrease at older ages. The Greater Accra region had higher overall incidence and mortality rates than the Ashanti region. Conclusion Our study suggests that improvements in the application of preventive strategies could considerably reduce the burden of cervical cancer in Ghana and other low- and middle-income countries. The study provides important information to inform policy on cancer prevention and control in Ghana.

Abstract
BACKGROUND Cervical cancer remains an important cause of cancer mortality for Mexican women. HPV 16/18 typing may help to improve cervical cancer screening. Here we present the prevalence of high-risk human papillomavirus (hrHPV) including HPV16 and HPV18 from the FRIDA (Forwarding Research for Improved Detection and Access) population. METHODS Beginning in 2013, we recruited 30,829 women aged 30-64 in Tlaxcala, Mexico. Cervical samples were collected and tested for 14 hrHPV genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68). We used logistic regression to estimate odds ratios with 95 % confidence intervals for hrHPV infections according to putative risk factors. RESULTS Prevalence of infection with any of the 14 hrHPV types was 11.0 %. The age-specific prevalence of all hrHPV formed a U-shaped curve with a higher prevalence for women aged 30-39 and 50-64 than women aged 40-49. Across all age groups, 2.0 % of women were positive for HPV16 and/or HPV18 (HPV16/18), respectively. HPV16/18 prevalence also showed a U-shaped curve with increased prevalence estimates for women aged both 30-39 and 60-64. Both prevalence curves had a significant quadratic age coefficient. Infections with hrHPV were positively associated with an increased number of lifetime sexual partners, a history of sexually transmitted disease, being unmarried, use of hormonal contraception, having a history of smoking and reported condom use in the multivariate model. CONCLUSIONS The FRIDA population has a bimodal distribution of both hrHPV and HPV16/18 positivity with higher prevalences at ages 30-39 and 60-64. These findings will help to evaluate triage algorithms based on HPV genotyping. TRIAL REGISTRATION The trial is registered with ClinicalTrials.gov, number NCT02510027 .

Abstract
Cervical cancer is the fourth most common malignancy in women worldwide. In Chile, cervical cancer is the second leading cause of death among women of reproductive age, causing more than 600 deaths annually. This study was carried out to determine the burden and confirm the predominant human papillomavirus (HPV) genotypes among women presenting for cervical cancer screening in public health services in Chile. Women aged 18-64 years residing in the north and central areas covered by six primary care centers of Santiago, Chile, were invited to participate from March 2014 to August 2015. Cervical swabs were examined both HPV genotyping by PCR and Reverse Line Blot, and cervical cytology by Pap testing. A total of 1738 women were included in this study: 11.1 % were HPV positive, 9.7 % were high-risk types positive, 3.2 % were low-risk types positive, 1.4 % were Pap positive and 0.9 % were positive by both tests. The four most predominant genotypes were 16, 66, 51 and 59, with prevalence of 2.8, 1.4, 1.2 and 1.2 %, respectively. Multiple HPV infections were detected among 3.8 % participants. Age-specific prevalence of HPV showed a peak in HPV infection at younger ages (≤30 years), declining to a plateau in middle age. Among women with normal cytology, the 9.4 % were HPV positive, while 58.3 % of women with abnormal cytology were HPV positive. These findings show new epidemiological data confirming HPV 16 and 66 as the most predominant genotypes in Chile. These data are important for design successful strategies for prevention of cervical cancer in Chile.

Abstract
Background The association of human papillomavirus (HPV) types to neoplastic lesions increase as a function of their oncogenicity and the duration of the infection since lesion severity progresses from low-grade to high-grade and cancer. In an outbreak, the prevalence of the HPV type involved would increase and the proportion of the associated low-grade lesions would predominate over severe lesions. In this study, the prevalence of HPV types and their association to neoplastic lesions was determined in women subjected to colposcopy in San Luis Potosí, Mexico. Methods DNA from high-risk (HR) and low-risk (LR) HPV types was identified by E6 nested multiplex PCR in cervical scrapes from 700 women with normal cytology, atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL) or invasive cervical cancer (CC). Results Overall HPV-DNA prevalence was 67.7 %, that of HR-HPV was 63.1 %, and that of LR-HPV was 21.3 %. The highest prevalence (78.2 %) occurred in the 15–24 year group, whereas that of single infections was 52 % and that of multiple infections (i.e., by 2–6 HPV types) was 48 %. The most prevalent HR types were HPV33 (33.1 %), HPV16 (16.6 %), HPV18 and HPV51 (6.7 % each). HR-HPV prevalence was 29.6 % in normal cytology, 26.7 % in ASCUS, 63.3 % in LSIL, 68.2 % in HSIL, and 90.5 % in CC. Three prevalence trends for HR-HPV types were found in neoplastic lesions of increasing severity: increasing (LSIL < HSIL < CC) for HPV16, HPV39, HPV18, HPV58, HPV31 and HPV35; asymptotic (LSIL < HSIL ≈ CC) for HPV51 and HPV68; U-shaped (LSIL < HSIL > CC) for HPV33. Conclusions Two-thirds of the women subjected to colposcopy from 2007 to 2010 in San Luis Potosí have HPV infections which predominate in the 15–24 years group. Around half of the infections are by one viral type and the rest by 2–6 types. HPV33 is the most prevalent type, followed by HPV16. Overall HR-HPV prevalence increases with the severity of neoplastic lesions. HPV33 prevalence is highest in LSIL and its U-shaped trend with progressing neoplastic lesions differs from the growing/asymptotic trends of other HR-HPV types. An ongoing or recent HPV33 outbreak is consistent with its high prevalence and anomalous association to LSIL.

Abstract
OBJECTIVE Distribution of age of onset of recurrent respiratory papillomatosis (RRP) is generally described to be bimodal, with peaks at approximately 5 years and 30 years. This assumption has never been scientifically confirmed, and authors tend to refer to an article that does not describe distribution. Knowledge of the distribution of age of onset is important for virological and epidemiological comprehension. The objective of this study was to determine the distribution of age of onset of RRP in a large international sample. DESIGN Cross-sectional distribution analysis. PARTICIPANTS Laryngologists from 12 European hospitals provided information on date of birth and date of onset of all their RRP patients treated between 1998 and 2012. Centers that exclusively treated either patients with juvenile onset RRP or patients with adult onset RRP, or were less accessible for one of these groups, were excluded to prevent skewness. MAIN OUTCOME MEASURES A mixture model was implemented to describe distribution of age of onset. The best fitting model was selected using the Bayesian information criterion. RESULTS Six hundred and thirty-nine patients were included in the analysis. Age of onset was described by a three component mixture distribution with lognormally distributed components. Recurrent respiratory papillomatosis starts at three median ages 7, 35 and 64 years. CONCLUSIONS Distribution of age of onset of RRP shows three peaks. In addition to the already adopted idea of age peaks at paediatric and adult age, there is an additional peak around the age of 64.

[PMID: 27547836 PMCID: PMC4986989 DOI: 10.1016/j.pvr.2015.09.001] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/19/2015] [Revised: 08/31/2015] [Accepted: 09/05/2015] [Indexed: 11/30/2022]
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 To study the incidence, persistence, and determinants of human papillomavirus (HPV) infection in a population of Inuit women from Nunavik, Quebec, by overall HPV infection, Alphapapillomavirus (α) species, and oncogenic risk grouping. METHODS We recruited a cohort of Inuit women living in communities in Nunavik when they presented for routine care. Baseline sociodemographic and lifestyle characteristics were collected and cervical specimens collected throughout the follow-up period were tested for HPV-DNA using the PGMY Line-blot assay. RESULTS A total of 416 women were eligible for this analysis. Almost 40% of women acquired a new any-type HPV infection, at a rate of 14.44 infections per 1000 women-months. High-risk HPV infections were acquired at a higher rate than low-risk infections and persisted for longer durations. Multivariate logistic regression found age and marital status to be the most important predictors of overall HPV infection acquisition. Over the study period, 36.1% of women cleared their incident infections. The cumulative incidence of any HPV type at 12 months was 10.3% (95% confidence interval, 7.9-13.1). No predictors of clearance were found. CONCLUSIONS The high incidence and persistence of HPV infections found demonstrate that this population is at high risk for HPV infection. These data provide a deeper understanding of the HPV infection experience of Inuit women, but they may also help evaluate vaccination strategies currently used for this high-risk population.

Abstract
BACKGROUND HPV is one of the most common sexually transmitted infections. However, little is known about its prevalence in the female population in Rasht, Northern of Iran. The aim of this study was to find the incidences of HPV viruses in high-risk women in Rasht by wet Pap smear from 2010 to 2015. MATERIALS AND METHODS This cross-sectional study investigated HPV prevalence and its genotype distribution among 103 apparently healthy and non- healthy women with abnormal cells in pap exam. DNA samples were extracted by boiling and phenol - chloroform methods, then used as template for amplifying of specific fragment of HPV genome by PCR using GP5+ / GP6+ primers. PCR products were electrophoresed in 1.5% agarose gel (Roche, Germany) containing Sybrsafe. DNA ladder (Roche Co, Germany) was used to detect the molecular weights of observed bands under UV lamp. RESULTS Overall, 4/98 women (4.08%) with normal cells and 1/5 women (20%) with abnormal cells were positive for at least one of the high risk HPV types in wet Pap smear. The most HPV infection was found in 26 to 39-year-old individuals. CONCLUSION We evidenced a moderate prevalence of HPV infection but needs to be given more attention because in apparently healthy women also, HPV infection was observed. Health officials should conduct the study and wider screening of this infection occurring in this province. Screening for this infection must be recommended in this region.

Abstract
High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papillomavirus infections of the oral mucosa without pathology. A cross-sectional study was performed; samples from 390 women seeking prenatal care, Pap smears, family planning or gynecological diseases were studied. Oral cells were collected by direct swab sampling. Information regarding sociodemographic status, sexual behavior, infectious diseases, contraceptive history and tobacco and alcohol consumption were obtained through direct interviews. HPV and genotypes were detected by type-specific polymerase chain reaction. Our results revealed that 14% of the women studied had an oral HPV infection. Women ≤ 20 years of age had the highest HPV prevalence (24.5%). In total, seven genotypes were identified, including the high-risk genotypes 16, 18, 58 and 59 and the low-risk genotypes 6, 81 and 13, the latter of which is a type exclusive to oral mucosa. Sexual behavior was not associated with the presence of genital HPV types in the oral mucosa. Genital HPV types were present in the oral mucosa of women without associated clinical manifestations; however, sexual behavior was not associated with infection, and therefore others routes of transmission should be explored.

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.

Prevalence and risk factors for High-Risk Human Papillomavirus (hrHPV) infection among HIV-infected and Uninfected Rwandan women: implications for hrHPV-based screening in Rwanda. Infect Agent Cancer 2014; 9:40.

Abstract
BACKGROUND New World Health Organization guidelines recommend high-risk human papillomavirus (hrHPV) screen-and-treat strategies for cervical cancer prevention. We describe risk of, and risk factors for, testing hrHPV positive in a pilot study of hrHPV screen-and-treat conducted in Rwanda. METHODS A total of 2,964 women, 1,289 HIV-infected (HIV [+]) and 1,675 HIV-uninfected (HIV [-]), aged 30-60 years and living in Rwanda were enrolled in 2010. Cervical specimens were collected and tested by careHPV, a DNA test for a pool of 14 hrHPV types. Prevalence with binomial 95% confidence intervals (95% CI) and determinants of testing hrHPV positive were calculated. RESULTS hrHPV prevalence was higher in HIV [+] (31.8%, 95% CI = 29.2-34.4%) than HIV [-] women (8.2%, 95% CI = 6.7-9.8%; P < 0.0001). Among HIV [+] women, there was a significant trend (ptrend <0.001) of higher hrHPV prevalence with lower CD4 cell count, with the highest hrHPV prevalence among those with <200 CD4 cell counts (45.5%, 95% CI = 34.8-56.4%). In multivariate analysis of HIV [+] women, testing hrHPV positive was positively associated CD4 count of <200 cells/μL, history of 3 or more sexual partners, and history of using hormonal contraception, and negatively associated with older age. In HIV [-] women, testing hrHPV positive was negatively associated only with older age groups of 45-49 and 50-60 years and surprisingly was not associated with lifetime number of sexual partners. CONCLUSION hrHPV prevalence is high in HIV [+], especially in women with the lowest CD4 cell counts, which may have implications for utilizing hrHPV-based screening strategies such as screen-and-treat in these high-risk subgroups.
