Background: Human Papillomavirus (HPV) is a DNA virus with more than 100 genotypes, at least 12 of which are high-risk and associated with high-grade cervical lesions. Data on the prevalence of high-risk HPV genotypes among women are not yet available for the total regions of Iran. Objectives: The present study aimed to determine the prevalence of high-risk HPV types among women screened for cervical carcinoma in Yazd and compare the cytology, histology, and colposcopy results. Methods: In this cross-sectional study, 402 women referring to gynecology clinics of Shahid Sadoughi University of Medical Sciences, Yazd, Iran, were selected. The Pap smear and HPV typing were performed on cervical samples. The high-risk HPV types were detected by the polymerase chain reaction (PCR)-based reverse blot hybridization assay. Colposcopy was carried out on patients with high-risk HPV types, and biopsies were taken for histological examination. Results: Among 402 women screened by HPV-PCR, 32 (7.97%) women were positive for high-risk HPV types. Human papillomavirus 16 and HPV18 were the most frequent genotypes (46.9%). The cytology, histology, and colposcopy results were abnormal in 56.2%, 29.1%, and 71.9% of patients, respectively. Pap smear had 100% sensitivity and 58.3% specificity for the detection of high-grade cervical lesions, while these values for colposcopy were 75% and 87.5%, respectively. Conclusions: The frequency of high-risk HPV types was relatively low among women living in Yazd than in those from other provinces of Iran. A significant percentage of patients with HPV had normal cervical cytology and histology. Therefore, HPV typing is recommended to decrease the development of cervical cancer. Colposcopy had acceptable sensitivity and specificity for the detection of high-grade cervical lesions.

In developing countries, cervical cancer is the most common cause of cancer related to mortality in women. But the epidemiology of human papillomavirus (HPV) in different areas of Bangladesh is largely unknown both in risk groups and in the general population. The objective of the present study was to determine the risk factors associated with having HPV and the prevalence of high-risk HPV types among women with highrisk behaviour and to assess its potential impact on preventive strategies as the sex workers are at increased risk for sexually transmitted infections (STI), HPV and hence cervical cancer. Cervical swab from 293 sex workers in Dhaka City between August and September 2003 and between February 2005 and May 2006 were screened for HPV DNA using an HPV short fragment (E6) polymerase chain reaction (PCR) based assay. HPV positive samples were genotyped with nested multiplex polymerase chain reaction (NMPCR) for the highrisk types. The overall HPV prevalence in sex workers was 75.8%, whereas for the high risk type it was 49.8%. Prevalence of single genotype and multiple types of HPV was 33.1 and 16.7% respectively. The most prevalent high-risk HPV types, in order of prevalence rate, were HPV16, HPV18, HPV58, HPV45, HPV31 and HPV33. Both HPV 16 and HPV 18 were present in 21% of the cases. Targeting HPV 16 and 18 with prophylactic vaccines could possibly have an important impact on the incidence of invasive cervical carcinoma in this group of women. Primary prevention and cervical cancer screening programmes should be optimized more and run yearly among the general population. It is proposed to screen sex workers when they enter prostitution regardless of their age.

Abstract Background Persistent infection by high-risk Human Papillomavirus (hrHPV) are the major cause of cervical cancer. Studies report disparities in the incidence of infection and the various genotypes of this virus in different age groups, suggesting a higher frequency of hrHPV in young women and low-risk subtypes being predominant in older women. This study aimed to investigate the incidence and distribution of hrHPV genotypes in postmenopausal women as well as the correlation with the cytological findings. Methods 16 859 women, aged 50–64 years, performed cervical cancer screening test in Friuri Venezia Giulia region, Italy. The infection was evaluated by the Polymerase Chain Reaction methodology and the positive samples were evaluated by Liquid Based Cytology according to the Bethesda System from 2014. A statistical analysis was performed to study the molecular and cytological data of this population. Results hrHPV infection were found in 5.8% of the women and 78.3% of these were caused by hrHPV other than HPV16 and HPV18 (). Also, 65.7% of the positive samples were negative for intraepithelial lesion or malignancy while low grade squamous intraepithelial lesion was the most frequent (22.4%). There was an increase in the number of high-grade intraepithelial lesions in the presence of HPV16 compared to that recorded when this genotype was absent (20.8% vs. 8.5%). No cervical cancers were detected. Conclusions Infection with hrHPV is uncommon in postmenopausal women and it is mostly caused by subtypes less associated with the development of cervical cancer. Yet, HPV16 infection triggers the development of high-grade lesions.

The Impact

Human papillomavirus (HPV) has been identified as the main etiological factor in the developing of cervical cancer (CC). This finding has propitiated the development of vaccines that help to prevent the HPVs 16 and 18 infection. Both genotypes are associated with 70% of CC worldwide. In the present study, we aimed to determine the emergence of high-risk nonvaccine HPV after actual vaccination scheme to estimate the impact of the current HPV vaccines. A SIR-type model was used to study the HPV dynamics after vaccination. According to the results, our model indicates that the application of the vaccine reduces infection by target or vaccine genotypes as expected. However, numerical simulations of the model suggest the presence of the phenomenon called vaccine—induced pathogen strain replacement. Here, we report the following replacement mechanism: if the effectiveness of cross-protective immunity is not larger than the effectiveness of the vaccine, then the high-risk nonvaccine genotypes emerge. In this scenario, further studies of infection dispersion by HPV are necessary to ascertain the real impact of the current vaccines, primarily because of the different high-risk HPV types that are found in CC.

AbstractObjectiveHigh-risk HPV (human papillomavirus) is found to be responsible for 4.5% of all cancer, especially cervical cancer. The prevalence of high-risk HPV associated with cervical lesions is not well- known in Saudi Arabia. This study aims to highlight the genotypes of high-risk HPV associated with pre- malignant cervical lesions.MethodsOver 6 years (2013 - 2018), 5091 Pap (Papanicolaou) smears results and 170 high-risk HPV test results were collected from the Information System at King Fahd University Hospital. Statistical analysis was performed using the software SPSS (Statistical Package for Social Sciences).ResultsOut of 5091 Pap smears, only 1.89% (n=96) were abnormal; 0.18% (n=9) were malignant (7 Squamous cell carcinomas and 2 adenocarcinomas), while 1.7% (n=87) showed pre-cancerous lesions, 44 ASCUS (Atypical Squamous Cells of Undetermined Significance), 17 LSIL (Low-grade Squamous Intraepithelial Lesions), 12 HSIL (High-grade Squamous Intraepithelial Lesions), and 14 AGC (Atypical Glandular Cells). Out of 170 patients co-tested for high-risk HPV, only 13.5% (n=23/170) had positive results (5 cases were positive for HPV16, 1 case was positive for both HPV16 and 18, while the remaining 17 cases were positive for high-risk HPV other than 16 or 18), among them, 6.47% (n=11/170) had normal Pap smear, while 7.06% (n=12/170) patients had abnormal Pap smear; 4 ASCUS, 6 LSIL and 2 HSIL. Statistical analysis showed a significant correlation between HPV findings and the Pap smear results (P- value 0.000), however, no significant correlation was found with the patients’ age and/or nationality.DiscussionOur study showed a unique distribution of high-risk HPV genotypes which reflects different geographical infection patterns. Furthermore, the high association of high-risk HPV with normal Pap smears highlights the need, for all women at risk, to be co-investigated for high-risk HPV. These findings could help in customizing regional vaccine-combinations and screening programs.

Low Prevalence

Human papillomavirus (HPV) infection is a significant etiological factor and an important prognosticator in cervical cancer. Indeed, researchers worldwide have confirmed these roles for high-risk HVPs in over 70% of cervical cancer cases. According to the World Health Organization, approximately 561,200 new cancer cases (5.2% of all new cancers) are attributed to HPV infection. Over 120 types of HPV are classified further as either low-risk HPV (LR-HPV) or high-risk HPV (HR-HPV) based on their oncological potential of transforming cells. The LR-HPV types cause benign hyperproliferative lesions (i.e. genital warts) while the HR-HPV types are strongly associated with premalignant and malignant cervical lesions. Data on the prevalence of HPV, survival of infected patients, and mortality rate are scarce in Saudi Arabia. The unsubstantiated assumption of a low prevalence of HPV in Saudi Arabia has contributed to limiting HPV research in this conservative country. Therefore, the goal of this review is to shed light on the current HPV research being conducted and the prevalence of HPV in Saudi Arabia.

Human papillomavirus (HPV) is the primary infectious agent for the development of cervical cancer, although the presence of the virus alone is insufficient for viral development and proliferation; this can be attributed to the increase in potential oncogenic risk, along with other risk factors. In the present investigation, the prevalence of high-risk HPV was determined from samples of premalignant or malignant cervical cytology in women from the southern region of Ecuador. The kit we used was able to detect genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59. In addition, 64.5% of the analyzed samples were positive for HPV, with genotypes 16 and 18 being the most prevalent (16 was detected in 148 samples and 18 in 108). Genotypes 58 and 51 were the third most frequent simple and multiple infections, respectively. The data are very similar to those obtained worldwide, suggesting that the strategy of sex education, and the use of vaccines as primary prevention agents, could significantly decrease the incidence and mortality rate of cervical cancer in the southern region of Ecuador.

High-risk human papillomavirus (HPV) infection and viral persistence is a major risk factor in the development of squamous intraepithelial lesions and invasive carcinoma of the cervix. In the United States, deaths due to squamous cell carcinoma of the cervix have fallen by 75% since the 1960s because of Papanicolaou (Pap) smear screening. However, the traditional Pap had a sensitivity of about 70% for detecting clinically significant precancerous lesions and cancer because of sampling and interpretive errors. The introduction of 2 liquid-based Pap smear collection systems in the 1990s, the use of HPV testing as a triage and co-testing with Pap smear, and the introduction of 2 automated screening devices have had a significant impact on improving the detection of such precancerous lesions. This review provides an analysis of the changes in Pap smear collection, improvements in screening, the evolutionary changes of high-risk HPV testing, reporting terminology of Pap smears, and clinical management guidelines. The future impact of 2 prophylactic HPV vaccines on the incidence of cervical carcinoma is also discussed. This article also discusses alternatives such as primary screening for high-risk HPV testing with visual inspection for cervical cancer detection used in resource-poor settings with a high incidence of cervical cancer.

Abstract Background The Pap smear is a screening examination that detects abnormal cervical cells and may be paired with human papillomavirus (HPV) testing in order to detect high-risk, oncogenic HPV strains. The incidence of cervical cancer varies among groups due to racial and ethnic disparities, and 80% of cases occur in developing countries. Mortality rates for cervical cancer in the Middle East are disproportionately higher when compared to developed countries. Our study aims to assess the prevalence of HPV and cervical cancer among a subset of Arab-American women in southeast Michigan. Methods The study is a retrospective chart review of women who presented for routine cancer screening as part of the Breast and Cervical Cancer Control Program (BCCCP), at the Arab-American Center for Economic and Social Services Clinic in southeast Michigan between 2003-2019. Paper charts were reviewed for information such as age, date of birth, monthly income, tobacco use, cervix-related gynecological examination performance, cervical cytology results, and HPV testing results. Women between the ages of 21 and 65 were included. In instances where cytology was performed, results and details of high-risk HPV testing were documented. In instances where high-risk HPV testing was performed, negative results were documented as such, and positive results were documented as either positive for HPV 16, 18, or other high-risk strains, or unknown if serotype testing was not available. Results A total of 464 charts from the BCCCP program were reviewed. All women included were uninsured and had immigrated from Middle Eastern countries, including Yemen and Lebanon. The average age of the women was 48.3 years. Of 464 women, 6% (n=28) of women declined to have a Pap smear. 85 women reported they had never had a Pap smear. Of the 436 women who did undergo Pap smear, 42 women (9.6%) had an abnormal pap smear. The remaining results are summarized in Table 1. Table 1 Conclusion Our study results show a trend toward HPV serotype 16 and other serotypes compared to HPV serotype 18 in Arab-American women who recently immigrated to the United States. However, this needs to be studied on a larger cohort of patients to determine if these serotypes are more common among this ethnicity compared to the general population.

High Risk Hpv

Human papillomaviruses (HPVs) are the etiological agents of several genital cancers, including cancer of the uterine cervix. The detection of HPV infection in genital samples may increase the sensitivity of primary and secondary screenings of cervical cancer. HPV testing may also improve the specificity of screening programs, resulting in the avoidance of overtreatment and cost savings for confirmatory procedures. The major determinants of clinical progression of HPV infection include persistence of HPV infection, involvement of high-risk HPV types, high HPV viral load, integration of viral DNA and presence of several potential cofactors. Signal amplification HPV-DNA detection techniques (Hybrid Capture II, Digene Corporation, USA) are standardized, commercially available, and capable of detecting several high-risk HPV types. They also increase the sensitivity of screening for high-grade lesions in combination with cytology. The sensitivity of these techniques to detect high-grade lesions is higher than that of cytology, but the referral rate for colposcopy is greater. These techniques are approved for the triage to colposcopy of women with cervical smears interpreted as atypical squamous cells of undetermined significance. Triage and screening for cervical cancer using HPV will probably be restricted to women aged 30 years or older because of the high prevalence of infection in younger women. Amplification techniques are ideal for epidemiological studies because they minimize the misclassification of HPV infection status. These techniques can detect low HPV burden infections. Consensus primers amplify most genital types in one reaction, and the reverse hybridization of amplicons with type-specific probes allows for the typing of HPV-positive samples. Consensus PCR assays are currently under evaluation for diagnostic purposes. HPV testing is currently implemented for the clinical management of women.
