BACKGROUND Cervical cancer is among the most common type of cancers in women and is associated with human papillomavirus (HPV) infection. OBJECTIVE The link between cervical cancer and high-risk HPV infection has been well documented, although the effect of simultaneous infection with high- and low-risk HPV or low-risk HPV alone on the risk of developing cervical malignancy is remained to be unanswered in guideline METHODS We have investigated the association of high and low-risk HPVs (HR or LR) genotype with cervical carcinoma risk, as well as pathological and cytological information in cases recruited from a population-based cohort study of 790 patients. RESULTS The percentage of HR+LR and HR-HPV16/18 were 9.30% and 11.20% in class II, 7.15% and 7.10% in class IV and 7.15% and 5.80% in As-CUS smears. Interestingly concurrent infection with HR-HPV and LR-HPV types led to a notable decline in the risk of developing malignancy in comparison with the high-risk group (OR=0.3 (0.098-0.925), p-value=0.04). The percentage of individuals with cervical malignancy was 10.2% and 28.2% within the co-infected and the HR-HPV participants. CONCLUSIONS Our finding demonstrated that simultaneous infection with high- and low-risk HPV reduces the risk of cervical malignancy.

Abstract 64 Background: The incidence, prevalence, persistence, and multiplicity of high-risk HPV infection is different between HIV positive and HIV negative women. We examined the association between HIV, prevalent HPV, and persistent HPV infections among women in a prospective cohort in Nigeria. Methods: We enrolled women presenting at cervical cancer screening programs in Abuja, Nigeria, between 2012 and 2014 and collected information on their demographic characteristics, risk factors of HPV infection, and cervical exfoliated cells samples at baseline, 6 month and 12 month follow-up visits. DNA enzyme immunoassay (DEIA) and Roche Linear Array HPV Genotyping Test were used to characterize HPV. Persistent HPV infection was defined as a positive result on 2 consecutive DEIA tests. We used logistic regression models to estimate the association between HIV and risk of HPV infection. Results: Among the 1,020 women enrolled, the mean age (±SD) was 37(8), and 44% and 56% were HIV+ and HIV-, respectively. HPV52 and 35 were the most common HPV types in the study population. The prevalence was 34% for any HPV, 24% for persistent HPV and 9% for multiple HPV infections; these were higher among HIV+ women (p-value <0.001). The multivariate odds ratio (OR) and 95 % CI comparing HIV+ to HIV- women was 6.29 (95% CI 3.64 – 10.87, p-value <0.001) for any high-risk HPV; 6.22 (95% CI 3.02 – 12.83, p-value <0.001) for persistent high-risk HPV; and 6.46 (95% CI 2.69 – 15.52, p-value <0.001) for multiple high-risk HPV infections, Conclusions: HIV infection is associated with increased risk of persistence and multiplicity of low-risk and high-risk HPV infections. These findings may explain, in part, the increased risk of cervical cancer among women with HIV infections. AUTHORS' DISCLOSURES OF POTENTIAL CONFLICTS OF INTEREST: Sally N.

Abstract Background The incidence rate of cervical cancer is increasing yearly. The persistent infection of high-risk human papillomavirus (HPV) is the main factor leading to cervical cancer. HPV infection is double peak type. This study aimed at analyzing the HPV distribution characteristics, infection rate, and risk of age in pre- and postmenopausal women. So as to provide reference for the prevention of HPV infection and cervical cancer screening strategy. Methods A retrospective analysis of 4614 women who underwent cervical cytology, and HPV examination from January 2018 to October 2019 at the healthcare department of Wuhan Union Hospital was done. We explored the characteristics and distribution of HPV infections around the menopause, then comparing the infection rate of HPV in postmenopause and over 65 years old, in order to analyze the influence of different ages on HPV infection. Results Generally, the HPV infection rate was 13.10% (539/4115), whereby the high-risk subtype constituted 73.84% (398/539) of all positive cases. On the other hand, the HPV39 infection was more common in postmenopausal women; however, there was no significant difference in the distribution of the other types in the pre- and postmenopausal women. The first four types were 52/53/58/16. The results further showed that the rates of HPV infection before and after menopause were 12.34% (367/2975) and 15.09% (172/1140), respectively, which had no significant difference (P = 0.056), but more susceptible to high-risk HPV infection after the age of 65 (P = 0.041). Except for 40 years old to menopause, the infection rate of high-risk HPV in this age group was different from that in postmenopause (P = 0.023, 0.729 (0.555, 0.957)), other age groups had no significant effect on high-risk HPV infection. Conclusions It was concluded that whether menopause has nothing to do with HPV infection. Moreover, the risk of high-risk HPV infection in women aged 40 to premenopausal is relatively low, but the infection rate increases after 65. Hence the cutoff screening age should be appropriately prolonged.

Abstract Background Human papillomavirus (HPV) causes oral warts and oropharyngeal cancer (OPC). Human papillomavirus-attributable OPC incidence among men is significantly increasing worldwide, yet few studies have reported oral HPV across multiple countries or examined factors associated with low- and high-risk HPV separately. Methods Oral gargles from 3095 men in the multinational HPV Infection in Men (HIM) Study were HPV genotyped. Multivariable models assessed factors independently associated with high-risk and low-risk HPV prevalence. Results The prevalence of high-risk and low-risk HPV was 6.0% and 2.8%, respectively. Greater number of sexual partners was only associated with high-risk HPV (1.88; 95% confidence interval [CI], 1.22–2.90) prevalence. In multivariable models, residing in Mexico (1.66; 95% CI, 1.15–2.40) and smoking (1.66; 95% CI, 1.13–2.44) were significantly associated with high-risk HPV, and history of consistent gum bleeding (2.16; 95% CI, 1.35–3.45) was significantly associated with low-risk HPV. Gender of the sexual partner did not alter the results for either high- or low-risk HPV endpoints. Conclusions Different factors were independently associated with high- and low-risk oral HPV. Oral sexual behaviors were associated with high-risk HPV, and oral health was associated with low-risk HPV. High-risk HPV prevalence differed by country of residence, highlighting the need for additional studies in multiple countries.

1576 Background: The incidence of cervical cancer has remained stable in HIV+ women but the prevalence and multiplicity of high risk HPV (hrHPV) infection, a necessary cause of cervical cancer, appears different comparing HIV+ to HIV- women. Because this has not been well studied in Africa, we conducted this study to identify single and multiple hrHPV infection among HIV+ and HIV- women in Nigeria. Methods: We enrolled HIV+ and HIV- women presenting at our cervical cancer screening program in Abuja, Nigeria between April 2012 and August 2012. Using a nurse administered questionnaire, we collected information on demographic characteristics, risk factors of HPV infection and cervical exfoliated cells samples from all participants. We used Roche Linear Array HPV Genotyping Test to characterize the prevalent HPV according to manufacturer’s instruction and logistic regression models to estimate the association between HIV infection and the risk of high-risk HPV infection. Results: There were 278 participants, 40% (111) of whom were HIV negative, 54% (151) HIV positive and 6% (16) with HIV status unknown. Of these, 108 HIV+ women cases and 149 HIV- women controls were available for analysis. The mean ages (±SD) were 37.6 (±7.7) for HIV+ and 36.6 (±7.9) years for HIV- women (p-value = 0.34). Cases and controls had similar socio-demographic characteristics. Among HIV+ women, HPV35 (8.7%) and HPV56 (7.4%) were the most prevalent hrHPV, while HPV52 and HPV68 (2.8%, each) were the most prevalent among HIV- women. The age adjusted RR for prevalent hrHPV was 4.18 (95% CI 2.05 – 8.49, p-value <0.0001), comparing HIV+ to HIV- women. The multivariate RR for any HPV and multiple hrHPV was 3.75 (95% CI 2.08 – 6.73, p-value 0.01) and 6.6 (95% CI 1.49 – 29.64, p-value 0.01) respectively, comparing HIV+ to HIV- women, adjusted for age, and educational level. Conclusions: HIV infection was associated with increased risk of any HPV, hrHPV and multiple HPV infections. Oncogenic HPV types 35, 52, 56 and 68 may be more important risk factors for cervical pre-cancer and cancer among women in Africa. Polyvalent hrHPV vaccines meant for African populations should protect against HPV types other than 16 and 18.

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.

The purpose of the study was to assess detection rates of human papillomavirus in cervical cancer cases of Nizhny Novgorod. Materials and methods. We used the real-time polymerase chain reaction (PCR) to test samples of mucosa lining of the cervical canal and/or transformation zone taken from 630 women with cervical dysplasia of different degrees and 107 incident cases of cervical cancer that did not undergo treatment. The detection and differentiation of 14 genotypes of high-risk human papillomaviruses (HPV) was carried out using the AmpliSens® HPV HCR-genotype-FRT PRC kit. Results. The overall infection rate of women with oncogenic human papillomaviruses was 41.8%. Among the genotypes, HPV 16 (39.2%), 18 (15.5%), 33 (16.6%), and 56 (11.9%) predominated. A high prevalence of oncogenic HPV was detected in the women with cervical intraepithelial neoplasia (58.1%) and cervical cancer (90%). The spectrum of genotypes in women with neoplasia of various degrees differed. In women with CIN II and CIN III, vaccine-preventable HPV genotypes (HPV 16 and 18) playing the leading role in the development of cervical cancer were the most frequent. The same genotypes dominated in the women with invasive cervical cancer. One oncogenic HPV genotype was usually found in the infected women (69%). The high-risk HPV infection was often combined with Ureaplasma ssp (49.3%), Mycoplasma hominis (20.1%), Cytomegalovirus (21.1%), and Herpes simplex I/II (18.2%) infections. Combinations of high-risk HPV with Chlamydia trachomatis and Herpes 6 were found in 8.3% and 5% of the cases, respectively. Conclusions. Our findings proved a wide prevalence of high carcinogenic risk HPV 16 and 18 genotypes, thus indicating the expediency of using Cervarix and Gardasil vaccines registered in the Russian Federation and containing antigens to these types of virus for specific prevention of the HPV infection.

Abstract Background: Human papillomavirus (HPV) is the most common sexually transmitted disease in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women.Methods: From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in Belém. The detection of HPV infection was performed by nested PCR and HPV type was performed using the commercial kit.Results: The prevalence of HPV infection was 63,3%. Of the 47 genotyped samples, 40,4% was found positive for high risk-HPV 16 and 12.8% for high risk-HPV 52. HPV infection was predominant in the group of women with no incidence of cytological abnormalities and more prevalent in women of reproductive age, unmarried, low education level and who used condoms during sexual intercourse. It was observed an association between HPV infection and independent variables, such as condom use, multiple sexual partners and history of sexually transmitted diseases.Conclusions: High-risk types of HPV infection were prevalent in our study. Infection with multiple high-risk HPV genotypes may potentiate the development of cervical cancer in HIV-infected women.

Infection with human papillomavirus (HPV) is the main cause of cervical cancer, the principal cancer in women in most developing countries. Molecular epidemiologic evidence clearly indicates that certain types of HPV are the principal cause of invasive cervical cancer and cervical intraepithelial neoplasia. Comprehensive, high-throughput typing assays for HPV, however, are not currently available. By combining L1 consensus PCR and multiplex hybridization using a Luminex xMAP system-based suspension array, the authors developed a rapid high-throughput assay, the HPV DNA suspension array (HPV-SA), capable of simultaneously typing 26 HPVs, including 18 high-risk HPV genotypes and eight low-risk HPV genotypes. The performance of the HPV-SA applied to 26 synthetic oligonucleotide targets was evaluated. The HPV-SA system perfectly discriminated 18 high-risk HPV targets from eight low-risk HPV targets. To assess the clinical applicability of the assay, the HPV-SA was performed with 133 MY09/MY11 primer set-mediated PCR (MY-PCR)-positive clinical specimens; of the 133 samples, 121 were positive by HPV-SA. Both single and multiple types were easily identified. The authors believe that improvement of the assay may be useful for epidemiological studies, cancer-screening programmes, the monitoring of therapeutic interventions, and the evaluation of the efficacy of HPV vaccine trials.

Objective: Persistence of high-risk HPV infection is known to be the major cause of cervical cancer. It is important to differentiate the genotype of HPV infection, whether it is high, intermediate or low risk. The aim of this study was to assess the prevalence of high-risk HPV types among Indonesian women with negative VIA. Method: We analyzed cervical swabs from 1,214 patients with negative VIA. By using INNO-Lipa HPV DNA test, we detected the HPV DNA and its genotype. Result: From the 1,214 women with negative VIA, 48 (3.95%) samples were confirmed to have positive HPV DNA by using PCR and electrophoresis. However, hybridization test were not able to detect HPV genotypes in 9 samples. These 9 samples were tested again with PCR and electrophoresis and resulted in negative HPV DNA. Among the remaining 39 samples (3.21%), we detected 19 types of HPV, consisting of 13 types of high-risk HPV, 5 types of low-risk HPV, and 1 type of unknown HPV (type X). Conclusion: Among patients with negative VIA, 3.21% was found to be positive for HPV DNA. From this percentage, the prevalence of high-risk HPV is higher than the low-risk and unknown HPV. Therefore we cannot ignore results of negative VIA, particularly in highrisk group, because there is a slight possibility that presence of HPV can be identified, especially the high risk ones which have a tendency to be persistent. We support the importance of HPV DNA test as cervical cancer screening method. [Indones J Obstet Gynecol 2014; 3: 153-156] Keywords: cervical cancer, high-risk HPV, negative VIA

5525 Background: The role of human papillomavirus (HPV) in development from oncogenic infection to invasive cervical cancer (ICC) has been well established. However, the association of HPV genotypes and prognosis of ICC is controversial. Methods: We identified all ICC diagnosed in Sweden during the years 2002-2011 (4254 confirmed cases after clinical and histo-pathological review), requested all archival formalin-fixed, paraffin-embedded blocks and subjected them to comprehensive HPV genotyping. Twenty out of twenty-five archives agreed to the study, contributing a total of 2845 confirmed cases with valid HPV results. Cases were followed up from date of cancer diagnosis to 31 December, 2015, migration from Sweden, or death; whichever occurred first. Five-year relative survival ratios (RSRs) were calculated and excess hazard ratios (EHRs) with 95% confidence intervals (CIs) were estimated using Poisson regression. Results: HPV was detected in 2365 tumors (83.1% of all cases). The five-year RSR by tumor HPV status was 0.54 (HPV negative), 0.76 (HPV16 positive), 0.73 (HPV18 positive), 0.72 (other high-risk HPV positive) and 0.56 (low-risk HPV positive) compared to the age-matched general female population. Compared to cases with HPV-negative tumor, a significantly lower excess mortality was seen if the tumor was positive for HPV16 (EHR:0.54, 95% CI 0.44-0.65), other high-risk HPV (EHR:0.47, 95% CI 0.37-0.60), and low-risk HPV (EHR:0.48, 95% CI 0.32-0.74), after adjustment for age, time since cancer diagnosis, International Federation of Gynecology and Obstetrics (FIGO) stage, educational level and histology. However, the mortality among women with HPV18 positive tumors were not statistically significantly different from cases with HPV-negative tumors. In women with a single HPV infection of either HPV16 or HPV18, those with HPV18-positive tumors had 56% (EHR:1.56, 95% CI: 1.13-1.97) higher excess mortality compared to women with HPV16-positive tumors. Conclusions: HPV genotype in cervical cancer tumor is associated with prognosis of ICC. Single HPV18 positivity indicated a poorer prognosis than single HPV16 positivity. This could add information of value beyond the established clinical prognostic factors for women diagnosed with ICC.
