Abstract BackgroundThe 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.MethodsA 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.ResultsGenerally, 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 (Insert p value). The first four subtypes were 52 / 53 / 58 / 16, respectively. The infection rate of HPV in patients with lower genital tract inflammation was significantly higher, P = 0.000, 95% CI: 1.911 (1.416, 2.580) compared with those without lower genital tract inflammation. The results further showed that there was no significant difference between pre- and postmenopausal women in terms of HPV infection rate, 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.ConclusionsIt was concluded that whether menopause has nothing to do with HPV infection. Moreover, the infection rate of high-risk HPV increases after 65 years of age; hence the cutoff screening age should be appropriately prolonged.Trial registration: Retrospectively registered.

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.

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.

Cervical cancer is responsible for around 5% of all human cancers worldwide. It develops almost exclusively from an unsolved, persistent infection of the squamocolumnar transformation zone between the endo- and ecto-cervix with various high-risk (HR) human papillomaviruses (HPVs). The decisive turning point on the way to persistent HPV infection and malignant transformation is an immune system weakened by pathobionts and oxidative stress and an injury to the cervical mucosa, often caused by sexual activities. Through these injury and healing processes, HPV viruses, hijacking activated keratinocytes, move into the basal layers of the cervical epithelium and then continue their development towards the distal prickle cell layer (Stratum spinosum). The microbial microenvironment of the cervical tissue determines the tissue homeostasis and the integrity of the protective mucous layer through the maintenance of a healthy immune and metabolic signalling. Pathological microorganisms and the resulting dysbiosis disturb this signalling. Thus, pathological inflammatory reactions occur, which manifest the HPV infection. About 90% of all women contract an HPV infection in the course of their lives. In about 10% of cases, the virus persists and cervical intra-epithelial neoplasia (CIN) develops. Approximately 1% of women with a high-risk HPV infection incur a cervical carcinoma after 10 to 20 years. In this non-systematic review article, we summarise how the sexually and microbial mediated pathogenesis of the cervix proceeds through aberrant immune and metabolism signalling via CIN to cervical carcinoma. We show how both the virus and the cancer benefit from the same changes in the immune and metabolic environment.

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.

Human papillomavirus (HPV) is the most common sexually transmitted infection 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. 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 a commercial system. 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 reported use 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. 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.

Abstract In this study, a total of 301,880 woman were recruited from 4 different regions of China. The overall prevalence of HPV was 18.01 %. The high-risk HPV infection rate was 79.14%, the low-risk HPV infection rate was 12.56 %, and the mixed HPV infection rate was 8.30%. The most common 4 HR HPV subtypes were HPV-52, 16, 58 and 53, which accounted for 20.49 %, 19.93 %, 14.54 % and 10.01 %. In LR HPV genotype, HPV-6 ranked the highest (28.17 %), followed by HPV-81 (9.09 %) and HPV-11 (3.78 %). HPV genotype subgroup analysis also showed that single-type infections had the highest prevalence rate (77.26 %) among HPV positive individuals. Among muti-infection genotype, double infection was the most common with frequencies of 76.04 %. This large report showed that the overall prevalence of HPV was high in China, whose distribution exhibits different patterns across different particular age and regions. Viral genotypes HPV 53, 6 were frequently detected in this population, which is worth of significant clinical attention.

Objective To compare the prevalence of abnormal anal cytology and high-risk HPV among women with a recent history of HPV-related genital neoplasia to women without a history of HPV-related genital neoplasia. Methods: A cross-sectional pilot study was performed. Women with a history of high-grade cervical, vulvar, or vaginal dysplasia or cancer within the past 2 years were eligible for the exposed group. Women without a history of high-grade anogenital dysplasia or cancer were eligible for the control group. Anal cytology and HPV genotyping were performed after informed consent was obtained. Results: 127 women were enrolled in the exposed group and 45 in the control group. The control group was slightly older and less likely to be current smokers. There was no difference between groups in history of anal intercourse. Forty-four per cent of the exposed group had abnormal anal cytology compared with 21.6% of the control group (P = 0.03). High-risk HPV was detected in the anal canal of 6 in the exposed group compared with none in the control group (P = 0.2). Fourteen per cent of the anal cytology results were read as insufficient in both groups. HPV results were insufficient in 29.2% of exposed versus 43.5% of control (P = 0.2). Conclusions: Women with a history of lower genital tract dysplasia are more likely to have a positive anal cytology result compared with women without a history. Additional information is needed to determine the best method of anal cancer screening among women with a history of lower genital tract dysplasia.

This article is a preliminary investigational study that is aimed at giving hints about the interesting biomarkers involved in the transition process from low-grade cervix lesion to invasive cervical cancer. Our study focuses on the risk factors and tumour molecular changes in one patient. First in 1986, she was diagnosed a preinvasive cervix lesion. Then, 16 years later, she was diagnosed an invasive cervical cancer. The 2002 diagnosis was a squamous cell carcinoma of the cervix, stage IIIB (FIGO), whereas in 1986, she had been diagnosed a high-grade squamous intraepithelial cervical lesion. Retrospectively, the analysis of samples of preneoplastic lesions and invasive cervical cancer confirmed the histopathological diagnoses and detected the presence of HPV type and HPV-16 variants, as well as the overexpression of proteins such as hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1. Finally, the Arg72Pro polymorphism was detected in TP53. The role of high-risk HPV and HPV-16 variants and of hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1 variations seemed confirmed in the development and progression of cervical cancer. As a result, analyzing the molecular changes in one and same tumour that progresses from a low-grade cervix lesion to invasive cervical cancer could provide valuable information in order to improve detection, diagnosis, and treatment in the future.

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.

Objective: To investigate the epidemiological characteristics and genotypes of human papillomavirus (HPV) infection in Mianyang. Methods: The cervical samples of 27,040 patients, who visited the Department of Gynecology of The Third Hospital of Mianyang from January 2018 to January 2020, were collected. Results: The HPV-positive infection rate was 21.40% (5,787/27,040); the single HPV infection rate was 72.04% (4,169/5,787); the double HPV infection rate was 19.73% (1,142/5,787); the triple and above HPV infection rate was 8.22% (476/5,787); the top five high-risk HPV subtypes with the highest infection rates were HPV52, 16, 58, 53, and 51, while the top five low-risk HPV subtypes with the highest infection rates were HPV81, 42, 43, 6, and 11; there were significant differences in the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate among different age groups (P < 0.05). Conclusion: The HPV infection rate in Mianyang was 21.4%, in which the majority of the cases were single infection; the high-risk HPV subtypes were HPV52, 16, 58, 53, and 51; the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate were high in the middle but low at both ends in the context of age distribution; the top three age groups with the highest infection rates were 45-49, 40-44, and 30-34.
