CONTEXT: Many factors like exposure to UV radiation, climatic conditions, genetic predisposition, immunological state and, more recently, the presence of HPV have been implicated in the genesis of some lesions of the conjunctiva, especially the carcinoma. OBJECTIVE: To evaluate the presence of HPV DNA in acquired lesions of the conjunctiva and in normal mucosa. TYPE OF STUDY: Cross-sectional study. SETTING: A public university referral center (the Ophthalmology Service of the A.C. Camargo Hospital - A. Prudente Foundation, São Paulo). PARTICIPANTS: Thirty patients with acquired lesions of the conjunctiva and 60 matched controls (by age and sex) were evaluated in this study, from June 1993 to March 1995. PROCEDURES: The detection of HPV DNA in the normal conjunctiva and in acquired lesions was done by the PCR technique and dot blot hybridization. The material was collected by scraping the normal mucosa and the surface of the lesions. A fragment of fresh frozen tissue and paraffin embedded specimens of each lesion were also included. MAIN MEASUREMENTS: The association between the HPV infection and the presence or absence of conjunctival lesions. RESULTS: Sequences of HPV DNA were detected in 4 of the 31 lesions evaluated (12.9%) and in the healthy mucosa of one individual of the control group (1.6%). HPV type 16 was detected in 2 carcinomas and in the normal mucosa of one individual of the control group. HPV type 11 was demonstrated in 2 papillomas of one patient with lesions in both eyes. CONCLUSIONS: The low frequency of HPV DNA found in the lesions of this sample and the detection of the viral genome in the normal mucosa indicate that there is a weak possibility of association between HPV infection and the carcinoma of the conjunctiva.

AbstractThis cross-sectional study investigated the characteristics of cervical HPV infection in Changsha area and explored the influence of Candida vaginitis on this infection. From 11 August 2017 to 11 September 2018, 12,628 outpatient participants ranged from 19 to 84 years old were enrolled and analyzed. HPV DNA was amplified and tested by HPV GenoArray Test Kit. The vaginal ecology was detected by microscopic and biochemistry examinations. The diagnosis of Candida vaginitis was based on microscopic examination (spores, and/or hypha) and biochemical testing (galactosidase) for vaginal discharge by experts. Statistical analyses were performed using SAS 9.4. Continuous and categorical variables were analyzed by t-tests and by Chi-square tests, respectively. HPV infection risk factors were analyzed using multivariate logistic regression. Of the total number of participants, 1753 were infected with HPV (13.88%). Females aged ≥ 40 to < 50 years constituted the largest population of HPV-infected females (31.26%). The top 5 HPV subtypes affecting this population of 1753 infected females were the following: HPV-52 (28.01%), HPV-58 (14.83%), CP8304 (11.47%), HPV-53 (10.84%), and HPV-39 (9.64%). Age (OR 1.01; 95% CI 1–1.01; P < 0.05) and alcohol consumption (OR 1.30; 95% CI 1.09–1.56; P < 0.01) were found to be risk factors for HPV infection. However, the presence of Candida in the vaginal flora was found to be a protective factor against HPV infection (OR 0.62; 95% CI 0.48–0.8; P < 0.001). Comparing with our previous study of 2016, we conclude that the subtype distribution of HPV infection is relatively constant in Changsha. Our data suggest a negative correlation between vaginal Candida and HPV, however, more radical HPV management is required in this area for perimenopausal women and those who regularly consume alcohol.

AbstractThis study evaluated human papillomavirus’s (HPV) role in pterygium pathogenesis, its autoinoculation from genitalia to ocular surface, potential cytokines involved, and crosstalk cytokines between pterygium and dry eye (DE). This cross-sectional study enrolled 25 healthy controls (HCs) and 116 pterygium patients. Four subgroups of pterygium and DE were used in cytokine evaluations. Conjunctival and pterygium swabs and first-void urine samples (i.e., genitalia samples) were collected for HPV DNA detection using real-time polymerase chain reaction. Tear cytokines interleukin (IL)-6, IL-18, and vascular endothelial growth factor (VEGF) in tears were evaluated. No HPV DNA was detected in conjunctival or pterygium swabs. No association was found between HPV DNA in urine samples and that from conjunctival or pterygium swabs. Tear VEGF levels were significantly higher in pterygium patients than in HCs, with no markedly different levels between primary and recurrent pterygia. Tear IL-6, IL-18, and tear VEGF were significantly higher in participants with DE, regardless of pterygium status. In conclusion, HPV infection was not a pathogenic factor of pterygia. The hypothesis of HPV transmitting from the genitals to ocular surfaces was nullified. Tear VEGF was involved in both pterygia and DE, whereas tear IL-6 and IL-18 played roles only in DE.

INTRODUCTION:HTLV-1 infection increases susceptibility to other infections. Few studies have addressed the co-infection between HPV and HTLV-1 and the immune response involved in this interaction. The aim of this study was to determine the prevalence of cervical HPV infection in HTLV-1-infected women and to establish the risk factors involved in this co-infection. METHODS: A cross-sectional study was carried out in Salvador, Brazil, between September 2005 and December 2008, involving 50 HTLV-1-infected women from the HTLV Reference Center and 40 uninfected patients from gynecological clinic, both at the Bahiana School of Medicine. HPV infection was assessed using hybrid capture. HTLV-1 proviral load was quantified using real-time polymerase chain reaction (PCR). RESULTS: The mean age of HTLV-1-infected women (38 ± 10 years) was similar to that of the control group (36 ± 13 years). The prevalence of HPV infection was 44% in the HTLV-1-infected group and 22.5% in uninfected women (p = 0.03). HTLV-1-infected women had lower mean age at onset of sexual life (17 ± 3 years versus 19 ± 3 years; p = 0.03) and greater number of lifetime partners compared with the control group (4 ± 3 versus 2 ± 1; p < 0.01). In the group of HTLV-1-infected patients, there was neither difference in HTLV-1 proviral load between HPV-infected women and the uninfected. CONCLUSIONS: The prevalence of HPV infection was higher in HTLV-1-infected women. Further studies should be performed to evaluate the progression of this co-infection.

Objective: This study sought to identify the presence of HPV infection and the risk factors related to susceptibility to cervical cancer in asymptomatic women. Methods: It is a cross-sectional study with 428 users attended Basic Health Units, in Arapiraca, Alagoas, Brazil. Sociodemographic, behavioral variables, and cytopathological reports were collected. Molecular detection of the HPV virus was performed by Nested-PCR. Statistical analysis was conducted with SPSS version 22.0. Results: A total of 428 women were studied, HPV DNA detected in 39.2% (n = 168), with a mean age of 41 years old. There was an association of HPV with use of oral contraceptives (p <0.016) and alcoholism (p <0.038). It was showed a higher frequency of positive HPV in women older than 25 years old (88.7%), up to 5 sexual partners (93.4%), up to 3 pregnancies (71.4%), and with the cytopathologic results within the limits of normality (61.9%). HPV was identified in 40.3% (104/258) of the women with results within the limits of normality. Conclusion: Our results suggest that the use of oral contraceptives and alcoholism may be considered as possible risk factors related to cervical oncogenesis. With this, it is necessary to propose interventions aimed at the health education of this population, actions of prevention, and early detection.

Objective. To estimate HPV prevalence among pregnant women from Ribeirão Preto, Brazil, and the possible influence of HIV-1 infection on this prevalence.Methods. A cross-sectional study with 44 HIV-positive and 53 HIV-negative pregnant women was conducted. Cervicovaginal specimens were obtained from all women during gynecologic exam. HPV DNA, low and high risk HPV types, was detected using conventional PCR. Statistical analysis used Student'st-test, Mann-Whitney test, Fischer's Exact test, and prevalence ratios with 95% confidence interval.Results. HIV-positive pregnant women had higher proportion of HPV infection than HIV-negative pregnant women (79.5% versus 58.5%;P<.05). HPV positivity prevalence ratio for HIV-positive women was 1.36 (95% CI 1.04–1.8;P=.03). There was significant association between HIV viral load levels and HPV positivity (P<.05).Conclusions. Our results demonstrate higher HPV positivity in HIV-infected pregnant women. Higher values of HIV viral load were associated with HPV positivity.

Background.HIV-infected adolescents may be at higher risk for high-grade cervical lesions than HIV-uninfected adolescents. The purpose of this study was to compare the prevalence of high-risk HPV (HR-HPV) infections and Pap smear abnormalities between these two groups.Methods.In this cross-sectional study, we compared the HPV DNA and Pap smear results between 35 HIV-infected and 50 HIV-uninfected adolescents in order to determine the prevalence of HR-HPV genotypes and cervical cytological abnormalities. Comparisons were made using Pearsonχ2and independent-samplest-tests analyses, and associations between demographic and behavioral characteristics and HPV infections were examined.Results.HIV-infected participants were more likely to be infected with any HPV (88.6% versus 48.0%;P<0.001) and with at least one HR-HPV (60.0% versus 24.0%;P=0.001), and to have multiple concurrent HPV infections (68.6% versus 22.0%;P<0.001). HPV 16 and 18 were relatively underrepresented among HR-HPV infections. Abnormal Pap test results were more common among HIV-infected participants (28.8% versus 12.0%;P=0.054). A history of smoking was associated with HR-HPV infection.Conclusions.HIV-infected adolescents have an increased risk of infection with HR-HPV and of Pap test abnormalities. The majority of HR-HPV infections among our participants would not be prevented by the currently available vaccinations against HPV.

Abstract Background The natural history of human papillomavirus (HPV) is influenced by vaginal microenvironment disorders, such as bacterial vaginosis (BV). The objective of this study was to assess the epidemiology of HPV combined with BV prevalence among Chinese women aged 20–35 years. Methods A total of 2000 sexually active women aged 20–35 years voluntarily enrolled in this study and underwent a ThinPrep cytologic test and PCR-reverse dot blot human papillomavirus genotyping (PCR-RDB HPV test). BV was diagnosed if clue cells were observed (20% more than epithelial cells). Results The overall HPV infection rate in this population was 16.2% (324/2000). Compared with HPV-negative individuals, BV prevalence was higher in the High-risk human papillomavirus (HR-HPV) (5.9% vs. 3.1%, P < 0.001). BV and HPV-51, -52 infection were more commonly associated with each other. In patients with cervical lesions (≥ CIN 1), the BV prevalence rate was higher than in patients with negative for intraepithelial lesion or malignancy (NILM) (11.9% vs. 3.8%, P = 0.002). Conclusion BV was found to be related to HPV-51, -52 infections and cervical lesions. To better manage HPV infected population, more attention should be paid to the prevention and proper treatment of BV.

Abstract PURPOSE: Dynamic thiol disulfide homeostasis (TDH) is critical in cervical carcinogenesis at HPV infection as a sign of antioxidant consumption native and total thiol levels decrease in progress to cervical intraepithelial lesions. TDH is the main actor in signaling pathways, apoptosis, antioxidant and detoxification reactions. In this study, we aimed to evaluate the effect of TDH intraepithelial progression of cervical precancerous lesions on HPV positive women.METHODS: This was a prospective cross-sectional study. Subjects were selected from newly diagnosed high risk HPV DNA-positive patients. TDH results were calculated as the levels of disulfide, native and total thiol, the ratios of disulfide/total thiol (SS/SH+SS), disulfide/native thiol (SS/SH) and native thiol/total thiol (SH/SH+SS).RESULTS: A total of 146 women were included in the study. Study groups were as group one; control included 66 participants, group two; HPV DNA-positive women without preinvasive cervical lesion included 30 participants and group three; HPV DNA-positive women with preinvasive cervical lesion included 50 participants. Native and total thiol levels were elevated on HPV-positive women without preinvasive cervical lesions. There were no significant differences between groups related to the ratios of SS/SH, SS/ Total SH, SH/ Total SH levels. CONCLUSIONS: HPV infection related to oxidative stress has effects on oxidant/antioxidant balance and could be demonstrated in systemic circulation by TDH parameters. Consumption of thiol substances play role in the cervical neoplastic process, replacement with antioxidants would be a treatment option for HPV infections.

Background: Uterine cervical malignancy is one of the commonly detected malignancies related to the human papillomavirus (HPV) and is increasing incidentally in developing countries. Therefore, the use of an efficient diagnostic method is required as an effectual step for cervical cancer prevention and treatment. The purpose of the study was to diagnose various types of HPV in the cervical cytology specimens in the South-East of Iran. Methods: This cross-sectional study was performed on 1079 cervical fluid cytology specimens referred for two years, between 2018-2020. Polymerase chain reaction (PCR) and hybridization (INNO-LiPA HPV Genotyping EXTRA II assay) were used to determine HPV DNA and their genotypes, respectively. Results: HPV was positive in 37.7% (407 of 1079) patients with a mean age of 34.62 ± 8.82. Among positive cases, 252 (62%) had only one HPV genotype and 155 (38.05%) had multiplex HPV genotypes, which included 94 (60.7%), 38 (24.6%), 18 (11.6%) and 5 (3.2%) cases with two, three, four and five or more genotypes, respectively. The samples with multiple strains revealed 31 HPV genotypes with the four most prevalent being HPV6 (14.7%), HPV16 (10.9%), HPV53 (9.6%) and HPV51 (5.9%). Conclusion: HPV infection is the main health challenge for women that requires improved health service programs and appropriate epidemic vaccination.

ObjectivesMen who have sex with men (MSM) have an increased risk of human papillomavirus (HPV) infection and related diseases compared with men who have sex exclusively with women. From April 2018, there has been a phased roll-out of HPV vaccination offered to MSM aged up to 45 years old who are attending sexual health clinics and HIV clinics in England. The vaccine is most effective if delivered prior to HPV infection. We estimated the proportion of MSM with no current vaccine-type infection and no serological evidence of prior infection, in a study undertaken prior to vaccine introduction.MethodsWe conducted a cross-sectional study among 484 MSM aged 18–40 years old who attended a sexual health clinic in London between 2010 and 2012. We estimated the prevalence of current and past infection by testing for HPV DNA in anogenital samples and for serum antibodies to HPV16 and HPV18.ResultsThe median age was 30 years (IQR 25–35). The prevalence of HPV16 and HPV18 DNA was 13.2% and 6.2%, respectively. Seropositivity for HPV16 and HPV18 was 28.5% and 17.1%, respectively, with 11.4% seropositive for both types. Seropositivity for the same HPV type was strongly associated with anogenital DNA detection. 279 MSM (57.6%) tested negative for both HPV16 and HPV18 serology and were DNA negative for these two types; only 5 MSM (1.0%) were seropositive and DNA positive for both HPV types.ConclusionsThis is the first study to determine both the prevalence of HPV DNA in anogenital samples and HPV seroprevalence among MSM attending a sexual health clinic in the UK. Over half of MSM in this study had no evidence of a previous or current infection with either of the high-risk HPV types included in the quadrivalent vaccine, which supports the rationale for opportunistic HPV vaccination of MSM attending sexual health clinics.
