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.

Introduction: Infections caused by Chlamydia trachomatis (CT) and Human Papilloma Virus (HPV) are among the most prevalent sexually transmitted infections (STIs) worldwide. CT infection in women living with the human immunodeficiency virus (HIV) can facilitate HIV transmission by increasing HIV shedding in cervicovaginal secretions. The prevalence of Human papillomavirus (HPV) infection is higher in women living with HIV when compared to HIV-negative women, even when comparing those with the same sociodemographic characteristics. Generally, they have a high viral load and a higher persistence of viral infection, which increases the risk of developing premalignant and malignant lesions in the lower genital tract. Objective: To evaluate the frequency of CT and High-Risk HPV (HR-HPV) infection among women living with HIV and the association with sociodemographic, behavioral and clinical characteristics. Methods: Cross-sectional study carried out with a population of 66 non-pregnant women aged between 18 and 70 years living with HIV and/or acquired immunodeficiency syndrome (AIDS) at the Hospital Universitário Antônio Pedro, Universidade Federal Fluminense (UFF), Niterói (RJ), Brazil, between the period of March 1, 2018 and October 31, 2018. A standardized questionnaire was applied including sociodemographic and behavioral characteristics, and clinical information (use of oral contraceptives, Antiretroviral Therapy (ART), cluster of differentiation 4 (CD4) cell count, and viral load). Endocervical samples were collected for CT (COBAS 4800® system, Roche) and HPV (COBAS® HPV test, Roche) detection. Fisher's Exact Test was used to assess the association between variables. Regression analyses were performed using the logistic model in order to identify the factors associated with the outcomes of interest. Results: A frequency of 1.5% for CT and 21.2% for HR-HPV was found. Age was the single factor that presented statistical significance associated with HR-HPV infection. Conclusion: Our study showed that some women living with HIV promote risky behavior which could facilitate the acquisition of other STIs, such as HPV and CT infection. Some of them, with detected viral load, were not using condoms even with HIV-negative partners. These results may suggest that in addition to treatment and follow-up of women living with HIV, STIs counseling and guidance may play an important role in the control of STIs in this population.

Introduction: Human immunodeficiency virus (HIV) is associated with inflammation. An association between vitamin D deficiency and inflammation also exists. Our study attempts to examine whether there may be a relationship between vitamin D and HIV viral load (HIV RNA) by: 1) characterizing the distribution of 25-hydroxyvitamin D (25-OHD), and 2) determining if 25-OHD is independently associated with HIV RNA. Methodology: A cross-sectional study among HIV-infected adults was conducted. Demographics, clinical / social / HIV characteristics and data on antiretroviral therapy were collected by questionnaire, medical records and laboratory testing. All patients provided blood samples. Bivariate and multivariate analyses were conducted to quantify the relationship between vitamin D and HIV RNA. Results: Among the 564 patients, the median (interquartile range, IQR) 25-OHD value was 24.42 (16.22 – 34.10) ng/mL. The mean (standard deviation, SD) log-HIV RNA was 3.51 (1.11) copies/mL. There were 304 patients (53.9%) with an undetectable HIV RNA (< 500 copies/mL). In the bivariate analyses, no differences were observed between patients with and without an undetectable HIV RNA in mean (SD) 25-OHD, 25-OHD insufficiency (< 30 ng/mL), or 25-OHD deciles. In the log-binomial regression analyses, there was no association between 25-OHD and an undetectable HIV RNA (prevalence ratio: 1.00, 95% confidence interval: 0.99 – 1.01, p = 0.67). Conclusions: No relationship was observed between 25-OHD and HIV RNA among HIV-infected patients in Kazakhstan.

AbstractThis study aims to investigate the prevalence and genotype distribution of anal human papillomavirus (HPV) infection among men with different sexual orientations with or without human immunodeficiency virus (HIV) in China. A cross-sectional study was conducted during 2016–2017 in Taizhou City, Zhejiang Province. Convenient sampling was used to recruit male participants from HIV voluntary counselling and testing clinics and Center for Disease Control and Prevention. A face-to-face questionnaire interview was administered and an anal-canal swab was collected for HPV genotyping. A total of 160 HIV-positive and 113 HIV-negative men participated in the study. The prevalence of any type HPV was 30.6% for heterosexual men, 74.1% for homosexual and 63.6% for bisexual men among HIV-positive participants, while the prevalence was 8.3%, 29.2% and 23.8% respectively among HIV-negatives. The most prevalent genotypes were HPV-58 (16.9%), HPV-6 (15.6%) and HPV-11 (15.0%) among HIV-positive men, and were HPV-16 (4.4%), HPV-52 (4.4%) and HPV-6 (3.5%) among HIV-negative men. Having ever had haemorrhoids and having ever seen blood on tissue after defaecation was associated with HPV infection. One-fourth of the HPV infections in this study population can be covered by the quadrivalent vaccine in market. The highly prevalent anal HPV infection among men especially HIV-infected men calls for close observation and further investigation for anal cancer prevention.

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.

Lunula is the white, half-moon shaped area seen in proximal ends of some nails. Though a few studies have described the nail changes that can occur in association with HIV infection, none of these paid much attention to lunula. Aims and Objectives. To study the lunula in fingernails among HIV infected patients. Materials and Methods. An observational, cross-sectional study to record presence of lunula in 168 HIV-positive patients and compare it with age and sex matched 168 healthy HIV-negative control. Anolunula (absence of lunula) in HIV-positive patients was correlated with CD4 counts, stages of HIV infection, time since patient was diagnosed as HIV-positive, and status of antiretroviral therapy. Results. Anolunula was present in significantly more fingernails in HIV-positive patients compared to HIV-negative controls. There was a highly significant difference for total anolunula (anolunula in all fingernails) in study and control group. Incidence of total anolunula was directly proportional to the stage of HIV infection, increasing progressively as the HIV infection advances from stage 1 to stage 4. Conclusion. Absence of lunula is related to not only HIV infection per se but also the stages of HIV infection.

PURPOSE: To morphometrically quantify CD1a+ dentritic cells and DC-SIGN+ dendritic cells in HIV-positive patients with anal squamous intraepithelial neoplasia and to evaluate the effects of HIV infection, antiretroviral therapy and HPV infection on epithelial and subepithelial dendritic cells. METHODS: A prospective study was performed to morphometrically analyze the relative volume of the dendritic cells and the relationship between anal intraepithelial neoplasia and cancer in HIV-positive patients from the Tropical Medicine Foundation of Amazonas, Brazil. All patients were submitted to biopsies of anorectal mucosa to perform a classic histopathological and immunohistochemical analysis, employing antibodies against CD1a and DC-SIGN for the morphometric quantification of dendritic cells. RESULTS: HIV-negative patients displayed a CD1a DC density significantly higher than that of HIV-positives patients (3.75 versus 2.54) (p=0.018), and in patients with severe anal intraepithelial neoplasia had correlated between DC CD1a density with levels of CD4 + cells (p: 0.04) as well as the viral load of HIV-1 (p: 0.035). A not significant rise in the median density of CD1a+ DC was observed in the HIV positive/ HAART positive subgroup compared to the HIV positive/ HAART negative subgroup. The CD1a+ DC were also significantly increased in HIV-negative patients with anorectal condyloma (2.33 to 3.53; p=0.05), with an opposite effect in HIV-positive patients. CONCLUSIONS: Our data support an enhancement of the synergistic action caused by HIV-HPV co-infection on the anal epithelium, weakening the DC for its major role in immune surveillance. Notoriously in patients with severe anal intraepithelial neoplasia, the density of CD1a+ epithelial dendritic cells was influenced by the viral load of HIV-1. Our study describes for the first time the density of subepithelial DC-SIGN+ dendritic cells in patients with anal severe anal intraepithelial neoplasia and points to the possibility that a specific therapy for HIV induces the recovery of the density of epithelial DC.

Background: The relationship among HIV, HPV, and development of CIN is complex and incompletely understood. Present study is undertaken to find out the prevalence and relationship of abnormal cervical cytology and HPV infection in HIV positive women.Methods: This was a cross-sectional, case control study conducted on 95 HIV seropositive and 95 seronegative women. Specimen was collected from the cervix for HPV DNA testing, subtyping and cytology.Results: HPV DNA positivity was higher in seropositive group (18.6% vs. 7.4%). Premalignant conditions were found only in seropositive group. At CD4 count <249 HPV DNA positivity was 53%, at 250-499 the percentage of HPV DNA positivity was 31% and at >500 HPV DNA positivity was 19%.Conclusions: Prevalence of abnormal cytology and HPV DNA positivity is higher amongst HIV positive women and there is an association between HPV DNA positivity with lower CD4 counts.
