Comparative evaluation of HPV genotyping: A study on the performance concordance between Anyplex II HPV28 detection and Linear Array genotyping tests in nationwide studies in Brazil.

BACKGROUND: Advances in laboratory techniques for HPV diagnosis necessitate a thorough assessment of the efficiency, replicability, sensitivity, and specificity of those methods. This study aims to validate and compare HPV detection/genotyping using the Anyplex™ II HPV28 Detection assay (Seegene) assay and the Linear Array HPV Genotyping test (Roche Diagnostics) on genital samples for use in epidemiological studies. METHODS: From 6,388 penile and cervical DNA samples collected in the POP-Brazil, 1,745 were randomly selected to be included in this study. The samples were submitted to HPV detection and genotyping following the manufacturers' protocols. DNA was genotyped using the Anyplex™ II HPV28 Detection kit (Seegene), and the results were compared to those obtained using the Linear Array HPV Genotyping test (Roche Diagnostics). Concordance of HPV genotyping results was assessed by the percentage agreement and Cohen's kappa score (κ). RESULTS: The agreement between the two methodologies was deemed good for HPV detection (κ = 0.78). Notably, Anyplex™ II HPV28 demonstrated enhanced capability in detecting a broader spectrum of genotypes compared to Linear Array. CONCLUSION: Anyplex™ II HPV28 exhibited comparable results to the Linear Array assay in clinical specimens, showcasing its potential suitability for a diverse array of research applications requiring the detection and genotyping of HPV. The study supports the utility of Anyplex™ II HPV28 as an effective tool for HPV screening in epidemiological studies, emphasizing its robust performance in comparison to established diagnostic tests.

HPV-DNA test access based on self-collection of vaginal samples from women living with HIV/AIDS: pilot implementation in Brazil / Autocoleta vaginal por mulheres vivendo com HIV/AIDS para testagem de HPV-DNA: implantação piloto no Brasil

Introduction: Women living with HIV/AIDS have a higher frequency of anogenital neoplasms resulting from human papillomavirus (HPV) infection. The World Health Organization recommends that cervical cancer screening uses molecular tests that amplify viral genetic material, such as HPV-DNA. In addition to collection by health professionals, self-collection of vaginal samples is a useful tool for expanding access to testing. Objective: To describe the results of the pilot study that evaluated the acceptability of self-collection of vaginal samples and the applicability of offering HPV-DNA tests with self-collection of vaginal samples for women living with HIV/AIDS in Brazil. Methods: Descriptive cross-sectional study involving women living with HIV/AIDS treated in eight HIV-specialty healthcare facilities distributed in all regions of the country from May 2021 to May 2022 and a central laboratory. Vaginal self-collection was offered, and participants were interviewed about sociodemographic data and impressions of self-collection. Results: In total, 1,919 women living with HIV/AIDS with an average age of 45 years participated in the study. Some type of HPV was detected in 66% (1,267) of cases. The majority (71.9%) said they preferred self-collection to sample collection by health care professionals. Only 53.8% of participants underwent cytology at the appropriate frequency, as recommended by the protocol. Conclusion: The results may support the implementation of molecular biology tests to detect HPV in women living with HIV/AIDS, including the possibility of vaginal self-collection, promoting increased access to cervical cancer screening.

Detection of HPV DNA in vaginal samples self-collected by women living with HIV treated through the Brazilian public health system: Prevalence and analysis of risk factors.

BACKGROUND: Women living with human immunodeficiency virus (HIV) (WLWH) are more likely to be infected with the oncogenic human papillomavirus (HPV). We assessed the prevalence of high-risk (HR) (16/18/31/33/35/39/45/51/52/56/58/59/68/73/82), probable high-risk (pHR) (26/53/66), and low-risk (LR) (6/11/40/42/43/44/54/61/70) HPV types and their associated risk factors. METHODS: This cross-sectional study of WLWH aged 18-64 years included one laboratory and eight HIV-specialty healthcare facilities in the pilot network. Descriptive statistics were used to assess sociodemographic and behavioral characteristics. Adjusted analyses were conducted to evaluate risk factors associated with HR and/or pHR HPV infection in WLWH. RESULTS: From May/2021 to May/2022, 1,914 (92.5%) WLWH participated in the pilot study and had valid HPV-DNA results of self-collected vaginal samples. The median age of the participants was 45 years, 60.1% had ≥ 9 years of schooling, 80.5% were ≤ 18 years at first sexual intercourse, and 51.7% had > 4 sexual partners throughout life. The prevalence of any HPV type, HR HPV, pHR HPV, and LR HPV was 65.8%, 49.6%, 16.7%, and 40.0%, respectively. Age was inversely associated with pHR and/or HR-HPV (p < 0.001), and education level was inversely associated with HR-HPV (p = 0.003) types. Any HR or pHR was associated with being single (p = 0.029) and exchanging sex for drugs (p = 0.037). CONCLUSIONS: The prevalence of HPV, especially HR HPV, among WLWH is high in Brazil, highlighting the need for HPV screening in this population. Self-collection of vaginal samples is an important strategy for increasing testing access.

Adequacy of prenatal care and associated factors in the State of Rio Grande do Sul, Brazil

ABSTRACT OBJECTIVE This study aims to assess the degree of adequacy of prenatal care (PNC) in the state of Rio Grande do Sul (RS) and in its 7 macro-regions considering the time of PNC initiation and the number of appointments attended. It also aims to verify the mode of delivery prevalence and the factors associated with PNC adequacy by mode of delivery. METHODS Sub analysis from a cross-sectional study conducted among 13,432 childbearing women aged 15-49 years assisted in 66 maternity hospitals of the Unified Health System (SUS) and private associated facilities from September 2017 to October 2019. A standardized form was used to collect sociodemographic data, and information about PNC and delivery from the childbearing women's prenatal cards, hospital records, and medical reports. RESULTS The PNC coverage was (98.4%), but only 57.5% of the participants had an adequate PNC defined as the one initiated until the 12th gestational week, with attendance of at least 6 appointments. The cesarean rate was 57.2%. Among women who performed vaginal delivery, multivariate analysis showed that for each 1-year increase in the age of the parturient, the chance of having an adequate PNC increased by 5%. White parturients with higher education and fewer deliveries residing in the macro-region of Valleys were more likely to have an adequate PNC when compared with non-white parturients, who were illiterate and/or had incomplete elementary school, with 3 or more deliveries and who resided in other macro-regions. During pregnancy, 96.0% of the women performed at least one anti-HIV test, 55.8% a rapid test for syphilis, and 75.0% a Venereal Disease Research Laboratory test (VDRL). CONCLUSIONS Despite the almost universal PNC coverage in RS, the PNC offered by the SUS was adequate for just half of the population, therefore public health policies targeted at women receiving care in this setting shall be revisited.

Gonorrhea prevalence in adults in Brazil: Spectrum-STI trend estimation, 2000-2020

ABSTRACT Background: Gonorrhea is not a notifiable disease in Brazil, and the national health information system does not collect data on reported cases or infection prevalence. Methods: We compiled published data on gonorrhea prevalence in Brazil from cross-sectional surveys and clinical trials between 2000 and 2020. The study entry criteria included a sample size of 50 or more, and Neisseria gonorrhoeae infection detected in urine, urethral, anal, or cervicovaginal specimens using either Nucleic Acid Amplification Test or culture. Gonorrhea prevalence trends between 2000 and 2020 were generated using Spectrum-STI, a statistical trend-fitting model. Results: Forty-five studies with 59 gonorrhea prevalence data points were identified. Fifty data points were for women and represented 21,815 individuals, eight for men encompassing a total of 4,587 individuals, and one for transgender people comprising 345 individuals. The Spectrum-STI estimate for the prevalence of urogenital infection with gonorrhea in women 15-49 in 2020 was 0.63% (95% confidence interval (CI): 0.13-2.23) and was lower than the 1.05% estimated value for 2000 (95% CI: 0.36-2.79). The corresponding figures for men were 0.70% (95% CI: 0.16-2.44) and 1.14% (95% CI: 0.34-3.15). Anal prevalence estimates could not be generated because of insufficient data (three data points). Conclusions: These results suggest that the overall prevalence of genitourinary gonococcal infections in Brazil is less than 1%. Data on gonorrhea prevalence in men and in populations at increased STI vulnerability are limited.

Sexual practices and HPV infection in unvaccinated young adults.

The present study aimed to evaluate the association of genital and oral HPV infection among different sexual practices in both sexes. In total, 6388 unvaccinated men and women aged 16-25 years from all state capitals of Brazil were enrolled in through primary care services between September 2016 and November 2017. Genital and oral HPV genotyping was performed using the Roche Linear Array. Poisson regression analysis with robust variance was conducted to examine factors associated with overall HPV infection. A higher prevalence of genital HPV was found in women who practiced oral sex (57.85%) and in men who practiced all types of sex (65.87%). However, having more sexual partners and being younger were more important than the type of sex practiced. HPV 6 (7.1%) and 16 (10.5%) were significantly more prevalent in women who practiced oral sex, while HPV 6 (23.96%) and 11 (21.49%) were more prevalent in men who practiced anal sex. The type of sex was not associated with oral HPV prevalence. Genital and oral HPV infection were not associated by different sexual practices in the studied population.

The fight against sexually transmitted infections cannot stop in the COVID-19 era: a brazilian experience in online training for sexually transmitted infections guidelines / A luta contra as infecções sexualmente transmissíveis não pode parar na era COVID-19: experiência brasileira em treinamento on-line para diretrizes em infecções sexualmente transmissíveis

Introduction: The Brazilian Ministry of Health had planned face-to-face workshops for professional training about the Clinical Protocols and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections for the year 2020. Due to the COVID-19 pandemic, the workshops were cancelled, and a new strategy was adopted: virtual meetings, called Webinars ­ Clinical Protocols and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections 2020. Objective: To report the experience at the Ministry of Health in online training about the clinical protocol and therapeutic guidelines for comprehensive care for people sexually transmitted infections for health professionals in 2020. Methods: The webinars were held in partnership with the Brazilian Society of Sexually Transmitted Diseases and the Pan American Health Organization. Each chapter of the Clinical Protocols and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections ­ 2020 was converted into a webinar, with the participation of at least three experts, two speakers, and a moderator. Results: In total, 16 webinars were presented, covering topics such as sexually transmitted infections surveillance, prevention, diagnosis, treatment, public policies, and sexual violence. The initiative had more than 77,000 hits, with an average of 4,900 hits per webinar and the topic "syphilis" being the most accessed. The event reached all 27 federative units of Brazil, as well as 27 other countries. About 500 questions were received from the audience and answered during the sessions and/or through a document published later on by the Ministry of Health. Conclusion: Given the high number of hits and inquiries received, we can conclude that health professionals remained engaged in the topic of sexually transmitted infections during the pandemic. This experience shows the great potential of innovative methods for distance learning to promote continuing education, including a series of webinars aimed at strengthening the fight against sexually transmitted infections.

Behavioral factors associated with multiple-type HPV genital infections: data from a cross-sectional study in young women in Brazil.

OBJECTIVES: To investigate the pattern of multiple human papillomavirus (HPV) infections and associated factors in young women who access the Brazilian public health care system to better understand the characteristics of multiple HPV infections, a critical issue in this era of multivalent vaccines. METHODS: This was a cross-sectional, multicenter study with sexually active unvaccinated women (16-25 years old) from 119 primary Brazilian healthcare centers between September 2016 and November 2017. Cervical samples were collected by trained health professionals, and HPV detection was performed in a central laboratory by Linear Array. RESULTS: Of the 5268 women, 33.00% (95% CI 31.07-34.92) had multiple infections. At least one type of high-risk HPV was present in 85.50% of all multiple infections. All HPV types were detected more frequently in association with other types than alone. Young individuals who were single or in a casual relationship and those who had more than one sexual partner in the past year were more likely to have multiple infections. CONCLUSIONS: In this work, a high rate of multiple HPV infections among unvaccinated young adults tended to increase due to certain risk factors. Such data can provide insight for decision makers in the development of public policies regarding HPV prevention.

Understanding the characteristics of multiple infections is critical in the era of HPV multivalent vaccines for the prevention of cervical carcinomas. Therefore, in this cross-sectional study, we aimed to investigate the pattern of multiple HPV infections and associated factors in 5,268 sexually active unvaccinated women (16­25 years old) who access the Brazilian public health care system. Cervical samples were collected by trained health professionals, and HPV detection was performed in a central laboratory by Linear Array. A total of 33.00% (95% CI 31.07­34.92) had multiple infections (60.43% of the HPV-positive sample). The number of HPV types in a multiple infection ranged from 2 to 14 different types. The viral types more frequently identified were HPV 16 and 52. All HPV types were detected more frequently in association with other types than alone. The incidence of multiple infections was 1.29 times higher in single than in married or cohabitating participants. Women who had two or more partners in the last year also had higher rates of multiple infections than those who had fewer than two sexual partners. In conclusion, a high prevalence of multiple infections prior to the national HPV immunization program was observed, especially with the increase in less safe behavior factors.

Study protocol: epidemiological and clinical characteristics of acute viral hepatitis in Brazilian health services.

INTRODUCTION: Acute viral hepatitis is a disease of great clinical importance. This study proposes actions to better characterise cases of acute hepatitis in Brazil and to provide relevant information to institutionalised health policies within the Unified Health System. Available data on acute hepatitis in Brazil need to be re-evaluated regarding the different hepatotropic agent (hepatitis A to E virus) frequencies, as well as other agents that can cause similar clinical conditions, such as Herpes Simplex Virus 1 and 2(HSV1, HSV2), Varicella Zoster Virus (VZV), Cytomegalovirus (CMV), Epstein Barr Virus (EBV), Human Herpes Virus 6 and 7 (HHV6, HHV7), arbovirus (yellow fever, dengue, chikungunya, Zika), parvovirus B19, adenovirus, parechovirus, enterovirus, HIV, leptospirosis, toxoplasmosis and syphilis, in addition to autoimmune hepatitis. In this context, the primary aim of this study is the clinical-epidemiological and molecular characterisation of acute viral hepatitis in Brazilian health services from all geographical regions of the country. The present article describes the study protocol. METHODS AND ANALYSIS: This study will evaluate 2280 patients with symptoms and/or signs suggestive of acute liver disease in Brazilian health institutions in all five geographic Brazilian regions. Demographic, epidemiological and clinical data will be collected, as well as blood samples to be analysed at Hospital Israelita Albert Einstein Clinical Laboratory. ETHICS AND DISSEMINATION: Ethics approval was obtained at the national research ethics committee (Conselho Nacional de Ética em Pesquisa- CONEP-CAAE 00952818.4.1001.0071) and at all participating sites. Results will be published in journals and presented at scientific meetings.

Prevalence of oral HPV infection in unvaccinated young adults in Brazil.

OBJECTIVES: This study aimed to report the national prevalence of oral HPV infection among unvaccinated women and men aged 16-25 years who utilized the public primary care services. METHODS: POP-Brazil is a cross-sectional, multicentric, nationwide survey conducted between September 2016 and November 2017. Recruitment was based in 119 public primary care practices in 26 state capitals and the Federal District of Brazil. Trained health professionals conducted face-to-face interviews. Oral samples were collected with mouthwash and gargle cycles. Genotyping was performed using the Roche PCR-based linear array genotyping test. Sampling weights by sex and age were applied. RESULTS: Valid oral HPV samples were collected from 5071 (96.88%) participants; 4005 women and 1066 men. Mean participant age was 21.63 years. Overall HPV prevalence was 1.69% (n = 73, 95% CI 1.05-2.32). Thirty individuals presented at least one high-risk HPV type [0.57% (95% CI, 0.29-0.85)]. There were no associations between age, sex, sociodemographic characteristics, drug use or sexual behavior and oral HPV prevalence. CONCLUSION: The prevalence of oral HPV infection in Brazilian teenagers and young adults is low, with no sociodemographic or behavioral correlates.

Effectiveness of a universal vaccination program with an HPV quadrivalent vaccine in young Brazilian women.

We examined human papillomavirus (HPV) vaccine effectiveness in a nationwide sample of women aged 16 to 25 years who utilized the public health system in Brazil. This was a cross-sectional, multicentric survey conducted between September 2016 and November 2017 (POP-Brazil Study). A total of 5,945 young adult women were recruited from 119 public primary care units from all 27 federative units of Brazil by trained health professionals. The participants participated in a face-to-face interview and provided biological samples for genital HPV analysis. HPV genotyping was performed using a Linear Array HPV genotyping test in a central laboratory. Sampling weights were applied to the data. Overall, 11.92% (95% CI 10.65, 13.20) of the participants reported having been vaccinated. The frequency of vaccination was highest in 16- to 17-year-old women, with a decreasing vaccination rate with increasing age, and vaccinated women were more likely to belong to the high socioeconomic status group. The use of a quadrivalent vaccine decreased the HPV types 6, 11, 16, and 18 by 56.78%, from 15.64% in unvaccinated women to 6.76% in vaccinated women (P < 0.01), even after adjustment for age. Those who received the vaccine had lower HPV 16 (2.34% in vaccinated vs 8.91% in unvaccinated, P < 0.01) and 6 rates (2.06% vs 5.77%, P < 0.01). Additionally, a higher rate of high-risk HPV types other than HPV 16 and 18 (40.47% in vaccinated vs 32.63% in unvaccinated, P < 0.01) was observed. In conclusion, the results of this study support the effectiveness of HPV vaccination in Brazil. Continuous surveillance must be assured to monitor the HPV infection rate in the vaccination era.

Dolutegravir and pregnancy outcomes in women on antiretroviral therapy in Brazil: a retrospective national cohort study.

BACKGROUND: Dolutegravir has been widely available in Brazil since 2017. Following the signal that infants born to women with dolutegravir exposure at conception in Botswana had a higher risk of neural tube defects (NTDs), public health leaders initiated a national investigation to evaluate periconception dolutegravir exposure among all pregnant Brazilian women with HIV and its potential association with risk of NTDs, stillbirth, or miscarriage before 22 weeks (also called spontaneous abortion). METHODS: In this retrospective, observational, national, cohort study, we identified all women with pregnancies and possible dolutegravir exposure within 8 weeks of estimated date of conception between Jan 1, 2017, and May 31, 2018, and approximately 3:1 matched pregnant women exposed to efavirenz between Jan 1, 2015, and May 31, 2018, using the Brazilian antiretroviral therapy database. We did detailed chart reviews for identified women. The primary outcomes were NTD and a composite measure of NTD, stillbirth, or miscarriage. NTD incidences were calculated with 95% CI. The composite outcome was examined with logistic regression using propensity score matching weights to balance confounders. FINDINGS: Of 1427 included women, 382 were exposed to dolutegravir within 8 weeks of estimated date of conception. During pregnancy, 183 (48%) of 382 dolutegravir-exposed and 465 (44%) of 1045 efavirenz-exposed women received folic acid supplementation. There were 1452 birth outcomes. There were no NTDs in either dolutegravir-exposed (0, 95% CI 0-0·0010) or efavirenz-exposed groups (0, 95% CI 0-0·0036). There were 23 (6%) stillbirths or miscarriages in 384 dolutegravir-exposed fetuses and 28 (3%) in the 1068 efavirenz-exposed fetuses (p=0·0037). Logistic regression models did not consistently indicate an association between dolutegravir exposure and risk of stillbirths or miscarriages. After study closure, two confirmed NTD outcomes in fetuses with periconception dolutegravir exposure were reported to public health officials. An updated estimate of NTD incidence incorporating these cases and the estimated number of additional dolutegravir-exposed pregnancies between Jan 1, 2015 and Feb 28, 2019, is 0·0018 (95% CI 0·0005-0·0067). INTERPRETATION: Neither dolutegravir nor efavirenz exposure was associated with NTDs in our national cohort; incidence of NTDs is probably well under 1% in dolutegravir-exposed HIV-positive women but still slightly above HIV-uninfected women (0·06%) in Brazil. FUNDING: The Brazilian Ministry of Health and the United States' National Institutes of Health.

Sexual behavior and its association with persistent oral lesions: analysis of the POP-Brazil study.

OBJECTIVES: To investigate whether the presence of persistent self-reported oral lesions (PSOLs) is associated with sexual behaviors and with the presence of sexually transmitted infections (STIs) in individuals aged 16-25 years in the state capitals of Brazil. MATERIALS AND METHODS: Data from the POP-Brazil study were analyzed. An association analysis was performed by Poisson regression with the presence of PSOLs as the outcome. The exposure variables were the age at first sexual intercourse, the number of partners, oral sex practice, and aspects of condom use for model 1, and the presence of a self-reported STI or a positive rapid test for HIV/syphilis and the presence of genital human papillomavirus (HPV) for model 2. The results were adjusted for socioeconomic variables. RESULTS: The prevalence of PSOLs was 76% higher among individuals who had two or more sexual partners in the past year (p = 0.046) and 68% higher in those who reported not using condoms for contraception (p = 0.032). The group with HIV/syphilis or self-reported STI had a 140% higher PSOL prevalence (p = 0.003). CONCLUSIONS: The self-report of oral lesions in adolescents and young adults may suggest risky sexual behavior and the presence of STI. CLINICAL RELEVANCE: It is necessary to contextualize the reality of the young person to optimize oral health care.

Sífilis em jovens conscritos brasileiros, 2016: aspectos sociodemográficos, comportamentais e clínicos / Syphilis in young Brazilian military recruits in 2016: sociodemographic, behavioral, and clinical aspects / Sífilis en jóvenes reclutas brasileños, 2016: aspectos sociodemográficos, comportamentales y clínicos

O objetivo foi caracterizar aspectos sociodemográficos, comportamentais e clínicos entre conscritos brasileiros, segundo a prevalência de sífilis. Estudo descritivo desenvolvido valendo-se de pesquisa nacional de base populacional, realizada em 2016, com amostra probabilística de jovens conscritos de 17 a 22 anos de idade. Realizou-se autoaplicação de questionários confidenciais. As amostras de sangue total dos participantes foram coletadas para testagem de sífilis, com a utilização de testes treponêmicos e não treponêmicos. Empregaram-se técnicas de estatística descritiva para estimar as prevalências de sífilis e a distribuição de frequências entre as variáveis pesquisadas, considerando os intervalos de 95% de confiança (IC95%), após a ponderação dos dados. Do total de 37.282 participantes, 73,7% haviam iniciado a vida sexual. As prevalências de sífilis na vida e de sífilis confirmada foram de 1,6% e 1,1%, respectivamente. As seguintes variáveis populacionais apresentaram maior prevalência de sífilis: ausência de acesso à Internet no domicílio; início da atividade sexual antes dos 14 anos; categoria de exposição homens que fazem sexo com homens; práticas sexuais com mais de cinco parcerias; recebimento de presentes, drogas ou outros incentivos em troca de sexo; e história prévia de sintomatologia de infecções sexualmente transmissíveis. Observou-se o aumento de sífilis entre os jovens conscritos brasileiros, em comparação aos inquéritos anteriores. Tal incremento reforça a importância dessa população sentinela para realizar vigilância ativa, de forma a subsidiar estratégias de atenção à saúde dos jovens, incluindo cenários escolares.

The objective was to characterize sociodemographic, behavioral, and clinical aspects in young Brazilian military recruits according to prevalence of syphilis. This was a descriptive study based on a nationwide population-based survey in 2016 with a probabilistic sample of military recruits 17 to 22 years of age. A confidential self-applied questionnaire was used. Blood samples were drawn from participants for treponemal and non-treponemal syphilis tests. Descriptive statistical techniques were used to estimate syphilis prevalence rates and distribution of frequencies between the target variables, considering 95% confidence intervals (95%CI), after weighting the data. Of the total of 37,282 participants, 73.7% were sexually initiated. Prevalence rates for lifetime and confirmed syphilis were 1.6% and 1.1%, respectively. The following population variables showed higher prevalence of syphilis: lack of Internet access at home; initiation of sexual activity before 14 years of age; men who have sex with men; more than five sexual partners; having received presents, drugs, or other incentives in exchange for sex; and prior history of symptoms of sexually transmissible infections. An increase was observed in syphilis in Brazilian military recruits when compared to previous surveys. This increase emphasizes the importance of this sentinel population for performing active surveillance in order to support healthcare strategies for youth, including in the school system.
