RESUMO

BACKGROUND: HIV testing rates among South African men lag behind rates for women and national targets. Community-based HIV self-screening (HIVSS) distribution and follow-up by community health workers (CHWs) is a scalable option to increase testing coverage, diagnosis, and treatment initiation. We provided HIVSS and assisted linkage to care to men not recently tested (within the past 12 months) residing in high-HIV-burden areas of Johannesburg. METHODS: CHWs distributed HIVSS in 6 clinic catchment areas. Follow-up to encourage confirmatory testing and antiretroviral therapy initiation was conducted through personal support (PS) or an automated short message service (SMS) follow-up and linkage system in 3 clinic areas each. Using a quasi-experimental pre-post design, we compared differences in the proportion of men testing in the clinic catchment areas during the HIVSS campaign (June-August 2019) to the 3 months prior (March-May 2019) and compared treatment initiations by assisted linkage strategy. RESULTS: Among 4793 participants accepting HIVSS, 62% had never tested. Among 3993 participants with follow-up data, 90.6% reported using their HIVSS kit. Testing coverage among men increased by 156%, from under 4% when only clinic-based HIV testing services were available to 9.5% when HIVSS and HIV testing services were available (z = -11.6; P < 0.01). Reported test use was higher for men followed through PS (99% vs. 68% in SMS); however, significantly more men reported reactive self-test results in the SMS group compared with PS (6.4% vs. 2.0%), resulting in more antiretroviral therapy initiations in the SMS group compared with PS (23 vs. 9; P < 0.01). CONCLUSIONS: CHW HIVSS distribution significantly increases testing among men. While PS enabled personalized follow-up, reporting differences indicate SMS is more acceptable and better aligned with expectations of privacy associated with HIVSS.

RESUMO

BACKGROUND: Research trial participation may influence health outcomes regardless of the intervention assigned, but is often not assessed. SETTING: We investigated how participation in an HIV prevention trial (the HIV Prevention Trials Network (HPTN) 068 study) affected health outcomes 4 years after the study in adolescent girls and young women in South Africa beyond effects of the tested intervention. METHODS: We developed an analytical cohort that included the HIV Prevention 068 trial (HPTN 068) trial participants from the Agincourt Health and Demographic Surveillance System and resembled HPTN 068 trial enrollees (aged 13-20 years and in grades 8-11 in 2011) using inverse probability of treatment weights. We estimated risk differences for the association between trial participation and education and early parity (age <20 years) in 2019, after accounting for differences at baseline between the trial participants and nonparticipants. RESULTS: There were 3442 young women enrolled in grades 8-11 in 2011; 1669 were in the HPTN 068 trial. Trial participants were more likely to have completed secondary school by 2019 (adjusted RD (aRD) 5.0%, 95% confidence interval (CI) 2.2%, 7.9%; 82.3% in trial participants vs. 77.2% in nonparticipants). Trial participants had similar risk of parity before age 20 compared with nontrial participants (aRD 2.3%, 95% CI: -0.8%, 5.5%). CONCLUSIONS: Trial participation did not seem to influence early parity, but did increase educational attainment. Our results are compatible with an explanation of Hawthorne effects from trial participation on schooling behaviors that were small, but observable even 4 years after the end of the trial.

RESUMO

Travestis e mulheres trans (TrMT) pertencem aos grupos com mais alta prevalência do HIV no mundo, com maior probabilidade de infecção em relação à população geral e menor adesão a estratégias de prevenção e tratamento do que outros grupos vulneráveis. Considerando esses desafios, descrevemos os fatores associados à retenção de TrMT com HIV no projeto TransAmigas. O recrutamento ocorreu entre abril de 2018 e setembro de 2019, em um serviço público de saúde em São Paulo, Brasil. Foram inscritas 113 TrMT, atribuídas aleatoriamente para uma intervenção com navegadora de pares (75) ou um grupo controle (38) e seguidas durante nove meses. Para analisar a associação entre as variáveis selecionadas e o desfecho ("retenção aos nove meses" independentemente do contato aos três meses, definido pela "resposta completa ao questionário final"), foram empregados modelos de regressão logística bi e multivariados. Uma exploração qualitativa dos formulários de contato de pares foi realizada para validar e complementar a seleção prévia de variáveis do componente quantitativo. Das 113 participantes, 79 (69,9%) responderam à entrevista de nove meses, sendo 54 (72%) do grupo intervenção e 25 (66%) do grupo controle. No modelo multivariado final, o contato aos três meses (odds ratio ajustado - ORa = 6,15; intervalo de 95% de confiança - 95%CI: 2,16-17,51) e a maior escolaridade (≥ 12 anos) (ORa = 3,26; IC95%: 1,02-10,42) permaneceram associados ao desfecho, ajustados por raça/cor, idade < 35 anos e revelação do status sorológico para HIV. Pesquisas futuras com TrMT devem incluir contato em intervalos regulares, com esforços adicionais voltados a participantes com menor escolaridade.

Ante estos desafíos, describimos los factores asociados a la retención de TrMT con VIH en el proyecto TransAmigas. La selección ocurrió entre abril de 2018 y septiembre de 2019, en un servicio público de salud de São Paulo, Brasil. Se inscribieron 113 TrMT, a las cuales se asignaron aleatoriamente a una intervención de navegador de pares (75) o a un grupo control (38) y se les dio seguimiento durante 9 meses. Para analizar la asociación entre las variables seleccionadas y el resultado ("retención a los nueve meses" independientemente del contacto a los 3 meses, definido por "respuesta completa al cuestionario final"), se utilizaron modelos de regresión logística bi- y multivariante. Se realizó una exploración cualitativa de los formularios de contacto de pares para validar y complementar la selección previa de las variables en el componente cuantitativo.

En el modelo multivariante final, el contacto a los 3 meses (odds ratio ajustado - ORa = 6,15; intervalo de 95% de confianza - IC95%: 2,16-17,51) y un alto nivel de instrucción (≥ 12 años) (ORa = 3,26; IC95%: 1,02-10,42) permanecieron asociados con el resultado, ajustado por etnia/color, edad < 35 años y divulgación del estado serológico respecto al VIH. Los futuros estudios con la población TrMT deberán incluir contacto a intervalos regulares, con esfuerzos adicionales dirigidos a las participantes con menor nivel de instrucción.


Travestis and transgender women (TrTGW) constitute the groups with the highest HIV prevalence in the world, with higher probability of infection compared with the general population and lower adherence to prevention and treatment strategies than other vulnerable groups. Considering these challenges, this study describes the factors associated with the retention of TrTGW with HIV to the TransAmigas project. Participants were recruited from April 2018 to September 2019 in a public health service in São Paulo, Brazil. A total of 113 TrTGW were randomly assigned to either a peer navigation intervention (75) or a control group (38) and followed up for nine months. To analyze the association between the selected variables and the outcome ("retention at nine months", regardless of contact at three months, defined by the "full completion of the final questionnaire"), bivariate and multivariate logistic regression models were used. Peer contact forms were qualitatively assessed to validate and complement the previous selection of quantitative component variables. Of the 113 participants, 79 (69.9%) participated in the interview after nine months, of which 54 (72%) were from the intervention group and 25 (66%) from the control group. In the final multivariate model, contact at three months (adjusted odds ratio - aOR = 6.15; 95% confidence interval - 95%CI: 2.16-17.51) and higher schooling level (≥ 12 years) (aOR = 3.26; 95%CI: 1.02-10.42) remained associated with the outcome, adjusted by race/skin color, age ≤ 35 years, and HIV serostatus disclosure. Future studies with TrTGW should include contact at regular intervals, with additional efforts aimed at participants with lower schooling level.

RESUMO

BACKGROUND: Understanding factors driving virological failure, including the contribution of HIV drug resistance mutations (DRM), is critical to ensuring HIV treatment remains effective. We examine the contribution of drug resistance mutations for low viral suppression in HIV-positive participants in a population-based sero-prevalence survey in rural South Africa. METHODS: We conducted HIV drug resistance genotyping and ART analyte testing on dried blood spots (DBS) from HIV-positive adults participating in a 2014 survey in North West Province. Among those with virologic failure (> 5000 copies/mL), we describe frequency of DRM to protease inhibitors (PI), nucleoside reverse transcriptase inhibitors (NRTI), and non-nucleoside reverse transcriptase inhibitors (NNRTI), report association of resistance with antiretroviral therapy (ART) status, and assess resistance to first and second line therapy. Analyses are weighted to account for sampling design. RESULTS: Overall 170 DBS samples were assayed for viral load and ART analytes; 78.4% of men and 50.0% of women had evidence of virologic failure and were assessed for drug resistance, with successful sequencing of 76/107 samples. We found ≥1 DRM in 22% of participants; 47% were from samples with detectable analyte (efavirenz, nevirapine or lopinavir). Of those with DRM and detectable analyte, 60% showed high-level resistance and reduced predicted virologic response to ≥1 NRTI/NNRTI typically used in first and second-line regimens. CONCLUSIONS: DRM and predicted reduced susceptibility to first and second-line regimens were common among adults with ART exposure in a rural South African population-based sample. Results underscore the importance of ongoing virologic monitoring, regimen optimization and adherence counseling to optimize durable virologic suppression.

RESUMO

INTRODUCTION: To achieve epidemic control of HIV by 2030, countries aim to meet 90-90-90 targets to increase knowledge of HIV-positive status, initiation of antiretroviral therapy (ART) and viral suppression by 2020. We assessed the progress towards these targets from 2014 to 2016 in South Africa as expanded treatment policies were introduced using population-representative surveys. METHODS: Data were collected in January to March 2014 and August to November 2016 in Dr. Ruth Segomotsi Mompati District, North West Province. Each multi-stage cluster sample included 46 enumeration areas (EA), a target of 36 dwelling units (DU) per EA, and a single resident aged 18 to 49 per DU. Data collection included behavioural surveys, rapid HIV antibody testing and dried blood spot collection. We used weighted general linear regression to evaluate differences in the HIV care continuum over time. RESULTS: Overall, 1044 and 971 participants enrolled in 2014 and 2016 respectively with approximately 77% undergoing HIV testing. Despite increases in reported testing, known status among people living with HIV (PLHIV) remained similar at 68.7% (95% Confidence Interval (CI) = 60.9-75.6) in 2014 and 72.8% (95% CI = 63.6-80.4) in 2016. Men were consistently less likely than women to know their status. Among those with known status, PLHIV on ART increased significantly from 80.9% (95% CI = 71.9-87.4) to 91.5% (95% CI = 84.4-95.5). Viral suppression (<5000 copies/mL using DBS) among those on ART increased significantly from 55.0% (95% CI = 39.6-70.4) in 2014 to 81.4% (95% CI = 72.0-90.8) in 2016. Among all PLHIV an estimated 72.0% (95% CI = 63.8-80.1) of women and 45.8% (95% CI = 27.0-64.7) of men achieved viral suppression by 2016. CONCLUSIONS: Over a period during which fixed-dose combination was introduced, ART eligibility expanded, and efforts to streamline treatment were implemented, major improvements in the second and third 90-90-90 targets were achieved. Achieving the first 90 target will require targeted and improved testing models for men.

RESUMO

BACKGROUND: The uptake of HIV self-testing (HIVST) could address socio-structural barriers that prevent South African youth from utilizing the testing resources available in their communities. However, to facilitate this, we must tailor components of the HIVST kit and process to ensure that we reach and encourage youth to test. The purpose of this study to elucidate concerns and issues regarding HIVST rollout among South African youth. METHODS: This study was conducted in two phases: 1) focus group discussions with rural, South African youth aged 18-24 and 2) direct observations of participants completing with an oral HIVST kit and/or a blood based HIVST kit. In phase 2a participants were invited to try both an oral and blood-based HIVST kit. In phase 2b, participants selected the HIVST kit of their choice. RESULTS: We enrolled 35 unique participants in phase 1, 20 participants in phase 2a, and 40 participants in phase 2b. While the focus group discussions highlighted hypothetical HIVST use only, participants appreciated the privacy that the HIVST could afford them. However, they expressed concerns about whether HIVST could be trusted due to false positives and negatives, as well as whether a person would be able to emotionally handle the results if they tested alone. They suggested that the kits be used alongside someone who could provide support. In phases 2a and 2b, participants were overwhelmingly positive about both kits regarding ease of use and whether their results could be trusted. The participants, however, experienced more challenges with the blood-based versus oral test. When given the choice in phase 2b, most participants (80%) chose the oral HIVST over the blood-based HIVST. CONCLUSIONS: During the focus group discussions, participants raised concerns about the validity of HIVST, lack of emotional support when testing alone, and the cost of HIVST kits, all of which could be addressed through current testing campaigns. Most of those who actually tested had positive experiences with HIVST and would recommend it to their friends. When offered a choice, most preferred the oral test.

RESUMO

In Brazil, little data is available to inform HIV prevention programming for travestis and transgender ('trans') women, despite the existence of a social movement that has gained strength in recent years. We conducted formative research in Rio de Janeiro to gather trans women's perspectives on combination HIV prevention approaches. Framing the analysis within the model of gender affirmation, we found that several social and contextual factors inhibited participants' access to HIV prevention and treatment. Experienced and anticipated gender-related discrimination and HIV stigma were linked to the avoidance of HIV testing, health services and HIV status disclosure. Participants recommended HIV prevention interventions which combined socio-structural interventions, such as peer-based empowerment and social support, with biomedical interventions such as pre-exposure prophylaxis (PrEP). Participants expressed a preference for programmes and interventions that emphasised a gender-affirmative approach, promoted autonomy and aimed to reduce stigma and discrimination in public health services.

RESUMO

BACKGROUND: HIV self-testing (HIVST) may increase HIV testing uptake, facilitating earlier treatment for key populations like MSM who experience barriers accessing clinic-based HIV testing. HIVST usability among African MSM has not been explored. METHODS: We assessed usability of oral fluid (OF) and fingerstick (FS; blood) HIVST kits during three phases among MSM with differing degrees of HIVST familiarity in Mpumalanga, South Africa. In 2015, 24 HIVST-naïve MSM conducted counselor-observed OF and FS HIVST after brief demonstration. In 2016 and 2017, 45 and 64 MSM with experience using HIVST in a pilot study chose one HIVST to conduct with a counselor-observer present. In addition to written, the latter group had access to video instructions. We assessed frequency of user errors and reported test use ease, changes in error frequency by phase, and covariates associated with correct usage using log-Poisson and Gaussian generalized estimating equations. RESULTS: Among OF users (n = 57), 15-30% committed errors in each phase; however, observers consistently rated participants as able to test alone. Among FS users (n = 100), observers noted frequent errors, most commonly related to blood collection and delivery. We found suggestive evidence (not reaching statistical significance) that user errors decreased, with 37.5%, to 28.1%, and 18.2% committing errors in phases I, II, and III, respectively (p-value:0.08), however observer concerns remained constant. Ease and confidence using HIVST increased with HIV testing experience. Participants using three HIVST were more likely (RR:1.92, 95% CI:1.32, 2.80) to report ease compared to those without prior HIVST experience. Never testers (RR:0.66, 95% CI:0.44-0.99) reported less ease performing HIVST compared to participants testing in the past six months. CONCLUSIONS: MSM were able to perform the OF test. Fingerstick test performance was less consistent; however preference for fingerstick was strong and performance may improve with exposure and instructional resources. Continued efforts to provide accessible instructions are paramount.

RESUMO

INTRODUCTION: Adolescent girls and young women (AGYW) in South Africa bear a disproportionate burden of HIV. Community mobilization (CM), defined as community members taking collective action to achieve a common goal related to health, equity and rights, has been associated with increased HIV testing and condom use and has been called a 'critical enabler' for addressing the HIV epidemic. However, limited research has examined whether CM is associated with HIV incidence among AGYW. METHODS: We examine the association of CM with incident HIV among AGYW (ages 13 to 21) enrolled in the HPTN 068 cohort in the Agincourt Health and socio-Demographic Surveillance System, South Africa. This analysis includes 2292 participants residing in 26 villages where cross-sectional, population-based surveys were conducted to measure CM among 18- to 35-year-old residents in 2012 and 2014. HPTN 068 participants completed up to five annual visits that included an HIV test (2011 to 2016). Household-level data were collected from AGYW parents/guardians and census data is updated annually. Mean village-level CM scores were created using a validated community mobilization measure with seven components (social cohesion, social control, critical consciousness, shared concerns, organizations and networks, leadership and collective action). We used pooled generalized estimating equation regression with a Poisson distribution to estimate risk ratios (RR) for the association of village-level CM score and CM components with incident HIV infection, accounting for village-level clustering and adjusting for key covariates. RESULTS: There were 194 incident infections over the follow-up period. For every additional standard deviation of village-level CM there was 12% lower HIV incidence (RR: 0.88, 95% CI: 0.79, 0.98) after adjusting for individual, household and community characteristics. CM components associated with lower HIV incidence included critical consciousness (RR: 0.88; CI: 0.79, 0.97) and leadership (RR: 0.87; CI: 0.79, 0.95); while not statistically significant, social cohesion (RR: 0.91; CI: 0.81, 1.01), shared concerns (RR: 0.90; CI: 0.81, 1.00), and organizations and networks (RR: 0.91; CI: 0.79, 1.03) may also play a protective role. CONCLUSIONS: These results suggest that having strong community social resources will reduce AGYW's risk of HIV acquisition. Work to mobilize communities, focusing on building social cohesion, shared concerns, critical consciousness, and effective and accountable leadership, can fortify prevention programming for AGYW.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) self-testing (HIVST) provides a promising tool to screen sex partners for men who have sex with men (MSM) who engage in condomless sex and want to avoid HIV infection. Although previous studies have demonstrated HIVST acceptability and increased testing uptake, limited data exist on its use between sex partners for point-of-sex HIV testing. This study examined prevalence and correlates of point-of-sex HIVST among Chinese MSM. METHODS: A cross-sectional survey was conducted among 400 HIV-negative Chinese MSM in 2017. Participants were recruited through a multifaceted sampling approach and self-administered an electronic questionnaire. Point-of-sex HIVST was measured by asking participants if they had ever conducted HIVST with a sex partner before sex to ensure that they both knew their HIV statuses. Multivariable logistic regression was used to identify correlates of point-of-sex HIVST after controlling for age, education and sexual orientation. RESULTS: Overall, 19.2% (77/400) men reported point-of-sex HIVST (51.3% among self-testers). Participants who had four or more HIV self-tests before had 7.57-fold greater odds (95% confidence interval, 3.75, 15.28) of reporting point-of-sex HIVST compared to those who had fewer HIVST experiences. Point-of-sex HIVST was otherwise not associated with most other socio-demographic or behavioral practices, suggesting that it may be broadly acceptable. CONCLUSIONS: A substantial proportion of Chinese MSM had utilized HIVST with their partners before sex, especially among those who were more experienced with HIVST. Scale up and routine implementation of HIVST programs are further warranted to facilitate point-of-sex HIV testing.

RESUMO

BACKGROUND: South African men who have sex with men (MSM) have a high burden of undiagnosed HIV infection and HIV-testing rates incommensurate with their risk. HIV self-testing (HIVST) may increase testing uptake, frequency, and earlier HIV detection and treatment. SETTING: Gert Sibande and Ehlanzeni districts, Mpumalanga Province, South Africa. METHODS: We conducted a longitudinal HIVST study among MSM between June 2015 and May 2017. Overall 127 HIV-negative MSM were provided with up to 9 test kits of their choice-oral fluid or blood fingerstick-to use themselves and distribute to their networks. Surveys conducted 3- and 6-month post-enrollment elicited information on HIVST experiences, preferences, acceptability, utilization, and distribution. We used generalized estimating equations to assess changes in testing frequency. RESULTS: Ninety-one percent of participants self-tested. All participants who self-tested reported being likely to self-test again, with over 80% preferring HIVST to clinic-based testing. Fingerstick was preferred to oral fluid tests by approximately 2:1. Returning participants distributed 728 tests to sexual partners (18.5% of kits), friends (51.6%), and family (29.8%). Six participants seroconverted during the study, and 40 new diagnoses were reported among test recipients. Frequent (semi-annual) testing increased from 37.8% before the study to 84.5% at follow-up (P < 0.001), and participants reported anticipated frequent testing of 100% if HIVST were available compared with 84% if only clinic-testing were available in the coming year (P < 0.01). CONCLUSIONS: HIVST use and network distribution is acceptable and feasible for MSM in South Africa and can increase testing uptake and frequency, potentially improving early detection among MSM and their networks.

RESUMO

Stigma remains a significant barrier to HIV testing in South Africa. Despite being a social construct, most HIV-stigma research focuses on individuals; further the intersection of gender, testing and stigma is yet to be fully explored. We examined the relationship between anticipated stigma at individual and community levels and recent testing using a population-based sample (n = 1126) in Mpumalanga, South Africa. We used multi-level regression to estimate the potential effect of reducing community-level stigma on testing uptake using the g-computation algorithm. Men tested less frequently (OR 0.22, 95% CI 0.14-0.33) and reported more anticipated stigma (OR 5.1, 95% CI 2.6-10.1) than women. For men only, testing was higher among those reporting no stigma versus some (OR 1.40, 95% CI 0.97-2.03; p = 0.07). For women only, each percentage point reduction in community-level stigma, the likelihood of testing increased by 3% (p < 0.01). Programming should consider stigma reduction in the context of social norms and gender to tailor activities appropriately.

RESUMO

We distributed free OraQuick In-home HIV Test® kits to men at a gay bathhouse. Men were systematically selected to receive a coupon, which could be redeemed that night for an HIV self-testing kit. Those offered the coupon were asked to take an 11-item survey. About 181 men received coupons, of whom 92 (51%) accepted the coupon, and 61 (66%) men redeemed the coupon. Those who redeemed test kits and completed a survey (n = 53) were more ethnically diverse (χ(2) = 100.69, p < .01) than those receiving the coupon. More than half had not tested in the past 6 months (50%) or never tested (7%). Importantly, men who had never tested or who last tested more than 6 months ago were among those most likely to take the free test kit. We found bathhouse distribution could reach a population of men who have sex with men most in need of improved access to HIV testing. Future studies should consider means of improved follow-up and linkage to care for those who test positive.

RESUMO

An estimated one in four transgender women (trans women) in the U.S. are infected with HIV. Rates of HIV testing are not commensurate with their risk, necessitating alternative strategies for early detection and care. We explored the feasibility and acceptability of HIV self-testing (HIVST) with 50 HIV-negative adult trans women in San Francisco. Participants received three self-test kits to perform once a month. Acceptability and behavioral surveys were collected as were 11 in-depth interviews (IDIs). Among 50 participants, 44 reported utilizing HIVST at least once; 94 % reported the test easy to use; 93 % said results were easy to read; and 91 % would recommend it to others. Most participants (68 %) preferred HIVST to clinic-based testing, although price was a key barrier to uptake. IDIs revealed a tension between desires for privacy versus support found at testing sites. HIVST for trans women was acceptable and feasible and requires careful consideration of linkage to support services.

RESUMO

Increasing access and frequency of human immunodeficiency virus testing are critical to stemming the epidemic. In Brazil's concentrated epidemic, human immunodeficiency virus prevalence in the men who have sex with men/transgender population far exceeds that in the general population, but testing rates fall below what is needed to ensure early detection and treatment. Over-the-counter human immunodeficiency virus self-testing kits, now available in stores in the U.S., have enormous potential to increase testing access and frequency and to facilitate early detection and treatment. With the advent of human immunodeficiency virus self-testing upon us, it is timely to engage the scientific community, government, and civil society in a dialog around how to best utilize this technology in Brazil. We summarize recent research on over-the-counter testing among men who have sex with men, raise potential questions and challenges to using self-tests, suggest implementation strategies, and outline a research agenda moving forward.

RESUMO

The Brazilian HIV/AIDS epidemic is concentrated among men who have sex with men (MSM), however HIV testing rates among MSM are not commensurate with their risk. Strategies to expand early diagnosis may include use of self-conducted home-based testing kits, which are now available for purchase in the US. In April 2011 we conducted a survey with Brazilian MSM using Facebook to assess HIV testing preferences and acceptability of home-based testing. Among 356 previously tested, HIV-negative MSM, 47% reported a preference for home-based testing, 27% preferred clinic-based testing, and 26% had no preference. Less frequent testers and those who had considered testing but failed to test were more likely to prefer home-based testing. Close to 90% reported that they would use self-test kits; 62% and 54% said they would use home-based testing to make choices about unprotected sex with regular and new partners, respectively. Concerns included difficulty to understand the tests (32%) and receiving results alone (23%). Overall, home-based testing may appeal to MSM and result in increased testing frequency. Research on feasibility and utilization of self-tests in practice is needed.


A epidemia de HIV/AIDS no Brasil é concentrada em homens que fazem sexo com homens (HSH), mas suas taxas de testagem são incompatíveis com seus riscos. Estratégias para expandir o diagnóstico precoce entre HSH podem incluir kits de autotestagem em ambiente doméstico (AAD), como os disponíveis para compra nos Estados Unidos. Em abril de 2011, realizamos uma pesquisa com HSH brasileiros recrutados em Facebook para conhecer preferências de testagem e aceitabilidade da AAD. Entre 356 HSH HIV(-) testados previamente, 47% preferiam a AAD, 27% testagem em clínicas e 26% sem preferência. HSH com menos testagem ou que consideraram a testagem sem fazê-la tinham maior probabilidade de preferir a AAD (p < 0,05). Quase 90% usariam a AAD, 62 e 54% para decidir sobre ter sexo desprotegido com parceiros regulares e novos, respectivamente. Dificuldade de entender os testes (32%) e receber os resultados sozinhos (23%) foram preocupações referidas. Testes anti-HIV de AAD podem ser atrativos para HSH e resultar em aumento de testagem. Pesquisas com foco na viabilidade e utilização dos kits AAD na prática são necessárias.


La epidemia de VIH/SIDA en Brasil se concentra en hombres que practican sexo con hombres (HSH), pero los índices de exámenes clínicos para conocer si están infectados son incompatibles con sus riesgos. Las estrategias para expandir el diagnóstico precoz entre HSH pueden incluir kits de autoanálisis para el hogar, como los que están a disposición del público en Estados Unidos. En abril de 2011, realizamos una investigación con HSH brasileños, captados en Facebook, para conocer preferencias de exámenes y la aceptabilidad del autoanálisis en un ambiente doméstico. Entre los 356 HSH VIH(-) analizados previamente, un 47% preferían un autoanálisis en un ambiente doméstico, un 27% pruebas en clínicas y un 26% no tenían preferencias. HSH que menos exámenes se realizaron o quienes los consideraron, pero no se los hicieron, tenían mayor probabilidad de preferir el autoanálisis en un ambiente doméstico. Casi un 90% usarían autoanálisis en su hogar, un 62% y 54% con el fin de decidir sobre tener sexo sin protección con parejas regulares y nuevas, respectivamente. La dificultad de entender los análisis (32%) y recibir los resultados a solas (23%) fueron las preocupaciones a las que se refirieron. Los análisis anti-VIH de autoadministración en el hogar pueden ser atractivos para HSH y resultar en un aumento de exámenes. Las investigaciones centradas en la viabilidad y utilización de los test de autoanálisis en la práctica son necesarias.

RESUMO

INTRODUÇÃO: Infecções Sexualmente Transmissíveis (IST) em mulheres permanecem um desafio para a Saúde Pública: elevada prevalência, dificuldade para implantação de estratégias de diagnóstico precoce e elevada ocorrência de sequelas. OBJETIVO: Identificar a prevalência de IST em usuárias de um serviço de atenção primária à saúde em São Paulo. MÉTODOS: Mulheres de 18 a 40 anos foram convidadas para realizar autocoleta de secreção vaginal para a detecção de Chlamydia trachomatis, Neisseria gonorrhoeae e Trichomonas vaginalis por meio de Reacão em Cadeia da Polimerase (PCR). As mulheres também responderam a um questionário com questões demográficas e relativas à história sexual face a face ou autoaplicado por meio de um computador. RESULTADOS: Das 781 mulheres incluídas no estudo, as prevalências obtidas foram: Chlamydia trachomatis (8,4 por cento), Neisseria gonorrhoeae (1,9 por cento) e Trichomonas vaginalis (3,2 por cento). A positividade para pelo menos uma das três IST foi de 13 por cento. As variáveis associadas independentemente com maior risco de IST foram: idade menor que 20 anos, mais de dois parceiros sexuais na vida e percepção de risco para IST; o uso de preservativo como método contraceptivo foi um fator protetor. CONCLUSÃO: A prevalência encontrada em usuárias indica a necessidade da implantação de estratégias de rastreamento de IST em serviços de atenção primária.


INTRODUCTION: Sexually Transmitted Infections (STIs) in women remain a public health challenge due to high prevalence, difficulties to implement early diagnosis strategies and high rates of complications. OBJECTIVE: Identify the prevalence of STIs among users of a primary health care clinic in São Paulo. METHODS: Women, 18 to 40 years of age, were invited to self-collect vaginal specimens to be tested for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis by Polymerase Chain Reaction (PCR). Women were also invited to answer a demographic and sexual history questionnaire, either on the computer or face-to-face. RESULTS: The prevalence of STIs obtained from the 781 women included in the study was: Chlamydia trachomatis: 8.4 percent, Neisseria gonorrhoeae: 1.9 percent, and Trichomonas vaginalis: 3.2 percent. Thirteen percent tested positive for at least one out of the three STIs. The variables associated independently with a higher risk of STIs were: age under 20-years-old, more than two lifetime sexual partners, and self-perception of STI risk. The use of condoms as a contraceptive method proved to be a protective factor. CONCLUSION: The high prevalence found among these women indicates the need for the implementation of STI screening strategies in primary care settings in Brazil.

RESUMO

OBJECTIVE: The objective of this study was to determine whether home-based screening for sexually transmitted infections (STIs) is acceptable, feasible, and increases the proportion of women screened among low-income women in São Paulo, Brazil. STUDY DESIGN: Eight hundred eighteen women were randomized to receive a clinic appointment or a kit for home-based STI self-collection and testing. All participants collected 2 vaginal swabs, one for polymerase chain reaction detection of chlamydia, gonorrhea, and trichomoniasis and another for a self-conducted rapid test for trichomoniasis. RESULTS: Slightly more women responded to the initiative within 2 weeks in the home group (80%) than in the clinic group (76%) with younger women showing improved response to home-based screening. Ninety-four percent of home group participants successfully completed self-collection and self-testing on their first attempt. CONCLUSIONS: Home-based self-collection and self-testing was acceptable, feasible, and resulted in a slightly higher response rate. Home sampling and testing provide promising alternatives to clinic-based STI screening across diverse contexts.

RESUMO

OBJECTIVE: To determine the association between dyspareunia, dysmenorrhea, and noncyclic pelvic pain and the presence and characteristics of uterine fibroids. DESIGN: Population-based cross-sectional study. SETTING: Desio, Italy. PATIENT(S): Six hundred thirty-five non-care-seeking participants of the Seveso Women's Health Study with an intact uterus who underwent transvaginal ultrasound. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Ultrasound-detected presence of uterine fibroids and fibroid characteristics including volume, number, location, and position. Current dyspareunia, dysmenorrhea, and noncyclic pelvic pain was measured by self-report on a visual analog scale. RESULT(S): Uterine fibroids were detected in 96 women (15%). Women with fibroids were more likely to report moderate or severe dyspareunia (adjusted odds ratio [OR] = 2.8, 95% confidence interval [CI] = 0.9-8.3, statistically significant trend) and moderate or severe noncyclic pelvic pain (adjusted OR = 2.6, 95% CI = 0.9-7.6, statistically significant trend) than women without fibroids. Moderate or severe dysmenorrhea was not associated with the presence of fibroids (adjusted OR = 1.1, 95% CI = 0.5-2.6). Number and total volume of fibroids were not related to pain. CONCLUSION(S): This is the first population-based study of gynecologic pain symptoms and fibroids. Dyspareunia and noncyclic pelvic pain, but not dysmenorrhea, increased in severity with the presence of uterine fibroids. Fibroid-associated pain symptomatology in a non-care-seeking population may be different from that of a clinic population.
