Violence, Discrimination, and High Levels of Symptoms of Depression Among Adolescent Men Who Have Sex With Men and Transgender Women in Brazil.

PURPOSE: This study aimed at describing the prevalence of symptoms of depression among 15-19 year old adolescent men who have sex with men (aMSM) and transgender women (aTGW), who were recruited in an HIV pre-exposure prophylaxis cohort study in three Brazilian capital cities. The study also examined potential associations, including violence and discrimination, with severe symptoms of depression among aMSM. METHODS: This is a cross-sectional study of baseline data among 730 aMSM and 56 aTGW recruited between February 2019 and February 2021. Sociodemographic and behavioral data were collected. The 20-item Center for Epidemiologic Studies Depression scale was used to screen for symptoms of depression. Scores of ≥22 points indicate the presence of severe symptoms associated with major depression. Logistic regression was used to assess independent associations among aMSM, adjusting for sociodemographic variables. RESULTS: Our findings indicate a high prevalence of symptoms of depression (overall prevalence = 58.5% and 69.6%; 21.2% and 25.0% for mild/moderate, and 37.3% and 44.6% for severe) among these aMSM and aTGW, respectively. Psychological violence (aOR = 1.74; 95% CI = 1.12-2.70), sexual violence (aOR = 1.79; 95% CI = 1.07-2.98), and discrimination due to sexual orientation (aOR = 1.71; 95% CI = 1.23-2.38) were independently associated with severe symptoms of depression in aMSM. DISCUSSION: The high prevalence of severe symptoms of depression and its association with psychological and sexual violence and discrimination creates cycles of vulnerability and carries important public health implications. Thus, our findings indicate public policies should consider assessing depression, psychological and sexual violence, as well as discrimination, especially in populations that will be targeted by interventions, such as the use of pre-exposure prophylaxis.

Adherence, Safety, and Feasibility of HIV Pre-Exposure Prophylaxis Among Adolescent Men Who Have Sex With Men and Transgender Women in Brazil (PrEP1519 Study).

PURPOSE: To evaluate the adherence, safety, and feasibility of pre-exposure prophylaxis (PrEP) in real-world settings among adolescent men who have sex with men (AMSM) and transgender women (ATGW). METHODS: PrEP1519 is a single-arm, multicentric demonstration cohort study of daily oral PrEP among AMSM and ATGW aged 15 to 19 years in Brazil. Study visits occurred at baseline, weeks 4, 12, and then quarterly until 96 weeks. Descriptive statistics and a mixed logistic model for longitudinal data evaluated the factors associated with high adherence. RESULTS: One thousand sixteen AMSM and ATGW accessed the PrEP1519 clinics. Of those, 998 (98.2%) underwent clinical triage. Forty one were diagnosed with human immunodeficiency viruses (HIV) at baseline (4.0%) and 79 (7.9%) were not eligible for PrEP. Of the 878, 795 (90.5%) enrolled in PrEP, 82 (10.3%) were lost to follow-up, and 713 were included. There was no significant decrease in creatinine clearance; only two participants had grade-III aspartate aminotransferase elevation. Incident HIV infection occurred in eight participants (incidence rate [IR] = 1.64 per 100 person-years [PY]): two in 15-17 years (IR = 2.24 per 100 PY) and six in 18-20 years (IR = 1.51 per 100 PY). PrEP adherence was higher among those with more years of schooling, those reporting no difficulties in PrEP use due to side effects, and who had low HIV risk perception in the past three months. DISCUSSION: PrEP for AMSM and ATGW was safe and feasible in real-world settings. However, a higher IR among young adolescents and a higher adherence among less vulnerable people indicate the need for greater care, considering the specificities of this age group.

Longitudinal study of humoral immunity against SARS-CoV-2 of health professionals in Brazil: the impact of booster dose and reinfection on antibody dynamics.

Introduction: The pandemic caused by SARS-CoV-2 has had a major impact on health systems. Vaccines have been shown to be effective in improving the clinical outcome of COVID-19, but they are not able to fully prevent infection and reinfection, especially that caused by new variants. Methods: Here, we tracked for 450 days the humoral immune response and reinfection in 52 healthcare workers from Brazil. Infection and reinfection were confirmed by RT-qPCR, while IgM and IgG antibody levels were monitored by rapid test. Results: Of the 52 participants, 19 (36%) got reinfected during the follow-up period, all presenting mild symptoms. For all participants, IgM levels dropped sharply, with over 47% of them becoming seronegative by the 60th day. For IgG, 90% of the participants became seropositive within the first 30 days of follow-up. IgG antibodies also dropped after this period reaching the lowest level on day 270 (68.5 ± 72.3, p<0.0001). Booster dose and reinfection increased the levels of both antibodies, with the interaction between them resulting in an increase in IgG levels of 130.3 arbitrary units. Conclusions: Overall, our data indicate that acquired humoral immunity declines over time and suggests that IgM and IgG antibody levels are not associated with the prevention of reinfection.

Comparison of diagnostic performance of RT-qPCR, RT-LAMP and IgM/IgG rapid tests for detection of SARS-CoV-2 among healthcare workers in Brazil.

BACKGROUND: COVID-19 has become a major public health problem after the outbreak caused by SARS-CoV-2 virus. Great efforts to contain COVID-19 transmission have been applied worldwide. In this context, accurate and fast diagnosis is essential. METHODS: In this prospective study, we evaluated the clinical performance of three different RNA-based molecular tests - RT-qPCR (Charité protocol), RT-qPCR (CDC (USA) protocol) and RT-LAMP - and one rapid test for detecting anti-SARS-CoV-2 IgM and IgG antibodies. RESULTS: Our results demonstrate that RT-qPCR using the CDC (USA) protocol is the most accurate diagnostic test among those evaluated, while oro-nasopharyngeal swabs are the most appropriate biological sample. RT-LAMP was the RNA-based molecular test with lowest sensitivity while the serological test presented the lowest sensitivity among all evaluated tests, indicating that the latter test is not a good predictor of disease in the first days after symptoms onset. Additionally, we observed higher viral load in individuals who reported more than 3 symptoms at the baseline. Nevertheless, viral load had not impacted the probability of testing positive for SARS-CoV-2. CONCLUSION: Our data indicates that RT-qPCR using the CDC (USA) protocol in oro-nasopharyngeal swabs samples should be the method of choice to diagnosis COVID-19.

When prevention is the best remedy: HIV pre-exposure prophylaxis (PrEP) among adolescents gays and transgender women in Belo Horizonte, Minas Gerais State, Brazil.

Based on the incorporation of pre-exposure prophylaxis (PrEP) as an HIV prevention strategy and considering the need to comprehend the use of medication among young people, this article analyzes narratives of gay men and transgender women from Belo Horizonte, Minas Gerais State, Brazil, participating in the PrEP1519 study. This is a qualitative research, based on the interpretative anthropology, developed by 10 in-depth interviews with PrEP users followed-up for at least three months between October and November 2019. The results showed that the drug was seen as the main motivation for participating in the study and as a strategy combined with the use of condoms, whether as additional prevention, or assuming the leading role. The medication revealed signs built by the gender performances and their relation to other medications, especially the experience of trans girls in hormonal therapy. Regarding the socialization of the use of PrEP, the narratives showed that there was no secret between the couples, which did not meant that stigmas on the association with HIV did not exist, mainly in the virtual context. In the family environment, they reported questions about the preventive function of the medication and the voluntary nature of the participation in the study. The youth's narratives revealed plural meanings of the medication and its social use, composing both the boys' and girls' performances. The signs attributed to the medication indicated that in addition to maintenance of health, the medication improves life and sexual freedom.

Prevalence of syphilis and sexual behavior and practices among adolescents MSM and TrTGW in a Brazilian multi-center cohort for daily use of PrEP.

Syphilis has reemerged as a serious public health problem in Brazil and worldwide, disproportionately affecting men who have sex with men (MSM) and travestis and transgender women (TrTGW). Studies on sexually transmitted infections (STI) in adolescents from these key populations are relatively scarce. This is a Brazilian multi-center, cross study with prevalence analysis, using as baseline the PrEP1519 cohort of sexually active MSM and TrTGW adolescents, recruited from April 2019 to December 2020. Analyses were made using the dimensions of vulnerability to STI/HIV and logistic regression models were conducted to estimate the odds ratios of the association between the predictor variables and positive treponemal test for syphilis at the moment of entry in the study. In total, 677 participants were analyzed; participants' median age was 18.9 years (IQR: 18.1-19.5); 70.5% (477) self-declared as black; 70.5% (474), as homosexuals/gays; and 48 (7.1%), as trans women or travestis. The baseline prevalence of syphilis was 21.3%. In the final logistic regression model, higher chance of syphilis was associated with: self-reported episode of STI in the last 12 months (OR = 5.92; 95%CI: 3.74-9.37), sex worker (OR = 3.39; 95%CI: 1.32-8.78), and < 11 years of schooling (OR = 1.76; 95%CI: 1.13-2.74). The prevalence of syphilis among MSM/TrTGW adolescents aged from 15 to 19 years was alarming, much higher than the described for the general population within this age range and associated with vulnerability factors. This reinforces the urgent need to strengthen public health programs to debate about race, gender, sexuality, and prevention.

Factors associated to HIV prevalence among adolescent men who have sex with men in Salvador, Bahia State, Brazil: baseline data from the PrEP1519 cohort.

Adolescent men who have sex with men (AMSM) are at a heightened vulnerability for human immunodeficiency virus (HIV). This study aimed to estimate the prevalence of HIV and associated individual, social, and programmatic factors among AMSM in Salvador, Bahia State, Brazil. This is a cross-sectional study which analyzed baseline data from the PrEP1519 cohort in Salvador. Descriptive, bivariate, and multivariate analyses were conducted using the dimensions of vulnerability to HIV as hierarchical levels of analysis. Logistic regression models were used to estimate the odds ratios (OR) of the association between predictor variables and HIV infection. The prevalence of HIV infection among the 288 AMSM recruited to the project was 5.9% (95%CI: 3.7-9.3). Adjusted analysis showed a statistically significant association between self-identifying as a sex worker (OR = 3.74, 95%CI: 1.03-13.60) and HIV infection. Other associations with borderline statistical significance were the use of application programs to find sexual partners (OR = 3.30, 95%CI: 0.98-11.04), low schooling level (OR = 3.59, 95%CI: 0.96-13.41), failing to be hired or being dismissed from a job because of sexual orientation (OR = 2.88, 95%CI: 0.89-9.28), and not using health services as a usual source of care (OR = 3.14, 95%CI: 0.97-10.17). We found a high HIV prevalence among AMSM in Salvador. Furthermore, our study found that individual, social, and programmatic factors were associated with HIV infection among these AMSM. We recommend intensifying HIV combined-prevention activities for AMSM.

Interdisciplinarity in HIV prevention research: the experience of the PrEP1519 study protocol among adolescent MSM and TGW in Brazil.

At the end of 2017, Brazil adopted HIV pre-exposure prophylaxis (PrEP) as part of a combination prevention strategy for the most at-risk populations. However, Brazil does not have specific guidelines for PrEP use among adolescents aged < 18 years. Therefore, researchers from different health disciplines conducted PrEP1519, the first PrEP demonstration cohort study, ongoing in three Brazilian cities - Salvador, Belo Horizonte, and São Paulo - among adolescent men who have sex with men and transgender women, aged 15-19 years. This study aims to evaluate the effectiveness of PrEP in real-world settings. Quantitative and qualitative methods were integrated to obtain data on PrEP acceptability, uptake, use, and adherence. Moreover, comprehensive services and friendly environments were implemented in the PrEP1519 clinics. This study aims to describe the collaborative efforts of interdisciplinary practices in the development of the PrEP1519 study. The articulation of researchers from different institutions and areas is challenging; but it also allows for a broader outlook on questions regarding the direction of the research, while enriching the decisions needed to be taken during the interactions and negotiations among the different individuals, including the youth team and participants. Furthermore, it reflects on the communication process between cultures and languages considering the trans-epistemic arena of knowledge production about HIV, sexually transmitted infections, PrEP, and other combination prevention strategies for adolescents.

A sífilis reemergiu enquanto problema sério de saúde pública no Brasil e no mundo, afetando de maneira desproporcional homens que fazem sexo com homens (HSH), travestis e mulheres transgênero. São relativamente escassos os estudos sobre infecções sexualmente transmissíveis (IST) entre adolescentes pertencentes a essas populações-chave. O estudo transversal multicêntrico brasileiro analisou a prevalência de sífilis na linha de base da coorte PrEP15-19 de HSH, travestis e mulheres transgênero adolescentes, sexualmente ativos, recrutados entre abril de 2019 e dezembro de 2020. As análises foram realizadas com as dimensões de vulnerabilidade a ISTs/HIV, e modelos de regressão logística foram construídos para estimar as razões de chances da associação entre as variáveis preditoras e um teste treponêmico positivo para sífilis na entrada do estudo. Foram analisados 677 participantes. A idade mediana era 18,9 anos (IIQ: 18,1-19,5), 70,5% (477) se autoidentificaram como pretos, 70,5% (474) como homossexuais/gays e 48 (7,1%) como mulheres trans ou travestis. A prevalência de sífilis na linha de base era 21,3%. No modelo final de regressão logística, as seguintes variáveis estiveram associadas com chances maiores de sífilis: autorrelato de episódio de IST nos últimos 12 meses (OR = 5,92; IC95%: 3,74-9,37), profissional do sexo (OR = 3,39; IC95%: 1,32-8,78) e menos de 11 anos de escolaridade (OR = 1,76; IC95%: 1,13-2,74). A prevalência de sífilis entre HSH, travestis e mulheres transgênero adolescentes entre 15 e 19 anos de idade foi alarmante, muito acima da taxa relatada na população geral nesta faixa etária, e esteve associada a fatores de vulnerabilidade. Os achados reforçam a necessidade urgente de fortalecer os programas de saúde pública com a discussão sobre raça, gênero, sexualidade e prevenção.

La sífilis ha resurgido como un problema serio de salud pública en Brasil y en todo el mundo, afectando desproporcionadamente a hombres que tienen sexo con hombres (HSH), travestis y mujeres transgénero (TrTGW). Los estudios de las enfermedades trasmitidas sexualmente (ETS) en adolescentes de estas poblaciones clase son relativamente escasos. Se trata de un estudio transversal brasileño multicéntrico, con análisis de prevalencia de la base de referencia de la cohorte PrEP1519 de hombres activos sexualmente que mantienen sexo con hombres y adolescentes TrTGW, reclutados desde abril de 2019 a diciembre de 2020. Se hicieron análisis, usando las dimensiones de vulnerabilidad a las ETS/VIH, y se realizaron modelos de regresión logística para estimar las odds ratios de la asociación entre las variables predictoras y la prueba treponémica positiva para la sífilis al comenzar el estudio. Se analizaron a 677 participantes. La media de edad fue 18,9 años (IQR: 18,1-19,5), 70,5% (477) se autodeclararon como negros, 70,5% (474) como homosexuales/gays y 48 (7,1%) como mujeres trans o travestis. La base de referencia de prevalencia de sífilis fue 21,3%. En el modelo final de regresión logística, se asociaron con una posibilidad más alta de sífilis: un episodio autoinformado de ETS en los últimos 12 meses (OR = 5,92; IC95%: 3,74-9,37), trabajadores sexuales (OR = 3,39; IC95%: 1,32-8,78) y < 11 años de estudio (OR = 1,76; IC95%: 1,13-2,74). La prevalencia de sífilis entre adolescentes HSH/TrTGW con edades de 15 a 19 años fue alarmante, mucho más que lo descrito para la población general en este rango de edad y asociado con factores de vulnerabilidad. Esto refuerza la urgente necesidad de fortalecer los programas de salud pública, discutiendo cuestiones de raza, género, sexualidad y prevención.

Factors associated to HIV prevalence among adolescent men who have sex with men in Salvador, Bahia State, Brazil: baseline data from the PrEP1519 cohort / Fatores associados à prevalência do HIV entre homens adolescentes que fazem sexo com homens em Salvador, Bahia, Brasil: dados da linha de base da coorte PrEP1519 / Factores asociados a la prevalencia de VIH entre hombres adolescentes que tienen sexo con hombres en Salvador, Bahia, Brasil: datos de referencia de la cohorte PrEP1519

We found a high HIV prevalence among AMSM in Salvador. Furthermore, our study found that individual, social, and programmatic factors were associated with HIV infection among these AMSM. We recommend intensifying HIV combined-prevention activities for AMSM.

Homens adolescentes que fazem sexo com homens (AHSH) apresentam vulnerabilidade aumentada ao HIV. O estudo teve como objetivo estimar a prevalência de HIV e fatores individuais, sociais e programáticos entre AHSH em Salvador, Bahia, Brasil. O estudo transversal foi baseado na análise dos dados da linha de base da coorte PrEP1519 em Salvador. Foram realizadas análises descritivas, bivariadas e multivariadas, usando as dimensões de vulnerabilidade ao HIV como níveis analíticos hierárquicos. Foram usados modelos de regressão logística para estimar as razões de chances (OR) da associação entre as variáveis preditoras e a infecção pelo HIV. A prevalência de infecção pelo HIV entre os 288 AHSH recrutados pelo projeto foi de 5,9% (IC95%: 3,7-9,3). A análise ajustada mostrou uma associação estatisticamente significativa entre a autoidentificação como profissional do sexo (OR = 3,74, IC95%: 1,03-13,60) e a infecção pelo HIV. Outras associações com significância estatística limítrofe foram: uso de aplicativos para achar parceiros sexuais (OR = 3,30, IC95%: 0,98-11,04), menor escolaridade (OR = 3,59, IC95%: 0,96-13,41), história de não ter sido contratado ou de ter sido demitido em função da orientação sexual (OR = 2,88, IC95%: 0,89-9,28) e falta de uso de serviços de saúde como fonte usual de cuidados (OR = 3,14, IC95%: 0,97-10,17). Foi encontrada uma alta prevalência de HIV entre AHSH em Salvador. Além disso, o estudo mostrou que fatores encontrados nas dimensões individual, social e programática estiveram associados à infecção pelo HIV entre esses AHSH. Recomendamos a intensificação das atividades de prevenção combinada entre AHSH.

Los hombres adolescentes que tienen sexo con hombres (AHSH) sufren más vulnerabilidad ante el VIH. El objetivo de este estudio fue estimar la prevalencia de VIH y los factores asociados individuales, sociales, y programáticos asociados entre AHSH en Salvador, Bahia, Brasil. Se trata de un estudio transversal, basado en el análisis de los datos de referencia de la cohorte PrEP1519 en Salvador. Se realizaron análisis descriptivos, bivariados, y multivariados usando las dimensiones de vulnerabilidad respecto al VIH, como los niveles jerárquicos de análisis. Los modelos de regresión logística se usaron para estimar las odds ratios (OR) de la asociación entre las variables predictoras y la infección por VIH. La prevalencia de infección por VIH entre los 288 AHSH reclutados para el proyecto fue 5,9% (IC95%: 3,7-9,3). El análisis ajustado reveló una asociación estadísticamente significativa entre autoidentificarse como un trabajador sexual (OR = 3,74, IC95%: 1,03-13,60) y la infección por VIH. Otras asociaciones con una significación estadística marginal fueron: uso de apps para encontrar pareja sexual (OR = 3,30, IC95%: 0,98-11,04), menos años de educación (OR = 3,59, IC95%: 0,96-13,41), no estar contratado o ser despedido de un trabajo debido a la orientación sexual (OR = 2,88, IC95%: 0,89-9,28), y no usar los servicios de salud como recurso habitual de atención sanitaria (OR = 3,14, IC95%: 0,97-10,17). Se identificó una alta prevalencia de VIH entre AHSH en Salvador. Asimismo, nuestro estudio halló que los factores desde una perspectiva individual, dimensión social, y dimensión programática estuvieron asociados con una infección por VIH entre AHSH. Recomendamos que se intensifiquen las actividades combinadas de prevención contra el VIH para AHSH.

No final de 2017, Brasil adotou a profilaxia pré-exposição do HIV (PrEP) como parte de uma estratégia de prevenção combinada para as populações com maior risco de infecção. Entretanto, o país não dispõe de diretrizes específicas para o uso da PrEP entre adolescentes abaixo de 18 anos de idade. Assim, pesquisadores de diferentes disciplinas de saúde realizaram o PrEP1519, o primeiro estudo de coorte de demonstração da PrEP, atualmente em andamento em três cidades brasileiras - Salvador, Belo Horizonte e São Paulo - entre homens adolescentes que fazem sexo com homens e mulheres transgênero, entre 15 e 19 anos de idade. O estudo busca avaliar a efetividade da PrEP em contextos da vida real. Foram integrados métodos quantitativos e qualitativos para obter dados sobre a aceitabilidade, adoção, uso e adesão à PrEP. Além disso, foram implementados serviços integrados e ambientes acolhedores nas clínicas PrEP1519. O estudo busca descrever os esforços colaborativos das práticas interdisciplinares no desenvolvimento do estudo PrEP1519. A articulação de pesquisadores de diferentes instituições e áreas representa um desafio, mas permite um olhar mais abrangente sobre questões relativas à direção da pesquisa, ao mesmo tempo em que enriquece as decisões necessárias durante as interações e negociações entre diferentes indivíduos, inclusive a equipe de jovens e os participantes. Além disso, reflete o processo de comunicação entre culturas e linguagens, considerando a arena trans-epistêmica da produção de conhecimento sobre HIV, infecções sexualmente transmissíveis, PrEP e outras estratégias de prevenção combinada para adolescentes.

A finales de 2017, Brasil adoptó la profilaxis previa a la exposición al VIH (PrEP) como parte de una estrategia de prevención combinada para las poblaciones de mayor riesgo. Sin embargo, Brasil no tiene directrices específicas para el uso de la PrEP entre los adolescentes < 18 años. Por lo tanto, investigadores de diferentes disciplinas sanitarias llevaron a cabo el PrEP1519, el primer estudio de cohorte de demostración de la PrEP, en curso en tres ciudades brasileñas -Salvador, Belo Horizonte y São Paulo- entre hombres adolescentes que tienen relaciones con hombres y mujeres transexuales, de entre 15 y 19 años. El objetivo de este estudio es evaluar la eficacia de la PPrE en entornos reales. Se integraron métodos cuantitativos y cualitativos para obtener datos sobre la aceptabilidad, la aceptación, el uso y la adherencia de la PrEP. Además, se implementaron servicios integrales y entornos amigables en las clínicas de PrEP1519. Este estudio pretende describir los esfuerzos de colaboración de las prácticas interdisciplinarias en el desarrollo del estudio PrEP1519. La articulación de investigadores de diferentes instituciones y áreas supone un reto; pero también permite ampliar la visión de las cuestiones relativas a la dirección de la investigación, a la vez que enriquece las decisiones que debían tomarse durante las interacciones y negociaciones entre los diferentes individuos, incluyendo el equipo de jóvenes y los participantes. Además, reflexiona sobre el proceso de comunicación entre culturas y lenguas teniendo en cuenta el ámbito trans-epistémico de la producción de conocimiento sobre el VIH, las infecciones de transmisión sexual, la PrEP y otras estrategias de prevención combinada para adolescentes.

Com base na incorporação da profilaxia pré-exposição (PrEP) como estratégia para a prevenção do HIV, e considerando a necessidade de compreender o uso da medicação entre jovens, o artigo analisa as narrativas de homens gays e mulheres transgênero da cidade de Belo Horizonte, Minas Gerais, Brasil, participantes no estudo PrEP1519. A pesquisa qualitativa, baseada na antropologia interpretativa, foi desenvolvida através de 10 entrevistas em profundidade com usuários de PrEP acompanhados durante pelo menos três meses entre outubro e novembro de 2019. Os resultados mostraram que o medicamento era visto como a principal motivação para participar no estudo e como estratégia combinada com o uso de preservativos, seja como prevenção adicional ou assumindo o papel principal. A medicação revelou sinais elaborados pelas performances de gênero e sua relação com outros medicamentos, principalmente a experiência de meninas trans em uso de hormonioterapia. Quanto à socialização do uso da PrEP, as narrativas mostraram que não havia segredo entre os casais, o que não significava a inexistência de estigma em relação à associação com HIV, principalmente no contexto virtual. No ambiente familiar, os participantes relatavam questões sobre a função preventiva da medicação e a natureza voluntária da participação no estudo. As narrativas dos jovens revelaram sentidos plurais atribuídos à medicação e ao seu uso social, compondo as performances tanto dos meninos quanto das meninas. Os sinais atribuídos à medicação indicaram que além da manutenção da saúde, a medicação melhora a vida e a liberdade sexual dos usuários.

Basado en la incorporación de la profilaxis previa a la exposición (PrEP) como una estrategia de prevención contra el VIH, y considerando la necesidad de entender el uso de medicación entre gente joven, este artículo analiza narrativas de hombres gais y mujeres transgénero de Belo Horizonte, Minas Gerais, Brasil, que participan en el estudio PrEP1519. Esta es una investigación cualitativa, basada en la antropología interpretativa, desarrollada por 10 entrevistas en profundidad con usuarios de PrEP, a quienes se les realizó un seguimiento durante al menos tres meses entre octubre y noviembre de 2019. Los resultados mostraron que la medicación fue considerada como la principal motivación de participar en el estudio y como una estrategia combinada con el uso de condones, ya sea como prevención adicional, o asumiendo el papel principal. La medicación reveló signos de estar construida por el desempeño del género y su relación con otros medicamentos, especialmente la experiencia de las chicas trans en la terapia hormonal. Respecto a la socialización del uso del PrEP, las narrativas mostraron que no había secretos entre las parejas, lo cual no significó que no existieran estigmas en la asociación con el VIH, principalmente en contexto virtual. En el ambiente familiar, se informó de cuestiones sobre la función preventiva de la medicación y la naturaleza voluntaria de participar en el estudio. Las narrativas de ellos jóvenes revelaron significados plurales de la medicación y su uso social, formando parte del desempeño tanto de los chicos como de las chicas. Los signos atribuidos a la medicación indicaron que además de mantener la salud, la medicación mejora la vida y la libertad sexual.

Prevalence of syphilis and sexual behavior and practices among adolescents MSM and TrTGW in a Brazilian multi-center cohort for daily use of PrEP / Prevalência de sífilis e comportamento e práticas sexuais entre adolescentes HSH e travestis e mulheres transgênero em um estudo de coorte multicêntrico brasileiro sobre uso diário de PrEP / Prevalencia de sífilis, comportamiento sexual y prácticas entre adolescentes HSH y TrTGW en una cohorte multicéntrica brasileña para el uso diario de PrEP

Syphilis has reemerged as a serious public health problem in Brazil and worldwide, disproportionately affecting men who have sex with men (MSM) and travestis and transgender women (TrTGW). Studies on sexually transmitted infections (STI) in adolescents from these key populations are relatively scarce. This is a Brazilian multi-center, cross study with prevalence analysis, using as baseline the PrEP1519 cohort of sexually active MSM and TrTGW adolescents, recruited from April 2019 to December 2020. Analyses were made using the dimensions of vulnerability to STI/HIV and logistic regression models were conducted to estimate the odds ratios of the association between the predictor variables and positive treponemal test for syphilis at the moment of entry in the study. In total, 677 participants were analyzed; participants' median age was 18.9 years (IQR: 18.1-19.5); 70.5% (477) self-declared as black; 70.5% (474), as homosexuals/gays; and 48 (7.1%), as trans women or travestis. The baseline prevalence of syphilis was 21.3%. In the final logistic regression model, higher chance of syphilis was associated with: self-reported episode of STI in the last 12 months (OR = 5.92; 95%CI: 3.74-9.37), sex worker (OR = 3.39; 95%CI: 1.32-8.78), and < 11 years of schooling (OR = 1.76; 95%CI: 1.13-2.74). The prevalence of syphilis among MSM/TrTGW adolescents aged from 15 to 19 years was alarming, much higher than the described for the general population within this age range and associated with vulnerability factors. This reinforces the urgent need to strengthen public health programs to debate about race, gender, sexuality, and prevention.

A sífilis reemergiu enquanto problema sério de saúde pública no Brasil e no mundo, afetando de maneira desproporcional homens que fazem sexo com homens (HSH), travestis e mulheres transgênero. São relativamente escassos os estudos sobre infecções sexualmente transmissíveis (IST) entre adolescentes pertencentes a essas populações-chave. O estudo transversal multicêntrico brasileiro analisou a prevalência de sífilis na linha de base da coorte PrEP15-19 de HSH, travestis e mulheres transgênero adolescentes, sexualmente ativos, recrutados entre abril de 2019 e dezembro de 2020. As análises foram realizadas com as dimensões de vulnerabilidade a ISTs/HIV, e modelos de regressão logística foram construídos para estimar as razões de chances da associação entre as variáveis preditoras e um teste treponêmico positivo para sífilis na entrada do estudo. Foram analisados 677 participantes. A idade mediana era 18,9 anos (IIQ: 18,1-19,5), 70,5% (477) se autoidentificaram como pretos, 70,5% (474) como homossexuais/gays e 48 (7,1%) como mulheres trans ou travestis. A prevalência de sífilis na linha de base era 21,3%. No modelo final de regressão logística, as seguintes variáveis estiveram associadas com chances maiores de sífilis: autorrelato de episódio de IST nos últimos 12 meses (OR = 5,92; IC95%: 3,74-9,37), profissional do sexo (OR = 3,39; IC95%: 1,32-8,78) e menos de 11 anos de escolaridade (OR = 1,76; IC95%: 1,13-2,74). A prevalência de sífilis entre HSH, travestis e mulheres transgênero adolescentes entre 15 e 19 anos de idade foi alarmante, muito acima da taxa relatada na população geral nesta faixa etária, e esteve associada a fatores de vulnerabilidade. Os achados reforçam a necessidade urgente de fortalecer os programas de saúde pública com a discussão sobre raça, gênero, sexualidade e prevenção.

La sífilis ha resurgido como un problema serio de salud pública en Brasil y en todo el mundo, afectando desproporcionadamente a hombres que tienen sexo con hombres (HSH), travestis y mujeres transgénero (TrTGW). Los estudios de las enfermedades trasmitidas sexualmente (ETS) en adolescentes de estas poblaciones clase son relativamente escasos. Se trata de un estudio transversal brasileño multicéntrico, con análisis de prevalencia de la base de referencia de la cohorte PrEP1519 de hombres activos sexualmente que mantienen sexo con hombres y adolescentes TrTGW, reclutados desde abril de 2019 a diciembre de 2020. Se hicieron análisis, usando las dimensiones de vulnerabilidad a las ETS/VIH, y se realizaron modelos de regresión logística para estimar las odds ratios de la asociación entre las variables predictoras y la prueba treponémica positiva para la sífilis al comenzar el estudio. Se analizaron a 677 participantes. La media de edad fue 18,9 años (IQR: 18,1-19,5), 70,5% (477) se autodeclararon como negros, 70,5% (474) como homosexuales/gays y 48 (7,1%) como mujeres trans o travestis. La base de referencia de prevalencia de sífilis fue 21,3%. En el modelo final de regresión logística, se asociaron con una posibilidad más alta de sífilis: un episodio autoinformado de ETS en los últimos 12 meses (OR = 5,92; IC95%: 3,74-9,37), trabajadores sexuales (OR = 3,39; IC95%: 1,32-8,78) y < 11 años de estudio (OR = 1,76; IC95%: 1,13-2,74). La prevalencia de sífilis entre adolescentes HSH/TrTGW con edades de 15 a 19 años fue alarmante, mucho más que lo descrito para la población general en este rango de edad y asociado con factores de vulnerabilidad. Esto refuerza la urgente necesidad de fortalecer los programas de salud pública, discutiendo cuestiones de raza, género, sexualidad y prevención.

Factors associated to HIV prevalence among adolescent men who have sex with men in Salvador, Bahia State, Brazil: baseline data from the PrEP1519 cohort / Fatores associados à prevalência do HIV entre homens adolescentes que fazem sexo com homens em Salvador, Bahia, Brasil: dados da linha de base da coorte PrEP1519 / Factores asociados a la prevalencia de VIH entre hombres adolescentes que tienen sexo con hombres en Salvador, Bahia, Brasil: datos de referencia de la cohorte PrEP1519

Adolescent men who have sex with men (AMSM) are at a heightened vulnerability for human immunodeficiency virus (HIV). This study aimed to estimate the prevalence of HIV and associated individual, social, and programmatic factors among AMSM in Salvador, Bahia State, Brazil. This is a cross-sectional study which analyzed baseline data from the PrEP1519 cohort in Salvador. Descriptive, bivariate, and multivariate analyses were conducted using the dimensions of vulnerability to HIV as hierarchical levels of analysis. Logistic regression models were used to estimate the odds ratios (OR) of the association between predictor variables and HIV infection. The prevalence of HIV infection among the 288 AMSM recruited to the project was 5.9% (95%CI: 3.7-9.3). Adjusted analysis showed a statistically significant association between self-identifying as a sex worker (OR = 3.74, 95%CI: 1.03-13.60) and HIV infection. Other associations with borderline statistical significance were the use of application programs to find sexual partners (OR = 3.30, 95%CI: 0.98-11.04), low schooling level (OR = 3.59, 95%CI: 0.96-13.41), failing to be hired or being dismissed from a job because of sexual orientation (OR = 2.88, 95%CI: 0.89-9.28), and not using health services as a usual source of care (OR = 3.14, 95%CI: 0.97-10.17). We found a high HIV prevalence among AMSM in Salvador. Furthermore, our study found that individual, social, and programmatic factors were associated with HIV infection among these AMSM. We recommend intensifying HIV combined-prevention activities for AMSM.

Homens adolescentes que fazem sexo com homens (AHSH) apresentam vulnerabilidade aumentada ao HIV. O estudo teve como objetivo estimar a prevalência de HIV e fatores individuais, sociais e programáticos entre AHSH em Salvador, Bahia, Brasil. O estudo transversal foi baseado na análise dos dados da linha de base da coorte PrEP1519 em Salvador. Foram realizadas análises descritivas, bivariadas e multivariadas, usando as dimensões de vulnerabilidade ao HIV como níveis analíticos hierárquicos. Foram usados modelos de regressão logística para estimar as razões de chances (OR) da associação entre as variáveis preditoras e a infecção pelo HIV. A prevalência de infecção pelo HIV entre os 288 AHSH recrutados pelo projeto foi de 5,9% (IC95%: 3,7-9,3). A análise ajustada mostrou uma associação estatisticamente significativa entre a autoidentificação como profissional do sexo (OR = 3,74, IC95%: 1,03-13,60) e a infecção pelo HIV. Outras associações com significância estatística limítrofe foram: uso de aplicativos para achar parceiros sexuais (OR = 3,30, IC95%: 0,98-11,04), menor escolaridade (OR = 3,59, IC95%: 0,96-13,41), história de não ter sido contratado ou de ter sido demitido em função da orientação sexual (OR = 2,88, IC95%: 0,89-9,28) e falta de uso de serviços de saúde como fonte usual de cuidados (OR = 3,14, IC95%: 0,97-10,17). Foi encontrada uma alta prevalência de HIV entre AHSH em Salvador. Além disso, o estudo mostrou que fatores encontrados nas dimensões individual, social e programática estiveram associados à infecção pelo HIV entre esses AHSH. Recomendamos a intensificação das atividades de prevenção combinada entre AHSH.

Los hombres adolescentes que tienen sexo con hombres (AHSH) sufren más vulnerabilidad ante el VIH. El objetivo de este estudio fue estimar la prevalencia de VIH y los factores asociados individuales, sociales, y programáticos asociados entre AHSH en Salvador, Bahia, Brasil. Se trata de un estudio transversal, basado en el análisis de los datos de referencia de la cohorte PrEP1519 en Salvador. Se realizaron análisis descriptivos, bivariados, y multivariados usando las dimensiones de vulnerabilidad respecto al VIH, como los niveles jerárquicos de análisis. Los modelos de regresión logística se usaron para estimar las odds ratios (OR) de la asociación entre las variables predictoras y la infección por VIH. La prevalencia de infección por VIH entre los 288 AHSH reclutados para el proyecto fue 5,9% (IC95%: 3,7-9,3). El análisis ajustado reveló una asociación estadísticamente significativa entre autoidentificarse como un trabajador sexual (OR = 3,74, IC95%: 1,03-13,60) y la infección por VIH. Otras asociaciones con una significación estadística marginal fueron: uso de apps para encontrar pareja sexual (OR = 3,30, IC95%: 0,98-11,04), menos años de educación (OR = 3,59, IC95%: 0,96-13,41), no estar contratado o ser despedido de un trabajo debido a la orientación sexual (OR = 2,88, IC95%: 0,89-9,28), y no usar los servicios de salud como recurso habitual de atención sanitaria (OR = 3,14, IC95%: 0,97-10,17). Se identificó una alta prevalencia de VIH entre AHSH en Salvador. Asimismo, nuestro estudio halló que los factores desde una perspectiva individual, dimensión social, y dimensión programática estuvieron asociados con una infección por VIH entre AHSH. Recomendamos que se intensifiquen las actividades combinadas de prevención contra el VIH para AHSH.

Interdisciplinarity in HIV prevention research: the experience of the PrEP1519 study protocol among adolescent MSM and TGW in Brazil / Interdisciplinaridade na pesquisa sobre prevenção do HIV: a experiência do protocolo de estudo PrEP1519 entre HSH adolescentes e mulheres trans no Brasil / Interdisciplinariedad en la investigación de la prevención del VIH: la experiencia del protocolo de estudio PrEP1519 entre adolescentes HSH y TGW en Brasil

At the end of 2017, Brazil adopted HIV pre-exposure prophylaxis (PrEP) as part of a combination prevention strategy for the most at-risk populations. However, Brazil does not have specific guidelines for PrEP use among adolescents aged < 18 years. Therefore, researchers from different health disciplines conducted PrEP1519, the first PrEP demonstration cohort study, ongoing in three Brazilian cities - Salvador, Belo Horizonte, and São Paulo - among adolescent men who have sex with men and transgender women, aged 15-19 years. This study aims to evaluate the effectiveness of PrEP in real-world settings. Quantitative and qualitative methods were integrated to obtain data on PrEP acceptability, uptake, use, and adherence. Moreover, comprehensive services and friendly environments were implemented in the PrEP1519 clinics. This study aims to describe the collaborative efforts of interdisciplinary practices in the development of the PrEP1519 study. The articulation of researchers from different institutions and areas is challenging; but it also allows for a broader outlook on questions regarding the direction of the research, while enriching the decisions needed to be taken during the interactions and negotiations among the different individuals, including the youth team and participants. Furthermore, it reflects on the communication process between cultures and languages considering the trans-epistemic arena of knowledge production about HIV, sexually transmitted infections, PrEP, and other combination prevention strategies for adolescents.

No final de 2017, Brasil adotou a profilaxia pré-exposição do HIV (PrEP) como parte de uma estratégia de prevenção combinada para as populações com maior risco de infecção. Entretanto, o país não dispõe de diretrizes específicas para o uso da PrEP entre adolescentes abaixo de 18 anos de idade. Assim, pesquisadores de diferentes disciplinas de saúde realizaram o PrEP1519, o primeiro estudo de coorte de demonstração da PrEP, atualmente em andamento em três cidades brasileiras - Salvador, Belo Horizonte e São Paulo - entre homens adolescentes que fazem sexo com homens e mulheres transgênero, entre 15 e 19 anos de idade. O estudo busca avaliar a efetividade da PrEP em contextos da vida real. Foram integrados métodos quantitativos e qualitativos para obter dados sobre a aceitabilidade, adoção, uso e adesão à PrEP. Além disso, foram implementados serviços integrados e ambientes acolhedores nas clínicas PrEP1519. O estudo busca descrever os esforços colaborativos das práticas interdisciplinares no desenvolvimento do estudo PrEP1519. A articulação de pesquisadores de diferentes instituições e áreas representa um desafio, mas permite um olhar mais abrangente sobre questões relativas à direção da pesquisa, ao mesmo tempo em que enriquece as decisões necessárias durante as interações e negociações entre diferentes indivíduos, inclusive a equipe de jovens e os participantes. Além disso, reflete o processo de comunicação entre culturas e linguagens, considerando a arena trans-epistêmica da produção de conhecimento sobre HIV, infecções sexualmente transmissíveis, PrEP e outras estratégias de prevenção combinada para adolescentes.

A finales de 2017, Brasil adoptó la profilaxis previa a la exposición al VIH (PrEP) como parte de una estrategia de prevención combinada para las poblaciones de mayor riesgo. Sin embargo, Brasil no tiene directrices específicas para el uso de la PrEP entre los adolescentes < 18 años. Por lo tanto, investigadores de diferentes disciplinas sanitarias llevaron a cabo el PrEP1519, el primer estudio de cohorte de demostración de la PrEP, en curso en tres ciudades brasileñas -Salvador, Belo Horizonte y São Paulo- entre hombres adolescentes que tienen relaciones con hombres y mujeres transexuales, de entre 15 y 19 años. El objetivo de este estudio es evaluar la eficacia de la PPrE en entornos reales. Se integraron métodos cuantitativos y cualitativos para obtener datos sobre la aceptabilidad, la aceptación, el uso y la adherencia de la PrEP. Además, se implementaron servicios integrales y entornos amigables en las clínicas de PrEP1519. Este estudio pretende describir los esfuerzos de colaboración de las prácticas interdisciplinarias en el desarrollo del estudio PrEP1519. La articulación de investigadores de diferentes instituciones y áreas supone un reto; pero también permite ampliar la visión de las cuestiones relativas a la dirección de la investigación, a la vez que enriquece las decisiones que debían tomarse durante las interacciones y negociaciones entre los diferentes individuos, incluyendo el equipo de jóvenes y los participantes. Además, reflexiona sobre el proceso de comunicación entre culturas y lenguas teniendo en cuenta el ámbito trans-epistémico de la producción de conocimiento sobre el VIH, las infecciones de transmisión sexual, la PrEP y otras estrategias de prevención combinada para adolescentes.

When prevention is the best remedy: HIV pre-exposure prophylaxis (PrEP) among adolescents gays and transgender women in Belo Horizonte, Minas Gerais State, Brazil / Quando a prevenção é o melhor remédio: profilaxia pré-exposição do HIV (PrEP) entre adolescentes gays e mulheres transgênero em Belo Horizonte, Minas Gerais, Brasil / Cuando la prevención es el mejor remedio: profilaxis previa a la exposición al VIH (PrEP) entre adolescentes gays y mujeres transgénero en Belo Horizonte, Minas Gerais, Brasil

Based on the incorporation of pre-exposure prophylaxis (PrEP) as an HIV prevention strategy and considering the need to comprehend the use of medication among young people, this article analyzes narratives of gay men and transgender women from Belo Horizonte, Minas Gerais State, Brazil, participating in the PrEP1519 study. This is a qualitative research, based on the interpretative anthropology, developed by 10 in-depth interviews with PrEP users followed-up for at least three months between October and November 2019. The results showed that the drug was seen as the main motivation for participating in the study and as a strategy combined with the use of condoms, whether as additional prevention, or assuming the leading role. The medication revealed signs built by the gender performances and their relation to other medications, especially the experience of trans girls in hormonal therapy. Regarding the socialization of the use of PrEP, the narratives showed that there was no secret between the couples, which did not meant that stigmas on the association with HIV did not exist, mainly in the virtual context. In the family environment, they reported questions about the preventive function of the medication and the voluntary nature of the participation in the study. The youth's narratives revealed plural meanings of the medication and its social use, composing both the boys' and girls' performances. The signs attributed to the medication indicated that in addition to maintenance of health, the medication improves life and sexual freedom.

Effects of the COVID-19 pandemic on the sexual and mental health of adolescent and adult men who have sex with men and transgender women participating in two PrEP cohort studies in Brazil: COBra study protocol.

INTRODUCTION: The COVID-19 pandemic and its control measures have impacted health and healthcare provision in various levels. Physical distancing measures, for instance, may affect sexual health, impacting access to HIV prevention supplies and changing sexual behaviour, as well as mental health, increasing feelings of unsafety and weakening community support ties. These effects can be worsened among socially marginalised groups, such as men who have sex with men (MSM) and transgender women (TGW). Brazil is among the countries most affected by COVID-19 in the world, where control measures have been inconsistently implemented. We aim to investigate the effects of the COVID-19 pandemic on the sexual and mental health of adolescent and adult MSM and TGW in Brazil. METHODS: Convergent mixed-method prospective cohort study, nested in two ongoing HIV pre-exposure prophylaxis (PrEP) cohorts in Brazil, named PrEP1519 and Combina. Participants will be invited to answer, at baseline and after 6 months, a questionnaire about the effects of the COVID-19 pandemic on sexual behaviour, HIV prevention and mental health. Data on HIV infection and sexually transmitted infections (STI) will be collected as part of routine follow-up from the cohorts. Main outcome measures (HIV infection, STI and depression symptoms) will be observed within 12 months after baseline. Sample size is estimated at 426 participants. Complementarily, 50 participants will be invited to in-depth interviews through video calls or interactive voice response, and 20 will be invited to chronicle their lives during the pandemic through digital diaries. Triangulation will be done across qualitative methods and with the quantitative data. ETHICS AND DISSEMINATION: The study was approved by Research Ethics Committees from the Brazilian Universities coordinating the study. Findings will be published in scientific journals and presented at meetings. Informative flyers will be elaborated to communicate study findings to participants and key stakeholders.

Virologic and immunologic effectiveness of darunavir-based salvage therapy in HIV-1-infected adults in a Brazilian clinical practice setting: results of a multicenter and retrospective cohort study

Background: Darunavir has been proven efficacious for antiretroviral-experienced HIV-1-infected patients in randomized trials. However, effectiveness of darunavir-based salvage therapy is understudied in routine care in Brazil. Methods: Retrospective cohort study of HIV-1-infected patients from three public referral centers in Belo Horizonte, who received a darunavir-based therapy between 2008 and 2010, after virologic failure. Primary endpoint was the proportion of patients with viral load <50 copies/mL at week 48. Change in CD4 cell count was also evaluated. Outcome measures were analyzed on an intent-to-treat basis applied to observational studies. Sensitivity analysis was conducted to evaluate the impact of missing data at week 48. Predictors of virologic failure were examined using rare-event, finite sample, bias-corrected logistic regression. Results: Among 108 patients, the median age was 44.2 years, and 72.2% were male. They had long-standing HIV-1 infection (median 11.6 years) and advanced disease (76.9% had an AIDS-defining event). All patients had previously received protease inhibitors and nucleoside reverse transcriptase inhibitors, 75% nonnucleoside reverse transcriptase inhibitors, and 4.6% enfuvirtide. The median length of protease inhibitor use was 8.9 years, and 90.8% of patients had prior exposure to unboosted protease inhibitor. Genotypic resistance profile showed a median of three primary protease inhibitor mutations and 10.2% had three or more darunavir resistance-associated mutations. Virologic success at week 48 was achieved by 78.7% (95% CI = 69.7–86%) of patients and mean CD4 cell count increase from baseline was 131.5 cells/μL (95% CI = 103.4–159.6). In multiple logistic regression analysis, higher baseline viral load (RR = 1.04 per 10,000 copies/mL increase; 95% CI = 1.01–1.09) and higher number of darunavir resistance-associated mutations (RR = 1.23 per each; 95% CI = 0.95–1.48) ...

Virologic and immunologic effectiveness at 48 weeks of darunavir-ritonavir-based regimens in treatment-experienced persons living with HIV-1 infection in clinical practice: a multicenter Brazilian cohort.

INTRODUCTION: Published data addressing the effectiveness of darunavir-ritonavir (DRV/r)-based therapy for multiexperienced patients in developing countries are scarce. This study evaluated the 48-week virologic and immunologic effectiveness of salvage therapy based on DRV/r for the treatment of multidrug-experienced HIV-1-infected adults in Brazil. MATERIALS AND METHODS: A multicenter retrospective cohort study was carried out with multidrug-experienced adults who were on a failing antiretroviral therapy and started a DRV/r-based salvage therapy between 2008 and 2010. The primary effectiveness end point was the proportion of patients with virologic success (plasma HIV-1 RNA <50 copies/mL at week 48). RESULTS: At 48 weeks, 73% of the patients had HIV-RNA <50 copies/mL and a mean increase of 108 CD4 cells/mm(3). Higher baseline viral load, lower baseline CD4 count, younger age, and 3 or more DRV/r-associated resistance mutations were significantly predictive of virologic failure. Concomitant use of raltegravir was strongly associated with virologic success. CONCLUSION: The use of DRV/r-based regimens for salvage therapy is an effective strategy in the clinical care setting of a developing country.
