RESUMO

Many barriers to human immunodeficiency virus (HIV) testing among Black people exist. This study analysed the association between race/skin colour and lifetime HIV testing among adolescent men who have sex with men (AMSM) and transgender women (ATGW) in three Brazilian cities. This cross-sectional study was nested within the PrEP1519 cohort, a multicentre study of AMSM and ATGW aged 15-19 years in Belo Horizonte, Salvador, and São Paulo, Brazil. The outcome variable was the lifetime HIV testing (no or yes). The main exposure variable was self-reported race/skin colour as White and a unique Black group (composed of Pardo-mixed colour and Black, according to the Brazilian classification). Descriptive statistics and bivariate and multiple logistic regression analyses were conducted to estimate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) to determine the association between the main exposure and outcome, adjusted for covariates. White adolescents were tested more frequently than the unique Black group (64.0% vs. 53.7%, respectively; Ρ = 0.001). Multiple logistic regression analysis showed that the unique Black group of AMSM and ATGW had 26% (adjusted OR [aOR], 0.74; 95% CI, 0.55-0.98) and 38% (aOR, 0.62; 95% CI, 0.45-0.87) lower odds of being tested for HIV in a lifetime than Whites in model 1 and 2, respectively. Our findings highlight the role of racism in lifetime HIV testing among AMSM and ATGW. Therefore, an urgent need for advances exists in public policies to combat racism in Brazil.


RESUMEN: Existen numerosas barreras para la realización de las pruebas del virus de la inmunodeficiencia humana (VIH) entre la población negra. Este estudio analizó la asociación entre la raza/color de piel y haber realizado pruebas de VIH a lo largo de la vida entre hombres adolescentes que tienen sexo con hombres (AHSH) y mujeres transgénero (AMTG) en tres ciudades brasileñas. Este estudio transversal es parte de la cohorte PrEP1519, un estudio multicéntrico de AHSH y AMTG de 15 a 19 años en Belo Horizonte, Salvador y São Paulo, Brasil. La variable de resultado fue haber realizado la prueba del VIH a lo largo de la vida (no o sí). La variable de exposición principal fue la raza/color de piel autoinformada, categorizada como blanca y un grupo negro único (compuesto por color pardo/mixto y negro, según la clasificación brasileña). Se realizaron estadísticas descriptivas y análisis de regresión logística bivariada y multivariada para estimar los odds ratios (OR) ajustados y los intervalos de confianza del 95% (IC del 95%) con el fin de determinar la asociación entre la exposición principal y el resultado, ajustado por covariables. Los adolescentes blancos se hicieron la prueba del VIH con más frecuencia que el grupo negro único (64,0% frente a 53,7%, respectivamente; Ρ = 0,001). El análisis de regresión logística múltiple reveló que el grupo negro único de AHSH y AMTG tenía 26% (OR ajustado [aOR], 0,74; IC 95%, 0,55­0,98) y 38% (aOR, 0,62; IC 95%, 0,45­0,87) menores probabilidades de realizarse la prueba del VIH a lo largo de su vida que los blancos en los modelos 1 y 2, respectivamente. Nuestros hallazgos resaltan la influencia del racismo en la realización de pruebas de VIH a lo largo de la vida entre AHSH y AMTG. Por lo tanto, es urgente avanzar en la implementación de políticas públicas para combatir el racismo en Brasil.

RESUMO

The Access to COVID-19 Tools Accelerator (ACT-A) is a multistakeholder initiative quickly constructed in the early months of the COVID-19 pandemic to respond to a catastrophic breakdown in global cooperation. ACT-A is now the largest international effort to achieve equitable access to COVID-19 health technologies, and its governance is a matter of broad public importance. We traced the evolution of ACT-A's governance through publicly available documents and analysed it against three principles embedded in the founding mission statement of ACT-A: participation, transparency, and accountability. We found three challenges to realising these principles. First, the roles of the various organisations in ACT-A decision making are unclear, obscuring who might be accountable to whom and for what. Second, the absence of a clearly defined decision making body; ACT-A instead has multiple centres of legally binding decision making and uneven arrangements for information transparency, inhibiting meaningful participation. Third, the nearly indiscernible role of governments in ACT-A, raising key questions about political legitimacy and channels for public accountability. With global public health and billions in public funding at stake, short-term improvements to governance arrangements can and should now be made. Efforts to strengthen pandemic preparedness for the future require attention to ethical, legitimate arrangements for governance.

RESUMO

Using baseline data from the PrEP1519 cohort, in this article we aimed to analyze: (i) the effectiveness of demand creation strategies (DCS) to enroll adolescent men who have sex with men (AMSM) and adolescent transgender women (ATGW) into an HIV combination prevention study in Brazil; (ii) the predictors of DCS for adolescents' enrollment; and (iii) the factors associated with DCS by comparing online and face-to-face strategies for enrollment. The DCS included peer recruitment (i.e., online and face-to-face) and referrals from health services and non-governmental organizations (NGOs). AMSM and ATGW who agreed to participate in the study could opt to enroll in either PrEP (PrEP arm) or to use other prevention methods (non-PrEP arm). Bivariate and multivariate analyses were conducted and logistic regression odds ratios were estimated. The DCS reached 4529 AMSM and ATGW, the majority of which were derived online (73.8%). Of this total, 935 (20.6%) enrolled to participate (76.6% in PrEP arm and 23.4% in non-PrEP arm). The effectiveness of enrolling adolescents into both arms was greater via direct referrals (235/382 and 84/382, respectively) and face-to-face peer recruitment (139/670 and 35/670, respectively) than online (328/3342). We found that a combination under DCS was required for successful enrollment in PrEP, with online strategies majorly tending to enroll adolescents of a higher socioeconomic status. Our findings reinforce the need for DCS that actively reaches out to all adolescents at the greatest risk for HIV infection, irrespective of their socioeconomic status.

RESUMO

This systematic review aims to estimate the prevalence of sarcopenia in people living with HIV (PLHIV) and to assess whether there is a difference between the muscle mass of PLHIV and people living without HIV. A systematic review of randomized controlled trials, cohort studies, cross-sectional and case-control studies was carried out. PLHIV over 18 years of age and that had their muscle mass evaluated by dual-energy X-ray absorptiometry were included. Overall, 4,376 studies were found, of which 118 had their full texts evaluated. A total of 5,532 people living with HIV and 2,986 people living without HIV were identified in 41 studies. The frequency of sarcopenia defined by low muscle mass (Baumgartner's operational definition) alone was 30.3% (95%CI 24.3%, 37.1%) and the frequency of sarcopenia defined by low muscle mass with low muscle strength (EWGSOP definition) was 4.5% (95%CI 1.3%, 13.9%), p-value = 0.0006. The standardized mean differences of muscle mass between PLHIV and controls was -0.211 units of standard deviation (95%CI -0.419, -0.003). In the meta-regression analysis muscle mass mean difference was associated with BMI, CD4, percentage of subjects on ART, and study design. PLHIV have a lower muscle mass when compared to people living without HIV. This difference appears to be attenuated by higher BMI, CD4 levels, and the percentage of subjects using ART. Furthermore, the frequencies of sarcopenia assessed by the operational definition of Baumgartner and the EWGSOP are not comparable and cannot be interchanged in PLHIV.

RESUMO

In the space of four decades, Brazil has faced two serious pandemics: human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and Coronavirus disease 2019 (COVID-19). The country's response to HIV/AIDS was coordinated by several stakeholders and recognised the importance of scientific evidence in guiding decision-making, and a network offering monitoring and antiretroviral treatment was provided through coordinated efforts by the country's universal health system. Conversely, the lack of a centrally coordinated strategy and misalignment between government ministries regarding the COVID-19 pandemic response, together with the denial of scientific evidence, promotion of ineffective treatments and insufficient vaccination efforts, have all led to the uncontrolled spread of infection, the near-total collapse of the health system and excess deaths.

RESUMO

Frequent contact with hazardous materials makes waste collection a potentially unhealthy activity. This article assesses the perception of waste management workers regarding work-related accidents in domestic and health service contexts in Brazil. Six focus groups were performed between June 2014 and August 2015. The aims of this study were to apprehend different aspects of the participants' health, workers' experiences of work-related accidents and perception of risks. Cuts and puncture injuries were reported most frequently in the line of work and were often considered as irrelevant. Immunization against hepatitis B was not common among all workers, which increases the risk of infection for those individuals. Finally, it is considered urgent to consolidate an inclusive space in which workers can have discussions on their health.

RESUMO

As more urban solid waste is generated, managing it becomes ever more challenging and the potential impacts on the environment and human health also become greater. Handling waste - including collection, treatment and final disposal - entails risks of work accidents. This article assesses the perception of waste management workers regarding work-related accidents in domestic and health service contexts in Belo Horizonte, Brazil. These perceptions are compared with national data from the Ministry of Social Security on accidents involving workers in solid waste management. A high proportion of accidents involves cuts and puncture injuries; 53.9% among workers exposed to domestic waste and 75% among those exposed to health service waste. Muscular lesions and fractures accounted for 25.7% and 12.5% of accidents, respectively. Data from the Ministry of Social Security diverge from the local survey results, presumably owing to under-reporting, which is frequent in this sector. Greater commitment is needed from managers and supervisory entities to ensure that effective measures are taken to protect workers' health and quality of life. Moreover, workers should defend their right to demand an accurate registry of accidents to complement monitoring performed by health professionals trained in risk identification. This would contribute to the improved recovery of injured workers and would require managers in waste management to prepare effective preventive action.

RESUMO

Infection with the hepatitis B and C viruses may occur through contact with infected body fluids, including injury with infected sharps. Collectors of domestic or healthcare wastes are potentially exposed to these infections. The aim of this article is to investigate the risk factors associated with the prevalence of hepatitis B and C viruses (HBV and HCV) infection among domestic and healthcare waste workers in Belo Horizonte, Brazil. A cross-sectional study of hepatitis B and C infection was conducted from November 2014 to January 2015, through blood sample collection and interviews about socio-demographic factors with 61 workers exposed to healthcare waste ('exposed') and 461 exposed only to domestic wastes ('unexposed'). The prevalence of antibodies to HCV (Anti-HCV) antibodies was 3.3% in 'exposed' workers and 0.9% in 'unexposed', and of antibody to hepatitis B core antigen (Anti-HBc) was 9.8% and 5.6% in 'exposed' and 'unexposed' workers, respectively. Only 207 (44.9%) of those exposed to domestic waste and 45 (73.8%) of those handling healthcare waste were effectively immunised against hepatitis B virus (HBV). Exposures to domestic waste and to healthcare wastes were associated with similar risks of infection with HBV. The risk of hepatitis C virus (HCV) infection was marginally higher among healthcare waste workers compared with domestic waste workers, probably because of needlestick accidents owing to deficient sharps management systems. Immunisation against hepatitis B and screening tests to ensure the success of vaccination should be a condition for recruitment for both groups of waste workers.

RESUMO

Understanding the social conditions and immunological characteristics that allow some human immunodeficiency virus (HIV)-exposed patients to remain uninfected represents an on-going challenge. In this study, the socio-demographic and sexual behaviour characteristics and immune activation profiles of uninfected individuals exposed to HIV-infected partners were investigated. A confidential and detailed questionnaire was administered and venous blood was tested using HIV-1/enzyme immunoassays, plasma HIV-1 RNA levels/bDNA and immunophenotyping/flow cytometry to determine the frequencies of CD4 and CD8 T cells expressing activation markers. The data analysis showed significant differences (p < 0.05) for immune parameters in individuals who were uninfected, albeit exposed to HIV-infected partners, compared with unexposed individuals. In particular, the exposed, uninfected individuals had a higher frequency (median, minimum-maximum) of CD4⁺HLA-DR⁺ (4.2, 1.8-6.1), CD8⁺HLA-DR⁺ (4.6, 0.9-13.7), CD4⁺CD45RO⁺ (27.5, 14.2-46.6), CD4⁺CD45RO⁺CD62L⁺ (46.7, 33.9-67.1), CD8⁺CD45RA⁺HLA-DR⁺ (12.1, 3.4-35.8) and CD8⁺CD45RO⁺HLA-DR⁺ (9.0, 3.2-14.8) cells, a decreased percentage of CD8⁺CD28⁺ cells (11.7, 4.5-24.0) and a lower cell-surface expression of Fcγ-R/CD16 on monocytes (56.5, 22.0-130.0). The plasma HIV-1 RNA levels demonstrated detectable RNA virus loads in 57% of the HIV-1⁺ female partners. These findings demonstrate an activation profile in both CD4 and CD8 peripheral T cells from HIV-1 exposed seronegative individuals of serodiscordant couples from a referral centre in Belo Horizonte, state of Minas Gerais.

RESUMO

The presence of transmitted human immunodeficiency virus (HIV)-1 drug-resistance (TDR) at the time of antiretroviral therapy initiation is associated with failure to achieve viral load (VL) suppression. Here, we report TDR surveillance in a specific population of men who have sex with men (MSM) in Belo Horizonte, Brazil. In this study, the rate of TDR was evaluated in 64 HIV-infected individuals from a cohort of MSM between 1996-June 2012. Fifty-four percent had a documented recent HIV infection, with a seroconversion time of less than 12 months. The median CD4+T lymphocyte count and VL were 531 cells/mm3 and 17,746 copies/mL, respectively. Considering the surveillance drug resistance mutation criteria, nine (14.1%) patients presented TDR, of which three (4.7%), five (7.8%) and four (6.2%) had protease inhibitors, resistant against nucleos(t)ide transcriptase inhibitors and against non-nucleoside reverse-transcriptase inhibitors mutations, respectively. Two of the patients had multi-drug-resistant HIV-1. The most prevalent viral subtype was B (44, 68.8%), followed by subtype F (11, 17.2%). This study shows that TDR may vary according to the population studied and it may be higher in clusters of MSM.

RESUMO

HIV Pre-exposure prophylaxis (PrEP) is an effective prevention tool, but there are still few studies about PrEP uptake among adolescents. We aimed to analyze the PrEP uptake process and factors associated with daily oral PrEP initiation among adolescent men who have sex with men (aMSM) and transgender women (aTGW) in Brazil. Baseline data from the first demonstration PrEP cohort study among aMSM and aTGW 15-19 years old (yo) ongoing in three large Brazilian cities (PrEP1519). After completing informed consent procedures, participants were enrolled in the cohort from February/2019 to February/2021. A socio-behavioral questionnaire was applied. Factors associated with PrEP initiation were assessed using a logistic regression model with adjusted prevalence ratios (aPR) and 95% confidence intervals (95%CI). Among recruited participants, 174 (19,2%) were aged 15-17 yo and 734 (80,8%) 18-19 yo. The rate of PrEP initiation was 78.2% and 77.4% for 15-17 yo and 18-19 yo, respectively. Factors associated with PrEP initiation were: black or mixed race (aPR 2.31; 95%CI: 1.10-4.84) among the younger adolescents 15-17 yo; experienced violence and/or discrimination due to their sexual orientation or gender identity (aPR 1.21; 95%CI: 1.01-1.46); transactional sex (aPR 1.32; 95%CI: 1.04-1.68); and having had between 2 to 5 sexual partners in the previous three months (aPR 1.39; 95%CI: 1.15-1.68) among those 18-19 yo. Unprotected receptive anal intercourse in the previous six months was associated with PrEP initiation in both age groups (aPR 1.98; 95%CI: 1.02-3.85 and aPR 1.45; 95%CI: 1.19-1.76 among 15-17 yo and 18-19 yo, respectively). The biggest challenge to promoting PrEP use for aMSM and aTGW was in the first steps of the PrEP uptake process. Once they were linked to the PrEP clinic, initiation rates were high.

RESUMO

PURPOSE: This study analyzed the sociodemographic and behavioral characteristics of adolescent men who have sex with men (aMSM) and transgender women (aTGW) initiating oral pre-exposure prophylaxis (PrEP) in human immunodeficiency virus (HIV) prevention clinics. METHODS: PrEP1519 is a prospective, multicenter, open-label PrEP demonstration cohort study of aMSM and aTGW aged 15-19 years living in three large Brazilian capital cities. For this analysis, we included adolescents who enrolled in PrEP1519 from February 2019 to August 2021. Adolescents who visited PrEP clinics were classified into four groups based on PrEP eligibility and on their decision to use PrEP: (1) ineligible for same-day PrEP initiation; (2) eligible for same-day PrEP initiation, initiated PrEP at first visit; (3) eligible for PrEP initiation, initiated PrEP after the first visit; and (4) eligible for same-day PrEP initiation but declined. The groups that were eligible for same-day PrEP initiation were compared using the Chi-square and Fisher's exact tests. RESULTS: Of the 1,254 adolescents enrolled in the PrEP1519 study, 61 (4.9%) were considered ineligible for same-day PrEP initiation. Of the 1,193 eligible for same-day PrEP initiation, 1,113 (93.3%) initiated PrEP [1,054 initiated PrEP in the first visit (88.3%) and 59 in subsequent visits (4.9%)] and 80 (6.7%) did not. Despite 90% of the PrEP decliners reporting a low risk of HIV infection, most reported condomless anal sex in the past six months (70%). DISCUSSION: Same-day PrEP initiation among aMSM and aTGW was high, highlighting that this strategy was important to promote PrEP initiation among adolescents with increased vulnerability to HIV in Brazil.

RESUMO

PURPOSE: To explore legal and ethical challenges related to adolescents' participation in human immunodeficiency virus (HIV) research that may affect their best interests. METHODS: We analyzed the ethical principles and legal aspects of the participation of 15-17-year-old men who have sex with men and transgender women in the pre-exposure prophylaxis (PrEP) 1519 study, a PrEP demonstration cohort study in three Brazilian cities. The analyses of ethics review committees' (ERCs) evaluations and court decisions followed ethical and human rights principles. An HIV vulnerability score was created, and descriptive statistics and multivariate logistic regression were performed using data from 347 participants. RESULTS: The ERCs evaluated the benefits and risks of research participation, all finding that the benefits outweighed the risks. ERCs deferred responsibility for decisions about waiving parental consent to the judiciary. State courts reached different decisions about waiving parental consent, reflecting variation in recognition of adolescents' evolving capacities and the adolescent as a subject of sexual rights and the primary agent capable of deciding on their health and best interests. The most vulnerable adolescent participants were found in sites where the blanket waiver was in place. DISCUSSION: Judicializing the ethical review process is detrimental to fulfilling the ethical principle of justice and vulnerable adolescents' access to health research. ERCs must be sufficiently independent and autonomous and have the capacity to respect, protect, and help fulfill the rights of participants while ensuring the generation of adequate evidence to inform public health practice.

RESUMO

PURPOSE: This study aimed to describe pre-exposure prophylaxis (PrEP) for HIV discontinuation in adolescent men who have sex with men (aMSM) and adolescent transgender women (aTGW) and to identify factors associated with discontinuation. METHODS: The PrEP1519 study included a cohort of aMSM and aTGW aged 15-19 years old, and it was conducted in three large Brazilian capital cities. For this analysis, we included adolescents who initiated PrEP. PrEP discontinuation was defined as no possession of PrEP pills for >90 days. Kaplan-Meier curves were used to analyze the probabilities of discontinuation, and survival distributions stratified by covariates were compared using log-rank or Wilcoxon tests. Cox regression models were used to estimate the adjusted hazard ratio (aHR) with a 95% confidence interval (95% CI). RESULTS: We included 908 adolescents, 829 (91.30%) aMSM and 79 (8.70%) aTGW, most of whom were 18-19 years (80.29%). The incidence rate of discontinuation was 75.6 per 100 person-years. The probability of discontinuation was 52.61% in the first year. The multivariate analysis demonstrated that the aTGW (aHR = 1.63; 95% CI: 1.02-1.64) and adolescents with a medium (aHR = 1.29; 95% CI: 1.02-1.64) or low (aHR = 1.65; 95% CI: 1.29-2.12) perceived risk of HIV infection had an increased risk of discontinuation, whereas the adolescents with a partner living with HIV had a lower risk of discontinuation (aHR = 0.57; 95% CI: 0.35-0.91). DISCUSSION: Adolescents with a high risk for discontinuation may need additional support that emphasizes the value of PrEP as a tool for HIV prevention because PrEP discontinuation was associated with a disconnect between HIV risk perception and HIV prevention.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

The purpose of this study is to estimate the survival probability of patients following their first admission for the treatment of AIDS to an infectious disease reference hospital in Belo Horizonte, Brazil, during 2005. Study subjects were monitored during a 12-month period to identify factors associated with survival probability. Late diagnosis was recorded among many of the 250 study subjects: almost half (44.8%) were diagnosed less than 30 days prior to or during their hospitalization. A high mortality rate was also detected: 39.6% of the subjects died during the 12 months of monitoring. The cumulative survival probability of the cohort group was estimated at 68.0% after 3 months and at 61.2% after 12 months. However, certain patient subgroups analyzed had even lower cumulative survival probabilities after 12 months of monitoring: if diagnosed during hospitalization, it was estimated at only 48.0% and those with no record of antiretroviral treatment had a 48.5% cumulative survival probability. Patients with severe anemia had the lowest survival probability, similar among the two lymphocyte count groups (<1000 mm(3) and ≥1000 mm(3)), the former with a 45.5% survival probability and the latter with a 46.7% one. The proportional death risk was 2.5-fold higher for men residing in other area than the capital city of the State of Minas Gerais and greater metropolitan region when compared with women residing there. The findings of this study highlight the importance of early diagnosis for predicting patient survival and reinforce the necessity of facilitating HIV diagnosis.
