Same-day initiation of oral pre-exposure prophylaxis among gay, bisexual, and other cisgender men who have sex with men and transgender women in Brazil, Mexico, and Peru (ImPrEP): a prospective, single-arm, open-label, multicentre implementation study

BACKGROUND

Although gay, bisexual, and other cisgender men who have sex with men (MSM) and transgender women have the highest HIV burden in Latin America, pre-exposure prophylaxis (PrEP) implementation is poor. We aimed to assess the feasibility of same-day oral PrEP delivery in Brazil, Mexico, and Peru.

METHODS

Implementation PrEP (ImPrEP) was a prospective, single-arm, open-label, multicentre PrEP implementation study conducted in Brazil (14 sites), Mexico (four sites), and Peru (ten sites). MSM and transgender women were eligible to participate if they were aged 18 years or older, HIV-negative, and reported one or more prespecified criteria. Enrolled participants received same-day initiation of daily oral PrEP (tenofovir disoproxil fumarate [300 mg] coformulated with emtricitabine [200 mg]). Follow-up visits were scheduled at week 4 and quarterly thereafter. We used logistic regression models to identify factors associated with early loss to follow-up (not returning after enrolment), PrEP adherence (medication possession ratio ≥0·6), and long-term PrEP engagement (attending three or more visits within 52 weeks). This study is registered at the Brazilian Registry of Clinical Trials, U1111-1217-6021.

FINDINGS

From Feb 6, 2018, to June 30, 2021, 9979 participants were screened and 9509 were enrolled (Brazil n=3928, Mexico n=3288, and Peru n=2293). 543 (5·7%) participants were transgender women, 8966 (94·3%) were cisgender men, and 2481 (26·1%) were aged 18-24 years. There were 12 185·25 person-years of follow-up. 795 (8·4%) of 9509 participants had early loss to follow-up, 6477 (68·1%) of 9509 were adherent to PrEP, and 5783 (70·3%) of 8225 had long-term PrEP engagement. Transgender women (adjusted odds ratio 1·60, 95% CI 1·20-2·14), participants aged 18-24 years (1·80, 1·49-2·18), and participants with primary education (2·18, 1·29-3·68) had increased odds of early loss to follow-up. Transgender women (0·56, 0·46-0·70), participants aged 18-24 years (0·52, 0·46-0·58), and those with primary education (0·60, 0·40-0·91) had lower odds of PrEP adherence. Transgender women (0·56, 0·45-0·71), participants aged 18-24 years (0·56, 0·49-0·64), and those with secondary education (0·74, 0·68-0·86) had lower odds of long-term PrEP engagement. HIV incidence was 0·85 per 100 person-years (95% CI 0·70-1·03) and was higher for transgender women, participants from Peru, those aged 18-24 years, Black and mixed-race participants, and participants who were non-adherent to PrEP.

INTERPRETATION

Same-day oral PrEP is feasible for MSM and transgender women in Latin America. Social and structural determinants of HIV vulnerability need to be addressed to fully achieve the benefits of PrEP.

National surveillance of Neisseria gonorrhoeae antimicrobial susceptibility and epidemiological data of gonorrhoea patients across Brazil, 2018–20

Objectives

To (i) describe the nationwide antimicrobial susceptibility of Neisseria gonorrhoeae (NG) isolates cultured across Brazil in 2018–20 and compare it with NG antimicrobial resistance data from 2015–16, and (ii) present epidemiological data of the corresponding gonorrhoea patients in 2018–20.

Methods

Twelve representative sentinel sites cultured NG isolates from men with urethral discharge. Susceptibility to eight antimicrobials was examined using agar dilution method, according to WHO standards. The consenting participants were invited to provide epidemiological data.

Results

In total, 633 NG isolates (one isolate per participant) were analysed, and 449 (70.9%) questionnaires were answered. Heterosexual (68.2%) and homosexual (23.1%) sexual orientations were common, and most prevalent types of unprotected sexual intercourse were vaginal insertive (69.9%), oral giving (56.6%) and anal insertive (47.4%). The levels of in vitro NG resistance to ciprofloxacin, tetracycline, benzylpenicillin, azithromycin, cefixime, gentamicin, spectinomycin and ceftriaxone were 67.3%, 40.0%, 25.7%, 10.6%, 0.3%, 0%, 0% and 0%, respectively. Compliance with the recommended first-line ceftriaxone 500 mg plus azithromycin 1 g therapy was high (90.9%).

Conclusions

Compared with 2015–16, ciprofloxacin resistance has remained high and azithromycin and cefixime resistance rates have increased in Brazil. Resistance remained lacking to ceftriaxone, gentamicin and spectinomycin, which all are gonorrhoea treatment options. The increasing azithromycin resistance in Brazil and internationally may threaten the future use of azithromycin in dual regimens for treatment of gonorrhoea. Consequently, continued and enhanced quality-assured surveillance of gonococcal AMR, and ideally also treatment failures and including WGS, is imperative in Brazil and worldwide.

Effects of PACK guide training on the management of asthma and chronic obstructive pulmonary disease by primary care clinicians: a pragmatic cluster randomised controlled trial in Florianópolis, Brazil

Introduction

The Practical Approach to Care Kit (PACK) guide was localised for Brazil, where primary care doctors and nurses were trained to use it.

Methods

Twenty-four municipal clinics in Florianópolis were randomly allocated to receive outreach training and the guide, and 24 were allocated to receive only the guide. 6666 adult patients with asthma or chronic obstructive pulmonary disease (COPD) were enrolled, and trial outcomes were measured over 12 months, using electronic medical records. The primary outcomes were composite scores of treatment changes and spirometry, and new asthma and COPD diagnosis rates.

Results

Asthma scores in 2437 intervention group participants were higher (74.8%, 20.4% and 4.8% with scores of 0, 1 and 2, respectively) than in 2633 control group participants (80.0%, 16.8% and 3.2%) (OR for higher score 1.32, 95% CI 1.08 to 1.61, p=0.006). Adjusted for asthma scores recorded in each clinic before training started, the OR was 1.24 (95% CI 1.03 to 1.50, p=0.022). COPD scores in 1371 intervention group participants (77.7%, 17.9% and 4.3% with scores of 0, 1 and 2) did not differ from those in 1181 control group participants (80.5%, 15.8% and 3.7%) (OR 1.21, 95% CI 0.94 to 1.55, p=0.142). Rates of new asthma and COPD diagnoses, and hospital admission, and indicators of investigation, diagnosis and treatment of comorbid cardiovascular disease, diabetes and depression, and tobacco cessation did not differ between trial arms.

Conclusion

PACK training increased guideline-based treatment and spirometry for asthma but did not affect COPD or comorbid conditions, or diagnosis rates.

Portuguese (Brazil) Introdução

O guia de Abordagem Prática do Kit de Cuidados em Saúde (PACK) foi adaptado para o sistema de saúde do Brasil; médicos e enfermeiros da atenção primária foram treinados para usá-lo na pratica clínica.

Métodos

Vinte e quatro unidades básicas de saúde (UBS) municipais de Florianópolis foram alocadas aleatoriamente para receber treinamento nas UBS utilizando o guia, e 24 foram alocadas para receber apenas o guia. Foram analisados dados de 6.666 pacientes adultos com asma ou doença pulmonar obstrutiva crônica (DPOC) e os desfechos foram medidos por doze meses, através de registros médicos eletrônicos. Os resultados principais foram escores compostos de mudança no tratamento, realização de espirometria e taxas de novos diagnósticos de asma e DPOC.

Resultados

os escores de asma em 2437 participantes do grupo de intervenção foram maiores (74,8%, 20,4% e 4,8% com escores de 0, 1 e 2 respectivamente) do que em 2633 participantes do grupo controle (80,0%, 16,8% e 3,2%) (odds ratio (OR) para pontuação mais alta 1,32, intervalo de confiança de 95% (IC) 1,08-1,61, p = 0,006). Ajustado para os escores de asma registrados em cada clínica antes do início do treinamento, o OR foi de 1,24 (IC 95% 1,03-1,50, p = 0,022). Os escores da DPOC em 1371 participantes do grupo de intervenção (77,7%, 17,9% e 4,3% com escores de 0, 1 e 2) não diferiram dos de 1181 participantes do grupo controle (80,5%, 15,8% e 3,7%) (OR 1,21 (IC95% 0,94-1,55, p = 0,142) As taxas de novos diagnósticos de asma e DPOC, internação hospitalar e indicadores de diagnóstico e tratamento de co-morbidades cardiovasculares, diabete, depressão e cessação do tabagismo não diferiram entre os grupos experimentais.

Conclusão

O treinamento com PACK aumentou o tratamento baseado em diretrizes e espirometria para asma, mas não afetou as co-morbidades em DPOC ou as taxas de diagnóstico.

Teledermatologia: uma interface entre a atenção primária e atenção especializada em Florianópolis

Introdução: A aplicação do telediagnóstico em dermatologia pode apresentar diversos benefícios como a redução do tempo de espera para consultas com especialistas focais, triagem de doenças graves - principalmente neoplasias - e educação permanente de profissionais. Objetivo: Relatar a experiência da implantação do serviço de teledermatologia no município de Florianópolis - Santa Catarina - e o impacto inicial do processo no acesso e qualificação da assistência aos pacientes com afecções dermatológicas. Métodos: Estudo observacional, transversal e descritivo. Foram utilizados dados do sistema de prontuário eletrônico municipal, base de dados da plataforma Telessaúde-SC e documentos públicos institucionais da Secretaria Municipal de Saúde de Florianópolis entre os anos de 2013 e 2017. Resultados: O serviço de teledermatologia foi implementado no município de Florianópolis em 2015, por meio da adesão ao Sistema Integrado Catarinense de Telemedicina e Telessaúde. O processo de adequação ocorreu por meio da aquisição de equipamentos, adaptações na infraestrutura e capacitações de servidores. No período analisado, verificou-se redução de 52,6% na taxa de encaminhamentos para dermatologia, com expressiva diminuição no tempo de espera para consulta de cerca de 3 anos, em 2013 e 2014, para 20 dias em 2017. Nota-se tendência à qualificação dos encaminhamentos ao serviço, com redução nos laudos emitidos com classificação azul, manejados na APS, e aumento de laudos com classificação amarela, referenciados para dermatologia. Conclusão: A implantação da teledermatologia em Florianópolis representou um grande avanço para o processo de integração entre a Atenção Primária à Saúde e Atenção Especializada, contribuindo para a redução nas filas de espera e na qualificação dos encaminhamentos, com potencial para o aprimoramento da coordenação do cuidado e educação continuada dos profissionais.

Using a mentorship model to localise the Practical Approach to Care Kit (PACK): from South Africa to Brazil

Brazil's Sistema Único de Saúde, or Unified Health System policy, has delivered major improvements in health coverage and outcomes, but challenges remain, including the rise of non-communicable diseases (NCDs) and variations in quality of care across the country. Some of these challenges may be met through the adaptation and implementation of a South African primary care strategy, the Practical Approach to Care Kit (PACK). Developed by the University of Cape Town's Knowledge Translation Unit (KTU), PACK is intended for in-country adaptation by employing a mentorship model. Using this approach, the PACK Adult guide and training materials were localised for use in Florianópolis, Santa Catarina, Brazil, as part of an initiative to reform primary care, expand care for NCDs and make services more accessible and equitable. The value of the collaboration between the KTU and Florianópolis municipality is the transfer of skills and avoidance of duplication of effort involved in de-novo guide development, while ensuring that materials are locally acceptable and applicable. The collaboration has informed the development of the KTU's PACK mentorship package and led to a relationship between the groups of developers, ensuring ongoing learning and research, with the potential of assisting the further scale-up of PACK in Brazil.

Integrating primary care of chronic respiratory disease, cardiovascular disease and diabetes in Brazil: Practical Approach to Care Kit (PACK Brazil): study protocol for randomised controlled trials

BACKGROUND

Multimorbidity is increasing common in Brazilian adults. Comorbid chronic lung disease, cardiovascular disease and diabetes are often inaccurately diagnosed or ineffectively treated. The Global Alliance against Chronic Respiratory Diseases (GARD) aims to strengthen health systems to prevent and control non-communicable diseases through primary health care. The Practical Approach to Care Kit (PACK Adult) is a clinical decision support tool that provides evidence-supported algorithmic guidelines for screening, diagnosis and treatment of chronic diseases, and is widely used in South Africa. It was adapted for Brazil by family physicians in the Florianopolis City Health Department, which trains clinic doctors and nurses to use it.

METHODS

Effectiveness of PACK Adult training will be evaluated in two pragmatic cluster randomised trials, one enrolling adults with chronic lower respiratory diseases and the other enrolling adults with cardiovascular disease or diabetes. Forty-eight municipal clinics in Florianopolis were randomly allocated to intervention or control arms. In intervention arm clinics, doctors and nurses will receive educational outreach training and the PACK Adult clinical decision support tool. In control arm clinics, doctors and nurses will receive only the tool. Trial outcomes will be measured using patients' electronic medical records during 12 months after completion of basic training. Primary outcomes for the respiratory trial are appropriate prescribing, spirometry and diagnosis rates. Primary outcomes for the cardiovascular trial are testing for cardiovascular risk and diabetes, and systolic blood pressure. Educational outreach to primary care professionals could improve respiratory, cardiovascular and diabetes care in Brazil.
