SUMMARY OBJECTIVE: The growing availability of devices for mobile learning has created new opportunities for teaching. With the development of smartphone apps based on audience response systems, there is a possibility to quickly assess student knowledge. The education of health professionals, including medical students, is an essential strategy for tuberculosis control. In the context of the coronavirus disease 2019 pandemic, audience response systems are very useful as online assessment tools. The aim of this study was to use the audience response systems Socrative to assess medical students during a class on tuberculosis. METHODS: This is a quasi-experimental before-and-after study, with pre- and post-tests carried out through the Socrative app, respectively, before and after a lecture on tuberculosis for medical students. Also, a cross-sectional study was carried out after the course to evaluate the participant's satisfaction through an electronic, structured questionnaire with a Likert-type scale. RESULTS: A total of 126 students were included in the study. The overall mean pre- and post-test scores were 5.98±1.59 and 8.37±1.36, respectively, with a statistically significant difference (p<0.0001). Almost all students were totally satisfied with the use of Socrative on pre- and post-tests. CONCLUSION: This study describes how the use of Socrative in a tuberculosis class was well received by students. In addition, the baseline knowledge on tuberculosis was low in some topics, with some improvement after the lecture. These findings emphasize the need to further improve the students' knowledge on tuberculosis and help instructors customize the lecture based on the gaps identified in the Socrative assessment.

SUMMARY OBJECTIVE: The objective of this study was to estimate the seroprevalence of severe acute respiratory syndrome coronavirus 2 antibodies in patients with tuberculosis. METHODS: This cross-sectional study was conducted at an outpatient tuberculosis clinic in Alvorada, RS, Brazil, with data collection between October and December 2020. Outpatients aged>18 years with active pulmonary tuberculosis, no prior history of coronavirus disease 2019, and no suspected coronavirus disease 2019 were included in the study. Whole blood samples were collected to perform the severe acute respiratory syndrome coronavirus 2 antibodies test. RESULTS: During the study period, 52 patients met the inclusion and were included in the analysis. Severe acute respiratory syndrome coronavirus 2 antibodies were positive in 16 (30.8%) patients. Male sex was more frequent among patients with negative severe acute respiratory syndrome coronavirus 2 antibodies than in patients with positive severe acute respiratory syndrome coronavirus 2 antibodies (86.1 vs. 56.3%, p=0.031). Contact with coronavirus disease 2019 case was more common in patients with positive severe acute respiratory syndrome coronavirus 2 antibodies compared with patients with negative severe acute respiratory syndrome coronavirus 2 antibodies (87.5 vs. 8.3%, p<0.0001). In a multivariate analysis, in a model including the variables such as male sex and contact with coronavirus disease 2019 case, only contact with coronavirus disease 2019 was independently associated with positive severe acute respiratory syndrome coronavirus 2 antibodies (OR 77.0, 95%CI 11.5-512.4, p<0.0001). CONCLUSION: This study revealed a seroprevalence of 30.8% severe acute respiratory syndrome coronavirus 2 among patients with tuberculosis.

ABSTRACT Vulnerable populations, such as migrants and refugees, have an increased risk of tuberculosis disease, especially in the first years after arrival in the host country. The presence of migrants and refugees in Brazil exponentially grew over the period between 2011 and 2020, and approximately 1.3 million migrants from the Global South were estimated to be residing in Brazil, most of whom from Venezuela and Haiti. Tuberculosis control programs for migrants can be divided into pre- and post-migration screening strategies. Pre-migration screening aims to identify cases of tuberculosis infection (TBI) and can be carried out in the country of origin (pre-entry) or in the destination country (at entry). Pre-migration screening can also detect migrants at an increased risk of developing tuberculosis in the future. High-risk migrants are then followed up in post-migration screening. In Brazil, migrants are considered a priority group for the active search for tuberculosis cases. However, there is no recommendation or plan regarding screening for TBI in migrants and refugees. Ensuring prevention, diagnosis, and treatment for TBI and tuberculosis disease in migrant populations is an important aspect of tuberculosis control and elimination. In this review article, we address epidemiological aspects and access to health care for migrants in Brazil. In addition, the migration medical screening for tuberculosis was reviewed.
RESUMO Populações vulneráveis, como imigrantes e refugiados, apresentam maior risco de tuberculose doença, especialmente nos primeiros anos após a chegada ao país de acolhimento. A presença de imigrantes e refugiados no Brasil cresceu exponencialmente no período entre 2011 e 2020, sendo estimado que aproximadamente 1,3 milhão de imigrantes do Sul Global residiam no Brasil, a maioria proveniente da Venezuela e do Haiti. Os programas de controle da tuberculose para imigrantes podem ser divididos em estratégias de triagem pré- e pós-migração. A triagem pré-migração visa identificar casos de tuberculose infecção (TBI) e pode ser realizada no país de origem (pré-entrada) ou no país de destino (no momento da entrada). A triagem pré-migração também pode detectar imigrantes com maior risco de desenvolver tuberculose no futuro. Os imigrantes de alto risco são então acompanhados na triagem pós-migração. No Brasil, os imigrantes são considerados um grupo prioritário para a busca ativa de casos de tuberculose. No entanto, não há recomendação ou plano sobre triagem para TBI em imigrantes e refugiados. Garantir a prevenção, o diagnóstico e o tratamento da TBI e da tuberculose doença em populações imigrantes é um aspecto importante do controle e eliminação da tuberculose. Neste artigo de revisão, abordamos aspectos epidemiológicos e acesso à saúde para imigrantes no Brasil. Além disso, revisou-se a triagem médica de imigrantes para tuberculose.

ABSTRACT Historically, all efforts against tuberculosis were focused on rapid diagnosis and effective treatment to break the chain of transmission of Mycobacterium tuberculosis. However, in the last few years, more and more evidence has been found on the dramatic consequences of the condition defined as post-tuberculosis lung disease (PTLD). Approximately one third of patients surviving pulmonary tuberculosis face considerable ongoing morbidities, including respiratory impairment, psychosocial challenges, and reduced health-related quality of life after treatment completion. Given the important global and local burden of tuberculosis, as well as the estimated burden of PTLD, the development of a consensus document by a Brazilian scientific society-Sociedade Brasileira de Pneumologia e Tisiologia (SBPT)-was considered urgent for the prevention and management of this condition in order to allocate resources to and within tuberculosis services appropriately and serve as a guide for health care professionals. A team of eleven pulmonologists and one methodologist was created by the SBPT to review the current evidence on PTLD and develop recommendations adapted to the Brazilian context. The expert panel selected the topics on the basis of current evidence and international guidelines. During the first phase, three panel members drafted the recommendations, which were divided into three sections: definition and prevalence of PTLD, assessment of PTLD, and management of PTLD. In the second phase, all panel members reviewed, discussed, and revised the recommendations until a consensus was reached. The document was formally approved by the SBPT in a special session organized during the 2023 SBPT Annual Conference.
RESUMO Historicamente, todos os esforços contra a tuberculose concentraram-se no diagnóstico rápido e no tratamento efetivo para quebrar a cadeia de transmissão do Mycobacterium tuberculosis. No entanto, nos últimos anos, têm sido encontradas mais e mais evidências sobre as dramáticas consequências da condição definida como doença pulmonar pós-tuberculose (DPPT). Aproximadamente um terço dos pacientes que sobrevivem à tuberculose pulmonar enfrenta morbidades consideráveis e persistentes, incluindo comprometimento respiratório, desafios psicossociais e redução da qualidade de vida relacionada à saúde após o término do tratamento. Diante da importante carga global e local da tuberculose, bem como da carga estimada da DPPT, considerou-se urgente o desenvolvimento de um documento de consenso por uma sociedade científica brasileira - a Sociedade Brasileira de Pneumologia e Tisiologia (SBPT) - para a prevenção e manejo dessa condição, a fim de alocar recursos de forma adequada para e nos serviços de tuberculose e servir de guia para os profissionais de saúde. Uma equipe de onze pneumologistas e um metodologista foi criada pela SBPT para revisar as evidências atuais sobre a DPPT e desenvolver recomendações adaptadas ao contexto brasileiro. O painel de especialistas selecionou os temas com base nas evidências atuais e diretrizes internacionais. Durante a primeira fase, três membros do painel redigiram as recomendações, que foram divididas em três seções: definição e prevalência de DPPT, avaliação da DPPT e manejo da DPPT. Na segunda fase, todos os membros do painel analisaram, discutiram e revisaram as recomendações até chegar a um consenso. O documento foi aprovado formalmente pela SBPT em sessão especial organizada durante o Congresso Anual da SBPT de 2023.

SUMMARY OBJECTIVES: In tuberculosis treatment, corticosteroids are used as adjuvants, especially in meningeal/pericardial tuberculosis. In other forms of the disease, especially in severe tuberculosis requiring mechanical ventilation, its use is controversial. The aim of the present study is to assess whether the use of corticosteroids in the treatment of pulmonary tuberculosis patients in mechanical ventilation is associated with in-hospital mortality. METHODS: This is a retrospective cohort study. Tuberculosis patients >18 years requiring mechanical ventilation, admitted to the emergency department or intensive care unit, were included. Data on corticosteroid use and mortality were collected. RESULTS: In total, 467 patients were included in the analysis; 399 used corticosteroids and 68 were noncorticosteroid users. The mortality rate was higher among corticosteroid users (59.9%) than in noncorticosteroid users (41.2%) (p=0.010). The total dose of corticosteroid in prednisone equivalents was not different between survivors and nonsurvivors (median [interquartile range]: 80 mg [5-56.6 mg] vs. 80 mg [50-135 mg]; p=0.881). CONCLUSIONS: Tuberculosis patients in mechanical ventilation who used corticosteroids had a higher mortality rate than those who did not use corticosteroids. The role of corticosteroids in pulmonary tuberculosis, especially in critically ill patients, remains unclear and needs further evaluation in prospective studies.

ABSTRACT The objective of this study was to describe country-specific lockdown measures and tuberculosis indicators collected during the first year of the COVID-19 pandemic. Data on lockdown/social restrictions (compulsory face masks and hand hygiene; international and local travel restrictions; restrictions to family visits, and school closures) were collected from 24 countries spanning five continents. The majority of the countries implemented multiple lockdowns with partial or full reopening. There was an overall decrease in active tuberculosis, drug-resistant tuberculosis, and latent tuberculosis cases. Although national lockdowns were effective in containing COVID-19 cases, several indicators of tuberculosis were affected during the pandemic.
RESUMO O objetivo deste estudo foi descrever as medidas de confinamento específicas de cada país e os indicadores de tuberculose coletados durante o primeiro ano da pandemia de COVID-19. Dados referentes a confinamento/restrições sociais (uso obrigatório de máscaras faciais e higiene obrigatória das mãos; restrições a viagens internacionais e locais; restrições a visitas familiares e fechamento das escolas) foram coletados de 24 países em cinco continentes. A maioria dos países implantou múltiplos confinamentos, com reabertura parcial ou total. Houve uma redução geral dos casos de tuberculose ativa, tuberculose resistente e tuberculose latente. Embora os confinamentos nacionais tenham sido eficazes na contenção dos casos de COVID-19, vários indicadores de tuberculose foram afetados durante a pandemia.

ABSTRACT Objective: To evaluate lung function in a cohort of patients with a history of pulmonary tuberculosis in Brazil, as well as to evaluate the decline in lung function over time and compare it with that observed in similar cohorts in Mexico and Italy. Methods: The three cohorts were compared in terms of age, smoking status, pulmonary function test results, six-minute walk test results, and arterial blood gas results. In the Brazilian cohort, pulmonary function test results, six-minute walk test results, and arterial blood gas results right after the end of tuberculosis treatment were compared with those obtained at the end of the follow-up period. Results: The three cohorts were very different regarding pulmonary function test results. The most common ventilatory patterns in the Brazilian, Italian, and Mexican cohorts were an obstructive pattern, a mixed pattern, and a normal pattern (in 58 patients [50.9%], in 18 patients [41.9%], and in 26 patients [44.1%], respectively). Only 2 multidrug-resistant tuberculosis cases were included in the Brazilian cohort, whereas, in the Mexican cohort, 27 cases were included (45.8%). Mean PaO2 and mean SaO2 were lower in the Mexican cohort than in the Brazilian cohort (p < 0.0001 and p < 0.002 for PaO2 and SaO2, respectively). In the Brazilian cohort, almost all functional parameters deteriorated over time. Conclusions: This study reinforces the importance of early and effective treatment of drug-susceptible tuberculosis patients, because multidrug-resistant tuberculosis increases lung damage. When patients complete their tuberculosis treatment, they should be evaluated as early as possible, and, if post-tuberculosis lung disease is diagnosed, they should be managed and offered pulmonary rehabilitation because there is evidence that it is effective in these patients.
RESUMO Objetivo: Avaliar a função pulmonar em uma coorte de pacientes com história de tuberculose pulmonar no Brasil, bem como avaliar o declínio da função pulmonar ao longo do tempo e compará-lo com o observado em coortes semelhantes no México e Itália. Métodos: As três coortes foram comparadas quanto à idade, tabagismo, testes de função pulmonar, teste de caminhada de seis minutos e gasometria arterial. Na coorte brasileira, os resultados dos testes de função pulmonar, do teste de caminhada de seis minutos e da gasometria arterial logo após o término do tratamento da tuberculose foram comparados com os obtidos no fim do período de acompanhamento. Resultados: As três coortes foram muito diferentes quanto aos resultados dos testes de função pulmonar. Os padrões ventilatórios mais comuns nas coortes brasileira, italiana e mexicana foram o padrão obstrutivo, o padrão misto e o padrão normal [em 58 pacientes (50,9%), em 18 pacientes (41,9%) e em 26 pacientes (44,1%), respectivamente]. Apenas 2 casos de tuberculose multirresistente foram incluídos na coorte brasileira, ao passo que na coorte mexicana foram incluídos 27 casos (45,8%). As médias da PaO2 e SaO2 foram mais baixas na coorte mexicana do que na brasileira (p < 0,0001 e p < 0,002 para PaO2 e SaO2, respectivamente). Na coorte brasileira, quase todos os parâmetros funcionais se deterioraram ao longo do tempo. Conclusões: Este estudo reforça a importância do tratamento precoce e eficaz de pacientes com tuberculose sensível, pois a tuberculose multirresistente aumenta o dano pulmonar. Quando o tratamento da tuberculose é concluído, os pacientes devem ser avaliados o quanto antes e, caso se estabeleça o diagnóstico de sequelas pulmonares da tuberculose, é preciso tratá-los e oferecer-lhes reabilitação pulmonar, pois há evidências de que ela é eficaz nesses pacientes.

ABSTRACT Given the global burden of tuberculosis, shortened treatment regimens with existing or repurposed drugs are needed to contribute to tuberculosis control. The long duration of treatment of drug-susceptible tuberculosis (DS-TB) is associated with nonadherence and loss to follow up, and the treatment success rate of multidrug-resistant tuberculosis (MDR-TB) is low (approximately 50%) with longer regimens. In this review article, we report recent advances and ongoing clinical trials aimed at shortening regimens for DS-TB and MDR-TB. We discuss the role of high-dose rifampin, as well as that of clofazimine and linezolid in regimens for DS-TB. There are at least 5 ongoing clinical trials and 17 observational studies and clinical trials evaluating shorter regimens for DS-TB and MDR-TB, respectively. We also report the results of observational studies and clinical trials evaluating a standardized nine-month moxifloxacin-based regimen for MDR-TB. Further studies, especially randomized clinical trials, are needed to evaluate regimens including newer drugs, drugs proven to be or highly likely to be efficacious, and all-oral drugs in an effort to eliminate the need for injectable drugs.
RESUMO Em virtude da carga global da tuberculose, esquemas mais curtos de tratamento com medicamentos já existentes ou reaproveitados são necessários para contribuir para o controle da doença. A longa duração do tratamento da tuberculose sensível (TBS) está relacionada com não adesão e perda de seguimento, e a taxa de sucesso do tratamento da tuberculose multirresistente (TBMR) é baixa (de aproximadamente 50%) com esquemas mais longos. Neste artigo de revisão, relatamos avanços recentes e ensaios clínicos em andamento cujo objetivo é encurtar os esquemas de tratamento de TBS e TBMR. Discutimos o papel da rifampicina em altas doses, assim como o da clofazimina e linezolida em esquemas de tratamento de TBS. Relatamos também os resultados de estudos observacionais e ensaios clínicos de avaliação de um esquema padronizado de nove meses à base de moxifloxacina para o tratamento de TBMR. Mais estudos, especialmente ensaios clínicos randomizados, são necessários para avaliar esquemas que incluam medicamentos mais novos, medicamentos comprovadamente ou provavelmente eficazes e medicamentos exclusivamente orais na tentativa de dispensar o uso de medicamentos injetáveis.

ABSTRACT Objective: To evaluate the radiological presentation of patients with pulmonary tuberculosis diagnosed in the emergency department and to investigate its association with the time to diagnosis. Methods: This was a prospective observational study involving patients diagnosed with pulmonary tuberculosis in the emergency department of a tertiary university hospital in southern Brazil. Chest X-rays taken on admission were evaluated by a radiologist. The various patterns of radiological findings and locations of the lesions were described. The main study outcome was the total time elapsed between the initial radiological examination and the diagnosis of tuberculosis. Results: A total of 78 patients were included in the study. The median time from chest X-ray to diagnosis was 2 days, early and delayed diagnosis being defined as a time to diagnosis < 2 days and ≥ 2 days, respectively. Sputum smear positivity was associated with early diagnosis (p = 0.005), and positive culture was associated with delayed diagnosis (p = 0.005). Early diagnosis was associated with the presence of sputum (p = 0.03), weight loss (p = 0.047), cavitation (p = 0.001), and consolidation (p = 0.003). Pulmonary cavitation was found to be an independent predictor of early diagnosis (OR = 3.50; p = 0.028). Conclusions: There is a need for tuberculosis-specific protocols in emergency departments, not only to avoid delays in diagnosis and treatment but also to modify the transmission dynamics of the disease.
RESUMO Objetivo: Avaliar a apresentação radiológica de pacientes com tuberculose pulmonar diagnosticada no serviço de emergência e investigar sua associação com o tempo para o diagnóstico. Métodos: Estudo observacional prospectivo envolvendo pacientes diagnosticados com tuberculose pulmonar no serviço de emergência de um hospital universitário terciário no sul do Brasil. As radiografias de tórax realizadas na admissão foram avaliadas por um radiologista. Foram descritos os diferentes padrões de achados radiológicos e as localizações das lesões. O desfecho principal do estudo foi o tempo total decorrido entre o exame radiológico inicial e o diagnóstico de tuberculose. Resultados: Um total de 78 pacientes foi incluído no estudo. A mediana de tempo entre a radiografia de tórax e o diagnóstico foi de 2 dias, sendo os diagnósticos precoce e tardio definidos como tempo para o diagnóstico < 2 dias e ≥ 2 dias, respectivamente. A positividade da baciloscopia de escarro associou-se ao diagnóstico precoce (p = 0,005), e a cultura positiva associou-se ao diagnóstico tardio (p = 0,005). O diagnóstico precoce associou-se à presença de escarro (p = 0,03), perda de peso (p = 0,047), cavitação (p = 0,001) e consolidação (p = 0,003). A cavitação pulmonar foi um preditor independente de diagnóstico precoce (OR = 3,50; p = 0,028). Conclusões: Há necessidade de protocolos específicos para tuberculose nos serviços de emergência, não apenas para evitar atrasos no diagnóstico e no tratamento, mas também para modificar a dinâmica de transmissão da doença.

Introduction: Registries of spondyloarthritis (SpA) patients' follow-up provided evidence that tumor necrosis factor inhibitors (TNFi) increase the incidence of active tuberculosis infection (TB). However, most of these registries are from low burden TB areas. Few studies evaluated the safety of biologic agents in TB endemic areas. This study compares the TB incidence rate (TB IR) in anti-TNF-naïve and anti-TNF-experienced subjects with SpA in a high TB incidence setting.Methods: In this retrospective cohort study, medical records from patients attending a SpA clinic during 13 years (2004 to 2016) in a university hospital were reviewed. The TB IR was calculated and expressed as number of events per 105 patients/year; the incidence rate ratio (IRR) associated with the use of TNFi was calculated.Results: A total of 277 patients, 173 anti-TNF-naïve and 104 anti-TNF-experienced subjects, were evaluated; 35.7% (N = 35) of patients who were prescribed an anti-TNF drug were diagnosed with latent tuberculosis infection (LTBI). Total follow-up time (person-years) was 1667.8 for anti-TNF-naïve and 394.9 for anti-TNF-experienced patients. TB IR (95% CI) was 299.8 (37.4-562.2) for anti-TNF naïve and 1012.9 (25.3-2000.5) for anti-TNF experienced subjects. The IRR associated with the use of TNFi was 10.4 (2.3- 47.9).Conclusions: In this high TB incidence setting, SpA patients exposed to anti-TNF therapy had a higher incidence of TB compared to anti-TNF-naïve subjects, although the TB incidence in the control group was significant.(AU)
