ABSTRACT The incidence and clinical characteristics of NTM diseases in Brazil remain relatively unknown. The present study describes the diagnosis of NTM isolates, the clinical presentation and treatment outcomes. We analyzed NTM isolates in patients of a tertiary hospital in the Southeast region of Brazil, from January 2008 to July 2019. The ATS/IDSA criteria for diagnosis and treatment of these patients was applied. Mycobacterium kansasii were identified in 13/113 (11.5%) patients. In 59/113 (52.2%) patients who met the ATS criteria for disease, 29/59 (49.1%) received treatment, and 22/29 (75.8%) were cured. The major species identified was M. kansasii. The most frequent symptoms among the treated patients were dyspnea and cough, and the proportion of cured patients was high.

RESUMO Objetivo: Avaliar o impacto do instrumento denominado “Estratificação por Grau de Risco Clínico e de Abandono do Tratamento da Tuberculose” (ERTB) nos desfechos da tuberculose. Métodos: Ensaio clínico pragmático envolvendo pacientes com diagnóstico confirmado de tuberculose atendidos em uma das 152 unidades de atenção primária à saúde na cidade de Belo Horizonte (MG) entre maio de 2016 e abril de 2017. Foram identificadas áreas de cluster para tuberculose, e as unidades e os respectivos pacientes foram divididos em grupos intervenção (uso do instrumento ERTB) e não intervenção. Resultados: A amostra total foi composta por 432 participantes, dos quais 223 e 209 foram alocados nos grupos não intervenção e intervenção, respectivamente. O risco de abandono do tratamento no grupo não intervenção foi significativamente maior do que no grupo intervenção (OR = 15,010; p < 0,001), independentemente do número de fatores de risco identificados. As curvas de Kaplan-Meier mostraram uma razão de risco de 0,0753 (p < 0,001). Conclusões: O instrumento ERTB foi eficaz em reduzir o abandono do tratamento da tuberculose, independentemente do número de fatores de risco identificados. Esse instrumento é rápido e fácil de utilizar e pode ser adaptado a diferentes realidades.

ABSTRACT Objective: Evaluate the impact of the instrument of the “Stratification by Degree of Clinical Severity and Abandonment Risk of Tuberculosis Treatment” (SRTB) on the tuberculosis outcome. Methods: This study was a pragmatic clinical trial involving patients with a confirmed diagnosis of tuberculosis treated at one of the 152 primary health care units in the city of Belo Horizonte, Brazil, between May of 2016 and April of 2017. Cluster areas for tuberculosis were identified, and the units and their respective patients were divided into intervention (use of SRTB) and nonintervention groups. Results: The total sample comprised 432 participants, 223 and 209 of whom being allocated to the nonintervention and intervention groups, respectively. The risk of treatment abandonment in the nonintervention group was significantly higher than was that in the intervention group (OR = 15.010; p < 0.001), regardless of the number of risk factors identified. Kaplan-Meier curves showed a hazard ratio of 0.0753 (p < 0.001). Conclusions: The SRTB instrument was effective in reducing abandonment of tuberculosis treatment, regardless of the number of risk factors for that. This instrument is rapid and easy to use, and can be adapted to different realities. Its application showed characteristics predisposing to a non-adherence to the treatment and established bases to mitigate its impact.

Abstract INTRODUCTION: The concomitant use of antituberculosis and antiretroviral drugs, as well as drugs to treat other diseases, can cause drug-drug interactions. This study aimed to describe potential drug-drug interactions (pDDI) in patients with TB and HIV/AIDS co-infection, as well as to analyze possible associated factors. METHODS: This study was performed in a reference hospital for infectious and contagious diseases in the southeastern region of Brazil and evaluated adult patients co-infected with tuberculosis and HIV/AIDS. A cross-sectional study was conducted in which sociodemographic, clinical, and pharmacotherapeutic characteristics were assessed. The pDDI were identified using the Drug-Reax software. Association analysis was performed using either a chi-squared test or a Fisher’s exact test. Correlation analysis was performed using the Spearman’s coefficient. RESULTS: The study included 81 patients, of whom 77 (95.1%) were exposed to pDDI. The most frequent interactions were between antituberculosis and antiretroviral drugs, which can cause therapeutic ineffectiveness and major adverse reactions. A positive correlation was established between the number of associated diseases, the number of drugs used, and the number of pDDI. An association was identified between contraindicated and moderate pDDI with excessive polypharmacy and hospitalization. CONCLUSIONS: We found a high frequency of pDDI, especially among those hospitalized and those with excessive polypharmacy. These findings highlight the importance of pharmacists in the pharmacotherapeutic monitoring in these patients.

RESUMEN OBJETIVO: Estimar a prevalência do tabagismo e avaliar os fatores a ele associados em pessoas vivendo com HIV (PVHIV). MÉTODOS: Trata-se de estudo transversal de uma coorte prospectiva concorrente com 462 indivíduos em início de terapia antirretroviral atendidos em três serviços de assistência especializada ao HIV/aids em Belo Horizonte entre 2015 e 2017. Os status de tabagismo utilizados foram: fumante atual (FA), ex-fumante (EF) e não fumante (NF). Realizou-se regressão logística multinomial, sendo NF a categoria de referência. RESULTADOS: A maioria dos participantes eram homens (81,4%), jovens (de até 34 anos; 57,2%) e não brancos (75,7%). Do total de indivíduos, 27,7% eram FA, 22,9% EF, e 49,4% NF. A maioria dos tabagistas eram fumantes leves (65,1%), consumiam até 10 cigarros por dia e fumavam havia mais de 10 anos (63,3%), tendo começado em média aos 17,2 anos de idade (DP = 5,1). Na análise multivariada, maiores chances de ser FA se associaram a: ser do sexo feminino, ter até 9 anos de escolaridade, usar ou já ter usado álcool e drogas ilícitas (maconha, cocaína e crack) e apresentar sinais e/ou sintomas de ansiedade ou depressão. Maiores chances de ser EF se associaram a ter até 9 anos de escolaridade e usar ou já ter usado álcool e drogas e ilícitas (maconha e crack). CONCLUSÕES: Os resultados mostram que o tabagismo é altamente prevalente entre PVHIV, indicando a necessidade de os serviços de assistência especializada em HIV priorizarem intervenções a fim de cessá-lo, com abordagem sobre o uso de álcool e drogas ilícitas, especialmente voltadas para pessoas jovens, com baixa escolaridade e com sinais e/ou sintomas de ansiedade ou depressão.

ABSTRACT OBJECTIVE: To estimate the prevalence of smoking and evaluate the factors associated with this outcome in people living with HIV (PLHIV). METHODS: This is a cross-sectional study of a prospective concurrent cohort of 462 individuals initiating antiretroviral therapy at three HIV/AIDS specialized services in Belo Horizonte between 2015 and 2017. The following smoking status were used: current smoker (CS), former smoker (FS) and non-smoker (NS). Multinomial logistic regression was performed with NS as the reference category. RESULTS: Most participants were men (81.4%), young (up to 34 years old; 57.2%) and non-white (75.7%). Of the total number of individuals, 27.7% were CS, 22.9% FS, and 49.4% NS. Most smokers were light smokers (65.1%), consumed up to 10 cigarettes per day and had been smoking for more than 10 years (63.3%), starting on average at 17.2 years of age (SD = 5.1). In the multivariate analysis, higher chances of being CS were associated with: being female, having up to 9 years of schooling, current or prior use of alcohol and illicit drugs (marijuana, cocaine and crack) and presenting signs and/or symptoms of anxiety or depression. Higher chances of being FS were associated with having up to 9 years of schooling and current or prior use of alcohol and illicit drugs (marijuana and crack). CONCLUSIONS: The results show that smoking is highly prevalent among PLHIV, indicating the need for HIV specialized services to prioritize smoking cessation interventions. These interventions should consider the use of alcohol and illicit drugs and be targeted especially to young people, those with low schooling and with signs and/or symptoms of anxiety or depression.

Abstract INTRODUCTION: Rapid and accurate tuberculosis detection is critical for improving patient diagnosis and decreasing tuberculosis transmission. Molecular assays can significantly increase laboratory costs; therefore, the average time and economic impact should be evaluated before implementing a new technology. The aim of this study was to evaluate the cost and average turnaround time of smear microscopy and Xpert assay at a university hospital. METHODS: The turnaround time and cost of the laboratory diagnosis of tuberculosis were calculated based on the mean cost and activity based costing (ABC). RESULTS: The average turnaround time for smear microscopy was 16.6 hours while that for Xpert was 24.1 hours. The Xpert had a mean cost of USD 17.37 with an ABC of USD 10.86, while smear microscopy had a mean cost of USD 13.31 with an ABC of USD 6.01. The sensitivity of smear microscopy was 42.9% and its specificity was 99.1%, while the Xpert assay had a sensitivity of 100% and a specificity of 96.7%. CONCLUSIONS: The Xpert assay has high accuracy; however, the turnaround time and cost of smear microscopy were lower than those of Xpert.

The present study aimed at evaluating its performance in a multicenter study. (2) Methods: To determine its accuracy, the proportion methods in Lowenstein Jensen medium or the BACTECTMMGITTM960 system was used as a gold standard. (3) Results: The study revealed that the respective accuracies of the kit with 190 M. tuberculosis clinical isolates, using the proportion methods in Lowenstein Jensen medium or BACTECTMMGITTM960 system as a gold standard, were 93.9% and 94.6%, 96.9% and 94.6%, 98.0% and 97.8%, and 98.0% and 98.9%, for streptomycin, isoniazid, rifampicin, and ethambutol, respectively. (4) Conclusion: Thus, the kit can rapidly screen resistance to streptomycin, isoniazid, rifampicin, and ethambutol. Additionally, it does not require sophisticated equipment; hence, it can be easily used in the laboratories of low and middle income countries.

Abstract INTRODUCTION: The present study sought to assess the mean and activity based cost (ABC) of the laboratory diagnosis for tuberculosis through the application of conventional and molecular techniques-Xpert®MTB/RIF and Genotype®MTBDRplus-in a tertiary referral hospital in Brazil. METHODS: The mean cost and ABC formed the basis for the cost analysis of the TB laboratory diagnosis. RESULTS: The mean cost and ABC were US$ 4.00 and US$ 3.24, respectively, for a bacilloscopy; US$ 6.73 and US$ 5.27 for a Lowenstein-Jensen (LJ) culture; US$ 105.42 and US$ 76.56 for a drug sensitivity test (DST)-proportions method (PM) in LJ; US$ 148.45 and US$ 136.80 for a DST-BACTECTM MGITTM 960 system; US$ 11.53 and US$ 9.89 for an Xpert®MTB/RIF; and US$ 84.21 and US$ 48.38 for a Genotype®MTBDRplus. CONCLUSIONS: The mean cost and ABC proved to be good decision-making parameters in the diagnosis of TB and MDR-TB. The effective implementation of algorithms will depend on the conditions at each location.

RESUMO Objetivo: Avaliar os fatores de risco de pacientes atendidos em um hospital de referência terciária para o desenvolvimento de tuberculose e tuberculose multirresistente (TBMR). Métodos: Estudo transversal baseado em dados obtidos de pacientes atendidos no Hospital Júlia Kubitschek, na cidade de Belo Horizonte (MG), entre outubro de 2012 e outubro de 2014. As variáveis utilizadas foram agrupadas em características sociodemográficas, comportamentais, clínicas e radiológicas. O desfecho considerado para verificar associações entre tuberculose e variáveis explicativas foi o tratamento prescrito para tuberculose. Para avaliar a associação entre a tuberculose resistente e as mesmas variáveis explicativas considerou-se a mudança de tratamento para TBMR. Resultados: Alcoolismo, padrão radiológico sugestivo de tuberculose, presença de comorbidades e presença de cavitações pulmonares foram fatores associados à tuberculose. A TBMR foi associada a tratamento prévio para tuberculose e presença de cavitações. Conclusões: Apesar dos importantes progressos na luta contra a tuberculose, é necessário um conjunto de ações articuladas que incluam medidas de proteção social e suporte aos pacientes.

ABSTRACT Objective: To evaluate the risk factors for the development of tuberculosis and multidrug-resistant tuberculosis (MDR-TB) in patients treated at a tertiary referral hospital. Methods: This was a cross-sectional study based on data obtained from patients treated at the Júlia Kubitschek Hospital, located in the city of Belo Horizonte, Brazil, between October of 2012 and October of 2014. We evaluated sociodemographic, behavioral, clinical, and radiological variables. The outcome considered to identify associations between tuberculosis and the explanatory variables was the treatment prescribed. To evaluate the associations between MDR-TB and the same explanatory variables, the change in MDR-TB treatment was considered. Results: The factors associated with tuberculosis were alcoholism, comorbidities, pulmonary cavitations, and a radiological pattern suggestive of tuberculosis. Cavitation and previous treatment for tuberculosis were associated with MDR-TB. Conclusions: Despite the significant progress made in the fight against tuberculosis, there is a need for coordinated actions that include social protection measures and patient support.

Abstract INTRODUCTION: Adverse drug reactions can develop when using anti-tuberculosis medication, and the effects of the drugs can also significantly hinder the treatment of patients. METHODS: A cross-sectional survey was conducted in 73 patients using two standardized questionnaires and the World Health Organization Quality of Life-Bref. RESULTS: All patients reported the presence of adverse drug reactions, 71.6% of which are minor and 28.3% both major and minor. The global quality of life analysis showed that patients with tuberculosis have a good average (67.3%). CONCLUSIONS: There is an association between quality of life and adverse drug reaction, educational level, and vulnerability.

RESUMO Objetivo: Determinar a frequência de problemas relacionados ao uso de medicamentos no tratamento de pacientes com tuberculose e HIV/AIDS. Métodos: Os dados foram obtidos por estudo transversal realizado entre setembro de 2015 e dezembro de 2016 em hospital referência em doenças infectocontagiosas de Belo Horizonte (MG), Brasil. As variáveis sociodemográficas, clínicas, comportamentais e farmacoterapêuticas foram avaliadas por questionário semiestruturado. Classificaram-se os problemas relacionados ao uso de medicamento empregando o método Pharmacotherapy Workup de atenção farmacêutica. Os fatores associados aos problemas relacionados ao uso de medicamentos de indicação, efetividade, segurança e adesão foram avaliados pela regressão logística múltipla. Resultados: Foram avaliados 81 pacientes, e 80% apresentaram pelo menos um problema relacionado ao uso de medicamentos, sendo os mais frequentes ligados à problemas relacionados ao uso de medicamentos de indicação e adesão. Os fatores associados aos problemas relacionados ao uso de medicamentos foram idade, estado civil, caso novo, etnia, tempo de diagnóstico do HIV e tempo de tratamento da tuberculose. Conclusão: A frequência de problemas relacionados ao uso de medicamentos em pacientes coinfectados foi alta, e a identificação dos principais problemas relacionados ao uso de medicamentos e dos fatores associados aos mesmos pode direcionar a equipe multiprofissional de saúde, para garantir o uso dos medicamentos mais indicados, efetivos, seguros e convenientes para a condição clínica dos pacientes. Os indivíduos coinfectados com tuberculose e HIV/AIDS maiores de 40 anos possuem maior chance de apresentarem problemas relacionados ao uso de medicamentos durante o tratamento, sendo os mais frequentes os que indicam a necessidade de medicamento para condição de saúde não tratada e não adesão ao tratamento. Pacientes mais idosos, solteiros ou não, que já trataram a tuberculose antes, com menor tempo de tratamento de tuberculose e maior tempo de diagnóstico de HIV/AIDS devem ter atenção especial no acompanhamento por uma equipe multiprofissional de saúde por indicarem maior chance de apresentar Problemas Relacionados ao uso de Medicamentos de não adesão à terapia.

ABSTRACT Objective: To determine the frequency of drug therapy problem in the treatment of patients with tuberculosis and HIV/AIDS. Methods: Data were obtained through a cross-sectional study conducted between September 2015 and December 2016 at a reference hospital in infectious diseases in Belo Horizonte (MG), Brazil. Sociodemographic, clinical, behavioral and pharmacotherapeutic variables were evaluated through a semi-structured questionnaire. Drug-related problems of pharmaceutical care were classified using the Pharmacotherapy Workup method. Factors associated with indication, effectiveness, safety and compliance drug therapy problem were assessed through multiple logistic regression. Results: We evaluated 81 patients, and 80% presented at least one drug therapy problem, with indication and adherence drug therapy problem being the most frequent. The factors associated with drug therapy problem were age, marital status, new case, ethnicity, time of HIV diagnosis and time to treat tuberculosis. Conclusion: The frequency of drug therapy problem in coinfected patients was high and the identification of the main drug therapy problem and associated factors may lead the multiprofessional health team to ensure the use of the most indicated, effective, safe and convenient medicines for the patients clinical condition. Tuberculosis and HIV/AIDS coinfected individuals aged over 40 years are more likely to have drug therapy problems during treatment; in that, the most frequente are those that signal toward need of medication for an untreated health condition and non-compliance to treatment. Thus, older patients, unmarried or married, who have treated tuberculosis before, with a shorter time to tuberculosis treatment and longer time to diagnose HIV/AIDS, should receive special attention and be better followed by a multiprofessional health team because they indicate a higher chance of presenting Problems related to the use of non-adherent drugs.

RESUMO Objetivo: Estimar a prevalência da infecção latente por Mycobacterium tuberculosis (ILTB) em transplantados renais e avaliar as associações sociodemográficas, comportamentais e clínicas com a prova tuberculínica (PT) positiva. Métodos: Estudo transversal, com pacientes com idade ≥ 18 anos, transplantados renais no Centro de Transplante Renal do Hospital das Clínicas da Universidade Federal de Minas Gerais, em Belo Horizonte (MG). Foram incluídos os pacientes submetidos a transplante renal que realizaram a PT no período entre janeiro de 2011 e julho de 2013. Quando o resultado da primeira PT foi negativo, uma segunda PT foi realizada. As análises bivariada e multivariada, por meio de regressão logística, foram utilizadas para determinar os fatores associados com PT positiva. Resultados: A amostra incluiu 216 pacientes. A taxa de prevalência para ILTB foi de 18.5%. Na análise multivariada, história de contato com caso de tuberculose e função do enxerto preservada (taxa de filtração glomerular estimada ≥ 60 ml/min/1,73 m2) foram associadas com PT positiva. O incremento da primeira PT para a segunda PT foi de 5,8%, considerado significante (p = 0,012). Conclusões: A prevalência da ILTB foi baixa nessa amostra de pacientes transplantados renais. A PT deve ser efetuada quando a função do enxerto renal estiver preservada. Uma segunda PT deve ser realizada quando a primeira PT for negativa.

ABSTRACT Objective: To estimate the prevalence of latent Mycobacterium tuberculosis infection (LTBI) in renal transplant recipients and to assess sociodemographic, behavioral, and clinical associations with positive tuberculin skin test (TST) results. Methods: This was a cross-sectional study of patients aged ≥ 18 years who underwent renal transplantation at the Renal Transplant Center of the Federal University of Minas Gerais Hospital das Clínicas, located in the city of Belo Horizonte, Brazil. We included renal transplant recipients who underwent the TST between January 2011 and July 2013. If the result of the first TST was negative, a second TST was administered. Bivariate and multivariate analyses using logistic regression were used to determine factors associated with positive TST results. Results: The sample included 216 patients. The prevalence of LTBI was 18.5%. In the multivariate analysis, history of contact with a tuberculosis case and preserved graft function (estimated glomerular filtration rate ≥ 60 mL/min/1.73 m2) were associated with positive TST results. TST induration increased by 5.8% from the first to the second test, which was considered significant (p = 0.012). Conclusions: The prevalence of LTBI was low in this sample of renal transplant recipients. The TST should be administered if renal graft function is preserved. A second TST should be administered if the first TST is negative.

Abstract DNA genotyping of Mycobacterium tuberculosis has been widely applied in the understanding of disease transmission in many countries. The purpose of this study was to genotype the strains of M. tuberculosis isolated in patients with new tuberculosis (TB) cases in Minas Gerais, as well as to compare the similarity, discriminatory power, and agreement of the clusters between the IS6110 Restriction Fragment Length Polymorfism (RFLP) and 12 loci Variable Number Tandem Repeat - Mycobacterial Interspersed Repetitive Units (MIRU-VNTR) techniques. It was observed that 32% (66/204) of the isolated strains in the RFLP-IS6110 and 50.9% (104/204) of the isolated strains in the MIRU-VNTR presented a similarity of equal to or above 85%. The RFLP-IS6110 and MIRU-VNTR proved to contain a high discriminatory power. The similarity index resulting from the RFLP showed no recent transmission. Good agreement was observed between the techniques when clusters were detected; however, the best epidemiological relationship was found when using the RFLP-IS6110.
