RESUMO O tratamento da tuberculose permanece um desafio em função da necessidade de que, em sua abordagem, seja considerado o contexto da saúde do indivíduo e da saúde coletiva. Adicionalmente, as questões sociais e econômicas têm-se mostrado como variáveis a ser consideradas na efetividade do tratamento. Ao revisarmos de forma crítica a literatura científica nacional e internacional sobre o tratamento da tuberculose nos últimos anos, tivemos como objetivos apresentar aos profissionais da área de saúde as recomendações baseadas na realidade brasileira e fornecer os subsídios necessários para a melhor tomada de decisão frente ao paciente com tuberculose, de modo a minimizar a morbidade e interromper a transmissão da doença Em função disso, o TDO é recomendado.

ABSTRACT Tuberculosis treatment remains a challenge due to the need to consider, when approaching it, the context of individual and collective health. In addition, social and economic issues have been shown to be variables that need to be considered when it comes to treatment effectiveness. We conducted a critical review of the national and international literature on the treatment of tuberculosis in recent years with the aims of presenting health care workers with recommendations based on the situation in Brazil and better informing decision-making regarding tuberculosis patients so as to minimize morbidity and interrupt disease transmission.

Rheumatoid arthritis (RA) is an autoimmune disease characterised by the destruction of articular cartilage and bone damage. The chronic treatment of RA patients causes a higher susceptibility to infectious diseases such as tuberculosis (TB); one-third of the world’s population is latently infected (LTBI) with Mycobacterium tuberculosis(Mtb). The tuberculin skin test is used to identify individuals LTBI, but many studies have shown that this test is not suitable for RA patients. The goal of this work was to test the specific cellular immune responses to the Mtb malate synthase (GlcB) and heat shock protein X (HspX) antigens of RA patients and to correlate those responses with LTBI status. The T-helper (Th)1, Th17 and Treg-specific immune responses to the GlcB and HspX Mtb antigens were analysed in RA patients candidates for tumour necrosis factor-α blocker treatment. Our results demonstrated that LTBI RA patients had Th1-specific immune responses to GlcB and HspX. Patients were followed up over two years and 14.3% developed active TB. After the development of active TB, RA patients had increased numbers of Th17 and Treg cells, similar to TB patients. These results demonstrate that a GlcB and HspX antigen assay can be used as a diagnostic test to identify LTBI RA patients.
