Maiga et al.’s article, “ Failure to Recognize Nontuberculous Mycobacteria Leads to Misdiagnosis of Chronic Pulmonary Tuberculosis (2012)” re-evaluates sputum specimens among newly diagnosed TB patients through sputum microscopy, culture, and Mycobacterium tuberculosis drug susceptibility tests. The author utilizes data collected from 142 patients showed the presence of NTM in patients with chronic TB led to a significant impact on clinical management because among the chronic TB cases (61), NTM infection was seen in 11 of the cases and all were receiving or were “clinically empiric candidates” for MDR-TB treatment. The authors utilize these results in order to exhibit the issue with misdiagnosis of NTM as TB, as the MDR-TB treatment is ineffective for treatment of NTM and also expensive, leading to potential financial hardship. The authors’ claim in this article is very relevant to global health as misdiagnoses can often lead to ineffective treatment, and it is extremely interesting that the issue of economic hardship due to unnecessary financial burden is brought up. The findings of this article are relevant to the contribution planned as they show the role of NTM in causing lung disease, however more pertinent to this contribution, this article highlights the necessity to improve management of TB in TB-endemic environments in order to prevent misdiagnosis and inappropriate treatment of MDR cases.
