The study aims to investigate the clinical, laboratory, and epidemiological aspects of patients with NTM isolation at an infectious diseases reference hospital, and to identify factors associated with mortality. Methods This was an observational study in which clinical, epidemiological, and laboratory aspects were evaluated in patients with NTM isolated at care in Hospital São José, located in Northeastern Brazil, from 2005 to 2016. The records of the reference laboratory for NTM isolates were searched from the culture results of patients. Afterward, the medical records of the patients were reviewed. The analytical assessment was conducted by the Mann-Whitney and Fisher's exact test. The adopted level of significance was 5%. Results A total of 69 patients were described, with a predominance of males (73.9%). The main clinical forms identified were pulmonary (60.9%) and disseminated (27.5%). The most frequently NTM identified were Mycobacterium avium (24.6%) and Mycobacterium fortuitum (10.1%). Forty-eight (69.6%) patients had HIV infection. The mortality was 24.6%, and the risk factors for deaths identified were origin from outside the metropolitan region; weight loss; HIV infection; anemia; hyperbilirubinemia; increased serum glutamic-oxaloacetic transaminase, alkaline phosphatase, lactate dehydrogenase; and impaired renal function. Among the patients with HIV, the main changes related to death were lower counts of CD4+ and CD8+ T lymphocytes. Conclusion Maintaining constant vigilance regarding the possibility of NTM infection is required, namely in patients co-infected with HIV/AIDS.Background Mycobacteroides abscessus complex (MABC) exhibits smooth morphotypes, expressing glycopeptidolipid (GPL), and rough morphotypes, expressing diminished GPL, on th
