Abstract:

Objective: To understand the characteristics of nontuberculous mycobacteria (NTM) pulmonary disease, and provide evidence for clinical diagnosis and treatment of NTM pulmonary disease. Methods: The clinical data of 93 patients with NTM pulmonary disease admitted to Beijing Chest Hospital affiliated to Capital Medical University between January 2018 and December 2019 were analyzed retrospectively. Treatment effectivenesses were compared for different treatment. Results: Among 93 patients with NTM pulmonary disease, there were 49 cases infected with Mycobacterium intracellular, 28 cases with Mycobacterium abscesses, 4 cases with Mycobacterium avium, 4 cases with Mycobacterium kansasii, 3 cases with Mycobacterium xenopi, 2 case co-infected with Mycobacterium abscesses and Mycobacterium intracellular, one case with Mycobacterium gordonii, Mycobacterium fortuitum or Mycobacterium stutzeri each. 61 patients (65.59%) had received antituberculosis treatment before the diagnosis of NTM pulmonary disease. 90 (96.77%) patients had complications, of which 52 (57.78%) patients had bronchiectasis, followed by 12 (13.33%) patients with chronic obstructive pulmonary disease (COPD). 83 cases (89.25%) received anti-NTM treatment, and 47 cases (56.63%) completed the course of treatment among whom the success rate of the treatment of pulmonary disease with Mycobacterium avium complex was 51.85% (14/27) while the treatment success rate of Mycobacterium abscesses pulmonary disease was 76.92% (10/13). 48 cases (57.83%) had adverse drug reactions of different degrees during the treatment, and 15 cases (18.07%) discontinued the treatment. 16 patients (19.28%) were lost to follow-up. Conclusion: Mycobacterium intracellular lung disease is the most common NTM pulmonary disease. Most patients were complicated with bronchiectasis, COPD and other basic lung diseases. The clinical characteristics of NTM pulmonary disease and pulmonary tuberculosis are similar, which are easily misdiagnosed as pulmonary tuberculosis. The cure rate of NTM pulmonary disease is low, and the rate of treatment interruption and loss to follow-up is high.
