Abstract:

Objective To analyze the strain distribution and clinical characteristics of non-tuberculous Mycobacterium (NTM) lung disease patients in Tianjin area, and to provide reference for clinical diagnosis and treatment of NTM lung disease in Tianjin area. Methods A total of 106 patients with NTM pulmonary disease were selected. The distribution of NTM bacteria, the distribution of complications and clinical manifestations of patients and the chest imaging manifestations with different NTM bacteria infection were analyzed. Levels of leukocyte, hemoglobin and serum albumin in patients infected with Mycobacterium intracellular, Mycobacterium chelonabscessus and Mycobacterium kansasii were compared. Results Among 106 patients with NTM lung disease, the top three strains were Mycobacterium intracellular (39.62%, 42/106), Mycobacterium kansasii (23.58%, 25/106) and Mycobacterium chelonabscessus (23.58%, 25/106). The main complications were pulmonary tuberculosis, bronchiectasis, chronic obstructive pulmonary disease and diabetes. Cough and expectoration were the most common clinical manifestations (64.15%, 68/106), followed by fever (35.85%, 38/106), shortness of breath (16.98%, 18/106) and hemoptysis (16.04%, 17/106). The imaging features of 100 patients were mainly exudation, cavity and bronchiectasis. The proportion of pleural effusion in Mycobacterium intracellular infection patients was higher than that in Mycobacterium chelonabscessus infection patients and Mycobacterium kansasii infection patients (P<0.05). The proportion of bronchiectasis was lower in Mycobacterium kansasii infection patients than that in Mycobacterium intracellular infection patients and Mycobacterium chelonabscessus infection patients (P<0.01). The hemoglobin level was lower in patients with mycobacterium intracellular infection than that in patients with Mycobacterium chelonabscessus and Mycobacterium kansasii infection (P<0.05). Albumin level was lower than that in patients with Mycobacterium chelonabscessus infection (P<0.05). Conclusion The prevalent strains of NTM pulmonary disease patients in Tianjin are mainly Mycobacterium intracellular, kansasii and chelonabscessus. Clinical manifestations are mainly cough, expectoration and fever. The imaging manifestations are mainly exudation, cavity and bronchiectasis.
