The aim of this study was to describe the frequency of nontuberculous mycobacteria (NTM) isolation and their related outcomes among pediatric patients of a Brazilian university hospital from 2012 to 2019. NTM were identified in different clinical samples by microbiological culture and molecular-based methods. NTM were isolated from 14 patients, out of whom four (27%) were infected and were treated accordingly. Two were infected with Mycobacterium avium complex (MAC), two with M. abscessus complex (MABSC) and one with M. intracellulare. Two patients had cystic fibrosis-related lung disease and improved after successful NTM eradication. One patient was HIV-positive and died. One patient had severe combined immunodeficiency (SCID)-related pneumonia and is currently being followed-up. We conclude that NTM frequency in our center was low among pediatric patients. Whether this is inherent to Brazilian patients, due to the broad coverage of the Bacille Calmette-Guérin (BCG) vaccine in Brazil, or a result of underdiagnosis remains to be elucidated.
本研究旨在描述 2012 年至 2019 年巴西一家大学医院儿科患者中非结核分枝杆菌（NTM）分离的频率及其相关结果。通过微生物培养和基于分子的方法从不同的临床标本中鉴定出 NTM。从 14 名患者中分离出 NTM，其中 4 名（27%）感染并进行了相应治疗。2 名感染鸟分枝杆菌复合群（MAC），2 名感染脓肿分枝杆菌复合群（MABSC），1 名感染胞内分枝杆菌。2 名患者患有囊性纤维化相关肺病，在成功清除 NTM 后得到改善。1 名患者 HIV 阳性并死亡。1 名患者患有严重联合免疫缺陷（SCID）相关肺炎，目前正在接受随访。我们得出结论，本中心儿科患者中 NTM 的频率较低。这是巴西患者固有的，还是由于巴西卡介苗（BCG）疫苗的广泛覆盖，或者是由于诊断不足，仍有待阐明。
