BACKGROUND
Information on non-tuberculosis mycobacterial (NTM) diseases remains limited in Singapore and other Southeast Asian countries. This study aimed to delineate epidemiological and clinical features of pulmonary NTM disease.
METHODS
A retrospective review was performed on all NTM isolates identified in Singapore General Hospital from 2012 to 2016 using the 2007 ATS/IDSA diagnostic criteria.
RESULTS
A total of 2026 NTM isolates from 852 patients were identified. M. abscessus-chelonae group (1010, 49.9%) was the most commonly isolated and implicated in pulmonary NTM disease. Pulmonary cases (352, 76%) had the highest prevalence among patients diagnosed with NTM diseases (465/852, 54.6%) with no gender difference. Male patients were older (68.5 years, P = 0.014) with a higher incidence of chronic obstructive pulmonary disease (COPD) (23.6%, P < 0.001) and recurrent cough with phlegm production (51.6%, P = 0.035). In contrast, more female patients had bronchiectasis (50%, P < 0.001) and haemoptysis (37.6%, P = 0.042). Age and COPD were associated with multiple NTM species isolation per patient.
CONCLUSIONS
M. abscessus-chelonae group was the commonest NTM species isolated in Singapore. Pulmonary NTM infection has the highest frequency with male and female patients associated with a higher incidence of COPD and bronchiectasis respectively. Age and COPD were associated with multiple NTM species isolation per patient.
背景
非结核分枝杆菌（NTM）疾病的信息在新加坡和其他东南亚国家仍然有限。本研究旨在描绘肺 NTM 疾病的流行病学和临床特征。
方法
对 2012 年至 2016 年期间在新加坡总医院鉴定的所有 NTM 分离株，使用 2007 年 ATS/IDSA 诊断标准进行回顾性分析。
结果
共鉴定出 852 例患者的 2026 株 NTM 分离株。脓肿分枝杆菌-chelonae 组（1010 株，占 49.9%）是最常见的分离株，与肺 NTM 疾病有关。在诊断为 NTM 疾病的患者（465/852，54.6%）中，肺病例（352 例，占 76%）患病率最高，且无性别差异。男性患者年龄较大（68.5 岁，P=0.014），慢性阻塞性肺疾病（COPD）发病率较高（23.6%，P<0.001），反复咳嗽并伴有咳痰（51.6%，P=0.035）。相比之下，更多的女性患者患有支气管扩张症（50%，P<0.001）和咯血（37.6%，P=0.042）。年龄和 COPD 与每位患者分离出多种 NTM 物种相关。
结论
脓肿分枝杆菌-chelonae 组是新加坡最常见的 NTM 物种。肺 NTM 感染频率最高，男性和女性患者分别与 COPD 和支气管扩张症的发病率较高有关。年龄和 COPD 与每位患者分离出多种 NTM 物种相关。
