Cohort study 

研究目的:

本研究旨在基于纳米孔靶向测序对疑似非结核分枝杆菌(Nontuberculous mycobacteria, NTM)肺病患者的呼吸道标本进行菌种鉴定,以及预测克拉霉素(clarithromycin, CLR)和阿米卡星(amikacin, AMK)和利福平(rifampicin,RFP)等核心药物的耐药性,以期优化治疗方案,提高治愈率。  

Objectives of Study:

The purpose of this study was to identify bacterial strains in respiratory specimens from patients with suspected nontuberculous mycobacterial lung disease based on nanopore targeted sequencing. As well as predicting resistance to core drugs such as clarithromycin (CLR) and amikacin (AMK) and rifampicin (RFP) in order to optimize the treatment regimen and improve the cure rate.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄≥18周岁,性别不限。 2.符合疑似NTM肺病诊断标准,参考中国《非结核分枝杆菌病诊断与治疗指南2020年版》:①痰液或支气管肺泡灌洗液抗酸杆菌检查阳性而临床表现与肺结核不相符者;②痰或灌洗液标本显微镜检查发现菌体异常的分枝杆菌;③痰或灌洗液标本中分枝杆菌培养阳性,但其菌落形态和生长情况与MTB有异;④痰或灌洗液标本抗酸杆菌检查阳性而MTB分子生物学检查阴性者;⑤接受正规抗结核治疗无效而反复排菌的患者,且肺部病灶以支气管扩张、多发性小结节以及薄壁空洞为主;⑥咳嗽咳痰2周以上、咯血、消瘦、乏力、或盗汗等具有结核病的临床症状,但MTB分子生物学检测和结核菌素皮肤试验或γ-干扰素释放试验或重组结核杆菌融合蛋白等均阴性,影像学疑似NTM肺病;⑦有免疫缺陷但已除外肺结核的肺病患者。 3.支气管镜检查医生评估患者的情况可耐受肺泡灌洗并获取足够的肺泡灌洗液。 4.受试者自愿参加本研究,并签署知情同意书;若受试者无法参与知情过程,则必须由其法定代理人代理参与知情同意过程并签署知情同意书。

Inclusion criteria

1. Age ≥18 years old, gender unlimited. 2. Meet the diagnostic criteria for suspected NTM lung disease, refer to China's "Guidelines for the Diagnosis and Treatment of Nontuberculous Mycobacteriosis 2020 Edition" : ① The sputum or bronchoalveolar lavage fluid is positive for acid-fast bacilli, but the clinical manifestations are inconsistent with tuberculosis; ② Abnormal mycobacteria were found in sputum or lavage fluid samples by microscope examination; ③ The sputum or lavage fluid samples were positive for mycobacterium culture, but the colony morphology and growth were different from MTB. ④ Sputum or lavage fluid samples were positive for acid-fast bacilli but negative for MTB molecular biology; ⑤ Patients who received regular anti-tuberculosis therapy failed and repeated bacterial expulsion, and the lung lesions were mainly bronchiectasis, multiple nodules and parenchyma cavities; Cough cough sputum for more than 2 weeks, hemoptysis, wasting, fatigue, or night sweating have clinical symptoms of tuberculosis, but MTB molecular biological test and tuberculin skin test (TST) or Interferon-Gamma Release Assays (IGRAs) or recombinant tuberculosis fusion protein (ESAT6-CFP10, EC) are negative, imaging suspected NTM lung disease; ⑦ Patients with pulmonary disease who have immune deficiency except tuberculosis. 3. The bronchoscopy physician assesses the patient's condition to tolerate alveolar lavage and obtain sufficient alveolar lavage fluid. 4. Subjects voluntarily participate in this study and sign informed consent; If the subject is unable to participate in the informed consent process, his/her legal representative must participate in the informed consent process and sign the informed consent.

排除标准:

1. 未按预期获得足够的合格支气管肺泡灌洗液标本。 2. 正在抗分枝杆菌治疗的患者。

Exclusion criteria:

1. Not enough qualified bronchoalveolar lavage fluid specimens were obtained as expected. 2. Patients undergoing anti-mycobacterium therapy.
