Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In this study, we will collect data of participants about demographic ,co-morbidities ,spirometry, mMRC score ,exacerbation history, QOL-B questionnaire, aetiology, spirometry , HRCT(or CT) scan ,results of microbiology samples and treatments, collect three consecutive sputum(or induced sputum) samples to smear, bacteria culture, acid-fast stain, mycobacterium cultivation and identification, drug susceptibility testing of nontuberculous mycobacteria.To estimate the prevalance of non-tuberculous mycobacterial(NTM) infections in Middle-aged and old women patients with bronchiectasis in northern China. To analyze clinical manifestations and microbiological characteristics of patients with bronchiectasis comorbid NTM infections By 16SRNA and gene sequencing.
In addition, A cross-sectional investigation about lung function and clinical data will be done among patients who have confirmed bronchiectasis with NTM from February 2017 to December 2020.
