Objective By analyzing the clinical characteristics and related factors of treatment outcomes in patients with nontuberculous mycobacterial pulmonary disease(NTM-PD)in Taizhou,this study provided reference for the management,diagnosis and treatment of NTM-PD.Methods Clinical characteristics of 167 patients with NTM-PD isolated in Taizhou Hospital of Zhejiang Province from January 2016 to December 2021 were retrospectively analyzed.The differences in clinical characteristics were compared between cured group and failed group of 83 cases with Mycobacterium avium complex pulmonary disease(MAC-PD).Results MAC-PD was the most common species among the 167 cases of NTM-PD,accounting for 94.6％,88 patients were treated.The cure rate was 47.7％.Compared with cured group,the patients in failed group had statistical differences in body mass index(BMI)≤ 18.5kg/m2,acid-fast bacilli smear-positive,combined with previous pulmonary tuberculosis,imaging with fibrous-cavernous type and unstandardized medication(P＜0.05).Conclusion MAC-PD is the most common among NTM-PD patients in Taizhou.BMI ≤ 18.5kg/m2,acid-fast bacilli smear-positive,combined with previous pulmonary tuberculosis,imaging with fibrous-cavernous type and unstandardized medication of MAC-PD were more difficult to treat.
