AI Article Synopsis
- The study investigates how chronic sputum (CS) symptoms impact health-related quality of life (HRQOL) in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD) for the first time.
- Among 99 patients, 71 were identified with CS, showing they had worse pulmonary function and more severe disease as indicated by radiological evaluations.
- The analysis revealed that CS significantly correlated with lower mental health scores in HRQOL assessments, highlighting its detrimental effect on patients' overall well-being.
Article Abstract
Background: The effect of chronic sputum (CS) symptoms on health-related quality of life (HRQOL) in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD) has not been studied. The aim of this study was to clarify the differences in the clinical characteristics of NTM-PD patients with and without CS and to investigate the effect of CS on HRQOL.
Methods: This cross-sectional study included patients with NTM-PD who were prescribed pulmonary rehabilitation at the Fukujuji Hospital from March 2016 to June 2019. HRQOL was evaluated using the MOS 36-Item Short-Form Health Survey (SF-36).
Results: Of the 99 subjects studied, 71 had CS (CS+) (71.7%), and 28 (28.3%) did not have CS (CS-). Patients in the CS + group had a lower body mass index, forced vital capacity percent predicted, and forced expiratory volume in 1 s percent predicted. Regarding the radiological evaluation, the proportion of patients with the fibrocavitary form and the radiological score were significantly higher in the CS + group. The mental component summary (MCS) score of the SF-36 were significantly lower in the CS + group. Multiple regression analysis showed that the presence of CS was independently associated with a lower MCS score of the SF-36.
Conclusions: NTM-PD patients with CS had more severe disease, with reduced pulmonary function and severe radiological findings. CS was shown to independently affect HRQOL, especially mental status.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated chronic fibro-inflammatory condition, that can involve multiple systems. Immunoglobulin G4-related respiratory disease (IgG4-RRD) is relatively rare, with non-specific clinical symptoms. Hemoptysis is a rare clinical symptom of IgG4-RRD, and cases of massive hemoptysis in adults have not been reported.

Background: Adult people with cystic fibrosis (PwCF) have a higher risk of end-stage kidney disease than the general population. The nature and mechanism of kidney disease in CF are unknown. This study quantifies urinary kidney injury markers and examines the hypothesis that neutrophil activation and lung infection are associated with early kidney injury in CF.

A 57-year-old female presented with a chief complaint of cough, with productive yellow sputum particularly severe in the morning. Bronchoscopy revealed inflammatory changes in both main bronchi, with abundant white purulent secretions and necrotic material adhering to the luminal surface. Histopathological examination showed chronic inflammatory changes in the mucosal tissue, with mild hyperplasia of the local squamous epithelium and evidence of keratinization in the surrounding area, consistent with a diagnosis of tracheal mucosal keratosis.
