dc.description.abstract | Background: Different progressions or prognoses of chronic obstructive pulmonary disease (COPD) have been reported according to structural abnormalities based on chest computed tomography (CT). This study aimed to investigate whether different structural abnormalities independently affect annual lung function changes and clinical prognosis in patients with COPD. Methods: This longitudinal multicenter observational study was conducted using the KOCOSS cohort (NCT02800499) database in Korea from January 2012 to December 2019. For COPD patients with chest CT findings at baseline enrolment and longitudinal spirometric data, annual forced expiratory volume in 1 s (FEV 1 ) decline rate (mL/year) and clinical outcomes were compared according to structural abnormalities, including emphysema, bronchiectasis (BE), and tuberculosis -destroyed lung (TDL). We estimated the adjusted annual FEV 1 changes using a mixed -effect linear regression model. Results: Among the enrolled 237 patients, 152 showed structural abnormalities. Emphysema, BE, and TDL were observed in 119 (78.3%), 28 (18.4%), and 27 (17.8%) patients, respectively. The annual decline in FEV 1 was faster in COPD patients with structural abnormalities than those without (8 = -70.6 mL/year, P -value = 0.039). BE/TDL-dominant or emphysema -dominant structural abnormality contributed to an accelerated annual FEV 1 decline compared to no structural abnormality (BE/TDL-dominant, 8 = -103.7 mL/year, P -value = 0.043; emphysemadominant, 8 = -84.1 mL/year, P -value = 0.018). Structural abnormalities made no significant differences in acute exacerbation rate and mortality.<br /> Conclusion: The lung function decline rate in COPD differed according to structural abnormalities on CT. These findings may suggest that more focus should be placed on earlier intervention or regular follow-up with spirometry in COPD patients with BE or TDL on chest CT. | - |
