Objectives

Narrative objectives1

Focusing on the cough/sputum symptoms of COPD patients and mucus plugs on images, COPD patients will be divided into a group with wet cough, a group with dry cough, and a group with no cough, and the occurrence of exacerbations or deaths will be prospectively observed.

Basic objectives2

Others

Basic objectives -Others

To investigate the relationship between cough/sputum symptoms and mucus plugs on imaging in COPD patients.

Developmental phase



Assessment

Primary outcomes

To compare the frequency of COPD exacerbations and deaths among patients with wet cough, those with dry cough, and those without cough.

Key secondary outcomes

We will compare chest CT mucus plug scores, emphysema scores, degree of airway wall thickness, frequency of sinusitis, frequency of heart disease, BNP values, peripheral blood eosinophil/neutrophil counts, non-specific IgE, presence or absence of allergen sensitization, serum biomarkers (IL-8, IL-33, etc.), exhaled NO value, and pulmonary function in patients with wet cough, dry cough, and no cough. We will also analyze changes in these clinical indicators and the incidence of COPD exacerbations, hospitalization rates, and mortality rates during the observation period.
In cases who were able to expectorate sputum (mainly the group with wet cough), we will analyze the types of bacterial flora in sputum cultures and the incidence of COPD exacerbations, hospitalization rates, and mortality rates.
In addition, only in cases where testing was possible, we will analyze the relationship between capsaicin cough sensitivity, cell fractions in induced sputum, biomarkers in sputum supernatant (IL-8, IL-33, etc.) and the incidence of COPD exacerbations during the observation period, hospitalization rate, mortality rate, mucus plug score on chest CT, emphysema score, airway wall thickness, presence or absence of allergen sensitization, serum biomarkers (IL-8, IL-33, etc.), exhaled NO value, lung function, etc.
