Prognostic value of bronchiectasis in patients with moderate-to-severe chronic obstructive pulmonary disease.

Rationale: The prevalence of bronchiectasis is high in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) and it has been associated with exacerbations and bacterial colonization. These have demonstrated some degree of prognostic value in patients with COPD but no information about the relationship between bronchiectasis and mortality in patients with COPD is currently available.

Objectives: To assess the prognostic value of bronchiectasis in patients with moderate-to-severe COPD.

Factors associated with bronchiectasis in patients with COPD.

Background: Previous studies have shown a high prevalence of bronchiectasis in patients with moderate to severe COPD. However, the factors associated with bronchiectasis remain unknown in these patients. The objective of this study is to identify the factors associated with bronchiectasis in patients with moderate to severe COPD.
