Background: Recently, it has been proposed that different clinical phenotypes can be recognized in patients with chronic obstructive disease (COPD), namely predominant airway disease or parenchymal destructive changes. Objectives: The aim of this prospective multicenter study was to evaluate whether these two phenotypes may influence outcomes following a pulmonary rehabilitation program (PRP). Methods: We have prospectively evaluated 364 consecutive COPD patients (70 +/- 8 years, 76.3% males) admitted to a standard hospital-based PRP in 6 Italian centers. According to their phenotype, the study cohort was divided into two groups: patients with airway obstructive (group 1, n = 208) or parenchymal destructive COPD (group 2, n = 156). Before and after PRP, values of 6-min walking distance, perceived breathlessness (Medical Research Council), health-related quality of life (St. George's Respiratory Questionnaire) and respiratory muscle maximal inspiratory and expiratory pressure) were recorded. Results: PRP resulted in significant improvements in all outcome measures without any significant differences between groups. Conclusions: Our study confirms that COPD patients may benefit from pulmonary rehabilitation independent of their clinical phenotype.
