Anxiety and depression in COPD patients and correlation with sputum and BAL cytology

Abstract

Background and aims: Anxiety and depression are common in patients with chronic obstructive pulmonary disease (COPD). The degree of lung function may not explain anxiety and depression. The aim of our study was to assess the psychological aspects of COPD, to test the BODE index (a composite score of body mass, obstruction, dyspnea and exercise capacity), and to evaluate the association between atypical cytologic findings of sputum, bronchoalveolar lavage (BAL) and the pyschological components of the disease.
