RESUMO
INTRODUCTION: Home-based pulmonary rehabilitation (PR) has demonstrated its effectiveness amongst patients with chronic obstructive pulmonary disease (COPD) but has never been investigated in severe asthma. METHODS: In a retrospective study, we included 28 patients with severe asthma (61.5⯱â¯16.2 years, FEV1: 51.4⯱â¯17.3%) and 164 matched COPD patients (64.3⯱â¯11.6 years, FEV1: 47.7⯱â¯15.5%) who had completed a home-based PR program and pursued at least 12 months of follow-up. The number of steps performed during a 6-min stepper test (6MST), the Hospital Anxiety and Depression (HAD) scores, and the Visual Simplified Respiratory Questionnaire score (VSRQ) were compared between baseline, the post-PR period (post-PR) and after 12 months of follow-up (M12) within each group. The evolution of the 6MST, HAD and VSRQ values between baseline, post-PR and M12 was compared between severe asthma and COPD patients. RESULTS: In the severe asthma group, the 6MST was higher post-PR (504⯱â¯150, pâ¯=â¯0.043) and at M12 (538⯱â¯163, pâ¯=â¯0.016) compared with baseline (450⯱â¯148). The VSRQ score was higher at M12 (39.0⯱â¯18.6, pâ¯=â¯0.049) but not post-PR (38.7⯱â¯15.8, pâ¯=â¯0.119) in comparison with baseline (32.2⯱â¯12.4). There was no difference in the HAD scores between baseline, post-PR and M12. PR outcome was not significantly different between severe asthma and COPD patients at short and long term (pâ¯>â¯0.05). CONCLUSION: In severe asthma, home-based PR is associated with improved exercise tolerance and quality of life on a long-term basis but does not modify anxiety and depression.
