Lung function with forced expiratory volume in 1 second (FEV1), forced vital capacity, and COPD-assessment test (CAT) were checked every 2 months. The frequency of acute exacerbations and number of pneumonia events were measured. The duration of the study period was 1 year. Results: In total, 237 COPD patients were randomized into the two treatment arms (115 in the HD group, 122 in the MD group). The FEV1 level was significantly improved in the patients in the HD group compared with those in the MD group (HD 103.9±26.6 mL versus MD 51.4±19.7 mL, P,0.01) at the end of the study. CAT scores were markedly improved in patients using an HD compared to those using an MD (HD 13±5 versus MD 16±7, P=0.05). There was a significant difference in the percentage of annual rates in acute exacerbations (HD 0.16 versus MD 0.34, P,0.01) between the two groups. The incidence of pneumonia was similar in the two groups (HD 0.08 versus MD 0.10, P=0.38). Conclusion: COPD patients treated with high doses of ICS had more treatment benefits and no significant increases in the incidence in pneumonia. Higher-dose ICS treatment may be suitable for COPD therapy. ? 2014 Cheng et al. |
