Randomized Controlled Trial Clinical Trial
The efficacy of inhaled corticosteroids in the management of non asthmatic chronic airflow obstruction.
The aims of this investigation were to evaluate the efficacy of regular inhaled beclomethasone in the control of symptoms and lung function with non-asthmatic smoking related obstructive pulmonary disease and to evaluate the relationship between clinical responses to a short course of oral prednisone and longer term outcomes using inhaled steroid. ⋯ Our results indicate that in non-asthmatic chronic obstructive pulmonary disease inhaled corticosteroid fails to achieve significant improvements in either lung function or symptoms. The response to a "trial of steroid" using oral prednisone is not clinically helpful in selecting the small number of patients who may subsequently benefit from this form of therapy.
