    Abstract:
    It remains unclear whether inhaled corticosteroids can produce the maximum benefits of corticosteroids in patients with chronic obstructive pulmonary disease (COPD). To assess the additive effects of 30 mg/day prednisolone to high-dose, inhaled beclomethasone dipropionate (BDP), we conducted a randomised double-blind, placebo-controlled cross-over trial. The study population consisted of 21 men with stable COPD. The mean age of the patients was 69.1 +/- 6.8 years, and FEV(1)was 0.86 +/- 0.28 l. Seventeen out of the 21 patients (81%) were considered susceptible to steroids in a previous trial (FEV(1)increased at least 15% from baseline after receiving 14 days of 30 mg/day prednisolone). All of the patients had been on 1600 microg/day BDP for more than 3 months. Spirometry was performed before the entry, and at the end of 3-week placebo and prednisolone periods. The peak expiratory flow (PEF), symptoms, and Guyatt's Chronic Respiratory Disease Questionnaire (CRQ) as a disease specific health-related quality of life over the last seven days of each period were also evaluated. Although a marginal increase in PEF was found during the prednisolone period, no significant differences in FEV(1), FVC, symptoms or CRQ scores were observed between the two treatment periods. We conclude that the therapeutic effects of steroid therapy may be achieved by the long-term use of high-dose, inhaled corticosteroid in some patients with stable COPD.
