Systemic Glucocorticoids in Sever Exacerbations of COPD.

Objective: This study aimed to compare the efficacies of 3-day and 10-day courses of methylprednisolone (MP) treatment in severe COPD exacerbations necessitating hospitalization for respiratory failure. Design: Prospective, randomized, single-blind study. Setting: Tertiary-care center. Patients and methods: Thirty-six patients were included in the study and randomized into two groups: group 1 received MP, 0.5 mg/kg q6h for 3 days, and group 2 was administered the same dosage of MP for the first 3 days, after which it was tapered and terminated on the tenth day. There was no difference between the groups for age, baseline FEV[sub 1], PaO[sub 2], PaCO[sub 2], and pH levels. One patient in group 1 who developed pneumothorax and one patient in group 2 who had steroid-related psychosis could not complete the study. Results: Both groups showed significant improvements in PaO[sub 2] and FEV[sub 1] levels, but these were more marked in group 2 (p = 0.012 and p = 0.019, respectively). There was a significant increase in FVC levels in group 2 only (p = 0.003). Group 2 also had a more marked improvement in dyspnea on exertion. There was no difference between the two groups with regards to other parameters, including pH, PaCO[sub 2] levels, and other symptom scores. Six patients in group 1 and five patients in group 2 developed new exacerbations within the following 6 months. Hyperglycemia occurred in two patients in each group. Conclusion: In severe COPD exacerbations, a 10-day course of steroid treatment is more effective than a 3-day course in improving the outcome, but has no benefit in reducing exacerbation rates.
