Meta Analysis
Efficacy and Safety of Different Doses of Systemic Corticosteroids in COPD Exacerbation.
Although systemic corticosteroids (SCS) have long been used to treat patients with COPD exacerbation, the recommended dose remains controversial. We aimed to perform a meta-analysis and an indirect treatment comparison to investigate the efficacy and safety of different doses of SCS in subjects with COPD exacerbation. ⋯ This meta-analysis indicates that low-dose SCS (initial dose ≤ 40 mg PE/d) was sufficient and safer for treating subjects with COPD exacerbation, and it was noninferior to higher doses of SCS (initial dose > 40 mg PE/d) in improving FEV1 and reducing the risk of treatment failure. However, our findings need to be verified in head-to-head randomized controlled trials.
