Abstract
BACKGROUND: Exacerbations contribute substantially to the morbidity and mortality associated with chronic obstructive pulmonary disease (COPD). OBJECTIVES: To assess whether prophylactic antibiotic treatment reduces exacerbations in patients with COPD and/or chronic bronchitis. METHODS: Medline, EMBASE, Cochrane Central Register of Controlled Trials, Koreamed and references from relevant publications were searched up to October 2011. Randomised controlled trials comparing the effect of any prophylactic antibiotics with placebo for at least 3 months were included. The co-primary outcomes were the frequency of exacerbations of COPD or chronic bronchitis and adverse treatment events. RESULTS: A total of 19 trials involving 3932 subjects were included in the analysis: 5 recent trials included patients with moderate to severe COPD, whereas 14 older trials included patients with chronic bronchitis. The use of antibiotics significantly reduced the rate of COPD exacerbations (risk ratio [RR] 0.73, 95%CI 0.66-0.82), the number of chronic bronchitis exacerbations (standardised mean difference -0.23, 95%CI -0.35--0.11) and the proportion of patients with exacerbations of chronic bronchitis (RR 0.93, 95%CI 0.87-0.99). CONCLUSION: Prophylactic antibiotic treatment has a significant effect in reducing exacerbations in patients with COPD and/or chronic bronchitis.
