BACKGROUND AND OBJECTIVE: This study investigated whether treating acute exacerbations of COPD (AE-COPD) with levofloxacin modifies the long-term outcome of COPD patients in comparison with standard antibiotic regimens. METHODS: A 6-month open-label clinical trial of AE-COPD patients compared the outcomes of treating with levofloxacin versus standard therapy (clarithromycin, cefuroxime, or amoxicillin/clavulanate) at recommended doses for 10 days. Several variables were analysed: pulse oximetry, FEV1, health-related quality of life, infection-free interval, number of exacerbations, hospitalizations due to an exacerbation and mortality. RESULTS: Of the 116 patients initially enrolled, completion or withdrawal information was available for 50 patients in thelevofloxacin arm and 52 in the standard therapy arm. At the end of the study, there were no differences in mortality (17.8% vs. 22.9%, P = 0.53), number of exacerbations (33 vs. 41, P = 0.40), pulse oximetry (median 91.71% vs. 92.46%, P = 0.18), FEV1 (median 51.31% vs. 47.14%, P = 0.30), health-related quality of life (median 8.63 vs. 10.75, P = 0.94) and infection-free interval (median 112 vs. 101 days, P = 0.72), for the levofloxacin and standard therapy, respectively. However, 12 out of 33 (33.6%) exacerbations treated with levofloxacin required in-hospital management versus 27 out of 41 (65.8%) treated with standard therapy (P = 0.02). CONCLUSION: This preliminary study suggests that 10-day treatment of AE-COPD with levofloxacin is associated with a reduction in hospitalizations compared with standard antibiotics despite there being no significant benefit in other outcome variables.
