RATIONALE: Antimicrobial therapy of chronic bronchitis exacerbations in patients with severe chronic obstructive pulmonary disease (COPD) is based on empiric antibiotic treatment.
OBJECTIVES: To evaluate the efficacy of prulifloxacin versus levofloxacin therapy in severe COPD patients with exacerbations of chronic bronchitis.
METHODS: This study involved a multicenter, parallel, double-blind, randomized clinical trial. Patients aged 40 years or older, smokers, or ex-smokers (>10 pack-years) with spirometrically confirmed severe COPD (FEV1 ≤ 50% predicted and FEV1/FVC ratio < 0.7) and diagnosed with an acute exacerbation of chronic bronchitis were enrolled in the study. Patients were randomized to receive prulifloxacin 600 mg once a day or levofloxacin 500 mg once a day for 7 days.
MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was clinical assessment at the TOC visit (7-10 days after the end of treatment) of signs and symptoms of exacerbation, namely sputum purulence, sputum volume, dyspnoea, cough and body temperature assessed through semi-quantitative scales. The ITT population included 346 (174 prulifloxacin, 172 levofloxacin) out of 351 treated subjects. A total of 161 patients with prulifloxacin (92.5%) and 166 with levofloxacin (96.5%) were considered cured at TOC (the difference in the percentage of cured patients was -3.98 with 95%CI of -8.76; 0.79). At the 6-month follow-up, the rates of patients with no relapse of AECB were higher than 95% in both the prulifloxacin and levofloxacin groups.
CONCLUSIONS: Both prulifloxacin and levofloxacin showed efficacy rates higher than 90% in the treatment of severe COPD patients with exacerbations of chronic bronchitis, with no statistically significant differences between the two antibiotics. The long-term follow-up confirmed a very low incidence of relapse, endorsing the appropriateness of this therapeutic approach. EUDRACT no. 2006-004167-56.
