6 Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable disease with some significant extrapulmonary effects that may contribute to the severity in individual patients. Its pulmonary component is characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lung to noxious particles or gases. GOLD 2007

31 Welche Antibiose?? Metaanalyse von 19 RCT s, 7405 Pts.; : There was no difference regarding treatment success in intentionto-treat and clinically evaluable patients between macrolides and quinolones, A/C and quinolones or A/C and macrolides. The treatment success in microbiologically evaluable patients was lower for macrolides compared with quinolones (odds ratio (OR) 0.47, 95% confidence interval (CI) ). Fewer quinolonerecipients experienced a recurrence of ABECB after resolution of the initial episode compared with macrolide-recipients during the 26-week period following therapy. Adverse effects in general were similar between macrolides and quinolones. Administration of A/C was associated with more adverse effects (mainly diarrhoea) than quinolones (OR 1.36, 95% CI ).

34 Prävention? Black P; Staykova T; Chacko E; Ram FS; Poole P. Prophylactic antibiotic therapy for chronic bronchitis. Cochrane Database Syst Rev. 2003:CD Metaanalyse 9 Studien, 1055 Pts. Conclusion: Prophylactic antibiotics in chronic bronchitis / COPD have a small but statistically significant effect in reducing the days of illness due to exacerbations of chronic bronchitis. They do not have a place in routine treatment because of concerns about the development of antibiotic resistance and the possibility of adverse effects. The available data are over 30 years old, so the pattern of antibiotic sensitivity may have changed and there is a wider range of antibiotics in use.

37 Reduction in Number of Acute Exacerbations of COPD with Moxifloxacin in Patients with Mucopurulent/Purulent Sputum: A PULSE Study Sub-Analysis, [Publication Page: A962] S. Sethi, Buffalo, NY Background: The PULSE study demonstrates that intermittent pulsed antimicrobial therapy with moxifloxacin (MXF) decreases exacerbations of chronic obstructive pulmonary disease (COPD) when compared to placebo. The effectiveness of this pulsed MXF therapy was assessed in a patient subgroup enrolled in PULSE patients with mucopurulent (MP)/purulent (P) sputum at baseline. Methods: The PULSE study was a double-blind randomized clinical trial of intermittent MXF 400mg PO q.d. or placebo for 5 days every 8 weeks for 6 cycles. Post-hoc analysis was used to compare frequency of exacerbations between the two treatments in patients with MP/P sputum at baseline. Logistic regression analysis was performed and adjusted for region and pre-therapy % predicted FEV1. Results: In the end of treatment (EOT) per protocol (PP) population, 167/351 (47.6%) MXF- and 156/387 (40.3%) placebo-treated patients had MP/P sputum at their baseline, stable condition. For the primary outcome variable, the number of exacerbations during 48 weeks of therapy, was reduced from a mean (SD) of 1.0 (1.3) in the placebo group to 0.8 (1.3) in the MXF group. The adjusted odds ratio for exacerbation (95% CI) was (95% confidence interval 0.355, 0.839; p=0.006) in the MXF arm compared to placebo arm. Conclusions: Among patients with COPD who produced mucopurulent or purulent sputum in their stable baseline state, intermittent pulsed therapy with MXF was associated with a relative 45.5% reduction in the odds of exacerbations in the PP (EOT) population, compared with placebo. This subgroup of patients therefore are good candidates for such therapy, when their standard therapy for COPD is inadequate in preventing exacerbations. Funding source: Bayer HealthCare.

38 Pulsed moxifloxacin therapy and health status in patients with acute exacerbations of chronic obstructive pulmonary disease (the PULSE study) Paul Jones, 1 Thomas Evers, 2 Daniel Haverstock, 3 Sanjay Sethi St George's, University of London, London, United Kingdom; 2 Bayer HealthCare AG, Global Health Economics and Reimbursement, Wuppertal, Germany; 3 Bayer Pharmaceuticals Corporation, Global Biostatistics Department, Connecticut, United States of America; 4 Division of Pulmonary, Critical Care and Sleep Medicine, State University of New York, Western New York Healthcare System, State University of New York, and Department of Veterans Affairs, Western New York Healthcare System, Buffalo, NY, Unit. Background: The PULSE study showed that chronic intermittent pulsed therapy with moxifloxacin (MXF) reduced acute exacerbations of chronic obstructive pulmonary disease (AECOPD), versus placebo. Health status was a secondary endpoint. Methods: In the PULSE study, patients received MXF 400 mg PO q.d. or placebo for 5 days every 8 weeks for six cycles. Health status was measured by St George's Respiratory Questionnaire (SGRQ). Post hoc analyses were performed on mean change in SGRQ Symptom score (SGRQ-SDS), from baseline to week 48, with cut-off points for a clinically relevant response retrospectively defined as 4 or 8 units. Results: A total of 1,149 stable COPD patients received MXF (N=569) or placebo (N=580) of whom 1,008 (MXF, N=490; placebo, N=518) provided SGRQ data. Compared with placebo, significantly more MXF patients either improved, or had no change in SGRQ-SDS, and significantly fewer had deteriorations in SGRQ-SDS (Table 1).
