Abstract

This report describes a post-hoc analysis of two large studies of typical community-acquired pneumonia (CAP) in hospitalized patients, focusing on demographics, disease characteristics, and outcome in patients with and without chronic obstructive pulmonary disease (COPD). In both studies, ertapenem 1 g IV daily was compared with ceftriaxone 1 g IV daily as initial antimicrobial therapy. Clinically improving patients could be switched to oral antibiotic therapy after 3 days. Of the 857 patients treated in both studies, 264 (31%) had COPD. The proportions of patients who were male, were >/=65 years of age, had a Pneumonia Severity Index of IV/V, or had Haemophilus influenzae isolated in a baseline culture were higher in patients with COPD. Streptococcus pneumoniae was the most common pathogen both in patients with and without COPD. Clinical response rates in assessable patients 7-14 days after completion of therapy for the combined treatment groups were 90% (187/208) for patients with COPD and 93% (424/456) for those without COPD (odds ratio 0.7 [95% CI, 0.4-1.2], P = 0.17). Of assessable COPD patients, 109/121 (90%) treated with ertapenem and 78/87 (90%) treated with ceftriaxone achieved a favorable clinical response (odds ratio...Continue Reading
