Treatment of hospitalized patients with community-acquired pneumonia.

Effective empiric treatment of pneumonia requires antibiotic coverage against gram-negative and gram-positive pathogens, including drug-resistant isolates. We compared the safety and efficacy of intravenous (i.v.) cefepime (2 g administered every 12 h) to those of i.v. ceftriaxone (1 g administered every 12 h) for the empiric treatment of hospitalized patients with community-acquired pneumonia. Of the 115 patients randomized to the study, 86 (cefepime recipients, n = 40; ceftriaxone recipients, n = 46) were evaluated for clinical efficacy (clinically evaluated patients). Favorable clinical outcomes (cure or improvement) were comparable among clinically evaluated patients in the cefepime and ceftriaxone treatment arms (95.0 versus 97.8%, respectively; 95% confidence interval for treatment difference [data for ceftriaxone group minus data for cefepime group], -5.1 to +10.8%). The most common bacteria isolated from patients in both treatment groups were Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. In clinically evaluated patients with a microbiologic response, all (100%) of the 32 pathogens from cefepime-treated patients and 97.4% (38 of 39) of the pathogens from ceftriaxone-treated patients were eradicated (documented or presumed eradication). The one persistent infection in the ceftriaxone group was caused by Pseudomonas fluorescens. Both treatments were well tolerated. Our data thus suggest that cefepime and ceftriaxone have comparable safety and efficacy for the treatment of pneumonia in hospitalized patients.
