Cefepime versus cefotaxime for empirical treatment of bacterial pneumonia in HIV-infected patients: an open, randomized trial.

An open, randomized, multicentre clinical trial was conducted to compare the efficacy and safety of cefepime 2 g iv bd (2 g tds daily in cases of Pseudomonas aeruginosa pneumonia) with cefotaxime 2 g iv tds, in the empirical treatment of bacterial pneumonia in HIV-infected patients. The primary end-point was effectiveness after 3-5 days of treatment, taking success to be when the study drug was continued during this period of time. Clinical and bacteriological responses at end of treatment (EOT) were also evaluated. Analyses of the intention-to-treat population (n = 160) and the as-per-protocol groups (n = 150) were carried out. Treatment groups were comparable with regard to sex, age, HIV status and degree of severity of pneumonia. The primary end-point for cefepime was considered successful for the intention-to-treat and as-per-protocol groups in 85.7% and 93.5% of cases, respectively, and for cefotaxime, in 77.6% and 80.8% of cases, respectively (P = 0.22 and P = 0.02). In the as-per-protocol group, cefotaxime treatment was independently related to failure at the primary end-point. A satisfactory clinical response in the intention-to-treat population was observed in 83.3% of cefepime and 82.9% of cefotaxime patients. Bacteriological cure was obtained in 100% of evaluable cefepime and 93.4% of evaluable cefotaxime patients at EOT. Safety of the study drugs was comparable in both treatment groups. Cefepime 2 g iv bd was at least as effective and as well tolerated as cefotaxime 2 g iv tds in the treatment of bacterial pneumonia in HIV-infected patients.
