Prospective, Randomized Dose-Ranging Open Phase II Pilot Study of Quinupristin/Dalfopristin versus Vancomycin in the Treatment of Catheter-Related Staphylococcal Bacteremia

Abstract

 Two different doses of quinupristin/dalfopristin were compared with intravenous vancomycin with regard to the efficacy and safety in the treatment of catheter-related staphylococcal bacteremia. A total of 39 patients were enrolled from 13 centers. For all treated patients with a baseline pathogen, outcome was comparable for all antibiotic study regimens. Discontinuation of the antibiotic for an adverse clinical event occurred in 12% of patients receiving quinupristin/dalfopristin and in 15% of those receiving vancomycin. Quinupristin/dalfopristin may have the potential to serve as an alternative agent in the treatment of catheter-related staphylococcal bacteremia. However, larger prospective randomized trials are required.
