简要总结

The primary objective of this study is to demonstrate that a rifampin-free regimen is non-inferior to the rifampin-containing regimen in terms of all-cause mortality in staphylococcal prosthetic valve endocarditis within 6 months after randomization.

详细描述

A rifampin-based treatment is recommended for prosthetic valve infective endocarditis caused by staphylococcus to act on the biofilm. However, the use of this molecule is associated with numerous adverse effects (digestive disorders, hepatotoxicity, hypersensitivity…) and drug interactions, particularly common in patients with prosthetic valves. In a retrospective study comparing patients receiving antibiotic therapy with rifampin versus without rifampin in staphylococcal prosthetic infective endocarditis (Le Bot et al. CID 2021, PMID: 32706879), there was no difference in terms of mortality or relapse between the two groups, but a longer hospital length of stay in the rifampin-treated group.

The aim of this multicentre randomized controlled trial is to demonstrate the non-inferiority of a rifampin-free regimen compared to a rifampin-combined regimen.

  • Extreme weight (< 45 kg or > 150 kg)
  • Patients with confirmed prosthetic vascular graft infection or orthopedic-device-related infection
  • Patients treated with rifampin for infections other than endocarditis, such as tuberculosis
  • Pregnancy or breastfeeding woman
  • Inclusion in another drug clinical trial

研究组 & 干预措施

Rifampin-free regimen.

Experimental

The experimental arm of the study involves the removal of rifampicin from the antibiotic regimen recommended by the 2023 ESC (European Society of Cardiology) guidelines and the 2025 French guidelines (AEPEI/SPILF) for the treatment of staphylococcal prosthetic valve endocarditis.
