About

Safety and efficacy of direct thrombin inhibitors versus enoxaparin in patients with staphylococcus aureus bacteraemia.

The study hypothesizes that inhibition of the coagulase-activity of S. aureus by direct thrombin inhibitors is safe and translates into a better outcome of patients with S. aureus bacteremia.

Full description

Single center randomized controlled trial of direct thrombin inhibitors versus standard enoxaparin.

  • Feasibility: proportion of patients eligible for randomization; clinically attained concentration of DTI and resulting staphylothrombin inhibition

  • Safety: bleeding events (major/ clinically relevant non-major)

  • Efficacy: thrombotic events during the thromboprophylactic treatment + 3 days

  • Secondary outcome measures

    • Coagulation parameters: evolution of D-dimers from day 0-4; other lab parameters of coagulation (PT/APTT/fibrinogen/platelet count)
    • Inflammatory parameters: CRP, white blood cell count, neutrophilia
    • Clinical outcomes: metastatic infections, assessed clinically or by PET/CT; relapse of S. aureus bacteremia; defervescence; persistent positive blood cultures; hospital stay, mortality.
