Vancomycin-resistant enterococcus bloodstream infection successfully managed with oritavancin and fosfomycin as sequential treatment

AbstractBloodstream infections caused by vancomycin-resistant enterococci are increasingly reported and a consensus therapy does not exist. Oritavancin has shown good antimicrobial activity against VRE, but its use is mainly limited to skin, soft tissue, and/or bone infections. Fosfomycin is increasingly used for enterococcal infections (including bloodstream infections and endocarditis) as a partner drug given its anti-biofilm and synergistic properties. Recently in vitro and in vivo synergism between oritavancin and fosfomycin against VRE isolates has been demonstrated. Herein we report the case of a hematologic patient with a VRE bloodstream infection successfully treated with oritavancin and fosfomycin as sequential treatment.Keywords: Enterococcusbloodstream infectionsfosfomycinoritavancinVREoutcomehospital acquired infections Disclosure statementNo potential conflict of interest was reported by the author(s).
