Therapy for Clostridium difficile infection - any news beyond Metronidazole and Vancomycin?

INTRODUCTION: Infections with Clostridium difficile (CDI) represent a major burden for the health care system. Treatment is generally by antibiotic therapy with metronidazole and vancomycin, but efficacy remains suboptimal. Areas covered: This review discusses established and emerging treatment options for CDI, and current therapeutic guidelines, taking into account disease severity and risk of relapse. Expert commentary: New therapeutic approaches, including antibodies and new classes of antibiotics, and new measures for preventing infection with vaccines are under development in phase II/III clinical trials. We performed a systematic literature review using the search terms 'Clostridium difficile' and 'treatment'.
