This trial is an open-label, randomized, controlled trial evaluating the safety and efficacy of fecal microbiota transplantation (FMT) for the treatment of the recurrence of Clostridium difficile infection (CDI) as compared to standard antibiotic therapy. Clostridium difficile infection (CDI) has increased in incidence and severity over the last decade and is associated with poor outcomes including increased morbidity, mortality, and healthcare costs (1-8). Relapse occurs in 15-35% of patients after the first episode of CDI and 45-65% of patients who have one relapse will experience a subsequent relapse (9, 10). Dysbiosis - decreased diversity of the fecal microbiome - is thought to contribute to the high rate of relapse (11). FMT quickly and successfully restores normal intestinal microorganisms of the diseased patient via infusion of a liquid stool preparation from a healthy donor. FMT resulted in disease resolution in ~90% of cases reported in a systematic review and meta-analyses without any significant adverse events noted (12, 13).
