Early FMT for C.Difficile

Clostridium difficile infection (CDI) has increased worldwide in both frequency and severity. It is the leading cause of hospital acquired infection in developed countries and has been associated with at least 14,000 deaths per year in the United States. With 3 million cases/ year, the annual cost for treating the infection is exceeding 3 billion dollars. It can also have a profound negative impact on quality of life. The investigators believe that patients who are at high risk of relapse after a first CDI episode would benefit from early fecal microbial transplant (FMT). The proposed study will produce preliminary data regarding safety and efficacy and potential for cost effectiveness for the use of early fecal transplant in those patients with their first episode of non-refractory CDI who are predicted to have a high rate of recurrence based on previously published risk factors. The investigators will be better prepared to test the efficacy of this approach in a future multicenter clinical trial in a randomized controlled fashion. The purpose of this study is to compare the effectiveness and safety of early fecal transplant using donor stool from a healthy person in a group of patients who are diagnosed with their first episode of Clostridium difficile infection and are predicted to have a high chance of the infection returning against a similar group of patients who receive current standard of care for treatment of C.difficile. The investigators hypothesize: * that clinical remission rates at 12 weeks as noted by absence of clinical symptoms and/or negative C.difficile stool polymerase chain reaction (PCR) will be greater in the experimental arm compared to the control arm * that patients in the experimental group will have a low microbial diversity prior to FMT but will exhibit a high microbial diversity after the FMT that resembles the respective donor * that the microbial diversity will be diminished in both groups at the time of enrollment, but the experimental group will exhibit a higher microbial diversity compared to the control population at 12 weeks * that patients in both groups will exhibit poor quality of life at the time of enrollment, however, the experimental group will demonstrate higher quality of life compared to the control group at follow up after completion of treatment * that costs incurred by the experimental group will be less than the control group
