Brief summary

The goal of this study is to determine the outcome of patients with recurrent CDI treated with fresh FMT versus frozen-and-thawed FMT in a randomized controlled trial. The specific objectives are to evaluate the safety of both types of FMT and to compare the clinical response, treatment failure and relapse rate in patients treated with fresh FMT compared to those treated with frozen-and-thawed FMT; also to assess the functional health and well-being of patients in each arm using a validated tool. The metagenomics will also be conducted from the stool samples collected from select patients from each arm: pre and post treatment and the matching donors. The metagenomics data will be used to determine the bacteria which may have contributed to the cure of CDI.

Interventions

BIOLOGICALFresh FMT

Participants will receive fresh FMT (supernatant of fecal specimen mixed with water) on day 1. If cure is not reached at day 5 (+3) a repeat FMT will be performed

BIOLOGICALFrozen-and-Thawed FMT

Participants will receive frozen-and-thawed FMT (supernatant of fecal specimen mixed with water) on day 1. If cure is not reached at day 5 (+3) a repeat FMT will be performed

Inclusion criteria

Patient inclusion criteria 1. Age 18 years or older. 2. Able to provide informed consent. 3. Laboratory or pathology: confirmed diagnosis of recurrent CDI with symptoms (defined below) within the previous 180 days. 4. ≥ 2 episodes of CDI within 6 months and/or ongoing symptoms consistent with CDI despite treatment with oral vancomycin at a dose of at least 125 mg 4 times daily for at least 5 days. Symptoms of CDI, diarrhea defined as: 3 or more unformed bowel movements in 24 hours for a minimum of 2 days with no other causes for diarrhea. Subjects will be required to have laboratory or pathology-confirmed diagnosis of recurrent C. difficile infection where recurrence is defined as return of diarrhea and positive stool test after a period of symptom resolution within 8 weeks of the first episode and has received at least a 10-day course of standard antibiotic therapy.
