Brief Summary

The primary goal of this proposal is to study the outcome of patients with recurrent Clostridium Difficile Infection (CDI) treated with frozen Fecal Microbiota Transplantation (FMT) in an open-labelled controlled trial. The specific objectives are to evaluate the safety of FMT and to determine the clinical response, treatment failure and relapse rate in patients treated with frozen-and-thawed FMT; to assess the functional health and well-being of patients in each arm using the validated tool, and to determine the feasibility of providing standardized FMT in multiple centres across Canada, including community hospitals. 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.

Detailed Description

CDI is the most frequent cause of healthcare-associated infectious diarrhea in industrialized countries and affects over 300,000 patients each year in the United States. The incidence of CDI has nearly tripled between 1996 and 2005 (from 31 to 84 per 100,000 patient-days) in the United States. The rise in incidence has been accompanied by an increase in disease severity, with mortality in up to 6.9% of cases. According to the Canadian Nosocomial Infection Surveillance Program study conducted from November 1, 2004 through April 30, 2005, the incidence rate of health care-associated CDI for adult patients admitted to Canadian hospitals is 65 per 100,000 patient-days. The same study identified that the overall and attributable mortality of patients with CDI is 16.3% and 5.7%, respectively in Canada, which is similar to the US data.1,17 The associated economic burden has also been significant. Nosocomial CDI increases the cost of otherwise matched hospitalizations by four-fold, translating to greater than $1 billion/year (United States). Since the implementation of mandatory reporting of CDI cases in September 2008 in Ontario, more than 13 health-care facilities declared CDI outbreak in Ontario. There were a number of deaths directly due to CDI in these outbreaks. The management of each outbreak is very costly. The direct attributable costs associated with the outbreak management alone per episode per institution exceeded $1 million (direct communication with a hospital chief financial officer).

There is a growing concern regarding failure of standard antimicrobial therapy. The treatment failure rates for metronidazole, which is the first line therapy for uncomplicated CDI, have risen from 2.5% to greater than 18% since 2000. Recurrence rates are higher among the elderly, and exceed 50% for those over the age 65.20 Recurrence rates exceed 60% for patients who have failed 3 or more episodes of standard antimicrobial therapies. The vanB gene, which is responsible for conferring vancomycin resistance in Enterococcus has been isolated in clostridia, potentially threatening the future use of vancomycin in CDI.

Given the high failure and recurrence rates using the standard therapy, the principal investigator (PI) of this research proposal has been offering FMT for patients who experienced CDI for longer than 6 months despite multiple courses of metronidazole and oral vancomycin therapy. She began treating patients with recurrent CDI with FMT for the following reasons. First, the patients were not responding to the antibiotic treatment. Second, patients may experience intolerance to metronidazole due to metallic taste, significant nausea and loss of appetite, which can lead to further weight loss as patients with CDI experience considerable weight loss. Also, some patients develop irreversible peripheral neuropathy (nerve damage) with long term use of metronidazole. Third, some of the patients with refractory CDI could not afford to continue with oral vancomycin. The cost of oral vancomycin was prohibitive and they were not routinely reimbursed by the public health plan. A 14-day course of oral vancomycin costs $600 and a number of the patients were on this antibiotic for 6 - 18 months at a cost of $7,200 to $21,600 (personal communication with St. Joseph's Healthcare Outpatient pharmacist). The cost of one FMT is approximately $100, which includes the laboratory screening test and the nurse's administration time.
