Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with two or more recurrences of C. difficile infection who have not responded to standard antibiotic therapies.

Probably not a fit

Patients under 16 years old or those with acute severe colonic dilation are unlikely to benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of fecal microbiota transplantation (FMT) performed via colonoscopy for patients suffering from recurrent Clostridium difficile infections. The procedure involves transplanting stool from a healthy donor into the colon of the patient to restore beneficial gut bacteria. The study aims to standardize the FMT protocol and assess its success rates, costs, and impact on hospitalizations compared to traditional antibiotic treatments. Historical controls will be used to measure outcomes against past patient data.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the recurrence of C. difficile infections and associated healthcare costs for patients.

How similar studies have gone: Previous studies have shown high success rates for fecal microbiota transplantation in treating recurrent C. difficile infections, indicating a promising approach.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Two or more recurrences of C. difficile infection (CDI) with recurrence defined as a positive test result, e.g. Polymerase Chain Reaction (PCR) test and with appropriate symptoms within 2-8 weeks of last positive result, provided that symptoms from earlier episode resolved with or without therapy.
* Failed standard therapy with oral metronidazole and/or oral vancomycin
* One or more episodes of severe CDI resulting in hospitalization and not responding to standard antibiotic therapy. Hospitalization for CDI occurs in the setting of severe diarrhea, abdominal pain and signs of systemic toxicity

Exclusion criteria:

* Age \<16 years old
* patients with acute severe colonic dilation at risk for colonic perforation
