What this research studies

You can join if you've had or are planning to have an FMT or a live biotherapeutic product; sites across North America enroll participants. The registry collects medical history, treatment details, and follow-up information using medical record review, regular questionnaires, and sometimes stool or other samples. Researchers track short-term outcomes like infections and procedure results as well as long-term health effects that might appear years later. The goal is to identify rare risks, improve donor and product screening, and guide safer care for people with C. difficile.

Who could benefit from this research

Good fit: Ideal participants are people treated with or planning to receive fecal microbiota transplant or live biotherapeutic products, especially those with recurrent, severe, or fulminant C. difficile infection.

Not a fit: People without C. difficile infection or who are not receiving FMT or related microbiome therapies are unlikely to gain direct benefit from this registry.

Why it matters

Potential benefit: If successful, the registry could make FMT and similar therapies safer and more effective by identifying rare infections, long-term effects, and best practices for screening and treatment.

How similar studies have performed: FMT is already effective for treating recurrent C. difficile infection, but recent reports of transmitted multidrug-resistant organisms and other pathogens mean ongoing registry data are needed to understand and prevent rare harms.
