What this trial studies

This observational study aims to create a national cohort registry in France for patients undergoing fecal microbiota transplantation (FMT) for Clostridium difficile infections (CDI). It will collect data on the methods used, efficacy, and side effects of FMT, as well as information on stool donors. The study addresses the increasing incidence and severity of CDI, particularly in recurrent cases, which pose significant therapeutic challenges. By evaluating the safety and effectiveness of FMT, the study seeks to provide valuable insights into this treatment option.

Who should consider this trial

Good fit: Ideal candidates include adults with severe refractory or recurrent CDI who are indicated for FMT.

Not a fit: Patients who do not understand written and spoken French may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment outcomes for patients suffering from recurrent Clostridium difficile infections.

How similar studies have performed: Previous studies have shown that fecal microbiota transplantation is superior to antibiotic therapy in reducing recurrences of CDI, indicating a promising approach.
