Clostridium difficile infection (CDI) is a major cause of infectious diarrhea and the most important cause of nosocomial diarrhea. Recurrent forms are a major problem with this infection. The use of fecal microbiota transplantation (FMT), FMT appears in the most recent European and North American recommendations. There is no cohort or multicenter registry in France prospectively collecting FMTs, the methods used, their efficacy and side effects. Likewise, there is no prospective collection focused on the cohort of stool donors. A large national cohort of patients who have undergone FMT as part of routine care as well as donors, is essential for evaluating the safety of FMT.
Clostridium difficile infection (CDI) is a major cause of infectious diarrhea and the most important cause of nosocomial diarrhea. For 20 years, the incidence of CDI has continued to increase. In addition, the severity of infections is also increasing (mortality: 5% in 1990 against 13.8% in 2003; complications: 6% in 1990 against 18% in 2003). Recurrent forms represent a major problem of this infection. Indeed, after a first episode, the risk of a first recurrence is around 15 to 25% and this risk then increases with each recurrence, reaching 45% then 65% after a first and second recurrence respectively. These Recurrent forms pose a real therapeutic problem, causing significant morbidity (repeated hospitalizations, time off work, etc.) and substantial mortality. Patients with CDI are 2.5 times more likely to die within 30 days of infection than uninfected patients, regardless of age or comorbidities. The mortality rate is also higher in patients with a recurrent form than in those with a single episode. Furthermore, the antibiotics usually used are only marginally effective in cases of recurrent CDI. Numerous studies, including two randomized trials, have shown that fecal microbiota transplantation (FMT), is superior to antibiotic therapy in reducing subsequent recurrences, the use of FMT in this indication appears in the most recent European and North American recommendations. Cosmic-FMT cohort aims to be as representative as possible of the population of patients having FMT for CDI in the context of care.

adverse event rate
In the short term, all adverse events occurring within 24 hours following FMT and within 10 weeks following FMT will be recorded based on both a predetermined list of events of interest as well as on an open declaration. In the medium term, potential adverse events in the patient will be recorded every 6 months for 3 years also based on a predetermined list of events and on an open declaration. Occurrence of at least one SAE at W10 and 3 years according to (i) the clinical characteristics of the donors, (ii) the clinical characteristics of the patients, (iii) the method of preparation and administration of the fecal preparation.
