[Faecal microbiota transplantation for Clostridioides difficile infection].

Clostridiodes difficile infection (CDi) is the most common cause of nosocomial diarrhea. Vancomycin, associated or not to metronidazol, is the treatment of choice. However, the rate of treatment failure has increased over the last years and fecal microbiota transplantation (FMT) has emerged as a therapeutic option. To evaluate safety and efficacy of FMT were enrolled 21 hospitalized patients with refractory or recurrent CDi between 2016 and 2019. Fourteen (66%) patients were men and the average age was 76.5 years (range 33-92). Ten had recurrent and 11 refractory CDi, and 18 presented severe and 3 fulminant clinical forms. In 20 cases the FMT was delivered through a nasojejunal tube and in one patient with ileo via enema infusion. Frozen fecal from a stool bank were administered in 20 and in the remaining was used fresh fecal matter. The rate of resolution was observed in 20 patients (95.2%) and none presented recurrence. The response rate was similar in recurrent or refractory forms (9/10 vs 11/11 respectively). One patient with osteomyelitis and multiple organ failure received 2 FMT without response and died. Seven patients (31%) presented mild and self-limited adverse effects. FMT has shown a high efficacy as rescue treatment in cases with refractory or recurrent CDi regardless of severity, with mild side effects. Availability of a stool banks provide reliable, timely and equitable access to FMT for CDi.
