Fecal Microbiota Transplantation is Safe and Efficacious for Recurrent or Refractory Clostridium difficile Infection in Patients with Inflammatory Bowel Disease
Bibliographic record
Abstract
BACKGROUND: New treatments are needed as Clostridium difficile infection (CDI) is becoming increasingly formidable. Fecal microbiota transplantation (FMT) has a 90% success rate in the treatment of recurrent CDI. However, evidence regarding its safety, efficacy, and effect on disease activity in patients with inflammatory bowel disease (IBD) is lacking. METHODS: This cohort study used data from 8 national and international academic centers. Patients with established IBD who underwent FMT for recurrent CDI were followed for a minimum of 3 months. The primary outcome was CDI recurrence at 3 months after FMT. The secondary outcomes were (1) IBD activity and severity at 3 months based on the judgment of the treating physician, endoscopic findings, and clinical disease activity scores; and (2) safety. RESULTS: Sixty-seven patients were included in the analysis. Thirty-five (52%) had Crohn's disease, 31 (46%) ulcerative colitis, and one indeterminate colitis with 43 (64%) patients on an immunosuppressive agent at the time of FMT. The initial FMT was successful in 53 (79%) patients. After the FMT, IBD disease activity was reported as improved in 25 (37%), no change in 20 (30%), and worse in 9 (13%) patients. Serious adverse events included colectomy (1.4%), hospitalization for CDI (2.9%), hospitalization for IBD flare (2.9%), small bowel obstruction (1.4%), CMV colitis (1.4%), and pancreatitis (1.4%). DISCUSSION: The overall CDI cure rates were high, with a large percentage of patients experiencing clinical improvement of their IBD after FMT. A minority of patients developed an IBD flare. No severe adverse events directly attributable to FMT were found in this largest reported series of recurrent or refractory CDI patients with concurrent IBD.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
