PWE-078 A Prospective Controlled Pilot Study of Fecal Microbiota Transplantation for Chronic Refractory Pouchitis
Bibliographic record
Abstract
Introduction Faecal microbiota transplantation (FMT) is an effective therapy for Clostridium difficile and possibly inflammatory bowel diseases (IBD). Published data of FMT for inflammatory bowel diseases are reported in case series and case reports. To our knowledge, there are no controlled studies of FMT for IBD. We aimed to conduct a prospective study of FMT for chronic refractory pouchitis. Methods Patients with clinically, endoscopically and histologically confirmed chronic refractory pouchitis; with a pouch disease activity index (PDAI) > 7 were included. Donors were screened by clinical history and serology for HAV, HBV, HCV, HEV, Treponema, HIV, HTLV I/II and stool for M, C+S, C. difficile toxin and parasites. Fresh donor stool was collected within six hours of nasogasric administration of FMT. Stool samples were also collected from patients for analysis of coliform sensitivities before and 4 weeks after FMT. PDAI and Cleveland global quality of life score (CGQoL ) were recorded prior to FMT and four weeks after FMT. Results Eight patients with chronic refractory pouchitis who had undergone restorative proctocolectomy for ulcerative colitis underwent FMT. Three patients had ESBL resistant coliforms on stool analysis prior toFMT. Two of these patients demonstrated a change to ciprofloxacin sensitive coliform following FMT. The mean PDAI prior to FMT was 12. The mean CGQoL was 0.45. At 4 weeks following FMT, no patient had achieved a clinical remission (mean PDAI 11). No improvement in CGQoL was seen (mean 0.44). Conclusion FMT via nasogastric administration was not effective in achieving clinical remission for chronic refractory pouchitis at 4 weeks after FMT. However, in two patients with ESBL resistant coliform, ciprofloxacin sensitivity was regained following FMT and these patients have subsequently been maintained on ciprofloxacin. This suggests FMT may alter the pouch microbiota. Further molecular microbiological analysis is being undertaken to determine the effect FMT had on these patients’ microbiota. In addition, further studies of FMT are required to assess the effect of different methods of FMT that may be more efficacious for this group of patients. Disclosure of Interest None Declared.

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.
