简要总结
The purpose of this study is to learn the efficacy and safety of fecal microbiota transplantation (FMT) using stool from a donor with low proteolytic activity and containing the bacteria Alistipes putredinis in patients with irritable bowel syndrome (IBS) and high proteolytic activity. Proteolytic activity is the breakdown of proteins into smaller polypeptides or amino acids.

结局指标
主要结局
Percentage of responders
时间窗: 12 weeks
Number of subjects receiving the donor fecal microbiota transplantation identified as a responder defined as a decrease of ≥50 points in Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) from baseline. The Irritable Bowel Syndrome Symptom Severity Score scale has a possible range of scores from 0-500. Mild cases are classified as a score of 75-175, moderate cases are classified as a score of 175-300, and severe cases are classified as a score of \>300.
次要结局
- Changes in in vivo excretion of 2-24 hr lactulose excretion(Baseline, 12 weeks)
- Change in level of fecal proteolytic activity(Baseline, 12 weeks)
- Global Adequate Relief Questionnaire(12 weeks)
- Number of weekly responders(12 weeks)
- Alistipes putredinis proportion post-FMT(12 weeks)
