Microbiota Transplantation in Solid Organ Transplantation

Recruiting

• Conditions: Solid Organ Transplant Complications

• Registration Number: NCT06730451
• Lead Sponsor: The Second Hospital of Nanjing Medical University

Brief Summary

Solid organ transplantation (SOT), an alternative therapy for end-stage diseases, offers increased longevity and better quantity of life. Posttransplant complications such as gastrointestinal symptoms, infection, and graft rejection increase risk with graft failure and death. However, the treatment of abovementioned complications remains unsatisfactory. Gut dysbiosis has been reported in patients with SOT, especially in patients with posttransplant complications. Recipients are more susceptible to gut dysbiosis as long-term use of immunosuppressants, antibiotics and corticosteroids. Restoring gut microbiome may be a promising therapy for posttransplant complications. Washed microbiota transplantation (WMT) is a newly improved methodology of fecal microbiota transplantation based on automatic facilities, washing process and a new delivery routine. In this study, investigators aimed to evaluate the efficacy and safety of WMT for postoperative complications in SOT.

Primary Outcome Measures

Name	Time	Method
Gastrointestinal Symptom Rating Scale (GSRS)	Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT	GSRS is a 15-item instrument designed to assess the symptoms associated with common GI disorders. The GSRS consists of 5 subscales (reflux, diarrhea, constipation, abdominal pain, and indigestion) producing a mean subscale score ranging from 1 (no discomfort) to 7 (very severe discomfort).
Stool frequency and consistency	Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT	Stool frequency ≥3 times per day was considered as diarrhea. Higher frequency represents more severe diarrhea. Stool consistency will be evaluated according to the Bristol Stool Form Scale ranging from type 1 - type 7. Type 1 and 2 indicate constipation, Type 3 and type 4 indicate normal defecation, Type 5, 6 and 7 indicate diarrhea.

Secondary Outcome Measures

Name	Time	Method
The changes in gut microbiota composition by sequencing faecal metagenome	Baseline, 1-month, 3-month post WMT	The changes in gut microbe composition before and after WMT were evaluated by sequencing faecal metagenome.
Quality of life by 36-Item Short Form Health Survey(SF-36)	Baseline, 1-month, 3-month post WMT	SF-36 is a 36-item questionnaire to assess the impact of disease on daily life. The SF-36 consists of 8 subscales (vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health) ranging from 0 to 100. Lower scores represent more dysfunction.
