Washed Microbiota Transplantation in Solid Organ Transplantation

November 24, 2024 updated by: Faming Zhang, The Second Hospital of Nanjing Medical University

Washed Microbiota Transplantation for Postoperative Complications in Solid Organ Transplantation

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Stool frequency and consistency
Time Frame: Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT
Stool frequency and consistency will be evaluated according to the Bristol Stool Form Scale (BSFS, ranging from type 1 - type 7)
Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT
Gastrointestinal Symptom Rating Scale (GSRS)
Time Frame: 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).
Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT
Pathogen detection and culture
Time Frame: Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT
Pathogen was detected and cultured from serum, urine, stool and so on before and after WMT.
Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adverse events(AEs)
Time Frame: Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT
AEs will be evaluated according to NCI Common Terminology Criteria for Adverse Events(CTCAE), Version 5.0
Baseline, 1-week, 2-week, 1-month, 2-month, 3-month post WMT
Gut microbiota
Time Frame: Baseline, 3-month post WMT
Changes in intestinal microbial composition and diversity in the stool samples of patients before and after WMT
Baseline, 3-month post WMT
Quality of life by SF-36
Time Frame: Baseline, 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, mental health). Lower scores represent more dysfunction.
Baseline, 3-month post WMT
