简要总结
The main purpose is to evaluate whether the percentage of body weight change from baseline to week 12 is higher than that in the placebo group.
In this randomized, double-blind, placebo-controlled study, 39 patients fulfilling the study criteria will be enrolled in the study. Patients will be randomized(2:1) to either FMT or placebo.
详细描述
This is a randomized, double-blind, placebo-controlled study evaluating fecal microbiota transplantation from lean healthy donors to reduce the patients' weight. Patients wishing to participate will be evaluated whether they qualify for the study regarding the aforementioned inclusion and exclusion criteria. The details of the experiment and potential risks or discomforts involved in it will be presented, after which the patients will sign informed consent forms.
In this study, patients will be randomly assigned to the experimental group and the control group in a 2:1 ratio according to a random allocation table. The table will be formulated on the basis of the random numbers generated by SPSS.
The study will comprise of three parts:
- Baseline - two weeks of run-in and screening period.
- Ensure that each patient reads and signs informed consent.
- Collect demographic data.
- Ask about past medical history, current medical history, surgical history, allergy history, etc.
- Ask about previous medication and combination medication.
- Complete the FFQ questionnaire.
- Collect information about vital signs, physical examination, BMI, ECG, conventional index and therapeutic effect index.
- Collect 2 tubes of stool samples for fecal metagenomics sequencing and three tubes of blood samples for measuring serum metabolomics and inflammatory index (IL-6).
- Review whether patients qualify for participate in the study according to the inclusion and exclusion criteria.
- Dietitian will give diet, exercise lifestyle intervention guidance to patients.
- FMT/ placebo intervention-patients will receive three interventions every two weeks.
