A Study of the Efficacy of Fecal Microbiota Transplantation(FMT) in the Treatment of Depression
Study Details
Study Description
Brief Summary
Patients with depression were enrolled and randomly divided into two groups, namely FMT combined with antidepressant group and Antidepressant alone group.The former received FMT capsules and antidepressants, and the latter received oral placebo and antidepressants for an 8-week intervention.Before and after intervention, venous blood samples were collected from patients for routine tests such as liver and kidney function to judge the safety of treatment. At the same time, psychological scales were used to evaluate the improvement of patients' depressive symptoms, so as to judge the efficacy and safety of FMT combined with antidepressants.

Detailed Description
The main research content of this project is to observe the efficacy and safety of adjuvant FMT capsules in the treatment of depression by recruiting patients with first episode depression and randomly administering FMT combined with antidepressants or placebo combined with antidepressants.
In this study, patients with first episode depression were randomly divided into two groups. The first group was the experimental group, and FMT capsules (1012 colony forming unit(CFU)/ capsule) were used in addition to conventional antidepressant therapy. The other group, a control group, was given placebo capsules with the same color, look and smell as the FMT capsules in addition to regular antidepressant therapy. Placebo capsules contain Lactobacillus probiotics for food use (1012 CFU/ capsule). The changes of depressive symptoms and adverse reactions before and after treatment were observed in the two groups to explore the efficacy and safety of FMT capsule in the adjuvant treatment of depression.
The subjects (inpatients) were evaluated for meeting the eligibility requirements for this study according to the pre-specified inclusion and exclusion criteria, and demographic data (age, sex, marital status, educational level, employment, height and weight, smoking and drinking, and other general information as well as questionnaire assessment of eating habits) were collected. Improve laboratory examination (blood routine, liver function, kidney function and lipid), electrocardiogram and scale assessment.
Patients at the end of the screening period were randomly assigned to the experimental and control groups. Subjects will continue to receive FMT capsules or placebo capsules until the end of 8 weeks. During this period, both groups could use new selective serotonin reuptake inhibitors(SSRI)(fluoxetine, citalopram, escitalopram, Sertraline, paroxetine and fluvoxamine) recommended by current treatment guidelines, and the effective therapeutic dose of the drugs was added within 1 week. If, during the 8 weeks of the treatment period, the patient experienced significant fluctuations or severe adverse events that necessitates a change in antidepressant class, the study was terminated.
Benzodiazepines and medications that ameliorate side effects of antidepressants were allowed during the study period. Antipsychotics and mood stabilizers were prohibited. Electronic biofeedback therapy was allowed during the study, and transcranial magnetic stimulation and electroconvulsive non-convulsive therapy were prohibited.

| Experimental: Fecal microbiota transplantation(FMT) Subjects will receive FMT capsules (10^12 CFU/capsule) in addition to their usual antidepressant treatment. Subjects will continue to receive FMT capsules for 8 weeks. New SSRI antidepressants (fluoxetine, citalopram, escitalopram, sertraline, paroxetine, and fluvoxamine) recommended by current treatment guidelines can be used during this period, and the effective therapeutic dose of the drugs can be added within 1 week. |

| Placebo Comparator: Placebo Participants will receive a placebo capsule with the same color, appearance, and smell as the FMT capsule, in addition to their usual antidepressant treatment. Placebo capsules contained the food probiotic Lactobacillus (10^12 CFU per capsule). Subjects will continue to receive placebo capsules for 8 weeks. New SSRI antidepressants (fluoxetine, citalopram, escitalopram, sertraline, paroxetine, and fluvoxamine) recommended by current treatment guidelines can be used during this period, and the effective therapeutic dose of the drugs can be added within 1 week. |
Other: Placebo

Outcome Measures
Primary Outcome Measures
- Scores on the Hamilton Depression Scale (HAMD) [At the beginning of treatment]
Hamilton Depression Scale (HAMD) is the most commonly used scale in clinical depression assessment. This scale is evaluated by trained doctors, usually through conversation and observation, and scored after the examination. Score before and after treatment and during treatment can evaluate the severity of the disease and treatment effect.
- Scores on the Hamilton Depression Scale (HAMD) [At 4 weeks]
Hamilton Depression Scale (HAMD) is the most commonly used scale in clinical depression assessment. This scale is evaluated by trained doctors, usually through conversation and observation, and scored after the examination. Score before and after treatment and during treatment can evaluate the severity of the disease and treatment effect.
- Scores on the Hamilton Depression Scale (HAMD) [At the end of 8 weeks]
Hamilton Depression Scale (HAMD) is the most commonly used scale in clinical depression assessment. This scale is evaluated by trained doctors, usually through conversation and observation, and scored after the examination. Score before and after treatment and during treatment can evaluate the severity of the disease and treatment effect.
