FMT Capsules in Treatment of Patients With Insomnia Clinical Research

Not Applicable

• Conditions: Chronic Insomnia
• Interventions: Drug: FMT capsule

• Registration Number: NCT05427331
• Lead Sponsor: Third Military Medical University

Brief Summary

Objective: To investigate whether Fecal Microbiota Transplantation(FMT) can improve sleep in patients with insomnia, its effect on gut microbiota and its metabolites, and its effect on inflammatory factors, neurotransmitters and sex hormones in peripheral blood. Methods: The study needs to recruit 60 patients with insomnia and randomly divide them into FMT capsule treatment group or Placebo treatment group. The patients were followed up before the treatment and 4, 8, and 12 weeks after the treatment. The sleep status of the patients was assessed by Pittsburgh sleep quality index-PSQI, and the changes of gut microbiota and its metabolites were detected by Metagenomic sequencing and metabonomics analysis.The expression of cytokines, sex hormones and neurotransmitters in peripheral blood were detected by Elisa.

Detailed Description

Insomnia is increasingly common in modern society. In recent years, more and more studies have shown that compared with healthy people, insomnia patients have changes in gut microbiota and its metabolites. At the same time, gut microbiota, as an important part of the gastrointestinal tract, can affect the stability of the body's internal environment through a variety of ways through the "microbial-gut-brain axis", including the regulation of immune response. However, relevant studies at home and abroad mainly focus on sleep deprivation, while there are few reports on the intervention of gut microbiota in insomnia. The purpose of this study was to investigate whether Fecal Microbiota Transplantation(FMT) can improve sleep in patients with insomnia, its effect on gut microbiota and its metabolites,and its effect on inflammatory factors, neurotransmitters and sex hormones in peripheral blood. The study needs to recruit 60 patients with insomnia and randomly divide them into FMT capsule treatment group or Placebo treatment group. The patients were followed up before the treatment and 4, 8, and 12 weeks after the treatment. The sleep status of the patients was assessed by Pittsburgh sleep quality index-PSQI, and the changes of gut microbiota and its metabolites were detected by Metagenomic sequencing and metabonomics analysis.The expression of cytokines, sex hormones and neurotransmitters in peripheral blood were detected by Elisa.
