Evaluation of the Efficacy and Safety of Fecal Microbiota Transplantation for Parkinson's Disease Patients With Constipation

Обзор

Participants will be allocated to FMT group or placebo group at a 1:1 ratio. For interventional group, patients will be given six FMT capsules twice a week for 24 weeks. Placebo capsules are identical in appearance and smell but contain milk powder. At each follow-up visits, participants complete specific scales to assess improvement in constipation, emotion and quality of life. Besides, fecal samples are collected for metagenomics and metabolomics sequencing and blood samples are tested peripheral concentration of levodopa.

Подробное описание

This prospective, double-blind, randomised, placebo-controlled study aims to evaluate efficacy and safety of fecal microbiota transplantation for constipation in Parkinson's disease. Participants will be given either FMT capsules or placebo capsules at a ratio of 1:1. For experimental group, patients will be given six FMT capsules twice a week for 24 weeks. Placebo capsules are identical in appearance and smell but contain milk powder. After 24-week treatment, participants complete specific scales to assess improvement in constipation, other PD symptoms, emotion and quality of life. Besides, fecal samples are collected for metagenomics and metabolomics sequencing and blood samples are tested peripheral concentration of levodopa.

Вмешательства

• Препарат Healthy donor-derived FMT capsule
  Participants will be treated with healthy donor-derived fecal microbiota transplantation in the form of oral capsules.
• Препарат Placebo capsule
  Capsules whose appearance and smell are identical as FMT capsules but contain milk powder
