Clinical Trial Summary

This study is a multicenter randomized double-blind placebo-controlled study. The research content is 1. The improvement effect of Bifidobacterium triple viable capsules（BIFICO） on motor symptoms and constipation and sleep in mild to moderate Parkinson's disease and the safety of the study; 2. the mechanism of the improvement effect of intestinal microecological changes on motor and constipation symptoms in mild to moderate Parkinson's disease.

Description:

This was a multicenter randomized double-blind placebo-controlled study that included 240 patients with primary PD with modified H-Y stage 1-3, randomly divided into treatment and placebo control groups; On the basis of the original PD medication, the treatment group was given bifidobacterium triple viable capsules (BIFICO) and the control group was given placebo; Patients who met the diagnosis of constipation were given Macrogol 4000 powder and /or Enema glycerine as a rescue medicine, and the observation period was 12+12 weeks.

All subjects underwent the World Movement Disorders Society Parkinson's Disease Comprehensive Rating Scale (MDS-UPDRS), Rome IV Constipation Diagnostic Scale, Cleveland Rating Scale, Parkinson's Disease Sleep Scale-2 (PDSS-2), and General Clinical Outcome Inventory (CGI) scores before and after treatment, and also recorded the patients' single bowel movement time and the use of Macrogol 4000 powder and Enema glycerine , to investigate the improvement effect of Bifido on motor symptoms and non-motor symptoms in PD patients. For the above patients, stool and blood samples were collected at the time of enrollment and at 12 weeks of observation.

At the same time,120 age-and gender-matched healthy adults without constipation were recruited, and their stool and blood samples were collected; the stool samples of PD patients before and after treatment and healthy controls were subjected to the determination of fecal flora 16S DNA abundance. Stool samples of 10 PD patients and 10 healthy controls were taken from each group for metagenomic sequencing. Detection of small molecule metabolites, PD-related genes in blood. To investigate the effect of BIFICO on levodopa pharmacokinetics, levodopa pharmacokinetic measurements will be performed at Friendship Hospital. For patients who agree to participate and sign the informed consent form, blood specimens will be collected consecutively at Visit 2 and Visit 11 after taking Levodopa and Benserazide Hydrochloride Tablets for levodopa blood concentration measurement.
