About this study

Official title: Multimodal Image Technologies Investigate the Role and Mechanism of Probiotics in Improving Rapid Eye Movement Behavior Disorder with Parkinson's Disease

Rapid eye movement sleep behavior disorder (RBD) is important non-movement feature, and also the important risk factor of Parkinson's disease (PD). In our previous work, we found that the movement features and RBD of PD patients improved after taking probiotics. The later was not reported before and the mechanism not clear. To investigate its role and mechanism, we plan to enroll patients of PD-RBD, idiopathic RBD, and healthy control, collect data of multimodal image technology before and after probiotic treatment，including resting state functional MRI，1H-MRS，123I-MIBG; analyze these data with clinical features, including UPDRS -III score, RBD-HK score , as well as the bacteria abundance and level of glutamate，GABA in blood and stool. Then, construct PD mouse model by fecal transplantation of PD patient, give or not give mouse probiotics treatment, and detect the level of glutamate, GABA, and so on, as well as α-synuclein of each brain area of each group, to explore the role and mechanism of probiotics in improving RBD and movement disorder of PD.

Read the detailed description

The primary objectives of this study are to explore the effects and mechanisms of probiotic intervention on improving REM sleep behavior disorder (RBD) in patients with Parkinson's disease (PD) from both clinical and animal experimental levels. The study aims to elucidate the scientific hypothesis that "probiotic intervention improves RBD in PD patients through a neuroendocrine mechanism," providing a theoretical basis for the mechanism by which probiotic intervention alleviates RBD symptoms in PD patients.

Research Content:

Establishing imaging detection technical processes and parameters for RBD.Collecting pre- and post-probiotic treatment imaging parameters and comparing them with RBD improvement to explore the mechanism by which probiotics improve PD patient RBD.Detecting fecal microbiota abundance and blood and fecal metabolite concentrations to discuss the biochemical mechanism by which probiotics improve PD motor symptoms and RBD.

Research Methods:

Patient Recruitment:

Enrolling PD-RBD, iRBD, and healthy control subjects, with specific inclusion and exclusion criteria based on clinical diagnosis and symptomatology.

Clinical Assessments and Tests:

Utilizing standardized scales such as RBDSQ, RBD-HK, UPDRS-III, and Hoehn-Yahr staging for symptom evaluation. Conducting polysomnography (PSG) for RBD diagnosis and exclusion of other sleep disorders.

Multimodal Imaging Data Collection:

Employing 3.0T MRI for high-precision anatomical imaging, resting-state functional MRI (rs-fMRI), and proton magnetic resonance spectroscopy (1H-MRS) for glutamate, GABA, and other metabolites in specific brain regions.

Performing 123I-MIBG cardiac scintigraphy to assess cardiac sympathetic nerve function.

Laboratory Tests:

Measuring concentrations of glutamate, GABA, acetylcholine, and other metabolites in blood and fecal samples. Assessing fecal microbiota abundance through 16S rRNA gene sequencing.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 23 inclusion and 34 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Houzhen Tuo Principal Investigator, PhD (+8613683628005, tuohouzhen@ccmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Magnetic resonance imaging changes of brain structure and function (time frame: 12 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06710574, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2024.
