Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to identify the variations in gut microbiota compositions between two subtypes of major depressive disorder.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective: To identify the variations in gut microbiota compositions between two subtypes of major depressive disorder (MDD), namely those with and without REM sleep behavior disorder (RBD). To correlate the microbiota composition with depressive severity and prodromal markers of α-synucleinopathy.

Design: Case-control study Setting: Established clinical cohorts consisting of patients with comorbid MDD+RBD and MDD only and a group of sexand age-matched healthy control Participants: Patients with comorbid MDD+RBD (n=55), patients with MDD only (n=55), and healthy control (n=55).

Main outcome measures: The abundance and composition of gut microbiota, severity of depressive symptoms, and prodromal markers of α-synucleinopathy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

MDD + RBD

1. Clinical diagnosis of lifetime major depressive disorder, based on the M.I.N.I.;
2. RBD diagnosis according to the International classification of sleep disorder (ICSD) 3rd edition, fulfilling both the clinical and video-polysomnography (vPSG) criteria;
3. Depressive symptoms onset before RBD onset

No intervention

Intervention Type OTHER

No intervention

MDD

1. Age-and sex-matched with MDD+RBD probands;
2. Lifetime diagnosis of MDD based on M.I.N.I.;
3. Without a personal history or a family history of RBD or neurodegenerative diseases (i.e. dementia and PD)
4. Free of RBD symptoms or other hallmark features of RBD (e.g. REM Sleep Without Atonia, RWSA) by vPSG

No intervention

Intervention Type OTHER

No intervention

Health control

1. Age-and sex-matched with MDD+RBD subjects;
2. Free of psychiatric disorders based on M.I.N.I.;
3. Without a personal history or a family history of RBD or neurodegenerative diseases (i.e. dementia and PD)
4. Free of RBD symptoms or RWSA by vPSG

No intervention

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age-and sex-matched with MDD+RBD subjects;
2. Free of psychiatric disorders based on M.I.N.I.;
3. Without a personal history or a family history of RBD or neurodegenerative diseases (i.e. dementia and PD)
4. Free of RBD symptoms or RWSA by vPSG

Exclusion Criteria

1. Presence of narcolepsy and other neurodegenerative diseases that may give rise to RBD and RWSA;
2. Severe psychiatric illness that could not permit a valid written informed consent or otherwise is not suitable for participating in a study;
3. Use of antibiotics within one month and the use of probiotics within three days prior to sample collection;
4. Pre-existing or post-operation of gastrointestinal diseases (e.g. inflammatory bowel disease, gastrointestinal cancer).
