简要总结
This study aims to explore the efficacy and safety of a synbiotic formula (MQU10) in improving mood and well-being in adults with mild to moderate depressive symptoms.
详细描述
Major depression disorder (MDD) affects up to 20% of the population. In Hong Kong, one in seven suffered from mental health disorders with depressive disorder being one of the most frequent diagnoses. Depression is characterized by persistently low mood and loss of interest, possibly resulting from multifactorial factors including brain chemical abnormalities, genetics, stress, trauma and medical conditions. Current treatments for depression mainly include medication that alters neurotransmission in the brain and cognitive behavioural therapy to change cognitive distortions and their associated behaviours. However, there are side effects associated with the use of antidepressant medications as well as perceived stigma in receiving antidepressants and the uptake and accessibility of psychotherapy is extremely low. Thus, alternative therapeutic options are therefore needed to manage depression and its associated symptoms.
Emerging evidence suggests the important role of gut microbiota and gut-brain axis in mood regulation. In particular, there is high comorbidity among individuals with depression and gastrointestinal conditions such as irritable bowel syndrome and inflammatory bowel disease. There is also evidence suggesting that gut microbiota could produce metabolites and compounds with neuroactive and immunomodulatory properties. Previous studies have also supported the association between the dysbiosis of gut microbiota and affective disorders. Clinical trials on the use of microbiome-based therapeutics showed some efficacy in improving depression and insomnia. Gut microbiota modulation could be a novel therapeutic strategy for improving mood problems.
This pilot, single-arm study aims to explore the efficacy and safety of a synbiotic formula (MQU10), which is composed of food-grade probiotic strains and prebiotic compounds, in improving mood and well-being in adults with mild to moderate depressive symptoms.

研究组 & 干预措施
MQU10
Subjects will take 1 sachet of synbiotics formula (MQU10) daily for 6 weeks
干预措施: MQU10 (Dietary Supplement)
结局指标
主要结局
Proportions of subjects with improvement in condition, assessed by the Clinical Global Impression - Global Improvement Scale (CGI-I) at 6 weeks
时间窗: 6 weeks
The improvement in condition will be assessed by the Clinical Global Impression - Global Improvement Scale (CGI-I) at 6 weeks. It is a 7-point Likert scale. The clinician investigator will rate the improvement as 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse.
次要结局
- Changes in depression level, assessed by Patient Health Questionnaire-9 (PHQ-9) by 6 weeks(6 weeks)
- Self-report improvement in condition, assessed by Patient Global Impression of Change scale (PGI-C) by 6 weeks(6 weeks)
- Changes in anxiety level, assessed by Generalised Anxiety Disorder 7-item scale (GAD-7) by 6 weeks(6 weeks)
- Changes in health-related quality of life, assessed by World Health Organization Quality of Life-BREF (WHOQOL-BREF) by 6 weeks(6 weeks)
- Changes in gut microbiota composition and functions by 6 weeks(6 weeks)
- Adverse events by 6 weeks(6 weeks)
