Arm Label
Probiotic
Placebo
Arm Description
Formula probiotic contains freeze-dried Lactobacillus casei, Bafidobacterium animals, Bifidobacterium longum, Bifidobacterium bidium and Lactobacillus plantarum, each at a dosage of 3.0E+10 CFU per 2g sachet.
Placebo made with only the excipients. The placebo sachet was matched to the study probiotic products for taste, color, and size.
Outcomes
Primary Outcome Measures
Hamilton Depression Rating Scale
Depressive symptoms as measured with the Hamilton Rating Scale for Depression. The score rangs from 0 to 53. The higher score means severer depressive symptoms.
Secondary Outcome Measures
Fecal microbiome
changes in the profile of gut microbiota before and after 8-week intervention.
Serum Il-1β
Serum Il-1β levels before and after intervention assessed by ELISA.
Serum Il-6
Serum Il-6 levels before and after intervention assessed by ELISA.
Serum TNF-α
Serum TNF-α levels before and after intervention assessed by ELISA.
Serum cortisol
Serum cortisol levels before and after intervention assessed by ELISA.
Serum Brain-derived neurotrophic factor
Serum Brain-derived neurotrophic factor levels before and after intervention assessed by ELISA.

5. Study Description
Brief Summary
Depressive disorder, also known as depression, is a type of mood disorder characterized by persistent low mood. The incidence of depression worldwide is about 6%. Growing evidence suggested that the gut microbiota plays a key role in the development of depression. Probiotics can effectively regulate gut microbiota, and showed potential in alleviating depression. This study investigated the effect of formula probiotic (containing Lactobacillus paracasei, Bifidobacterium animalis, Bifidobacterium longum, Bifidobacterium bifidum and Lactobacillus plantarum) on depression.
