Effect of Probiotic on Comorbidity of Depression and Constipation
September 25, 2020 updated by: Fazheng Ren, China Agricultural University
Effect of Probiotic on Chinese Patients With Depression and Constipated Comorbidity
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%.
The high comorbidity rate between depression and constipation indicated the role of the gut-brain axis in depression.
Growing evidence suggested that the gut microbiota plays a key role in the development of depression.
Probiotics can effectively improve constipation and regulate gut microbiota, and showed potential in alleviating depression.
This study investigated the effect of formula probiotic (containing Lactobacillus paracasei, Bifidobacterium animals, Bifidobacterium longum, Bifidobacterium bifidum, and Lactobacillus plantarum) on the comorbidity of depression and constipation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Placebo
Placebo made with only the excipients.
The placebo sachet was matched to the study probiotic products for taste, color, and size.
|
Patients receive the placebo identical to probiotic for consecutive 8 weeks ( one sachet per day ).
|
Experimental: Probiotic
Formula probiotic contains freeze-dried Lactobacillus paracasei, Bifidobacterium animals, Bifidobacterium longum, Bifidobacterium bifidum, and Lactobacillus plantarum, each at a dosage of 3.0 × 10^10 colony forming unit per 2g sachet.
|
Patients receive the formula probiotic for consecutive 8 weeks ( one sachet per day ).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hamilton Depression Rating Scale
Time Frame: Change from baseline score to intervention measurements at 4 and 8 weeks
|
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.
|
Change from baseline score to intervention measurements at 4 and 8 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Patient Assessment of Constipation Symptom
Time Frame: changes from baseline score to intervention measurements at 4 and 8 weeks
|
Constipation symptoms as measured with the Patient Assessment of Constipation Symptom.
The score ranges from 0 to 48.
The higher score means severer constipated symptoms.
|
changes from baseline score to intervention measurements at 4 and 8 weeks
|
Serum Il-1β
Time Frame: changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum Il-1β levels before and after intervention assessed by ELISA.
|
changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum Il-6
Time Frame: changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum Il-6 levels before and after intervention assessed by ELISA.
|
changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum TNF-α
Time Frame: changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum TNF-α levels before and after intervention assessed by ELISA.
|
changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum cortisol
Time Frame: changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum cortisol levels before and after intervention assessed by ELISA.
|
changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum Brain-derived neurotrophic factor
Time Frame: changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum Brain-derived neurotrophic factor levels before and after intervention assessed by ELISA.
|
changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum concentrations of tryptophan metabolites
Time Frame: Changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum concentrations of tryptophan metabolites quantified by High-Performance Liquid Chromatography and Mass Spectrometry
|
Changes from baseline level to intervention measurements at 4 and 8 weeks
|
Serum concentrations of bile acid
Time Frame: Changes from baseline level to intervention measurements at 4 and 8 weeks
|
Quantification by High-Performance Liquid Chromatography and Mass Spectrometry
|
Changes from baseline level to intervention measurements at 4 and 8 weeks
|
Fecal microbiome
Time Frame: Changes from baseline to intervention measurements at 4 and 8 weeks
|
Fecal microbiome measured by next generation sequencing
|
Changes from baseline to intervention measurements at 4 and 8 weeks
|
Stool form
Time Frame: Change from baseline score to intervention measurements at 4 and 8 weeks
|
Stool form measured with the Bristol Stool Form Scale, which classify the form of human faeces into seven types, successively named type 1 to type 7. Types 1 and 2 indicate constipation, with 3 and 4 being the ideal stools as they are easy to defecate while not containing excess liquid, 5 indicating lack of dietary fiber, and 6 and 7 indicate diarrhoea.
