Trial 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%. The high comorbidity rate between depression and constipation indicated the role of the gut-brain axis in depression. Read more about this study

About this study

Official title: 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ProbioticDietary supplement

    Patients receive the formula probiotic for consecutive 8 weeks ( one sachet per day ).

  • PlaceboDietary supplement

    Patients receive the placebo identical to probiotic for consecutive 8 weeks ( one sachet per day ).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Change from baseline score to intervention measurements at 4 and 8 weeks

Secondary outcomes (10)
  1. Patient Assessment of Constipation Symptom

    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.

    Measured: changes from baseline score to intervention measurements at 4 and 8 weeks

  2. Serum Il-1β

    Serum Il-1β levels before and after intervention assessed by ELISA.

    Measured: changes from baseline level to intervention measurements at 4 and 8 weeks

  3. Serum Il-6

    Serum Il-6 levels before and after intervention assessed by ELISA.

    Measured: changes from baseline level to intervention measurements at 4 and 8 weeks

  4. Serum TNF-α

    Serum TNF-α levels before and after intervention assessed by ELISA.

    Measured: changes from baseline level to intervention measurements at 4 and 8 weeks

  5. Serum cortisol

    Serum cortisol levels before and after intervention assessed by ELISA.

    Measured: changes from baseline level to intervention measurements at 4 and 8 weeks

  6. Serum Brain-derived neurotrophic factor

    Serum Brain-derived neurotrophic factor levels before and after intervention assessed by ELISA.

    Measured: changes from baseline level to intervention measurements at 4 and 8 weeks

  7. Serum concentrations of tryptophan metabolites

    Serum concentrations of tryptophan metabolites quantified by High-Performance Liquid Chromatography and Mass Spectrometry

    Measured: Changes from baseline level to intervention measurements at 4 and 8 weeks

  8. Serum concentrations of bile acid

    Quantification by High-Performance Liquid Chromatography and Mass Spectrometry

    Measured: Changes from baseline level to intervention measurements at 4 and 8 weeks

  9. Fecal microbiome

    Fecal microbiome measured by next generation sequencing

    Measured: Changes from baseline to intervention measurements at 4 and 8 weeks

  10. Stool form

    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.

    Measured: Change from baseline score to intervention measurements at 4 and 8 weeks
