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%. 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.

Outcome Measures

Primary Outcomes (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.

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

Secondary Outcomes (10)

  • Patient Assessment of Constipation Symptom

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

  • Serum Il-1β

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

  • Serum Il-6

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

  • Serum TNF-α

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

  • Serum cortisol

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

  • +5 more secondary outcomes

Study Arms (2)

Probiotic

EXPERIMENTAL

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.

Dietary Supplement: Probiotic
