Probiotics Therapy of Mood Disorders

Status Completed

Clinical Trial Summary

The evaluation of the influence of a probiotics therapy on mood improvement and the reduction of depressive symptoms in women in the perimenopausal age group.

Clinical Trial Description

The aim: The evaluation of the influence of a probiotics therapy on mood improvement and the reduction of depressive symptoms in women in the perimenopausal age group. The study hypothesis: By using periodic probiotics therapy it is possible to positively influence the mood of women with depressive syndromes. These efforts focus on the improvement of the functioning of the gut barrier and gut-brain axis. In practice, such activities should lead to the reduction in the dysfunction of the barrier, the reduction of endotoxemia and the concentration of neurotoxic metabolites of tryptophan (in blood) with the simultaneous increase in the content of butyric acid that has a neuroprotective effect. The of the trial: intervention, cohort, randomized, double-blind, using placebo. A multi-strain probiotic will also be provided ( Bifidobacterium bifidum W23, Bifidobacterium lactis W52, Lactobacillus acidophilus W37, Lactobacillus brevis W63, Lactobacillus casei W56, Lactobacillus salivarius W24, Lactococcus lactis W19 and Lactococcus lactis W58 or maize starch, maltodextrins and vegetable protein/placebo). The applied method of study: 1. a controlled dietary intervention that includes probiotics therapy; the verification of the past nutritional pattern (the Food Frequency Questionnaire); anthropometric measurements; 2. psychiatric studies: the evaluation of sleep disorders (the Athens insomnia scale) and mood (the Beck scale), and the worsening of depression (the Hamilton scale); 3. biochemical studies: the content of short chain fatty acids (in the stool); 4. cytometric studies (B-type lymphocytes' panel, T-type lymphocytes' panel, regulatory T cells' panel); 5. genetic (the microbiome of bacteria in the stool, pyrosequencing); 6. chromatographic (the derivatives of tryptophan e.g., kynurenine, anthranilic acid, kynureic acid, 3-hydroxykynurenine, 5-hydroxytryptophan, serotonin). Currently, there is an urgent problem to develop recommendations regarding the nutrition and probiotics therapy that could complement the therapy of women with mood disorders. If the achieved results confirm the study hypothesis, it will be possible to: 1. better understand the pathomechanism of mood disorders in the perimenopausal period; 2. develop a holistic strategy for depressive disorders in women in the menopause period. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
