Clinical Evaluation of the Antidepressant Effect of the Use of Probiotics in Bipolar Disorder and Possible Mediating Effects of Systemic and Intestinal Inflammatory Markers in the Microbiota
In Brief
A clinical study evaluating Probiotic Group and Placebo Group for Bipolar Disorder. Completed, enrolled 141 participants across 1 site.
Detailed Summary
Bipolar Disorder (BD) is highly incapacitating and associated with premature mortality. Depressive symptoms and episodes are the most frequent cause of disability in subjects with BD and over half of patients do not respond adequately to approved treatments for this condition, showing the need for new classes of treatments to complement current pharmacotherapy. Previous studies demonstrated that the intestinal flora have potential positive or negative effects on the Central Nervous System and suggest that adding specific strains of bacteria to people's diet may have antidepressant properties.The study proposes to evaluate the clinical benefit of adding probiotics to pharmacological treatments for bipolar depression. This will be a study with 124 subjects (62 receiving probiotics and 62 placebo). The research team in this department has focused especially on non-pharmacological treatments for bipolar disorder (psychotherapy, nutrition and exercise) and is multidisciplinary in scope with psychiatrists, psychologists, nurses, physiotherapists and nutritionists participating in research projects.

Timeline
Interventions
The 124 participants will participate in a randomized, double-blind, placebo-controlled trial in two arms. The probiotic group will consist of 62 patients. These patients will be recruited from the USP Bipolar Disorder Program. This program has an outpatient clinic that offers free medical care to a population of different ethnic groups, with the majority of subjects coming from the middle and lower social classes.
