Experimental: Probiotic Supplement
The probiotic supplement will consist of capsules containing approximately 1 billion (1.0 x 10^9) colony forming units of the probiotic organisms, Lactobacillus rhamnosus LGG® (LGG®) and Bifidobacterium animalis subsp. lactis BB-12® (BB-12®). The capsule, which will be swallowed, is a size 3 opaque, hard, hypromellose capsule. Participants will be asked to take 1 capsule of the probiotic supplement with a meal or with a snack daily for 24 weeks.
Biological: Probiotic Supplement
Probiotic supplement 1 tablet by mouth daily
Other Name: Probio-Tec® BG-VCap-6.5
Placebo Comparator: Inert Compound
The inert compound placebo looks identical to the probiotic supplement, and participants will be instructed to swallow 1 capsule with a meal or with a snack daily for 24 weeks.
Biological: Inert Compound
Probiotic identical placebo 1 tablet by mouth daily
- Time to Relapse [ Time Frame: Weeks 0 - 24 of study participation ]Time to relapse defined as time until psychiatric rehospitalization during the study period
- New Mood Episodes [ Time Frame: Weeks 0 - 24 of study participation ]Number of new mood episodes determined by Structured Clinical Interview for DSM-5 Disorders (SCID-5), an interview using criteria from the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5)
- Brief Psychiatric Rating Scale [ Time Frame: Weeks 0 - 24 of study participation ]The Brief Psychiatric Rating Scale (BPRS) will be used to measure the severity of psychiatric symptoms. The BPRS contains 24 items, each rated on a scale from 1 (not present) to 7 (very severe). Total scores range from 24 to 168, and high scores indicate increased symptomatology.
- Young Mania Rating Scale [ Time Frame: Weeks 0 - 24 of study participation ]The Young Mania Rating Scale (YMRS) will be used to measure mania-related symptoms. The YMRS contains 11 items, each rated either on a scale from 0 to 4 or a scale from 0 to 8. Total scores range from 0 to 60, and higher scores indicate increased mania-related symptomatology.
- Montgomery-Åsberg Depression Rating Scale (MADRS) [ Time Frame: Weeks 0 - 24 of study participation ]The Montgomery-Åsberg Depression Rating Scale (MADRS) will be used to measure depression-related symptoms. The MADRS contains 10 items, each rated on a scale from 0 (none or normal) to 6 (most severe). Total scores range from 0 to 60, and higher scores indicate increased depression-related symptomatology.
- Hamilton Depression Rating Scale [ Time Frame: Weeks 0 - 24 of study participation ]The Hamilton Depression Rating Scale (HAM-D) will be used to measure depression-related symptoms. The HAM-D contains 24 items, each rated either on a scale from 0 to 2 or on a scale from 0 to 4. Total scores range from 0 to 76, and higher scores indicate increased depression-related symptomatology.
- Columbia-Suicide Severity Rating Scale [ Time Frame: Weeks 0 - 24 of study participation ]The Columbia-Suicide Severity Rating Scale (C-SSRS) measures suicide attempts and ideation. The C-SSRS is a tool containing one section of items used for assessing the specific type and intensity of suicidal ideation and one section of items used to determine number and type of suicide attempts and actual or potential lethality of the most lethal suicide attempt. The number of items used depends upon participant responses, and higher ratings on specific items indicate either more attempts, more intense ideation, or more lethal behavior. The C-SSRS will be used to determine the occurrence of suicide attempts or ideation.
- Intestinal Inflammation [ Time Frame: Baseline, Week 12, Week 24 ]Levels of intestinal inflammation as measured by antibodies to casein, gliadin and saccharomyces cerevisiae as well as C-reactive protein (CRP) and cytokines
