Bacillus coagulans (PROBACI) supplementation significantly improved functional bowel disorder symptoms like abdominal pain and distention. PROBACI also led to less discomfort and more normalized bowel movements, particularly in constipation-dominant patients.
Area of Science:
- Microbiology
- Gastroenterology
- Human Microbiome
Background:
- Functional bowel disorders (FBDs) affect a significant portion of the population, causing debilitating symptoms.
- Probiotics, such as Bacillus coagulans, are increasingly explored for their potential to modulate gut health and alleviate FBD symptoms.
- Existing research on Bacillus coagulans efficacy in FBDs requires further elucidation, particularly concerning specific symptom profiles.
Purpose of the Study:
- To evaluate the therapeutic effects of Bacillus coagulans (PROBACI) on a range of functional bowel symptoms in patients with FBDs.
- To assess the impact of PROBACI on abdominal pain, distention, defecation characteristics, and overall patient assessment.
- To analyze changes in gut microbiota composition, specifically the Firmicutes/Bacteroidetes ratio, following PROBACI administration.
Main Methods:
- An observational, cross-sectional study involving 38 patients diagnosed with functional bowel disorders.
- Patients received a 300-mg formulation of PROBACI (containing 1 × 10^9 CFU of B. coagulans) twice daily for 4 weeks.
- Symptom severity was measured using visual analog scales, and defecation patterns were recorded. Gut microbiota analysis was performed using 16S rRNA gene sequencing.
Main Results:
- Significant improvements were observed in abdominal pain (P=.0009), abdominal distention (P=.0002), and global assessment (P=.0001) within 14 days of PROBACI treatment.
- Patients in the constipation-dominant group showed greater improvements in defecation discomfort (P=.02) and normalization of defecation style (P=.007) compared to the diarrhea-dominant group by day 28.
- While a difference in the Firmicutes/Bacteroidetes ratio was noted between constipation- and diarrhea-dominant groups, it did not reach statistical significance.
Conclusions:
- Bacillus coagulans (PROBACI) effectively alleviates key symptoms associated with functional bowel disorders, including abdominal pain and distention.
- PROBACI demonstrates a notable benefit in improving defecation comfort and regularity, with enhanced efficacy observed in patients with constipation-predominant symptoms.
- The findings support the use of Bacillus coagulans as a potential therapeutic agent for managing functional bowel disorders, contributing to improved gut health and patient well-being.
