Effect of Bacillus Coagulans and Galactomannans on Obese Patients Undergoing Sleeve Gastrectomy

September 21, 2021 updated by: Keith Scharf, DO, Loma Linda University
The purpose of the study is to determine the effect of bacillus coagulans and galactomannans (LactoWise®) administration on obese patients undergoing sleeve gastrectomy by observing standard protocol measurements in patients following sleeve gastrectomy: laboratory measurements, ideal body weight, and percent estimated weight loss, in addition incorporating the Gastrointestinal Quality of Life Index (GIQLI)

Detailed Description

Loma Linda University's School of Allied Health Professions in collaboration with the Metabolic and Bariatric Surgery Department under the Surgery Division is conducting research to evaluate the influence of LactoWise® (a proprietary blend of probiotic and prebiotic - bacillus coagulans/galactomannans, respectively) on the normal microbiota of obese patients post bariatric sleeve gastrectomy. Pre-surgery, participants will be required to sign a consent form and to complete the Gastro-Intestinal Quality of Life Index (GIQLI). A total of 60 bariatric sleeve patients will be recruited for this investigation. Post-surgery participants will be randomized into two groups, one will receive LactoWise® and one be the control (placebo). The LactoWise® blend has 300 mg of the bacillus coagulans and galactomannans and contains around 4.5 billion live cells. Daily intake of capsules coupled with bariatric sleeve standard of care will be conducted for the duration of 3 months, which is the anticipated clinical timeline. Participants will also be asked to complete the quality of life questionnaire at each of the following follow-ups post-surgery: 2nd week, 6th week, and 3rd month.

Outcome measures will be the standard protocol for bariatric sleeve patients at the Metabolic and Bariatric Surgery Department which will include weight measurements, blood work. In addition to the standard of care procedures a research procedure to be added is the GIQLI. Pre and post clinical consults, administration of probiotic/prebiotic formulae, and follow-ups will be conducted at the Faculty Medical Offices - General Surgery - Bariatric Clinic at Loma Linda University Health.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Proprietary Blend - LactoWise®
After being randomized into two groups, the assigned experimental group, prior to surgery and after consenting, will be asked to complete the Gastrointestinal Quality of Life Index. In addition the experimental group will be given their supply of LactoWise®. They will be required to take 1 capsule per day (300 mg of bacillus coagulans and galactomannans at 4.5 billion live cells) at breakfast consistently for 3 months. There will be three follow up visits (Week-2, Week-6 and Month-3) where participants will be asked to complete the gastrointestinal quality of life index.
Dietary supplement: LactoWise®
blend of bacillus coagulans and galactomannans
Other Names:
  • blend of bacillus coagulans and galactomannans
Placebo Comparator: Control
For the control group, prior to surgery and after consenting to enroll in the study participants will also be asked to complete the Gastrointestinal Quality of Life Index. Participants of the control group will be administered their supply of a matching placebo. They will be required to take 1 capsule per day at breakfast consistently for 3 months. There will be three follow up visits (Week-2, Week-6 and Month-3) where participants will be asked to complete the gastrointestinal quality of life index.
Other: Placebo
Placebo to be selected is calcium carbonate (since participant routine standard of care already includes intake of calcium citrate)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in weight percent EWL
Time Frame: Baseline - 3 months
Changes in weight expressed will be based off of the percent excess body weight loss (percentage EBWL) which is the weight loss relative to ideal weight expressed as a percentage. For the calculation of percentage EBWL the ideal body weight will be based off of BMI 25. BMI will be measured in kg/m^2. Studies have shown that changes in the physical structure or manipulation of the gastrointestinal system may influence normal microbiota which can be characterized by changes in metabolism which in turn will be tested by changes in weight
Baseline - 3 months
