Probiotic Milk Drink for Gut and Brain Health in Older Adults and Caregivers

Not Yet RecruitingNA

Sponsor: University of South Florida

Conditions: Alzheimer Disease Related Dementia

Interventions: Probiotic Fermented Milk (PFM) Drink, Placebo

Countries: United States

This double-blind, randomized, placebo-controlled clinical trial will evaluate the effects of a probiotic fermented milk (PFM) drink on gut and brain health in individuals with Alzheimer's disease and related dementias (ADRD) and their caregivers. Up to 40 participants will be enrolled. Participants will be randomly assigned to consume either the PFM drink or a matched placebo daily for 30 days. The primary objective is to determine whether PFM consumption improves gut microbiome abnormalities. Secondary objectives include evaluating effects on nutrient absorption, gut microbiome diversity and composition, and systemic inflammation. The study will also explore relationships between changes in nutrient absorption, microbiome profiles, inflammation, and behavioral outcomes in participants with ADRD and their caregivers. Each participant will participate in the study for approximately 30 days. This pilot study is intended to generate preliminary clinical and biological data regarding the potential role of probiotic nutrition in supporting gut and brain health and to inform the design of future larger clinical trials.

Eligibility criteria

* Known allergy, intolerance, or hypersensitivity to Ensure® or any of its components.
* Cancer patients receiving chemotherapy, due to potential increased risk of infection from GI tract damage
* Participants who require systemic antibiotics after randomization will have the antibiotic use documented and will be withdrawn due to potential effects on the gut microbiome. Data collected prior to antibiotic use may be retained, and withdrawn participants will be replaced to maintain the target sample size.
* Major surgery(ies) of the gut or brain within the past five years
* Diagnosis of inflammatory bowel disease (IBD), ulcerative colitis, Crohn's disease, acid reflux, gastroesophageal reflux disease (GERD), Clostridium difficile infection (CDI), or any other gastrointestinal disease that could significantly change the microbiome History of fecal microbiota transplantation
* Small intestinal bacterial overgrowth
* History of anticipatory nausea, vomiting, constipation, or diarrhea
* Antibiotic or probiotic or heavy yogurt (3 servings per day) use within the past 30 days

  o Probiotic use is defined as consumption of ≥108 CFU/day, in the form of tablets, capsules, lozenges, powders, or dairy products in which probiotics are a major ingredient
* Critical or terminal illnesses including diabetes
* Pregnant women will be excluded from the study based on self-report during the screening process. No pregnancy testing kits will be provided, and pregnancy testing will not be performed as part of this study. Therefore, individuals who are currently pregnant are excluded from participation.
