Purpose
Background: The connection between gut health and diabetes status is increasingly recognized. Gut microbiota composition in diabetic differs from non-diabetic individuals. Interestingly, the level of glucose tolerance was associated with specific microbiota that was rarely found in healthy individuals. Probiotics is one of the functional foods believed to mediate their health promoting activities through modulating the composition of the gut health. Ingestion of probiotics has been shown not only to influence gut microbiota composition but also the secretion of the gut hormones and insulin resistance in animal models with limited trials in human. Supplementation with probiotic has also been shown not only affect glucose homeostasis, but improved other diabetes related comorbidities such as obesity, hypertension, and hyperlipidemia.
Objectives and hypotheses: To address this research gap, this Randomized Controlled Trial (RCT) is proposed to determine the efficacy of probiotic supplementations as adjuvant therapy to improve glucose homeostasis through modulating gut microbiota composition and gut hormones secretion in individuals with type 2 diabetes. We hypothesized that the probiotic supplementations will improve blood glucose control as well as other diabetes related co-morbidities in individuals with type 2 diabetes.
Methodology: This is a double blind randomized parallel group control trial with 3 months probiotic supplementation or placebo. After screening the eligible subjects will be selected. Then, after consent taking, subjects will be randomly assigned to either receive probiotic or supplement for 3 months. Measurements of blood parameters including glycemic control related parameters, lipid profile, renal profile, and liver function tests as well as three day diet recall, and anthropometry measurements will take place at baseline, after 6 weeks and after 12 months.
Expected Outcomes: Probiotic supplementation as an adjuvant therapy would improve glucose homeostasis and gut health as compared to the placebo and eventually will beneficially affect other diabetes related conditions. This study would provide avenue to identify the possibility of probiotic supplementations as an adjuvant therapy in the management of type 2 diabetes.
