Probiotic Supplementation and Pancreatic β-Cell Function in Type 2 Diabetes

Obesity Clinical Trial

Official title: Efficacy and Safety of Multi-strain Probiotic on Pancreatic β-cell Function in Type 2 Diabetes Patients

Status Completed

Clinical Trial Summary

Probiotics have beneficial effect on obesity related disorders in animal models. Current understanding for the beneficial effects of probiotics in type 2 diabetes strictly relies on animal and clinical data, which mainly focus on their impact on insulin resistance, anthropometric parameters, glycemic control and markers of chronic systemic inflammation. From the other hand, there is a lack of evidence-based probiotic efficacy on pancreatic β-cell function in terms of type 2 diabetes and related metabolic disorders. In this double-blind single center randomized clinical trial, effect of alive multistrain probiotic vs. placebo on pancreatic β-cell function in type 2 diabetes patient will be assessed.

Clinical Trial Description

In this single-center double blind, placebo controlled, parallel group study, type 2 diabetes patients from the Kyiv City Clinical Endocrinology Center will be selected. They will be randomly assigned to receive multiprobiotic "Symbiter" or placebo for 8-weeks administered as a sachet formulation in double-blind treatment. Randomization will be done by the study statistician based on a computer-generated list. The groups will be homogeneous according to age, sex and diagnostic criteria. The assignment of groups will be blind to participants, research staff and outcome assessors moreover, to maintain blind parallel study the statistician was not aware of the allocation of participants to intervention.

The multiprobiotic "Symbiter" will be supplied by Scientific and Production Company "O.D. Prolisok". It contains of 14 alive probiotic strains of Lactobacillus + Lactococcus (6×1010 CFU/g), Bifidobacterium (1×1010/g), Propionibacterium (3×1010/g), Acetobacter (1×106/g) genera. Over 8 weeks of interventional period, the patient received 1 sachet (10 grams) of probiotic and placebo per day. All sachets were identical with similar organoleptic characteristics (e.g., taste and appearance).

The pre-randomization period designed to minimize the effects of dietary changes on metabolic markers. For this purpose, 2 weeks before the study start, after inform consent signed, patients will be instructed in one-on-one sessions with a dietitian to follow a therapeutic lifestyle-change diet as classified by the NCEP. In addition, participants will be instructed to continue with stable anti-hyperglycemic treatment and received standardized mild physical training for 1 hour per day.

Patients who underwent study will be instructed to take the trial medication as prescribed. Throughout the study, weekly phone follow-up visits will be provided for assessment of compliance, adherence to the protocol, as well as the recording of adverse events. The effectiveness of therapy will be compared and evaluated separately in the two groups. ;
