Smectite Gel and Probiotic for Obesity and Insulin Resistance

Obesity Clinical Trial

Official title: Co-administration of Smectite Gel With Live Probiotic Strains on Obesity Parameters and Insulin Resistance

Status Completed

Clinical Trial Summary

Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Smectite is a natural silicate clay belonging to the dioctahedral smectite class formed from aluminomagnesium silicate. It is not absorbed from the gastrointestinal tract, but binds to intestinal mucous, forms multilayer structure with high plastic viscosity and powerful coating properties hence preserving integrity of the mucus, and has the ability to absorb directly bacterial toxins, bacteria, viruses and bile salts. The current study aim was to conduct placebo-controlled randomize clinical trial for the efficiency of a combination of multiprobiotics with smectite (Symbiter-Forte formulation) as an adjunction to the standard anti-diabetic therapy on IR, glycemic control parameters, β-cells functional activity, anthropometric parameters and markers of a chronic systemic inflammatory response in type 2 diabetes patients.

Clinical Trial Description

In this single-center double-blind, placebo controlled, parallel group study, 55 type 2 diabetes patients from the Kyiv City Clinical Endocrinology Center were selected. They were randomly assigned to receive "Symbiter Smectite" or placebo for 8 weeks, administered as a sachet formulation in double-blind treatment. Randomization was done by the study statistician based on a computer-generated list. The groups were homogeneous according to age, sex and diagnostic criteria. The assignment of groups was 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 "Symbiter Smectite" was supplied by Scientific and Production Company "O.D. Prolisok". It contains a biomass of alive probiotic microorganism symbiosis, colony forming units - CFU/g: Lactobacillus - 1.0х109, Bifidobacterium - 1.0х109, Lactococcus - 1.0х108, Propionibacterium

• 1.0х108 and Acetobacter - 1.0х105; and smectite gel (250 mg). Over 8 weeks of interventional period, the patient received 1 sachet (10 grams) of probiotic-smectite and placebo per day. All sachets were identical with similar organoleptic characteristics (e.g., taste and appearance).

The pre-randomization period was 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 were instructed in one-on-one sessions with a dietitian to follow a therapeutic lifestyle-change diet as classified by the NCEP. In addition, participants were instructed to continue with stable anti-hyperglycemic treatment and received standardized mild physical training for 1 hour per day.

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