Oat β-glucans as a Supplement in Chilean Subjects With Type 2 Diabetes for Metabolic Control

Objective: To evaluate the effect of oat β-glucans on the satiety perception, metabolic control and intestinal microbiota of type 2 diabetics from Talca, Chile. Methodology: Clinical trial, controlled, randomized, double blind and parallel design. The recruited (40 subjects) were randomized into two groups, placebo (PL) and ß-glucan (BG). 5 gr of oat ß-glucan or placebo were delivered for 12 weeks to be added in breakfast. Blood and stool samples were requested at the beginning and at the end of the intervention. The investigators quantify: HbA1c in whole blood, fasting blood glucose, basal insulin, C-peptide, tumor necrosis factor alpha (TNF-a), interleukin (IL) 6, IL-8, IL-10, IL1β, cortisol, ghrelin, glucagon-like peptide type 1 (GLP -1), YY peptide (PYY), Resistin, Leptin and serum Lipid Profile. The subjective perception of hunger / satiety were established through an analogous visual survey. Calorie intake was determined by 24-hour recall survey. Were analyzed the phylum: Firmicutes, Bacteroidetes and Verrucomicrobia, and the populations of Bifidobacteria spp, Lactobacillus spp, butyrate producing bacteria, Akkermansia Muciniphila and total bacteria of fecal microbiota, using quantitative polymerase chain reaction (qPCR) with specific primers. All participants were instructed not to make changes in their usual eating habits, physical activity and pharmacological treatments.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Beta-Glucan (BETA)
experimental group, received a supplement of oats beta-glucan (5 g) for 12 weeks.
Dietary supplement: Oat Beta-glucan as a Supplement in Type 2 Diabetics
44 subjects were randomized into two groups, placebo (PL) and β-glucan (BG). Each person received a package with a supplement sufficient for 12 weeks, adding 5 g of supplement to breakfast, which could contain beta-glucan or not. Blood and stool samples were requested at the beginning and at the end of the intervention.
Placebo Comparator: Control (CN)
placebo group, received a supplement of cellulose microcrystalline (5g) for 12 weeks.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
