The Effect of Insoluble Yeast Beta-glucan Intake on Pre-diabetic Patients
- Conditions
- Pre-diabetic
- Interventions
- Dietary Supplement: Yeast Beta-glucanOther: Placebo
- Registration Number
- NCT03495362
- Lead Sponsor
- Huazhong University of Science and Technology
- Brief Summary
There is a lot of evidence to show that the yeast beta-glucan has immunomodulatory, anti-inflammatory, anti-infective effects.However,few work was done on the relationship between yeast bata-glucan and the immune function of diabetic patients. This is a randomized double-blind trial, aiming to study the effect of yeast beta-glucan on immune system of prediabetic patients. Firstly, the investigators will go into the efficacy of yeast beta-glucan on improving the clinical symptoms of prediabetics. Secondly, the investigators will study the mechanism of yeast beta-glucan on enhancing the immune function and improving the inflammatory response.

- Primary Outcome Measures
Name Time Method Changes in the differentiation rates of some peripheral blood mononuclear cells (PBMCs) At 0 week, 6th week, 12th week in the intervention period. Extract and isolate PBMCs from participants. Using flow cytometry to detect the differentiation rates of some PBMCs（Peripheral Blood Mononuclear Cells）inculding T, B, NK, CD4+, CD8+, CD19+, CD138+, CD3+ and CD45+ cells
Changes in inflammatory factors At 0 week, 6th week, 12th week in the intervention period. Using ELISA to detect the expression level of TNF-α, IL-6, IL-1β, IL-12, IL-10, TGF-β
Changes in blood glucose level At 0 week, 12th week in the intervention period. FPG(fasten plasma glucose), OGTT（oral glucose tolerance test）
Changes in gut microbiota At 0 week, 6th week, 12th week in the intervention period. High-throughput 16S DNA gene amplicon sequencing performed on the Illumina HiSeq platform.
Changes in RTI(respiratory tract infection) Every week across the intervention peroid，an average of 3 months. Observe the clinical symptoms of respiratory infections in two groups of patients
Changes in islet function At 0 week, 12th week in the intervention period. C-peptide level
- Secondary Outcome Measures
Name Time Method Changes in SCFA (short chain fatty acids) At 0 week, 6th week, 12th week in the intervention period. Using GC-MS to detect fecal and plasma SCFA
