Protocol summary
-
Study aim
-
Study of the effect of synbiotic supplementation on gut microbial, TNF-a and expression of mirRNA-126 and mirRNA-146a in patients with type 2 diabetes
-
Design
-
A clinical trial with a control group, with parallel, double-blind, and randomized groups, will be performed on patients with type 2 diabetes. 72 patients will be randomly assigned to receive the synbiotic and the placebo by using a random number table.
-
Settings and conduct
-
The study is designed as a double blind randomized controlled trial. After receiving informed consent, the demographic information questionnaire will be completed. At the beginning and end of the study,Biochemical and anthropometric measurements and body composition are performed, diet and physical activity will be evaluated by the three-day record form, Expression of microRNA-126 and microRNA-146a will be measured by RealTime PCR, and serum levels of TNF-a will be measured by ELISA and determination of gut microbiom in participants stool samples will be performed with the use of QPCR.
-
Participants/Inclusion and exclusion criteria
-
Inclusion criteria: Men and women with type 2 diabetes, In the age range of 25-65 years, Glycosylated hemoglobin above 6.5% and below 8.5%, BMI 25-35. Exclusion criteria: People with low-immune, pregnant and lactating women, people with special diseases and allergies, inflammatory diseases, and those who use hormone replacement therapy, probiotic consumption or antibiotic treatment within the past month.
-
Intervention groups
-
The intervention group will receive synbiotic capsules (containing probiotic, fructo-oligosaccharide as prebiotic, lactose, magnesium stearate, talc) containing 500 mg and the control group will receive placebo (lactose, magnesium stearate, talc) containing 500 mg for 12 weeks twice a day.
-
Main outcome variables
-
Expression of microRNA-126 and microRNA-146a, serum levels of TNF-a, gut microbiom(6 microorganism)

Randomization description
-
To assign individuals to the intervention and control groups, a random number table will be used. Stratified blocked randomization method will be used based on sex (male and female) and age (25-45 years and 45-65 years), so that the number of samples assigned to each of the groups will be equal.
-
Blinding (investigator's opinion)
-
Double blinded
-
Blinding description
-
Capsules containing synthetic and placebo are similar in shape and appearance and the bottles of Capsules are the same (in terms of color and shape). A and B labels will be fixed on the bottles of Capsules by someone irrelevant to the entire study. participants and researchers will be blinded to the contents in the bottles through out the study.
