Protocol summary

Study aim
Determining the effect of astaxanthin supplement on glycemic indexes and oxidative stress markers in type 2 diabetic patients treated by metformin
Design
The clinical trial has a control group. A double-blind, randomized study. 1- metformin is prescribed with placebo. 2- metformin is prescribed with astaxanthin.
Settings and conduct
The study population was from patients referring to Endocrine and Metabolism Research Center of Isfahan and conducted tests at the Faculty of Pharmacy of Isfahan University of Medical Sciences. The following biochemical parameters are measured in two groups of treatment and control before and 8 weeks after treatment: blood glucose and glycosylated sugar, blood lipids, uric acid, serum creatinine, and blood urea Other tests: Investigation of Gluconeogenesis on RBC by RT-PCR Evaluation of cell signaling protein expression on white blood cells by western blot method The activity of catalase, malondialdehyde, superoxide dismutase enzymes, total antioxidant capacity in serum The activity of the sodium-potassium channel in red blood cells
Participants/Inclusion and exclusion criteria
Inclusion criteria: type 2 diabetic patients treated by metformin nonInclusion criteria: patients with type 1 diabetes, Pregnant women. Women in lactation, Taking any antidiabetic drug other than metformin, Patients with other endocrine disorders, Take any other antioxidant supplement
Intervention groups
One group will be taken metformin (1000-1500 mg/day) plus astaxanthin supplementation 10 mg/day and other groups will be taken metformin 1500-1000 mg/day plus astaxanthin placebo For 8 weeks All steps for the treatment process are under the supervision of a doctor.
Main outcome variables
(Age)Increasing the efficacy of treatment in improving the oxidative index of patients and serum lipid and enzyme indices of serum and signaling routes

Randomization (investigator's opinion)
Randomized
Randomization description
from among patients in the Isfahan Endocrine and Metabolism Center, 50 patients with type 2 diabetes who are merely treated with metformin are selected available and easy to use.Then, the names of the patients were entered into the SPSS software and using the software, they are randomly divided into two groups of 25 intervention and placebo groups.
Blinding (investigator's opinion)
Double blinded
Blinding description
For this purpose, based on the supplement we used in this intervention, which is the softgel, the placebo is designed and the investigator is aware of the difference between the two, but the patients and the statistical counselor do not know this difference.

Primary outcomes

1

Description
Glycemic Indexes: Following the intervention, we expect the glycemic indexes of the patients (treated with astaxanthin and metformin) to differ from the control group (placebo and metformin).
Timepoint
Initially (before the intervention) and at the end (8 weeks after the intervention)
Method of measurement
(Glycemic indexes in this study include fasting blood sugar, glycated hemoglobin, and insulin). Fasting blood Glucose: Colorimetric Method - Glycated Hemoglobin: High Performance Liquid Chromatography - Insulin: ELISA Technique

2

Description
Oxidative stress: Following the intervention, we expect the oxidative stress markers of the patients (treated with astaxanthin and metformin) to differ from the control group (placebo and metformin).
Timepoint
Initially (before the intervention) and at the end (8 weeks after the intervention)
Method of measurement
The oxidative stress in this study is measured by markers that are: total antioxidant capacity, malondialdehyde, catalase and superoxide dismutase, all of which are measured by Spectrophotometry and with relevant reagents.

Description
Intervention group: Intervention group: Diabetic group treated with metformin / astaxanthin.This intervention is intended to evaluate the efficacy of treatment for diabetic patients. Based on the explanation given in the proposed text Astaxanthin (3,3'-dihydroxy-β, β'-carotene-4,4'-dione) is a natural red or orange carotenoid compound that exists in different microorganisms and seafood.The main source of food is Astaxanthin, the hematococcus pluvialis (Haematococcus pluvialis), which is a green microalgae and enters the human body by eating fish and sea animals. It has an antioxidant strength of 550 times the antioxidant value of vitamin E (32).Astaxanthin has been reported to play an important role in lipid and sugar intake, in addition to anti-inflammatory effects, and the protection of the nervous system and the cardiovascular system.Various action mechanisms have been proposed for this antioxidant such as:activation of AMPK 2. regulating the PI3K / Akt signaling path in the liver 3. Increased glucose uptake by tissues (increased insulin sensitivity).It is expected that the use of this carotenoid in combination with metformin, which is almost the same mechanism of action, can be effective in increasing the efficacy of treatment. Also, considering the role of oxidative stress in the development of chronic diabetes complications and the role of diminished glucose lowering drugs in reducing these complications, Using this antioxidant can be taken to reduce the complications of diabetes in these patients.The subjects were divided into two equal groups and each group was divided into 25 patients.1. Metformin / placebo group: This metformin (glucophage) group is given at a dose of 1000-1500 mg / day plus one placebo daily.2. Group treated with metformin / astaxanthin: This group of metformin (glucophage) with a dose of mg / day 1000-1500 with astaxanthin with a dose of 10 mg/day is given as a softgel (WAKA TANI Astaxanthin Supplement)
