Abstract

Purpose: The oxidative stress plays a key role in the initiation, propagation, and development of the complications of type 2 diabetes mellitus (T2DM). This trial aimed to evaluate the effects of resistant dextrin as a prebiotic on the cardiometabolic risk factors and the status of oxidative stress in patients with T2DM. Methods: Sixty-five female subjects with T2DM were assigned to either the intervention (n = 33) or control (n = 32) groups receiving 10 g/day of resistant dextrin or placebo, respectively, for 8 weeks. Fasting blood samples were collected at baseline and post-intervention to determine the serum levels of glycemic indices, lipid profile, atherogenic indices, and soluble receptor for AGEs (sRAGE), carboxymethyl lysine (CML), pentosidine, malondialdehyde (MDA), 8-iso-prostaglandin F2α (8-iso-PGF2α), total antioxidant capacity (TAC), antioxidant enzymes activity, and uric acid. Data were analyzed using SPSS software 17. Paired, unpaired Student’s t tests, and analysis of covariance were used to compare the quantitative variables. Results: Resistant dextrin caused a significant decrease in FPG (− 17.43 mg/dl, 9.80%), TG (− 40.25 mg/dl, 23.01%), TC/HDL (− 0.80, 21.87%), LDL-c/HDL-c (− 0.80, 17.85%), Atherogenic index (− 0.40, 15.80%), LPS (− 6.5 EU/ml, 23.40%) and hs-CRP (− 8.02 ng/ml, 54.00%), MDA (− 1.21 nmol/mL, 25.58%), CML (− 93.40 ng/ml, 26.30%), 8-iso-PGF2α (− 4.65 pg/ml, 15.00%), and a significant increase in TAC (0.33 mmol/L, 36.25%) and s-RAGE (2.10 ng/ml, 28.90%) in the intervention group compared with the control group. No significant changes were observed in glycosylated hemoglobin, total cholesterol, LDL-c, HDL-c, superoxide dismutase, glutathione peroxidase and catalase, pentosidine, and uric acid in the intervention group compared with the control group. Conclusions: Supplementation with resistant dextrin may improve the advanced glycation end-products, sRAGE, and cardiometabolic risk factors in women with type 2 diabetes mellitus. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
