| 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 efects of resistant dextrin as a prebiotic on the cardiometabolic
risk factors and the status of oxidative stress in patients with T2DM.
Methods Sixty-fve 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 profle, 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 signifcant 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 signifcant 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 signifcant 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. |
