Hesperidin Supplementation Alleviates Oxidative DNA Damage and Lipid Peroxidation in Type 2 Diabetes: A Randomized Double-Blind Placebo-Controlled Clinical Trial.

This study aimed to examine the effects of hesperidin supplement on the glycemic parameters, oxidative DNA damage, and lipid peroxidation in patients with type 2 diabetes. Sixty-four patients were randomly allocated to receive 500 mg/day hesperidin or placebo capsules for 6 weeks. Data on glycemic parameters, total antioxidant capacity (TAC), 8-hydroxydeoxyguanosine (8-OHDG), and malondialdehyde (MDA) were collected at the baseline and at the end of the study. In hesperidin group, TAC increased (0.74 ± 0.16 vs. 0.82 ± 0.18), while serum froctoseamin (5.79 ± 5.86 vs. 5.01 ± 4.95; p = 0.001), 8-OHDG (14.32 ± 6.4 vs. 11.00 ± 7.0; p = 0.000), and MDA (5.78 ± 1.76 vs. 4.60 ± 0.75; p = 0.000) decreased in comparison with the baseline values. There was a significant difference in percent change of TAC (13.35 ± 19.21 vs. 3.13 ± 10.02; p = 0.043), froctoseamin (-10.10 ± 16.84 vs. 4.27 ± 34.646), 8-OHDG (-25.11 ± 28.23 vs. 8.69 ± 35.41; p = 0.000), and MDA (-16.46 ± 18.04 vs. -1.82 ± 22.63; p = 0.007) between hesperidin and control groups following intervention in adjusted models. These results suggest that hesperidin may improve TAC and alleviate serum froctoseamin, 8-OHDG, and MDA levels in type 2 diabetes. Copyright © 2017 John Wiley & Sons, Ltd.
