| nsufficient vitamin D might -have a role in it's incidence. This study evaluated the effects of vitamin D
supplementation on lipid profiles and oxidative/anti-oxidative indices in marginal vitamin D status
patients with diabetic nephropathy.
Methods: For the current paralleled, randomized, double-blinded, placebo-controlled clinical trial, 50
diabetic nephropathy patients with marginal serum vitamin D were selected. Intervention group
received 1,25-dihydroxycholecalciferol (50000 IU/week, n ¼ 25), and placebo group (n ¼ 25) received an
identical placebo, for 8 weeks. Lipid profiles (LDL, HDL, TG and TC) and oxidative/anti-oxidative markers
(TAC, SOD, CAT, GPX and MDA) were measured.
Results: Vitamin D supplementation significantly increased vitamin D status in the intervention group,
compared to the control group (P ¼ 0.001). The reductions in the serum levels of TG, LDL and TC were
significant (P ¼ 0.04, P ¼ 0.006 and P ¼ 0.02, respectively) in the intervention group. The changes in
oxidative/anti-oxidative markers and HDL levels were not significant after intervention.
Conclusion: In conclusion, vitamin D supplementation for 8 weeks among diabetic nephropathy patients
has beneficial effects on serum vitamin D status and dyslipidemia. |
