Aims: Diabetic nephropathy is one of the major microvascular complications of type 2 diabetes which insufficient 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 = 25), and placebo group (n = 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 = 0.001). The reductions in the serum levels of TG, LDL and TC were significant (P = 0.04, P = 0.006 and P = 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.

Coenzyme Q10 supplementation ameliorates inflammatory markers in patients with multiple sclerosis: a double blind, placebo, controlled randomized clinical trial.

Nutr Neurosci 2015 May 10;18(4):169-76. Epub 2014 Jan 10.

Objectives: Multiple sclerosis (MS) is an immune-mediated neurodegenerative disease of central nervous system and recent studies show that inflammatory processes are highly associated with neurodegeneration in the brain. The purpose of this study was to investigate the effect of coenzyme Q10 supplementation on inflammatory and anti-inflammatory markers in patients with MS.

Methods: This randomized, double-blind, placebo-controlled clinical study was performed among 48 patients with relapsing-remitting MS. Subjects were randomly assigned to a placebo group (n = 24) or coenzyme Q10 (CoQ10)-supplemented group (500 mg/day, n = 24). The intervention was administered for 12 weeks. Peripheral blood samples were collected at baseline and after 12-week intervention, to measure inflammatory (tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and matrix metalloproteinase (MMP)-9) and anti-inflammatory (IL-4 and TGF-β) markers.

Results: Forty-five patients completed the study. After 12 weeks of intervention, the TNF-α levels (P = 0.003) decreased significantly in the CoQ10 group. Subjects in the CoQ10 group had significantly lower IL-6 levels (P = 0.037), compared to the placebo group. CoQ10 supplementation also resulted in decreased serum levels of MMP-9 as compared to the placebo group (P = 0.011). However, CoQ10 supplementation did not alter the IL-4 and TGF-β levels (P = 0.16 and P = 0.81, respectively).

Discussion: CoQ10 supplementation at a dosage of 500 mg appears to decrease the inflammatory markers (TNF-α, IL-6, and MMP-9) in patients with MS.
