The Effects of Nano-curcumin on Metabolic Status in Patients With Diabetes on Hemodialysis, a Randomized, Double Blind, Placebo-controlled Trial

Abstract

Introduction. This study evaluated the effects of nano-curcumin intake on metabolic status in patients with diabetes on hemodialysis (HD). Methods. This randomized, double-blind, placebo-controlled clinical trial was performed on 60 patients with diabetes on HD. Participants were randomly divided into two groups to take either 80 mg/d nano-curcumin (n = 30) or placebo (n = 30) for 12 weeks. Results. Nano-curcumin significantly decreased fasting plasma glucose (β = -19.68 mg/dL, 95% CI: -33.48 to -5.88; P < .05) and serum insulin levels (β = -1.70 μIU/mL, 95% CI: -2.96 to -0.44; P < .05) when compared with patients who received placebo. Nanocurcumin treatment was associated with a significant reduction in triglycerides (β = -16.13 mg/dL, 95% CI: -31.51 to -0.75; P < .05), VLDL-cholesterol (β = -3.22 mg/dL, 95% CI: -6.30 to -0.15; P < .05), total cholesterol (β = -17.83 mg/dL, 95% CI: -29.22 to -6.45; P < .05), LDL-cholesterol (β = -15.20 mg/dL, 95% CI: -25.53 to -4.87; P < .05), and total-cholesterol/HDL-cholesterol ratio (β = -1.15, 95% CI: -0.2.10 to -0.21; P < .05) when compared with the placebo. Nanocurcumin also resulted in a significant reduction of serum high sensitivity CRP (β = -0.78 mg/L, 95% CI: -1.41 to -0.15; P < .05), and plasma malondialdehyde (β = -0.25 μmol/L, 95% CI: -0.45 to -0.04; P < .05); but also with a significant increase in plasma total antioxidant capacity (β = 52.43 mmol/L; 95% CI: 4.52 to 100.35; P < .05) and total nitrite levels (β = 3.62 μmol/L, 95% CI: 2.17 to 5.08; P < .001) when compared with placebo. Conclusion. Nano-curcumin intake for 12 weeks had beneficial effects on metabolic profile in patients with diabetes on HD.
