Effects of vitamin D on plasma lipid profiles in statin-treated patients with hypercholesterolemia: A randomized placebo-controlled trial

Summary Background & aims Lipid abnormalities are regarded as a risk factor for cardiovascular disease. Low vitamin D status has been shown to be associated with hyperlipidemia. We planned to research the effects of vitamin D supplementation as an adjuvant therapy for patients with hypercholesterolemia. Methods Patients with hypercholesterolemia were enrolled in this single-center, double-blind, placebo-controlled trial in Beijing (39°54′ N). Fifty-six patients were randomly assigned to receive vitamin D ( n  = 28, 2000 IU/d) or a placebo ( n  = 28) as an add-on to statin, by the method of permutated block randomization. Serum lipid levels were evaluated at baseline, 1, 3 and 6 months. Results Vitamin D supplementation resulted in increased serum 25-hydroxyvitamin D concentrations compared with placebo (+16.3 ± 11.4 compared with +2.4 ± 7.1 ng/ml; p p p n  = 43), the serum total cholesterol and triglyceride levels were reduced by −28.5 ± 11.9 mg/dl ( p p Conclusions Vitamin D supplementation might improve serum lipid levels in statin-treated patients with hypercholesterolemia, it might be an adjuvant therapy for patients with hypercholesterolemia.
