Calcifediol improves lipid profile in osteopenicatorvastatin-treated postmenopausal women
Abstract
BACKGROUND: Low vitamin D serum levels have been associated with unfavourable lipid profile and poorer response to atorvastatin. Aims of this study were to test the effects of 25-hydroxyvitamin D3 (calcifediol) compared to parental vitamin D3 (cholecalciferol) supplementation on modifications of plasma 25(OH)D levels and lipid profile.
MATERIALS AND METHODS: Fifty-seven postmenopausal women (aged 59.03 ± 6.73 years) who were at low risk of fracture and with basal plasma 25(OH)D < 30 ng/mL were included if they were on atorvastatin treatment prescribed as appropriate. Recruited women were randomized to receive oral calcifediol or cholecalciferol, both at a dose of 140 μg according to a weekly regimen.
RESULTS: At baseline, 25(OH)D was negatively associated with BMI (r = -0.37; P = 0.004), total cholesterol (r = -0.31; P = 0.01) and LDL-C (r = -0.32; P = 0.02). After 24 weeks, 25(OH)D increased significantly in both groups (P < 0.001), although higher levels were obtained with calcifediol as compared with cholecalciferol (P < 0.001). Only in the calcifediol group, a significant reduction of LDL-C (P = 0.01) and an increase of HDL-C (P = 0.02) were obtained, even after adjustment for age, and baseline BMI, 25(OH)D and lipid levels (P < 0.05). The percentage changes in 25(OH)D levels were associated with the variations of LDL-C (r = -0.44; P = 0.01) and HDL-C levels (r = 0.30; P = 0.10).
CONCLUSION: Calcifediol administration in osteopenic and dyslipidemic postmenopausal women…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
