Effect of Simvastatin and Atorvastatin on Serum Vitamin D and Bone Mineral Density in Hypercholesterolemic Patients: A Cross-Sectional Study

Abstract EN

Background.

Besides lipid-lowering effect of statins, they have been shown to have nonlipid lowering effects, such as improving bone health.

An improvement in bone mineral density (BMD) has been indicated in some studies after the use of statins, in addition to an increase in 25-hydroxyvitamin D (25OHD) level.

The aim of this study is to explore the association between statins and bone health taking into consideration 25OHD level and BMD.

Methods.

This is a randomized, cross-sectional comparative study.

Subjects were divided into two groups, hypercholesterolemic participants taking simvastatin or atorvastatin as the study group and a matched control group not taking statins.

All participants were assessed for serum 25OHD and BMD at lumbar spine and femoral neck.

Results.

A total of 114 participants were included in the study, 57 participants in each group.

Results of serum 25OHD showed no significant difference between study and control groups ( P = 0.47 ), while BMD results of lumbar spine and femoral neck showed significant difference ( P = 0.05 and 0.03, resp.).

Conclusion.

Simvastatin and atorvastatin, at any dose for duration of more than one year, have no additive effect on 25OHD level but have a positive effect on the BMD.
