Abstract
Background. Vitamin D has been shown to reduce the risk of atherosclerosis development. Vitamin D receptors (VDRs) mediate the protective effects of vitamin D on immune inflammation in the vascular wall. Polymorphisms of the VDR gene are involved in the regulation of the stability of its mRNA. The carriage of some polymorphisms may affect the development of atherosclerosis.Objective. To study the availability of vitamin D in patients with coronary artery disease (CAD) with various VDR polymorphisms.Design and methods. The vitamin D level in blood serum was determined by enzyme immunoassay. The genotypes of the VDR gene were determined in 302 patients with CAD and in 196 patients without CAD by PCR.Results. The level of vitamin D in patients with CAD was lower than in controls. The presence of the studied VDR polymorphisms was not associated with an increased risk of CAD. The content of vitamin D was higher in patients with the BB vs. bb genotype of the VDR gene (BsmI), in carriers of the AA vs. aa genotype (ApaI), in carriers of TT vs. tt genotype of the VDR gene (TaqI).Conclusion. TaqI, FokI, ApaI and BsmI polymorphisms are not associated with the risk of CAD. Vitamin D level in the CAD patients with BB and AA genotype of the VDR gene was higher compare with bb and aa genotypes.
