Vitamin D receptor polymorphisms as tool for early screening of severe bone loss in women patients with rheumatoid arthritis.

Abstract

The results of these studies support an association between specific VDR alleles and bone loss in RA. The TaqI t and BsmI B alleles were associated with an accelerated bone loss in RA, but not with a focal bone loss. These effects of VDR genotypes and vitamin D supplementation are not unexpected, given that the central pathological feature in RA is bone and joint destruction. The VDR SNPs genotyping should be a useful tool to screen early women RA patients with the bone loss.
