Lack of association between ADIPOQ rs266729 and ADIPOQ rs1501299 polymorphisms and cardiovascular disease in rheumatoid arthritis patients

Abstract

To assess the potential association between ADIPOQ rs266729 and rs1501299 gene polymorphisms, either isolated or in combination, and cardiovascular disease in patients with rheumatoid arthritis (RA), 674 patients seen at the rheumatology outpatient clinics of Hospital Xeral-Calde, Lugo, and Hospital San Carlos, Madrid, Spain, were analyzed. Genotyping was performed using predesigned TaqMan assays (Applied Biosystems, Foster City, CA). Carotid intima-media thickness, flow-mediated endothelium-dependent and endothelium-independent post-nitroglycerin vasodilatation, which are used as surrogate markers of subclinical atherosclerosis, were measured in a subsample. No significant differences in the genotype, allele or allele combination frequencies of both polymorphisms were found between RA patients with or without cardiovascular events or subclinical atherosclerosis. Therefore, ADIPOQ rs266729 and rs1501299 polymorphisms do not seem to be associated with cardiovascular disease in RA.
