Methods A total of 645 patients fulfilling the American Rheumatism Association 1987 revised classification criteria for RA were studied. Patients were genotyped for the CCR5 rs333 polymorphism using predesigned TaqMan assays. Also HLA DRB1 genotyping was performed using molecular-based methods. Carotid intima-media thickness flow-mediated endothelium-dependent dilatation FMD and endothelium-independent vasodilatation which were used as surrogate markers of subclinical atherosclerosis were measured in a subgroup of patients with no clinical CV disease. Results A lower frequency of carriers of the CCR5A32 allele among patients with CV events versus P odds ratio 95 confidence interval 95 CI to was observed. However after adjusting for gender age at time of RA diagnosis and the presence of shared epitope rheumatoid factor and classic CV risk factors in the Cox regression analysis this reduction of CV events in CCR5AỈ2 allele carriers was slightly outside the range of significance P hazard ratio 95 CI to . Carriers of the CCR5A32 deletion also showed higher FMD values than the remaining patients CCR5 CCR5A32 patients .
