    Abstract

    PURPOSE: To examine endothelial function in rheumatoid arthritis patients and to assess whether clinical or genetic factors affect the development of endothelial dysfunction. METHODS: Fifty-five patients fulfilling the 1987 American College of Rheumatology classification criteria for rheumatoid arthritis were recruited from Hospital Xeral-Calde, Lugo, Spain. Patients were required to have been treated for at least 5 years, including current treatment with one or more disease-modifying antirheumatic drugs. Patients with diabetes mellitus, renal insufficiency, or cardiovascular disease were excluded. Thirty-one age-, sex-, and ethnically matched controls were also studied. Endothelium-dependent (postischemia) and -independent (postnitroglycerin) vasodilatation were measured by brachial ultrasonography. Patients were genotyped for human leukocyte antigen (HLA)-DRB1. RESULTS: Patients had decreased endothelium-dependent vasodilatation (mean [± SD], 3.8% ± 4.9%) compared with controls (8.0% ± 4.5%; P
