Abstract

Antiphospholipid and anti-oxidized LDL (anti-oxLDL) antibodies are associated with thrombosis and atherosclerosis. Rheumatoid arthritis (RA) is characterized by excess atherosclerosis and cardiovascular diseases. Our aim was to determine whether antiphospholipid and anti-oxLDL antibodies are associated with early atherosclerotic changes in RA. The levels of IgG and IgM anticardiolipin, IgG and IgM anti-beta-2-glycoprotein-I and anti-oxLDL autoantibodies have been evaluated in 82 patients having RA. Carotid artery intima-media thickness (IMT) was measured in the carotid arteries in the common carotid, bifurcation and internal carotid arteries. Elevated levels of IgG anticardiolipin antibodies were detected in 17 of 82 (21%) RA patients, including 7 with medium-to-high levels considered being clinically relevant. These patients had significantly elevated mean carotid and carotid bifurcation IMT compared with RA patients without elevated anticardiolipin. No such association was found regarding other autoantibodies tested. Anticardiolipin antibodies are prevalent in RA and are associated with early atherosclerotic changes, supporting a rational for measuring them in RA, and upon detection treat the patients in order to decrease chances of atherosclerosis progression and thrombosis.
