Antibodies to Modified Citrullinated Vimentin Are Associated with Subclinical Atherosclerosis in Early Rheumatoid Arthritis
Rheumatoid arthritis (RA) is associated with increased morbidity and mortality due to cardiovascular disease (CVD), especially accelerated atherosclerosis (1-3). There is evidence that this already occurs early in the disease process. Well known common CVD risk factors interact with the systemic auto-inflammatory response during the disease process and speed up the development of atherosclerosis in patients suffering from rheumatoid arthritis.
Antibodies against citrullinated protein and peptide antigens (ACPA) are highly sensitive and specific markers for early rheumatoid arthritis. Antibodies to Modified Citrullinated Vimentin (anti-MCV) predict poor outcome and appear to play a major role in the pathogenesis of rheumatoid arthritis.
A recently published study by Amal El-Barbary and his co-workers may now shed light on the relationship between anti-MCV antibodies and cardiovascular co-morbidities in patients with rheumatoid arthritis (4). They investigated the correlation of anti-MCV antibodies in early RA with disease activity and cardiovascular risk factors compared to antibodies against cyclic citrullinated peptides (anti-CCP3).
