Investigating Atherosclerosis In Seronegative Spondyloarthropathy
The association between inflammation and atherosclerosis is widely known. An increase in morbidity and mortality due to cardiovascular (CV) disease in inflammatory rheumatic diseases has been proved \[1-4\]. Rheumatoid arthritis (RA) has the greatest CV impact. Scientific societies and expert groups have developed recommendations for preventing cardiovascular risk in these patients \[5, 6\]. It has also been observed an increased CV risk and greater morbidity in other inflammatory rheumatic diseases such as Ankylosing Spondylitis (AS), psoriatic arthritis (PsA), and inflammatory bowel disease(IBD) \[1, 7n, 8\]. Ankylosing spondylitis (AS) is a systemic inflammatory disorder of unknown etiology that mainly involves the axial skeleton causing the spine, sacroiliac joints arthritis, and peripheral joints arthritis. Its peak age of onset is between 20-30 years affecting young males with the involvement of extra-articular structures such as eyes, kidneys, heart, lung, vessels, and nerves \[9,10\]. Aortitis and aortic regurgitation are cardiovascular complications associated with AS. AS is associated with up to 50% mortality rates and cardiovascular diseases are the main causes of these high mortality rates\[10,11\].
• Age at disease onset above 16 yrs old
• Patients diagnosed as according to 1984 modified New York criteria of AS .including radiographic and non-radiographic AS according to ASAS crteriae\[22\].
• Psoriatic arthritis patients fulfilling the diagnostic criteria defined by the Classification Criteria of Psoriatic Arthritis (CASPAR\[23\]study and with a diagnosis confirmed by a rheumatologist
