Adhesion molecules and atherosclerosis in ankylosing spondylitis: implications for cardiovascular risk.

Ankylosing Spondylitis (AS) stands as a chronic inflammatory arthritis within the spondyloarthritis spectrum, notably increasing cardiovascular (CV) risk and mortality through accelerated atherosclerosis compared to the non-affected population. While evidence in some studies supports a higher cardiovascular morbidity in AS patients, results from other studies reveal no significant disparities in atherosclerotic markers between AS individuals and healthy controls. This discrepancy may arise from the complex interaction between traditional CV risk factors and AS inflammatory burden. Endothelial dysfunction, a recognized antecedent of atherosclerosis prevalent among most individuals with AS, demonstrates the synergistic impact of inflammation and conventional risk factors on endothelial injury, consequently hastening the progression of atherosclerosis. Remarkably, endothelial dysfunction can precede vascular pathology in AS, suggesting a unique relationship between inflammation, atherosclerosis, and vascular damage. The role of adhesion molecules in the development of atherosclerosis, facilitating leukocyte adherence and migration into vascular walls, underscores the predictive value of soluble intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) levels for cardiovascular events. Despite significant progress in comprehending the pathogenesis of AS and its associated cardiovascular implications, the interplay among inflammation, endothelial dysfunction, and atherosclerosis remains partially elucidated. Investigations into the efficacy of therapeutic approaches involving angiotensin receptor blockers and statins have demonstrated reduced cardiovascular risk in AS patients, underscoring the imperative for additional research in this domain.
