Abstract
In the large conduit arteries, elastin is important in maintaining vascular compliance. Studies in animal models suggest that elastin degradation may promote arteriosclerotic vascular changes. There is already a well-established link between aortic stiffening and mortality in the general population and in patients undergoing dialysis. Elastin degradation is mediated by several proteases, including matrix metalloproteinase 2 and cathepsin S. Elastin turnover may be inferred by measuring serum levels of elastin-derived peptides. We analyzed the serum concentration of these biomarkers, their endogenous inhibitors, and aortic pulse wave velocity in 200 patients with stages 3 and 4 chronic kidney..
