T04-P-022 Advanced glycation and oxidation products in patients with atherosclerosis

BACKGROUND Oxidative stress can potentiate atherogenesis via modification of biological structures and formation of new compounds, e.g. advanced glycation end products (AGEs) and advanced oxidation protein products (AOPP). The aim of the study was to determine AGEs and AOPP in patients with atherosclerosis, effect of statin therapy and relationship to parameters of lipid metabolism. METHODS AND RESULTS AGEs (carboxymethyllysine - ELISA and fluorescent AGEs - spectrofluorimetry) and AOPP (spectrophotometry) were assessed in 42 patients with atherosclerosis and 21 healthy controls. AGEs are significantly elevated in patients with atherosclerosis in comparison with healthy subjects (carboxymethyllysine 9.02+/-1.66 microg/g prot. vs 7.52+/-1.18 microg/g prot., p
