Objective - Homocysteine increases the damage to the cardiovascular system in different ways, one of them is the formation of reactive oxygen species resulting from the auto-oxidation of homocysteine. At the same time, uric acid is one of the major antioxidants in the plasma and protects the cells towards increased ROS activity. In humans, allantoin is only formed from non-enzymatic oxidation of uric acid by free radicals. We aimed to determine the levels of homocysteine, uric acid and allontoin in patients with coronary artery diseases, and to evaluate the possible correlation between homocysteine and allantoin.
