Paraoxonase 1 activity as a new biochemical marker in the diagnosis of peripheral arterial disease

Abstract

Aim: Peripheral artery disease (PAD) is an atherosclerotic disease. It is seen in older ages. It causes cardiovascular morbidity and mortality. PAD may progress without any symptoms. Despite its high frequency, there is no laboratory parameter that directly indicates peripheral arterial disease in routine biochemical tests. The relationship between oxidative stress increase and PAD is known. In this study, it is aimed to show the possible usage of the activities of the antioxidant enzymes paraoxonase 1 and arylesterase as a new marker in the diagnosis of PAD. Material and Methods: A total of 70 individuals, including 35 in the control group and 35 peripheral artery patients, were included in this study. The collected blood serums were separated and stored at -80 °C. Paraoxonase 1 and arylesterase activities were measured using the spectrophotometric method in the serum which was dissolved at room temperature. The results were subjected to statistical analysis. P <0.05 was accepted as the level of significance. Results: In the peripheral arterial disease group, the paraoxonase 1 and arylesterase activities were found to be significantly lower than those in the control group (p <0.05). In peripheral arterial disease, paraoxonase 1 and arylesterase activities were shown to decrease. Conclusion: In peripheral arterial disease, paraoxonase 1 and arylesterase activities were found to decrease significantly. The results of similar studies related to atherosclerosis in the literature were in line with our findings. It would be beneficial to support the results of this study with new studies and evaluate paraoxonase 1 and arylesterase activities in routine biochemistry laboratories for the diagnosis and follow-up of peripheral arterial disease.
