Advanced oxidation protein products and their relationship with cardiovascular risk factors in young apparently healthy people.

INTRODUCTION

Advanced oxidation protein products (AOPPs) are used as a marker to estimate oxidative stress in plasma proteins. Oxidative stress is considered a factor of cardiovascular risk (CVRF) related to increased blood pressure, and dyslipidaemia. The aim of this study was to evaluate the association between plasma AOPPs and CVRF in apparently healthy young adults.

METHODS

A prospective cross-sectional study was conducted on 120 students of the Faculty of Chemical-Pharmacobiology of the UMSNH. Body mass index (BMI) and blood pressure were determined. A blood specimen was also collected to quantify AOPPs, glucose, total cholesterol, lipoproteins (high, low, and very low density), and triglycerides.

RESULTS

Differences were observed in the groups with and without CVRF, with significant differences in BMI, waist, body fat (P<.05), and lipid profile (P<.0001). AOPPs were higher in the group of young people with three and four CVRF (F: 4.651; P=.002). A negatively correlation was found between AOPPs and LDL cholesterol (r=-0.364; P=.0001).

CONCLUSIONS

It was observed that AOPPs concentrations are increased as CVRF increase in young adults. Thus, this could be considered an important risk factor, because their deposition in the atherosclerotic plaque favours the atherogenic process, and thus the development of cardiovascular disease. Quantification of AOPPs contributes to the indirect determination of oxidative status in the body. The study of metabolic and oxidative state of apparently healthy young adults is important in the prevention of cardiovascular disease in later life. More longitudinal studies are required to study its evolution.
