Abstract
Obesity is a chronic, multifactorial, and complex disease resulting from a long-term positive energy balance, in which both genetic and environmental factors are involved. A systemic increase in oxidative stress is often observed in obese subjects and is regarded to be directly involved in increasing incidence of obesity - related metabolic complications including cardiovascular diseases. The alteration of lipoprotein levels and compositions are probably related to the greater risk of cardiovascular disease associated with obesity. The present study was designed to assess serum oxLDL levels in a group of patients with obesity and cardiovascular disease (58.3 ? 4.31 years), and a group of healthy patients (55.94 ? 5.67 years). The LDL susceptibility to in vitro induced lipid peroxidation was evaluated following its incubation with a prooxidant system. Results obtained showed the susceptibility of LDL to in vitro oxidation was increase in obesity group (18.42 %) compared with a healthy group. This study indicates that circulating ox-LDL is associated with obesity. This association may be explained by the occurrence of small dense LDL that is more prone to oxidation. Another possible explanation is that adipose tissue contributes to the oxidation of LDL by increase the production of arachi-donate-5-lipoxygenase which catalyze LDL oxidation. In conclusion, it is now clear that obesity is associated with endothelial cell dysfunction, an association that, at least in part, accounts for the increased risk of developing cardiovascular atherosclerosis.
