Relationship of the low-density lipoprotein (LDL)/high-density lipoprotein (HDL) index with antioxidant enzymes and with the oxLDL/HDL index.

Introduction: The low-density lipoprotein (LDL)/high-density lipoprotein (HDL) index is a predictive factor for atherosclerosis, which is associated with oxidative modifications.

Objective: To assess the association of the index with oxidative stress markers.

Methods: 444 subjects were included and were clinically, anthropometrically and biochemically characterized; superoxide dismutase, glutathione peroxidase 3 (GPx3), magnesium and oxidized LDL (oxLDL) index (oxLDL/HDL) were quantified.

Association of the Metabolic Syndrome with Antioxidant Defense and Outstanding Superoxide Dismutase Activity in Mexican Subjects.

Background: Metabolic syndrome (MetS) is considered a public health problem worldwide. Recently, oxidative stress (OS) has been proposed as a factor related with the genesis of MetS. Different studies have reported decreased antioxidant defense, such as superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GRed) activities, and reduced glutathione (GSH) concentration, and, on the other hand, an increase in nitrotyrosine concentration in MetS patients.
