BACKGROUND
Oxidative stress and inflammation are important factors in the pathogenesis of diabetes and contribute to the development of diabetic complications. To understand the mechanisms that cause vascular complications in diabetes, we examined the effects of high glucose and/or free fatty acids on the production of superoxide from neutrophils and their role in endothelial cell damage. METHODS: Human neutrophils were incubated in the media containing 5.5 mM D-glucose, 30 mM D-glucose, 3 nM oleic acid, or 30 microM oleic acid for 1 hour to evaluate superoxide production through NAD(P)H oxidase activation. Human aortic endothelial cells were co-cultured with neutrophils exposed to high glucose and oleic acid. We then measured neutrophil adhesion to endothelial cells, neutrophil activation and superoxide production, neutrophil-mediated endothelial cell cytotoxicity and subunits of neutrophil NAD(P)H oxidase. RESULTS: After 1 hour of incubation with various concentrations of glucose and oleic acid, neutrophil adherence to high glucose and oleic acid-treated endothelial cells was significantly increased compared with adhesion to low glucose and oleic acid-treated endothelial cells. Incubation of neutrophils with glucose and free fatty acids increased superoxide production in a dose-dependent manner. High glucose and oleic acid treatment significantly increased expression of the membrane components of NAD(P)H oxidase of neutrophil (gp91(phox)). Endothelial cells co-cultured with neutrophils exposed to high glucose and oleic acid showed increased cytolysis, which could be prevented by an antioxidant, N-acetylcysteine. CONCLUSION: These results suggest that high glucose and/orfree fatty acidsincrease injury of endothelial cells via stimulating NAD(P)H oxidase-induced superoxide production from neutrophils.

AbstractAbstract PDF
BACKGROUND
Serum cystatin C has been reported as a better marker than serum creatinine for estimation of kidney function and may be associated with cardiovascular disease. The aim of this study was to elucidate the association of serum cystatin C with metabolic syndrome (MS), a constellation of cardiovascular risk factors, and its related components and the usefulness of serum cystatin C for the cardiovascular risk assessment. METHODS: 1,468 healthy subjects (814 men and 655 women), who visited health promotion center of Pusan National University Hospital for routine medical checkup were included. MS was defined by modified, revised National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III criteria. RESULTS: Mean serum cystatin C value was 0.87 +/- 0.17 mg/L. In partial correlation analysis adjusted by age, sex and Glomerular Filtration Rate (GFR), cystatin C was associated with most of metabolic parameters and especially had significant positive correlation with waist circumference (r = 0.215), triglyceride (TG) (r = 0.141), diastolic blood pressure (BP) (r = 0.116), and correlated negatively with high density lipoprotein (HDL) cholesterol (r = -0.152) (all P < 0.001). There were increasing trends of prevalence of MS with the increase of quartiles of cystatin C and as the number of MS components increased, cystatin C values significantly increased. Serum cystatin C was also significantly increased in MS (0.90 +/- 0.19 mg/L vs. 0.86 +/- 0.16 mg/L). In stepwise multiple regression analysis including the components of MS, Waist circumference, diastolic BP, triglyceride, and HDL cholesterol were independent determinants of serum cystatin C, but with creatinine, only waist circumference was independent determinant. CONCLUSIONS: Serum cystatin C was closely associated with MS and its related cardiovascular risk factors and might be useful as a tool of cardiovascular risk assessment.

AbstractAbstract PDF
Oxidative stress has been considered to be a major contributor to the pathogenesis of the diabetic macrovascular and microvascular complications. In the absence of an appropriate antioxidant defense mechanism, increased oxidative stress leads to the activation of stress-sensitive intracellular signaling pathways and the formation of gene products that cause damage and contribute to the late complications ofdiabetes. The source of reactive oxygen species (ROS) in the pancreatic beta cells and insulin sensitive cells has postulated to be the mitochondrial electron transport chain. NAD(P)H oxidase-dependent ROS production is also important as the source both in pancreatic beta cells and other cells. NAD(P)H oxidase mediated ROS can alter parameters of signal transduction, insulin secretion, insulin action, cell proliferation and cell death. Additionally, oxidative stress as the pathogenic mechanism linking insulin resistance with dysfunction of both pancreatic beta cells and endothelial cells, eventually leads to diabetes and its complications. Further investigation of the mechanisms and its therapeutic interventions based on focusing NAD(P)H oxidase associated ROS production in the islet cells and other islet cells are needed
