Background: Type 1 diabetes (T1D) mellitus and obesity are recognized risk factors for cardiovascular disease (CVD). A common mechanism underlying an increased risk for endothelial dysfunction in these two metabolic diseases is oxidative stress.
Objective: To evaluate and compare the oxidant/antioxidant defense systems in children affected with T1D or obesity in order to determine the importance of oxidative stress before the emergence of complications.
Diabetic nephropathy (DN), a major cause of morbidity and mortality in diabetes, will develop within a subset of type 1 diabetes mellitus (T1DM) patients, and oxidative stress has been implicated in its pathogenesis. To investigate the relationship between indicators of early DN stages (hyperfiltration estimated by creatinine clearance > or =150 ml/min per 1.73 m(2), microalbuminuria) and oxidative stress, a prospective study was conducted in 29 T1DM patients (age 13.
