Over the past decade, there has been substantial interest in
oxidative stress and its potential role in the development of
disease-related pathophysiological complications in diabetes
(1)(2), atherosclerosis and associated
cardiovascular disease (3)(4), cancer
(5), aging (6), and other conditions.
"Oxidative stress" refers to an imbalance between antioxidant and
oxidant-generating systems. An increase in oxidative stress can have a
profound effect on lipoprotein modification, transcription, and cell
function and metabolism. Oxidative stress can arise via various
mechanisms associated with excessive oxygen radical production, such as
autooxidation of glucose and glycated proteins, and glycation of
antioxidant enzymes. Even in healthy subjects, hyperglycemia, increased
free fatty acids, and hyperinsulinemia can trigger oxidative stress
(7). In diabetes, increased blood concentrations of markers
of oxidative stress, especially in patients with poor glycemic control
(8)(9), have been implicated in the development
of vascular complications. The finding of increased oxidative stress in
newly diagnosed children and diabetic patients with no complications
(8) suggests that the increased oxidative stress in diabetes
may not be attributable to the complications but could contribute to
the development of complications. Other studies in patients with
increased concentrations of plasma lipoproteins (10) have
implicated increased oxidative stress with associated
