The main tissues affected by diabetes complications at the microvasculature levels are reti na order 40mg sotalol, renal glomerulus cheap 40mg sotalol, and peripheral nerves. Diabetes is also associated with accelerated atherosclerotic disease affecting arteries that supply the heart, brain, and lower extremities. Oxidative stress in diabetic complications Oxidative stress plays a pivotal role in the development of diabetes complications, both at the microvascular and macrovascular levels. Results derived from two decades of diabetes complications investigation point towards mitochondrial superoxide overproduction as the main cause of metabolic abnormalities of diabetes. Thus, all of the above reviewed pathways are involved in microvasculature and macrovasculature hyperglycemic damage [24]. Microvascular complications Diabetic retinopathy: Diabetic retinopathy appears in most patients after 10 to 15 years after diabetes onset. Background retinopathy presents small hemorrhages in the middle layers of the retina, appearing as dots. Lipid deposition occurs at the margins of the hemorraghe, and microaneurisms (small vascular dilatations) and edema may appear. Proliferative retin opathy occurs when new blood vessels on the surface of the retina cause vitreous hemor rhage, and eventually, blindness. Sorbitol produced in this proc ess increases osmotic stress, which has been linked to microaneurysm formation, thickening of the basement membranes and loss of pericytes. As mentioned, diabetic patients, and particularly those with nephropaty, have lowered anti oxidant defenses. Diabetic neuropathy: Diabetic neuropathy is defined as the presence of symptoms and/or signs of peripheral nerve dysfunction in diabetic patients after exclusion of other causes. Pe ripheral neuropathy in diabetes may manifest in several different forms, including sensory, focal/multifocal, and autonomic neuropathies. Macrovascular complications The central pathological mechanism in macrovascular complications is atherosclerotic dis ease. Atherosclerosis occurs as a result of chronic inflammation and injury to the arterial wall in the peripheral or coronary vascular system. Additionally, platelet adhesion and hypercoagulability also occurs in type 2 diabetes, increasing the risk of vascular occlusion [70]. It has been proposed that increased superoxide production is the central and major mediator of endothelial tissue damage, causing direct inactivation of two antiatherosclerotic enzymes, endothelial nitric oxide synthase and prostacyclin synthase and that the activation of oxidative stress path ways is involved in the pathogenesis of complications [24]. Endothelial cells also contain high amounts of aldo-keto reductase, and are thus prone to in creased polyol pathway activation. This effect appears to be mediated by O-glucosamine-acylation of the transcription factor, Sp1 [77]. In addition, vitamin C can reduce the oxidized forms of vitamin E and glutha tione [81]. Vitamin E is a fat-soluble vitamin which may interact with lipid hydroperox ides and scavenge them. It also participates, together with vitamin C, in gluthatione regeneration by interaction with lipoic acid [23]. Besides modulating gene expression, cell growth and differentiation, this vitamin may also act as antioxidant, although the mechanisms of action in this role are not fully deci phered. The antioxidant potential of carotenoids (vitamin A) depends on their distinct mem brane-lipid interactions, while some carotenoids can decrease lipid peroxidation, others can stimulate it [82]. Such contrasting results have also been reported for studies looking association of vitamin A and C consumption and amelioration of diabetes status and/or complications [7, 8, 81, 86]. There appears to be no beneficial effect of vitamin supplementation on diabetes or macrovascular complications [7, 8, 81]. Some of these studies have even evidenced associa tions between vitamin supplementation and an increased incidence of stroke [7]. Paradoxically, in spite of the solid evidence of increased oxidative stress in diabetes, and the well established actions of vitamins as antioxidants, the association studies between antioxi dant vitamin status and its beneficial effects in diabetes has no consistent results at all. What is more, interventional studies have failed in demonstrating a favorable effect of vitamin supplementation, discouraging its use as antioxidant therapy for diabetes. First, as vitamins may be easily oxidized, a vitamin may have antioxidant or oxidant properties, depending on the presence of other vitamins and the oxidative state in the cells i. Vitamin doses may also be part of the problem, as the effect of vitamins depends on dietary concentrations and/or supplement intake. The wide variety of doses reached with diet and supplements, and the lack of an established pharmacological dose of vitamins, makes it difficult to ascertain the true net effect of vitamin status or supplementation needed to gen erate beneficial effects. Certainly, glucose levels have been correlated to the presence and severity of the complications. However once hyperglycemia has establish ed, the incidence of complications after tight glycemic control remains the same. Conclusions Diabetes mellitus has reached epidemic proportions in the last decade, becoming one of the most important diseases worldwide. Several studies indicate oxidative stress is present in the dysfunction of insulin action and secretion that occur during diabetes, as well as in the development of diabetic complications.
