NADPH oxidases (NOX) are enzyme complexes that have received much attention as key molecules in the development of vascular dysfunction. NOX have the primary function of generating reactive oxygen species (ROS), and are considered the main source of ROS production in endothelial cells. The endothelium is a thin monolayer that lines the inner surface of blood vessels, acting as a secretory organ to maintain homeostasis of blood flow. The enzymatic production of nitric oxide (NO) by endothelial NO synthase (eNOS) is critical in mediating endothelial function, and oxidative stress can cause dysregulation of eNOS and endothelial dysfunction. Insulin is a stimulus for increases in blood flow and endothelium-dependent vasodilation. However, cardiovascular disease and type 2 diabetes are characterized by poor control of the endothelial cell redox environment, with a shift toward overproduction of ROS by NOX. Studies in models of type 2 diabetes demonstrate that aberrant NOX activation contributes to uncoupling of eNOS and endothelial dysfunction. It is well-established that endothelial dysfunction precedes the onset of cardiovascular disease, therefore NOX are important molecular links between type 2 diabetes and vascular complications. The aim of the current review is to describe the normal, healthy physiological mechanisms involved in endothelial function, and highlight the central role of NOX in mediating endothelial dysfunction when glucose homeostasis is impaired.

Introduction and background Haptoglobin (Hp) is considered to be an antioxidant and protective against cardiovascular complications. Polymorphisms in the Hp gene interact with diabetes mellitus to affect the risk of vascular complications. Methods We review the updated literature about the protean role of Hp and Hp genotypes spanning genomics, molecular, translational and clinical studies. We searched Pubmed, SCOPUS and Google Scholar for all articles using the keywords: haptoglobin and/or haptoglobin polymorphism and diabetes. We review the diverse Hp genotypes, phenotypes and the impact on diabetes complications, including lessons from animal models and in vitro models. We describe the clinical studies on the associations of Hp genotypes with vascular complications in type 1 and type 2 diabetes comprehensively. We review the studies looking at vitamin E supplementation in a personalized manner in Hp2-2 diabetes individuals. Results and conclusion Hp genotypes have evolved as a result of deletions in the traditional Hp genes. The Hp genotypes have been associated with microvascular and macrovascular complications in type 1 diabetes mellitus but the association in type 2 diabetes is more consistent with cardiovascular complications. A preferential benefit of vitamin E and other antioxidants in the Hp2-2 genotype for cardiovascular complications in type 2 diabetes has been seen presumably secondary to interaction with high-density lipoprotein function. Hence, the Hp genotype can be used to personalize antioxidant therapeutics in diabetes patients. These results need to be corroborated in large, global, pragmatic, prospective, cardiovascular outcome trials in type 2 diabetes patients.

The article presents data on the prevalence of diabetes and prediabetes; the high compatibility of diabetes mellitus and cardiovascular pathology; high mortality among patients with diabetes mellitus and coronary heart disease, in the presence of both acute and chronic cardiovascular complications; on the important role of glucose- and lipotoxicity in the progression of carbohydrate metabolism from prediabetes to type 2 diabetes mellitus, the role of hyperglycemia in the deve-lopment of insulin resistance, atherosclerosis, hypertension, liver, kidney, endothelial dysfunction, the role of hyper- and hypoglycemia in the development of acute vascular complications – myocardial infarction, stroke, gangrene of the lower extremities; on the protective role of adiponectin – a predictor of type 2 diabetes mellitus, on the importance of glycemic control for the timely detection of early disorders of carbohydrate metabolism – impaired glucose tolerance and impaired fasting glucose; on the role of metformin in the prevention of progression of prediabetes to type 2 diabetes and cardiac pathology; on the gluco- and cardioprotective role of modern sugar-lowering drugs.

The article discusses topical issues reflecting the high prevalence of diabetes mellitus (DM), the continuing trend towards an increase in the number of patients, the high incidence of vascular complications that lead to early disability and high mortality. The review presents current data on the role of oxidative stress in the development and progression of vascular complications in patients with type 2 diabetes, as well as the mechanisms underlying the imbalance between prooxidants and the antioxidant defense system in this disease. The article presents the role of a balanced diet in achieving metabolic goals and increasing antioxidant protection in type 2 diabetes. The review provides data on the role of vitamins in the correction of metabolic disorders in type 2 diabetes. The increased need for antioxidant vitamins in diabetes is due to impaired glucose metabolism in this category of patients. Food products, which contain polyphenolic compounds, have a pronounced antioxidant and antithrombotic activity, which favorably affect metabolic parameters that contribute to weight loss. Thus, one of the ways to optimize the therapeutic nutrition of patients with type 2 diabetes is the inclusion in the standard hypocaloric diet of specialized food products containing antioxidant vitamins and minor biologically active substances with pronounced antioxidant properties.

AbstractThere is a worldwide epidemic increase in the number of type 2 diabetes (T2DM)patients who frequently associate with cardiovascular disease (CVD). There are datasuggesting that glycemic control does not substantially reduce CVD risk buthyperglycemia increases the risk of CVD. This apparent paradox could be explainedby the role of post-prandial hyperglycemia in the pathogenesis of cardiovascularcomplications in T2DM. There is numerous evidences, both experimental andclinical, for this association but controversies on this topic persist. The aim of thispaper was to review the current literature regarding the role of postprandial glucosein the genesis of CVD in T2DM.

For many years, the diagnosis of diabetes has been made through the laboratory- based measurement of fasting or random blood glucose levels or using OGTT. In the case of diabetes, the major outcome of interest is long term micro vascular complications for which a large body of data has been accumulated leading to the endorsement of HbA1C for diagnosis in many countries worldwide, with some variations in cut-offs and testing strategies.Faridpur Med.
