Resumen
Background. Prediabetes is an intermediary hyperglycaemic state that precedes type 2 diabetes mellitus (T2DM) in which abnormal metabolism of glucose and lipids occurs in organs such as the liver. Evidence has shown that, about 70% of T2DM patients develop hepatic dysfunction which is found to begin during the prediabetic stage. Bredemolic acid, a pentacyclic triterpene, has been found to improve insulin sensitivity in diet-induced prediabetic rats. The effects of this compound on liver function, however, are unknown. This study was therefore designed to investigate the effects of BA on liver

Resumen
Type 2 diabetes mellitus represents a major global health burden and is often preceded by a prediabetic state characterized by insulin resistance and metabolic dysfunction. Mitochondrial alterations, oxidative stress, and disturbances in lipid metabolism are central to the prediabetes pathophysiology. Melatonin, a pleiotropic indolamine, is known to regulate metabolic and mitochondrial processes; however, its therapeutic potential in prediabetes remains poorly understood.

Resumen
In type 2 diabetes mellitus (T2DM), there is an increased prevalence of cardiovascular disease (CVD), even when corrected for atherosclerosis and other CVD risk factors. Diastolic dysfunction is one of the early changes in cardiac function that precedes the onset of cardiac failure, and it occurs already in the prediabetic state. It is clear that these changes are closely linked to alterations in cardiac metabolism; however, the exact etiology is unknown. In this narrative review, we provide an overview of the early cardiac changes in fatty acid and glucose metabolism in prediabetes and its co

Resumen
A prediabetic state is a major risk factor for the development of diabetes, and, because of an identical pathophysiological background of both conditions, their prevalence increases parallelly and equally fast. Long-term hyperglycemia is the main cause inducing chronic complications of diabetes, yet the range of glucose levels at which they start has not been yet unequivocally determined. The current data show that chronic microvascular complications of diabetes can be observed in patients with abnormal glucose metabolism in whom glycaemia is higher than optimal but below diagnostic criteria f

Abstract Objectives Recent studies have suggested that a high plasma concentration of the branched-chain amino acids (BCAAs) can serve as a biomarker for type-2-diabetes (T2D). Whether this is also the case for prediabetes remains unclear. Our goal is to examine whether specific disturbances exist in the kinetics of the BCAAs leucine, isoleucine and valine in middle aged/older adults with prediabetes.

Prediabetes is a clinically silent, insulin-resistant state with increased risk for the development of type 2 diabetes (T2D) and cardiovascular disease (CVD). Since glucose homeostasis and lipid metabolism are highly intersected and interrelated, an in-depth characterization of qualitative and quantitative abnormalities in lipoproteins could unravel the metabolic pathways underlying the progression of prediabetes to T2D and also the proneness of these patients to developing premature atherosclerosis.

Resumen
AIMS/HYPOTHESIS: Exposure of pancreatic beta cells to cytokines released by islet-infiltrating immune cells induces alterations in gene expression, leading to impaired insulin secretion and apoptosis in the initial phases of type 1 diabetes. Long non-coding RNAs (lncRNAs) are a new class of transcripts participating in the development of many diseases. As little is known about their role in insulin-secreting cells, this study aimed to evaluate their contribution to beta cell dysfunction. METHODS: The expression of lncRNAs was determined by microarray in the MIN6 beta cell line exposed to proin

Resumen
Abstract Hypertension is often associated with insulin resistance, dyslipidemia and obesity, which indicate a prediabetic state and increased risk of cardiovascular disease. Pioglitazone treatment of patients with type 2 diabetes reduces insulin resistance and improves lipid profiles. The present double-blind placebo-controlled study is the first study to report effects of pioglitazone in non-diabetic patients with arterial hypertension. Following a one week run-in, 60 patients were randomized to receive either pioglitazone (45 mg/day) or placebo for 16 weeks. Insulin sensitivity (M-value) inc

As a new mouse model of obesity-induced diabetes generated by combining quantitative trait loci from New Zealand Obese (NZO/HlLt) and Nonobese Nondiabetic (NON/LtJ) mice, NONcNZO10/LtJ (RCS10) male mice developed type 2 diabetes characterized by maturity onset obesity, hyperglycemia, and insulin resistance. To metabolically profile the progression to diabetes in preobese and obese states, a 2-h hyperinsulinemic euglycemic clamp was performed and organ-specific changes in insulin action were assessed in awake RCS10 and NON/LtJ (control) males at 8 and 13 wk of age.

Abstract The criteria of the American Diabetes Association and the WHO for the diagnosis of diabetes mellitus are controversially discussed. In a prospective population study, we evaluated the data of 3737 men, aged 36–60 yr, without diabetes mellitus and with fasting serum glucose levels less than 7 mmol/L at entry into the study who had at least 1 repeat examination during a follow-up of 4–10 yr. During a mean follow-up of 6.3 yr, 200 men developed diabetes mellitus. They differed significantly from 3537 men by body mass index, fasting serum levels of glucose, high density lipoprotein choles

The prevalence of obesity has been increasing dramatically in the last decades in the whole world, not only in industrialized countries but also in developing areas. A major complication of obesity is insulin resistance and type 2 diabetes. Diabetes is also rapidly increasing world-wide – reaching a prevalence in adults of approx. 5–6% in Central Europe and in the US, and more than 50% in specific, genetically prone populations.

Background. The prevalence of childhood obesity has increased significantly over the past three decades worldwide, and in this regard, the frequency of diseases associated with obesity, including disorders of carbohydrate metabolism, has increased. The involvement of insulin resistance and insulin deficiency in the development of prediabetes in obesity has been established. However, the significance of each pathological mechanism in the development of prediabetes in childhood and adolescence has not been established.

Prediabetes is defined as a disorder in which the criteria for diabetes mellitus are not met, but normal blood glucose values are exceeded; this intermediate hyperglycemia is associated with a high risk of developing diabetes and cardiovascular disease. The number of patients with diabetes mellitus continues to grow steadily, and therefore the role of timely interventions at the stage of prediabetes is obvious. A modern approach to preventing the progression of prediabetes includes correcting risk factors for cardiovascular diseases, arterial hypertension, dyslipidemia, weight loss and/or prev

Pre-diabetes is a metabolic condition characterized by insulin resistance and primary or secondary beta cell dysfunction which increases the risk of developing type 2 diabetes mellitus. It is used to describe the intermediate state of abnormal glucose metabolism in which blood glucose levels are higher than normal, but not yet in the range necessary for diagnosis of diabetes. The concept of prediabetes arose in 1950’s when high perinatal mortality was reported in pregnancies before diagnosis of diabetes mellitus.

In the world, the number of patients with carbohydrate metabolism disorders is steadily growing. Over the past 10 years, the number of patients with diabetes mellitus in the world has more than doubled. Moreover, there is not only an increase in the number of patients with diabetes mellitus, predominantly type 2 diabetes, but also with prediabetes. The term «prediabetes» means impaired glucose tolerance and impaired fasting glycemia. To date, it is obvious that the development of prediabetes lead not only to the higher risk of diabetes mellitus in the future, but also of cardiovascular disease

A disparate array of plasma/serum markers provides evidence for chronic inflammation in human prediabetes, a condition that is most closely replicated by standard mouse models of obesity and metaflammation. These remain largely nonactionable and contrast with our rich understanding of inflammation in human type 2 diabetes. New data show that inflammatory profiles produced by CD4+ T cells define human prediabetes as a unique inflammatory state. Regulatory T cells (Treg) control mitochondrial function and cytokine production by CD4+ effector T cells (Teff) in prediabetes and type 2 diabetes by s
