INTRODUCTION: HbA1c is the gold standard for glycemic control in pre-diabetes and diabetes. However, its validity has been questioned, especially in the presence of imbalanced iron homeostasis. The CLEVER trial aims to evaluate the relationship between iron deficiency and HbA1c (a biomarker for the diagnosis and therapeutic monitoring of type 2 diabetes) in a randomized, placebo-controlled, multicenter clinical trial. METHODS: The CLEVER (intravenous ferric CarboxymaLtosE for improVement of mEtabolic parameters in type 2 diabetes patients with iRon deficiency) trial is a randomized, single-blind, proof-of-concept study with two treatment arms...

Congenital hyperinsulinism is a rare disorder that commonly presents in the immediate postnatal period as persistent hypoglycemia. The condition is frequently resistant to medical therapies, and the genetic mutations implicated in the disorder can be predictive of response to therapy. Evaluation of hypoglycemia in the illustrative case presented in this article led to genetic testing identifying recessive mutations in the potassium channel subunits of the beta-islet pancreatic cells. Potassium channel defects are often refractory to medical therapies, so near-total pancreatectomy is usually indicated; however, genetic mutations leading to metabolic dysregulation within the beta-islet pancreatic cells are usually responsive to medical therapy...

PURPOSE OF REVIEW: Polycystic ovary syndrome (PCOS) is diagnosed by its characteristic reproductive features. However, PCOS is also associated with metabolic abnormalities, including insulin resistance and β-cell dysfunction. The severity of these abnormalities varies according to the reproductive phenotype, with the so-called NIH or classic phenotype conferring the greatest metabolic risk. The increased risk for type 2 diabetes (T2D) is well established among affected women with the NIH phenotype, but whether PCOS also confers an increased risk for cardiovascular events remains unknown...

The role of exogenous testosterone (methyltrienolone) in the repair of damaged pancreatic islet and liver cells during alloxan diabetes was studied. Modeling of diabetes was performed through single intraperitoneal injection of Alloxan, with the dose 2 mg per 10 g of body weight. Pancreatic and liver tissues were investigated microscopically using 3-4 µm slices embedded in paraffin and stained with hematoxylin and eosin. Software Adobe Photoshop was used to measure the areas of pancreatic islets as well as areas of necrotic foci in these islets of animals with Alloxan-induced experimental diabetes...

BACKGROUND: Insulin receptors are widely expressed in the brain and may represent a crossroad between metabolic and cognitive disorders. Although antipsychotics, such as olanzapine, are the cornerstone treatment for schizophrenia, they are associated with high rates of type 2 diabetes and lack efficacy for illness-related cognitive deficits. Historically, this risk of diabetes was attributed to the weight gain propensity of antipsychotics, but recent work suggests antipsychotics can have weight-independent diabetogenic effects involving unknown brain-mediated mechanisms...

Transplantation of pancreatic islets for treating type 1 diabetes is restricted to patients with critical metabolic lability resulting from the need for immunosuppression and the shortage of donor organs. To overcome these barriers, we developed a strategy to macroencapsulate islets from different sources that allow their survival and function without immunosuppression. Here we report successful and safe transplantation of porcine islets with a bioartificial pancreas device in diabetic primates without any immune suppression...

Metabolic syndrome typically includes Type 2 diabetes associated with hyperglycemia, central obesity, dyslipidemia and hypertension. It is highly related to oxidative stress, formation of advanced glycated end products (AGEs) and key enzymes, such as carbohydrate digesting enzymes like pancreatic α-amylase and intestinal α-glucosidase, pancreatic lipase and angiotensin I-converting enzyme (ACE). This study used an in vitro approach to assess the potential of four extracts of Siegesbeckia orientalis linne on key enzymes relevant to metabolic syndrome...

Long non-coding RNAs (LncRNAs) are a class of endogenous RNA molecules, which have a transcribing length of over 200 nt, lack a complete functional open reading frame (ORF), and rarely encode a functional short peptide. Recent studies have revealed that disruption of LncRNAs levels correlates with several human diseases, including diabetes mellitus (DM), a complex multifactorial metabolic disorder affecting more than 400 million people worldwide. LncRNAs are emerging as pivotal regulators in various biological processes, in the progression of DM and its associated complications, involving pancreatic β-cell disorder, insulin resistance, and epigenetic regulation, etc...

Insulin resistance is an abnormal physiological state that occurs when insulin from pancreatic β-cells is unable to trigger a signal transduction pathway in target organs such as the liver, muscles and adipose tissues. The loss of insulin sensitivity is generally associated with persistent hyperglycemia (diabetes), hyperinsulinemia, fatty acids and/or lipid dysregulation which are often prevalent under obesity conditions. Hence, insulin sensitizers are one class of drugs currently employed to treat diabetes and associated metabolic disorders...

Eruptive xanthomas are benign skin lesions caused by localised deposition of lipids in the dermis. Xanthomas can present as early manifestations of systemic disorders, which are typically caused by elevated levels of serum triglycerides and uncontrolled diabetes. Early recognition and treatment of the underlying condition decreases morbidity and mortality. After treatment of the underlying metabolic disorders, lesions mostly disappear without leaving scars. We present a case with multiple yellowish, erythematous papules on the extremities suggestive of eruptive xanthomas admitted to our hospital with acute pancreatitis...

Acute pancreatitis (AP) is a common gastrointestinal disorder that featured by acute inflammatory responses leading to systemic inflammatory response syndrome (SIRS) or multiple organ failure. A worldwide increase in annual incidence has been observed during the past decade with high acute hospitalization and mortality. Lack of any specific treatment for AP, even to this day, is a reminder that there is much to be learned about the exact pathogenesis of AP. Fortunately, the discovery of microRNA (miRNA) has started an entirely new thought process regarding the molecular mechanism associated with the disease processes...

PURPOSE OF REVIEW: We provide an overview of current evidence about the independent role of high triglyceride levels for cardiovascular risk and for acute pancreatitis. RECENT FINDINGS: Natural experiments of Mendelian randomization have given us a deeper understanding about the molecular pathways involved in triglyceride metabolism. Individuals with low-triglyceride levels generally have lower rates of cardiovascular disease (CVD). There has been a significant growth in the development of new agents that modulate enzymes involved in a variety of aspects of triglyceride packaging into VLDL or chylomicron particles, and triglyceride catabolism...

Type 1 diabetes (T1D) is the most common chronic metabolic disorder in children. Epigenetic and environmental factors capable of altering the penetrance of major susceptibility genes or capable of increasing the penetrance of low-risk genes are currently thought to play a role in triggering autoimmunity and T1D development. This paper discusses the current knowledge of the role of viruses in T1D. Most studies that have evaluated the potential association between viral infections and T1D have indicated that it is highly likely that some of these infectious agents play a role in T1D development...
