Recent trials do not support a role for vitamin D supplementation in prevention or treatment of type 2 diabetes mellitus, although effects may differ in Asian populations. In this pilot secondary analysis of a placebo-controlled randomised trial of overweight or obese individuals with low 25-hydroxyvitamin D (25(OH)D<50 nmol/L), we examined whether vitamin D supplementation improved insulin sensitivity or body composition in participants of Asian ethnicity. Amongst 65 trial participants, 33 reported being of Asian descent (mean ± SD age 30 ± 7 years; 67% male)...

A 73-year-old female patient with a history of type 2 DM for seven years was admitted to our out-patient clinic with a complaint of frequent hypoglycemic episodes. She was receiving basal- bolus insulin treatment. She underwent liver transplantation 20 months ago due to end stage liver disease caused by HCV infection genotype 1b. While she was still on tacrolimus for liver transplantation, she received direct acting antiviral agents including fix dose ledipasvir-sofosbuvir with ribavirin. Biochemical analysis showed fasting plasma glucose of 105 mg/dl and postprandial glucose of 200 mg/dl, glycosylated hemoglobin A1c of 4...

Insulin degludec (IDeg) is a new insulin formulation that facilitates long-term control of glucose level in humans. In this study, we investigated the effects of IDeg on glycemic control in dogs. Its time-action profiles were monitored in healthy dogs using an artificial pancreas apparatus under euglycemic conditions. At 9.0-13.5 hr post-IDeg injection, an indistinct peak of glucose level was detected. Moreover, the action of IDeg was persistent for >20 hr. Both IDeg and neutral protamine Hagedorn insulin (NPH) lowered blood glucose concentrations in diabetic dogs, but IDeg caused postprandial hyperglycemia and a somewhat lower preprandial glucose level than that caused by NPH...

Insulin resistance increases the risk for cardiovascular disease (CVD) even in the absence of classic risk factors, such as hyperglycemia, hypertension, dyslipidemia, and obesity. Low-grade chronic inflammatory state is associated both with insulin resistance and atherosclerosis. An increased circulating level of proinflammatory proatherogenic factors and biomarkers of endothelial activation was observed in diabetes and CVD. The aim of our study was to assess serum proatherogenic and proinflammatory factors in young healthy nonobese subjects with positive family history of type 2 diabetes...

Angiotensin converting enzyme (ACE) inhibitors reduce body weight, lower blood pressure (BP), and improve insulin sensitivity in animal models of cardiometabolic syndrome. These effects are generally attributed to reduced angiotensin (Ang) II formation; however, these therapies also increase levels of Ang-(1-7), a beneficial hormone opposing Ang II actions. We hypothesized this Ang-(1-7) generation contributes to the insulin sensitizing effects of ACE inhibition in obese mice. Adult male C57BL/6J mice were placed on a 60% high fat diet for 11 weeks...

Insulin is critical for glucose homeostasis, and insulin deficiency or resistance leads to the development of diabetes. Recent evidence suggests that diabetes can be remitted independent of insulin. However, the underlying mechanism remains largely elusive. In this study, we utilized metabolic surgery as a tool to identify the non-insulin determinant mechanism. Here, we report that the most common metabolic surgery, Roux-en-Y gastric bypass (RYGB), reduced insulin production but persistently maintained euglycemia in healthy Sprague-Dawley (SD) rats and C57 mice...

Simvastatin is a cholesterol-lowering drug that is prescribed to lower the risk of cardiovascular disease following high levels of blood cholesterol. There is a possible risk of new onset diabetes mellitus with statin treatment but the mechanisms behind are unknown. Coenzyme Q10 (CoQ10) supplementation has been found to improve glucose homeostasis in various patient populations and may increase muscle GLUT4 content. Our aim was to investigate whether eight weeks of CoQ10 supplementation can improve glucose homeostasis in simvastatin treated subjects...

We sought to identify circulating microRNAs as biomarkers of prevalent or incident diabetes. In a pilot study of 18 sex- and age-matched patients with metabolic syndrome, nine of whom developed diabetes during 6 years of follow-up, an array of 372 microRNAs discovered significantly elevated serum levels of microRNAs -122, -192, -194, and -215 in patients who developed diabetes mellitus type 2 (T2DM). In two cross-sectional validation studies, one encompassing sex- and age-matched groups of patients with T2DM, impaired fasting glucose (IFG) and euglycemic controls (n = 43 each) and the other 53 patients with type 1 diabetes and 54 age- and BMI-matched euglycemic controls, serum levels of miR-192, miR-194, and mi215 were significantly higher in diabetic subjects than in probands with euglycemia or IFG...

Sodium Glucose Cotransporters 1 (SGLT1) play important roles in the intestinal absorption of glucose and the renal reabsorption of glucose, especially in patients with uncontrolled diabetes and those receiving SGLT2 inhibitors. As a consequence, the inhibition of SGLT1 transporters may represent an interesting therapeutic option in patients with diabetes. However, genetic models of SGLT1 inactivation indicate that the malfunction of these transporters may have adverse effects on various tissues. In this review, we discuss the available evidence on the beneficial and detrimental effects that the inhibition of SGLT1 transporters might have...

Background: Acute inflammation, and subsequent release of bacterial products (e.g. LPS), inflammatory cytokines, and stress hormones, is catabolic, and the loss of lean body mass predicts morbidity and mortality. Lipid intermediates may reduce protein loss, but the roles of free fatty acids (FFAs) and ketone bodies during acute inflammation are unclear. Objective: We aimed to test whether infusions of 3-hydroxybutyrate (3OHB), FFAs, and saline reduce protein catabolism during exposure to LPS and Acipimox (to restrict and control endogenous lipolysis)...

Sepsis is a common and often fatal consequence of severe burn injury, but its exact effects on whole body and muscle metabolism in the burn patient is unclear. To address this, 13 septic and 11 nonseptic patients (age: 36.9 ± 13.0 years) with burns encompassing >30% of their total body surface area underwent muscle protein kinetic studies under postabsorptive conditions using bolus injections of ring-C6 and N phenylalanine isotopes. In parallel, whole-body lipid and carbohydrate kinetics were assessed using constant infusions of [U-C6]palmitate, [6,6-H2]glucose, and [H5]glycerol, and during a 2-h hyperinsulinemic euglycemic clamp...
