Continuous glucose monitoring enhances the diagnostic value of mixed meal test in reactive hypoglycemia

Olivetti Ilaria , Grassi Giorgio , Lambertenghi Veronica , Tomelini Michela , Gigliardi Valentina Ramella , Gramaglia Elena , Ghigo Ezio , Broglio Fabio

Background: Clinical reactive hypoglycemic events are defined as the coexistence of plasma glucose <60 mg/dl and autonomic and/or neuroglycopenic symptoms occurring in fed conditions. The diagnosis is based on tests aiming to simulate the causative triggers (i.e. mixed meal test). In clinical practice, however, a high percentage of symptomatic patients results negative to such diagnostic approach, leading to the impression of an inadequate sensitivity of this diagnostic to...

Resting energy expenditure in impaired glucose metabolism

Bilir Betul Ekiz , Atile Neslihan Soysal , Bilir Bulent , Guldiken Sibel

Introduction: Indirect calorimetry is the most frequently used method to measure resting energy expenditure (REE), but the great expense of equipment precludes its widespread use. The best known REE calculation formula is the ‘Harris and Benedict Formula’. The aim of this study is to assess the impact of glucose metabolism status on REE.Methods: Data from 110 subjects with impaired glucose tolerance (IGT), 108 subjects with impaired fasting glu...

The fed to fasting transition differentially affects PEPCK protein expression in pericentral and periportal murine hepatocytes

Herrema H , Baller J F W , Kuipers F , Groen A K , Grefhorst A

Hepatic glucose metabolism is zonated. Glycolysis is mainly localized in hepatocytes surrounding the hepatic vein (pericentral zone) whereas gluconeogenesis is mainly carried out by hepatocytes surrounding the portal vein (periportal zone). Expression of the gene encoding the gluconeogenic enzyme phosphoenolpyruvate carboxykinase (PEPCK, PCK1) is reduced upon feeding, an effect mainly controlled by insulin. PEPCK is considered a peri-portal enzyme. However, the differential ef...

Katalinic D , Nikolac N , Zjacic-Rotkvic V , Solter M , Topic E , Vrkljan M , Plestina S

Introduction: The metabolic syndrome is increasingly recognized as a powerful predictor of patient risk for developing cardiovascular and cerebrovascular complications. It is viewed as the phenotypic confluence of atherogenic dyslipidaemia, hypertension, central obesity and insulin resistance (with or without type 2 diabetes) resulting from dysregulated gene expression and lifestyle behaviours.Aim: Because insulin resistance is a core defect in type 2 di...

TCF7L2 gene variants and plasma C-peptide concentrations in diabetes type 2

Ferreira M C , Marques M C A , Fukui R T , Correia M R , Silva M E R , Rocha D M , Santos R F

Aims/hypothesis: Several data have shown the association between diabetes type 2 (DM2) and transcription factor 7-like 2 (TCF7L2) gene polymorphisms, in several and different ethnical populations. Although the pathophysiology is not completely clear, it seems that beta and alpha cell functions are abnormal. Up to these days there is no clinical data showing association between TCF7L2 gene polymorphism allele rs7903146 T and beta cell insulin and C-peptide contents in DM2 patie...

Effects of the ghrelin gene products on glucose metabolism in C2C12 muscle cells

Grande Cristina , Settanni Fabio , Gesmundo Iacopo , Taliano Marina , Ghigo Ezio , Granata Riccarda

Type II diabetes is a clinical disorder of glucose and fat metabolism, caused by an inability of insulin to promote sufficient glucose uptake into adipose tissue and striated muscle and to prevent glucose output from the liver. Skeletal muscle is an important element for the maintenance of glucose homeostasis because it can increase, after stimulation, glucose uptake from the blood. In previous experiments we found that acylated ghrelin (AG), unacylated ghrelin (UAG), obestati...

Effects of Ramadan fasting on resting energy expenditure in T2DM

Khoshniat Mohsen , Sharghi Sassan

Introduction: Ramadan fasting may alter fuel metabolism and energy expenditure by inducing changes in the meal timing, sleep–wake patterns and physical activity. It could affect blood glucose through disrupting energy balance. Evaluation of resting energy expenditure (REE) could help to recommend best nutrition advices to diabetics for maintaining acceptable metabolic control.Methods: Thirteen type 2 diabetics who were fasted in Ramadan were compare...

Chronic supplementation of β-hydroxy-β methylbutyrate (HMβ) impairs glucose homeostasis in rats under normal conditions

Gerlinger-Romero F G-R , Yonamine C Y Y Yogi , Campello R S C Saldanha , Guimaraes-Ferreira L G-F , Machado U F M Fabres , Nunes M T N Tereza

Aim: HMβ is a metabolite of leucine commonly used by athletes and in medical practice in order to increase muscle mass and/or minimize protein degradation. We have previously shown that chronic intake of HMβ increases GH synthesis and secretion in rats, which might account to its anabolic effect. However HMβ-treated rats, although normoglycemic, exhibited hyperinsulinemia, suggesting an apparent insulin resistance (IR) state. The present study attempted to inves...

Serum levels of fetuin-A correlate with bone turnover biomarkers in patients with type 2 diabetes mellitus

Rasul Sazan , Todoric Jelena , Ilhan Aysegul , Esterbauer Harald , Kautzky-Willer Alexandra

Objective: Fetuin-A, which is a blood protein produced by liver and promotes bone mineralization, is an independent risk factor for type 2 diabetes. Whether Fetuin-A levels relate to the bone metabolism in type 2 diabetic patients is still not clear. Our study aimed to evaluate the relationship of fetuin-A to the markers of bone metabolism and bone turnover in male and female type 2 diabetic patients.Participants and methods: Eighty type 2 diabetic patie...

Linking CERN and TERM: testing the acceleration hypothesis

Dautovic S , Dautovic R

Objective: Catch-up growth might be associated with metabolic risk later in life. The β-cell has a higher energy requirement and poor antioxidant defense. The accelerator hypothesis predicts earlier onset in heavier people, without necessarily a change in risk, and views diabetes as the one disorder of insulin resistance, set against different genetic backgrounds. Insulin resistance is a function of fat mass, and increasing body weight is accompanied by earlier presentati...

Metabolic syndrome in normotensive non diabetic population in Jeddah: a pilot study

Bahijri S , Akbar D , Al Raddadi R

Background and objectives: Identification of metabolic syndrome (MS) is important for the strategy to reduce the prevalence of NIDDM. The latest IDF consensus definition emphasizes waist circumference as the central criteria, while the earlier ATP III definition gives equal importance to different risk factors. In absence of local data on definition of central obesity, it might be inappropriate to use the IDF definition. Therefore, it is aimed to investigate the prevalence of ...

Comparison of the diagnostic criteria for PreDiabetes on a overweight population

Marcelino Mafalda , Chambel Paula , Paradinha Manuel , Domingues Andreia , Passos Dolores , Lopes Luis , Lopes Maria , Castro Joao

Introduction: ‘PreDiabetes’ was considered as a categories of increased risk for diabetes on the last ADA recommendations in 2010. The proposed diagnostic criteria include an HbA1c value between 5.7 and 6.4%, impaired fasting glucose (IFG) (100–125 mg/dl) and impaired glucose tolerance (IGT) levels (2-h values in the oral glucose tolerance test (OGTT) of 140 to 199 mg/dl). The HbA1c as new diagnostic criteria may actually increase the number of patients diagnose...
