Musculoskeletal abnormalities are common and multiple in diabetic patients. They often result from pathologic changes in the microvasculature (microangiopathy), connective tissue, and peripheral nerves related to chronic hyperglycaemia. Their prevalence in patients with diabetes vary depending upon the diagnostic criteria, the study population and is generally correlated with poor glycaemic control and the occurrence of other complications of diabetes. These entities are important to recognize because they often respond to treatment, preventing pain and disability and improving quality of life...

PURPOSE: Neuropathic pain is a common diabetic complication. It is characterized by symptoms of spontaneous and stimulus-evoked pain including hyperalgesia and allodynia. L-Arginine is a common precursor of many metabolites of biological interest, in particular, nitric oxide (NO), ornithine, and hence polyamines. In central nervous system, NO, glutamate, and polyamines share an N-methyl-D-aspartate (NMDA) receptor-mediated effect. We hypothesized that a variation in arginine metabolism caused by diabetes may contribute to development and maintenance of neuropathic pain and to the worsening of clinical and biological signs of diabetes...

CONTEXT: Balanites aegyptiaca Del. (Zygophyllaceae) fruits are traditionally known for the treatment of hyperglycaemia. Several in vitro and in vivo studies proposed some mechanisms of action. However, clinical trials in human beings were never reported to date. OBJECTIVES: To investigate the antidiabetic efficacy of the 70% ethanol extract of the pericarps of B. aegyptiaca (BE) within a nutritional intervention in elderly people. MATERIALS AND METHODS: Ultra-performance electrospray ionization-mass spectroscopy (UPLC-ESI-MS/MS) analysis was used for metabolic profiling of BE which was incorporated in hard gelatine capsules (400 mg/day) and tested on 30 type 2 diabetes (T2D) Egyptian patients for 8 weeks...

The prevalence of both type 2 diabetes and prediabetes increases with advancing age. The most important factors leading to hyperglycaemia are as follows: deficiency of insulin secretion developing with age, and growing insulin resistance caused by a change in body composition and sarcopaenia. Clinical features of diabetes in the elderly could be different. Diabetes in elderly people is often diagnosed with delay due to atypical symptoms (dementia, urinary incontinence) and occurrence of mainly postprandial hyperglycaemia...

Vascular complications contribute significantly to morbidity and mortality of diabetes mellitus. The primary cause of vascular complications in diabetes mellitus is hyperglycaemia, associated with endothelial dysfunction and impaired neovascularization. Circulating endothelial progenitor cells was shown to play important roles in vascular repair and promoting neovascularization. In this review, we will demonstrate the individual effect of high glucose on endothelial progenitor cells. Endothelial progenitor cells isolated from healthy subjects exposed to high glucose conditions or endothelial progenitor cells isolated from diabetic patients exhibit reduced number of endothelial cell colony forming units, impaired abilities of differentiation, proliferation, adhesion and migration, tubulization, secretion, mobilization and homing, whereas enhanced senescence...

AIMS/HYPOTHESIS: Chronic hyperglycaemia, as measured by HbA1c levels, is a major risk factor for atherosclerosis and cardiovascular disease (CVD) in type 1 diabetes. Our aim was to describe the degree to which the effect of HbA1c on the risk of CVD is mediated by its effect on traditional risk factors over time, and how these mediation pathways change over time. METHODS: The DCCT and its observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC), followed 1441 participants for a mean of 27 years, with periodic measurement of HbA1c and risk factors over time...

Microcephaly with simplified gyration, epilepsy and permanent neonatal diabetes syndrome (MEDS) is a recently described, autosomal recessive-inherited syndrome. We report the case of an infant presenting with lethargy at age five weeks and clinical findings of persistent hyperglycaemia and microcephaly with simplified gyration, suggestive of MEDS. The diagnosis was confirmed by the detection of a known c.233 T > C mutation in the IER3IP1 gene. Only eight cases of MEDS have been reported in the literature...

BACKGROUND: The benefit of initiation of insulin pump therapy (continuous subcutaneous insulin infusion; CSII) in patients with type 1 diabetes using continuous glucose monitoring (CGM) has not been studied. We aimed to assess glycaemic outcomes when switching from multiple daily injections (MDI) to CSII in adults with type 1 diabetes using CGM. METHODS: In this multicentre, randomised controlled trial, 75 adults with type 1 diabetes in the CGM group of the DIAMOND trial were randomly assigned via the study website using a computer-generated sequence to continue MDI or switch to CSII, with continuation of CGM, for 28 weeks...

We report two patients with chronic hyperglycaemia secondary to type 2 diabetes who developed severe vomiting on d. The first patient was diagnosed with a mixed picture of diabetic ketoacidosis (DKA) and hyperosmolar hyperglycaemic state (HHS) and the second, with DKA. They were on insulin therapy which was discontinued on commencing d because of inefficacy and weight gain. The HHS patient developed dehydration secondary to vomiting and had lactic acidosis but no other precipitant could be found in either case...

AIMS/HYPOTHESIS: Previously, we demonstrated that myristic acid (14:0) increases levels of diacylglycerol kinase (DGK) δ, a key enzyme involved in type 2 diabetes exacerbation, and enhances glucose uptake in C2C12 myotube cells. Moreover, results from a population-based cohort study suggest that consumption of high-fat dairy products, which contain high amounts of myristic acid, is associated with a lower risk of developing type 2 diabetes. Taken together, we hypothesised that intake of myristic acid reduces type 2 diabetes risk in vivo...

OBJECTIVE: Patients with type 2 diabetes (T2DM) on insulin therapy are less satisfied with their diabetes treatment than those on oral hypoglycaemic therapies or lifestyle advice only. Determinants of satisfaction in patients with T2DM on insulin therapy are not clearly known. The aim of this study was to determine the association of treatment satisfaction with demographic and clinical characteristics of patients with T2DM. DESIGN: For this study we used data from the GUIDANCE (Guideline Adherence to Enhance Care) study, a cross-sectional study among 7597 patients with T2DM patients from Belgium, France, Germany, Ireland, Italy, Sweden, the Netherlands and the UK...

Deregulation of mTOR complex 1 (mTORC1) signalling increases the risk for metabolic diseases, including type 2 diabetes. Here we show that β-cell-specific loss of mTORC1 causes diabetes and β-cell failure due to defects in proliferation, autophagy, apoptosis and insulin secretion by using mice with conditional (βraKO) and inducible (MIP-βraKO(f/f)) raptor deletion. Through genetic reconstitution of mTORC1 downstream targets, we identify mTORC1/S6K pathway as the mechanism by which mTORC1 regulates β-cell apoptosis, size and autophagy, whereas mTORC1/4E-BP2-eIF4E pathway regulates β-cell proliferation...

REVIEW
Sigurd Lenzen
Animal models of human type 1 diabetes will be of a great importance for the evaluation of new combination therapies with curative potential. However, reliable predictive power for successful translation to patients with type 1 diabetes is crucial. This will be particularly important in the future when evaluating success of new combination therapies which show great promise for preservation and restoration of beta cell mass and thereby reverse the type 1 diabetic hyperglycaemia. But not all spontaneous animal models are equally well suited for this purpose...

OBJECTIVE: Exposure to unnatural light cycles is increasingly associated with obesity and the metabolic syndrome. The purpose of this study was to examine the effects of electroacupuncture (EA) on glucose metabolism and ovarian function in female rats subjected to long-term continuous light exposure. METHODS: Female Sprague-Dawley rats (n=24) were divided into three experimental groups: an LD group that was maintained under a normal light-dark cycle (healthy control); an LL group that was exposed to continuous light for 21 weeks but remained untreated; and an LL+EA group that received EA at ST36 and SP6 during weeks 17 to 21 of continuous light exposure...

BACKGROUND: Emerging evidence suggests that specific (poly)phenols may constitute new preventative strategies to counteract cell oxidative stress and myocardial tissue inflammation, which have a key role in the patho-physiology of diabetic cardiomyopathy. In a rat model of early diabetes, we evaluated whether in vivo administration of urolithin A (UA) or urolithin B (UB), the main gut microbiota phenolic metabolites of ellagitannin-rich foods, can reduce diabetes-induced microenvironmental changes in myocardial tissue, preventing cardiac functional impairment...

AIMS: Diabetes therapies that provide durable glycaemic control for people with type 2 diabetes mellitus (T2DM) are needed. We present efficacy results of albiglutide, a glucagon-like peptide-1 receptor agonist, in people with T2DM over a 3-year period. METHODS: Five of the 8 HARMONY phase 3 trials, comparing albiglutide with other therapies or placebo across a spectrum of clinical care, lasted for a preplanned 3years. Participants with uncontrolled hyperglycaemia who met predetermined criteria could receive rescue medication...

Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) as progressive form of the disease are associated with cardiovascular risk factors including obesity, dyslipidaemia, hyperglycaemia and hypertension. When NAFLD is associated with cardiovascular disease, mortality of NAFLD patients is increased due to cardiovascular disease. Prevalence of NAFLD and NASH is high, but it seems that epidemic of the disease is under-recognized and under-appreciated. Linking pathophysiological mechanisms are complex and still not well understood...

Type 2 diabetes (T2D) is a complex disease with multiple defects, which generally require a combination of several pharmacological approaches to control hyperglycaemia. Combining a dipeptidyl peptidase-4 inhibitor (DPP-4i) and a sodium-glucose cotransporter type 2 inhibitor (SGT2i) appears to be an attractive approach because the two drugs exert different and potentially complementary glucose-lowering effects. Dual therapy (initial combination or stepwise approach) is more potent than either monotherapy in patients treated with diet and exercise or already treated with metformin...

Induction of endoplasmic reticulum stress and activation of the intrinsic apoptotic pathway is widely believed to contribute to β-cell death in type 1 diabetes (T1D). MCL-1 is an anti-apoptotic member of the BCL-2 protein family, whose depletion causes apoptosis in rodent β-cells in vitro. Importantly, decreased MCL-1 expression was observed in islets from T1D patients. We report here that MCL-1 downregulation is associated with cytokine-mediated killing of human β-cells, a process partially prevented by MCL-1 overexpression...
