Hyperglycaemia in patients receiving enteral or parenteral nutrition is a major problem due to its high prevalence and possible consequences interms of morbidity and mortality. However, the management of diabetes/stress hyperglycaemia during artificial nutrition remains largely unknown,especially in non-critically ill patients. The indications and access routes for artificial nutrition are not different in patients with diabetes/stressdiabetes than in non-diabetics. We do not recommend using enteral formulas designed for patients with diabetes. The glycaemic objective mustbe individualized. We recommend a preprandial blood glucose levels between 100 and 140 mg/dL (5.5 and 7.8 mmol/L) and postprandial levelsbetween 140 and 180 mg/dL (7.8 and 10 mmol/L). A frequent monitoring of capillary glycaemias is mandatory. The best drug treatment for treatinghyperglycaemia/diabetes is insulin and we recommend to adapt the theoretical insulin action to the nutrition infusion regimen. The managementof these patients needs the help of a multidisciplinary experimented staff. [less ▲]

Diabetes mellitus is a common chronic disease in the elderly, being either a known disease with a long history (type 1 or even more often type 2 diabetes) and then frequently associated with various diabetic complications, or a recently diagnosed diabetes that may, however, have been ignored for a rather long time. In this latter case, diabetes may present as the occurrence or aggravation of one or several geriatric syndromes that overall result in a loss of autonomy. The global geriatric assessment, the estimation of life expectancy and the justification of glucose-lowering treatments should be performed at regular intervals in elderly diabetic people as they determine the right choice of glucose target levels and the best selection of glucose-lowering agents. Medications that can induce hypoglycaemia should ideally be avoided, especially in the frailty older population. The benefit-risk ratio of the proposed therapies should be analyzed first, and then regularly reassessed because of a potentially rapidly progressing condition. The recommended approach is a tailored management of diabetes that should integrate the clinical, functional and psycho-social aspects of elderly individuals. [less ▲]

It is recognized that a chronic low-grade inflammation and an activation of the immune system are involved in the pathogenesis of obesity-related insulin resistance and type 2 diabetes. Systemic inflammatory markers are risk factors for the development of type 2 diabetes and its macrovascular complications. Adipose tissue, liver, muscle and pancreas are themselves sites of inflammation in presence of obesity. An infiltration of macrophages and other immune cells is observed in these tissues associated with a cell population shift from an anti-inflammatory to a pro-inflammatory profile. These cells are crucial for the production of pro-inflammatory cytokines, which act in an autocrine and paracrine manner to interfere with insulin signaling in peripheral tissues or induce β-cell dysfunction and subsequent insulin deficiency. Particularly, the pro-inflammatory interleukin-1β is implicated in the pathogenesis of type 2 diabetes through the activation of the NLRP3 inflammasome. The objectives of this review are to expose recent data supporting the role of the immune system in the pathogenesis of insulin resistance and type 2 diabetes and to examine various mechanisms underlying this relationship. If type 2 diabetes is an inflammatory disease, anti-inflammarory therapies could have a place in prevention and treatment of type 2 diabetes. [less ▲]

At home as in the hospital, the diabetic patients are at high risk of malnutrition. In patients with hyperglycemia in artificial nutrition, the primary objective is to to cover their protein needs and their caloric needs and to optimize accordingly the antidiabetic treatment. Insulin therapy is the treatment of choice. The use of low glycaemic index is probably better, especially for oral supplementation. An equivalent parenteral carbohydrate intake has a hyperglycaemic effect more important than with the oral or enteral way. The management of hyperglycemia in artificial nutrition requires defining glycemic goals, tailored to the patient, to the type and the sequences of artificial nutrition, establishing patterns of insulin therapy and providing accurate adaptation rules. Above the basal requirement, insulin therapy sufficient to meet caloric exposure must be prescribed appropriate in timing with the artificial nutrition. The use of sliding scale as monotherapy is ineffective. This management requires forming the nurse team. The acute phase has passed, the disease stabilized, it is sometimes possible to introduce oral antidiabetic drugs and stop insulin. In this case, we apply the same prescription rules to these drugs as for the patient fed orally. [less ▲]

Aims/hypothesis Obesity is a heterogeneous condition comprising both individuals who remain metabolically healthy (MHO) and those who develop metabolic disorders (metabolically unhealthy, MUO). Adipose tissue is also heterogeneous in that its visceral component is more frequently associated with metabolic dysfunction than its subcutaneous component. The development of metabolic disorders is partly mediated by the NLR family pyrin domain containing-3 (NLRP3) inflammasome, which increases the secretion of inflammatory cytokines via activation of caspase-1. We compared the immunological profile and NLRP3 activity in adipose tissue between MUO and MHO individuals. Methods MHO and MUO phenotypes were defined, respectively, as the absence and the presence of the metabolic syndrome. Cellular composition and intrinsic inflammasome activity were investigated by flow cytometry, quantitative RTPCR and tissue culture studies in subcutaneous and visceral adipose tissue from 23 MUO, 21 MHO and nine lean individuals. Results We found significant differences between the three study groups, including an increased secretion of IL-1β, increased expression of IL1B and NLRP3, increased number of adipose tissue macrophages and decreased number of regulatory T cells in the visceral adipose tissue of MUO patients compared with MHO and lean participants. In macrophages derived from visceral adipose tissue, both caspase-1 activity and IL-1β levels were higher in MUO patients than in MHO patients. Furthermore, caspase-1 activity was higher in CD11c+CD206+ adipose tissue macrophages than in CD11c−CD206+ cells. Conclusions/interpretation The MUO phenotype seems to be associated with an increased activation of the NLPR3 inflammasome in macrophages infiltrating visceral adipose tissue, and a less favourable inflammatory profile compared with the MHO phenotype.

The NLRP3 inflammasome is involved in many obesity-associated diseases such as type 2 diabetes, atherosclerosis and gouty arthritis through its ability to induce IL-1β release. The molecular link between obesity and inflammasome activation is still unclear but free fatty acids have been proposed as one triggering event. Here we reported opposite effects of saturated fatty acids (SFAs) compared to unsaturated fatty acids (UFAs) on NLRP3 inflammasome in human monocytes/macrophages. Palmitate and stearate, both SFAs, triggered IL-1β secretion in a caspase-1/ASC/NLRP3-dependent pathway. Unlike SFAs, the UFAs oleate and linoleate did not lead to IL-1β secretion. In addition, they totally prevented the IL-1β release induced by SFAs and, with less efficiency, by a broad range of NLRP3 inducers including nigericin, alum and MSU. UFAs did not affect the transcriptional effect of SFAs suggesting a specific effect on the NLRP3 activation. These results provide a new antiinflammatory mechanism of UFAs by preventing the activation of the NLRP3 inflammasome and therefore the IL-1β processing. By this way, UFAs might play a protective role in NLRP3-associated diseases. [less ▲]

It is a common belief that nutritional deficiencies are rare in the Western world due to a wide variety of food supply. However, obese people usually consume dense-energy food but of poor nutritional value that lacks proteins, vitamins, minerals and fiber; consequently, a high prevalence of micronutrient deficiencies in obese subjects has been reported. Moreover, bariatric surgery has been proven the most effective treatment of morbid obesity, but micronutrient deficiency following bariatric surgery is a major concern, worsening pre-operative nutritional deficiencies. In this article, we reviewed the litterature and highlighted the prevalence of nutritional deficiencies in the morbidly obese population prior to bariatric surgery, clinical consequences of these deficiencies and practical recommendations for these subjects.

Alcoholism is, after smoking, the most common addiction in our society. It is associated with multiple familial, social and professional negative consequences. In addition, alcohol disturbs cellular metabolism and its excessive chronic consumption may lead to multiple dysfunctions that can provoke somatic complications targeting numerous tissues or organs. The present article describes the most important ones involving the liver, the digestive tract, the heart, both the central and peripheral nervous system, and bone marrow. We also discuss the metabolic disturbances associated with chronic alcohol consumption, among which those affecting glucose regulation, lipid profile, uric acid and various vitamins. Finally, we describe the nutritional deficiencies that may be observed in alcoholic people and may contribute to aggravate somatic complications. [less ▲]

In this first article, we focus mainly on the preventive approaches of cardiovascular diseases in patients with prediabetes or (type 1 or type 2) diabetes. The crucial importance of a global multifactorial strategy is emphasized and the target levels of various risk factors are updated. The management of these cardiovascular complications in presence of diabetes will be considered in a second article. [less ▲]

Metformin is unanimously considered as the first-line glucose-lowering agent in type 2 diabetes. Theoretically, however, it cannot be prescribed in a large proportion of patients because of the presence of numerous contraindications corresponding to situations that may increase the risk of lactic acidosis. Recent data suggest that type 2 diabetes patients who are considered as being "at risk" because of the presence of cardiac disease still take benefit from metformin therapy, with a reduction of morbidity and mortality compared with other glucose-lowering agents. The present review analyzes the benefit-risk balance of metformin therapy in special populations, namely patients with stable coronary artery disease, acute coronary syndrome or myocardial infarction, or congestive heart failure.

Type 2 diabetes is characterized by an insulin secretory defect that cannot compensate for insulin resistance. Such relative defect is present in the fasting state (insufficient basal insulin levels) and contributes to overnight hyperglycaemia; it is even more pronounced in the postprandial state when it is then the main responsible factor for hyperglycaemia following meals. An original approach to correct these two disturbances is to propose a therapy combining the injection of a basal insulin (most commonly at bedtime to better control fasting glycaemia) and the administration of an incretin-based medication to potentiate insulin response to the three main meals, without inducing hypoglycaemia. This latter effect can be obtained either by blocking the degradation of incretin hormones with an oral inhibitor of dipeptidyl peptidase-4 (gliptin), or by injecting an agonist of glucagon-like peptide-1 (GLP-1) receptors. These basal insulin-incretin combined therapies are well validated in various controlled trials and observational studies. Lixisenatide is the first GLP-1 receptor agonist being reimbursed in this specific indication of combination with basal insulin in Belgium. [less ▲]
