[Diabetes-related skin lesions : a frequently underdiagnosed problem]. / Lésions cutanées liées au diabète : une problématique souvent sous-diagnostiquée.

Skin disorders are common in diabetes, affecting both patients with type 1 and type 2 diabetes. These cutaneous manifestations can be classified into three categories: dermatoses associated with the presence of diabetes, cutaneous complications of diabetes (acute and chronic) and dermatoses linked to antidiabetic treatments. These conditions vary considerably in terms of severity (from insignificant cosmetic problems to life-threatening) and prevalence (from relatively frequent to rare). Despite the high prevalence of diabetes and associated skin disorders, the dermatological manifestations of diabetes are generally neglected and often under-diagnosed. Failure to diagnose and treat skin disorders at an early stage can lead to clinical worsening, whereas early detection and treatment can reduce the risk of serious complications.

Chez les personnes atteintes d'un diabète de type 1 ou 2, les atteintes cutanées sont fréquentes. Elles peuvent être classées en trois catégories : les dermatoses associées à la présence du diabète, ses complications cutanées (aiguës et chroniques) et les dermatoses liées aux traitements antidiabétiques. Ces atteintes varient considérablement en gravité (allant de préoccupations esthétiques banales à potentiellement mortelles) et en prévalence (relativement fréquentes à rares). Malgré la prévalence élevée du diabète et des atteintes cutanées associées, les manifestations dermatologiques sont généralement négligées et souvent sous-diagnostiquées. L'absence de diagnostic et de traitement à un stade précoce peut entraîner une aggravation clinique dermatologique. La détection et le traitement précoces de ces atteintes peuvent réduire le risque de complications graves.

[Towards a new way to classify diabetes mellitus]. / Vers une nouvelle classification des diabètes.

Precision medicine makes it possible to classify patients into groups on the basis of molecular and genetic biomarkers, as well as clinical characteristics, in order to optimize therapeutic response. For example, several types of type 2 diabetes seem to coexist with classic insulin-dependent, autoimmune type 1 diabetes : diabetes with insulinopenia (generally severe), diabetes linked to aging or obesity (less severe), and diabetes with insulin resistance, whose patients will be those with the most numerous complications, notably macrovascular. In this article, we examine the possibilities offered by this new classification of diabetes with a view to personalized medicine.

La médecine de précision permet de classer les patients en groupes sur la base de biomarqueurs moléculaires et génétiques ainsi que de caractéristiques cliniques afin d'optimiser la réponse thérapeutique. Ainsi, plusieurs types de diabètes de type 2 semblent coexister à côté du classique diabète de type 1, insulinoprive et avec auto-immunité : des diabètes avec insulinopénie (généralement sévères), des diabètes liés au vieillissement ou à l'obésité (moins sévères), et des diabètes avec insulinorésistance dont les patients porteurs seront ceux qui auront le plus de complications, en particulier macrovasculaires. Dans cet article, nous abordons les possibilités offertes par cette nouvelle classification du diabète vers la perspective d'une médecine personnalisée.

Prolonged culture of human pancreatic islets under glucotoxic conditions changes their acute beta cell calcium and insulin secretion glucose response curves from sigmoid to bell-shaped.

AIMS/HYPOTHESIS: The rapid remission of type 2 diabetes by a diet very low in energy correlates with a marked improvement in glucose-stimulated insulin secretion (GSIS), emphasising the role of beta cell dysfunction in the early stages of the disease. In search of novel mechanisms of beta cell dysfunction after long-term exposure to mild to severe glucotoxic conditions, we extensively characterised the alterations in insulin secretion and upstream coupling events in human islets cultured for 1-3 weeks at ~5, 8, 10 or 20 mmol/l glucose and subsequently stimulated by an acute stepwise increase in glucose concentration. METHODS: Human islets from 49 non-diabetic donors (ND-islets) and six type 2 diabetic donors (T2D-islets) were obtained from five isolation centres. After shipment, the islets were precultured for 3-7 days in RPMI medium containing ~5 mmol/l glucose and 10% (vol/vol) heat-inactivated FBS with selective islet picking at each medium renewal. Islets were then cultured for 1-3 weeks in RPMI containing ~5, 8, 10 or 20 mmol/l glucose before measurement of insulin secretion during culture, islet insulin and DNA content, beta cell apoptosis and cytosolic and mitochondrial glutathione redox state, and assessment of dynamic insulin secretion and upstream coupling events during acute stepwise stimulation with glucose [NAD(P)H autofluorescence, ATP/(ATP+ADP) ratio, electrical activity, cytosolic Ca2+ concentration ([Ca2+]c)]. RESULTS: Culture of ND-islets for 1-3 weeks at 8, 10 or 20 vs 5 mmol/l glucose did not significantly increase beta cell apoptosis or oxidative stress but decreased insulin content in a concentration-dependent manner and increased beta cell sensitivity to subsequent acute stimulation with glucose. Islet glucose responsiveness was higher after culture at 8 or 10 vs 5 mmol/l glucose and markedly reduced after culture at 20 vs 5 mmol/l glucose. In addition, the [Ca2+]c and insulin secretion responses to acute stepwise stimulation with glucose were no longer sigmoid but bell-shaped, with maximal stimulation at 5 or 10 mmol/l glucose and rapid sustained inhibition above that concentration. Such paradoxical inhibition was, however, no longer observed when islets were acutely depolarised by 30 mmol/l extracellular K+. The glucotoxic alterations of beta cell function were fully reversible after culture at 5 mmol/l glucose and were mimicked by pharmacological activation of glucokinase during culture at 5 mmol/l glucose. Similar results to those seen in ND-islets were obtained in T2D-islets, except that their rate of insulin secretion during culture at 8 and 20 mmol/l glucose was lower, their cytosolic glutathione oxidation increased after culture at 8 and 20 mmol/l glucose, and the alterations in GSIS and upstream coupling events were greater after culture at 8 mmol/l glucose. CONCLUSIONS/INTERPRETATION: Prolonged culture of human islets under moderate to severe glucotoxic conditions markedly increased their glucose sensitivity and revealed a bell-shaped acute glucose response curve for changes in [Ca2+]c and insulin secretion, with maximal stimulation at 5 or 10 mmol/l glucose and rapid inhibition above that concentration. This novel glucotoxic alteration may contribute to beta cell dysfunction in type 2 diabetes independently from a detectable increase in beta cell apoptosis.

Islets-on-Chip: A Tool for Real-Time Assessment of Islet Function Prior to Transplantation.

Islet transplantation improves metabolic control in patients with unstable type 1 diabetes. Clinical outcomes have been improving over the last decade, and the widely used beta-score allows the evaluation of transplantation results. However, predictive pre-transplantation criteria of islet quality for clinical outcomes are lacking. In this proof-of-concept study, we examined whether characterization of the electrical activity of donor islets could provide a criterion. Aliquots of 8 human donor islets from the STABILOT study, sampled from islet preparations before transplantation, were characterized for purity and split for glucose-induced insulin secretion and electrical activity using multi-electrode-arrays. The latter tests glucose concentration dependencies, biphasic activity, hormones, and drug effects (adrenalin, GLP-1, glibenclamide) and provides a ranking of CHIP-scores from 1 to 6 (best) based on electrical islet activity. The analysis was performed online in real time using a dedicated board or offline. Grouping of beta-scores and CHIP-scores with high, intermediate, and low values was observed. Further analysis indicated correlation between CHIP-score and beta-score, although significance was not attained (R = 0.51, p = 0.1). This novel approach is easily implantable in islet isolation units and might provide means for the prediction of clinical outcomes. We acknowledge the small cohort size as the limitation of this pilot study.

[Place of the insulin pump for the treatment of type 2 diabetic patients]. / Place de la pompe à insuline pour le traitement des patients avec un diabète de type 2.

Continuous subcutaneous insulin infusion devices, commonly called insulin pumps, have been used for the treatment of patients with type 1 diabetes for several years. The benefits on glycemic control and on the quality of life of these patients are clear and well documented in the literature. On the other hand, their use in insulin-requiring patients with type 2 diabetes is less widespread. However, studies have shown that this therapeutic option is safe and effective for this population as well. In all cases, individualized assessment and follow-up by a specialized multidisciplinary care team is necessary to support patients with type 2 diabetes for whom an insulin pump is considered. We propose to describe here the current state of this clinical practice.

Les dispositifs de perfusion sous-cutanée continue d'insuline, communément appelés pompes à insuline, sont utilisés pour le traitement des patients avec un diabète de type 1 (PDT1) depuis plusieurs années. Les bénéfices sur le contrôle glycémique et sur la qualité de vie de ces patients sont clairs et bien documentés dans la littérature. En revanche, leur utilisation chez les patients avec un diabète de type 2 (PDT2) insulino-requérants est moins répandue. Pourtant, des études ont démontré que cette thérapie est également sûre et efficace pour cette population. Dans tous les cas, une évaluation et un suivi individualisé par une équipe de soins multidisciplinaire spécialisée est nécessaire pour accompagner les PDT2 chez qui on considère une pompe à insuline. Dans cet article, nous ferons le point sur l'état actuel de cette pratique clinique.

Real world hypoglycaemia related to glucose variability and Flash glucose scan frequency assessed from global FreeStyle Libre data.

AIM: Flash glucose monitoring provides a range of glucose metrics. In the current study, we aim to identify those that indicate that glycaemic targets can be consistently met and contrast the total (t-CV) and within-day coefficient of variation (wd-CV) to guide the assessment of glucose variability and hypoglycaemia exposure. METHODS: De-identified data from Flash readers were collected. The readers were sorted into 10 equally sized groups of scan frequency followed by quartiles of estimated A1c (eA1c). A similar grouping was performed for the total coefficient of variation (t-CV) and within-day coefficient of variation (wd-CV). In addition, analysis of the association of time below 54 mg/dl and glucose variability measured by t-CV and wd-CV was performed. RESULTS: The dataset included 1 002 946 readers. Readers sorted by 10 equal groups of scan rate and quartiles by eA1c, t-CV and wd-CV represented 25 074 readers per group. The association of lower eA1c with higher time in range and reduced time above range was clear. The correlation of eA1c quartiles and time below range was not consistent. An association between glucose variability and hypoglycaemia was found. Both wd-CV and t-CV were associated with time below range. For achieving the consensus target of <1% time below 54 mg/dl, the associated wd-CV and t-CV values were 33.5% and 39.5%, respectively. CONCLUSIONS: The type of CV reported by the different continuous glucose monitoring systems should be acknowledged. CV <36% might not be adequate to ensure low hypoglycaemia exposure. To our knowledge, the majority of continuous glucose monitoring reports the t-CV. Appropriate thresholds should be used to identify patients that would probably meet time below range targets (t-CV <40% or wd-CV <34%).

[Rapid and ultrarapid insulins: when and how?] / Insulines rapides et ultrarapides : quelles indications et utilités ?

Treatment combining long-acting and short-acting insulins is essential for people with type 1 diabetes, but may become also compulsory in other forms of diabetes in case of insulinopenia. The purpose of short-acting insulins is to mimic physiological insulin secretion in response to carbohydrate intake at meals. There is a delay between the injection and its action, sometimes limiting their use and effectiveness. Ultra-rapid insulins have been developed to more closely approximate the expected insulin response to a meal, through faster absorption. They do not improve diabetes control but allow more flexibility with mealtime injections. These new analogues are also an attractive alternative for use in insulin pumps.

Un traitement combinant insulines lente et rapide est essentiel pour les personnes avec un diabète de type 1, mais peut le devenir dans d'autres formes de diabète en cas d'insulinopénie. Le but des insulines rapides est de mimer la sécrétion physiologique d'insuline en réponse à la prise de glucides aux repas. Il y a un délai entre l'injection et son action, limitant parfois leur usage et leur efficacité. Des insulines ultrarapides ont été développées pour se rapprocher davantage de la réponse insulinique attendue à un repas, grâce à une absorption plus rapide. Elles n'améliorent pas le contrôle du diabète mais permettent plus de flexibilité avec les injections aux repas. Ces nouveaux analogues sont également une alternative intéressante pour une utilisation dans les pompes à insuline.

[Continuous glucose monitoring Respective roles of healthcare professionals and quick interpretation guide]. / Mesure continue du glucose - Rôles respectifs des personnels de santé et guide d'interprétation rapide.

The use of continuous interstitial glucose measurement systems (CGM) has revolutionized the management of patients with diabetes for 15 years. This is true both for professional use (diagnostic CGM) and personal use for patients (therapeutic CGM). The role of health professionals - general practitioners, diabetologists, nurses, dieticians - is important to coordinate, with a specific role for each. The clinical situations are all different and the systematic analysis of the data has ideally to be carried out with the participation of the patient. These devices allow significant improvements in glycemic control, making this technology one of the most important advances in diabetes for many years.

L'utilisation des systèmes de mesure continue du glucose interstitiel (CGM) révolutionne la prise en charge des patients avec diabète depuis 15 ans, cela aussi bien pour l'usage professionnel (CGM diagnostique) que personnel pour le patient avec diabète de type 1 ou 2 (CGM thérapeutique). Le rôle des différents professionnels de la santé ­ médecins, infirmier-ère-s, diététicien-nes ­ est important à coordonner, avec un rôle possiblement spécifique de chacun. Les situations cliniques sont diverses et l'analyse systématique des données doit s'effectuer idéalement avec la participation du patient. Ces dispositifs permettent des améliorations importantes de l'équilibre glycémique faisant de cette technologie l'une des avancées les plus importantes en diabétologie depuis de très nombreuses années.

[Treatment of congestive heart failure in older persons and SGLT2 inhibitors - Having your patient's best interests at heart]. / Traitement de l'insuffisance cardiaque chez la personne âgée et inhibiteurs du SGLT2 - En avoir le cœur net.

The treatment and management of heart failure (HF) are constantly evolving. The latest guidelines recommend the use of SGLT2 inhibitors (SGLT2i) as an integral part to treating HF with reduced ejection fraction (< 40%). However, given that the patients included in these trials do not reflect the heterogeneity of the health of many elderly patients, we recommend basing the therapeutic decision on the patient's state of frailty. If a SGLT2i treatment at a standard dose (10 mg 1x/day) is recommended for robust patients, we suggest initiating treatment at 5 mg 1x/day for vulnerable patients, and then after 1 month increasing the dose to 10 mg 1x/day. Finally, for dependent patients, we recommend therapeutic abstention in the absence of sufficient scientific evidence.

La prise en charge de l'insuffisance cardiaque (IC) est en constante évolution. Les dernières recommandations préconisent l'utilisation des inhibiteurs du SGLT2 (iSGLT2) pour le traitement de l'IC à fraction d'éjection réduite (< 40%). Cependant, les populations des études ne reflètent pas l'hétérogénéité de la population âgée en termes de santé et nous proposons de baser la décision thérapeutique selon la Clinical Frailty Scale : si, pour les patients robustes, un traitement par iSGLT2 à dose standard (10 mg 1 x/jour) est préconisé, nous proposons, pour les patients vulnérables, d'initier le traitement à 5 mg 1 x/jour, puis d'augmenter à 10 mg 1 x/jour après 1 mois. Finalement, pour les patients dépendants, nous recommandons une abstention thérapeutique en l'absence d'évidences scientifiques suffisantes.

Impact of ischemia time on islet isolation success and posttransplantation outcomes: A retrospective study of 452 pancreas isolations.

Many variables impact islet isolation, including pancreas ischemia time. The ischemia time upper limit that should be respected to avoid a negative impact on the isolation outcome is not well defined. We have performed a retrospective analysis of all islet isolations in our center between 2008 and 2018. Total ischemia time, cold ischemia time, and organ removal time were analyzed. Isolation success was defined as an islet yield ≥200 000 IEQ. Of the 452 pancreases included, 288 (64%) were successfully isolated. Probability of isolation success showed a significant decrease after 8 hours of total ischemia time, 7 hours of cold ischemia time, and 80 minutes of organ removal time. Although we observed an impact of ischemia time on islet yield, a probability of isolation success of 50% was still present even when total ischemia time exceeds 12 hours. Posttransplantation clinical outcomes were assessed in 32 recipients and no significant difference was found regardless of ischemia time. These data indicate that although shorter ischemia times are associated with better islet isolation outcomes, total ischemia time >12 hours can provide excellent results in appropriately selected donors.

Ten-year outcomes of islet transplantation in patients with type 1 diabetes: Data from the Swiss-French GRAGIL network.

To describe the 10-year outcomes of islet transplantation within the Swiss-French GRAGIL Network, in patients with type 1 diabetes experiencing high glucose variability associated with severe hypoglycemia and/or with functional kidney graft. We conducted a retrospective analysis of all subjects transplanted in the GRAGIL-1c and GARGIL-2 islet transplantation trials and analyzed components of metabolic control, graft function and safety outcomes over the 10-year period of follow-up. Forty-four patients were included between September 2003 and April 2010. Thirty-one patients completed a 10-year follow-up. Ten years after islet transplantation, median HbA1c was 7.2% (6.2-8.0) (55 mmol/mol [44-64]) versus 8.0% (7.1-9.1) (64 mmol/mol [54-76]) before transplantation (p < .001). Seventeen of 23 (73.9%) recipients were free of severe hypoglycemia, 1/21 patients (4.8%) was insulin-independent and median C-peptide was 0.6 ng/ml (0.2-1.2). Insulin requirements (UI/kg/day) were 0.3 (0.1-0.5) versus 0.5 (0.4-0.6) before transplantation (p < .001). Median (IQR) ß-score was 1 (0-4) (p < .05 when comparing with pre-transplantation values) and 51.9% recipients had a functional islet graft at 10 years. With a 10-year follow-up in a multicentric network, islet transplantation provided sustained improvement of glycemic control and was efficient to prevent severe hypoglycemia in almost 75% of the recipients.

LDHA is enriched in human islet alpha cells and upregulated in type 2 diabetes.

The lactate dehydrogenase isoform A (LDHA) is a key metabolic enzyme that preferentially catalyzes the conversion of pyruvate to lactate. Whereas LDHA is highly expressed in many tissues, its expression is turned off in the differentiated adult ß-cell within the pancreatic islets. The repression of LDHA under normal physiological condition and its inappropriate upregulation under a diabetogenic environment is well-documented in rodent islets/ß-cells but little is known about LDHA expression in human islet cells and whether its abundance is altered under diabetic conditions. Analysis of public single-cell RNA-seq (sc-RNA seq) data as well as cell type-specific immunolabeling of human pancreatic islets showed that LDHA was mainly localized in human α-cells while it is expressed at a very low level in ß-cells. Furthermore, LDHA, both at mRNA and protein, as well as lactate production is upregulated in human pancreatic islets exposed to chronic high glucose treatment. Microscopic analysis of stressed human islets and autopsy pancreases from individuals with type 2 diabetes (T2D) showed LDHA upregulation mainly in human α-cells. Pharmacological inhibition of LDHA in isolated human islets enhanced insulin secretion under physiological conditions but did not significantly correct the deregulated secretion of insulin or glucagon under diabetic conditions.

[New-onset diabetes and novel targeted therapies against cancer]. / Diabète secondaire aux nouvelles thérapies ciblées contre le cancer.

New systemic cancer therapies are increasingly oriented towards specific signaling pathways involved in carcinogenesis. However, these new treatments may lead to disorders of glycemic homeostasis ranging from glucose intolerance, diabetes or the occurrence of severe acute hyperglycemic syndrome due to blockade of certain pathways common to glucose metabolism. This article discusses the estimated frequency of new-onset diabetes, the pathophysiological mechanisms as well as the diagnostic, therapeutic, monitoring and prognostic management of glycemic dysfunction in patients treated with these novel systemic cancer therapies.

Les nouvelles thérapies du cancer sont de plus en plus orientées contre des voies de signalisation spécifiques à la carcinogenèse. Cependant, ces nouveaux traitements peuvent mener à des troubles de l'homéostasie glucidique, allant d'une intolérance au glucose au diabète insulinorequérant, avec une potentielle décompensation aiguë, en raison du blocage de certaines voies communes à l'homéostasie glucidique. Cet article discute de la fréquence estimée de la survenue du diabète, des mécanismes physiopathologiques ainsi que de la prise en charge diagnostique et thérapeutique, de la surveillance et du pronostic de la dysfonction glycémique chez les patients traités par ces nouvelles thérapies contre le cancer.

[Basal insulin therapy in patients with type 2 diabetes]. / Insulinothérapie basale chez les patients diabétiques de type 2.

Insulin therapy, often initiated after hygiene and dietary measures and non-insulin antidiabetics, is part of the treatment of patients with type 2 diabetes. Fear of injections or hypoglycemia often delays its implementation. However, its introduction is recommended in cases of poorly balanced diabetes despite a well-controlled therapeutic escalation but also in cases of acute imbalance. Introduction of insulin therapy requires patient education and close monitoring by the healthcare team. Type of insulin and its titration reduce the incidence of hypoglycemia in patients at risk. The determination of the fasting glycemic target - relative to HbA1c - for the titration of insulin is important to define for an optimal benefit (prevention of secondary complications)/risk (hypoglycemia, weight gain) balance.

L'insulinothérapie, souvent mise en place après les mesures hygiéno-diététiques et les antidiabétiques non insuliniques, fait partie du traitement des patients diabétiques de type 2. La peur des injections ou des hypoglycémies retarde souvent sa mise en place. Cependant, son introduction est recommandée en cas de diabète mal équilibré malgré une escalade thérapeutique bien conduite mais aussi en cas de déséquilibre aigu. L'insulinothérapie implique un enseignement au patient et un suivi rapproché par l'équipe soignante. Le type d'insuline et sa titration progressive permettent de réduire l'incidence des hypoglycémies chez les patients à risque. La détermination de la cible glycémique pour la titration de l'insuline est importante à définir pour une balance bénéfice (prévention des complications secondaires)/risque (hypoglycémie, prise pondérale) optimale.

Precision medicine in the era of artificial intelligence: implications in chronic disease management.

Aberrant metabolism is the root cause of several serious health issues, creating a huge burden to health and leading to diminished life expectancy. A dysregulated metabolism induces the secretion of several molecules which in turn trigger the inflammatory pathway. Inflammation is the natural reaction of the immune system to a variety of stimuli, such as pathogens, damaged cells, and harmful substances. Metabolically triggered inflammation, also called metaflammation or low-grade chronic inflammation, is the consequence of a synergic interaction between the host and the exposome-a combination of environmental drivers, including diet, lifestyle, pollutants and other factors throughout the life span of an individual. Various levels of chronic inflammation are associated with several lifestyle-related diseases such as diabetes, obesity, metabolic associated fatty liver disease (MAFLD), cancers, cardiovascular disorders (CVDs), autoimmune diseases, and chronic lung diseases. Chronic diseases are a growing concern worldwide, placing a heavy burden on individuals, families, governments, and health-care systems. New strategies are needed to empower communities worldwide to prevent and treat these diseases. Precision medicine provides a model for the next generation of lifestyle modification. This will capitalize on the dynamic interaction between an individual's biology, lifestyle, behavior, and environment. The aim of precision medicine is to design and improve diagnosis, therapeutics and prognostication through the use of large complex datasets that incorporate individual gene, function, and environmental variations. The implementation of high-performance computing (HPC) and artificial intelligence (AI) can predict risks with greater accuracy based on available multidimensional clinical and biological datasets. AI-powered precision medicine provides clinicians with an opportunity to specifically tailor early interventions to each individual. In this article, we discuss the strengths and limitations of existing and evolving recent, data-driven technologies, such as AI, in preventing, treating and reversing lifestyle-related diseases.

[Diabetes and COVID-19 infection]. / Diabète et infection à COVID-19.

Based on the epidemiological data currently available, diabetes does not seem to be a risk factor for infection with SARS-CoV-2 but may be associated with a more severe course. Diabetes is extremely common in older patients with co-morbidities who are at risk of unfavorable outcomes. As with any other infection, poorly controlled pre-existing diabetes can promote secondary infections and lead to acute complications related to hyperglycemia, worsened itself by the infection. It is important to advise patients to have enough diabetic equipment and supplies at home, to make regular blood glucose self-tests, and to contact a caregiver immediately in case of glycemic imbalance or signs of infection. Antidiabetic therapy may need adjustments following usual sick day rules. Insulin therapy should be considered to treat any persistent hyperglycemia in patients hospitalized for an acute infection.

D'après les données épidémiologiques actuellement disponibles, le diabète ne semble pas être un facteur de risque d'infection par le SARS-CoV-2. Il est cependant associé à une maladie plus sévère principalement en raison de sa haute prévalence chez les personnes âgées et polymorbides dont l'évolution est plus souvent défavorable. Comme lors de n'importe quelle autre infection, un diabète préexistant, surtout s'il est mal contrôlé, peut favoriser les surinfections et entraîner des complications aiguës liées à l'hyperglycémie, elle-même majorée par l'infection. Il est important de recommander aux patients d'avoir suffisamment de matériel à domicile, d'effectuer des automesures régulières de la glycémie, ainsi que de contacter un soignant immédiatement en cas de déséquilibre glycémique ou d'infection. Le traitement antidiabétique doit être adapté comme habituellement en cas d'infection. Une insulinothérapie doit être envisagée en cas d'hyperglycémie persistante chez tout patient hospitalisé pour une infection aiguë.

[Treatment of type 2 diabetes before, during and after metabolic surgery]. / Traitement du diabète de type 2 avant, pendant et après la chirurgie métabolique.

Metabolic surgery is becoming increasingly important in the treatment of obese and diabetic patients. Its impact is major on immediate post-operative glycemic control and adaptation of anti-diabetic treatments is necessary. Over time, a recurrence of diabetes may be observed and the choice of treatments to be reintroduced must take into account the surgery performed. By discussing pharmacological options during the preoperative, peri-operative and post-operative periods, this article provides a review of the literature on a subject for which few guidelines are currently proposed.

La chirurgie métabolique prend une place toujours plus importante dans l'offre de traitement des patients obèses et diabétiques. Son impact est radical sur l'équilibre glycémique postopératoire immédiat et une adaptation rapide des traitements antidiabétiques est nécessaire. Au fil du temps, une récidive du diabète peut être observée et le choix des traitements à réintroduire doit tenir compte de l'intervention chirurgicale effectuée. En discutant les options pharmacologiques durant les périodes préopératoire, périopératoire et postopératoire, cet article propose une revue de la littérature sur un sujet pour lequel peu de directives sont actuellement proposées.

[Insulin pump treatment: For whom and how to set it up on an outpatient?] / Traitement par pompe à insuline : pour qui et comment le mettre en place en ambulatoire ?

Pump therapy has existed for over 40 years and provides a more flexible delivery of insulin. To date, almost 25% of type 1 diabetic patients have chosen this therapeutic option. In recent years, it has also been offered to patients with type 2 insulin-requiring diabetes. The choice of insulin pump is based on its indication, the patient's preference, lifestyle and knowledge of the disease. A risk of developing ketoacidosis in case of interruption of insulin delivery exists. Its implementation therefore requires a specialized interdisciplinary care team available in case of emergency.

L'insulinothérapie par pompe existe depuis plus de 40 ans et permet une délivrance plus flexible de l'insuline. À ce jour, près de 25% des patients diabétiques de type 1 ont choisi cette option thérapeutique. Depuis quelques années, elle est aussi proposée aux patients diabétiques de type 2 insulino-requérants. Le choix de la pompe à insuline repose sur son indication, la préférence du patient, son style de vie et ses connaissances de la maladie. Un risque de survenue d'acidocétose en cas d'interruption de la délivrance d'insuline existe. Sa mise en place nécessite donc une équipe de soins interdisciplinaire spécialisée et disponible en cas d'urgence.

[Post-transplantation diabetes in kidney transplant: from the diabetologist point of view]. / Diabète post-transplantation rénale: le point de vue du diabétologue.

Post-transplantation diabetes (PTDM) exposes to increased morbidity (cardiovascular or infectious complications, early graft dysfunction) and to a risk of premature death. Recognition of risk factors is essential for early and individualized care. The management of a PTDM requires the use of oral antidiabetic treatments (metformin or DPP4 inhibitors) or GLP1 receptor agonists for their favorable effects on weight and kidney that seem ideal in this context. Corticosteroid-induced diabetes or the rare occurrence of diabetic ketoacidosis require insulin therapy. In the long term, the main objective remains to integrate PTDM treatment in a more comprehensive management, targeting the reduction of cardiovascular risk of vulnerable transplant patients.

Le diabète post-transplantation (PTDM) expose le patient à une morbidité accrue (cardiovasculaire, infectieuse ou dysfonction précoce du greffon), ainsi qu'à un risque de décès prématuré. La reconnaissance des facteurs de risque est primordiale pour une prise en charge précoce et individualisée. La prise en charge d'un PTDM d'apparition progressive recourt à l'utilisation d'antidiabétiques oraux (metformine ou inhibiteurs de la dipeptidyl peptidase 4) ou aux agonistes du récepteur du glucagon-like peptide-1 dont l'effet pondéral et néphroprotecteur semble idéal dans ce contexte. Un diabète cortico-induit ou, plus rare, une acidocétose aiguë seront traités par une insulinothérapie précoce. À long terme, l'objectif reste d'intégrer le traitement du PTDM dans une prise en charge plus globale ciblant la réduction du risque cardiovasculaire de ces patients transplantés fragiles.
