2011

Summary Background & aims Non-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, metabolic syndrome and type 2 diabetes. Although dietary fat contributes substantially to the accumulation of liver fat, the role of individual fatty acids in this accumulation is unclear. Objective In this study, we set out to determine whether liver fat content (LFC), was associated with red blood cell fatty acid (RBC-FA) composition in people with type 2 diabetes. Design, settings, and participants One hundred and sixty-two type 2 diabetic patients were included in this study. LFC was measured using 1H-MR Spectroscopy. RBC-FA composition was measured by gas chromatography. Results One…

Liver carbohydrate and lipid metabolism of insulin-deficient mice is altered by trans-10, cis-12 conjugated linoleic acid.

2009

Feeding mice the trans-10, cis-12 (t10c12) conjugated linoleic acid (CLA) isomer is associated with lipodystrophy, insulin resistance, hyperinsulinemia, and liver steatosis. It has been hypothesized that CLA-induced liver steatosis is the result of increased hepatic lipogenesis stimulated by high insulin levels. We studied the effects of a 12-d t10c12CLA treatment (1 g/100 g diet) on liver carbohydrate and lipid metabolism in control and streptozotocin (STZ)-injected mice. STZ mice were characterized by insulin deficiency, hypertriglyceridemia, and depletion of liver triglyceride and glycogen. Remarkably, feeding t10c12CLA to diabetic mice (STZ-CLA) normalized these variables. Reconstitutio…

Liraglutide reduces plasma PCSK9 in patients with type 2 diabetes not treated with statins

2022

Dyslipidaemia in type 2 diabetes mellitus (T2DM), which increases cardiovascular risk, includes abnormal metabolism of low-density lipoproteins (LDL). Our group has recently shown that liraglutide increases LDL catabolism in patients with T2DM and that it reduces the expression of PCSK9 (a major inhibitor of LDL-receptor expression) in vitro and in mice. This prompted us to study the effect of liraglutide on plasma PCSK9 level in patients with T2DM.We studied prospectively 82 patients with T2DM (51 without statins, 31 with statins). Plasma PCSK9 and plasma lipids were measured before and six months after the initiation of a treatment with liraglutide at a dose of 1.2 mg/day.Plasma PCSK9 was…

Acute activation of cannabinoid receptors by anandamide reduces gastrointestinal motility and improves postprandial glycemia in mice.

2015

International audience; The endocannabinoid system (ECS) is associated with an alteration of glucose homeostasis dependent on cannabinoid receptor-1 (CB1R) activation. However, very little information is available concerning the consequences of ECS activation on intestinal glucose absorption. Mice were injected intraperitoneally with anandamide, an endocannabinoid binding both CB1R and CB2R. We measured plasma glucose and xylose appearance after oral loading, gastrointestinal motility, and glucose transepithelial transport using the everted sac method. Anandamide improved hyperglycemia after oral glucose charge whereas glucose clearance and insulin sensitivity were impaired, pointing out so…

2014

Abstract Context: High-density lipoproteins (HDLs) from type 2 diabetic patients are unable to counteract the inhibitory effect of oxidized low-density lipoproteins (ox-LDLs) on vasorelaxation. We hypothesized that glitazones, which improve glycemic control and dyslipidemia, could correct this abnormality. Objectives and Design: We compared the ability of HDL from controls (n = 12) and from type 2 diabetic patients before and after 6 months of treatment with either rosiglitazone (n = 11) or pioglitazone (n = 8) to counteract the inhibitory effect of ox-LDL on vasodilatation of rabbit aorta rings. Results: Rosiglitazone induced a decrease in hemoglobin A1c (7.7% ± 1.1% vs 9.8% ± 1.0%, P = .0…

Apolipoprotein CI is a physiological regulator of cholesteryl ester transfer protein activity in human plasma but not in rabbit plasma

2009

Plasma cholesteryl ester transfer protein (CETP) activity is high in rabbits, intermediate in humans, and nondetectable in rodents. Human apolipoprotein CI (apoCI) was found to be a potent inhibitor of CETP. The aim of this study was to compare the ability of rabbit and human apoCI to modulate the interaction of CETP with HDLs and to evaluate to which extent apoCI contributes to plasma cholesteryl ester transfer rate in normolipidemic humans and rabbits. Rabbit apoCI gene was cloned and sequenced, rabbit and human apoCI were purified to homogeneity, and their ability to modify the surface charge properties and the CETP inhibitory potential of HDL were compared. It is demonstrated that unlik…

2006

In type 1 diabetic patients, the replacement of subcutaneous insulin infusion by intraperitoneal insulin infusion restores the normal physiological gradient between the portal vein and the peripheral circulation, which is likely to modify HDL metabolism. This stable isotope kinetic study was designed to compare HDL apolipoprotein (apo) AI metabolism in seven type 1 diabetic patients first treated by continuous subcutaneous insulin infusion by an external pump and then 3 months after the beginning of intraperitoneal insulin infusion by an implantable pump. Glycaemic control was comparable under subcutaneous and intraperitoneal insulin infusion (HbA1c=7.34+/-0.94% versus 7.24+/-1.00%, NS). HD…

Higher risk of death among MEN1 patients with mutations in the JunD interacting domain: a Groupe d'etude des Tumeurs Endocrines (GTE) cohort study.

2013

International audience; Multiple endocrine neoplasia syndrome type 1 (MEN1), which is secondary to mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Although genotype-phenotype studies have so far failed to identify any statistical correlations, some families harbor recurrent tumor patterns. The function of MENIN is unclear, but has been described through the discovery of its interacting partners. Mutations in the interacting domains of MENIN functional partners have been shown to directly alter its regulation abilities. We report on a cohort of MEN1 patients from the Groupe d'étude des Tumeurs Endocrines. Patients with a…

Simultaneous Inhibition of Peripheral CB1R and iNOS Mitigates Obesity-Related Dyslipidemia Through Distinct Mechanisms.

2020

Diabetic dyslipidemia, characterized by increased plasma triglycerides and decreased HDL cholesterol levels, is a major factor contributing to nonalcoholic steatohepatitis and cardiovascular risk in type 2 diabetes. Activation of the cannabinoid-1 receptor (CB1R) and activation of inducible nitric oxide synthase (iNOS) are associated with nonalcoholic steatohepatitis progression. Here, we tested whether dual-targeting inhibition of hepatic CB1R and iNOS improves diabetic dyslipidemia in mice with diet-induced obesity (DIO mice). DIO mice were treated for 14 days with (S)-MRI-1867, a peripherally restricted hybrid inhibitor of CB1R and iNOS. (R)-MRI-1867, the CB1R-inactive stereoisomer that …

ENDOCRINE SIDE EFFECTS OF ANTI-CANCER DRUGS: Effects of anti-cancer targeted therapies on lipid and glucose metabolism

2014

During the past years, targeted therapies for cancer have been developed using drugs that have significant metabolic consequences. Among them, the mammalian target of rapamycin (mTOR) inhibitors and, to a much lesser extent, the tyrosine kinase inhibitors (TKIs) are involved. mTOR plays a key role in the regulation of cell growth as well as lipid and glucose metabolism. Treatment with mTOR inhibitors is associated with a significant increase in plasma triglycerides and LDL cholesterol. mTOR inhibitors seem to increase plasma triglycerides by reducing the activity of the lipoprotein lipase which is in charge of the catabolism of triglyceride-rich lipoproteins. The increase in LDL cholesterol…

Inability of HDL from abdominally obese subjects to counteract the inhibitory effect of oxidized LDL on vasorelaxation.

2007

Abdominal obesity is associated with a decreased plasma concentration of HDL cholesterol and with qualitative modifications of HDL, such as triglyceride enrichment. Our aim was to determine, in isolated aorta rings, whether HDL from obese subjects can counteract the inhibitory effect of oxidized low density lipoprotein (OxLDL) on endothelium-dependent vasodilation as efficiently as HDL from normolipidemic, lean subjects. Plasma triglycerides were 74% higher (P < 0.005) in obese subjects compared with controls, and apolipoprotein A-I (apoA-I) and HDL cholesterol concentrations were 12% and 17% lower (P < 0.05), respectively. HDL from control subjects significantly reduced the inhibitory effe…

The use of statins in people at risk of developing diabetes mellitus: Evidence and guidance for clinical practice

2014

Reducing low-density lipoprotein cholesterol (LDL-C) levels using statins is associated with significant reductions in cardiovascular (CV) events in a wide range of patient populations. Although statins are generally considered to be safe, recent studies suggest they are associated with an increased risk of developing Type 2 diabetes (T2D). This led the US Food and Drug Administration (FDA) to change their labelling requirements for statins to include a warning about the possibility of increased blood sugar and HbA1c levels and the European Medicines Agency (EMA) to issue guidance on a small increased risk of T2D with the statin class. This review examines the evidence leading to these clai…

2021

OBJECTIVE Dyslipidemia observed in type 2 diabetes (T2D) is atherogenic. Important features of diabetic dyslipidemia are increased levels of triglyceride-rich lipoproteins and small dense LDL particles, which all have apolipoprotein B100 (apoB100) as a major apolipoprotein. This prompted us to study the effect of the GLP-1 agonist liraglutide on the metabolism of apoB100-containing lipoproteins. RESEARCH DESIGN AND METHODS We performed an in vivo kinetic study with stable isotopes (L-[1-13C]leucine) in 10 patients with T2D before and after 6 months of treatment with liraglutide (1.2 mg/day). We also evaluated in mice the effect of liraglutide on the expression of genes involved in apoB100-…

Successful Control of Hypoglycemia with Pasireotide LAR in a Patient with Inappropriate Insulin Secretion

2021

Introduction Inappropriate insulin secretion could be due to several diseases. Nesidioblastosis is characterized by diffuse hyperplasia of pancreatic beta cells, causing organic hypoglycemia. No pancreatic lesions are found on the imaging of patients with this condition. Diazoxide is used as a first-line treatment but can be poorly tolerated because of its side effects, and therapeutic failure is possible. Somatostatin analogues have limited efficacy because of their poor affinity to somatostatin (SST) receptors. Pasireotide is a somatostatin analogue with a much higher affinity to SST receptors, especially SST5, and it could thus be more efficient for treating nesidioblastosis-related hypo…

Obesity interferes with the orosensory detection of long-chain fatty acids in humans

2014

Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…

Chronic Hyperinsulinemia Does Not Increase the Production Rate of High-Density Lipoprotein Apolipoprotein AI

2013

Objective— In vitro studies showed that insulin stimulates the production of apolipoprotein AI (apoAI). Thus, we hypothesized that chronic hyperinsulinemia could contribute to the increase in the production of high-density lipoprotein apoAI that is observed in metabolic syndrome. Approach and Results— We performed an in vivo kinetic study with stable isotope in 7 patients with insulinoma who showed hyperinsulinemia but no insulin resistance, 8 patients with insulin resistance, and 16 controls. Insulinemia was 3.1× ( P &lt;0.01) higher in patients with insulinoma or insulin resistance than in controls in the fasting state and, respectively, 3.5× and 2.6× ( P &lt;0.05) higher in the fed stat…

However, the HbA1c goal is ≥8% for institutionalised patients with treatments that can cause hypoglycaemia.PurposeWe aimed to assess the prevalence of hypoglycaemia with continuous glucose monitoring and to evaluate the link with HbA1C in older institutionalised patients with diabetes taking potentially hypoglycaemia-inducing drugs.DesignProspective, multicentre study carried out in six geriatric care centres in the Côte d’Or region of France between January 2019 and July 2020.Settings, subjects and methodsA FreeStyle Libre Pro® (FSLP) was worn for up to 14 days in blinded mode in 42 patie…

Glycemic Variability Assessment with a 14-Day Continuous Glucose Monitoring System: When and How Long to Measure MAGE (Mean Amplitude of Glucose Excu…

2021

Mean amplitude of glucose excursion (MAGE) is considered as the “gold standard” for assessing the short-term within-day glycemic variability (GV), which is an important component of overall glycemic control. A 14-day continuous glucose monitoring system is now widely used and allows easier assessment of GV. However, it is still unknown whether MAGE, usually calculated on a 48-hour period is identical whatever the time during the 14-day lifespan of the sensor and whether a longer time period might give additional information. We evaluated in 68 patients with type 1 diabetes, MAGE during three 2-day periods (day1-day3; day6-day8; day11-day13) and during periods of 3 days and 4 days. MAGE cal…

Effets de la corticothérapie systémique sur le métabolisme des HDL

2020

Resume La prise exogene de glucocorticoides (GC) est responsable de nombreux effets secondaires, notamment metaboliques. Les effets sur le metabolisme lipidique ne se limitent pas aux triglycerides, mais concernent egalement les HDL. Meme si les donnees disponibles sont peu nombreuses, elles montrent que les GC entrainent une augmentation des taux plasmatiques de HDL-cholesterol et de la taille des particules HDL, independante de l’effet anti-inflammatoire des GC. Les mecanismes sous-jacents a ces augmentations restent actuellement meconnus. Alors que les patients traites par GC presentent une augmentation de la morbidite cardiovasculaire et que l’alteration de la fonctionnalite des HDL est…

Materials and Methods Forty type-2 diabetic patients underwent LMF measurement by 3.0T 1H magnetic resonance spectroscopy (corrected for T1 and T2 decays) as the reference standard and liver fat fraction (%Fat) measurement by four Dual/Triple GRE sequences with 20° and 60° flip angle (α), corrected for T1 recovery. The same four sequences were repeated in eight patients after ferumoxide injection. Corrections for systematic errors…

Glycated albumin with loss of fatty acid binding capacity contributes to enhanced arachidonate oxygenation and platelet hyperactivity: relevance in p…

2014

High plasma concentrations of nonesterified fatty acids (NEFAs), transported bound to serum albumin, are associated with type 2 diabetes (T2D). The effects of albumin on platelet function were investigated in vitro. Modifications of albumin, such as those due to glycoxidation, were found in patients with T2D, and the consequences of these modifications on biological mechanisms related to NEFA handling were investigated. Mass spectrometry profiles of albumin from patients with T2D differed from those from healthy control subjects. Diabetic albumin showed impaired NEFA binding capacity, and both structural and functional alterations could be reproduced in vitro by incubating native albumin wi…

Glycation des HDL et conséquences chez le patient diabétique

2013

Resume Les HDL ont un role majeur dans l’homeostasie vasculaire. Leur action protectrice passe notamment par leur recepteur specifique SR-BI (pour scavenger receptor de classe B type 1 ). La glycation des HDL, phenomene majeur observe au cours d’un diabete, a de nombreuses consequences nefastes vasculaires. La glycation des HDL entraine une augmentation de leur catabolisme, un defaut du transport inverse du cholesterol, une perte de leurs proprietes anti-inflammatoires et anti-oxydantes, notamment sur les LDL oxydees, lipoproteines atherogenes presentes en abondance dans les maladies chroniques. Cliniquement, cela se traduit par une dysfonction endotheliale, phenomene cardiovasculaire delet…

Impact of Fasting Glycemia on Short-Term Prognosis after Acute Myocardial Infarction

2007

The prognosis of patients with acute myocardial infarction (MI), according to the new criteria for impaired fasting glucose (IFG) (FG 100-126 mg/dl), has not been evaluated.A total of 2353 patients with acute MI and surviving at d 5 after admission were analyzed for short-term morbidity and mortality. FG was obtained at d 4 and 5. Patients were classified as diabetes mellitus (known diabetes or FGor = 126 mg/dl), high IFG (110or = FG126 mg/dl), low IFG (100or = FG110 mg/dl), and normal fasting glucose (NFG) (FG100 mg/dl).Among the 2353 patients, 968 (41%) had diabetes mellitus, 262 (11%) had high IFG, 332 (14%) had low IFG, and 791 (34%) had NFG. Compared with NFG patients, 30-d cardiovascu…

Different effects of pioglitazone and rosiglitazone on lipid metabolism in mouse cultured liver explants.

2010

Background Pioglitazone (PIO) and rosiglitazone (ROSI) are widely used as oral antidiabetic agents for treatment of type 2 diabetes. Although these medications exert similar effects on blood glucose, recent clinical studies indicated that PIO has a more pronounced beneficial effect on lipid parameters than ROSI. In order to get further insight into the lipid effects of both drugs, we tested whether PIO, compared to ROSI, could exert direct effects on lipid liver metabolism in relation with plasma lipids. Methods We performed in vitro studies using mice liver slices incubated 21 h either with ROSI (1 µmol/L) or PIO (7.5 µmol/L). Results We showed that both glitazones slightly reduced HMG-CoA…

GLP-1 receptor agonists in NAFLD.

2017

IF 4.101; International audience; Non-alcoholic fatty liver disease (NAFLD) is very common in patients with type 2 diabetes (T2D), with approximately two-thirds having a diagnosis of the disease. Currently, the only validated treatment for NAFLD is weight loss. A number of studies of animal models and human trials have evaluated the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on liver fat content and suggest that the treatment could represent a new alternative for NAFLD management. In this review, our focus is on the main studies regarding the effects of GLP-1RAs on NAFLD. Also, the mechanisms that might explain their beneficial effects on liver diseases are analyzed.

Distinct patterns of heparin affinity chromatography VLDL1 and VLDL2 subfractions in the different dyslipidaemias

2007

Very low density lipoprotein (VLDL) 1 and 2 were fractionated by heparin affinity chromatography into a bound and an unbound fraction and the different subfractions were quantified in 17 normolipidaemic (NL), 13 hypercholesterolaemic (HC), 10 hypertriglyceridaemic (HTG) and 11 combined hyperlipidaemic subjects (CHL). Unbound VLDL1 and VLDL2 were, respectively, 1.9- and 2.2-fold richer in triglycerides than bound VLDL1 and VLDL2. In HTG and CHL the concentration of all the VLDL subfractions was increased and plasma triglyceride level was correlated to unbound VLDL1 and to bound VLDL1 (respectively, r=0.86 (p<0.001) and r=0.77 (p<0.01) in HTG and r=0.73 (p<0.001) and r=0.62 (p<0.05) in CHL). …

Overactivation of the endocannabinoid system alters the antilipolytic action of insulin in mouse adipose tissue.

2017

Evidence has accumulated that obesity-related metabolic dysregulation is associated with overactivation of the endocannabinoid system (ECS), which involves cannabinoid receptor 1 (CB1R), in peripheral tissues, including adipose tissue (AT). The functional consequences of CB1R activation on AT metabolism remain unclear. Since excess fat mobilization is considered an important primary event contributing to the onset of insulin resistance, we combined in vivo and in vitro experiments to investigate whether activation of ECS could alter the lipolytic rate. For this purpose, the appearance of plasma glycerol was measured in wild-type and CB1R−/− mice after acute anandamide administration or inh…

Potential influence of Type A personality on plasma C-reactive protein levels in people with diabetes

2016

IF 4.693; Aim. Type A personality, although classically known as a factor linked to increased vascular risk, has recently been associated with increased survival in patients with diabetes. As low-grade inflammation predicts a poor outcome, the present study explored the potential associations between Type A and plasma levels of C-reactive protein (CRP) in diabetes. Methods. Type A personality was assessed by the Bortner questionnaire in people with diabetes. The association between Type A and plasma CRP levels was examined by multivariable linear regression, and structural equation modelling (SEM) was performed to determine the impact of the major clinical, biological and psychological conf…

Treatment by GLP-1 agonist modulates hedonic response to food and taste sensitivity in type 2 diabetes

2012

Context: Besides their potential action in the treatment of type 2 diabetes mellitus (T2DM), GLP-1 analogues have been shown to decrease satiety and food intake. However, little is known about their effects on food hedonic and taste perceptions. Objective: The objective of the study was to investigate the impact of GLP-1 analogue Liraglutide on the liking and wanting component of the food reward system as well as on taste sensitivity in T2DM patients. . Research design and methods: Thirty T2DM patients were studied before and after 3 months of daily Liraglutide treatment (1.2 mg). In each trial, blood samples were collected and body mass composition was analyzed by dual-energy X-ray absorpt…

French Endocrine Society Guidance on endocrine side effects of immunotherapy.

2018

The management of cancer patients has changed due to the considerably more frequent use of immune checkpoint inhibitors (ICPIs). However, the use of ICPI has a risk of side effects, particularly endocrine toxicity. Since the indications for ICPI are constantly expanding due to their efficacy, it is important that endocrinologists and oncologists know how to look for this type of toxicity and how to treat it when it arises. In view of this, the French Endocrine Society initiated the formulation of a consensus document on ICPI-related endocrine toxicity. In this paper, we will introduce data on the general pathophysiology of endocrine toxicity, and we will then outline expert opinion focusing…

Deleterious effect of glycation on the ability of HDL to counteract the inhibitory effect of oxidized LDL on endothelium-dependent vasorelaxation

2013

Background Contrary to high-density lipoprotein (HDL) from normolipidaemic and normoglycaemic subjects, HDL from diabetic patients loses its ability to reverse the inhibition of vasorelaxation induced by oxidized low-density lipoprotein (LDL). The aim of this study was to analyze the role of glycation, a major abnormality observed in diabetes, on the impairment of the vasorelaxant effect of HDL. Methods HDL from healthy subjects was glycated in vitro by incubation in glucose 200 mmol/L for 3 days. Vasoreactivity was evaluated by the relaxation response to acetylcholine of rabbit aorta rings pre-contracted with noradrenaline, before and after 2 h incubation with or without different lipoprot…

Endocrine side-effects of new anticancer therapies: Overall monitoring and conclusions

2018

IF 0.795 (2017); International audience; The present final consensus statement of the French Society of Endocrinology lays out the assessments that are to be systematically performed before and during anticancer treatment by immunotherapy, tyrosine kinase inhibitors or mTOR inhibitors, even without onset of any endocrinopathy. It also discusses the CTCAE adverse event grading system in oncology and the difficulty of implementing it for endocrine side-effects of these anticancer treatments. Notably, this is why certain treatment steps applied in other side-effects (e.g., high-dose corticosteroids, contraindications to immunotherapy, etc.) need to be discussed before implementation for endocr…

Expert opinion on the metabolic complications of mTOR inhibitors

2018

Abstract Using mTOR inhibitors (mTORi) as anticancer drugs led to hyperglycemia (12–50%) and hyperlipidemia (7–73%) in phase-III trials. These high rates require adapted treatment in cancer patients. Before initiating mTORi treatment, lipid profile screening should be systematic, with fasting glucose assay in non-diabetic patients and HbA1C in diabetic patients. After initiation, lipid profile monitoring should be systematic, with fasting glucose assay in non-diabetic patients, every 2 weeks for the first month and then monthly. The HbA1C target is ≤ 8%, before and after treatment initiation in known diabetic patients and in case of onset of diabetes under mTORi. LDL-cholesterol targets sho…

2018

Objective— Treatment with liraglutide, a GLP-1 (glucagon-like peptide-1) agonist, has been shown to reduce postprandial lipidemia, an important feature of diabetic dyslipidemia. However, the underlying mechanisms for this effect remain unknown. This prompted us to study the effect of liraglutide on the metabolism of ApoB48 (apolipoprotein B48). Approach and Results— We performed an in vivo kinetic study with stable isotopes (D 8 -valine) in the fed state in 10 patients with type 2 diabetes mellitus before treatment and 6 months after the initiation of treatment with liraglutide (1.2 mg/d). We also evaluated, in mice, the effect of a 1-week liraglutide treatment on postload triglycerides an…

Impacts of obesity on the oro-sensory perception of lipids in Human

2010

Accumulating evidences support the existence of a fatty acid taste both in rodents and humans. A recent study performed in lean subjects suggests the existence of a positive correlation between the oro-sensory perception of dietary lipids and body mass index (BMI) in Human. It was extrapolated that obesity might promote overconsumption of fatty foods by decreasing the detection of lipids in oral cavity. To explore this hypothesis, linoleic acid (LA) detection threshold was determined in lean (18>BMI 30, n=29) volunteers using a 3-alternative force choice ascending concentration presentation procedure in conditions known to minimize other sensory cues. A large distribution of LA detection wa…

Large-scale screening of lipase acid deficiency in at risk population

2021

International audience; BACKGROUND: Lysosomal acid lipase deficiency (LALD, OMIM#278000) is a rare lysosomal disorder with an autosomal recessive inheritance. The main clinical manifestations are related to a progressive accumulation of cholesteryl esters, triglycerides or both within the lysosome in different organs such as the liver, spleen, and cardiovascular system. A wide range of clinical severity is associated with LALD including a severe very rare antenatal/neonatal/infantile phenotype named Wolman disease and a late-onset form named cholesteryl ester storage disease (CESD). METHODS: This study aimed to investigate a cohort of at-risk patients (4174) presenting with clinical or biol…

Hormonal and psychological factors linked to the increased thermic effect of food in malnourished fasting anorexia nervosa

2007

In patients with anorexia nervosa (AN), weight gain is lower than that expected from the energy content of the meals. Thus we investigated the thermic effect of food (TEF) in relation to subjective feelings and plasma hormone levels in a group of AN patients.TEF, feelings (14 items), and plasma release of beta-endorphin, ACTH, cortisol, dopamine, and catecholamines were evaluated in 15 AN patients (body mass index, 13.6 +/- 1.2 kg.m(-2)) and in 15 healthy women after three gastric loads (0, 300, 700 kcal) infused by a nasogastric tube in a blind design.In AN, the blind loads induced an energy-dependent increase in TEF (P0.001), which was higher than that observed in healthy women (P0.001). …

Thyroïdites : où en est-on en 2019 ?

2020

Thyroiditis is a frequent and mostly benign disease that can sometimes disrupt the thyroid balance. Their diagnosis, as well as their aetiology, is a necessary step in the management of the patients. Painful thyroiditis includes acute thyroiditis of infectious origin and subacute thyroiditis. The first one can be treated by antibiotics or antifungals depending on the germ found. The second one will be treated with non-steroidal anti-inflammatory drugs or corticosteroids. In cases of Hashimoto's thyroiditis with overt hypothyroidism, replacement therapy with L-thyroxine will be adapted to the TSH level. As amiodarone treatment provides dysthyroidism, the thyroid status should be monitored re…

Increased body fat mass reduces the association between fructosamine and glycated hemoglobin in obese type 2 diabetes patients

2021

Abstract Obesity is increasing in patients with type 2 diabetes. A possible reduced association between fructosamine and glycated hemoglobin (HbA1c) in obese individuals has been previously discussed, but this has never been specifically evaluated in type 2 diabetes, and the potential influence of body fat mass and fat distribution has never been studied. We studied 112 type 2 diabetes patients with assessment of fat mass, liver fat and fat distribution. Patients with body mass index (BMI) above the median (34.9 kg/m2), versus BMI below the median, had a correlation coefficient between fructosamine and HbA1c significantly reduced (r = 0.358 vs r = 0.765). In the whole population, fructosami…
