Abstract
Dunnigan syndrome, or Familial Partial Lipodystrophy type 2 (FPLD2; ORPHA 2348), is a rare autosomal dominant disorder due to pathogenic variants of the LMNA gene. The objective of the French National Diagnosis and Care Protocol (PNDS; Protocole National de Diagnostic et de Soins), is to provide health professionals with a guide to optimal management and care of patients with FPLD2, based on a critical literature review and multidisciplinary expert consensus. The PNDS, written by members of the French National Reference Center for Rare Diseases of Insulin Secretion and Insulin Sensitivity (PRISIS), is available on the French Health Authority website (in French). Dunnigan syndrome is characterized by a partial atrophy of the subcutaneous adipose tissue and by an insulin resistance syndrome, associated with a risk of metabolic, cardiovascular and muscular complications. Its prevalence, assessed at 1/100.000 in Europe, is probably considerably underestimated. Thorough clinical examination is key to diagnosis. Biochemical testing frequently shows hyperinsulinemia, abnormal glucose tolerance and hypertriglyceridemia. Elevated hepatic transaminases (hepatic steatosis) and creatine phosphokinase, and hyperandrogenism in women, are common. Molecular analysis of the LMNA gene confirms diagnosis and allows for family investigations. Regular screening and multidisciplinary monitoring of the associated complications are necessary. Diabetes frequently develops from puberty onwards. Hypertriglyceridemia may lead to acute pancreatitis. Early atherosclerosis and cardiomyopathy should be monitored. In women, polycystic ovary syndrome is common. Overall, the management of patients with Dunnigan syndrome requires the collaboration of several health care providers. The attending physician, in conjunction with the national care network, will ensure that the patient receives optimal care through regular follow-up and screening. The various elements of this PNDS are described to provide such a support.

Abstract
AIM The aim of the present study was to identify the affected gene in a French family with maturity-onset diabetes of the young (MODY) using whole-exome sequencing (WES). METHODS WES was performed in one patient with MODY, and candidate variants were confirmed in members of the immediate family by Sanger sequencing. RESULTS In the proband, a new heterozygous missense mutation (c.340A>C) was identified in the NEUROD1 gene by WES analysis and confirmed by Sanger sequencing. Additional Sanger sequencing of the proband's sister and mother revealed the same heterozygous mutation. The proband and his sister displayed typical clinical characteristics of MODY, while their mother had the same typical MODY features except for later onset. When clinical and biological profiles were established for all three patients, the severity of diabetes-related complications varied substantially from one family member to another. CONCLUSION A novel missense mutation found in NEUROD1 was associated with MODY 6 features in a single French family.

Abstract
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 regularly. Hypothyroidism will be treated using thyroid replacement therapy. Hyperthyroidism imposes a stop of amiodarone when it is possible. Treatment with synthetic antithyroid drugs (propyl-thio-uracil) or corticosteroids could be used whether there is an underlying thyroid disease or not. Immunotherapies with anti-PD-1/PDL1 or anti-CTLA-4 can also provide dysthyroidism. A monitoring of the thyroid assessment needs to be done in these patients, even if there are no clinical signs, which are not very specific in this context. The treatment of hypothyroidism will be based on thyroid replacement therapy according to the TSH level and the presence or absence of anti-TPO antibodies. Treatment of symptomatic hyperthyroidism may involve a prescription of beta-blockers, or synthetic antithyroid drugs in case of positive anti-TSH receptor antibodies. In all cases, it is desirable to contact an endocrinologist to confirm the diagnosis hypothesis and to decide on a suitable treatment.

Abstract
OBJECTIVE The Type A personality, characterized by impatience, strong career ambition and competitiveness, is associated with greater sensitivity to external stress. Type 1 diabetes (T1D) is an auto-immune disease, which is potentially influenced by stress, unlike type 2 diabetes (T2D). The aim of this study was to assess whether individuals with T1D and T2D exhibited significant differences on the Type A personality scale. We also assessed the personality in patients with thyroid auto-immune diseases to validate potential links between auto-immune disease and Type A. DESIGN AND METHODS The Bortner questionnaire was used to assess Type A personality in 188 patients with T1D, 430 patients with T2D and 85 patients with auto-immune thyroid disease (Graves' disease or Hashimoto thyroiditis). RESULTS Type A Bortner scores were significantly higher in T1D patients than in T2D patients (188±34 vs 177±36, p<0.0001). Patients with auto-immune thyroid diseases and T1D patients had similar Type A Bortner scores (189±33 vs 188±34, p=0.860). CONCLUSION Patients with auto-immune T1D have higher Type A scores than T2D patients. Furthermore, patients with auto-immune thyroid disease also have elevated Type A scores similar to those observed in type 1 diabetes, suggesting that an elevated Type A score in T1D is potentially related to its autoimmune origin. This suggests a possible link between Type A personality and auto-immune diseases via stress-triggering psychobiological pathways. The different personality score between T1D and T2D is an important factor to consider that could influence the diabetes self-care coping strategies and long-term prognosis.

Abstract
BACKGROUND In patients with type 2 diabetes (T2D), glycaemic variability (GV), another component of glycaemic abnormalities, is a novel potentially aggravating factor for coronary artery disease (CAD). OBJECTIVES The aim of our study was to identify interactions between GV and severity of CAD in diabetes patients admitted for acute myocardial infarction (AMI). METHODS All patients with T2D admitted to our university hospital for AMI from March 2015 to February 2017 who received intravenous (IV) insulin therapy and underwent coronary angiography were included. GV was assessed by mean amplitude of blood glucose excursion (MAGE) values taken within 2 days of admission. Patients with higher GV (highest MAGE tertile) were compared with those with lower GV (first and second MAGE tertiles). RESULTS A total of 204 patients were included: median age was 72 (61-81) years; 32% were female; HbA1c was 7.3% (6.4-8.2%); diabetes duration was 10 (2-17.5) years; and MAGE value was 0.65 (0.43-0.92) g/L. Compared with those with lower GV, patients with the highest GV were more often women, treated with previous insulin, and had higher blood glucose and HbA1c levels. In addition, patients with elevated GV had significantly higher SYNTAX scores: 17 (10-28) vs. 12 (6-22) (P = 0.009). Indeed, SYNTAX scores (OR: 1.05, 95% CI: 1.02-1.08; P = 0.001) remained independently associated with high GV beyond HbA1c levels (OR: 1.51, 95% CI: 1.2-1.89; P < 0.001). CONCLUSION In AMI patients with poorly controlled diabetes, GV is associated with CAD severity beyond chronic hyperglycaemia. Although no causality can be determined from our observational study, the results suggest that, in AMI, early evaluation of GV might contribute to the identification of those diabetes patients at high risk, and serve as a therapeutic target for both primary and secondary prevention.

Abstract
AIM Protein-energy malnutrition is known to be involved in wound healing. While wound healing in patients with diabetic foot ulcers (DFU) is a complex and multifactorial process, the role of malnutrition in this case has rarely been explored. The objective of this study was to determine whether the nutritional status of diabetic patients influences the healing of DFU. METHODS 48 patients were included in this prospective, single-center study. All patients with comorbidities or factors involving malnutrition or influencing biological measurements were excluded. Patients were followed up for 24 weeks. RESULTS The malnutrition rate was 29.2% at baseline and 25.6% at the end of the study. The difference was not significant. Of the 35 patients with wound healing, 29% were undernourished at inclusion and 17% at the end of the study. Of the 12 patients without wound healing, 50% were undernourished at inclusion, and 42% at the end of the study. These differences were not significant. Rate and speed of wound healing were not associated with malnutrition at inclusion. 15% of patients without malnutrition at baseline had final malnutrition. CONCLUSION We demonstrated that wound healing was not affected by the initial presence of malnutrition. In our study, there is no evidence to support nutritional intervention to improve wound healing in diabetic patients. Nevertheless, malnutrition is responsible for an increase in morbidity and mortality and it is essential to identify malnutrition systematically for all patients with DFU, initially and during follow-up to treat it quickly and efficiently.

Abstract
AIM Type A personality has been associated with increased survival in people with type 1 diabetes (T1D). Systemic low-grade inflammation may play a critical role, as suggested in recent reports, although the links between the inflammatory circulating transcriptome and Type A remain unknown. This prompted our exploration of the potential associations between Type A personality and c-Fos gene expression, a candidate gene closely linked to inflammatory processes, in T1D. METHODS Type A personality was assessed by Bortner questionnaire in patients with T1D, and two subscales - 'speed' and 'competitiveness' - were used to measure these specific dimensions of Type A. Expression of the c-Fos gene was assessed by a quantitative real-time polymerase chain reaction technique. RESULTS This pilot study included 20 men with T1D. Multivariable analyses showed an independent inverse association between Type A competitiveness score and c-Fos expression, while a regression model adjusted for age, body mass index and HbA1c levels revealed a significant inverse relationship between c-Fos transcripts and Type A competitiveness (P = 0.003). CONCLUSION This strong association between Type A competitiveness and reduced c-Fos expression is in line with recent data suggesting a psychobiological influence of the Type A profile in T1D via inflammatory pathways.

Abstract
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.

Abstract
AIMS To evaluate the application of the recently proposed recommendations by the European Association for the Study of the Liver, European Association for the Study of Diabetes and European Association for the Study of Obesity for the diagnosis, treatment and follow-up of non-alcoholic fatty liver disease in people with Type 2 diabetes. METHODS A total of 179 people with Type 2 diabetes were included in this study. Liver fat content (assessed using proton magnetic resonance spectroscopy), fatty liver index score, non-alcoholic fatty liver disease fibrosis score, and SteatoTest and FibroTest scores were determined. RESULTS According to proton magnetic resonance spectroscopy, 68.7% of participants had steatosis (liver fat content >5.5%). The application of the guidelines using several combinations (fatty liver index + non-alcoholic fatty liver disease fibrosis scores, Steatotest + FibroTest scores, proton magnetic resonance spectroscopy + non-alcoholic fatty liver disease fibrosis score, proton magnetic resonance spectroscopy + FibroTest) resulted in a referral to a liver clinic for 33.5-84.9% people with Type 2 diabetes. CONCLUSIONS The application of these new algorithms for the diagnosis, and follow-up of non-alcoholic fatty liver disease would lead to an excessive number of people with Type 2 diabetes being referred to a liver clinic. We suggest that new clinical and/or biological biomarkers of steatosis and fibrosis be specifically validated in people with Type 2 diabetes.

Abstract
The anti-somatostatin agents used to treat acromegaly, Cushing's disease and neuroendocrine tumours also have hyperglycaemic effects. This is particularly true for pasireotide. Hyperglycaemic events are seen in 57-73% of patients with Cushing's treated with pasireotide, with a need to initiate antidiabetic treatment in about 50% of these patients. In acromegaly, treatment with pasireotide induces hyperglycaemia in 29-61% of patients. Pasireotide-induced hyperglycemia occurs early, within the first 3 months of treatment, due to a decrease in insulin secretion secondary to a fall in secretion of GLP-1 and GIP, and potentially also due to a direct inhibitory effect of pasireotide on beta cells. Close monitoring of blood glucose is mandatory in all patients during the first 3 months of treatment with pasireotide. Where necessary, antidiabetic treatment should be initiated, preferably with a DPP-4 inhibitor or a GLP-1 receptor agonist, both of which have proven efficacy in the control of hyperglycaemia induced by pasireotide.

Abstract
INTRODUCTION Apolipoprotein C1 (apoC1) is likely to play an important role in triglyceride (TG) metabolism. Mice overexpressing human apoC1 present decreased adipose tissue stores. This study aimed to determine whether apoC1 concentration influences fat mass and distribution and liver fat content (LFC) in patients with type 2 diabetes (T2D). METHODS ApoC1 concentrations were measured by ELISA in 113 T2D patients and 56 normolipidaemic-normoglycaemic subjects. Visceral and subcutaneous fat areas were determined by single-slice axial T1-weighted magnetic resonance imaging (MRI), while LFC was measured by hydrogen-1 ((1)H) MR spectroscopy. RESULTS ApoC1 concentrations were higher in T2D patients than in normolipidaemic-normoglycaemic subjects (P<0.0001), and did not correlate with visceral or subcutaneous fat areas, but significantly correlated with TG (P<0.0001) and LFC (P=0.02) in T2D patients. However, the correlation between apoC1 and LFC was lost after adjusting for TG. ApoC1 concentration was also significantly higher in T2D patients with TG<1.5mmol/L than in control subjects (P<0.0001), although both groups had similar TG levels. On multivariate analysis performed in T2D patients with TG<1.5mmol/L and control subjects, apoC1 concentration was independently and positively associated with type 2 diabetes (P<0.0001) and TG levels (P=0.03). CONCLUSION This study reports, for the first time, that apoC1 is increased in T2D patients and is significantly correlated with TG, whereas no association was found between apoC1 and adipose tissue. This indicates that, in T2D, apoC1 may play a role in TG metabolism, but is unlikely to modulate fat mass and distribution. This increased apoC1 concentration in T2D patients is not only explained by the increased TG level in T2D patients.

Abstract
BACKGROUND MEN1, which is secondary to the mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Most studies demonstrated the absence of direct genotype-phenotype correlations. The existence of a higher risk of death in the Groupe d'étude des Tumeurs Endocrines-cohort associated with a mutation in the JunD interacting domain suggests heterogeneity across families in disease expressivity. This study aims to assess the existence of modifying genetic factors by estimating the intrafamilial correlations and heritability of the six main tumor types in MEN1. METHODS The study included 797 patients from 265 kindred and studied seven phenotypic criteria: parathyroid and pancreatic neuroendocrine tumors (NETs) and pituitary, adrenal, bronchial, and thymic (thNET) tumors and the presence of metastasis. Intrafamilial correlations and heritability estimates were calculated from family tree data using specific validated statistical analysis software. RESULTS Intrafamilial correlations were significant and decreased along parental degrees distance for pituitary, adrenal and thNETs. The heritability of these three tumor types was consistently strong and significant with 64% (s.e.m.=0.13; P<0.001) for pituitary tumor, 65% (s.e.m.=0.21; P<0.001) for adrenal tumors, and 97% (s.e.m.=0.41; P=0.006) for thNETs. CONCLUSION The present study shows the existence of modifying genetic factors for thymus, adrenal, and pituitary MEN1 tumor types. The identification of at-risk subgroups of individuals within cohorts is the first step toward personalization of care. Next generation sequencing on this subset of tumors will help identify the molecular basis of MEN1 variable genetic expressivity.

Abstract
In type 2 diabetes (T2DM), glycaemic control delays the development and slows the progression of complications. Although there are numerous glucose-lowering agents in clinical use, only approximately half of T2DM patients achieve glycaemic control, while undesirable side-effects, such as hypoglycaemia and body weight gain, often impede treatment in those taking these medications. Thus, there is a need for novel agents and treatment options. Sodium-glucose cotransporter-2 inhibitors (SGLT-2-i) have recently been developed for the treatment of T2DM. The available data suggest a good tolerability profile for the three available drugs - canagliflozin, dapagliflozin and empagliflozin - approved by the US Food and Drug Administration (FDA) for the American market as well as in other countries. The most frequently reported adverse events with SGLT-2-i are female genital mycotic infections, urinary tract infections and increased urination. The pharmacodynamic response to SGLT-2-i declines with increasing severity of renal impairment, requiring dosage adjustments or restrictions with moderate-to-severe renal dysfunction. Most patients treated with SGLT-2-i also have a modest reduction in blood pressure and modest effects on serum lipid profiles, some of which are beneficial (increased high-density lipoprotein cholesterol and decreased triglycerides) and others which are not (increased low-density lipoprotein cholesterol, LDL-C). A number of large-scale and longer-term cardiovascular trials are now ongoing. In patients treated with dapagliflozin, a non-significant excess number of breast and bladder cancers has been reported; considered as due to a bias, this is nevertheless being followed in the ongoing trials. No other significant safety issues have been reported so far. Although there is some benefit for several cardiovascular risk factors such as HbA1c, high blood pressure, obesity and increases in LDL-C, adequately powered trials are still required to determine the effects of SGLT-2-i on macrovascular outcomes.

Abstract
CONTEXT Multiple endocrine neoplasia Type-1 (MEN1) in young patients is only described by case reports. OBJECTIVE To improve the knowledge of MEN1 natural history before 21 years old. METHODS Obtain a description of the first symptoms occurring before 21 years old (clinical symptoms, biological or imaging abnormalities), surgical outcomes related to MEN1 Neuro Endocrine Tumors (NETs) occurring in a group of 160 patients extracted from the "Groupe d'étude des Tumeurs Endocrines" MEN1 cohort. RESULTS The first symptoms were related to hyperparathyroidism in 122 cases (75%), pituitary adenoma in 55 cases (34%), nonsecreting pancreatic tumor (NSPT) in 14 cases (9%), insulinoma in 20 cases (12%), gastrinoma in three cases (2%), malignant adrenal tumors in 2 cases (1%), and malignant thymic-NET in one case (1%). Hyperparathyrodism was the first lesion in 90 cases (56%). The first symptoms occurred before 10 years old in 22 cases (14%) and before 5 years old in five cases (3%). Surgery was performed before age 21 in 66 patients (41%) with a total of 74 operations: pituitary adenoma (n = 9, 16%), hyperparathyroidism (n = 38, 31%), gastrinoma (n = 1, 33%), NSPT (n = 5, 36%), and all cases of insulinoma, adrenal tumors, and thymic-NET. One patient died before age 21 due to a thymic-NET. Overall, lesions were malignant in four cases. CONCLUSIONS Various MEN1 lesions occurred frequently before 21 years old, but mainly after 10 years of age. Rare, aggressive tumors may develop at any age. Hyperparathyroidism was the most frequently encountered lesion but was not always the first biological or clinical abnormality to appear during the course of MEN1.
