Abstract

Abstract Turner syndrome (TS; ORPHA 881) is a rare condition in which all or part of one X chromosome is absent from some or all cells. It affects approximately one in every 1/2500 liveborn girls. The most frequently observed karyotypes are 45,X (40–50%) and the 45,X/46,XX mosaic karyotype (15–25%). Karyotypes with an X isochromosome (45,X/46,isoXq or 45,X/46,isoXp), a Y chromosome, X ring chromosome or deletions of the X chromosome are less frequent. The objective of the French National Diagnosis and Care Protocol (PNDS; Protocole National de Diagnostic et de Soins) is to provide health professionals with information about the optimal management and care for patients, based on a critical literature review and multidisciplinary expert consensus. The PNDS, written by members of the French National Reference Center for Rare Growth and Developmental Endocrine disorders, is available from the French Health Authority website. Turner Syndrome is associated with several phenotypic conditions and a higher risk of comorbidity. The most frequently reported features are growth retardation with short adult stature and gonadal dysgenesis. TS may be associated with various congenital (heart and kidney) or acquired diseases (autoimmune thyroid disease, celiac disease, hearing loss, overweight/obesity, glucose intolerance/type 2 diabetes, dyslipidemia, cardiovascular complications and liver dysfunction). Most of the clinical traits of TS are due to the haploinsufficiency of various genes on the X chromosome, particularly those in the pseudoautosomal regions (PAR 1 and PAR 2), which normally escape the physiological process of X inactivation, although other regions may also be implicated. The management of patients with TS requires collaboration between several healthcare providers. The attending physician, in collaboration 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 designed to provide such support.

Abstract

Summary: Background: Closed-loop insulin delivery systems are expected to become a standard treatment for patients with type 1 diabetes. We aimed to assess whether the Diabeloop Generation 1 (DBLG1) hybrid closed-loop artificial pancreas system improved glucose control compared with sensor-assisted pump therapy. Methods: In this multicentre, open-label, randomised, crossover trial, we recruited adults (aged ≥18 years) with at least a 2 year history of type 1 diabetes, who had been treated with external insulin pump therapy for at least 6 months, had glycated haemoglobin (HbA1c) of 10% or less (86 mmol/mol), and preserved hypoglycaemia awareness. After a 2-week run-in period, patients were randomly assigned (1:1) with a web-based system in randomly permuted blocks of two, to receive insulin via the hybrid closed-loop system (DBLG1; using a machine-learning-based algorithm) or sensor-assisted pump therapy over 12 weeks of free living, followed by an 8-week washout period and then the other intervention for 12 weeks. The primary outcome was the proportion of time that the sensor glucose concentration was within the target range (3·9–10·0 mmol/L) during the 12 week study period. Efficacy analyses were done in the modified intention-to-treat population, which included all randomly assigned patients who completed both 12 week treatment periods. Safety analyses were done in all patients who were exposed to either of the two treatments at least once during the study. This trial is registered with ClinicalTrials.gov, number NCT02987556. Findings: Between March 3, 2017, and June 19, 2017, 71 patients were screened, and 68 eligible patients were randomly assigned to the DBLG1 group (n=33) or the sensor-assisted pump therapy group (n=35), of whom five dropped out in the washout period (n=1 pregnancy; n=4 withdrew consent). 63 patients completed both 12 week treatment periods and were included in the modified intention-to-treat analysis. The proportion of time that the glucose concentration was within the target range was significantly higher in the DBLG1 group (68·5% [SD 9·4] than the sensor-assisted pump group (59·4% [10·2]; mean difference 9·2% [95% CI 6·4 to 11·9]; p

Abstract

Adjustment of daily hydrocortisone dose on clinical criteria lacks sensitivity for fine tuning. Long term hydrocortisone (HC) over-replacement may lead to increased morbidity and mortality in patients with adrenal insufficiency (AI). Biochemical criteria may help detecting over- or under-replacement but have been poorly evaluated.Multicenter, institutional, pharmacokinetic study on ACTH and cortisol plasma profiles during HC replacement in 27 AI patients compared to 29 matched controls. All AI patients were administered HC thrice daily at doses of 6, 10 and 14 mg/m2/d. Blood samples were drawn hourly from 0800h to 1900h. The main outcome measures were: i) plasma peak cortisol and cortisol area under the curve (AUC) in AI patients compared to controls, ii) correlations between cortisol AUC vs single-point cortisol or ACTH decrease from baseline (ΔACTH) and iii) the predictive value of the two latters for obtaining AI patients' cortisol AUC in the control range.Cortisol peaks were observed 1h after each HC intake and a dose response was demonstrated for cortisol peak and cortisol AUC. The comparison of AI patients' cortisol AUC to controls showed that 81.5% AI patients receiving 6mg/m2/d were adequately replaced, whereas most patients receiving higher doses were over-replaced. The correlation coefficient between 1000h/1400h cortisol concentrations and 0800-1900h cortisol AUC were 0.93/0.88 respectively, whereas the 0800-1200h ΔACTH fairly correlated with 0800-1900h cortisol AUC (R = 0.57). ROC curve analysis indicated that the 1000h and 1400h cortisol concentrations best predicted over-replacement.Patients receiving a 6mg/m2 hydrocortisone daily dose exhibited the most physiological daytime cortisol profile. Single point plasma cortisol correlated with daytime cortisol AUC in AI patients. Although hydrocortisone dose should be currently determined on clinical grounds, our data suggest that single point plasma cortisol may be an adjunct for further hydrocortisone dose adjustment in AI patients.

Abstract

Objectives Gynecomastia may be due to aromatase excess in several diseases such as obesity and cancer. Aromatase excess syndrome (AEXS) is an autosomal dominant disorder caused by overexpression of CYP19A1. Germinal mutations occurring in AEXS include various genomic rearrangements including duplication, deletion, and inversion identified in the upstream region of CYP19A1. Aromatase overexpression caused by a CYP19A1 somatic mutation has been rarely described. Methods Breast adipose tissue biopsies or surgical specimens were obtained from 19 subjects with gynecomastia. Aromatase quantification was performed by digital PCR and CYP19A1 sequencing by RACE PCR products. Results We observed localized aromatase overexpression (>10 fold greater than normal) in breast adipose tissue from three prepubertal males with gynecomastia out of the 19 cases. One carried a chromosomal rearrangement between CYP19A1 and DMXL2, consistent with AEXS. In the 2 others, the first exon of CYP19A1 contained 11 different tissue-specific promoter subtypes, specifically I.4 or I.3 normally expressed by adipose tissue, but also the placental I.2 promoter and the more ubiquitous I.7 which is usually expressed in breast cancer, uterine, and endothelial tissues. No differences in clinical or biochemical characteristics were observed between these 3 subjects and 16 others without aromatase overexpression. Conclusions We describe two cases of aromatase overexpression in breast adipose tissue associated with nonspecific promoter recruitment. Further investigations are necessary to understand the mechanisms involved in aberrant promoter selection.

Abstract

International audience; Cushing's syndrome is defined by prolonged exposure to glucocorticoids, leading to excess morbidity and mortality. Diagnosis of this rare pathology is difficult due to the low specificity of the clinical signs, the variable severity of the clinical presentation, and the difficulties of interpretation associated with the diagnostic methods. The present consensus paper by 38 experts of the French Society of Endocrinology and the French Society of Pediatric Endocrinology and Diabetology aimed firstly to detail the circumstances suggesting diagnosis and the biologic diagnosis tools and their interpretation for positive diagnosis and for etiologic diagnosis according to ACTH-independent and -dependent mechanisms. Secondly, situations making diagnosis complex (pregnancy, intense hypercortisolism, fluctuating Cushing's syndrome, pediatric forms and genetically determined forms) were detailed. Lastly, methods of surveillance and diagnosis of recurrence were dealt with in the final section.

Abstract

Context Cortisol-lowering drugs may not restore a normal cortisol secretion in Cushing disease (CD). Objective This work aimed to assess the long-term cortisol exposure in medically treated CD patients using hair-cortisol (HF) and hair-cortisone (HE) measurement. Methods This multicenter prospective study included 3 groups of female patients: CushMed = 16 treated with a stable cortisol-lowering drug dosage and normal urinary free cortisol (UFC); CushSurg = 13 cured by pituitary surgery; CushBla = 15 receiving stable recommended doses of hydrocortisone following bilateral adrenalectomy. Patients were evaluated for 3 months with their usual treatments. Two late-night saliva and 24-hour urine samples were collected monthly in CushMed, and at study end in CushSurg and CushBla patients. A 3-cm hair sample was collected at study end from all patients. Main outcome measures included clinical score and centralized measurement of UFC, late-night salivary cortisol (LNSF), late-night salivary cortisone (LNSE), HE, HF. Results Despite having almost all UFCs normalized, CushMed patients exhibited increased HE as compared to CushSurg controls (P = .003). CushMed patients also had increased clinical score (P = .001), UFC (P = .03), LNSF, LNSE (P = .0001), and variability in the latter parameters (P = .004). CushBla patients had increased HF and HE, contrasting with LNSEs similar to CushSurg patients. Six of 15 CushMed patients exhibited increased HE concentrations and had increased antihypertensive drug dosage compared to CushMed patients with normal HE (P = .05). Conclusion Despite normalized UFCs, a subset of medically treated CD patients displays an altered circadian rhythm of serum cortisol. A single HE measurement identifies chronic mild persistent hypercortisolism and could replace multiple saliva analyzes to monitor medical treatments in CD patients once UFC is normalized.

Abstract

Innovations in syringe and pen needle (PN) technology over the last 100 years have led to important advances in insulin delivery for people with diabetes, paralleling the strides made in developing recombinant DNA human insulin and insulin analogs with varying onset and duration of action. In this review, the history of advances in insulin delivery is described, focusing on progress in syringe, needle, and PN technologies. The early glass and metal syringes that required sterilization by boiling have been replaced by disposable, single-use syringes or pens with clear labeling for precise insulin dosing. The early needles ranging in length from 19 to 26 mm that required manual sharpening against a whetstone have been replaced by syringe needles of 6 mm and PNs of 4 mm in length as slender as 34 gauge. Imaging studies using ultrasound and computed tomography measured the thickness of skin and subcutaneous tissue layers to show feasibility of targeted insulin administration with shorter needles. These developments, coupled with innovations in needle/PN wall and tip structure, have led to improved injection experience for people with diabetes. It is also important to acknowledge the role of injection technique education, together with these advances in injection technology, for improving clinical outcomes and patient satisfaction. With continued projected growth of diabetes prevalence, particularly in developing countries where expensive and complex insulin delivery systems may not be practical, insulin syringes and pens will continue to serve as reliable and cost-effective means of insulin delivery for people with diabetes.

Abstract

Context Prospective studies have demonstrated the efficacy of osilodrostat in Cushing disease. No study has evaluated osilodrostat in a series of patients with paraneoplastic Cushing syndrome/ectopic adrenocorticotropin syndrome (PNCS/EAS). Objective This work aimed to evaluate in France the real-world efficacy and safety of osilodrostat in patients with PNCS/EAS. Methods A total of 33 patients with PNCS/EAS with intense/severe hypercortisolism were involved in this retrospective, multicenter, real-world study. Patients received osilodrostat between May 2019 and March 2022 at a median initial dose (range) of 4 mg/day (1-60) and maximum dose, 20 mg/day (4-100), first under patient then cohort temporary authorizations and after marketing authorization. Regimens used titration (n = 6), block and replace (n = 16), or titration followed by block and replace (n = 11). Results In 11 patients receiving osilodrostat as first-line monotherapy, median 24-hour urinary free cortisol (24h-UFC) decreased dramatically (from 26 × upper limit of normal [ULN; 2.9-659] to 0.11 × ULN [0.08-14.9]; P < .001). In 9 of them, 24h-UFC normalization was achieved in 2 weeks (median). Thirteen additional patients were previously treated with classic steroidogenesis inhibitors but 10 of these 13 were not controlled. In these patients, osilodrostat monotherapy, used as second line, induced a significantly decreased of 24h-UFC (from 2.6 × ULN [1.1-144] to 0.22 × ULN [0.12-0.66]; P < .01). Nine additional patients received osilodrostat in combination with another anticortisolic drug, decreasing 24h-UFC from 11.8 × ULN (0.3-247) to 0.43 × ULN (0.33-2.4) (P < .01). In parallel, major clinical symptoms/comorbidities improved dramatically with improvement in blood pressure, hyperglycemia, and hypokalemia, allowing the discontinuation or dose reduction of patient treatments. Adrenal insufficiency (grade 3-4) was reported in 8 of 33 patients. Conclusion Osilodrostat is a rapidly efficient therapy for PNCS/EAS with severe/intense hypercortisolism. Osilodrostat was generally well tolerated; adrenal insufficiency was the main side effect.

Abstract

Objective Using real-world data from patients with growth hormone deficiency (GHD), we evaluated whether clinical practice in France adheres to international guidelines regarding somatropin dose adjustment, and assessed the long-term effectiveness and safety of somatropin. Methods Data were obtained from a national prospective systematic longitudinal routine follow-up programme of naive/non-naive adults with childhood-onset (CO) or adult-onset (AO) GHD treated with Norditropin® (Novo Nordisk A/S). Results Between 2003 and 2006, 331 treatment-naive and non-naive adults with severe GHD were enrolled and followed for a median duration of approximately 5 years; 328 patients were available for analysis. At baseline, mean patient age was 39.2 years; median standard deviation score (SDS) for insulin-like growth factor−1 (IGF-1) level was −2.2 in naive patients, subsequently fluctuating between −0.1 and +0.3 SDS during the study period. Mean GH doses ranged between 0.25 and 0.51 mg/day (naive patients) and 0.39 and 0.46 mg/day (non-naive patients). Despite generally receiving a higher somatropin dose, women (naive/non-naive) tended to have lower IGF-1 levels than men. Median somatropin dose was consistently higher in patients with CO-GHD than patients with AO-GHD. Extreme IGF-1 values ( + 2 SDS) were not systematically accompanied by somatropin dose adjustments. Waist circumference improved in approximately one third of patients, at a mean 3.5 years. Somatropin was well tolerated; there were no cardiovascular or cerebrovascular events during the 5-year analysis period. Conclusion Current clinical practice of physicians in France follows international guidelines regarding somatropin dose adjustment in adults with GHD. However, dose adjustments are not always sufficient, notably in women, and treatment effects may have been delayed due to low somatropin dose (Clinical trial registration NCT01580605 ).

Abstract

International audience; ObjectiveFamilial hypocalciuric hypercalcaemia type 1 (FHH1), related to heterozygous loss‐of‐function mutations of the calcium‐sensing receptor gene, is the main differential diagnosis for primary hyperparathyroidism. The aim of our study was to describe clinical characteristics of adult patients living in France with a genetically confirmed FHH1.Design and patientsThis observational, retrospective, multicentre study included 77 adults, followed up in 32 clinical departments in France, with a genetic FHH1 diagnosis between 2001 and 2012.ResultsHypercalcaemia was diagnosed at a median age of 53 years [IQR: 38‐61]. The diagnosis was made after clinical manifestations, routine analysis or familial screening in 56, 34 and 10% of cases, respectively, (n = 58; data not available for 19 patients). Chondrocalcinosis was present in 11/51 patients (22%), bone fractures in 8/56 (14%) and renal colic in 6/55 (11%). The median serum calcium was 2.74 mmol/L [IQR: 2.63‐2.86 mmol/L], the median plasma parathyroid hormone level was 4.9 pmol/L [3.1‐7.1], and the median 24‐hour urinary calcium excretion was 2.8 mmol/24 hours [IQR: 1.9‐4.0]. Osteoporosis (dual X‐ray absorptiometry) or kidney stones (renal ultrasonography) were found in 6/38 patients (16%) and 9/32 patients (28%), respectively. Fourteen patients (18%) underwent parathyroid surgery; parathyroid adenoma was found in three patients (21%) and parathyroid hyperplasia in nine patients (64%). No correlation between genotype and phenotype was established.ConclusionThis large cohort study demonstrates that FHH1 clinical characteristics can be atypical in 33 patients (43%). Clinicians should be aware of this rare differential diagnosis in order to adopt an appropriate treatment strategy.

However, adherence to and persistence in support programs are often low, making it difficult to demonstrate their effectiveness.Aim: To identify the determinants of patients’ perceived interest in diabetes support programs because it may be a powerful determinant of effective participation in such programs.Patients and Methods: An online study conducted in April 2021 in metropolitan France on 600 people with diabetes recruited from a consumer panel. A 64-item psychosocial questionnaire including a question asking to evaluate the helpfulness of a support program was used. Univariate, multivariate, and multiple correspondence analyses were performed.Results: The existence of a typology, known as Unsafe/Safe, was discovered, in which patients with type 2 diabetes respond in two distinct ways. Type U (unsafe) patients, who believe that a support program would be helpful, are more likely to be nonadherent to their treatment, have high hemoglobin A1c levels, have at least one diabetic complication, lack information regarding their disease and treatment, rate the burden of their disease and impairment of their quality of life as high, worry about their future, and are pessimistic. Type S (safe) patients have the opposite characteristics. Type U patients can be dichotomized into two broad classes: one in which they lack information regarding disease and treatment and the other in which alterations in the quality of life and burden of the disease predominate. Insulin-treated patients give more importance to the lack of information, whereas noninsulin-treated patients complain primarily about the burden of the disease and impairment of quality of life.Conclusion: This study describes this new U/S typology, proposes a simple method based on a nine-item questionnaire to identify type U patients by calculating a Program Helpfulness Score described herein, and clarifies the nature of the intervention to be provided to them. This novel approach could be applied to other chronic diseases.Keywords: type 2 diabetes, adherence, support programs, typology, personality traits, clinical outcomes, patients’ expectations

Abstract

International audience; Objective: To study the diagnostic yield, including variants in genes yet to be incriminated, of whole exome sequencing (WES) in familial cases of premature ovarian insufficiency (POI). Design: Cross-sectional study. Setting: Endocrinology and reproductive medicine teaching hospital departments. Patients: Familial POI cases were recruited as part of a nationwide multicentric cohort. A total of 36 index cases in 36 different families were studied. Fifty-two relatives were available, including 25 with POI and 27 affected who were nonaffected. Karyotype analysis, FMR1 screening, single nucleotide polymorphism array analysis, and WES were performed in all subjects. Interventions: None. Main Outcome Measures: The primary outcome was a molecular etiology, as diagnosed by karyotype, FMR1 screening, single nucleotide polymorphism array, and WES. Results: A likely molecular etiology (pathogenic or likely pathogenic variant) was identified in 18 of 36 index cases (50% diagnostic yield). In 12 families, we found a pathogenic or likely pathogenic variant in a gene previously incriminated in POI, and in 6 families, we found a pathogenic or likely pathogenic variant in new candidate genes. Most of the variants identified were located in genes involved in cell division and meiosis (n = 11) or DNA repair (n = 4). Conclusions: The genetic etiologic diagnosis in POI allows for genetic familial counseling, anticipated pregnancy planning, and ovarian tissue preservation or oocyte preservation. Identifying new genes may lead to future development of therapeutics in reproduction based on disrupted molecular pathways. Clinical Trial Registration Number: NCT 01177891.

Abstract

Diabetes is a growing health concern. An update on epidemiology and health outcomes is mandatory to devise strategies to alleviate the burden of diabetes. The objective of this study was to assess the prevalence of diabetes and associated complications in France in 2017.Demographics and healthcare data from a representative permanent secondary database were analyzed. Patients with at least 2 national health insurance payments for anti-diabetic drugs in 2017 were selected, with the index date set to the last payment date. Patients were grouped as diabetes treated with insulin only (DTi), diabetes treated with anti-diabetic drugs other than only insulin (DT2) or gestational diabetes. Comorbidities, diabetes-related complications and hospital admissions, healthcare consumption and medical follow-up were extracted for a 5- or 2-year period prior to the index date and summarized using descriptive statistics.Overal, 29,288 patients were included in the study population: 1964 (6.7%) were categorized as DTi and 27,243 (93.0%) as DT2. Patients with gestational diabetes (81 [0.3%]) are not further described here. Prevalence was estimated at 4.9%. For DT2, marked geographic disparities were observed, with prevalence being highest in the northeast France. Diabetes-related complications were more frequent in DTi than in DT2 over a 5-year period (52.2% vs 34.7%). Diabetes-related admissions were also more common in DTi than in DT2 over a 2-year period (29.8% vs 16.9%). In the DT2 category, another antidiabetic drug was added during the 3 months prior to the index date in 16.5% of cases overall and in 25% of patients with recent hospital admission or diabetes-related complications. Although more than 80% of patients in the DTi and DT2 categories had at least 1 healthcare consultation during 2 years prior to the index date, only 10% to 20% of patients complied with guidelines for all 5 recommended examinations.Prevalence of diabetes is high in the French population, while compliance with recommended healthcare consultations falls short of the 80% goal set by regulations. New strategies are mandatory in order to reduce the burden of diabetes-related complications and admissions, focusing on patient and physician information and education in order to increase proactive treatment adjustment and reduce therapeutic inertia.

Abstract

Aims To compare closed-loop (CL) and open-loop (OL) systems for glycaemic control in patients with type 1 diabetes (T1D) exposed to real-life challenging situations (gastronomic dinners or sustained physical exercise). Methods Thirty-eight adult patients with T1D were included in a three-armed randomized pilot trial (Diabeloop WP6.2 trial) comparing glucose control using a CL system with use of an OL device during two crossover 72-hour periods in one of the three following situations: large (gastronomic) dinners; sustained and repeated bouts of physical exercise (with uncontrolled food intake); or control (rest conditions). Outcomes included time in spent in the glucose ranges of 4.4-7.8 mmol/L and 3.9-10.0 mmol/L, and time in hypo- and hyperglycaemia. Results Time spent overnight in the tight range of 4.4 to 7.8 mmol/L was longer with CL (mean values: 63.2% vs 40.9% with OL; P ≤ .0001). Time spent during the day in the range of 3.9 to 10.0 mmol/L was also longer with CL (79.4% vs 64.1% with OL; P ≤ .0001). Participants using the CL system spent less time during the day with hyperglycaemic excursions (glucose >10.0 mmol/L) compared to those using an OL system (17.9% vs 31.9%; P ≤ .0001), and the proportions of time spent during the day with hyperglycaemic excursions of those using the CL system in the gastronomic dinner and physical exercise subgroups were of similar magnitude to those in the control subgroup (18.1 ± 6.3%, 17.2 ± 8.1% and 18.4 ± 12.5%, respectively). Finally, times spent in hypoglycaemia were short and not significantly different among the groups. Conclusions The Diabeloop CL system is superior to OL devices in reducing hyperglycaemic excursions in patients with T1D exposed to gastronomic dinners, or exposed to physical exercise followed by uncontrolled food and carbohydrate intake.

Abstract

Paraneoplastic Cushing’s syndrome (PCS) is frequently caused by neuroendocrine tumours (NETs). Approximately 20% of tumours are still occult years later. Gallium-68 somatostatin receptor-PET/CT is promising for the detection of the causal primary NET, but its role in case of recurrent PCS is rarely reported. We report our experience with DOTATOC PET/CT in localising the causal NET in cases of initial but also recurrent PCS, and its clinical impact. A retrospective review of all DOTATOC PET/CTs performed in consecutive patients referred for PCS to our centre, between January 2011 and June 2017, was done. Nineteen patients underwent 26 PET/CTs, 13 for detection of a primary NET, seven for persistent or recurrent PCS after resection, and six for surveillance after resection of NETs previously detected on a DOTATOC PET/CT in our centre. Among the 13 PET/CTs performed to search for primary NET, five were positive: four carcinoid lung tumours were confirmed after resection and one lung focus was not confirmed since surgery would have carried a high risk. Clinical impact was 23% (3/13). Among the seven PET/CTs performed for persistent or recurrent PCS, six were true-positive, with confirmation of metastatic lymph nodes after resection. Clinical impact was 57% (4/7). All PET/CTs performed for surveillance were true-negative. DOTATOC PET/CT seems to be a valuable tool for detection of the NET responsible for persistent or recurrent PCS after surgery. In this context, DOTATOC PET/CT was more effective than for the detection of the causal tumour in initial PCS.

Abstract

PolyCystic Ovary Syndrome (PCOS) is the first endocrinopathy of women of child-bearing age and the leading cause of anovulatory infertility. The pathophysiology of this syndrome is complex and involves genetic traits highlighted by GWAS and epigenetic traits with DNA methylation modifications. Initially described as an ovarian disease, works carried out over recent years were turned towards neuroendocrine disorder involving GABAergic pathways, KNDy neurons and a possible role of prenatal androgen exposure determined by animal models. Clinically, PCOS leads to many complications including psychological and emotional disorders demonstrated in large populations of PCOS women. © 2019 Published by Elsevier Masson SAS.

Abstract

TeleDiab‐2 was a 13‐month randomized controlled trial evaluating the efficacy and safety of two telemonitoring systems to optimize basal insulin (BI) initiation in subjects with inadequately controlled type 2 diabetes (HbA1c, 7.5%‐10%). A total of 191 participants (mean age 58.7 years, mean HbA1c 8.9%) were randomized into three groups: group 1(G1, standard care, n = 63), group 2 (G2, interactive voice response system, n = 64) and group 3 (G3, Diabeo‐BI app software, n = 64). The two telemonitoring systems proposed daily adjustments of BI doses, in order to facilitate the achievement of fasting blood glucose (FBG) values targeted at ~100 mg/dL. At 4 months follow‐up, HbA1c reduction was significantly higher in the telemonitoring groups (G2: −1.44% and G3: −1.48% vs. G1: −0.92%; P

Abstract

Summary: Background: Closed-loop insulin delivery systems are expected to become a standard treatment for patients with type 1 diabetes. We aimed to assess whether the Diabeloop Generation 1 (DBLG1) hybrid closed-loop artificial pancreas system improved glucose control compared with sensor-assisted pump therapy. Methods: In this multicentre, open-label, randomised, crossover trial, we recruited adults (aged ≥18 years) with at least a 2 year history of type 1 diabetes, who had been treated with external insulin pump therapy for at least 6 months, had glycated haemoglobin (HbA1c) of 10% or less (86 mmol/mol), and preserved hypoglycaemia awareness. After a 2-week run-in period, patients were randomly assigned (1:1) with a web-based system in randomly permuted blocks of two, to receive insulin via the hybrid closed-loop system (DBLG1; using a machine-learning-based algorithm) or sensor-assisted pump therapy over 12 weeks of free living, followed by an 8-week washout period and then the other intervention for 12 weeks. The primary outcome was the proportion of time that the sensor glucose concentration was within the target range (3·9–10·0 mmol/L) during the 12 week study period. Efficacy analyses were done in the modified intention-to-treat population, which included all randomly assigned patients who completed both 12 week treatment periods. Safety analyses were done in all patients who were exposed to either of the two treatments at least once during the study. This trial is registered with ClinicalTrials.gov, number NCT02987556. Findings: Between March 3, 2017, and June 19, 2017, 71 patients were screened, and 68 eligible patients were randomly assigned to the DBLG1 group (n=33) or the sensor-assisted pump therapy group (n=35), of whom five dropped out in the washout period (n=1 pregnancy; n=4 withdrew consent). 63 patients completed both 12 week treatment periods and were included in the modified intention-to-treat analysis. The proportion of time that the glucose concentration was within the target range was significantly higher in the DBLG1 group (68·5% [SD 9·4] than the sensor-assisted pump group (59·4% [10·2]; mean difference 9·2% [95% CI 6·4 to 11·9]; p

Abstract

Background . To evaluate the impact of switching from U-100 to U-500 insulin in patients with type 2 diabetes mellitus (T2DM) uncontrolled with continuous subcutaneous insulin infusion (CSII) by pump. Methods We retrospectively collected data from patients with T2DM, treated by U-100 CSII, who were switched to U-500 regular insulin where haemoglobin A1c (HbA1c) was >8% and/or insulin total daily dose (TDD) was >100 UI/d. Data collection from patient medical records included HbA1c, lipid levels, liver biomarkers, weight, TDD, declared hypoglycaemic episodes and measured by continuous glucose monitoring (CGM). Results Sixty-five patients were included, aged 63.9 ± 8.6 years, insulin pump since 3.7 ± 3 years, TDD 186 ± 52 U/day, body mass index 39.4 ± 5.3 kg/m², HbA1c 9.03 ± 1.6%. After switching to U-500 insulin, HbA1c dropped by -0.96% (P Conclusions U-100 to U-500 insulin switch improves glucose control in CSII T2DM patients, especially with high baseline HbA1c. Use of concentrated insulin in pumps may represent an advance in the strategy for treating T2DM insulin resistant states with uncontrolled hyperglycaemia after a switch from multiple daily injections to pump therapy.

Abstract

Objective Male sex is one of the determinants of severe coronavirus diseas-e-2019 (COVID-19). We aimed to characterize sex differences in severe outcomes in adults with diabetes hospitalized for COVID-19. Methods We performed a sex-stratified analysis of clinical and biological features and outcomes (i.e. invasive mechanical ventilation (IMV), death, intensive care unit (ICU) admission and home discharge at day 7 (D7) or day 28 (D28)) in 2380 patients with diabetes hospitalized for COVID-19 and included in the nationwide CORONADO observational study (NCT04324736). Results The study population was predominantly male (63.5%). After multiple adjustments, female sex was negatively associated with the primary outcome (IMV and/or death, OR: 0.66 (0.49–0.88)), death (OR: 0.49 (0.30–0.79)) and ICU admission (OR: 0.57 (0.43–0.77)) at D7 but only with ICU admission (OR: 0.58 (0.43–0.77)) at D28. Older age and a history of microvascular complications were predictors of death at D28 in both sexes, while chronic obstructive pulmonary disease (COPD) was predictive of death in women only. At admission, C-reactive protein (CRP), aspartate amino transferase (AST) and estimated glomerular filtration rate (eGFR), according to the CKD-EPI formula predicted death in both sexes. Lymphocytopenia was an independent predictor of death in women only, while thrombocytopenia and elevated plasma glucose concentration were predictors of death in men only. Conclusions In patients with diabetes admitted for COVID-19, female sex was associated with lower incidence of early severe outcomes, but did not influence the overall in-hospital mortality, suggesting that diabetes mitigates the female protection from COVID-19 severity. Sex-associated biological determinants may be useful to optimize COVID-19 prevention and management in women and men.

Abstract

International audience; Automated closed-loop (CL) insulin therapy has come of age. This major technological advance is expected to significantly improve the quality of care for adults, adolescents and children with type 1 diabetes. To improve access to this innovation for both patients and healthcare professionals (HCPs), and to promote adherence to its requirements in terms of safety, regulations, ethics and practice, the French Diabetes Society (SFD) brought together a French Working Group of experts to discuss the current practical consensus. The result is the present statement describing the indications for CL therapy with emphasis on the idea that treatment expectations must be clearly defined in advance. Specifications for expert care centres in charge of initiating the treatment were also proposed. Great importance was also attached to the crucial place of high-quality training for patients and healthcare professionals. Long-term follow-up should collect not only metabolic and clinical results, but also indicators related to psychosocial and human factors. Overall, this national consensus statement aims to promote the introduction of marketed CL devices into standard clinical practice.

Abstract

Adrenocortical carcinoma is a rare malignant tumor of poor prognosis, frequently requiring additional treatments after initial surgery. Due to its adrenolytic action, mitotane has become the first-line medical treatment in patients with aggressive adrenocortical carcinoma. Over the last 2 years, apart from the classical chemotherapy based on etoposide and platinum salts, several studies reported the use of drugs such as temozolomide, tyrosine kinase inhibitors or immunotherapy, with more or less convincing results. The aim of this review is to give further insights in the use of these drugs, and to describe potential therapeutic perspectives based on recent pangenomic studies, for the future management of these still difficult to treat tumors., Le corticosurrénalome malin est une tumeur rare, de mauvais pronostic, nécessitant fréquemment le recours à des traitements médicamenteux après la chirurgie initiale. Depuis de nombreuses années, le mitotane est le traitement de 1re ligne des corticosurrénalomes agressifs, du fait de ses propriétés adrénolytiques. Cependant, ce traitement est souvent insuffisant et associé à une chimiothérapie de type Etoposide/Platine. Au cours des 2 dernières années, plusieurs études ont rapporté l’efficacité plus ou moins probante de nouvelles molécules telles que le temozolomide, les inhibiteurs tyrosine kinase ou l’immunothérapie. L’objectif de cette revue est de préciser les résultats de ces différentes études, et d’apporter quelques données de perspectives basées sur les études pangénomiques, dans l’objectif de mieux appréhender ce que pourrait être la prise en charge de ces tumeurs dans les années à venir.

Abstract

Resume La glycemie post-prandiale est une composante importante d’un controle glycemique optimal. L’implication de la glycemie post-prandiale dans la survenue des complications micro- et macrovasculaires associees au diabete reste discutee. Plusieurs outils therapeutiques ont ete developpes pour limiter l’hyperglycemie post-prandiale, dont les analogues rapides de l’insuline qui ont apporte une contribution decisive. Des analogues ultra-rapides de l’insuline sont en cours de developpement, dans l’objectif d’obtenir un controle optimal des excursions glycemiques post-prandiales, une limitation des hypoglycemies post-prandiales, et une flexibilite des horaires d’injection. Plusieurs techniques ont ete developpees pour ameliorer la pharmacocinetique et la pharmacodynamie des insulines rapides. Des analogues d’action ultra-rapide ont ete developpes principalement pour l’utilisation au cours du diabete de type 1. L’insuline Faster aspart (Fiasp®) est le premier analogue rapide de 2e generation sur le marche francais, mais d’autres analogues ultra-rapides administres par la voie sous-cutanee et des formes orales inhalees de l’insuline d’action ultra-rapides sont en cours de developpement.

Abstract

AIM To assess the safety and efficacy of the short-acting glucagon-like peptide-1 receptor agonist exenatide on a population of patients with type 2 diabetes (T2D) mostly treated with continuous subcutaneous insulin injection (CSII). MATERIALS AND METHODS A phase 2/3, multicentre, randomized, parallel-group, double-blind, placebo-controlled, 6-month trial was conducted. Patients were randomized to receive subcutaneous (SC) injections of exenatide (10 μg BID) or matched placebo. RESULTS A total of 46 patients with T2D and elevated HbA1c were randomized (42% of the planned sample size): exenatide (n = 28) and placebo (n = 18). CSII treatment was used by 75% and 89% of patients of the exenatide and placebo groups, respectively. At 6 months, the change in HbA1c was -0.62% ± 0.94% and 0.08% ± 0.81% in the exenatide and placebo groups, respectively (difference, -0.70%; 95% CI [-1.24%; -0.15%], P = .014); body weight and body mass index decreased in the exenatide group (-2.55 ± 3.25 kg and -1.00 ± 1.31 kg/m2 ) and increased in the placebo group (1.29 ± 2.82 kg and 0.46 ± 1.16 kg/m2 ) (observed difference, -3.85 and -1.45, respectively, both P

Abstract

The strategy for diagnosis of primary aldosteronism (PA) in the hypertensive population includes firstly a screening step, based on the measurement of plasma aldosterone-to-renin ratio (ARR), a test which must have high sensitivity, and secondly a confirmatory step based on the demonstration of excessive aldosterone production independent of the renin-angiotensin-aldosterone system (RAAS) activity. The high proportion of false-positive ARR results and conversely of actual PA without a persistent elevation in baseline plasma aldosterone concentration necessitates the addition of a confirmatory step in the work-up of PA diagnosis. The present review focuses on the description of the different dynamic tests available for demonstrating autonomy of aldosterone secretion, on the performance and limitations of confirmatory tests and on possible strategies for PA diagnosis which may either include or avoid the confirmatory step for PA diagnosis. Large prospective studies comparing different strategies with and without dynamic testing are mandatory to delineate clearly the role and limits of confirmatory tests in the work-up of PA.

Abstract

Background: The DIABEO® system (DS) is a telemedicine solution that combines a mobile app for patients with a web portal for health care providers. DS allows real-time monitoring of basal-bolus insulin therapy as well as therapeutic decision-making, integrating both basal and bolus dose calculation. Real-life studies have shown a very low rate of use of mobile health applications by patients. Therefore, we conducted a large randomized controlled trial study to investigate the efficacy of DS in conditions close to real life (TELESAGE study). Methods: TELESAGE was a multicenter, randomized, open study with three parallel arms: arm 1 (standard care), arm 2 (DIABEO alone), and arm 3 (DIABEO+telemonitoring by trained nurses). The primary outcome assessed the reduction in HbA1c levels after a 12-month follow-up. Results: Six hundred sixty-five patients were included in the study. Participants who used DIABEO once or more times a day (DIABEO users) showed a significant and meaningful reduction of HbA1c versus standard care after a 12-month follow-up: mean difference −0.41% for arm 2—arm 1 (P = 0.001) and −0.51% for arm 3—arm 1 (P ≤ 0.001). DIABEO users included 25.1% of participants in arm 2 and 37.6% in arm 3. In the intention-to-treat population, HbA1c changes and incidence of hypoglycemia were comparable between arms. Conclusions: A clinical and statistically significant reduction in HbA1c levels was found in those patients who used DIABEO at least once a day.

Abstract

AIMS The relative contribution of basal hyperglycaemia (BHG) and postprandial hyperglycaemia (PPHG) in type 2 diabetes patients treated with multiple daily injections (MDI) of insulin is poorly documented. In this study, the BHG and PPHG of patients from the OPT2mise study who were initially treated with MDI were assessed before randomization and again after 6 months of continuous subcutaneous insulin infusion (CSII). MATERIALS AND METHODS Blinded continuous glucose monitoring (CGM) data were collected in 259 MDI patients after completion of an 8-week run-in period. The hyperglycaemic area under the curve (AUC) during the 24-hour basal period (AUC-B) and the postprandial period (AUC-P) were compared with analysis of variance based on contribution to total hyperglycaemia in HbA1c groups (Group 1

Abstract

Bariatric surgery in obese subjects can result in remission of type 2 diabetes (T2D) at a distant time post-surgery. The aim of our observational prospective single-centre study was to examine glycaemic patterns in adult T2D candidates for bariatric surgery using a continuous glucose monitoring (CGM) sensor for 14 days after surgery to search for indicators predictive of T2D remission 1 year later.Patients underwent CGM preoperatively and for 14 days postoperatively. Thereafter, body weight and glycated haemoglobin (HbA1c) levels were monitored at 3, 6 and 12 months after surgery.A total of 31 patients (mean age 47±2 years) were analyzed. After surgery, mean interstitial glucose levels fell rapidly from 157±31mg/dL preoperatively to 109±35mg/dL postoperatively (P0.001), reaching nadir levels from day 3 after surgery. Successful bariatric surgery (loss of excess weight ≥50%) was observed in 28 (90%) patients, and diabetes remission (HbA1c≤6% with no antidiabetic treatment) 1 year after surgery was noted in 21 (68%) patients. CGM for 14 days post-surgery allowed prediction of diabetes remission 1 year after surgery: time spent above range14% and standard deviation (SD) of glucose levels33mg/dL were both strong predictors of T2D remission. Indeed, the association of these two criteria predicted diabetes remission with a 100% positive predictive value, 81% sensitivity and 100% specificity and, when combined with the advanced Diabetes Remission (Ad-DiaRem) score, further increased predictive accuracy.The use of 14-day postoperative CGM recordings together with presurgical clinical scores can help to predict diabetes remission 1 year after bariatric surgery.
