Background: Pathogenic variants in -encoding PLIN1 (perilipin-1) are responsible for an autosomal dominant form of familial partial lipodystrophy (FPL) associated with severe insulin resistance, hepatic steatosis, and important hypertriglyceridemia. This study aims to decipher the mechanisms of hypertriglyceridemia associated with -related FPL.

Methods: We performed an in vivo lipoprotein kinetic study in 6 affected patients compared with 13 healthy controls and 8 patients with type 2 diabetes.

Objective: Pituitary stalk interruption syndrome (PSIS) is a rare cause of congenital hypopituitarism. Limited data exist on the gonadotropic status and fertility of adult women with PSIS. Our study aims to describe pubertal development and the evolution of gonadotropic function and fertility in adult women with PSIS.

Pituitary deficiency, or hypopituitarism, is a rare chronic disease. It is defined by insufficient synthesis of one or more pituitary hormones (growth hormone, TSH, ACTH, LH-FSH, prolactin), whether or not associated with arginine vasopressin deficiency (formerly known as diabetes insipidus). In adult patients, it is usually acquired (notably during childhood), but can also be congenital, due to abnormal pituitary development.

  • Most insulin catheters are changed every 3 days, and this study evaluates how these changes affect glucose control in type 1 diabetes patients using two different insulin delivery methods: open-loop (OL) and automated insulin delivery (AID).
  • Researchers analyzed data from 134 patients who used the Tandem t:slim x2 insulin pump and Dexcom G6 sensor over a 3-month period, focusing on the percentage of time their glucose levels were above 180 mg/dL (%TAR180) on the day of the catheter change and the following two days.
  • Results indicated that there was a significant increase in time spent in hyperglycemia on the day of catheter change for both OL and AID modes,

Multiple endocrine neoplasia (MEN) is a group of syndromes with a genetic predisposition to the appearance of endocrine tumors, and shows autosomal dominant transmission. The advent of molecular genetics has led to improvements in the management of MEN in terms of diagnosis, prognosis and therapy. The genetics of MEN is the subject of regular updates, which will be presented throughout this paper.

  • Lipohypertrophy, a common issue for insulin-dependent diabetics, may negatively impact diabetes management, but its effects on glycemic control and insulin dosing were not well understood prior to this study.
  • Researchers conducted a systematic review and meta-analysis on studies published from 1990 to January 2023, ultimately analyzing data from 37 studies involving over 5,500 records.
  • The results revealed that patients with lipohypertrophy had significantly worse glycemic control, experiencing more hypoglycemia, higher HbA1c levels, and requiring more daily insulin compared to those without the condition.

  • The study aimed to assess how practical, safe, and effective automated insulin delivery (AID) is for people with type 2 diabetes who need help managing multiple daily insulin injections (MDI) at home, supported by home health care (HHC) services.
  • A total of 30 adults were randomly assigned to either AID or their usual therapy for 12 weeks, measuring their time within the target glucose range and other health metrics.
  • Results showed that AID significantly improved the time in the target glucose range and HbA1c levels, with high satisfaction among patients and caregivers, indicating AID is a safe and effective option for managing diabetes.

  • A study evaluated the safety and effectiveness of automated insulin delivery (AID) in adults with type 1 diabetes (T1D) who are at a high risk of hypoglycemia, enrolling 72 participants who had a history of severe hypoglycemic events.
  • Participants were randomly assigned to use either AID technology or traditional continuous glucose monitoring (CGM) and insulin pump therapy for 12 weeks, measuring changes in time below range (TBR) and other glucose metrics.
  • Results showed that AID significantly reduced TBR by 3.7% and increased time in target range (TIR) by 8.6%, leading to the conclusion that AID is highly recommended for adults with T1D at

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.

The use of continuous subcutaneous insulin infusion (CSII) via insulin pumps is today considered standard of care for type 1 diabetes (T1D). Closed-loop systems combining continuous glucose monitoring with automated algorithm-driven insulin delivery have been shown to be safe and efficacious in randomized controlled trials and real-life studies in both paediatric and adult participants with T1D. Implementation of hybrid closed-loop (HCL) systems has shown incremental effectiveness, with further reduction of hypoglycaemia and hyperglycaemia.

Congenital adrenal hyperplasia (CAH) is a genetic disease caused by an enzyme deficiency interrupting adrenal steroidogenesis. It most frequently involves 21-hydroxylase, which induces adrenal insufficiency with hyperandrogenism. Restoring hormonal balance is difficult with glucocorticoids, which are the gold-standard treatment.

  • * Results showed a significant reduction in median 24-hour urinary free cortisol levels, achieving normal levels in many patients within two weeks, regardless of their treatment history.
  • * While osilodrostat improved major clinical symptoms and comorbidities, like hypertension and hyperglycemia, it also led to adrenal insufficiency in 8 out of 33 patients, indicating potential safety concerns.

Introduction: The use of predictive low-glucose suspend (PLGS) sensor-augmented pumps has been shown to lead to a significant reduction in hypoglycemic episodes in patients with type 1 diabetes (T1D), but their effects on hyperglycemia exposure are heterogeneous. The aim of this study was to determine the settings of the Medtronic 640G system to obtain the optimal balance between occurrence of both hypoglycemia and hyperglycemia.

Methods: The hypo- and hyperglycemia area under the curve (AUC), as well as system settings [hypoglycemic threshold, mean insulin total daily dose (TDD), mean basal insulin percentage, and mean daily duration of PLGS] were collected between 2 and 12 times during 1 year in patients from four university hospital centers.
