Introduction: Nesidioblastosis is a rare but well recognized disorder of persistent hyperinsulinemic hypoglycemia in infancy, but adult-onset nesidioblastosis associated with hyperinsulinemic hypoglycemia, termed noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS) has also been reported. These patients experience predominantly postprandial hypoglycaemia instead of fasting hypoglycaemia that characterizes insulinoma. Histological findings are islet hypertrophy islet-cel...

Introduction: Maturity-Onset Diabetes of the Young (MODY) is a form of monogenic diabetes caused by mutations in islet-related genes characterized by early-onset and inheritance in an autosomal dominant manner. MODY accounts for 2 to 5% of all cases of diabetes. The clinical presentation is heterogenous. Our aim was to characterize clinical features of patients with MODY in our department.Methods: We retrospectively analysed MODY diabetes cases diagnosed...

IntroductionMaturity Onset Diabetes of the Young (MODY) affects 1–2% of diabetic patients. Subtype 5 (HNF1β mutation) is rare (~1% of all MODY subtypes) and extra-pancreatic manifestations are often present (chronic kidney disease (CKD), liver disease and/or genitourinary malformations).AimTo report and review confirmed MODY 5 cases in an Endocrinology Department.Meth...

Introduction Immune reconstitution therapies (IRT), which include antibody-based cell-depleting therapies targeting CD52+ (alemtuzumab) or CD20+ (rituximab, ocrelizumab) leukocytes, are approved for the treatment of multiple sclerosis. Thyroid autoimmunity is a common adverse effect of alemtuzumab treatment, Graves' disease being the most prevalent manifestation. To date, thyroid autoimmunity events have not been reported with CD20 targeting monoclonal a...

Background: Craniopharyngioma is a benign tumour involving the hypothalamic and pituitary regions that are involved in the production and secretion of oxytocin. Research has shown that dysfunction of the oxytocin system is associated with neurobehavioural and metabolic outcomes, but less is known for its role in patients with craniopharyngioma, largely due to varied study designs and heterogenous methods of assessing the oxytocin system. This systematic review...

Background: In vitro and animal experiments have clearly demonstrated that excessive cortisol, GH and prolactin secretion, as well as dopamine agonists (D2As) and somatostatin analogs (SSAs), often prescribed for their treatment, affect the immune response and the onset/evolution of autoimmune diseases (AIDs) through direct and indirect complex mechanisms. Data from clinical studies are very scanty.Study aim: To assess the 1) distribution of AIDs accordi...

Calcification is physiologically present in bone but also pathophysiologically in the vasculature, favouring cardiovascular diseases. Our aim was to investigate changes in the expression of calcification regulators (CR) during vascular calcification in bone and vasculature. Gene expression levels of OPG, RANKL, OPN, MGP, BSP-II and RUNX2 were determined in bone, aorta and arteria ilica externa tissue samples of 22 transplant donors. Gene expression levels during atheroscleroti...

Background: The multi-tyrosine kinase inhibitor sunitinib is approved for advanced renal cell carcinoma and gastrointestinal stroma tumors. It targets both tumor vessels and malignant cells. Animal experiments have pointed to a direct adrenotoxic effect of the drug.Aims: We hypothesized that sunitinib may inhibit proliferation of adrenocortical cancer (ACC) cells and influence adrenal steroid hormone synthesis.Results: Sunitinib re...

Plasma aldosterone concentration (PAC) to active renin concentration (ARC) ratio (ARR) is an established screening tool for primary aldosteronism. Previously we provided reliable cut-offs measuring PAC by a radioimmunoassay (RIA; Byk&DiaSorin) und ARC by an established immunoluminometric assay (Nichols Institute Diagnostics). Since the latter one is not longer available, we aimed to establish cut-offs for currently available assays.One hundred seven ...

Recent case reports describe hyperinsulinemic hypoglycemia after gastric bypass. The aim of this study was the assessment of insulin resistance and insulin secretion in non-diabetic morbidly obese patients before and six months after bariatric surgery.In 8 non-diabetic morbidly obese patients (OB:6f/2 m, age:42±3a, BMI:47.29±2.2 kg/m2) and 6 controls (CON:4f/2 m, age:43±0a, BMI:23.8±0.5 kg/m2) we performed a freq...
