Background: Patients with adrenal insufficiency suffer from increased morbidity and mortality. Quantitative evidence on the health-care burden of either primary (PAI) or secondary adrenal insufficiency (SAI) among hospitalized medical patients is scarce.Methods: In this observational cohort study, we analysed nationwide acute care hospitalizations from patients with PAI or SAI, respectively, between 2011 and 2015 using prospective administrative data. Pa...

Introduction: The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the predominant cause of hyponatremia but the available treatment options are unsatisfying and often of little efficiency. The selective sodium-glucose co-transporter 2 inhibitor empagliflozin promotes osmotic diuresis due to glucosuria and might be a novel treatment option for SIADH.Material and methods: From September 2016 through December 2018 we randomly assigned 88...

Introduction: Persistent endogenous hyperinsulinemic hypoglycemia in neonates (congenital hyperinsulinism; CHI) is usually due to monogenetic gene variants affecting the insulin secretion. The genetic cause is known in about 50% of patients. We present a new variant within the short-chain L-3-hydroxyacyl-CoA dehydrogenase (HADH) gene causing CHI in two cousins.Methods: The cases of two patients with CHI are presented with a follow-up of >30 ...

Background: The main challenge in the diagnosis of arginine vasopressin deficiency (AVP-deficiency, formerly known as central diabetes insipidus), is its distinction against primary polydipsia. Hypertonic saline stimulated copeptin showed a high diagnostic accuracy of 97% in distinguishing between AVP-deficiency and primary polydipsia (Fenske W, Refardt J, NEJM 2018), but comprises discomfort for patients and requires close sodium monitoring. Arginine stimulated copeptin showe...
