Background: The syndrome of inappropriate antidiuresis (SIAD) can be treated with oral urea. Proteins are metabolized into urea by the liver. We hypothesized that dietary protein could increase free water clearance through urea-induced osmotic diuresis.ObjectivesTo investigate the effect of protein supplementation on plasma sodium levels in chronic SIAD.Methods: This is a monocentric open-label proof-of-concept trial conducted at the University Hospital ...

Background: Today, GLP-1 receptor agonists have great clinical importance in the treatment of type 2 diabetes and obesity. Furthermore, GLP-1 seems to play a significant role in sodium and water homeostasis. Recent findings investigating long-term effects of treatment with GLP-1 receptor agonists showed a reduction of fluid intake irrespective of food consumption. To our knowledge, data regarding physiological mechanisms that could explain these observations are inconclusive. ...

Background: Soluble alpha klotho (sαKL) is high in active acromegaly, normalizes after disease control, and therefore is suggested as a new biomarker for growth hormone (GH) excess. However, little is known about the impact of biological variables other than GH.Methods: Serum sαKL (pg/ml) was measured by ELISA (IBL, Hamburg, Germany). We first evaluated pre-analytical stability, defined a reference interval for sαKL in healthy subjects (A:...

The differential diagnosis between arginine vasopressin deficiency (AVP-D), known as central diabetes insipidus, and primary polydipsia (PP) is challenging. Psychopathologic findings are often used as a hallmark for diagnosing PP; thus. Yet, psychopathologic characteristics are barely assessed in patients with AVP-D, and to date, no data exist comparing AVP-D and PP with regard to these features. Therefore, in this study, we aimed to compare levels of anxiety, depression, alex...

Background: Triple A (Allgrove) syndrome is a rare genetic disorder with autosomal recessive inheritance, caused by mutations in the AAAS gene on chromosome 12q13. It is characterized by the following triad: ACTH-resistant adrenal insufficiency, alacrimia, and achalasia.Case presentation: We present the case of a 19-year-old male who was diagnosed with adrenal insufficiency at the age of five following an addisonian crisis with hypoglycemic coma. At the ...

Background: Steroid synthesis inhibitors, like metyrapone, osilodrostat, and ketoconazole are used as second-line treatment in all types of endogenous Cushing’s syndrome (CS). However, a direct comparison of these three drugs is missing. This study aimed to compare these drugs in the short-term therapy of CS.Design: Retrospective multicenter study involving 16 centers worldwide.Methods: Patients with CS treated with metyrapone...
