Introduction: Increased plasma levels of interleukin-6 (IL-6) in response to acute hypoglycemia have been well documented. Counter-regulatory hormones are likely to play a role in this inflammatory response.Objective: To study the interaction between IL-6 and counter-regulatory hormones during hypoglycemic stress.Methods: We conducted an exploratory single center study involving 23 patients (mean age = 34.15 ± 8.87 years, ...

Introduction: The differential diagnosis between arginine vasopressin deficiency (AVP-D), formally known as central diabetes insipidus, and primary polydipsia (PP) is challenging. In clinical routine, psychopathologic findings are often used as a hallmark for diagnosing PP; thus, it is often referred to as psychogenic polydipsia. 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 th...

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...

The islet-enriched transcription factor MAFA regulates the expression of genes critical to beta cell function and insulin secretion. We previously described anovel MAFA mutation (c.191C > T, p.S64F) causing familial insulinomatosis and diabetes mellitus, with male carriers more often developing diabetes and females more prone to insulinomatosis. The exact molecular mechanisms underlying these phenotypes are unclear. In this study, we assessed glucose metabolism an...

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...
