Background: Differential diagnosis of hyponatremia is challenging, particularly for thiazide associated hyponatremia (TAH), as patients might have either volume depletion in need for fluid substitution or syndrome of inappropriate antidiuresis (SIAD)-like presentation requiring fluid restriction. Urine indices are of little utility, because they are influenced by thiazide therapy. Apparent strong ion difference (aSID) describes the relation between sodium, potassium and chlori...

Introduction: The syndrome of inappropriate antidiuresis (SIAD) is the most common cause of euvolemic hyponatremia. Besides fluid restriction, increasing free water clearance is an effective treatment approach that can be achieved through osmotic diuresis by administering oral urea. Dietary proteins are metabolized into soluble excretable urea by the liver. We hypothesized that dietary protein could increase free water clearance through urea-induced osmotic diuresis and theref...

Introduction: Hyponatremia is the most common electrolyte disorder encountered in clinical practice and is associated with increased mortality and morbidity, including an increased risk for osteoporosis and fragility fractures. Preclinical studies suggest osteoclast upregulation whereas a clinical study showed improved osteoblast fuction after hyponatremia normalization in hospitalized patients with SIAD.Methods: This is a secondary analysis of a double-...

Introduction: Alcohol use disorder AUD causes high socio-economic costs and has a detrimental impact on health globally, being considered a key risk factor for non-communicable diseases. In Switzerland, four substances are currently approved for treatment of AUD, with varying effects. Taking into consideration the complex nature of the disease and the heterogeneity of affect patients, it becomes evident that there is need for new treatment targets. A body of preclinical studie...

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: Hyponatremia is highly prevalent in patients with COVID-19. One of the most common causes of hyponatremia in these patients is the syndrome of inadequate antidiuresis (SIAD). Interleukin 6 (IL-6) is a key mediator of inflammation in COVID-19. We hypothesized that hyponatremia in COVID-19 is due to IL-6 mediated non-osmotic arginine vasopressin (AVP) secretion, and that the inverse association between IL-6 and plasma sodium concentration is stronger in COVID-19 comp...
