Introduction: Euvolemic hyponatremia (HN) caused by the Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) can predate a diagnosis of malignancy. It is thus essential to accurately diagnose the etiology of HN/SIADH when detected.Methods: Retrospective, descriptive study of all 52 oncological/hematological malignancy patients diagnosed with SIADH in our Department between January 2011 and December 2016. HN was detected via computerized Prima...

Introduction: Hypoaldosteronism (HA), a cause of hypovolemic hyponatremia (HN) with urinary(U) sodium(Na) loss, is often underdiagnosed. We studied 28 patients with an episode of HA-induced moderate/severe hyponatremia.Methods: Retrospective 2012–2015. In all patients, Nadir(N) serum(S) Na <130 mmol/l (corrected for total proteins and glycemia), low internal yugular venous pressure, low ocular pressure. Addison’s Disease ruled (ACTH, cortis...

Introduction: ESE guidelines state a risk for overcorrection of serum sodium levels (SNa) with vaptans. We present the results of our protocol for initiation of tolvaptan(TV) therapy in SIADH.Methods: Retrospective (2011–15). 86 patients with SIADH-induced mild/moderate hyponatremia received TV:7.5 mg day 1, ad-libitum liquids, no other Na-raising therapies. Conventional hospitalization (CH):66/86, day hospital (DH):20/86. Glycemia-corrected SNa det...

Introduction: Hyponatremia is common in the emergency room, albeit frequently overlooked. Our objective was to describe the characteristics of hyponatremia in a cohort of emergency room patients, and evaluate how hyponatremia was studied and followed up.Material and methods: We studied all 211 patients under 70 years-of-age who presented/developed non-translocational hyponatremia (serum sodium (SNa) <135 mmol/l) during the first 48 h of their stay at...

Introduction: Hyponatremia is the most frequent electrolyte disorder found in clinical practice, and has been associated with increased morbimortalty. Hyponatremia is even more common among patients receiving parenteral nutricion(PN), a therapy increasingly in use. However, the morbimortality of hyponatremic patients on PN is unknown.Methods: Retrospective study, selecting all patients receiving PN in a teaching hospital from 01/11/11 to 01/06/12. We eva...
