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: Some authors consider aldosteronism to be a spectrum, ranging from aldosterone-associated (or low-renin) hypertension (AAH) to primary hyperaldosteronism (PHA) due to bilateral adrenal hyperplasia. Thus, blood pressure (BP) response to mineralocorticoid-receptor blockade (MRB) could be similar.Methods: Retrospective analysis of 60 patients. Screening per Endocrine Society guidelines, positive screening: aldosterone (pg/ml) to direct-renin (...

Introduction: Furosemide can be used in the treatment of SIADH. However, to be effective, renal medulla osmolality (OsmRM) as reflected in urinary osmolality (UOSM) must be high. Sodium is the most important contributor to OsmRM, which increases following the administration of oral salt. We analyze the use of an oral salt load followed by furosemide for the acute/short-term treatment of euvolemic SIADH hyponatremia.Method...

Introduction: Chronic tolvaptan (TV) therapy has been found to be safe and effective in the treatment of chronic SIADH. However, experience with modification of doses over time is limited.Methods: We conducted a retrospective analysis of weekly TV doses (mg) in 41 patients with chronic SIADH treated for a minimum of 3 months, seen a week following discharge and monthly thereafter. Serum sodium (SNa) goal was 137–140 mmol/l, with 50% TV dose reductio...

Introduction: Endocrine Society guideline indications for screening (EGS) of hypertensive patients for hyperaldosteronism are not universally followed in clinical Endocrinology. We present a series of patients with hyperaldosteronism, diagnosed following strict EGS compliance.Methods: Retrospective. Following compliance with EGS in all patients attended in a general Endocrinology outpatient clinic, 70 hypertensive patients were diagnosed with hyperaldost...

Objective: To study the association between the state of iodine nutrition, and the risk of total and cause mortality in a representative sample of the Spanish adult population.Design: Longitudinal observational study to estimate mortality risk according to urinary iodine (UI) concentrations using a sample of 4370 subjects >18 years representative of the Spanish adult population participating in the national study [email protected] (2008–2010). We used ...

Measurement of electrical impedance has been proposed as a way to determine whether a hyponatremic patient is hypovolemic or euvolemic. We compare the usefulness of the physical examination (PE) with bioimpedance for determination of volemia in an outpatient hyponatremia clinic.Method: Descriptive prospective analysis. 11 patients attended at the hyponatremia clinic of a tertiary hospital were evaluated. Impedance was measured by a SECA, indicating the p...

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: Controversy exists regarding type 2 diabetes (T2D) remission rates after bariatric surgery (BS) due to heterogeneity in its definition and patients’ baseline features. We evaluate T2D remission using recent criteria, according to preoperative characteristics and insulin use.Materials and methods: Retrospective study from a cohort of 657 BS performed in a single centre (2006–2011) of which 141 (57.4% women) had T2D. Evaluation of a...

Introduction: Remission of type 2 diabetes (T2D) is a yearned outcome after bariatric surgery (BS). Attention to individuals who do not strictly fulfil remission criteria has been frequently left behind. The aim of this study was to evaluate metabolic control status in patients considered as diabetes ‘non-remitters’.Materials and methods: Retrospective study of 125 patients (59.2% women) with preoperative diagnosis of T2D who underwent BS in a ...
