The mechanisms underlying the adverse cardiovascular effects of increased salt intake are incompletely understood, but parallel increases in serum sodium concentration may be of importance. The aim of this retrospective cohort study was to investigate the relationship between serum sodium, hypertension and incident cardiovascular disease (CVD). Routinely collected primary care data from the Royal College of General Practitioners Research and Surveillance Centre were analysed. A total of 231,545 individuals with a measurement of serum sodium concentration at baseline were included...

Changes in serum sodium concentration ([Na⁺]serum ) can permit evaluation of the treatment effect of vasopressin antagonists (vaptans) in patients with worsening heart failure (HF) or cirrhotic ascites; that is, they may act as a treatment stratification biomarker. A two-stage systematic review and meta-analysis were carried out and contextualized by experts in fluid resuscitation and translational pharmacology (registration ID in the International Prospective Register of Systematic Reviews (PROSPERO): CRD42017051440)...

BACKGROUND AND OBJECTIVES: Current therapies for hyponatremia have variable effectiveness and tolerability, and in certain instances, they are very expensive. We examined the effectiveness, safety, and tolerability of urea for the treatment of inpatient hyponatremia. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We identified all patients hospitalized at the University of Pittsburgh Medical Center between July 2016 and August 2017 with hyponatremia (plasma sodium <135 mEq/L) who received urea, including a subgroup of patients who received urea as the sole drug therapy for hyponatremia (urea-only treated)...

It is important to grasp a patient's daily sodium intake in the management of chronic kidney disease, as sodium intake is widely recommended at 6 g/day or less. There are multiple equations widely known for estimating the daily sodium excretion from a spot urine sample, but these are aimed at healthy people. There are few reports that validate equations in patients with chronic kidney disease. The purpose of this study is to evaluate whether the amount of measured daily sodium excretion from a sample collected for 24-h urine (24HU) is equal to that of using an equation from a spot urine sample (SU) in patients with chronic kidney disease...

Marion Vallet, Acil Jaafar, Pierre-Yves Charles, Ivan Tack
INTRODUCTION: Estimation of volemic status can be useful in the diagnosis of some hydro-electrolytic disorders such as hyponatremia and dyskalemia. As a matter of fact, clinical examination and classical biological parameters are not discriminant enough. The aim of this study was to determine the biological parameters that are better correlated to volemic status. METHOD: Volemic status was established using extracellular fluid volume, measured by apparent distribution of inuline, in non-edematous patients and without cardiac or hepatic insufficiency...

What is the topic of this review? Sensing the amount of ingested sodium is one mechanism by which sodium balance is regulated. This review describes the role of gastrin in the cross-talk between the stomach and the kidney following the ingestion of sodium. What advances does it highlight? Neural mechanisms and several gut hormones, including cholecystokinin and uroguanylin, have been suggested to mediate the natriuresis after an oral sodium load. It is proposed that gastrin produced by G-cells via its receptor, cholecystokinin B receptor, interacts with renal D1 -like dopamine receptors to increase renal sodium excretion...

PURPOSE OF REVIEW: Textbook theory holds that extracellular fluids readily equilibrate, electrolyte concentrations in the extracellular fluid compartments are constant, and the kidney is solely responsible for controlling the body sodium content. RECENT FINDINGS: Investigation of salt and water balance traditionally relies on short-term studies of bodily responses to extremes in salt intake. Ultra-long-term sodium balance studies instead studied the kidney's response to constant salt intake...

Hiroshi Ochiai, Eita Uenishi
A 79-year-old woman without any cerebral hernia symptoms was hospitalized with hyponatremia. After syndrome of inappropriate antidiuretic hormone induced by drugs was diagnosed and water restriction implemented, the patient became comatose during overcorrection caused by the generation of a large volume of electrolyte-free urine. Once the serum sodium concentration was immediately relowered by the administration of desmopressin and 5% glucose solution, the patient's level of consciousness improved dramatically without osmotic demyelination syndrome (ODS) developing...

BACKGROUND: The indirect water-deprivation test is the current reference standard for the diagnosis of diabetes insipidus. However, it is technically cumbersome to administer, and the results are often inaccurate. The current study compared the indirect water-deprivation test with direct detection of plasma copeptin, a precursor-derived surrogate of arginine vasopressin. METHODS: From 2013 to 2017, we recruited 156 patients with hypotonic polyuria at 11 medical centers to undergo both water-deprivation and hypertonic saline infusion tests...

REVIEW
Akira Kuriyama, Seigo Urushidani
Diuretic therapy is important in critically ill patients because fluid overload impairs organ function and increases mortality. Compared to intermittent administration, continuous infusion of loop diuretics is theoretically superior in terms of diuresis and electrolyte balance. However, the available evidence is susceptible to carryover diuretic effects and resistance in earlier crossover trials. Consequently, we conducted a systematic review and meta-analysis of parallel-group randomized controlled trials to compare these two strategies in adults with acute decompensated heart failure...

Sodium is the most important osmotically effective cation in the extracellular space and very important for the water balance of the organism. Disturbances in the sodium homeostasis are therefore usually closely associated with disturbances in the water balance. The most important organs involved in the regulation of the sodium homeostasis are the kidneys and the brain. Disturbances of sodium homeostasis are common electrolyte disturbances, which can cause serious complications, as well as their improper therapy...

Proximal salt reabsorption in the hypertrophied tubules in the early phase of chronic renal failure (CRF) would be diminished according to the inhibited expression of proximal salt-transporting molecules, which may be facilitated by the inhibition of Na-K-ATPase expression. Results from animal models suggest that patients with early-phase CRF would easily develop hyponatremia and, in contrast, patients showing developed CRF would be more likely to show dehydration or hypernatremia. Several large-scale studies of individuals with chronic kidney disease (CKD) revealed that hyponatremia is much more common than hypernatremia in patients with earlier stages of CKD...

BACKGROUND: Chronic (present > 48 hours) non-hypovolaemic hyponatraemia occurs frequently, can be caused by various conditions, and is associated with shorter survival and longer hospital stays. Many treatments, such as fluid restriction or vasopressin receptor antagonists can be used to improve the hyponatraemia, but whether that translates into improved patient-important outcomes is less certain. OBJECTIVES: This review aimed to 1) look at the benefits and harms of interventions for chronic non-hypovolaemic hypotonic hyponatraemia when compared with placebo, no treatment or head-to-head; and 2) determine if benefits and harms vary in absolute or relative terms dependent on the specific compound within a drug class, on the dosage used, or the underlying disorder causing the hyponatraemia...

OBJECTIVES: Hyponatremia is associated with poor outcomes in cirrhosis independent of MELD. While intravenous albumin has been used in small series, its role in hyponatremia is unclear. The aim of this study is to determine the effect of albumin therapy on hyponatremia. METHODS: Hospitalized cirrhotic patients included in the NACSELD (North American Consortium for End-Stage Liver Disease) cohort with hyponatremia (Na <130mmol/L) were divided into those receiving intravenous albumin or not...

BACKGROUND: Hyponatremia is the most common electrolyte disorder among hospitalized patients. Controversies still exist over the relationship between hyponatremia and outcomes of hospitalized patients. METHODS: To analyze the association of low serum sodium levels at hospital admission with in-hospital mortality and patient disposition and to compare the distribution of the risk of death associated with hyponatremia across the lifespan of hospitalized patients, we conducted an observational study of 2...
