Hyponatremia is the most frequent electrolyte disorder with the syndrome of inappropriate antidiuresis (SIADH) being its predominant cause. Physiological studies in patients with SIADH are difficult to interpret due to usually several comorbidities and polymedication. Therefore, a SIADH model in healthy volunteers would be very helpful to allow insight in this complex disease and to test new therapeutic approaches. The aim of the study was to create a SIADH model with evaluation of subsequent physiological changes...

Taurine content is high (mM) in mammalian brain. By its major role as an osmolyte, taurine contributes to the cell volume control, which is particularly critical in the brain. Taurine participates in osmotic adjustments required to maintain the organization and size of intracellular compartments. It counteracts volume fluctuations in unbalanced transmembrane fluxes of ions and neurotransmitters, preserving the functional synaptic contacts. Taurine has a key role in the long-term adaptation to chronic hyponatremia as well as in other pathologies leading to brain edema...

Hyponatremia is an electrolyte imbalance encountered commonly in the hospital and ambulatory settings. It can be seen in isolation or present as a complication of other medical conditions. It is therefore a challenge to determine the appropriate therapeutic intervention. An understanding of the etiology is key in instituting the right treatment. Clinicians must not be too hasty to correct a random laboratory value without first understanding the physiologic principle. We present such a case of a patient who presented with sodium of 98 mmol/L, the lowest recorded in the current literature, and yet was asymptomatic...

BACKGROUND: Disturbances in water and electrolyte homeostasis are common following transsphenoidal surgery. These disorders are variable and unpredictable, increasing patient risk and complicating postsurgical treatment. Clinically, it is generally accepted that damage to the pituitary is the etiology, but the mechanisms behind the response variability and underlying pathophysiology remains unknown. OBJECTIVE: To test the hypothesis that changing the degree of damage to the pituitary stalk produces a spectrum of water and electrolyte disturbance along which all presentations of postsurgical water and electrolyte disturbances can be identified...

Dysnatremia is a common finding in the intensive care unit (ICU) and may be a predictor for mortality and poor clinical outcomes. Depending on the time of onset (ie, on admission vs later in the ICU stay), the incidence of dysnatremias in critically ill patients ranges from 6.9% to 15%, respectively. The symptoms of sodium derangement and their effect on brain physiology make early recognition and correction paramount in the neurologic ICU. Hyponatremia in brain injured patients can lead to life-threatening conditions such as seizures and may worsen cerebral edema and contribute to alterations in intracranial pressure...

BACKGROUND & OBJECTIVE: Percutaneous endoscopic gastrostomy (PEG) is a procedure to provide enteral nutrition for critically ill patients. It is commonly used in clinical practice; however, the widespread use of PEG is controversial. Our objective was to evaluate the therapeutic effect of nutritional support by PEG in these critically ill patients. METHODS: A total of 64 critically ill patients including 41 males and 23 females (aged 23-84) were identified by the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system during September 2004 to June 2012...

While some electrolyte disturbances are immediately life-threatening and must be emergently treated, others may be delayed without immediate adverse consequences. We discuss a patient with alcoholism and diabetes mellitus type 2 who presented with volume depletion and multiple life-threatening electrolyte and metabolic derangements including severe hyponatremia (serum sodium concentration [SNa] 107 mEq/L), hypophosphatemia ("undetectable," <1.0 mg/dL), and hypokalemia (2.2 mEq/L), moderate diabetic ketoacidosis ([DKA], pH 7...

A reset osmostat as a cause of hyponatremia can be found in a variety of clinical settings, including pulmonary and neurologic diseases, as well as in physiologic circumstances such as pregnancy. This teaching case describes a 72-year-old white man with a long-standing history of self-medicating with desmopressin acetate (DDAVP) who presented with profound hyponatremia. On discontinuation of DDAVP treatment, he was found to have a reset osmostat. The mild hyponatremia persisted on follow-up. We theorize that the reset osmostat may have developed secondary to long-standing DDAVP use...

Body fluid homeostasis requires a complex suite of physiological and behavioral processes. Understanding of the role of the central nervous system (CNS) in integrating these processes has been advanced by research employing immunohistochemical techniques to assess responses to a variety of body fluid challenges. Such techniques have revealed sex/estrogen differences in CNS activation in response to hypotension and hypernatremia. In contrast, it has been difficult to conclusively identify specific CNS areas and neurotransmitter systems that are activated by hyponatremia using these techniques...

PURPOSE: Hyponatremia is a common electrolyte disorder and is associated with mortality. We examined the frequency of appropriate testing in response to an episode of inpatient hyponatremia in a large urban hospital to better inform our educational intervention. We then evaluated the impact of a live CME activity with a focus on CKD- and ESRD-associated hyponatremia physiology, on diagnostic practices of audience hospitalist attendings. METHODS: We performed a retrospective database analysis of all patients admitted to Montefiore Medical Center in 2014 to examine the performance of hospital staff in response to hyponatremia across all CKD stages...

To clarify the association between carboplatin and electrolyte abnormality, a pooled-analysis was performed with the adverse event reports of non-small cell lung cancer patients. A total of 19901 adverse events were retrieved from the FDA Adverse Event Reporting System (FAERS). Pooled reporting odds ratios (RORs) and 95% CIs suggested that carboplatin was significantly associated with hyponatremia (pooled ROR = 1.57, 95% CI 1.18-2.09, P = 1.99×10-3) and hypokalemia (pooled ROR = 2.37, 95% CI 1.80-3.10, P = 5...

This consensus- based S1 Guideline for perioperative infusion therapy in children is focused on safety and efficacy. The objective is to maintain or re-establish the child's normal physiological state (normovolemia, normal tissue perfusion, normal metabolic function, normal acid- base- electrolyte status). Therefore, the perioperative fasting times should be as short as possible to prevent patient discomfort, dehydration, and ketoacidosis. A physiologically composed balanced isotonic electrolyte solution (BS) with 1-2...

BACKGROUND: Hyponatremia is common in patients with subarachnoid hemorrhage, but its effect on outcomes remains contentious. Fluctuation in sodium has been reported to negatively affect perioperative outcomes in general surgical patients, but not specifically in patients with a subarachnoid hemorrhage. The primary aim was to describe the relationship between 1) hyponatremia and 2) sodium fluctuations during intensive care and neurologic outcome at hospital discharge. METHODS: Adults with aneurysmal subarachnoid hemorrhage between January 2012 and September 2013 were retrospectively reviewed...

BACKGROUND: Recent epidemiological studies have implicated chloride, rather than sodium, as the driver of poor survival previously attributed to hyponatremia in heart failure. Accumulating basic science evidence has identified chloride as a critical factor in renal salt sensing. Our goal was to probe the physiology bridging this basic and epidemiological literature. METHODS AND RESULTS: Two heart failure cohorts were included: (1) observational: patients receiving loop diuretics at the Yale Transitional Care Center (N=162) and (2) interventional pilot: stable outpatients receiving ≥80 mg furosemide equivalents were studied before and after 3 days of 115 mmol/d supplemental lysine chloride (N=10)...

Disturbances of water and electrolyte balance are commonly encountered in older patients due to a multitude of physiological changes and preexisting morbidities with hyponatremia being the most common disorder. Even mild chronic hyponatremia can lead to cognitive deficits and gait instability and is associated with an increased rate of falls and fractures. Additionally, experimental and epidemiological data suggest that hyponatremia promotes bone resorption and therefore increases the risk of osteoporosis. Furthermore, osteoporosis and sarcopenia can be stimulated by hypomagnesemia...

Hyponatremia is a common condition encountered in clinical practice. A number of studies have associated low serum sodium levels with increased mortality in various patient populations, such as hospitalized patients and patients with various comorbid conditions; recent studies have shown that individuals with chronic kidney disease also are afflicted by hyponatremia. However, few studies have focused on patients with hemodialysis. Evidence supporting the incidence and prevalence of hyponatremia, clinical characteristics and the association with patient outcomes with hemodialysis is limited...

Hyponatremia, the most common electrolyte disorder in hospitalized patients is associated with increased risk of mortality even when mild and apparently asymptomatic. Likewise morbidity manifested as attention deficits, gait disturbances, falls, fractures, and osteoporosis is more prevalent in hyponatremic subjects. Hyponatremia also generates a significant financial burden. Therefore, it is important to explore approaches that effectively and safely treat hyponatremia. Currently available strategies are physiologically sound and affordable but lack evidence from clinical trials and are limited by variable efficacy, slow response, and/or poor compliance...
