Chronic kidney disease (CKD) is frequently complicated with hyponatremia, probably because of fluid overload or diuretic usage. Hyponatremia in CKD population is associated with increased mortality, but the effect on renal outcome was unknown. We investigated whether hyponatremia is associated with fluid status and is a prognostic indicator for adverse outcomes in a CKD cohort of 4,766 patients...

BACKGROUND Hyponatremia, the commonest electrolyte imbalance encountered in clinical practice, is associated with adverse outcomes. Despite this, understanding of the association between hyponatremia and stroke mortality outcome is limited. AIMS To investigate the association between admission serum sodium and mortality at various time-points after stroke. METHODS Cases of acute stroke admi...

INTRODUCTION The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most frequent cause of hyponatremia in a hospital setting. However, detailed protocols and algorithms for its management are lacking. Our objective was to develop 2 consensus algorithms for the therapy of hyponatremia due to SIADH in hospitalized patients. MATERIAL AND METHODS A multidisciplinary group ma...

n engl j med 358;25 www.nejm.org june 19, 2008 2738 less than originally planned. Landry and Oliver propose a three-group trial (norepinephrine alone, vasopressin alone, and the two combined), which raises two concerns. First, the sample-size requirements for three-group trials are onerous — much greater than those for two-group trials. Second, treating patients with vasopressin alone would be ...

Thiazide diuretics and selective serotonin reuptake inhibitors (SSRIs) are among the most commonly prescribed medications. Each medication has been associated with the development of severe hyponatremia. The mechanisms involved in the development of hyponatremia differ for each medication. Thiazide diuretics induce hyponatremia by impairment of urinary dilution, renal loss of sodium and potassi...

Hyponatremia is common in both inpatients and outpatients. Medications are often the cause of acute or chronic hyponatremia. Measuring the serum osmolality, urine sodium concentration and urine osmolality will help differentiate among the possible causes. Hyponatremia in the physical states of extracellular fluid (ECF) volume contraction and expansion can be easy to diagnose but often proves di...

Hyponatremia and hypernatremia are common findings in the inpatient and outpatient settings. Sodium disorders are associated with an increased risk of morbidity and mortality. Plasma osmolality plays a critical role in the pathophysiology and treatment of sodium disorders. Hyponatremia and hypernatremia are classified based on volume status (hypovolemia, euvolemia, and hypervolemia). Sodium dis...

Although hyponatremia is a common, usually mild, and relatively asymptomatic disorder of electrolytes, acute severe hyponatremia can cause substantial morbidity and mortality, particularly in patients with concomitant disease. In addition, overly rapid correction of chronic hyponatremia can cause severe neurologic deficits and death, and optimal treatment strategies for such cases are not estab...

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common cause of euvolemic hyponatremia, and many medications have been associated with SIADH. Pregabalin is a drug used for the treatment of neuropathic pain, though common adverse effects include central nervous system disturbance, peripheral edema, and weight gain. However, hyponatremia caused by pregabalin has b...
