Chronic hyponatremia in a patient with renal salt wasting and without cerebral disease: relationship between RSW, risk of fractures and cognitive imp…

2018

Renal salt wasting syndrome (RSW) is defined as a renal loss of sodium leading to hyponatremia and a decrease in extracellular fluid volume (ECV). Differentiation of this disorder from the syndrome of inappropriate antidiuretic hormone secretion (SIADH), a common cause of hyponatremia, can be difficult because both can present with hyponatremia and concentrated urine with natriuresis. Our clinical case about a 78-year-old woman with a recent fracture of the right femur not only confirms that this syndrome can occur in patients without intracranial pathologies (CT documented), but depicts how the hyponatremia caused by RSW can show a chronic, oscillating course. This is an interesting point …

Physiopathologica, epidemiologica, clinical and therapeutic aspects of exercise-associated hyponatriemia

2014

Exercise-associated hyponatremia (EAH) is dilutional hyponatremia, a variant of inappropriate antidiuretic hormone secretion (SIADH), characterized by a plasma concentration of sodium lower than 135 mEq/L. The prevalence of EAH is common in endurance (6 hours in duration), in which both athletes and medical providers need to be aware of risk factors, symptom presentation, and management. The development of EAH is a combination of excessive water intake, inadequate suppression of the secretion of the antidiuretic hormone (ADH) (due to non osmotic stimuli), long race duration, and very high or very low ambient temperatures. Additional risk factors include female gender, slower race times, and…

L’IPONATRIEMIA NELL’ANZIANO: UNA PROBLEMATICA SEMPRE ATTUALE

2015

Le alterazioni della concentrazione plasmatica del sodio rappresentano una delle disionie di più frequente riscontro nei pazienti ricoverati e che l’incidenza e la prevalenza aumentano con l’età. Molteplici fattori correlati all’invecchiamento giocano un ruolo in tal senso; ad esempio, variazioni anatomiche e funzionali, modificazioni della composizione corporea, alterazioni dei meccanismi fisiologici che regolano il metabolismo e l’omeostasi del sodio e dell’acqua. L’aumento dell’incidenza di tali disturbi nella popolazione anziana rappresenta un chiaro esempio di come l’invecchiamento è in grado di compromettere le capacità di compenso, di adattamento e l’omeostasi dell’organismo. Alterat…

Iponatriemia ed esercizio fisico

2012

L’iponatriemia associata ad esercizio fisico (EAH) è una evenienza degli sport di resistenza che può esitare in gravi manifestazioni cliniche quali l’edema cerebrale o l’insufficienza respiratoria. L’EAH è una iponatriemia diluizionale, variante della secrezione inappropriata di ADH (SIADH), caratterizzata da una concentrazione plasmatica di sodio inferiore a 135 mEq/l. Il sesso femminile e la durata delle competizioni si associano a più elevato rischio di iponatremia. L’incidenza di iponatriemia, infatti, aumenta con la durata dell’attività in special modo dopo 4-8 ore dall’inizio della gara. Le donne sembrano presentare un rischio maggiore rispetto agli uomini. I meccanismi fisiopatologic…

Exercise-associated hyponatremia (EAH) is dilutional hyponatremia, a variant of inappropriate antidiuretic hormone secretion (SIADH), characterized by a plasma concentration of sodium lower than 135 mEq/L. The prevalence of EAH is common in endurance (<6 hours) and ultra-endurance events (>6 hours in duration), in which both athletes and medical providers need to be aware of risk factors, symptom presentation, and management. The development of EAH is a combination of excessive water intake, inadequate suppression of the secretion of the antidiuretic hormone (ADH) (due to non osmotic stimuli), long race duration, and very high or very low ambient temperatures.
