Using the laboratory database of a large teaching hospital, we have explored the relationship between serum sodium and serum cortisol, and have estimated the frequency of hypoadrenalism in severely hyponatraemic patients.

Increased dietary sodium intake increases urinary free cortisol excretion and may increase the risk for false-positive results. Variations in dietary sodium intake may influence the interpretations of cortisol measurements performed to evaluate for hypercortisolism. Keywords: sodium, dietary sodium, cortisol, urinary free cortisol. INTRODUCTION

2023年9月8日 · The electrolyte disturbances in primary adrenal insufficiency are due to diminished secretion of cortisol and aldosterone (see "Causes of primary adrenal insufficiency (Addison disease)"). A major function of aldosterone is to increase urinary potassium secretion.

Cortisol deficiency also leads to an increase in cortisol-releasing hormone (CRH) production from the hypothalamus, which is an ADH secretagogue. Cortisol has a negative feedback on CRH and ACTH [ 11 ], which is lacking in patients with adrenal insufficiency.

In adults, high Na intake is associated with high levels of urinary cortisol. We aimed to determine the association between urinary Na and K and urinary cortisol in a cross-sectional sample of Australian schoolchildren and their mothers.

2017年8月1日 · Using the laboratory database of a large teaching hospital, we have explored the relationship between serum sodium and serum cortisol, and have estimated the frequency of hypoadrenalism in severely hyponatraemic patients.

2017年7月19日 · Relationship of Serum Cortisol and Serum Sodium Analyzed Hyponatremia is the most common electrolyte disorder encountered by the clinical biochemist, and is associated with a significant mortality and hypernatremia is also a …

2000年11月1日 · They are also consistent with the notion that cortisol at a lower dose produces sodium retention through a type I receptor–mediated mechanism blocked by spironolactone, but at higher cortisol concentrations there is downregulation of type I receptors, and sodium retention reflects other mechanisms.
