Cerebral salt wasting syndrome (CSWS) also presents with hyponatremia, there are signs of dehydration for which reason the management is diametrically opposed to SIADH. Importantly CSWS can be associated with subarachnoid hemorrhage (SAH) which may require fluid supplementation rather than restriction to prevent brain damage.
Normal volume hyponatremia, wherein the increase in ADH is secondary to either physiologic but excessive ADH release (as occurs with nausea or severe pain) or inappropriate and non-physiologic secretion of ADH, that is, syndrome of inappropriate antidiuretic hormone hypersecretion (SIADH).
The medical word for low sodium levels is hyponatremia. Although it's a fairly common condition, with up to 2% of people having some degree of it, the majority of these patients have only mildly ...
The term "cerebral hyponatremia" was suggested in the work of Epstein, et al. 1961. Inappropriate release of endogenous vasopressin is probably responsible for hyponatremia in tuberculous meningitis. Inability to excrete water normally is also a feature of the salt wasting of certain hyponatremic patients with pulmonary tuberculosis.
Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used. [2] When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.
In other words, the unloading of arterial baroreceptors when the arterial blood volume is low stimulates vasopressin secretion despite the presence of hypoosmolality (hyponatremia). [29] The AVP that is measured in peripheral blood is almost all derived from secretion from the posterior pituitary gland (except in cases of AVP-secreting tumours).
SIADH causes HYPOnatremia not HYPERnatremia, since the nephrons don't allow the loss of as much water as they should. They still lose the sodium, so since the sodium level drops but the water level doesn't drop as fast, HYPOnatremia delvelops. As far as I could see, the article does call, it HYPOnatremia, which is correct.
