The first two case reports found elevated levels of vasopressin 1. Since, several mechanisms have been proposed for carbamazepine-induced hyponatraemia [ 14 ], and they are probably not mutually exclusive.
How useful will it really turn out to be? In fact, these symptoms strikingly resemble those described in the study by Renneboog et al.
All three patients had chronic hyponatraemia, and severe symptoms such as seizures and coma were absent.
Interestingly, vasopressin levels in normonatraemic and hyponatraemic patients were normal, and did not differ between groups. Case 3 A year-old man presented to the emergency room with symptoms of confusion, unsteadiness and headaches.
When the stimulus for inappropriate vasopressin release fades, hypernatraemia lies in wait, although an intact thirst mechanism and access to water should prevent this.
He had no oedema and his jugular venous pressure was normal. Several pathophysiological scenarios have been discussed for SIADH in these diseases, including a reset osmostat, an effect on baroreceptors or a direct effect of hypercapnia on vasopressin release [ 26,27 ].
Because carbamazepine-induced water retention did not suppress vasopressin, this was additional evidence that resetting of the osmoreceptors must also have occurred.
In Cases 1 and 2, a vaptan would have enabled the patients to benefit from the drugs without hyponatraemia as a side effect. An interesting new example of this dilemma was recently described for imatinib, which was given for acute lymphoblastic leukaemia, but also induced SIADH [ 31 ].
After extensive examinations, we made the final diagnosis of diffuse large B-cell lymphoma. J Pharmacol Exp Ther.CASE STUDY IN HYPONATREMIA 25th Annual Clinical Update in Geriatric Medicine Conference DAVID J.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a common cause of hyponatremia in hospitalized patients and is often described in patients with small-cell carcinoma of the lung.
