Summary
Following a suspected viral infection 4 years previously, a 9-year-old boy developed obesity, hypodipsia, hypernatraemia, hyperosmolality and hyperprolactinaemia. The renal handling of solute and water was normal, but there was a decreased sensitivity of hypothalamic osmoreceptors to both hypernatraemia and water loading. Therapeutic trials with a thiazide diuretic, an aldosterone antagonist, bromocriptine, and longterm sodium restriction with high fluid intake failed to maintain serum sodium and plasma osmolality within the normal range.
