Inappropriate secretion of vasopressin, hypopituitarism and corticosteroid therapy.

Inappropriate vasopressin secretion (SIADH) in burned patients.

To determine if concentration of plasma arginine vasopressin (AVP) is inappropriate for the plasma Na+ concentration in hyponatremic burned patients, we obtained 32 plasma samples from 20 patients with total burn size (TBS) 15 to 80% of body surface on or after postburn day (PBD) 4 in the morning following all-night recumbency. In the 25 samples (17 patients) with hyponatremia, AVP was elevated...

Inappropriate Secretion of TSH Syndrome

The syndrome of inappropriate secretion of TSH was the term originally coined to indicate two forms of central hyperthyroidism, i.e. thyrotropin (TSH)-secreting pituitary adenomas (TSHomas) and resistance to thyroid hormone action (RTH). Both forms are characterized by high levels of free thyroxine (FT4) and free triiodothyronine (FT3) in the presence of measurable TSH concentrations, a biochem...

Reversible hypopituitarism after interferonalfa therapy.

Syndrome of inappropriate antidiuretic hormone secretion.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) results from the aberrant or sustained secretion of the antidiuretic hormone. Classic manifestations include water retention, hyponatremia, and hypo-osmolality of the serum. Treatment is aimed at differentiating SIADH from other causes of hyponatremia, determining the underlying disorder, and alleviating the excessive water re...

Fanconi and inappropriate secretion of antidiuretic hormone syndromes secondary to venlafaxine therapy.

Accessible online at: www.karger.com/journals/nef Venlafaxine, a 2-phenyl-2 (1-hydroxycycloalkyl) ethylamine derivate, is an inhibitor of both serotonin and norepinephrine re-uptake and was termed a ‘dual uptake inhibitor’ [1]. We report on a venlafaxine-treated patient who developed Fanconi’s syndrome (FS) and hyponatremia secondary to inappropriate antidiuretic hormone secretion syndrome (SIA...
