We report a familial case of the nephrogenic syndrome of inappropriate antidiuresis (NSIAD), including 30-year followup data on two patients. The proband and one maternal uncle presented in their infancy with severe recurrent hyponatremia, and clinical pictures consistent with the syndrome of inappropriate antidiuretic hormone (SIADH) in the absence of an elevated ADH level. They were both conf...

We describe the case of a patient with multiple paraneoplastic syndromes, six in total, associated with a non-small-cell cancer of the lung. In this single patient we found hypertrophic pulmonary osteoarthropathy, hyperkeratosis of palms and soles, erythema annulare centrifugum, syndrome of inappropriate secretion of antidiuretic hormone (SIADH), and ectopic andrenocorticotrophic hormone (ACTH)...

Bupropion is widely used for the treatment of depressive disorder and smoking cessation. Hyponatremia, including a syndrome of inappropriate secretion of antidiuretic hormone (SIADH), is not rare complication of treatment with antipsychotic drugs. We report a 60-year-old man who experienced severe hyponatremia after a treatment with bupropion for depressive disorder for the first time in the Ko...

Treatment with some drugs may lead to the syndrome of inappropriate antidiuretic hormone secretion (SIADH), the presence of which is more likely in some populations, including people who are elderly or who take diuretics. Resulting drug-induced hyponatremia is often mild and usually resolves following water restriction and withdrawal of the drug. In some patients, however, it may be a potential...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used analgesics. Although rare, clinicians need to keep in mind that their use may precipitate hyponatremia and syndrome of inappropriate antidiuretic hormone (SIADH), especially in high-risk patients with multiple comorbidities. In the kidneys, prostaglandins attenuate the water retention effect of antidiuretic hormone. NSAIDs cause a ...

Relatively frequent pituitary hormone deficiencies are observed after traumatic brain injury (TBI) and subarachnoid hemorrhage (SAH) and according to the published studies the neuroendocrine consequenses of traumatic brain injury are underdiagnosed. In a cohort of 59 patients (49 males, mean age 68.3 years, 36-88 years) after evacuation of subdural hematoma (SDH) were evaluated hypothalamo-pitu...

Excessive secretion of vasopressin in the course of Syndrome of Inappropriate Antidiuretic Hormone Secretion is a common cause of hyponatremia in cancer patients. Clinical symptoms depend on the cause, rate of change of sodium level and their absolute values. Treatment options include fluid restrictions, intravenous administration of hypertonic sodium chloride solutions, loop diuretics and vapt...

A new method was developed for the estimation of arginine vasopressin (AVP) in plasma and urine. Samples were extracted by a microcolumn of resin and assayed radioimmunologically using a highly sensitive antiserum to AVP. Ion-exchange resin, CG-50, H+ form, packed in a small column (diameter 4 mm, height 6 mm), was proved effective to remove the interfering substances and to concentrate the AVP...
