DDAVP can also be used; if the patient is able to concentrate urine following administration of DDAVP, then the cause of the diabetes insipidus is neurogenic; if no response occurs to DDAVP administration, then the cause is likely to be nephrogenic.

Although gadolinium agents have proved useful for patients with renal impairment, in patients with severe renal failure requiring dialysis there is a risk of a rare but serious illness, nephrogenic systemic fibrosis, which may be linked to the use of certain gadolinium-containing agents.

Although gadolinium agents are useful for patients with renal impairment, in patients with severe renal failure requiring dialysis, there is a risk of a rare but serious illness called nephrogenic systemic fibrosis ( NSF ) or nephrogenic fibrosing dermopathy, that is linked to the use of MRI contrast agents containing gadolinium.

The use in SIADH actually relies on a side effect; demeclocycline induces nephrogenic diabetes insipidus ( dehydration due to the inability to concentrate urine ) . and, in 1978, a larger study found it to be more effective and better tolerated than lithium carbonate, the only available treatment at the time.

However, diabetes insipidus is either a problem with the production of antidiuretic hormone ( central diabetes insipidus ) or kidney's response to antidiuretic hormone ( nephrogenic diabetes insipidus ), whereas diabetes mellitus causes polyuria via a process called osmotic diuresis, due to the high blood sugar leaking into the urine and taking excess water along with it.

Intravenous contrast media increases diagnostic capability of Enterography MRI . Although it s better tolerated than iodinated contrast media used for CT-scan, the use of Gadolinium-based contrast agent should always be preceded by kidney function assessment, in order to reduce the risk of systemic nephrogenic sclerosis, and prophylactic protocol in case of previous allergic reactions.

Acquired nephrogenic diabetes insipidus can result from impaired regulation of aquaporin-2 due to administration of lithium salts ( as a treatment for bipolar disorder ), low potassium concentrations in the blood ( hypokalemia ), high calcium concentrations in the blood ( hypercalcemia ), or a chronically high intake of water beyond the normal requirements ( e . g ., due to excessive habitual intake of bottled water or coffee ).
