Other causes of acquired nephrogenic diabetes insipidus include hypokalemia (low blood potassium), post-obstructive polyuria, sickle cell disease or trait, amyloidosis, Sjögren syndrome, renal cystic disease, Bartter syndrome, and various medications (amphotericin B, orlistat, ifosfamide, ofloxacin, cidofovir, vaptans).
Lithium, which is often used to treat bipolar disorder, can cause acquired diabetes insipidus (characterized by the excretion of large volumes of dilute urine) by decreasing the expression of the AQP2 gene. The expression of the AQP2 gene is increased during conditions associated with water retention such as pregnancy and congestive heart failure.
Application of this name to DI arose from the fact that diabetes insipidus does not cause glycosuria (excretion of glucose into the urine). In a large survey conducted amongst patients with central diabetes insipidus, the majority were in favor of changing the disease's name to "vasopressin deficiency" to avoid confusion with diabetes mellitus.

Mutation of the aquaporin 2 vasopressin receptor is a cause of acquired diabetes insipidus. In rats, acquired nephrogenic diabetes insipidus can be caused by impaired regulation of aquaporin-2 due to administration of lithium salts, low potassium concentrations in the blood (hypokalemia) and high calcium concentrations in the blood (hypercalcemia).
The practical importance of high (i.e. close to 1) transference numbers of the charge-shuttling ion (i.e. Li+ in lithium-ion batteries) is related to the fact, that in single-ion devices (such as lithium-ion batteries) electrolytes with the transfer number of the ion near 1, concentration gradients do not develop. A constant electrolyte ...
Central diabetes insipidus, recently renamed arginine vasopressin deficiency (AVP-D), [1] is a form of diabetes insipidus that is due to a lack of vasopressin (ADH) production in the brain. Vasopressin acts to increase the volume of blood (intravascularly), and decrease the volume of urine produced.
There are a variety of known factors that can provoke the inflammatory process within the renal interstitium, including pharmacologic, environmental, infectious and systemic disease contributors. The spectrum of disease presentation can range from an acute process to a chronic condition with progressive tubular cell damage and renal dysfunction.
The most common method of eliminating the liquid junction potential is to place a salt bridge consisting of a saturated solution of potassium chloride (KCl) and ammonium nitrate (NH 4 NO 3) with lithium acetate (CH 3 COOLi) between the two solutions constituting the junction. When such a bridge is used, the ions in the bridge are present in ...
