Physiopathology and diagnosis of nephrogenic diabetes insipidus

Physiopathology and diagnosis of nephrogenic diabetes insipidus.

Nephrogenic diabetes insipidus (NDI) is caused by an improper response of the kidney to the antidiuretic hormone arginine vasopressin (AVP), leading to a decreased ability to concentrate urine which results in polyuria and polydipsia. The clinical diagnosis of NDI relies on demonstration of subnormal ability to concentrate urine despite the presence of AVP. NDI is most commonly acquired, second...

[nephrogenic Diabetes Insipidus].

In spite of its rare incidence, the inherited renal tubular disorder nephrogenic diabetes insipidus (NDI) has in the past 10 years attracted the attention of a varied group of medical doctors and basic scientists. With the identification of the two genes involved in NDI, namely the vasopressin type-2 receptor (V2R) and the aquaporin-2 water channel (AQP2) genes, the identification of a large nu...

Lithium-induced nephrogenic diabetes insipidus.

BACKGROUND Lithium can cause nephrogenic diabetes insipidus in up to 20 to 40 percent of patients currently taking the medication, and a subset of these patients will have a persistent concentrating defect long after lithium is discontinued. They are at risk for serious hypernatremia when fluid intake is restricted for any reason. METHODS MEDLINE as used to search the key words "nephrogenic d...
