摘要

nephrogenic diabetes insipidus (NDI) is a disease characterized by the production of very large quantities of dilute urine resulting from an inability of the kidney to respond to vaso-pressin (9). In the US, approximately 41,000 people are diagnosed with NDI each year. NDI can result from either congenital or acquired etiologies. Mutations in the type 2 vasopressin receptor (V2R) occur in 90% of families (in which the mutation is known) with congenital NDI and in the aquaporin 2 (AQP2) water channel in the other 10% (9). Congenital NDI has a profound impact on children with the disease who produce up to 20 liters of urine per day and thus must drink 20 liters of water daily to avoid dehydration. Children who suffer multiple episodes of severe dehydration often end up with mental retardation (1). However, mental retardation can be prevented with adequate water intake to prevent dehydration (1). Acquired NDI can result from multiple causes, most commonly by chronic use of lithium, a medication that interferes with cAMP production and signaling, and which is used to treat bipolar disorders (10).
