Lithium-induced nephrogenic diabetes insipidus.

چکیده
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 diabetes insipidus" and "lithium" from 1990 to the present. A case report describes a patient who had been off lithium for 8 years and who developed hypernatremia after she was transferred to a new long-term facility and the staff attempted to control the patient's polydipsia. The diagnosis and treatment of nephrogenic diabetes insipidus are also discussed. RESULTS This case of persistent nephrogenic diabetes insipidus 8 years after discontinuing lithium is the longest ever reported. Certainly, a number of patients have varying degrees of persistent lithium-related nephrogenic diabetes insipidus. Although pathologic changes are associated with persistent nephrogenic diabetes insipidus, the exact mechanism of the persistent defect is unknown. The mechanism of acute lithium-induced nephrogenic diabetes insipidus while the patient is on lithium is related to changes in intracellular cyclic adenosine monophosphate. CONCLUSIONS Patients currently taking lithium and patients with a remote history of lithium treatment need to be monitored for signs and symptoms of nephrogenic diabetes insipidus. Physicians need to be aware of the potential for nephrogenic diabetes insipidus in these patients and care for them appropriately.

Use of acetazolamide in lithium-induced nephrogenic diabetes insipidus: a case report
Lithium-induced nephrogenic diabetes insipidus (Li-NDI) is a rare and difficult-to-treat condition. A study in mice and two recent papers describe the use of acetazolamide in Li-NDI in 7 patients (a case report and a 6 patient series). We describe the case of a 63-year-old woman with bipolar disorder treated with lithium and no previous history of diabetes insipidus. She was hospitalized due to...

A 45-year-old man, with a 10-year history of manic depression treated with lithium, was admitted with hyperosmolar, nonketotic coma. He gave a five-year history of polyuria and polydipsia, during which time urinalysis had been negative for glucose. After recovery from hyperglycaemia, he remained polyuric despite normal blood glucose concentrations; water deprivation testing indicated nephrogeni...

Acquired nephrogenic diabetes insipidus is most frequently caused by lithium which is used to treat bipolar disorder. The reported incidence of acquired NDI in patients on long term lithium treatment is as high as 55% [2]. Lithium-induced NDI results from inactivation of adenylyl cyclase and thus the phosphorylation of cytoplasmic urinary aquaporin 2 AQP2 by protein kinase A, and consequently A...

We report a patient who developed persistent nephrogenic diabetes insipidus associated with renal tubular acidosis, renal resistance to parathyroid hormone, aminoaciduria and proximal tubule pattern proteinuria in the presence of a reduced glomerular filtration rate (19-24 ml/min). A review of the previous reports of persistent nephrogenic diabetes insipidus revealed that in all patients the gl...
