Thiazide Diuretics in the Management of Young Children with Central Diabetes Insipidus.

OBJECTIVE: To report our experience in treating infants and toddlers with central diabetes insipidus (DI) with thiazide diuretics.

STUDY DESIGN: A retrospective chart review of all infants and toddlers who were treated with thiazide diuretics for central DI at the Mayo Clinic between 1996 and 2014.

RESULTS: Our cohort consisted of 13 patients. The median age at the start of therapy was 6 months (IQR, 1-14 months). Eight patients were given chlorothiazide at a starting dose of 5-10 mg/kg/day, and 5 patients were treated with hydrochlorothiazide at a starting dose of 1-2 mg/kg/day. The median age at the cessation of thiazide therapy was 18 months (IQR, 11.5-39 months). The main reason for stopping was the lack of continued response, in addition to hypernatremia. There was no hospitalization secondary to hyponatremia and only 1 hospitalization secondary to hypernatremia while receiving thiazide therapy. Calcium was checked periodically in 7 of the 13 patients, and 2 of these 7 patients had persistent hypercalcemia.

CONCLUSION: Thiazide diuretics appear to be safe and effective in treating infants with central DI. They can be continued after the introduction of solid food, and until a lack of response is observed.
