Intrarenal calcifications (nephrocalcinosis) is present in Dent's disease and likely contribute to progression toward renal failure. In order to prevent this complication it is usually proposed to treat affected patients during childhood with high doses of thiazides.

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • to investigate the dose-dependent benefit/risk ratio of low (6.25 mg/day), intermediate (12.5 mg/day) and high (25 mg/day) doses of hydrochlorothiazide [ Time Frame: at the end of the baseline initial and final washout periods (one month each) and at the end of each two-months duration treatment period, ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • clinical events (cramps, symptomatic dehydration, acute weight loss) [ Time Frame: at least two times overall the study, at J15 and at the end of each period. ] [ Designated as safety issue: Yes ]
  • Biological : acute renal failure (estimated GFR), hypokalemia, hyperkalemia, hyponatremia, biological signs of extra cellular dehydration (protides, hematocrit, plasma active renin, plasma aldosterone) [ Time Frame: at least two times overall the study, at J15 and at the end of each period. ] [ Designated as safety issue: Yes ]
