Clinical Trial: Influence of Polymorphisms in the ATP6V1 Gene of the V-ATPase on the Development of Incomplete Distal Renal Tubular Acidosis
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational
Official Title: Comparison of Furosemide/Fludrocortisone With Ammonium Chloride Loading Test in the Diagnosis of Incomplete dRTA in Kidney Stone Formers
Brief Summary:
Purpose
- To compare the performance of the two currently employed urinary acidifications tests in stone formers, the furosemide/fludrocortisone and ammonium chloride loading test.
- To study the impact of polymorphisms in the genes ATP6V1B1, ATP6V0A4 and SLC4A1 on urinary acidification in stone formers.
