Summary

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease characterized by cystic kidneys and caused by mutations in the polycystic kidney disease and other rare genes. It is associated with salt-sensitive hypertension, which accounts for the majority of morbidity and mortality. About 70% of patients with ADPKD develop hypertension, prior to the onset of kidney function decline. Early onset hypertension, despite its treatment, is independently associated with rapid kidney function decline. The investigators hypothesize that a high-sodium diet in patients with ADPKD is required for the development of vascular stiffness, which precedes hypertension, and that treatment with amiloride reverses this phenomenon.
