Caloric Restriction in Autosomal Dominant Polycystic Kidney Disease


About this study

The purpose of this study is to conduct a controlled, unblinded RCT comparing mild CR to a control diet in patients with rapidly progressive ADPKD (class 1C-E by the lrazabal classification), under conditions of standardized hydration and sodium intake, to determine whether it slows the rate of growth of the kidneys (primary endpoint), is well tolerated and safe, lowers levels of IGF-1 in serum and the excretion of inflammation (MCP-1) and fibrosis (TGF-􀁇) biomarkers in urine, improves kidney texture, slows the decline of GFR and the rate of growth of the liver, and improves the quality of life.
