[Progression of renal function in patients with chronic kidney disease on a low-protein diet supplemented with aminoacids and ketoanalogues].

Introduction: chronic kidney disease (CKD) is a public health problem. Low-protein diets supplemented with ketoacids and essential aminoacids have proved effective at different CKD stages.

Aim: to assess the progression of renal failure in adult patients with CKD stages 3b and 4 receiving a protein-controlled diet supplemented with aminoacids and ketoanalogues.
