Title: Effect of Very Low Protein Diet Supplemented With Ketoanalogues of the Essential Amino Acids on the Progression of Chronic Kidney Disease
Brief Summary: This is a prospective single center randomized controlled trial with a total duration of 18 months aiming to evaluate the effectiveness and the safety of a very low protein diet supplemented with ketoanalogues of essential aminoacids in reducing the progression of chronic kidney disease (CKD) in patients with advanced CKD.
