Effects of Low Protein Diet Supplemented Keto-/Amino Acid in Preventing the Progression of Chronic Kidney Disease (CKD)- ELPD Study

Overview

The purpose of this study is to determine whether low protein diet and very low protein diet supplemented keto-/amino acid is effective in preventing the progression of chronic kidney disease (CKD , stage 3b and 4).

Dietary protein restriction represents a basic therapeutic approach in chronic kidney disease(CKD), by reducing the accumulation of nitrogen catabolic substances, and by delaying the progress of CKD and proteinuria, but the effects of the different degree's protein diet on the renal progression remain to be determined. The aim of this study is to evaluate the efficacy of low protein diet and α-keto acid tablet in retard the progress of CKD. This is a randomized, open-label, prospective study, 120 patients who meet inclusion and exclusion criteria will be randomized into three groups at the ratio of 1:1:1. Group I patients will receive low protein diet(0.6g/kg BW), group II will receive low protein diet supplemented with α-keto acid, while group III will take very low protein diet(0.3g/kg BW) supplemented with α-keto acid. The changes of glomerular filtration rate in CKD will be evaluated after 1 year treatment.
