  • Title: Effect of low-protein diet supplemented with keto acids on progression of chronic kidney disease.
    Author: Garneata L, Mircescu G.
    Journal: J Ren Nutr; 2013 May; 23(3):210-3. PubMed ID: 23611549.
    Abstract:
    Hypoproteic diets are most often discussed for patients with chronic kidney disease (CKD) who do not receive dialysis. A very low-protein diet supplemented with ketoanalogues of essential amino acids (keto-diet) proved effective in ameliorating metabolic disturbances of advanced CKD and delaying the initiation of dialysis without deleterious effects on nutritional status. Several recent studies report that the keto-diet could also slow down the rate of decline in renal function, with better outcomes after the initiation of dialysis. Results of a single-center randomized controlled trial addressing the rate of CKD progression revealed a 57% slower decline in renal function with the keto-diet compared with a conventional low-protein diet (LPD). The keto-diet allowed the safe management of selected patients with stage 4-5 CKD, delaying dialysis for almost 1 year, with a major impact on patient quality of life and health expenditures. Therefore, the keto-diet could be a link in the integrated care model. Careful selection of patients, nutritional monitoring, and dietary counseling are required.
