STUDY DESIGN AND METHODS: We conducted electronic searches in PubMed, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov from January 1960 to May 2018 to identify randomized controlled clinical trials that explored the effects of restricted protein diet including vegetarian and mixed type of protein with KAs on kidney endpoints including the changes in estimated glomerular filtration rate (eGFR) and proteinuria, nutritional status, and CKD-mineral bone disorder. RESULTS: Seventeen RCTs with 1,459 participants were included in our meta-analysis. Restricted protein diet with KAs significantly preserved eGFR and reduced proteinuria, serum phosphate, parathyroid hormone (PTH) level, systolic blood pressure, diastolic blood pressure, and serum cholesterol. By subgroup analysis, very low protein diet (VLPD) with KAs was plausibly superior to LPD with KAs in slowing the decline in eGFR. Only VLPD with KAs significantly improved serum PTH, systolic blood pressure, and diastolic blood pressure while both regimens significantly decreased serum phosphate. Only LPD with KAs significantly raised serum albumin and serum calcium. CONCLUSION: Restricted protein diet supplemented with KAs could effectively improve kidney endpoints including preserving eGFR and diminishing proteinuria, blood pressure levels, and CKD-mineral bone disorder parameters without causing malnutrition. VLPD with KAs appears to provide more effectiveness in slowing the decline in eGFR, lowering blood pressure, reducing serum PTH, and less increasing serum calcium level.
