Abstract
Aim
To evaluate the efficacy and safety of the restricted protein diet supplemented with keto analogues when applied in end-stage renal disease (ESRD).
Methods
The Cochrane Library, PubMed, Embase, CBM and CENTRAL databases were searched and reviewed up to January 2017. Clinical trials were analyzed using RevMan 5.3 software.
Results
Five randomized controlled trials were selected and included in this study according to our inclusion and exclusion criteria. Changes in serum albumin, PTH, triglyceride, cholesterol, calcium, phosphorus, hemoglobin, Kt/v and CRP before and after treatment were analyzed. Meta-analysis results indicated that, compared with normal protein diet, low-protein diet (LPD) supplemented with keto analogues (sLPD) could improve serum albumin (P < 0.00001), hyperparathyroidism (P < 0.00001) and hyperphosphatemia (P = 0.008). No differences in triglyceride, cholesterol, hemoglobin, Kt/v and CRP were observed between different protein intake groups.
Conclusion
Restricted protein diet supplemented with keto analogues (sLPD) may improve nutritional status and prevent hyperparathyroidism in ESRD patients. The current data were mainly obtained from short-term, single-center trails with small sample sizes and limited nutritional status indexes, indicating a need for further study.
