The effects of amino acid/protein supplementation in patients undergoing hemodialysis: A systematic review and meta-analysis of randomized controlled trials

We evaluated the efficacy of the intervention consisting of amino acid/protein supplementation on muscle mass, muscle strength and physical function in patients on hemodialysis. This systematic review and meta-analysis identified potential studies through a systematic search of 4 electronic database...

description We evaluated the efficacy of the intervention consisting of amino acid/protein supplementation on muscle mass, muscle strength and physical function in patients on hemodialysis. This systematic review and meta-analysis identified potential studies through a systematic search of 4 electronic databases and references from eligible studies from database inception to August 2020. We included only randomized controlled trials reporting the efficacy of amino acid/protein supplementation on muscle mass, muscle strength and physical function in patients on hemodialysis. Of 6529 unique citation records, 4 studies including 243 participants were selected for inclusion in the meta-analysis. Although there were no significant differences in muscle mass and muscle strength between the intervention and control groups, amino acid/protein supplementation was shown to significantly improve physical function (shuttle walk, MD 32.7, 95% CI 21.7 to 43.7, P
