Continuous intradialytic amino acid infusion from the start of dialysis is better to avoid catabolism under the high-volume pre-dilution on-line HDF

AbstractIt was reported that amino acid infusion during hemodialysis is useful for improving nutritional status. The optimal administration method of amino acid infusion under the high-volume pre-dilution on-line HDF (HVPO-HDF) was analyzed in this study. Subjects were 10 patients on maintenance dialysis at our clinic. We performed high-volume pre-dilution on-line HDF. We investigated two methods for administration of Neoamiyu® 200-ml total amino acid (TAA) infusion for patients with renal failure: (1) continuous infusion into the dialysis circuit for 4  h from the start of dialysis to its completion (infusion rate 50 ml/h) and (2) continuous infusion started 1 h before completion of dialysis (infusion rate 200 ml/h), and compared pre- and post-dialysis blood concentrations and leakage of TAA, essential amino acids (EAA), and nonessential amino acids (NEAA) between these methods. Pre-dialysis blood concentrations of amino acids showed no difference between both the groups. Post-dialysis blood concentrations of amino acids were higher in all concentrations were significantly higher with continuous infusion starting 1 h before completion o f dialysis. Leakage of amino acids showed no difference between both the groups. The continuous intradialytic amino acid infusion from the start of dialysis is better to avoid catabolism under high-volume pre-dilution on-line HDF.
