Oral Intradialytic Amino Acid Supplementation to Vitalize End-stage Kidney Disease Patients on Hemodialysis

Overview

The study will test and compare the efficacy of a single essential amino acid valine with a combination of essential amino acids (EAA) supplement on fatigue, frailty, and cognitive function in end-stage kidney disease (ESKD) patients undergoing hemodialysis (HD) treatment.

Detailed Description

This single center outpatient study will test and compare the efficacy of a single essential amino acid, valine with a combination of essential amino acids (EAA) supplementation on fatigue, fragility and cognitive function in end-stage kidney disease (ESKD) patients aged 18-64 years undergoing hemodialysis (HD) treatment at least three times a week.

Interventions

  • Drug: Valine
    • A medical food intended for use under medical supervision
  • Drug: EEA
    • A medical food intended for use under medical supervision

Arms, Groups and Cohorts

  • Experimental: Treatment group Valine then EEA
    • Valine will be administered as two 4 gm packets administered on dialysis treatment day followed by a washout period and then EEA
  • Experimental: Treatment group EEA then Valine
    • EAA will be administered as one 12.5 gm packet administered on dialysis treatment day followed by a washout and then Valine

Clinical Trial Outcome Measures

Primary Measures

  • Brief Fatigue Inventory (BFI) score
    • Time Frame: Baseline to 17 weeks
    • Changes in global fatigue score measured with the 9-item Brief Fatigue Inventory (BFI). The first 3 questions assess fatigue severity, and the remaining 6 questions measure the impact of fatigue on activity, mood, walking, work, relationships, and enjoyment of life. Respondents rate each item on a 0-10 numeric scale, with 0 meaning “no fatigue” and 10 meaning “fatigue as bad as you can imagine.” Scores of all 9 items yield global fatigue burden. A lower average global fatigue score indicates milder fatigue and a higher score severe fatigue.

Secondary Measures

  • Handgrip strength test
    • Time Frame: Baseline to 17 weeks
    • Change in handgrip strength measured by a dynamometer in lbs
  • Trail Making Test (TMT)
    • Time Frame: Baseline to 17 weeks
    • Change in minutes to complete Trail Making Test (TMT) A and B
