Effects of Nutritional Supplementation on Protein and Energy Homeostasis in Malnourished Chronic Hemodialysis Patients

The goal of this study is to evaluate the metabolic effects of concomitant use of three consecutive doses of recombinant human growth hormone over three days and exercise during continuous nutrient infusion in chronic hemodialysis patients. We would also like to evaluate the metabolic effects of nutritional supplementation alone without the additional anabolic strategies.

Treatment and study plan

Nutritional Supplement

Dietary Supplement

either oral nutritional formula (Nepro) or intravenous IDPN solution will be administered during hemodialysis; Nepro has a total calorie amount as well as protein, carbohydrate and fat content that are comparable to that of IDPN, and will be provided at four equal amounts with 1-hour intervals throughout the study (150 ml for a total of 600 ml over 4 hours of hemodialysis); IDPN consists of 225 ml of amino acids at a concentration of 15%, 112.5 ml of dextrose at 50% and 112.5 ml of lipids at 20%, will be given at a rate of 150 ml/hr, and will provide 209 kcal/hr

recombinant human growth hormone (rcGH)

Drug

subcutaneous administration of 75 micrograms/kg/day of rcGH for 3 consecutive days

Exercise

Behavioral

either dual leg press (3 sets of 8-12 repetitions) beginning 30 minutes prior to hemodialysis, or modified stepper (minimum of 15 minutes up to a maximum of 90 minutes, depending upon the patient's tolerance) beginning 15 minutes post initiation of hemodialysis

Primary outcomes

  1. net muscle protein balance

    Time frame: 10 hours

Secondary outcomes

  1. net whole body protein balance

    Time frame: 10 hours
