Forearm muscle protein homeostasis dynamic components during HD, comparing control (□), IDPN (), and PO (■) in 8 CHD patients with deranged nutritional status. Skeletal muscle protein homeostasis during HD improved with both IDPN and PO versus control (P = .005 and .009 for IDPN versus control and PO versus control, respectively). Oral supplementation resulted in persistent anabolic benefits in the post-HD phase for muscle protein metabolism, when anabolic benefits of IDPN dissipated (data not shown in figure). Units are ug/100 mL/min. *P < .05 versus control. Adapted with permission from American Society of Nephrology.18
