Summary

The purpose of this study is to determine whether patients with acute kidney injury requiring renal replacement therapy have a higher incidence of muscle wasting than controls and whether the course of recovery is longer compared to controls.

Detailed description

Acute kidney injury (AKI), the abrupt loss of kidney function, is a common complication that affects more than half of all intensive care unit (ICU) admissions, and it is associated with substantially higher rates of morbidity and mortality in both the short- and the long-term. This is especially true in patients with AKI requiring renal replacement therapy (AKI-RRT), also known as dialysis. An understudied mechanism by which AKI-RRT may contribute to poor clinical outcomes, both in the hospital and after discharge, is through its impact on muscle mass and muscle function. AKI of any severity is known to alter tissue utilization of amino acids, and preliminary data suggest that RRT in the ICU may exacerbate muscle dysfunction through the removal of large quantities of amino acids from the patient's plasma. This study will determine whether patients with AKI-RRT have greater lean muscle loss over 1 week than historical critically ill controls, whether patients with AKI-RRT have diminished recovery of muscle mass and function at 1-3 months following discharge compared to controls, and whether changes in plasma levels of amino acids during hospitalization correlate with loss of muscle function or lack of recovery.

Conditions

• Acute Kidney Injury
• Critical Illness Myopathy
• Dialysis; Complications

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Musculoskeletal ultrasound	Ultrasound of rectus femoris to determine cross-sectional area, muscle thickness, echo intensity.
DIAGNOSTIC_TEST	Assessments of muscle strength and physical function	A battery of tests of physical function and muscle strength (see outcomes section for details).
DIAGNOSTIC_TEST	Metabolomics	Using metabolomic analysis, concentrations of amino acids and other important analytes will be measured in patient plasma and CRRT effluent
