Clinical Trial Summary

Background: Patients with critical illness in the intensive care unit (ICU) experience marked skeletal muscle weakness, muscle atrophy and disability in physical function, commonly termed ICU-acquired weakness (ICU-AW). The pathophysiology of ICU-AW is complex, but a key feature of skeletal muscle wasting is disturbed protein metabolism reflected in both increased rate of muscle protein degradation and reduced synthesis. Treatment with 3-OHB seems a promising new anticatabolic treatment in patients with critical illness, preventing ICU-AW. To date, no data exist on the clinical and functional effects of ketone body modulation in patients with critical illness. Objective: The aim to investigate the effect of exogenous 3-OHB administration on muscle protein kinetics and lipolysis in patients with critical illness, aiming towards preventing ICU-AW. Design: A randomized double-blind isocaloric placebo-controlled cross-over study in 10 mechanically ventilated patients with critical illness in the ICU. Methods: Evaluation of whole-body and focal leg protein kinetics using labeled phenylalanine and tyrosine tracers. Assessment of free fatty acid (FFA) turnover using a labeled palmitate tracer. Femoral arterial blood flow (assessed with pulsed-wave Doppler ultrasound) is evaluated once per study period. Blood- and urinary samples are collected routinely throughout the study day. Whenever feasible, muscle and fat biopsies will be taken for analysis of protein and adipocyte metabolic signaling and mitochondrial function. Perspectives: This investigation may grant essential knowledge on ketosis in critical illness. This may lead to larger clinical trials, and hopefully a new and better treatment strategy aimed at preserving muscle mass and function during and improving recovery after critical illness.
