Metabolism and muscle recovery after an ICU stay

Characterisation of the Inflammatory, Metabolic, and Mitochondrial Profiles in the Context of Post-Intensive Care Muscle Dysfunction

Not applicable Interventional University of Liege · NCT07329530

We will test whether blood and muscle metabolic and inflammatory markers can help predict how well adults recover muscle strength over three months after an ICU stay or major abdominal surgery.

What this trial studies

This single-center study recruits adults who survived a critical illness with an anticipated ICU stay of seven days or more and elective major abdominal surgery patients as a comparison group. Investigators will collect blood samples for inflammation markers, nucleosomes, erythrocyte membrane fatty acids, and myokines, and measure resting energy expenditure. Muscle performance will be measured at discharge and followed over three months, with muscle biopsies, bioelectrical impedance, and indirect calorimetry used when feasible. The goal is to link metabolic and neuroendocrine profiles to trajectories of muscle function after ICU discharge.

Who should consider this trial

Good fit: Adults who survived a critical illness with an anticipated ICU stay of at least seven days or adults undergoing elective major abdominal surgery who can provide informed consent are ideal candidates.

Not a fit: Patients with active malignancy, known muscle or inherited metabolic disorders, pregnancy, inability to consent, or contraindications to muscle biopsy, bioelectrical impedance, or indirect calorimetry are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could help identify patients at high risk for prolonged muscle weakness so they can receive earlier or more targeted rehabilitation.

How similar studies have performed: Prior studies have shown persistent inflammation and associations with ICU-acquired muscle weakness, but comprehensive metabolic and myokine profiling to predict individual recovery trajectories is relatively novel.
