Assessing muscle metabolism and insulin resistance in dialysis patients through exercise

Contribution of Plasma Assays of Biomarkers of Muscle Metabolism During Exercise to the Assessment of Insulin Resistance in Chronic Renal Failure Patients Undergoing Hemodialysis.

Not applicable Interventional University Hospital, Montpellier · NCT06360302

This study is testing how exercise affects muscle metabolism and insulin resistance in dialysis patients compared to those with metabolic syndrome and healthy people to help improve treatment strategies.

What this trial studies

This study compares the biochemical and functional responses to exercise in chronic kidney disease (CKD) dialysis patients, patients with metabolic syndrome, and healthy subjects. It aims to identify plasma metabolic intermediates associated with insulin resistance to improve the assessment of muscle oxidative metabolism. By utilizing a metabolomics approach during exercise, the study seeks to create a biological and functional profile that distinguishes between insulin-resistant patients and healthy controls. The findings could enhance understanding of metabolic abnormalities in CKD patients and inform muscle rehabilitation strategies.

Who should consider this trial

Good fit: Ideal candidates include postmenopausal women and men aged 40 to 75, specifically those who are non-diabetic CKD dialysis patients, patients with metabolic syndrome, or healthy individuals without chronic diseases.

Not a fit: Patients with non-stabilized pathologies incompatible with physical exercise or those currently undergoing exercise retraining programs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved assessment and management of insulin resistance in CKD patients, potentially enhancing their rehabilitation outcomes.

How similar studies have performed: While the approach of using metabolomics in exercise assessments is innovative, similar studies have shown promise in understanding metabolic disorders, suggesting potential for success.
