Malnutrition Screening by Muscle Ultrasound in Patients Requiring Mechanical Ventilation in Intensive Care Unit — MALICUS  

Critical Illness Clinical Trial

Official title:
Ultrasound Measurement of the Quadriceps Muscle Diameter for the Detection and the Follow-up of Malnutrition in Patients Receiving Mechanical Ventilation in Intensive Care Unit

Clinical Trial Summary

Malnutrition is a major risk factor for morbidity and mortality of patients managed in intensive care unit. Early recognition and treatment of adult malnutrition are recommended in acute care settings especially for patients requiring mechanical ventilation. Biochemical indicators like serum concentrations of albumin and prealbumin (transthyretin) have a tradition of being used as markers of nutritional status but remains influenced by nonnutritional factors. A recent assessment of quadriceps muscle diameter with ultrasound method has gained interest for screening and follow-up of muscle weakness at the bedside in critically ill patients. In this light, the MALICUS project aims to investigate the validity of ultrasound as measurement tool for assessing malnutrition acquired in intensive care unit. Skeletal muscle is central to cytokine regulation and it contributes 85% of total body glucose clearance. Some research findings suggest that muscle wasting is a smoldering inflammatory state partially driven by cytokines and oxidative stress but these conclusions need to be investigated in context of critically ill patients and perioperative settings. The investigators search to determine impact of inflammatory biomarkers (IL-1, IL-6 and TNF-α) and oxidative stress (evaluated by quantifying the global anti-oxidative defenses in patient with an original method (Patrol® test) based on the use of excited molecular oxygen (singlet oxygen) as a source of ROS on erosion of lean body mass measure with quadriceps muscle ultrasound. Consequently, in an ancillary study of the MALICUS project, the investigators wish to investigate interaction between acute inflammation and muscle wasting.
