Posttraumatic Changes in Energy Expenditure and Body Composition in Patients With Acute Spinal Cord Injury
Severe trauma induces massive metabolic changes that are characterized by hypermetabolism with increased energy expenditure and catabolism. Early enteral and, if necessary, parenteral feeding is a major focus of modern intensive care medicine.
After acute spinal cord injury, denervation of skeletal muscle leads to a massive loss of muscle mass in the area below the level of injury. This dramatic muscle atrophy again leads to a decrease in energy expenditure. Whereas other survivors of severe trauma typically regain muscle mass during rehabilitation, spinal cord injury patients typically continue to lose muscle mass over time, which also leads to changes in body composition. The time course of these changes is not known. Continuing nutrition without adaption to the reduced energy expenditure leads to weight gain and adiposity, exposing many chronic spinal cord injury patients to the known unfavorable metabolic consequences. Knowledge of the time course of these changes would help to provide adequate caloric intake to the patients and improve our ability for nutrition counseling.
The investigators plan a prospective clinical trial in 25 acute spinal cord injury patients to determine the changes in energy expenditure and body composition. Major inclusion criteria are acute traumatic spinal cord injury, age 18-70, neurological level above L1, AIS (American Spinal Injury Association Impairment Scale) A, B or C.
Measurements of energy expenditure, body composition and nutritional markers in venous blood are scheduled 2, 6, 10 and 14 weeks after spinal cord injury and at the end of rehabilitation (at the latest after 26 weeks).
