Alterations in Protein Synthesis Rates of Burn Patients Measured Over Time Using PET Scans

Burn Clinical Trial

Official title: A Quantitative Study of the Metabolic Alterations in Protein Synthesis Rate That Occur in Burn Patients Over the Time Course of Their Injury Using Positron Emission Tomography.

Status Not yet recruiting

Clinical Trial Summary

Our specific aim is to gain an understanding of protein synthesis rates in burn patients at various times during their injury and recovery by using PET scans. This will be compared with healthy volunteer controls. We hope this will help optimize nutrition and care regimens for future burn patients.

Clinical Trial Description

The purpose of this study is to understand how muscles are built up and broken down (metabolism) in both burn patients and healthy people.The studies will help us understand how muscle metabolism is different for burn patients and healthy subjects. We hope to find ways to help the body of a burn victim heal without losing too much muscle.

Protein is an important part of our daily diet. Normally, the body breaks down the protein we eat into smaller pieces called amino acids. It uses the amino acids to make its own proteins. It uses these proteins to heal wounds, fight infections, and provide energy.

After a burn injury, the body speeds up the pace of its life activities. It needs more energy just to stay alive and recover from the burn. The body often gets the extra energy it needs by breaking the protein in muscles down into amino acids. The amino acids are then made into new proteins. If too much muscle is broken down, it is harder for the body to function. This can make recovery slower or possibly lead to death.

For Healthy Volunteers, this study will require no more than 6 hours of time in total. This time will be spread out over two visits, a Screening Visit and a Scan Visit.

For Burn Patients, this study will require no more than 14 hours total. This time will be spread out over four visits-a screening visit and a maximum of 3 scan visits. A total of three PET scans will be done over a 2 year period. ;
