Effect of Glutamine Supplemented Nutrition Support on Protein and Glutamine Metabolism in Burns

Burns Clinical Trial

Official title:
Study on the Effect of Glutamine Supplemented Nutrition Support on Protein and Glutamine Metabolism in Severely Burned Patients

Clinical Trial Summary

The Total Parenteral Nutrition (TPN)received as part of your routine burn care has optimal levels of protein and sugar, however the best mixture of amino acids for a patient with burn wounds is not yet known. Amino acids occur naturally in the body and the food we eat. The body combines amino acids to make protein. It uses the proteins to do things such as heal wounds, fight infection, and provide energy. We are studying if the body's use of protein is increased after receiving TPN containing the amino acid called glutamine. We hope to learn the best composition of TPN so that the body can more efficiently repair wounded tissues and recover earlier from an acute burn injury.

Clinical Trial Description

Human and animal studies have demonstrated that glutamine catabolism exceeds glutamine synthesis in burn patients, resulting in a glutamine-depleted status, which compromises liver function, including glutathione status, proline and arginine homeostasis and whole body protein balance (1). The purpose of this study is to directly quantify glutamine / glutamate kinetics in relation to glutamine / glutamate disposal and whole body amino acid balance, by using stable isotope tracers [1-13C, 15N]leucine and [15N2]urea.

We hypothesize that the enrichment of amino acid mixtures with glutamine will attenuate overall body nitrogen catabolism and better maintain proline and arginine homeostasis.

The purpose of this study it to 1) investigate the effect of glutamine supplemented total parenteral nutrition (TPN) on whole body metabolic and disposal rate of glutamine, and its rate of de novo synthesis in severely burned patients and 2)explore the impact of glutamine supplementation on whole body protein turnover, studied with L-[1-13C, 15N}-leucine, and on the metabolic homeostasis of urea cycle. ;
