Effect of Burn Size on Cytomegalovirus Reactivation and Correlates of T Cell Immune Function in Burned Patients
The purpose of this study is to evaluate the effect of burn injury on the human immune system with a focus on cytomegalovirus (CMV) reactivation and the immunologic correlates of latent viral reactivation.
Subjects will be patients admitted to the North Carolina Jaycee Burn Center with burn injury.
Blood samples will be collected over time and will be evaluated for CMV reactivation and immune cell phenotype.

The purpose of this research study is to learn about infections and the immune system in people who suffer from burn injuries. The immune system changes after burn injury and infection is one of the most common complications. Cytomegalovirus (CMV) is a virus that most people are exposed to early in life; once you are exposed it lays inactive in your body forever. When the immune system is suppressed, this virus can reactivate. We would like to measure how this virus makes copies of itself in the blood stream in people with a burn injury and to look at cell markers of the immune system.
This study involves baseline and weekly blood draws for approximately 8 weeks. If blood tests show CMV infection, further monitoring of blood work may be needed after eight weeks.
