Filter by: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.
Various diagnostic methods are available for CMV infection. But none of them could be a standard and highly valuable. Our first goal is to setup a series of molecular diagnostic tools for HIV-1 infected person. By using these tools, physicians can easily select cases with CMV disease or immune restoration inflammatory syndrome (IRIS) to enroll this study. Furthermore, we will seek for a predict marker for CMV reactivation, CMV disease and IRIS. Finally, our research will focus on the mechanism of the IE gene alternative splicing between lytic and latent stage.
Cytomegalovirus (CMV) infects most of the world population. This study is to understand if chemotherapy will increase the chance of reactivating CMV. The results may help us in determining when treatment is needed and perhaps Why is it needed.
The rationale for this protocol is based on the need to assess if the current post stem cell transplantation CMV prophylaxis strategies (e.g. high-dose acyclovir plus pre-emptive treatment) can be improved by the use of valganciclovir. CMV is the most common viral infection following stem cell transplantation, causing significant morbidity and mortality. Furthermore, CMV has been shown to be associated with a number of indirect effects in SCT recipients including allograft dysfunction, acute and chronic graft versus host disease (GVHD). Valganciclovir is shown to be more active than oral ganciclovir, and as good as intravenous (i.v.) ganciclovir in treating newly diagnosed CMV retinitis. The use of valganciclovir for CMV prophylaxis post stem cell transplantation was never tested in controlled study. The investigators therefore suggest a prospective, randomized study to evaluate the efficacy and safety of valganciclovir compared with acyclovir for prevention of CMV disease in allogeneic stem cell transplantation recipients.
This pilot study is to assess whether using CytoGam® in combination with ganciclovir is more effective in reducing the CMV viral load over time, as compared to standard treatment with IV ganciclovir only. Serial blood samples are drawn to measure the amount of CMV viral load weekly, while the subject is receiving treatment with ganciclovir, or ganciclovir + CytoGam®. Additional CMV viral load blood sampling (CMV DNA capture qualitative testing only) will occur weekly thereafter until the subject is 8 weeks from the time of CMV diagnosis or until the CMV infection is no longer detectable, whichever is longer duration.
