Identification of the Epigenetic Response to Trauma — TrauMeth  

Trauma Clinical Trial

Official title:
Identification of the Epigenetic Response to Trauma - a Prospective, Observational Study

Clinical Trial Summary

The objective of this study is to investigate potential early alterations in the DNA methylation profile after severe trauma and to investigate if the early marks persist.

Clinical Trial Description

Background: Severe trauma is an extreme physical exposure, which may have significant consequences for the patient. In addition to anatomical injury and hemodynamic compromise, severe trauma causes an immense and rapid systemic immune reaction. At the genomic level, trauma has been found to significantly increase gene expression in circulating leukocytes, and preliminary data is also emerging that trauma may even cause epigenetic (DNA methylation) alterations. Epigenetics, including DNA methylation, have been suggested as a mediator of genetic risk and to play a significant role in subsequent non-traumatic disease. Within the field of trauma DNA methylation has only been sparsely studied, but a few studies of traumatized animals have suggested that DNA methylation alterations may occur in relation to trauma. Even though DNA methylation is highly dynamic, some marks have been found to be stable over time, and thus may have long-term consequences. An increasing understanding of the role of epigenetics in disease development and response may pave the way for new treatment targets and modalities for multiple diseases including trauma. Research question: Does trauma induce immediate (<4 hours) and persistent (30 days post-trauma) changes in the epigenome of peripheral blood cells, and do epigenetic changes correlate with patient recovery? Objectives: To identify potential early alterations in the DNA methylation profile after severe trauma AND to investigate if the early marks persist. Study design: A prospective, observational, cohort study of trauma patients admitted to RH's trauma center. The trauma cohort will be compared to a cohort of patients admitted for elective orthopedic surgery in terms of DNA methylation profile in blood cells pre-trauma/surgery, immediately post-trauma/surgery, and 30-45 days post-trauma/surgery. DNA methylation profiles will be assessed by array technique using Illumina's MethylationEPIC Bead-Chip. Primary outcome: Immediate (<4 hours) post-trauma DNA methylation profile in blood cells. Secondary outcomes: Pre-trauma/surgery DNA methylation profile, change in DNA methylation from pre-trauma/surgery to immediately and 30 days post-trauma/surgery, occurrence of organ dysfunction, sepsis, septic shock, 30-day mortality, ICU admission > 24 hours, ICU length of stay (LOS), hospital LOS. ;
