Background
The role of generalized health biomarkers remains widely unexplored in relation to TBI. However, they show association with worsened brain health and nervous system functioning. It is useful to explore potential relationship between TBI and generalized, circulating health biomarkers as surrogate endpoints that can be linked to severity and mortality.
Aim
This is a hypothesis-free study that investigates the potential relationship(s) between traumatic brain injury and 34 generalized, circulating health biomarkers using data collected by the UK Biobank.
Methods
Data from 419,778 white British participants are analyzed against 34 biomarkers from the UK Biobank database. TBI diagnosis is captured through ICD-10 codes and categorized as narrow-band and broad-band TBI. Multivariate linear regression analysis is conducted for changes in biomarkers in participants with TBI history vs. those with no history. This is analyzed across 4 models with increasing number of covariates and stratified for both categories of TBI.
Results
IGF-1, gamma glutamyltransferase and aspartase aminotransferase had significant results across all models in broad-band and narrow-band TBI (P < 0.05). An additional ten biomarkers showed statistically significant results in all models except the fully adjusted models.
Conclusion
