Biomarkers in severe traumatic brain injury: enhancing prognostic accuracy and therapeutic strategies

This study examines the emerging role of biomarkers in the prognosis and management of severe traumatic brain injury (sTBI). Key findings highlight the significance of serum RIP-3, STC1, Nrf2, and cerebrospinal fluid galectin-3 and cytokines in predicting disease severity, mortality, and functional outcomes in sTBI patients. Elevated levels of RIP-3 and STC1 were linked to poor prognosis and increased mortality, with RIP-3 associated with necroptosis and inflammation, and STC1 with neuroprotective properties. Nrf2 was found to correlate with oxidative stress and adverse outcomes, while elevated CSF galectin-3 and IL-6 indicated neuroinflammation and neurodegeneration. These biomarkers show promise not only as prognostic tools but also as potential therapeutic targets. The study suggests further validation through multicenter research to enhance clinical applications and improve treatment strategies for sTBI.
