Article Synopsis
  • There is significant interest in using blood biomarkers as quick and objective diagnostic tools for traumatic brain injury (TBI) during critical care.
  • A study conducted at Turku University Hospital involved adult TBI patients and assessed several biomarkers to determine their effectiveness in distinguishing between different severities of TBI.
  • Results showed that while there were notable differences in biomarker levels among severity classes, none could effectively differentiate between moderate and severe TBI, nor discern CT-positive from CT-negative cases in patients with mild TBI.

Blood biomarkers may enhance outcome prediction performance of head computed tomography scores in traumatic brain injury (TBI). To investigate whether admission levels of eight different protein biomarkers can improve the outcome prediction performance of the Helsinki computed tomography score (HCTS) without clinical covariates in TBI. Eighty-two patients with computed tomography positive TBIs were included in this study.

Patients with traumatic brain injury (TBI) exhibit a variable and unpredictable outcome. The proteins interleukin 10 (IL-10) and heart fatty acid-binding protein (H-FABP) have shown predictive values for the presence of intracranial lesions. To evaluate the individual and combined outcome prediction ability of IL-10 and H-FABP, and to compare them to the more studied proteins S100β, glial fibrillary acidic protein (GFAP), and neurofilament light (NF-L), both with and without clinical predictors.

The aim of the study was to examine the ability of eight protein biomarkers and their combinations in discriminating computed tomography (CT)-negative and CT-positive patients with traumatic brain injury (TBI), utilizing highly sensitive immunoassays in a well-characterized cohort. Blood samples were obtained from 160 patients with acute TBI within 24 h of admission. Levels of β-amyloid isoforms 1-40 (Aβ40) and 1-42 (Aβ42), glial fibrillary acidic protein (GFAP), heart fatty-acid binding protein (H-FABP), interleukin 10 (IL-10), neurofilament light (NF-L), S100 calcium-binding protein B (S100B), and tau were measured.

The purpose of this study was to correlate the early levels of glial fibrillary acidic protein (GFAP) and neurofilament light protein (NF-L) with outcome in patients with mild traumatic brain injury (mTBI). A total of 107 patients with mTBI (Glasgow Coma Scale ≥13) who had blood samples for GFAP and NF-L available within 24 h of arrival were included. Patients with mTBI were divided into computed tomography (CT)-positive and CT-negative groups.

Article Synopsis
  • - Mild traumatic brain injury (mTBI) patients can sometimes have detectable brain lesions via CT scans, but many don't show any visible issues, highlighting the need for better detection methods.
  • - The study examined 13 different proteins to identify which ones could help differentiate between mTBI patients with and without brain lesions; ultimately, four proteins (H-FABP, IL-10, S100B, and GFAP) were found to be effective, with H-FABP showing the highest performance.
  • - Combining H-FABP and GFAP into a blood biomarker panel improved detection accuracy for CT-positive patients, with additional success when adding IL-10, achieving 100% sensitivity and a specificity of up to

Traumatic brain injury is a common event where 70%-90% will be classified as mild TBI (mTBI). Among these, only 10% will have a brain lesion visible via CT scan. A triage biomarker would help clinicians to identify patients with mTBI who are at risk of developing a brain lesion and require a CT scan.

The majority of patients with mild traumatic brain injury (mTBI) will have normal Glasgow coma scale (GCS) of 15. Furthermore, only 5%-8% of them will be CT-positive for an mTBI. Having a useful biomarker would help clinicians evaluate a patient's risk of developing intracranial lesions.

Accurately determining time-of-onset of cerebral infarction is important to clearly identify patients who could benefit from reperfusion therapies. We assessed the kinetics of peroxiredoxin 1 (PRDX1), a protein involved in oxidative stress during the acute phase of ischemia, and its ability to determine stroke onset in a population of patients with known onset of less than 24 hours and in a control group. Median PRDX1 levels were significantly higher in stroke patients compared to controls.

Background: Inflammation is known to worsen cerebral damage at the acute phase of stroke. In this setting, cell adhesion molecules (CAMs) play a crucial role mediating migration of immune cells into the infarcted area. However, their value in long-term outcome prediction for patients with cerebrovascular diseases (CVD) is less described.
