About this study

Official title: The Association Between Initial Concentrations of Biomarkers and Outcome 1 and 10-15 Years After Severe Traumatic Brain Injury

After written consent from next-of-kin patients with severe traumatic brain injury was included from the neurointensive care unit (NICU) at Sahlgrenska university hospital, Gothenburg. Blood and CSF samples were collected during the initial 3 weeks after trauma. 1 year after trauma patients were assessed according to Glasgow outcome scale (GOS), NIHSS and Barthels. 10-15 years after trauma a repeated evaluation according to GOS was performed by telephone. Different biomarkers such as Neurofilament light, Glial fibrillary acidic protein and Tau among others, was analyzed from serum and CSF samples. Further patients were explored Apolipoprotein-E genetype (APOE). The investigators hypothesize that higher biomarkers concentrations and positive test for this gene relate to worse outcome 1-year and 10-15 years after trauma. Further that these biomarkers and genetic marker further have prognostic value on outcome 1-year and 10-15 years after trauma. Finally, the investigators want to explore the concentrations dynamics of these biomarkers in serum and CSF in the acute phase after trauma.

Read the detailed description

Patients with a severe traumatic brain injury (sTBI) were included after written consent from next-to kin. The injury was considered as severe if having a Glasgow coma scale of 8 or less. Within 48h of trauma patients were included from the neurointensive care unit at Sahlgrenska university hospital, Gothenburg during 2000-2004. Patients were intubated and had a ventricular catheter. All patients were treated in accordance with the Lund Concept. Samples from ventricular cerebrospinal fluid (CSF) and blood was collected, during the first 3 weeks, then prepared for storage and later analyzed. Samples were stored in -70 degrees Celsius until analyzed. 1 year after trauma patients were assessed according to Glasgow outcome scale (GOS), NIHSS and Barthels Index. 10-15 years after trauma an evaluation of GOS by phone was repeated. Biomarkers such as Neurofilament light, Glial fibrillary acidic protein, Tau among others is analyzed in serum and CSF. Further, patients APOE genotype was explored. The investigators hypothesizes that higher concentrations of these biomarkers both in serum and CSF relate to worse 1-year and 10-15 year outcome after a severe traumatic brain injury. Further, patients that have the gene APOE4 is predisposed to worse 1 year and 10-15 year outcome after a sTBI. The investigators further want to explore the dynamics of these biomarkers in serum and CSF in the acute phase after trauma and if these biomarkers gave any prognostic value to on outcome (mortality and functional) 1-year and 10-15 years after trauma.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. In severe traumatic brain injury patient; Correlation of Neurochemical biomarkers analyzed in CSF and serum, assessed in the initial ICU period, correlated to Glasgow Outcome Scale (GOS) at 1 year post-trauma

    GOS 1-3 - Poor outcome, GOS 4-5 Good outcome

    Measured: 1 year after trauma

  2. In severe traumatic brain injury patient; Correlation of Neurochemical biomarkers analyzed in CSF and serum, assessed in the initial ICU period, correlated to Glasgow Outcome Scale (GOS) at 10-15 years post-trauma

    GOS 1-3 - Poor outcome, GOS 4-5 Good outcome

    Measured: 10-15 years after trauma

  3. In severe traumatic brain injury patient; correlation of the genetic alleles of APOE correlated to Glasgow Outcome Scale (GOS) at 1-year post-trauma)

    GOS 1-3 - Poor outcome, GOS 4-5 Good outcome

    Measured: 1 year after trauma

  4. In severe traumatic brain injury patient; correlation of the genetic alleles of APOE correlated to Glasgow Outcome Scale (GOS) at 10-15 years post-trauma)

    GOS 1-3 - Poor outcome, GOS 4-5 Good outcome

    Measured: 10-15 years after trauma

Questions about this trial

What is this clinical trial studying?

An observational study of Brain Injury Traumatic Severe (Diagnosis) and Biomarkers, run by Bengt Nellgard at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In severe traumatic brain injury patient; Correlation of Neurochemical biomarkers analyzed in CSF and serum, assessed in the initial ICU period, correlated to Glasgow Outcome Scale (GOS) at 1 year post-trauma (time frame: 1 year after trauma). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05138692, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Dec 2021.
