Definitions
- the invention relates to biomarkers and novel biomarkers, their use in diagnostics of brain injury or brain related injuries, in particular mild traumatic brain injury (mTBI), and methods as well as devices for the detection of same in an individual.
- mTBI mild traumatic brain injury
- mTBI traumatic brain injury
- CT computer tomography
- a mild traumatic brain injury is a type of closed head injury, defined as the result of a blunt trauma or acceleration/deceleration forces causing a brief change in mental status (confusion, disorientation or loss of memory) or loss of consciousness for less than 30 minutes.
- loss of consciousness is very brief and ranges between a few seconds to minutes.
- Mild TBI remains the biggest percentage of ail closed head, brain injury cases admitted to the hospitals.
- the primary criterion for evaluating patients with TBI in clinical setting is the Glasgow Coma Scale (GCS), which assesses the level of consciousness following TBI.
- GCS Glasgow Coma Scale
- a mild traumatic brain injury is most likely to be diagnosed only when there is a change in the mental status at the time of injury or hospital admission (the person is dazed, confused, or loses consciousness, GCS score 13-15).
- GCS score 13-15 the person is dazed, confused, or loses consciousness, GCS score 13-15.
- GCS severe head injury
- GCS 9-12 10% as moderate
- GCS 13-15 mild TBI
- biomarkers has been proposed as a means to reduce the amount of unnecessary CT scans (Berger et al. 2007; Poli-de-Figueiredo et al., 2006) and for use in decentralized sites where access to CT equipment is absent.
- biomarker-assay is available which gives test results capable of properly classifying the majority of patients and therefore useful in serial screening.
- the method of choice today is a CT scan due to the insufficient reliability and high percentage of false negative results with known biomarkers for TBI detection.
- One such known biomarker is S100B.
- S100B is a low-molecular-weight (9-13 kDa), non-ubiquitous Ca2+-modulated protein implicated in e.g. regulation of enzyme activities, dynamics of cytoskeleton elements, cell growth and differentiation and Ca2+ homeostasis (Donato R., 2003).
- CNS central nervous system
- Significantly increased S100B levels are associated with severe TBI and may reflect ongoing structural damage and cell death after injury (Ingebrigtsen et al. 2002, Missler et al, 1999).
- one object underlying the present application is to provide for alternative or new feasible biomarkers for the detection or/and classifying of any brain related traumatic state and in particular for mTBI, and for assays and devices useful and reliable therefore and in mTBI diagnostics which can be used in a clinical or non-clinical context, or to improve known approaches to neurological or mTBI screening and analysis.
- the invention provides a method, composition, kit, assay for the classifying or detection of brain injuries or disorders or diseases like TBI, transient ischemic attack, brain tumors, seizures, epilepsia, cerebral abscess, encephalopathies and multiple sclerosis by use of a combination of markers like glutathione S transferase Pi (GSTP), fatty-acid-binding protein (FABP), glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE), neuromodulin (GAP43), neurofilament protein H (NFH), neurofilament protein M (NFM), neurofilament protein L (NFL), S100B, Tau, spectrin breakdown products, ubiquitin carboxyl terminal hydrolase-L1 (UCH-L1 ), vascular cell adhesion protein 1 (VCAM), serum amyloid A (SAA), Chemokine (C-C motif) ligand 23 (CCL23), peroxiredoxin 1 to 6 and nucleoside di
- the present invention provides a combination of a selection of blood brain biomarkers (GSTP1 , H-FABP, VCAM, ND A) optionally combined to the known (and not sufficiently specific) S100B for reliable detection of brain injury like a disease or disorder selected from the group consisting of TBI, transient ischemic attack, brain tumors, seizures, epilepsia, cerebral abscess, encephalopathies and multiple sclerosis in a sample and in particular for mTBI detection.
- these biomarkers were combined and adjusted in panels yielding specificity above 50% at a fixed sensitivity of 95% or 100%. This will allow clinicians and also on site medical emergency staff to better manage the detected diseases or disorders and in particular mild TBI patients and therefore potentially reduce CT scans but also the consequences associated with a delayed diagnosis of brain injury.
- the invention concerns devices, e.g. biomarker panels, to detect early traumatic brain injury (TBI) lesions better or complement S100B to rule out CT scans in mild TBI patients.
- TBI traumatic brain injury

- Fig. 7 shows a comparison of S100B (specificity 37%) and a combination of
- HFABP+VACM (specificity 59%) for a 100% sensitivity in a cohort of mTBI patients
- Fig. 8 shows the advantage of using the biomarkers of the invention to avoid costly CT scans in a clinical setup.
- the invention relates to a methodfor screening for a disease or disorder selected from the group consisting of TBI, transient ischemic attack, brain tumors, seizures, epilepsia, cerebral abscess, encephalopathies and multiple sclerosis in a specimen (sample) comprising the steps of using a sample under suitable conditions and detecting at least two biomarkers under suitable conditions wherein the biomarkers are selected from the group consisting of glutathione S transferase Pi (GSTP), fatty-acid-binding protein (FABP , glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE), neuromodulin (GAP43), neurofilament protein H (NFH), neurofilament protein M (NFM), neurofilament protein L (NFL), S100B, Tau, spectrin breakdown products, ubiquitin carboxyl terminal hydrolase-L1 (UCH- L1), vascular cell adhesion protein 1 (VCAM), serum amyloid A (SAA), Che

- Another advantageous embodiment is a combination with the molecule markers as described herein with other markers like age or GCS.
- the markers according to the invention in a particular patient group characterized by GCS score of 13 or more or 15 or more, or in a particular age group, e.g. 60 years or more, 65 years or more, 70 years or more will yield very positive and highly reliable test results. More so, in this manner the invention positively achieves that reliable test results can be achieved by the use of less molecular markers which does not only have technical advantages but is also advantageous from a cost point of view.
- the invention provides the unexpected advantage that a brain injury and the particular medical complications as described herein can be identified and screened for not only in a fully equipped hospital but by use of a simple test device anywhere and without the use of qualified medical personnel.

- the method and system are capable to analyze at least two test results in a sample of an individual, useful for the diagnosis of a medical condition like brain injury, with the system comprising:
- the blood GSTP1, H-FABP, NDKA, VCAM and S100B content of patients presenting or not cerebral lesions on CT scan with a Glasgow Coma Scale > 13 and within 6 hours after the onset of TBI were quantified and compared using ELISA analysis.
- the study population comprised a total of 97 individuals.
- ELISA was performed using 96-well homemade assays for GST-Pi and NDKA as described elsewhere (Turck, et al. 2012), H-FABP from Hycult (NL) and CCL23, SAA, peroxiredoxin 1 and S100B from Abnova (TW). Each plasma sample were assayed in duplicate and distributed randomly on the plates.
- Protein levels were initially expressed in relative fluorescence unit (RFU) and concentrations were calculated using a calibration curve obtained on the same plate with the recombinant proteins.
- Statistical analyses were performed using IBM SPSS Statistics software version 19.0.0 (IBM Corporation, NY, USA). To assess the ability of proteins to discriminate between different populations, non-parametric tests were performed. A Wilcoxon matched pairs test was performed for age and sex matched data and a Mann-Whitney for non-matched data. For data containing more than two groups, a one-way ANOVA Kruskal-Wallis test was used. Receiver Operating Characteristic (ROC) curves analysis was performed and cut-off (CO) points obtained from the curves. Optimal threshold values were chosen to provide the highest specificity for 100% sensitivity. Multivariate logistic regression analysis was used to compare the values of plasma S100B, H-FABP, GST-Pi, VCAM, CCL23, SAA, peroxiredoxin 1 and NDKA levels as CT scan rule out markers.
- ROC Receiver Operating
- each member of the panel provides a different angle to the diagnosis and taken together they lead to a more accurate prediction.
- Each member of the panel fulfils several criteria: firstly it must have a predictive power itself, i.e. it must be able to distinguish the disease types to a certain extent. Secondly it must be easy to measure with high reproducibility. Thirdly, it should have a central role in the biological processes that were found by the network analysis.
- the figures as described above show the results of the specificity comparison of S100B alone vs. different panels of two or three molecules/biomarkers of the invention.
- the sensitivity has been set at 100%. It demonstrates that our cohort is comparable to all published mTBI cohorts analysing S100B. When sensitivity is set at 100%, a 37% of specificity is obtained.
- GSTP and HFAB have a specificity of 25%, NDKA of 12% and VCAM of 40%. This confirms all previous results on the limited capacity of S100B alone to rule-out negative CT patients and the need of additional parameters/biomarkers.
- the surprising and unexpected advantage is an improved specificity (>50%) for 100% sensitivity to rule out CT scans in mild TBI patients using a panel of two or three markers within S100B, GSTP, HFABP, VCAM, CCL23, SAA, peroxiredoxin 1 and NDKA.
- Results in a patient group which includes only patients with an age of above 61 years are depicted in the following:
