S-100β protein as a biomarker in acute hemorrhagic stroke.

ABSTRACT

Acute hemorrhagic stroke, a subtype of acute stroke is one of the leading causes of death and disability throughout the world. At present, the diagnosis of acute hemorrhagic stroke is mainly based on Computer Tomography (CT) or Magnetic Resonance Imaging (MRI) but till now no biomarkers are routinely used in acute hemorrhagic stroke management. This article is a critical and descriptive review on the role of S100β protein as a biomarker in acute hemorrhagic stroke. Plasma S-100β level increases significantly in acute hemorrhagic stroke patients when compared to the normal subjects. Beside, the plasma S-100β can be correlated to the volume of hemorrhage in brain measured by plane CT scan. Plasma S-100β is an useful biomarker in acute hemorrhagic stroke and can be used for estimation of volume of hemorrhage in brain in acute hemorrhagic stroke patients. Thus, S-100β can be useful as an alternative to CT scan/MRI in diagnosis and in taking therapeutic decision in acute hemorrhagic stroke management.
