Research Article: Serum Sestrin Emerges as a Prognostic Biomarker of Human Aneurysmal Subarachnoid Hemorrhage: A Prospective Observational Cohort Single-Center Study

Date Published: 2023-08-28

Abstract:
Aneurysmal subarachnoid hemorrhage (aSAH), which is characterized as a hemorrhagic stroke resulting from aneurysmal rupture, is the principal cause of death and disability among survivors around the world. When bleedings accumulate inside the subarachnoid space, some subsequent phenomena, such as early brain injury (EBI) and delayed cerebral ischemia (DCI), occur., Both EBI and DCI are the two key pathophysiological processes pertaining to acute brain injury following aSAH. Oxidative stress and inflammation have been acknowledged as the two main molecular mechanisms contributing to acute brain injury after aSAH., The excessive generation of reactive oxygen species and cytokines results in cellular toxicity, thereby inducing neuronal death, brain edema and blood–brain barrier disruption; and such brain damage elicited neurologic dysfunction and even death of patients with aSAH. Clinically, several severity assessment scales, such as the Hunt-Hess scale and modified Fisher scales, have been universally adopted as the prognostic predictors of aSAH. Noteworthily, biochemical markers in peripheral blood, such as glial fibrillary astrocyte protein, myelin basic protein, SB, C-reactive protein and interleukin-, are ubiquitously studied and exploration of apposite prognostic biomarkers has attracted widespread attentions in aSAH-related neurologic science during recent decades.,
