Identifying circulating biomarkers is helpful to improve outcomes. In this study, for the first time, we identify interleukin-6 (IL-6) in cerebrospinal fluid (CSF) small extracellular vesicles (sEVs) as potential biomarkers for prognosis of aSAH.Methods: We extracted small extracellular vesicles from the CSF of 103 aSAH patients and 40 healthy controls in a prospective observational study. Subsequently, we measured IL-6sEVs levels using an enzyme-linked immunosorbent assay. Results were statistically analyzed to determine the function of IL-6sEVs for disease monitoring of aSAH.Results: CSF IL-6 sEVs showed distinct pattern differences between healthy controls and aSAH patients. The concentration of IL-6sEVs in CSF is significantly correlated with the severity of aSAH patients. The areas under the receiver operating characteristic curves of IL-6sEVs for identifying severe aSAH patient from aSAH patients were 0.900. After multivariate logistic regression analysis, IL-6sEVs were associated with neurological outcome at 1 year. IL-6sEVs levels were greater and positively associated with disease processes and outcome.Conclusion: There is a neuroinflammatory cascade in aSAH patients. IL-6sEVs in CSF may be a biomarker for the progression of aSAH.Keywords: subarachnoid hemorrhage, cerebrospinal fluid, small extracellular vesicles, interleukin-6, biomarkerYao YFang XYuan JQin FYu TXia DLi ZLai NDove Medical Pressarticlesubarachnoid hemorrhagecerebrospinal fluidsmall extracellular vesiclesinterleukin-6biomarkerNeurosciences.
