•Serum annexin A1 levels are decreased substantially after aneurysmal subarachnoid hemorrhage.•Serum annexin A1 levels are closely correlated with severity of aneurysmal subarachnoid hemorrhage.•Serum annexin A1 appears as an independent predictor for a 6-month poor outcome after aneurysmal subarachnoid hemorrhage.•Serum annexin A1 levels efficiently predict a 6-month poor outcome after aneurysmal subarachnoid hemorrhage. Annexin A1 might be neuroprotective and serum annexin A1 concentrations were markedly declined after severe traumatic brain injury. We determine dthe ability of serum annexin A1 to assess severity and predict prognosis after aneurysmal subarachnoid hemorrhage (aSAH). We included 157 aSAH patients and 157 healthy subjects. Serum annexin A1 measurements were measured. A poor outcome was designated as Glasgow outcome scale score of 1–3. Multivariate logistic regression analysis was applied to identify predictors of a poor 6-month outcome. Serum annexin A1 concentrations were significantly lower in patients than in controls. Annexin A1 concentrations were strongly correlated with the World Federation of Neurological Surgeons scale (WFNS) score, Hunt-Hess score, Glasgow coma scale score and modified Fisher score. A total of 59 patients (37.6%) experienced a poor outcome. Serum annexin A1, WFNS score and modified Fisher score emerged as the 3 independent predictors for a poor outcome after aSAH. Under ROC curve analysis, serum annexin A1 had a fair accuracy to predict a poor outcome, AUC of serum annexin A1 concentration was equivalent to those of WFNS score and modified Fisher score and AUC of combination of the 3 factors significantly exceeded that of each one alone. Annexin A1 may be involved in the occurrence and progression of secondary brain injury after aSAH. Detection of serum annexin A1 may have certain ability for assessment of severity and prediction of long-term prognosis following aSAH.
