Abstract
BACKGROUND:Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) might contribute to brain inflammation after acute brain injury. The current study was designed to investigate whether serum soluble TWEAK (sTWEAK) can serve as a potential biomarker for functional outcome after aneurysmal subarachnoid hemorrhage (aSAH).
METHODS:In this single-center prospective, observational study, admission serum sTWEAK concentrations were quantified among 112 aSAH patients. Impact of serum sTWEAK concentrations on a poor outcome (Glasgow outcome scale score 1-3) at 6 months after stroke onset was determined using multivariate analysis.
RESULTS:Admission serum sTWEAK concentrations were intimately correlated with serum C-reactive protein concentrations, World Federation of Neurological Surgeons scores and modified Fisher scores. A total of 38 patients (33.9%) had a poor outcome at post-hemorrhagic 6 months. Admission serum sTWEAK concentrations were substantially higher in patients with a poor outcome than in the other remainders. Under receiver operating characteristic curve, serum sTWEAK concentrations significantly distinguished a poor outcome. Serum sTWEAK concentrations > 3.23 ng/ml discriminated the risk of a poor outcome with medium-high sensitivity and specificity and independently predicted a poor outcome.
CONCLUSIONS:Serum sTWEAK, in close correlation with inflammation and hemorrhagic severity, might represent a potential biomarker for predicting clinical outcome after aSAH.
