Prognostic Significance Of Serum Translocator Protein In Patients With Spontaneous Intracerebral Hematoma:Preliminary Findings
NEUROLOGICAL RESEARCH(2021)
摘要
Background: The aim of this study was to measure the level of translocator protein (TSPO) in patients with intracerebral hematoma (ICH) and to determine whether TSPO can predict ICH outcomes.Method: Patients with ICH were recruited at Wujin Hospital Affiliated with Jiangsu University between January 2018 and May 2020. The level of TSPO and inflammatory factors were analyzed by enzyme-linked immunosorbent assay (ELISA). A receiver operating characteristic curve (ROC) analysis was applied to assess the accuracy of TSPO for predicting patient outcomes.Result: The median of TSPO was 2.26 ng/ml. The lower- (46 cases) and higher-(51 cases) TSPO groups were thus divided based on the median value. The perihematomal edema (PHE) volume in the lower TSPO group was 6.3 +/- 1.3 ml which was significantly lower than that in higher-TSPO group (14.8 +/- 3.5 ml) (p < 0.05). The serum level of the interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and C-reactive protein (CRP) in the higher-TSPO group was significantly higher than that in the lower TSPO group (p < 0.05). The Spearman's correlation found that TSPO concentrations significantly correlated with PHE volume, modified Rankin Scale score (MRS), IL-1 beta, IL-6, TNF-alpha, and CRP concentrations. The area under the ROC (AUC), specificity, sensitivity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and Diagnostic Odds Ratio (DOR) of TSPO was 0.932, 82.1%, 89.9%, 5.02, 0.12, and 40.8, respectively, which was more reliable than other inflammatory factors.Conclusion: The TSPO may a reliable biomarker in predicting the prognosis of ICH patients.
