Abstract:
Objective:To investigate the predictive value of high-sensitive C-reactive protein (hs-CRP) for early hematoma enlargement in patients with primary intracerebral hemorrhage.Methods:Patients with intracerebral hemorrhage admitted to the Department of Neurosurgery, the First Affiliated Hospital of Zhengzhou University from January 2014 to January 2019 were enrolled retrospectively. The patients were sent to hospital within 6 h after onset, and the diagnosis of cerebral hemorrhage was confirmed by head CT. The head CT was reexamined within 24 h after the first head CT. Hematoma enlargement was defined as hematoma volume increase >6 ml or relative volume increase >33%. Multivariate logistic regression analysis was used to investigate the independent risk factors for influencing early hematoma enlargement. Receiver operating characteristic (ROC) curve was used to evaluate the predictive ability of hs-CRP for hematoma enlargement. Results:A total of 154 patients with intracerebral hemorrhage were included, including 99 males (64.3%), aged 58.7±11.1 years. The median baseline Glasgow Coma Scale score was 13. The time from onset to first CT scan was 2.92±1.35 h. The time from the first CT to the second one was 16.05±4.40 h. The baseline volume of hematoma was 21.82±11.08 ml. Among them, 27 patients (17.5%) had hematoma that broke into the ventricle, 40 (26.0%) had hematoma enlargement. The average hs-CRP level at admission in the enlarged hematoma group was significantly higher than that in the non-enlarged hematoma group (11.56±3.72 mg/L vs. 9.51±4.31 ml; t=-2.669, P=0.008). Multivariate logistic regression analysis showed that hs-CRP at admission (odds ratio [ OR] 1.123, 95% confidence interval [ CI] 1.017-1.241; P=0.022), irregular hematoma shape ( OR 4.160, 95% CI 1.714-10.098; P=0.002) and the time from onset to the first CT scan ( OR 0.510, 95% CI 0.323-0.803; P=0.004) were significantly correlated with hematoma enlargement. Pearson correlation analysis showed that hs-CRP was positively correlated with baseline hematoma volume ( r=0.237, P=0.003). ROC curve analysis showed that the area under the curve of hs-CRP predicting hematoma enlargement was 0.678 (95% CI 0.584-0.772). The optimal cut-off value was 10.55 mg/L. The sensitivity and specificity for predicting hematoma enlargement were 86.9% and 60.0%, respectively. Conclusion:For patients with hs-CRP ≥10.55 mg/L at admission, irregular hematoma shape, and the time from admission to the first CT scan <3 h, should be focused the management and be alert to the occurrence of early hematoma enlargement.
