Caspase-cleaved Cytokeratin-18 (CCCK-18) is released during apoptosis. Serum CCCK-18 concentrations are associated with prognosis of some critical illness. We investigated the potential relationships between serum CCCK-18 concentrations and disease severity and long-term clinical outcomes after intracerebral hemorrhage.
Serum CCCK-18 concentrations were determined in a total of 102 patients and 102 controls. Multivariate models were used to predict high concentration of CCCK-18 and 6-month clinical outcomes. The predictive values were evaluated based on areas under receiver operating curve.
Compared with controls, serum CCCK-18 concentrations were increased in patients (245.8±108.3U/l vs. 23.6±18.1U/l, P<0.001). National Institute of Health Stroke Scale scores [odds ratio (OR), 1.164; 95% confidence interval (CI), 1.027-1.320; P=0.003] and hematoma volumes (OR, 1.079; 95% CI, 1.018-1.205; P=0.008) were independent predictors of high concentration of CCCK-18. CCCK-18 was identified as an independent predictor of 6-month mortality (OR, 1.019; 95% CI, 1.010-1.038; P=0.013) and 6-month unfavorable outcome (OR, 1.017; 95% CI, 1.008-1.029; P=0.032) and possessed high predictive values.
Increased serum CCCK-18 concentrations are associated with disease severity and clinical outcomes, suggesting that CCCK represent a novel prognostic predictive biomarker after intracerebral hemorrhage.
半胱天冬酶切割的细胞角蛋白-18（CCCK-18）在细胞凋亡过程中释放。血清CCCK-18浓度与一些危重病的预后相关。我们研究了血清CCCK-18浓度与脑出血后疾病严重程度和长期临床结局之间的潜在关系。
共测定了102例患者和102例对照的血清CCCK-18浓度。采用多变量模型预测CCCK-18的高浓度和6个月的临床结局。基于受试者工作特征曲线下面积评估预测价值。
与对照组相比，患者血清CCCK-18浓度升高（245.8±108.3U/l对23.6±18.1U/l，P<0.001）。美国国立卫生研究院卒中量表评分[比值比（OR），1.164；95%置信区间（CI），1.027-1.320；P=0.003]和血肿体积（OR，1.079；95%CI，1.018-1.205；P=0.008）是CCCK-18高浓度的独立预测因素。CCCK-18被确定为6个月死亡率（OR，1.019；95%CI，1.010-1.038；P=0.013）和6个月不良结局（OR，1.017；95%CI，1.008-1.029；P=0.032）的独立预测因素，且具有较高的预测价值。
血清CCCK-18浓度升高与疾病严重程度和临床结局相关，提示CCCK是脑出血后一种新的预后预测生物标志物。
