摘要:

目的 分析血清白细胞介素6(IL-6)、D-二聚体(DD)水平对高血压患者发生脑出血的预测作用。方法 选取400例高血压患者,随访5年,按是否发生脑出血分为发生脑出血组、未发生脑出血组,检测其血清IL-6、DD水平。采用Logistic回归分析评估高血压患者发生脑出血的危险因素;采用受试者工作特征(ROC)曲线评价各项指标预测高血压患者发生脑出血的效能。结果 400例高血压患者中,失访62例,完成随访的338例患者中,发生脑出血32例(9.47%),其中颈动脉粥样硬化占87.50%,脑微出血占25.00%;32例发生脑出血的患者血清IL-6水平为(19.02±2.51)pg/mL,血清DD水平为(318.40±57.85)μg/L,高血压病程为(12.54±2.34)年。与未发生脑出血组比较,发生脑出血组颈动脉粥样硬化、脑微出血所占比例较大(χ2值分别为15.317、5.872,P<0.001、P=0.015),血清IL-6、DD水平较高(t值分别为7.915、24.694,P<0.001),高血压病程较长(t=14.753,P<0.001)。Logisitc回归分析结果显示,颈动脉粥样硬化、脑微出血、高血压病程、IL-6、DD均是高血压患者发生脑出血的危险因素(P<0.05);血清IL-6、DD水平预测高血压患者发生脑出血的最佳临界值分别为18.35 pg/mL、287.51 μg/L,2项指标单独和联合检测预测高血压患者发生脑出血的曲线下面积分别为0.706、0.731、0.795。结论 血清IL-6、DD联合检测对高血压患者发生脑出血风险的预测价值较高,可为避免高血压患者发生脑出血提供参考。

Abstract:

Objective To study the roles of serum interleukin-6(IL-6) and D-dimer(DD) levels in predicting the risk of cerebral hemorrhage in patients with hypertension. Methods A total of 400 hypertensive patients were enrolled and followed up for 5 years. The serum IL-6 and DD levels were determined and compared between cerebral hemorrhage occurring group and non-occurring group. Logistic regression analysis was used to evaluate the risk factors for cerebral hemorrhage in patients with hypertension. Receiver operating characteristic(ROC) curve was used to evaluate the predictive roles of serum IL-6 and DD levels for cerebral hemorrhage. Results After 5 years of follow-up,62 cases of 400 hypertensive patients were lost to follow-up,and 32(9.47%) cases of cerebral hemorrhage occurred in the remaining 338 cases. The carotid atherosclerosis ratio,cerebral microhemorrhage ratio,serum IL-6 level,serum DD level and the course of hypertension were 87.50%,25.00%,(19.02±2.51) pg/mL,(318.40±57.85) μg/L and(12.54±2.34) years,respectively. Compared with non-occurring group,the carotid atherosclerosis and cerebral microhemorrhage ratios,serum IL-6 and DD levels and the course of hypertension were higher(χ2=15.317,P<0.001;χ2=5.872,P=0.015;t=7.915,P<0.001;t=24.694,P<0.001;t=14.753,P<0.001). The carotid atherosclerosis,cerebral microhemorrhage,the course of hypertension,IL-6 and DD were risk factors of cerebral hemorrhage in hypertensive patients(P<0.05). The optimal cut-off values of serum IL-6 and DD levels to predict cerebral hemorrhage in hypertensive patients were 18.35 pg/mL and 287.51 μg/L,respectively,and the areas under curves of single and combined determinations were 0.706,0.731 and 0.795,respectively. Conclusions The combined determination of serum IL-6 and DD plays a role in predicting the risk of cerebral hemorrhage in patients with hypertension,which can provide a reference for the prevention of cerebral hemorrhage.
