摘要
目的从D二聚体(D-dimmer)、血管性血友病因子(von Willebrand factor,v WF)、血小板(Platelet,PLT)、氨基末端B型钠尿肽前体(N terminal-pro brain natriuretic peptide,NT-Pro BNP)、白介素6(interleukin-6,IL-6)、白介素8(interleukin-8,IL-8)、肺泡表面活性蛋白D(Surfactant Protein D,SP-D)中筛选对脓毒症并发急性呼吸窘迫综合征(ARDS)具有预测价值的生物标志物。方法对48例脓毒症合并ARDS的患者和同期40例脓毒症患者进行前瞻性对照研究;在进入ICU 24 h内抽取静脉血标本,定量检测7种生物标志物的浓度/活性水平;构建脓毒症并发ARDS的风险预测模型和死亡预测模型,用Logistic回归筛选具有预测价值的生物标志物和临床指标。结果 SP-D、v WF、IL-8预测脓毒症合并ARDS的ROC曲线下面积分别为0.758(P<0.01)、0.783(P<0.01)、0.747(P<0.01);三者联合时为0.847(P<0.001);IL-8、年龄≥60岁、APACHEⅡ积分≥20对脓毒症合并ARDS具有死亡预测价值,OR值分别为12.138(ln IL-8)(P=0.022)、6.157(P=0.040)、7.415(P=0.014)。结论SP-D、v WF、IL-8对脓毒症合并ARDS具有早期预测价值,三者联合可以提高预测准确度;IL-8对脓毒症合并ARDS具有死亡预测价值,建议在临床实践中结合APACHE II评分、年龄综合评估。
Objective To select valuable biomarkers for diagnosis and predicting outcome of sepsis-related acute respiratory distress syndrome（ ARDS） from D-dimmer（ DD）,von Willebrand factor（ v WF）,platelet（ PLT）,N terminal-pro brain natriuretic peptide（ NT-Pro BNP）,interleukin-6（ IL-6）,interleukin-8（ IL-8） and surfactant protein D（ SP-D）. Methods A total of 48 sepsis accompanied with ARDS patients and 40 sepsis patients were prospectively studied with comparison. The clinical characteristics of all the patients were recorded in detail. The blood samples were obtained within 24 hours of ICU admission. The concentration or activity of the seven biomarkers was quantitatively assayed and the results were recorded. To select the most valuable biomarkers as clinical indices,diagnosis model and death predictive model were constructed by Logistic regression. Results Among the seven candidate biomarkers,SP-D,v WF and IL-8 showed the most value. Their area under the receiver operator characteristic curve（ ROC） were 0. 758（ P〈0. 01）,0. 783（ P〈0. 01） and 0. 747（ P〈0. 01） respectively,and raised to 0. 847（ P〈0. 001） when the three biomarkers were combined. IL-8,age greater than or equal to 60 years and APACHE Ⅱ score greater than or equal to 20 were related to ARDS death with12. 138（ ln IL-8）（ P = 0. 022）,6. 157（ P = 0. 040） and 7. 415（ P = 0. 014） of OR values respectively. Conclusion SP-D,v WF,IL-8should be valuable for early prediction of sepsis-induced ARDS and the diagnostic accuracy raised through combined utilization. IL-8may be predictable for prognosis of sepsis related ARDS and the comprehensive evaluation combining clinical indices with IL-8 should be suggested in clinical practice.
