Abstract:
Objective To select valuable biomarkers for diagnosis and predicting outcome of sepsis-related acute respiratory distress syndrome(ARDS) from D-dimmer (DD),yon Willebrand factor (vWF),platelet (PLT),N terminal-pro brain natriuretic peptide (NT-ProBNP),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,vWF 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 with 12.138(lnIL-8)(P=0.022),6.157(P=0.040) and7.415(P=0.014) of OR values respectively.Conclusion SP-D,vWF,IL-8 should be valuable for early prediction of sepsis-induced ARDS and the diagnostic accuracy raised through combined utilization.IL-8 may be predictable for prognosis of sepsis related ARDS and the comprehensive evaluation combining clinical indices with IL-8 should be suggested in clinical practice.
