    • The invention relates to the use of a certain subset of cytokine markers as prognostic variables of infection status in an individual, and especially as prognostic markers of a patients developing severe infection such as pneumonia, and respiratory tract infection following surgery. The subset of cytokine markers consists of the interleukin cytokines IL-2, IL-7, IL-23, IL-27, and IL-IO, and Interferon-? (INF?) and Tissue Necrosis Factor-a (TNFa). The markers may be employed as individual prognostic variables of infection status, or they may be used in pairs or other combinations. Generally, the abundance of the markers is correlated with infection status by means of an absolute pre-operative value of biomarker abundance, ratio's of pre-operative to post-operative biomarker abundance, or ratio values for pairs of certain biomarkers within the subset. Typically, cytokine abundance is expressed in terms of mRNA copy number wherein the copy numbers are ideally normalised to a house keeping gene and quantification of mRNA copy number is determined by RT-PCR containing reference serial dilutions of cytokine specific cDNA.
    • 本发明涉及某些亚细胞因子标记物在个体中作为感染状态的预后变量的用途,特别是作为手术后发生严重感染如肺炎和呼吸道感染的患者的预后标志物。 细胞因子标志物的亚组由IL-2,IL-7,IL-23,IL-27和IL-10以及干扰素 (INF?)和组织坏死因子-α(TNFa)。 标记物可以用作感染状态的个体预后变量,或者它们可以成对使用或其它组合使用。 通常,标记物的丰度与生物标志物丰度的绝对术前价值,手术前与术后生物标志物丰度的比值或子集内特定生物标志物对的比值相关联于感染状态。 通常,细胞因子丰度以mRNA拷贝数表示,其中拷贝数理想地归一化为保存基因,并且通过含有细胞因子特异性cDNA的参考连续稀释度的RT-PCR测定mRNA拷贝数的定量。
