Bioactive lipid mediators play a crucial role during infection. Previously, we showed the expression level of mRNA in septic patients was lower than in healthy controls.
Four patients with a Sequential Organ Failure Assessment (SOFA) score of <7 recovered from sepsis. One patient with SOFA score of 12 on day 7 died on day 21. In the fatal case, eicosapentaenoic acid, docosahexaenoic acid, arachidonic acid, and linoleic acid-derived lipid mediators, including 9-hydroxyoctadecadienoic acid (9-HODE), 13-HODE, 9,10-dihydroxy-12-octadecenoic acid (9,10-DiHOME), and 12,13-DiHOME, were elevated on day 1. Increase in anti-inflammatory prostaglandin E ethanolamide together with persistently lower transcription level of mRNA was detected on day 7 in the fatal case.
Lipidomic analysis on day 1 revealed elevated linoleic acid metabolites, whereas on day 7, elevated prostaglandin E ethanolamide and low level of mRNA transcription were observed in the fatal case of sepsis.
生物活性脂质介质在感染过程中起关键作用。此前,我们发现脓毒症患者中mRNA的表达水平低于健康对照者。
4例序贯器官衰竭评估(SOFA)评分<7的患者从脓毒症中康复。1例在第7天SOFA评分为12的患者于第21天死亡。在该死亡病例中,二十碳五烯酸、二十二碳六烯酸、花生四烯酸以及亚油酸衍生的脂质介质,包括9-羟基十八碳二烯酸(9-HODE)、13-HODE、9,10-二羟基-12-十八碳烯酸(9,10-DiHOME)和12,13-DiHOME,在第1天升高。在该死亡病例中,第7天检测到抗炎性前列腺素E乙醇酰胺增加以及mRNA转录水平持续降低。
脂质组学分析显示,在脓毒症死亡病例中,第1天亚油酸代谢产物升高,而第7天则观察到前列腺素E乙醇酰胺升高且mRNA转录水平较低。
