脓毒症是一种临床综合征,其定义为表明全身炎症的生理变化,这可能归因于已记录或疑似的感染。感染性休克是指这些生理变化进展到组织中氧气和代谢底物的输送受到损害的程度。生物标志物有潜力诊断、监测、分层和预测这些综合征的结果。 C反应蛋白在炎症和感染性疾病中升高,长期以来被用作指示感染的生物标志物。最近,降钙素原被证明可以更好地区分感染和炎症。较新的候选感染生物标志物包括 IL-18 和 CD64。乳酸有助于感染性休克的诊断及其进展的监测。基于全基因组表达谱的多重分层生物标志物正在积极研究中,并呈现出令人兴奋的未来可能性。
Sepsis is a clinical syndrome defined by physiologic changes indicative of systemic inflammation, which are likely attributable to documented or suspected infection. Septic shock is the progression of those physiologic changes to the extent that delivery of oxygen and metabolic substrate to tissues is compromised. Biomarkers have the potential to diagnose, monitor, stratify and predict outcome in these syndromes. C-reactive protein is elevated in inflammatory and infectious conditions and has long been used as a biomarker indicating infection. Procalcitonin has more recently been shown to better distinguish infection from inflammation. Newer candidate biomarkers for infection include IL-18 and CD64. Lactate facilitates the diagnosis of septic shock and the monitoring of its progression. Multiple stratification biomarkers based on genome-wide expression profiling are under active investigation and present exciting future possibilities.
