ABSTRACT Detection of infection-related biomarkers can assist physicians to diagnose disease, so it plays an important role in determining infection type and patients prognosis and guiding the use of antibacterial agents. Recently, Expert Consensus on Clinical Significance Interpretation of Infection-related Biomarkers was issued by Infectious Disease Professional Committee of Chinese Medical Education Association, in which the important infection-related biomarkers were introduced objectively and comprehensively. The contents related to the detection and application of procalcitonin in this expert consensus were further interpreted in this article.
KEY WORDS procalcitonin; infectious disease; detection methods
感染是临床上的常见病和多发病,可发生于人体任一部位,可能会导致患者多个器官的炎症和并发症如肺炎、脓毒症等,严重的感染甚至会危及生命。大多数感染只要诊断准确、治疗恰当都可在相对较短的时间内治愈,但有些感染仅凭症状、体征和影像学表现无法作出准确的诊断,这时就需要进行实验室检测相关指标值来辅助诊断、判断病情严重程度,以免发生误诊。基于此,2017年中国医药教育协会感染疾病专业委员会发布了《感染相关生物标志物临床意义解读专家共识》(以下简称共识)[1]。该共识系统、客观、全面地向临床医生介绍了常用和即将在临床推广应用的与感染相关的重要生物标志物,发布后得到国内专家的一致认可和好评。
目前,生物标志物已成为临床上鉴别感染、判断病情严重程度和患者预后的常用工具,如炎性反应细胞类的白细胞、炎性反应介质类的白介素-6和白介素-8、炎性反应蛋白类的C-反应蛋白和降钙素原等。……
