传染性非典型肺炎患者血清细胞因子水平动态观察

Dynamic studies on the serum cytokines level of different stage in the diagnosed SARS patients

目的 研究传染性非典型肺炎又称严重急性呼吸综合征(SARS),探讨患者在不同发病阶段血清中多种细胞因子的变化、发病机理及与免疫反应的关系。方法 应用Randox公司产生的EVIDENCE180全自动化学发光生物芯片分析仪,对90名健康成年人和34例确诊SARS患者的早、中、晚3期血液标本分别进行了12项细胞因子的定量检测,以比较不同发病阶段各种细胞因子的变化趋势。结果 SARS患者血清中的细胞因子水平除IL-1β没有显著变化外,其他各项变化均比较明显。其中,IL-6、IL-8、IL-10及干扰素γ与健康人比较显著上升;而IL-1α、IL-2、IL-4、血管内皮生长因子、表皮生长因子、单核细胞趋化蛋白-1及肿瘤坏死因子α与健康对照组比较显著下降。结论 各种血清细胞因子在SARS患者不同发病时期有较大变化,发病早期尤为明显,本结果进一步支持SARS患者的病理损伤过程与免疫失调有关。

Objective To evaluate the clinical significance of the multiple cytokines in the serum of SARS patients and explore the rel ationship between the immune-reactivity and pathological damages. Methods 12 different serum cytokines have been detected in 4 groups ( inchoation, metaphase, convalescence of SARS patients and Healthy control) by using biochips technique(RANDOX) and to study the changes of each cytokine level in SARS patients. Results Compared with healthy group, IL-6 , IL-8 , IL-10 ,IFNγ increased obviously and IL-1α ,IL-2,IL-4,VEGF,EGF,MCP-1, TNFαdecreased obviously. Whereas IL-1βhas no statistic changes among different stages of SARS. Conclusion There were obvious changes of multiple cytokines in different phase of SARS pathological process, especially in the early phase. It is further support the hypothesis that over-reaction of the immune system initiated the pathological injuries of the patients.
