摘要
目的观察重症甲型流感肺炎患儿外周血细胞因子变化与临床意义。方法收集重症甲型流感患儿43例作为观察组,同时选取同期入住的室重症非流感病毒性肺炎患儿30例作为对照组,入院时对两组进行危重症评分,检测外周血IL-2、IL-4、IL-6、IL-8、IL-10、TNF、IFN水平。结果观察组除1例死亡,其余均病情好转后转入普通病房继续治疗,对照组无死亡病例;与对照组相比,观察组患儿血清细胞因子IL-6、IFN水平增高明显,差异均有统计学意义(均P<0.05);而IL-2、IL-4、IL-10、TNF差异均无统计学意义(均P>0.05)。结论与病毒性肺炎相比,重症甲型流感肺炎患儿血清IL-6、IL-10水平明显增高,存在免疫功能状态紊乱。
Objective To observe the changes and clinical significance of peripheral blood cytokines in children with severe influenza A pneumonia. Methods 43 children with severe influenza A admitted to PICU(observation group) and30 children with severe non-influenza virus pneumonia admitted to paediatric department(control group) were enrolled.They all were assessed with critical illness score. Peripheral blood IL-2、IL-4、IL-6、IL-8、IL-10、TNF and IFN were measured. Results Except for one death in the observation group,all patients were transferred to the general ward for continuous treatment after their condition improved. There was no death in the control group. Compared with the control group, serum levels of cytokines IL-6 and IFN were significantly increased in the observation group(P <0.05). No significant difference of IL-2, IL-4, IL-10 and TNF was found between the two groups. Conclusion There is a disorder of immune function in children with severe influenza A pneumonia.
