摘要 目的观察比较不同预后的重症肺炎患者住院期间血清和肺泡灌洗液Toll样受体4(TLR4)水平、外周血免疫细胞计数[CD3^+ T、CD4^+ T、CD8^+ T、CD19+%、T淋巴细胞+B淋巴细胞+NK细胞计数(T+B+NK计数)]。方法内科ICU住院治疗的重症肺炎患者43例,根据住院28 d内的转归(存活或死亡)将患者分为生存组25例、死亡组18例。分别于入院第1、7天采用ELISA法检测血清及肺泡灌洗液中的TLR4,采用流式细胞仪检测外周血CD3^+ T、CD4^+ T、CD8^+ T、T+B+NK计数、CD19+%。结果死亡组入院第7天血清、肺泡灌洗液中TLR4水平高于生存组(P均<0.05)。死亡组入院第1天CD19+%高于生存组,入院第7天CD3^+ T、CD4^+ T、CD8^+ T计数及CD19+%低于生存组(P均<0.05)。结论入院28 d内死亡的重症肺炎患者较生存患者TLR4水平升高,CD3^+ T、CD4^+ T、CD8^+ T计数及CD19+%下降;TLR4水平升高和免疫功能下降的重症肺炎患者预后不良。
