PCT、hs-CRP、SAA对细菌与病毒感染的鉴别作用

The roles of PCT,hs-CRP and SAA in the discrimination of bacterial and viral infections

目的探讨降钙素原(PCT)、超敏C-反应蛋白(hs-CRP)及血清淀粉样蛋白A(SAA)对病毒感染与细菌感染的鉴别作用。方法分别测定病毒感染组、细菌感染组、真菌感染组、混合感染组及非感染组患者的PCT、hs-CRP和SAA浓度,分析PCT、hs-CRP和SAA对病毒感染和细菌感染的诊断效能。结果细菌感染组、病毒感染组、真菌感染组、混合感染组及非感染组间比较,PCT、hs-CRP和SAA差异均有统计学意义(P<0.05)。PCT用于细菌与病毒感染的鉴别诊断效能最大。结论血清PCT、hs-CRP和SAA检测可用于细菌感染性疾病的诊断及其与病毒感染性疾病的鉴别。

Objective To explore the effects of PCT,hs-CRP and SAA on the discrimination of bacterial and viral infections.Methods The concentrations of PCT,hs-CRP and SAA in viral infection group,bacterial infection group,fungal infection group,mixed infection group and non-infection group were detected respectively.The diagnostic efficiency of PCT,hs-CRP and SAA for the differential diagnosis of bacterial and viral infections were analyzed.Results Among viral infection group,bacterial infection group,fungal infection group,mixed infection group and non-infection group,there were significant differences in the concentrations of PCT,hs-CRP and SAA（P〈0.05）.PCT worked at the maximum efficiency for the differential diagnosis of bacterial and viral infections.Conclusion The detection of serum PCT,hs-CRP and SAA can be used for the diagnosis of bacterial infections and the differential diagnosis with other infections.
