摘　　要：目的:探讨PCT在诊断及评估老年社区获得性肺炎(CAP)中的临床意义。方法:143例老年社区获得性肺炎患者治疗前进行痰培养,根据痰培养结果分为细菌阳性组112例和细菌阴性组31例,选取健康老人50例作为健康对照组,比较3组的PCT值。将细菌阳性者分为轻、中、重危组,比较3组的PCT值与患者严重程度的关系。结果:细菌阳性组、细菌阴性组和健康对照组的PCT值比较,差异有统计学意义(P<0.05);细菌阳性组与健康对照组、细菌阴性组与健康对照组CRP、WBC值比较,差异均有统计学意义(P<0.05);细菌阳性组与细菌阴性组、细菌阳性组与健康对照组NEU值比较,差异均有统计学意义(P<0.05)。轻危组、中危组和重危组PCT值两两比较,差异均有统计学意义(P<0.05)。结论:监测血清PCT值不仅可以作为CAP患者确诊的重要标志物,还可作为判定感染程度的依据。Objective:To explore the clinical significance of PCT in the diagnosis and evaluation of elderly community acquiredpneumonia.Methods:143 elderly patients with community acquired pneumonia were given sputum culture before treatment.According to the sputum culture results,they were divided into the bacterial positive group with 112 cases and the bacterianegative group with 31 cases.50 cases of healthy elderly people were selected as the healthy control group.The PCT values ofthree groups were compared.The bacterial positive patients were divided into the light,medium and heavy risk group.Therelationship between the PCT values of three groups and the severity of the patients was compared.Results:The PCT values of thebacterial positive group,the bacteria negative group and the healthy control group were compared,and the difference wasstatistically significant(P<0.05).The CRP、WBC values of the bacterial positive group and the healthy control group,the bacterianegative group and the healthy control group were compared,and the differences were all statistically significant(P<0.05).TheNEU values of the bacterial positive group and the bacteria negative group, the bacterial positive group and the healthy controlgroup were compared,and the differences were all statistically significant(P<0.05).The PCT values of the light risk group,themedium risk group and the heavy risk group were compared,with significant difference(P<0.05).Conclusion:Monitoring serumPCT values can not only as an important marker for the diagnosis of CAP patients,but also as a basis for the infection degree.
