目的探讨血清降钙素原(PCT)对老年社区获得性肺炎的临床应用价值。方法对68例老年社区获得性肺炎(CAP)患者作为治疗组进行回顾性分析,以同期在宣武医院健康门诊体检的50例老年人为对照组,分别记录肺炎组患者治疗前、治疗第4天、治疗第10天的血清降钙素原(PCT)、前白蛋白、白蛋白、白细胞计数、中性粒细胞百分比、痰培养的情况,进行统计分析。结果肺炎组患者PCT浓度[(12.2±3.9)ng/ml]显著高于对照组[(0.21±0.15)ng/ml](P<0.05),有效治疗后显著降低(P<0.05)。结论 PCT可作为诊断肺部感染和观察治疗效果的敏感指标。
Objective To investigate the clinical value of serum procalcitonin (PCT) in senile community-acquired pneumonia. Methods Sixty-eight elderly patients with community-acquired pneumonia (CAP) were retrospectively analyzed. Fifty elderly patients in the health clinics of Xuanwu Hospital during the same period were selected as the control group. The patients in the pneumonia group before treatment, the fourth day of treatment, Serum procalcitonin (PCT), prealbumin, albumin, white blood cell count, neutrophil percentage, and sputum cultures on the 10th day of treatment were analyzed statistically. Results The PCT concentration in patients with pneumonia was significantly higher than that in the control group [(12.2 ± 3.9) ng / ml [(0.21 ± 0.15) ng / ml] (P <0.05). Conclusion PCT can be used as a sensitive indicator to diagnose pulmonary infection and observe the therapeutic effect.
