Application analysis of serum procalcitonin and C-reactive protein detection in the treatment of elderly pneumonia patients
血清降钙素原和C反应蛋白检测在老年肺炎患者治疗中的应用分析

摘要

目的 探讨血清降钙素原（PCT）与C反应蛋白（CRP）检测在老年肺炎患者临床治疗中的应用价值。方法 选取2024年12月-2025年12月我院收治的60例老年肺炎患者为研究组，同期60例健康老年体检者为对照组，检测两组即刻血清PCT、CRP水平，比较研究组与对照组血清PCT、CRP水平对比与不同病情严重程度老年肺炎患者血清PCT、CRP水平对比。结果 研究组即刻血清PCT、CRP水平高于对照组；老年肺炎重度组血清PCT、CRP水平高于中度组与轻度组；中度组高于轻度组（P<0.05）。结论 血清PCT、CRP可有效评估老年肺炎病情严重程度，直观反映临床治疗效果，为治疗方案调整提供客观依据，二者联合检测能提升诊断与疗效判断准确性，具有临床应用价值。

Abstract

Objective To explore the clinical value of serum procalcitonin (PCT) and C-reactive protein (CRP) detection in the treatment of elderly pneumonia patients.
Methods Sixty elderly pneumonia patients admitted to our hospital from December 2024 to December 2025 were selected as the study group, and 60 healthy elderly examinees were selected as the control group during the same period. The immediate serum PCT and CRP levels were measured in both groups, and the serum PCT and CRP levels were compared between the study group and the control group, as well as between elderly pneumonia patients with different degrees of disease severity.
Results The levels of PCT and CRP in the study group were higher than those in the control group immediately; The serum PCT and CRP levels in the severe group of elderly pneumonia were higher than those in the moderate and mild groups; The moderate group was higher than the mild group (P<0.05).
Conclusion   Serum PCT and CRP can effectively evaluate the severity of elderly pneumonia, intuitively reflect the clinical treatment effect, and provide objective basis for adjusting treatment plans. The combined detection of the two can improve the accuracy of diagnosis and efficacy judgment, and has clinical application value.
