血清降钙素原检测在老年细菌性肺炎诊断及严重程度评估中的价值分析

目的研究血清降钙素原(procalitonin,PCT)检测在老年细菌性肺炎诊断及严重程度评估中的价值。方法选取2018年1月至2019年6月本院收治100例老年细菌性肺炎患者、90例病毒性肺炎患者、85例支原体肺炎患者为研究对象,选取同期于本院进行体检的健康体检者100例为对照组。所有研究对象均进行PCT检测、C反应蛋白(C-reactionprotein,CRP)检测,对比不同肺炎类型、不同疾病程度研究对象的血清PCT、CRP水平及阳性率。结果老年细菌性肺炎患者的血清PCT水平、血清CRP水平明显高于病毒性肺炎组、支原体肺炎组、对照组,差异具有统计学意义(P<0.05);老年细菌性肺炎患者的血清PCT和血清CRP水平及阳性率随着病情严重程度加重而提高,差异具有统计学意义(P<0.05),老年细菌性肺炎患者的血清PCT阳性率与血清CRP阳性率比较差异无统计学意义。结论在老年细菌性肺炎中应用血清降钙素原检测的诊断价值较高,能够有效评估老年细菌性肺炎患者病情的严重程度。

The value of serum procalcitonin in diagnosing and evaluating the severity of bacterial pneumonia in the elderly

Objective To investigate the value of serum procalitonin(PCT)in the diagnosis and severity assessment of bacterial pneumonia in the elderly.Methods 100 cases of bacterial pneumonia,90 cases of viral pneumonia and 85 cases of mycoplasma pneumonia admitted to our hospital from January 2018 to June 2019 were selected as the research objects,and 100 cases of healthy people who underwent physical examination in our hospital during the same period were selected as the control group.PCT detection and C-Reactionprotein(CRP)detection were performed on all subjects to compare the serum PCT,CRP level and positive rate of the subjects with different types of pneumonia and different degrees of disease.Results The levels of serum PCT and serum CRP in elderly patients with bacterial pneumonia were significantly higher than those in viral pneumonia group,mycoplasma pneumonia group and control group,and the differences were statistically significant(P<0.05).The serum PCT and serum CRP levels and positive rates of elderly patients with bacterial pneumonia increased with the severity of the disease,and the difference was statistically significant(P<0.05).There was no statistically significant difference between the serum PCT positive rates and serum CRP positive rates of elderly patients with bacterial pneumonia.Conclusion The diagnostic value of serum procalcitonin detection in senile bacterial pneumonia is high and it can effectively evaluate the severity of the disease in senile bacterial pneumonia patients.
