目的:探讨老年重症肺炎患者血清降钙素原检测的临床价值。方法:收集40例重症肺部感染患者(重症组)、40例非重症肺部感染患者(非重症组)、40例体检健康者(健康组),分别测定各组血清降钙素原、超敏C反应蛋白、白细胞计数及体温,并进行比较分析。结果:重症组的血清降钙素原浓度(5.69±7.38)ng/mL与非重症组(0.76±0.65)ng/mL及健康组(0.13±0.12)ng/mL比较差异均有统计学意义(P<0.05);而重症组的超敏C反应蛋白、白细胞计数及体温与非重症组比较差异均无统计学意义(P>0.05)。结论:血清降钙素原与老年肺部感染的严重程度密切相关,血清降钙素原可作为判断病情的指标。血清降钙素原可较好地预测老年重症肺炎患者的预后。
Objective: To investigate the clinical value of serum procalcitonin in senile patients with severe pneumonia. Methods: Forty cases of severe pulmonary infection (severe group), 40 cases of non-severe pulmonary infection (non-severe group) and 40 cases of healthy subjects (healthy group) were collected. Serum procalcitonin, Sensitive C-reactive protein, white blood cell count and body temperature, and comparative analysis. Results: Serum procalcitonin (5.69 ± 7.38) ng / mL in severe group was significantly lower than that in non-severe group (0.76 ± 0.65) ng / mL and healthy group (0.13 ± 0.12) ng / mL P <0.05). However, there were no significant differences in the high-sensitivity C-reactive protein, white blood cell count and body temperature between the severe and non-severe groups (P> 0.05). Conclusion: Serum procalcitonin is closely related to the severity of senile pulmonary infection. Serum procalcitonin may be used as an indicator of the severity of the disease. Serum procalcitonin is a good predictor of the prognosis of elderly patients with severe pneumonia.
