老年下呼吸道感染患者C反应蛋白测定的临床意义

The significance of C-RP in aged patients with lower respiratory infection

目的观察C反应蛋白测定对老年下呼吸道感染患者的诊断和治疗方面的临床价值。方法采用胶体金法测定老年下呼吸道感染患者治疗前后血C反应蛋白(CRP)浓度,并测定患者治疗前后的血沉(ESR),血白细胞总数(WBC),中性粒细胞百分数(N),体温(T),痰培养等的变化。结果患者入院时CRP均明显大于20 mg/L,治疗后的CRP水平明显降低(P<0.01),且老年下呼吸道感染患者的CRP的阳性率明显高于ESR,WBC,N,T和痰培养阳性率。结论 CRP可作为诊断老年下呼吸道感染和观察疗效的敏感指标之一。

Objective To evaluate the clinical value of the C-RP in the diagnosis and treatment of the aged patients with lower respiratory infection.Methods We detected the C-RP in colloidal gold method of the aged patients with lower respiratory infection.Also detected ESR,the total number of the white blood cells,neutrophil,temperature and sputum culture before and after treatment of change.Results The C-RP levels were more than 20 mg/L when the patients were admitted,while they decreased significantly after treatment.The positive rate of C-RP in Aged patients with lower respiratory infection was higher than WBC,neutrophil,ESR,temperature,and sputum culture（P0.01）.Conclusion C-RP can be one of the sensitive index to diagnose the aged patients with lower respiratory infection and monitor the treatment.
