小儿肺炎中PCT、WBC、hs-CRP检测对疾病诊断及预后判断价值分析

目的 分析小儿肺炎中PCT、WBC、hs-CRP检测对疾病诊断及预后的判断价值.方法 选取2015年5月至2016年4月在本院住院治疗的肺炎患儿120例作为观察组,健康儿童65例作为对照组.检测治疗前后患儿及健康儿童血清PCT、WBC、hs-CRP的变化.结果 治疗前,细菌感染组WBC数量(15.5±3.4)×109/L、hs-CRP水平(19.8±2.6) mg/L和PCT水平(21.9±2.1)ng/mL均明显高于非细菌感染组(6.8 ±2.3)×109/L、(4.5±2.3)mg/L、(4.7±1.8) ng/mL和健康对照组(8.1 ±1.4)×109/L、(3.5±1.2) mg/L、(1.8±0.5) ng/mL,且差异具有统计学意义(P＜0.05).而非细菌感染组和健康对照组的WBC、hs-CRP和PCT结果差异无统计学意义(P＞0.05);治疗后,细菌感染组WBC数量(7.3±1.4)×109/L、hs-CRP水平(5.1 ± 1.2) mg/L和PCT水平(2.3 ± 1.2) ng/mL均明显低于治疗前,差异具有统计学意义(P＜0.05);WBC、hs-CRP、PCT联合检测的灵敏性95.2％、特异性93.0％、准确度93.3％显著高于WBC、hs-CRP、PCT单独检测,差异具有统计学意义(P＜0.05).结论 在小儿肺炎治疗过程中,动态监测患儿血清的WBC、hs-CRP、PCT的变化,并结合临床,有助于诊疗和判断患儿疾病愈后的情况,具有显著的临床意义,值得推广应用.

The Value of PCT,WBC and hs-CRP Tests in the Diagnosis and Prognosis of Children with Pneumonia

Objective To estimate the value of PCT,WBC and hs-CRP tests in the diagnosis and prognosis of children with pneumonia.Methods 120 cases with pneumonia in children were selected from May 2015 to April 2016 in our hospital as the observation group,65 cases of healthy children as the control group.Changes of serum PCT,WBC and hs-CRP tests in children and healthy children before and after treatment were mearued.Results Before treatment,bacterial infection group have WBC count (15.5 ± 3.4) × 109/L,hs-CRP levels (19.8±2.6) mg/L and PCT level (21.9 ±2.1) ng/mL,which were significantly higher than those in non bacterial infection group (6.8 ±2.3) × 109/L,(4.5 ±2.3) mg/L,(4.7 ± 1.8) ng/mL and healthy control group (+ 8.1 ± 1.4) × 109/L,(3.5 ± 1.2 mg/L),(1.8 ± 0.5) ng/mL (P ＜ 0.05).On the other hand,compare non bacterial infection group and healthy control group,WBC,CRP and PCT results showed no statistical significance (P ＞ 0.05).After the treatment,the bacterial infection group have WBC count (7.3 ±1.4) × 109/L,hs CRP level (5.1 ±1.2)mg/L and PCT levels (2.3 ±1.2) ng/mL,which is significantly lower than pre-treatment (P ＜ 0.05).Joint tests of white blood cell (WBC),hs CRP,PCT detection has sensitivity 95.2％,specificity of 93.0％,accuracy of 93.3％,which was significantly higher than single test of WBC,hs CRP,or PCT,(P ＜ 0.05).Conclusion In the treatment of pediatric pneumonia,the dynamic monitoring of serum WBC,hs CRP,PCT,and combined with the clinical information,is helpful for diagnosis and prognosis It is worthof applying in large population.
