Abstract:Objective To investigate the diagnostic value of C-reactive protein(CRP)and procalcitonin(PCT)in pediatric infectious diseases.Methods From September 2014 to December 2016,200 cases of infectious diseases admitted to our hospital were selected,including 100 cases of bacterial infection(bacterial infection group),100 cases of virus infection(virus infection group)and 100 cases Health staff(health group).Serum levels of CRP and PCT were measured by immunoturbidimetry.The positive rates of CRP and PCT in each group were analyzed and compared,and the diagnostic value of CRP and PCT in pediatric infectious diseases was evaluated by drawing the working curve of the subjects.Results The CRP and PCT levels in bacterial infection group were higher than those in virus infection group and healthy group(P<0.05).CRP and PCT levels in virus infection group and healthy group were similar,with no difference(P>0.05).The positive rate of CRP in bacterial infection group was higher than that in healthy group,and the positive rate of PCT was higher than that in virus infection group and healthy group (P<0.05).The CRP positive rate and PCT positive rate of healthy subjects were similar,with no significant difference (P>0.05).ROC curve analysis showed that the sensitivity of bacterial infection was 100.00%and the specificity was 94.66%when the critical value of PCT was 0.83 μg/L.The sensitivity and specificity of diagnosing virus infection were 98.93%and 93.14%.The sensitivity of diagnosis of bacterial infection was 94.97%and specificity was 87.43%when the critical value of CRP was 46.4 μg/L.The sensitivity and specificity of diagnosis of viral infection was 84.98%and 79.62%respectively;The diagnosis of bacterial infection by CRP ROC AUC was 0.842(95%CI=0.754-0.929),ROC AUC was 0.800(95%CI=0.701-0.899)for diagnosis of viral infection,and ROC AUC for PCT diagnosis of bacterial infection was 0.668 (95%CI=0.548-0.889),ROC AUC for diagnosing viral infection was 0.729 (95%CI=0.614-0.845).Conclusion CRP and PCT can be used for clinical diagnosis of routine indicators of pediatric bacterial infections,but the value of the application of pediatric viral infections is not high,and it needs to be combined with other indicators for diagnosis.
