Abstract:
Objective:To explore the clinical value of combined detection of procalcitonin (PCT), C-reactive protein (CRP), neutrophils (CD64), interferon-induced protein 10(IP-10) in the diagnosis of upper respiratory infectious diseases in children.Methods:A total of 122 children with upper respiratory tract infectious diseases treated in the Affiliated Hospital of Shaoxing University of Arts and Sciences from January 2017 to December 2018 were selected as the research subjects.According to the clinical symptoms and diagnosis results of the children, the children were all infected by bacteria (infected group), and healthy children in the same period were selected as normal control group ( n=61). The PCT, CRP, CD64 and IP-10 levels of the two groups were detected.The correlation between the indicators and the diagnostic value of combined detection was analyzed. Results:The PCT levels of the normal control group and infected group were (0.55±0.13)μg/L, (10.81±1.25)μg/L, respectively, and the CRP levels of the normal control group and infected group were (1.85±1.07)mg/L, (15.18±5.05)mg/L, respectively, and the CD64 index of the normal control group and infected group were (4.37±0.51), (9.91±1.62), respectively, and the IP-10 levels of the normal control group and infected group were (0.08±0.01)μg/L, (0.70±0.20)μg/L, respectively, the differences were statistically significant between the two groups( t=63.847, 20.362, 26.040, 24.163, all P<0.001). The levels of PCT, CRP, CD64 and IP-10 in the infection group were higher than those in the normal control group.After treatment, the levels of PCT, CRP, CD64 and IP-10 in the infection group were decreased (all P<0.05). Pearson correlation analysis found that PCT and CRP, PCT and CD64, PCT and IP-10, CRP and CD64, CRP and IP-10, CD64 and IP-10 were positively correlated (all P<0.05). The sensitivity, specificity and Yoden index of combined diagnosis were higher than those of single index by ROC. Conclusion:The combined detection of PCT, CRP, CD64 and IP-10 has high sensitivity and specificity.It can be used as an index for the diagnosis of early bacterial infection in children with upper respiratory infectious diseases.
