Abstract:
Objective To evaluate the value of haptoglobin (HPT),α1-acid glycoprotein (AAG)and C-reactive protein (CRP) in the differential diagnosis of bacterial and viral infection in children. Methods Serum CRP, AAG and HPT levels were measured in 64 children with bacterial infection and 64 children with viral infection during acute stage. These indicators were also measured in 31 normal control children. The sensitivity ,specificity ,positive and negative predictive values, Youden's index for HPT,AAG and CRP were calculated. These values were compared among three groups. Their early diagnostic value on bacterial infection and virus infection was evaluated. Results (1) These markers were considered positive if HP≥2 g/L,AAG≥2 g/L,CRP≥10 mg/L. (2) The serum CRP [(2.70 ±0.99) g/L vs (1.42 ±0.75) g/L] ,AAG [(0.91 +0.38) g/L vs (0.30+0.08) g/L] and HPT [(6.40 ±0.89) mg/L vs (1.38 +0.80) mg/L]levels were significantly higher in children with bacterial infection compared with those with viral infection during the acute stage (P ＜ 0. 05,P ＜ 0. 01). The serum CRP, AAG and HPT levels were significantly higher in children with bacterial infection compared with normal control children during the acute stage (P ＜ 0. 05);while the levels of these indicators showed no differences between viral infection children and normal control children (P ＞ 0. 05). Conclusion The measurement of serum CRP, AAG and HPT levels has clinical value in the differential diagnosis of bacterial and viral infection in children. Among these indicators, CRP has the highest specificity,positive predictive,negative predictive values and Youden's index.
