Value of C-reactive Protein Detection in Children with Mycoplasma Pneumonia Infection

Objective: To explore the diagnostic value of C-reactive protein(CRP) in infant with mycoplasma pneumonia.Method: The serum CRP levels were measured by nephelometric immunoassay and ELISA in 98 infants with mycoplasma pneumonia(mycoplasma pneumonia group) and 67 infants with bacterial pneumonia(bacterial pneumonia group) 72 healthy children(control group).Result: Mean CRP levels of the pneumonia group and bacterial pneumonia group on admission were signifcantly increased(P0.05) and the order of the value of the two groups from high to low: bacterial pneumonia group mycoplasma pneumonia group(P0.05);After a week's treatment,the CRP levels of the two groups were signifcantly decreased comparing with the admission day,the mycoplasma pneumonia group's CRP level was the same with normal value(P0.05),however,the bacterial pneumonia group's CRP level was still higher than mycoplasma pneumonia group's and the control group's(P 0.05);Among 115 childern whose CRP level were increased in admission,68 children(59.13%) were younger than 4 years old,47 children(40.87%) were 4 years old or older than 4,and the youngest of them was only 2 months.Conclusion: The CRP level for children with mycoplasma pneumonia is slightly higher than normal value,but lower than that of bacterial pneumonia.CRP can be used as an important auxiliary index of identification of mycoplasma pneumonia or bacterial pneumonia.
