Mycoplasma pneumonia (MP) is a major cause of community-acquired pneumonia in children and young adults. We aimed to investigate the factors that may influence on the clinical manifestations of MP in children.
A total of 109 admitted children from October 2011 to February 2012 were prospectively enrolled with physical examination and laboratory tests (complete blood count, C-reactive protein [CRP], and particle agglutinin assay). The diagnosis of MP was made when there was an infiltration on the chest X-ray and the particle agglutination test was once over 1:640 or showed 4-fold increase in serial tests. They were grouped by age, fever duration after treatment, presence of pleural effusion and wheezing.
Preschool children showed shorter duration of fever (P=0.001), more wheezing (P<0.001), lower segmented neutrophil (P<0.001), and lower CRP levels (P=0.004) compared to schoolchildren. Prolonged fever (>3 days) and pleural effusion were developed in children with higher CRP (P=0.018 and P=0.007). Wheezing has been developed in children with younger age (P=0.007).
Younger age was a risk factor to develop wheezing in MP and prolonged fever and pleural effusion were more likely to develop in children with higher CRP.
