Purpose : Mycoplasma pneumoniae pneumonia is one of the most common community- acquired pneumonias in childhood. Recently, it has tended to occur at a young age. We reviewed clinical manifestations of M. pneumoniae pneumonia in the young.
Methods : A total of 378 children who were admitted to the Bundang Jesaeng Hospital due to M. pneumoniae pneumonia from 2003 to 2006 were retrospectively analyzed. M. pneumoniae infection was confirmed by mycoplasma antibody titer >1:320 or four-fold increase of titer. The children were divided into an infant group (Group A, 0-4 years) and an older children group (Group B, 4-14 years). We analyzed the differences between the two groups according to incidence, clinical manifestations, laboratory and radiologic findings.
Results : The number of patients in Group A was 147 (38.9%) and in Group B, 231 (61.1%), respectively. Seasonal distribution showed the highest frequency in autumn and the lowest frequency in spring in both groups. The most common symptom was cough (98.6% and 96.5%, respectively) and fever (85.7% and 91.3%, respectively). The most common physical findings were crackle (72.8% and 73.3%, respectively). The common radiologic findings were lobar pneumonia in both groups (55% and 76.1%, respectively), followed by bronchopneumonia (29.2% and 11.6%, respectively). Group A had a lower incidence of high antimycoplasma antibody titer (>1:5,120) and severe pulmonary complication than Group B.
Conclusion : Group A had the more incidence of sputum production, leukocytosis, bronchopneumonia and duration of fever less than 7days. Group B had the more incidence of weak breathing sound, lobar pneumonia and duration of fever more than 7days.
