A TYPICAL PNEUMONIA IN CHILDREN UP TO 6 YEARS OF AGE
Journal Title: Przegląd Pediatryczny - Year 2011, Vol 41, Issue 1
Abstract
Introduction: In recent years etiological factors of pneumonia in children are changing. More and more often atypical pathogens such as Mycoplasma pneumoniae and Chlamydophila pneumoniae are involved in pathogenesis of pneumonia, both in older and the youngest children. Aim of the study was comparative analysis clinical picture of pneumonia caused by Mycoplasma pneumoniae and Chlamydophila pneumoniae in children below 6 years of age. Material and methods: The study involved 269 children hospitalized due to pneumonia caused by Mycoplasma pneumoniae and/or Chlamydophila pneumoniae. For comparative analysis, 6 groups were selected according to patients’ age and etiology of infection.Results: Over 2003-2009 period there were 1710 children, up to 6 years of age, hospitalized due to pneumonia in the 3rd Department of Paediatric, Polish Mother’s Memorial Hospital – Research Institute, of which in 269 (15.7%) the Mycoplasma pneumoniae and/or Chlamydophila pneumoniae etiology was confirmed. Mycoplasma pneumoniae, Chlamydophila pneumoniae, and mixed infection was diagnosed in 161 (9.4%), 85 (5.0%), and 23 (1.3%) children, respectively. The dominant clinical feature in all age groups was cough, observed in 85.3 to 97.1% of children, depending on etiology and patients’ age. The frequency of individual clinical features in compared groups was similar. Statistical relationship (p ≤0.05) was observed only in case of reddening of the throat in infants, which was more frequently noted in pneumonia caused by Mycoplasma pneumoniae. In analysis of basic inflammation markers, statistically significant higher WBC count was observed in infants and children 4-6 years old infected by Chlamydophila pneumoniae. In chest x-rays, no statistical relationship was observed for the described changes. Conclusions: Over recent years Mycoplasma pneumoniae and Chlamydophila pneumoniae infections are a significant problem in the young child’s care and they should be taken into consideration in differential diagnosis of pneumonia in children below 6 years of age. The clinical picture does not allow differentiation between Mycoplasma pneumoniae and Chlamydophila pneumoniae infection.
