Этиологическая характеристика внебольничной пневмонии у детей в зависимости от возраста

Aim. The study was aimed at investigation of etiology of communityacquired pneumonia (CAP) in children in relation to age. Methods. Chlamydophila pneumoniae, Mycoplasma pneumoniaе, respiratory viruses, Epstein–Barr virus, cytomegalovirus and human herpes virus type 6 were searched using bacteriological, serological and molecular methods. Results . We examined 145 hospitalized children aged 1 month to 17 years with respiratory infection complicated by moderate CAP. Viruses were detected in 62 % of children under 4 years old, in 43 % of children of 4 to 7 years old and in 17 % of schoolage children. A rate of mixed viralbacterial CAP decreased with aging and was found in 30 % of children under 4 years old and in 4 % of schoolage children. Conclusion . Viral infection, mainly respiratory syncytial virus and cytomegalovirus, prevailed in the etiology of CAP in children under 4 years; C. pneumoniae and M. pneumoniae prevailed in schoolage children.
