title: [Associated infections in acute bronchopulmonary infections in children].
abstract: A total of 189 children with bacterial complications of the acute respiratory viral infection (ARVI)--primarily with pneumonia and bronchitis--were dynamically examined for typical and atypical pneumotropic causative agents of the infection process (Mycoplasma pneumoniae, Chlamydia spp., Streptococcus pneumoniae, Haemophilus influenzae, Pneumocystis carini, and Citomegalovirus). A high frequency rate of the associative infection involving mycoplasmas and pneumocysts was registered (45-50%); it was lower in the cases involving Chlamydias, hemophilic bacteria, pneumococcus, and cytomegalovirus--up to 25-30%. No sharp difference was found between the indices of an infection degree and those of an active clinical infectious process involving the same pneumotropic agent: the biggest difference was observed in Chlamydia infections (9.4%) and the lowest one--in mycoplasma infections (3%). A dynamic comparison of different classes of immunoglobulins revealed that, in acute bronchitis and pneumonias, the Chlamydia and cytomegalovirus infections are, primarily, of the persistent nature; the hemophilic and pneumocystic infections are of a mixed nature; and the pneumococcus one is of the acute nature. The Mycoplasma infection, which is more often encountered in pre-school children, is of the primary type with a trend towards a prolonged clinical course. All pneumonias had a typical clinical course; the clinical picture was compared in 128 patients with the etiological factor (including a description of characteristic symptoms).
