Research was conducted in order to determine clinical and radiologic peculiarities, to assess the severity of lesions in small bronchi and interstitial tissue, inflammatory characteristics, and long-term outcomes of the disease.Materials. 143 children were examined. 76.7% were born with extremely low weight. Morphology study was performed in 10 children with BPD; inflammatory characteristics were assessed in 24 children. Cytokine profile and GITR were determined in children under 3 yrs. CT of the lungs was performed to 52 children under 17 yrs; 64 children underwent a complex examination of respiratory function.Results. Cytomorphology study of bronchial lavages revealed evidence of inflammation manifested in neutrophiles and lymphocytes with flat epithelial metaplasia. Percentage of CD3 was significantly decreased in the exacerbation phase (48,6±0,7) and considerably increased in the remission phase (55,2±0,6). Concentration of Il4 in the exacerbation period exceeded the upper limit of norm by 1.5 times (21,0±0,6), which then normalized and entered the remission stage. In catamnesis, only 1/3 of children had normal values for respiratory function. Obstructive changes were found in 66%, residual lung volume was increased in 49%, restrictive changes did not exceed 6% of cases.Conclusion: clinical course of BPD has been similar to the new BPD in recent years; catamnesis has evidence of bronchial hyperreactivity with minimal organic changes in the lungs.
