title: [Incidence, pathomorphism and outcomes of the bronchopulmonary dysplasia associated with microaspiration of gastric contents].
abstract: Today the influence of the digestive tract functional violations followed by microaspiration of gastric contents (MAGC) on the incidence, features and outcomes of bronchopulmonary dysplasia BPD) remains little studied. Focusing on this aspect makes the research actual.
  
  
  OBJECTIVE
  determination of the nature of influence of MAGC on the progress and course of BPD.
  
  
  METHODS
  373 newborns exposed to artificial pulmonary ventilation (APV) in the neonatal period were examined. In a tracheobronchial aspirate (TBA) the marker of MAGC-pepsin--was determined. Its activity was measured by extinction value with subsequent analysis of the incidence and nature of the course of bronchopulmonary dysplasia (BPD) in patients against MAGC and without it. During the three years follow-up period outcomes of BPD and features of combined pathology were established.
  
  
  RESULTS
  it was revealed that in children suffered from MAGC the incidence of BPD was higher and grew in proportion to the increase of pepsin activity in TBA and the reduction of gestational age. The extinction increase in TBA values was followed by the increase in duration of APV and the subsequent oxygen therapy, and also the severity of BPD clinical course. By the end of 3 years clinical recovery was detected in 55.2% of children suffering from BPD without MAGC whereas in patients with BPD against MAGC this outcome occured only in 0.9% of cases.
  
  
  CONCLUSIONS
  MAGC is clinically significant for the etiology, pathogenesis and pathomorphism of BPD. The proposed method of early detection of MAGC and algorithm of complex therapy can reduce its severity and improve the forecast accuracy of neonatal adaptation.
