title: [Clinical characteristics and condition of the bronchial tree in patients with bronchial asthma and chronic obstructive pulmonary disease in combination with hyperoxaluria].
abstract: OBJECTIVE
  To evaluate peculiarities of a clinical course and changes in bronchial mucosa in bronchial asthma (BA) patients with chronic obstructive pulmonary disease (COPD) in combination with hyperoxaluria (HOU); informative value of some laboratory and device findings including oxalates assay in bronchial lavage fluid for specification of the diagnosis, role of oxalates in development of obstructive syndrome and choice of optimal therapy.
  
  
  METHODS
  Oxalates were examined in daily urine, bronchoalveolar lavage fluid and exhaled air condensate of 104 patients with BA and COPD, 77 of which had HOU and an atypical course of bronchial obstruction syndrome.
  
  
  RESULTS
  Conception of airways inflammation in patients with oxalate metabolism disturbances is proposed. It is shown that insoluble oxalates participate in pathogenesis of bronchial obstruction.
  
  
  CONCLUSIONS
  Oxalate metabolism disturbances are an important factor in pathogenesis of airways inflammation and development of bronchial obstruction in predisposed patients. Therefore, administration of insoluble oxalates lowering therapy may effectively prevent formation and progression of obstructive pulmonary diseases in this group of patients.
