Abstract

The aim of the work was to study the relationship between indicators of proteinaseinhibitory system, oxidative stress and endotoxicosis in patients with COPD. 67 patients with COPD, men with an average age of 53.12.2 years, with the duration of the disease on average 12.51.7 years, in the stable phase of the pathological process with II-IV degrees of ventilation disorders according to the GOLD were examined. The activation of trypsin as an indicator of the state of the proteinase-inhibitory system involved in bronchopulmonary diseases pathogenesis, a probable decrease in the activity of its obligate α1-antitrypsin inhibitor, lipid peroxidation secondary metabolites accumulation, total antioxidant activity, molecules of average weight level increase in serum of COPD patients were found. At the examined patients endotoxicosis with initiation of disturbances of mechanisms of recovery in bronchopulmonary system is noted. Together, these events lead to a vicious circle of persistent inflammation, accompanied by chronic oxidative stress and the process persistence. In our opinion, further studies should focus on identifying the molecular mechanisms determining the heterogeneity of COPD progression, since it is known that in some patients the disease can progress rapidly, while other patients may remain relatively stable for many years.
