[The condition of the proteinase-antiproteinase system in patients with type II diabetes and chronic obstructive pulmonary disease].
Chronic obstructive pulmonary disease (COPD) and type II diabetes are major worldwide health problems. Proteinase-antiproteinase system (PAS) disbalance is known to play a significant role in COPD pathogenesis. There is increasing evidence concerning proteolysis activation as a factor of vascular complications. The subjects of this study were 130 individuals aged 39 to 68 years, divided into three groups. Group I consisted of 25 patients with type II diabetes, group 2--32 patients with type II diabetes and COPD, group 3--33 COPD patients, and group 4--40 apparently healthy people. Investigation of the PAS in these subjects demonstrated an important role of the condition of PAS in the development of COPD and type II diabetes, and a possible role of a hyposecretory mutation of alpha1-proteinase inhibitor gene as a risk factor of both bronchopulmonary and endocrine pathology.
