The aim of this study was to analyze inflammation features and possible causes of asthma-COPD overlap syndrome (ACOS). Methods. Clinical examination was performed for all patients included in the study. Blood levels of alpha-1-antitripsin (AAT), immunoglobulin (Ig) G and E antibodies against four bacterial antigens (Streptococcus pneumoniae, Haemophilus influenzae, Neisseria perflava, and Staphylococcus aureus), and lung function were measured in all the patients. Results. The study involved 175 patients including 78 patients with bronchial asthma, 39 patients with ACOS, 38 patients with COPD, and 20 healthy individuals. AAT blood level was reversely related to lung function and to increased IgG-antibody levels against bacterial antigens. Conclusion. Due to this fact, the authors suppose that the ACOS should be considered as an independent nosology distinct from asthma and COPD, and related to microbial inflammation and AAT level.
