摘要:Introduction and objective. The aim of the study was to evaluate the differences between asthma and COPD on the basis
of the prevalence and profile of IgE-dependent sensitization to inhaled allergens, and the blood serum levels of select Th1/
Th2 cytokines.
Materials and method. 103 patients with COPD (114 patients with asthma and 121 controls) were included in the study.
A skin prick test with common inhaled allergens was performed, and serum levels of IgE were measured in all subjects.
Lymphocyte profiles were measured via the whole-blood method using fresh 10-ml blood samples treated with EDTA. The
following surface antigens were measured: CD3, CD29, CD16, CD56, CD4, CD8, and HLA-DR. The Th1/Th2 profile in blood
serum was determined using Th1/Th2 cytokine kits.
Results. IgE-dependent sensitization to environmental allergens was found in 34 (33.3%) patients with COPD, 46 (40%)
patients with asthma and in 14 (11.5%) volunteers. The odds ratio of sensitization in patients with COPD reached 0.89 (95%
CI: 0.57–1.08) and it was more frequent than in the control population with an odds ratio of 0.71 (95% CI: 0.64–0.88). The
serum concentration of IL-2 was significantly higher in patients with COPD and asthma than in controls. In the subgroup
of patients with non-allergic asthma, similar serum concentrations were observed for all analyzed cytokines, except for
IFN-gamma, which was lower in patients with COPD.
Conclusions. Both the prevalence and profile of IgE-dependent sensitization to inhaled allergens did not differ between
asthma and COPD. Both Th2 and Th1 played a role in the immunopathology of asthma and COPD.
