    Summary. The study was aimed at investigation of regulatory T-lymphocytes (Treg) with CD4+CD25+CD127 phenotype in non-smoking and smoking patients with chronic obstructive pulmonary disease (COPD). We examined 21 non-smokers with COPD, 20 smokers with COPD, 20 healthy non-smokers, and 21 healthy smokers. T-lymphocyte subtypes were analyzed using flow cytometry. Treg percentage was significantly higher in non-smokers with COPD compared to non-smoking healthy controls. Blood Treg number in smokers with COPD was higher than in healthy smokers. Smokers with COPD had significantly higher proportion of Treg than non- smokers with COPD. We also found significant inverse correlation between Treg proportion and the CD8+ T-lymphocyte percentage in non-smoking COPD patients. The results of this study suppose a possible contribution of Treg to the systemic inflammation in COPD irrespectively of smoking.РСзюмС.

    Summary. Chronic obstructive pulmonary disease (COPD) is a difficult-to-treat progressive disease. About 14.7–68.6 % of COPD cases are not related to smoking. We examined 21 nonsmokers with COPD, 20 smokers with COPD, 20 healthy nonsmokers and 21 healthy smokers. Relative number of peripheral blood T-lymphocytes containing CCR5 and CXCR3 chemokine receptors was determined by flow cytometry. CXCR3+ and CCR5+ T-cell per cent number was increased in non-smokers with COPD compared with healthy non-smokers. A higher proportion of T-cells containing CCR5 and CXCR3 receptors on the cell surface was also observed in blood of smokers with COPD compared both to healthy smokers and nonsmokers. Our findings suggest similar mechanism of T-cells migration from blood into the airways both in non-smoking and smoking patients.РСзюмС.

    The aim of the present study was to investigate the significance of complete blood count, lymphocyte subpopulations, and cytokines in the peripheral blood in order to evaluate steroid resistance in patients with chronic obstructive pulmonary disease (COPD).Methods. Forty five patients with acute exacerbation of COPD (AECOPD) who underwent bronchoscopy the next day after hospital admission were included in the study. The patients were considered as steroid-sensitive or steroid-resistant according to the ability of dexamethasone to inhibit 50% of interleukin-8 production by alveolar macrophages. Complete blood count, lymphocyte subpopulations, cytokines, immunoglobulin E, and hormone level were measured in the peripheral blood of all patients with COPD.Results. Macrophage migration inhibitory factor (MIF) level, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were higher, and absolute and relative eosinophil numbers were lower in steroid-resistant patients with COPD compared to steroid-sensitive COPD patients. Absolute eosinophil number below the cut-off value of 0.126 Γ— 109/L was predictive for steroid resistance with the sensitivity of 83.3%, the specificity of 55.6% and the area under ROC curve (AUC) of 0.677. Relative eosinophil number below 1.2% predicted steroid resistance with sensitivity, specificity and AUC of 83.3%, 63.0%, and 0.751, respectively. NLR, PLR, and MIF higher than 2.75, 116, and 2.24 ng/mL, respectively, predicted steroid resistance with the sensitivities of 66.7%, 61.1%, and 72.2%, respectively; the specificities of 74.1%, 77.8%, and 70.4%, respectively; and the AUCs of 0.731, 0.678, and 0.740, respectively. The combination of relative eosinophil number, NLR and PLR increased the sensitivity to 83.3%, specificity to 77.8%, and AUC to 0.805. The combination of relative eosinophil number, PLR and MIF increased the sensitivity to 83.3%, specificity to 88.9%, and AUC to 0.889.Conclusion. Steroid-resistant and steroid-sensitive COPD patients differ in absolute and relative eosinophil numbers, LNR, PLR, and MIF level. These parameters could be used to predict steroid resistance in COPD.Π Π΅Π·ΠΈΡΡ‚Π΅Π½Ρ‚Π½ΠΎΡΡ‚ΡŒ ΠΊ Π³Π»ΡŽΠΊΠΎΠΊΠΎΡ€Ρ‚ΠΈΠΊΠΎΡΡ‚Π΅Ρ€ΠΎΠΈΠ΄Π°ΠΌ (Π“ΠšΠ‘) прСдставляСт ΡΡƒΡ‰Π΅ΡΡ‚Π²Π΅Π½Π½ΡƒΡŽ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΡƒ для лСчСния хроничСской обструктивной Π±ΠΎΠ»Π΅Π·Π½ΠΈ Π»Π΅Π³ΠΊΠΈΡ… (Π₯ΠžΠ‘Π›).ЦСлью настоящСй Ρ€Π°Π±ΠΎΡ‚Ρ‹ явилось ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ значСния ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»Π΅ΠΉ ΠΎΠ±Ρ‰Π΅Π³ΠΎ Π°Π½Π°Π»ΠΈΠ·Π° ΠΊΡ€ΠΎΠ²ΠΈ, субпопуляций Π»ΠΈΠΌΡ„ΠΎΡ†ΠΈΡ‚ΠΎΠ², Ρ†ΠΈΡ‚ΠΎΠΊΠΈΠ½ΠΎΠ² Π² пСрифСричСской ΠΊΡ€ΠΎΠ²ΠΈ Ρƒ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с Π₯ΠžΠ‘Π› для ΠΎΡ†Π΅Π½ΠΊΠΈ устойчивости ΠΊ Ρ‚Π΅Ρ€Π°ΠΏΠΈΠΈ Π“ΠšΠ‘.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The objective: to evaluate the ability of the combination of theophylline and budesonide to suppress proinflammatory cytokine production byblood cells in patients with chronic obstructive pulmonary disease (COPD).Subjects and Methods. Peripheral blood mononuclear cells (PBMCs) or whole blood cells of COPD patients (n = 27) were incubated with budesonide (10 nM), theophylline (1 ΞΌM), or the combination thereof and stimulated with phytohemagglutinin (PHA) or phorbol myristate acetate (PMA) and ionomycin. The enzyme immunoassay was used to evaluate the secretion of thymic stromal lymphopoietin (TSLP), macrophage migration inhibitory factor (MIF), interleukin 17A (IL-17A), IL-33, and other mediators of PBMC cells, and induced PHA. The flow cytometry was used to analyze intracellular production of proinflammatory cytokines stimulated by PMA/ionomycin in T-helpers (CD4+) and cytotoxic T-lymphocytes (CD8+).Results. Theophylline reduced the secretion of IL-4 and IL-17A by PBMC cells. The combination of budesonide with theophylline inhibited the synthesis of IL-4, IL-5, IL-8, IL-13, IL-17A, IL-33, TSLP, MIF by PBMC cells as well as the production of IL-4, IL-8, tumor necrosis factor-Ξ±, and interferon-Ξ³ by cytotoxic T-lymphocytes and T-helpers. The combination of theophylline and budesonide had a more pronounced inhibitory effect on the production of IL-4 and IL-8 by PBMC cells as well as the synthesis of IL-4 by CD4+ T-cells and IL8 by CD8+ T-lymphocytes versus the effect of monotherapy with budesonide.ЦСль исслСдования: ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ ΡΠΏΠΎΡΠΎΠ±Π½ΠΎΡΡ‚ΡŒ ΠΊΠΎΠΌΠ±ΠΈΠ½Π°Ρ†ΠΈΠΈ Ρ‚Π΅ΠΎΡ„ΠΈΠ»Π»ΠΈΠ½Π° ΠΈ будСсонида ΠΏΠΎΠ΄Π°Π²Π»ΡΡ‚ΡŒ Π²Ρ‹Ρ€Π°Π±ΠΎΡ‚ΠΊΡƒ ΠΏΡ€ΠΎΠ²ΠΎΡΠΏΠ°Π»ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… Ρ†ΠΈΡ‚ΠΎΠΊΠΈΠ½ΠΎΠ² ΠΊΠ»Π΅Ρ‚ΠΊΠ°ΠΌΠΈ ΠΊΡ€ΠΎΠ²ΠΈ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с хроничСской обструктивной болСзнью Π»Π΅Π³ΠΊΠΈΡ… (Π₯ΠžΠ‘Π›).ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    In this study the structural and surface morphological changes of Fanconi anemia patient’s fibroblasts occurring after exposure to γ–radiation were investigated by atomic force microscopy and foci immunofluorescence staining. It was found that the reorganization of the actin cytoskeleton had occurred in Fanconi anemia patient’s fibroblasts in 24 hours after irradiation, having resulted in reduction of the cell membrane stiffness and increase of adhesion in nuclear and lamellipodial regions of the cell

    Effect of azithromycin on migration of peripheral blood NK cells from patients with chronic obstructive pulmonary disease

    No full text
    Currently, no drugs have been identified that could slow progression of chronic obstructive pulmonary disease (COPD), or have a significant impact on patient mortality. Therefore, research continues aimed at studying the mechanisms of COPD development and searching for drugs that affect its molecular pathogenesis. The aim of our work was to determine the ability of azithromycin combined with corticosteroids to affect the migration of peripheral blood NK cells from the COPD patients. In the present study, we have measured expression of chemokine receptors CCR5, CCR6, CCR7, CXCR3, CXCR4, CXCR6 on the surface of peripheral blood NK cells (CD3- CD56+) by means of flow cytometry in 54 smoking patients with COPD, 21 healthy smokers, and 20 healthy non-smokers. Moreover, the effect of azithromycin (10 Β΅g/mL) and budesonide (10 nM) on the migration of NK cells from COPD patients (n = 8) towards CCL5 (10 nM) and CXCL10 (10 nM) was determined. We found that the percentage of NK cells expressing CXCR3 and CCR5 chemokine receptors was increased in smoking patients with COPD compared with healthy smokers and healthy non-smokers. However, the proportion of these NK cell subsets did not differ between healthy smokers and healthy non-smokers. There were no significant differences in the percentage of NK cells expressing CXCR4, CXCR6, CCR6, CCR7 chemokine receptors between the three groups of subjects. Addition of budesonide to the cell suspensions decreased the migration of blood NK cells towards CCL5 and CXCL10. Azithromycin was also shown to suppress the migration of blood NK cells towards these chemokines. The combination of azithromycin and budesonide was more potent at inhibiting NK cell chemotaxis towards CCL5 and CXCL10 than any of these drugs added alone. Our results demonstrate a change in the chemokine receptor profile of NK cells in COPD patients and indicate the advantages of the combined use of corticosteroids and azithromycin for COPD treatment
