The study indicates, for the first time, the changes in both ATPase and AChE activities in the membrane of red blood cells of patients diagnosed with COPD. Chronic obstructive pulmonary disease (COPD) is one of the most common and severe lung disorders. We examined the impact of COPD on redox balance and properties of the membrane of red blood cells. The study involved 30 patients with COPD and 18 healthy subjects. An increase in lipid peroxidation products and a decrease in the content of -SH groups in the membrane of red blood cells in patients with COPD were observed. Moreover, an increase in the activity of glutathione peroxidase and a decrease in superoxide dismutase, but not in catalase activity, were found as well. Significant changes in activities of erythrocyte membrane enzymes in COPD patients were also evident demonstrated by a considerably lowered ATPase activity and elevated AChE activity. Changes in the structure and function of red blood cells observed in COPD patients, together with changes in the activity of the key membrane enzymes (ATPases and AChE), can result from the imbalance of redox status of these cells due to extensive oxidative stress induced by COPD disease.

Abstract Background Diagnostic biomarkers for detecting chronic obstructive pulmonary disease (COPD) in acute coronary syndrome (ACS) patients are not available. SERPINA1, coding for the most potent circulating anti-inflammatory protein in the lung, has been found to be differentially methylated in blood cells from COPD patients. This study aimed to investigate the methylation profile of SERPINA1 in blood cells from ACS patients, with (COPD+) or without COPD (COPD−). Methods Blood samples were from 115 ACS patients, including 30 COPD+ and 85 COPD− according to lung function phenotype, obtained with spirometry. DNA treated with sodium bisulfite was PCR-amplified at SERPINA1 promoter region. Methylation analysis was carried out by sequencing the PCR products. Lymphocytes count in ACS patients was recorded at hospital admission and discharge. Results SERPINA1 was hypermethylated in 24/30 (80%) COPD+ and 48/85 (56.5%) COPD− (p < 0.05). Interestingly, at hospital discharge, lymphocytes count was higher in COPD− patients carrying SERPINA1 hypermethylated (1.98 × 103 ± 0.6 cell/µl) than in COPD− carrying SERPINA1 hypomethylated (1.7 × 103 ± 0.48 cell/µl) (p < 0.05). Conclusions SERPINA1 is hypermethylated in blood cells from COPD+ patients. COPD− carrying SERPINA1 hypermethylated and high lymphocytes count may be at risk of COPD development. Therefore, SERPINA1 hypermethylation may represent a potential biomarker for predicting COPD development in ACS patients.

Objective: to study the composition of fatty acids (FA) and mitochondrial membrane potential (MMР) of blood cells in patients with chronic bronchitis (CB) and chronic obstructive pulmonary disease (COPD); to establish the role of the Mitochondrial dysfunction in the formation of respiratory diseases. Material and methods. The study involved 26 patients with chronic bronchitis, 27 - with mild COPD, 21 - with moderate COPD steady flow, 29 healthy people. MMР leukocytes was assessed by flow cytometry. The composition of the FA mitochondrial membranes was studied by gas-liquid chromatography. Results and discussion. With the worsening of the disease (moderate COPD) increases the number of white blood cells with reduced MMP, appears deficit of the saturated, monoenic (14: 0, 16: 0, 18: 0) and n-3 polyunsaturated fatty acids (18: 3n-3 20: 5n-3, 22: 5n-3, 22: 6n-3) in the membrane of the mitochondria. Identified imbalance in the composition of fatty acids verifies the changes in the physicochemical properties of subcellular membrane malfunction membrane transport systems, enzymes and receptors, processes of oxidative phosphorylation. Conclusion: The imbalance in the composition of the LCD mitochondrial membranes lead to the development of mitochondrial dysfunction and the formation of cell hypoxia.

IntroductionBlood cells are involved in systemic inflammation in chronic obstructive pulmonary disease (COPD). We aimed to assess differences in leukocyte subsets and their ratios between COPD patients and healthy individuals as well as their association with disease severity, smoking status and therapy in COPD.Material and methodsOne hundred and nine patients in the stable phase of COPD and 95 controls participated in the study. After blood sampling, white blood cells (WBC), neutrophils (NEUTRO), monocytes (MO), lymphocytes (LY) and basophils (BA) were determined on a Sysmex XN-1000 analyser, and ratios were calculated afterwards.ResultsWhite blood cells, NEUTRO, MO and BA were higher in COPD patients than in controls. Also, COPD patients had increased neutrophil to lymphocyte ratio (NLR), derived NLR (dNLR), monocyte to lymphocyte ratio (MLR), basophil to lymphocyte ratio (BLR), basophil to monocyte ratio (BMR) and monocyte/granulocyte to lymphocyte ratio (M/GLR). Smoking has an impact on leukocyte counts, with BA, BLR and BMR being higher in COPD smokers vs. ex-smokers. Patients with very severe COPD were distinguished from moderate COPD by NLR, dNLR and M/GLR. In addition, those parameters were associated with lung function and dyspnoea, and NLR and dNLR also with multicomponent COPD indices BODCAT and DOSE. Great potential of dNLR, NLR and M/GLR in identifying COPD patients was observed regarding their odds ratios (OR) of 5.07, 2.86, 2.60, respectively (p < 0.001). Common COPD therapy did not affect any of the parameters investigated.ConclusionsLeukocyte subsets and their ratios could be implemented in COPD assessment, especially in evaluating disease severity and prediction.

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 μM), 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-α, and interferon-γ 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.
