Background/Aims Mucus hypersecretion and altered lung functions leads to adverse clinical outcomes in chronic obstructive pulmonary disease. The aim of this study was to compare the effects of the Lung Flute and threshold positive expiratory pressure devices on sputum quantity and pulmonary functions in chronic obstructive pulmonary disease patients. Methods A total of 50 patients with chronic obstructive pulmonary disease were randomly divided into two groups. Group 1 used the Lung Flute device and group 2 used a threshold positive expiratory pressure device. Sputum quantity was measured post-intervention on a daily basis. Forced expiratory volume in the first second, forced vital capacity, and peak expiratory flow rate were evaluated on day 1 and day 6. Results The mean sputum quantity in group 1 was 11.40 ml and it was 11.04 ml in group 2. Between-group comparison demonstrated a significant improvement in forced expiratory volume in the first second for group 1 compared to group 2 (P<0.005). Conclusions The Lung Flute was found to be slightly more effective than the threshold positive expiratory pressure device for airway clearance and also had a positive effect on pulmonary functions in patients with chronic obstructive pulmonary disease.

Aim: to conduct a comparative assessment of the hypotensive effect, as well as the effect on endothelial function, oxidative stress, and pulmonary artery pressure of chlorthalidone and hydrochlorothiazide as part of combined antihypertensive therapy in patients with arterial hypertension (AH) in combination with chronic obstructive pulmonary disease (COPD).Patients and Methods: the prospective study included 66 patients divided into two groups. As the main antihypertensive therapy, group 1 was prescribed with a combination of azilsartan medoxomil 40 mg and chlortalidone 12.5 mg as a fixed combination of Edarbi® CLO. Group 2 received a free combination of azilsartan medoxomil 40 mg (Edarbi®) and hydrochlorothiazide 12.5 mg. All patients underwent 24-hour blood pressure monitoring: (ABPM), echodopplercardiography, endothelium-dependent vasodilation, lipid peroxidation (LPO), nitric oxide metabolites, and endothelin-1 levels at baseline and after 6 months of treatment. Results: target blood pressure values (<130/80 mm Hg) were achieved in 91% of patients in group 1, and 51.5% in group 2 after 1 month of the study. After 6 months of treatment, all patients in both groups reached the target BP values, but in group 2, the dose of hydrochlorothiazide had to be increased to 25 mg. According to the ABPM data, after 6 months of treatment, group 1 showed a decrease in the morning surge in SBP by 7.0±2.1% and DBP by 10±7.3%. There was also an increase in the number of patients with the daily profile of «dipper» type to 78.8%. In group 2, there was a decrease in the morning surge in SBP by 6.3±5.9% and DBP by 4.8±4.6% after 6 months of treatment. There was an increase in the number of patients with the daily profile of «dipper» type to 36.4%. After 6 months of treatment, there was more pronounced improvement in laboratory parameters of group 1 characterizing endothelial dysfunction and oxidative stress. Statistically significant results were obtained for conjugated trienes, NO2, S, Imax, and endothelin-1 when comparing groups 1 and 2.Conclusion: treatment of AH in patients with concomitant COPD in the form of a fixed combination of azilsartan medoxomil and chlorthalidone versus free combination of azilsartan medoxomil with hydrochlorothiazide has a more pronounced antihypertensive effect, positively affecting the daily BP profile, pulmonary artery pressure, endothelial function and lipid peroxidation processes after 6 months of treatment.KEYWORDS: arterial hypertension, chronic obstructive pulmonary disease, endothelial dysfunction, lipid peroxidation, azilsartan medoxomil, chlorthalidone.FOR CITATION: Grigorieva N.Yu., Samolyuk M.O., Sheshina T.V. et al.

Abstract BACKGROUNDThere is a high prevalence of cardiovascular disease (CVD) and atherosclerosis in people with chronic obstructive pulmonary disease (COPD); sharing of risk factors could not be the only cause of the association.OBJECTIVESTo verify whether coronary atherosclerosis and peripheral vascular disease are independently associated with COPD in heavy smokers. We also investigated whether inflammation and poor lung function were related with atherosclerosis findings.METHODSHeavy smokers (≥ 20 pack-years) with COPD (group 1) or normal spirometry (group 2) were recruited. Clinical, laboratory, and anthropometric data were obtained. Main interest variables were prevalence of CCS > 75th percentile (P75), and rates of ABI < 0,9 by Doppler ultrasound. CVD risk was calculated using the Framingham risk score. Serum C-reactive protein (CRP) was measured, and lung function was assessed by spirometry. Differences between groups were compared using parametric and nonparametric tests as adequate.RESULTSWere included 87 patients, 49 with COPD (group 1). The mean ± SD age was 57.2 ± 6.0 years (58.7 ± 5.1 in group 1, 55.2 ± 6.6 in group 2, p=0.006). The mean FEV 1 % was 45.8 ± 17.24 vs. 91.7 ± 15.9 in groups 1 and 2, respectively; p<0.05. The mean smoking index was 48.6 ± 25.4, higher in the COPD group (p=0.037). Stratification by Framingham score yielded a similar distribution in both groups. The frequency of patients with CCS > P75 was 55% vs. 66% in groups 1 and 2, respectively (p=0.823); ABI <9.0 ocurred in 6,3% vs 2,6%, respectivelly ( p=0.555) . CCS and ABI were not associated to FEV 1 %. CRP was inversely associated with VEF 1 ( r s= -0.419; p<0.001), but unrelated to CCS ( r s= 0.136; p=0.265) and ABI ( r s= -0.51; p=0.677).CONCLUSIONSThe studied coronary and peripheral atherosclerosis markers were similar between heavy smokers with COPD and those with normal spirometry. Nor serum CRP neither poor lung function related to CCS or ABI. Our results suggest absence of a independent association between COPD and atherosclerosis.

ABSTRACT Introduction: Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by incomplete reversibility of airflow obstruction and persistent respiratory symptoms. Objective: To explore the therapeutic effect of physical exercise on patients with chronic obstructive pulmonary disease in pulmonary rehabilitation. Methods: Forty-eight experimental subjects were divided into control group, experimental group 1, and experimental group 2 for research. The control group received normal medical-related treatment without any other means of intervention. In addition to normal medical-related treatment, experimental group 1 received breathing training and educational interventions and experimental group 2 received exercise, breathing training and educational interventions. Results: The vital capacity of female subjects before and during the experiment ranged from 2.23±0.01 to 2.26±0.04, the FVC ranged from 2.00±0.02 to 2.01±0.03, the FEV1 ranged from 1.03±0.01 to 1.03±0.01,the FEV1% ranged from 55.50±1.29 to 55.25±1.71,the FEV1/FVC ranged from 51.44±0.24 to 50.84±1.00, andthe heart rate ranges from 65.00±0.82 to 65.50±1.29. Conclusions: Exercise training can increase the exercise tolerance of patients with COPD, relieve dyspnea, and improve the quality of life. Level of evidence II; Therapeutic studies - investigation of treatment results.

Summary Background Mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have all been investigated as novel inflammatory markers of cardiac and oncological diseases, while there is only a limited number of studies investigating these markers in chronic obstructive pulmonary disease (COPD). In the present study we examine NLR, PLR; and other markers, such as eosinophil, MPV, plateletcrit (PCT), platelet distribution width (PDW), red cell distribution width (RDW), and C-reactive protein (CRP) in patients with stable and acute exacerbation of COPD. Methods Stable COPD (Group 1, n=140), COPD with acute exacerbation (Group 2, n=110), and healthy controls (Group 3, n=50) were included in the study. Leukocyte, CRP, hemoglobin (HB), RDW, platelet, MPV, PCT, PDW, neutrophil, lymphocyte, eosinophil, NLR, and PLR were analyzed in all groups. Results HB, leukocyte, platelet, neutrophil, eosinophil, MPV, PCT, CRP, NLR, and PLR were significantly higher, while the lymphocyte was lower in Group 1 than in Group 3. Leukocyte, neutrophil, RDW, CRP, NLR, and PLR were significantly higher, while lymphocyte was lower in Group 2 than in Group 3. Leukocyte, neutrophil, RDW, CRP, NLR, and PLR were significantly higher, while HB, platelet, MPV, PCT, and lymphocyte were significantly lower in Group 2 than in Group 1. NLR and PLR increased significantly in patients with bronchiectasis when compared to those without in Group 1. Conclusions Our study results suggest that NLR, PLR and RDW can be used as simple and cost-effective markers for the evaluation of severity of exacerbation and for predicting hospitalization and further exacerbations in patients with COPD.

There were studied the possibilities of predicting the effectiveness of treatment with roflumilast in the complex therapy of patients with chronic obstructive pulmonary disease (COPD) with low and high risk by assessing the clinical and functional parameters (lung function, severity of respiratory complaints, frequency of exacerbations in the previous year) and serum indicators of systemic inflammation (C-reactive protein, TNF-α, IL-6, IL-8, fibrinogen). One-year study included 60 patients with COPD, among whom there were 22 patients with low risk (group 1) and 38 patients with high risk (group 2), according to the multi-faceted classification of disease. Each group was divided into 2 subgroups depending on the response to treatment: subgroup A included the patients whose therapy was effective and subgroup B consisted of the patients whose therapy was not effective. The criteria for the effectiveness of the treatment were: group 1 – the absence of exacerbations during a year or 1 episode that did not require hospitalization, the initial test CAT (COPD Assessment Test) – 10 points and lower, dyspnea on the mMRC scale no more than 2 points, an increase in FEV1 by 11% or more; in patients of group 2 the number of exacerbations was 0 or no more than 2 and they did not require hospitalization, dyspnea on the mMRC scale was no more than 2 points, there was no decrease in FEV1. The effectiveness of treatment was evaluated in points (4 points meant effective treatment, below 4 points – not effective treatment). It was found out that in group 1 in subgroup A after treatment the results of CAT (p<0.001), IL-8 (p<0.001), TNF-α (p<0.001) were significantly lower than in group B (p<0.001). In group 2 after treatment in subgroup A test CAT (p<0.001), CRP (p<0.001) and IL-6 (p<0.01) were significantly lower than in subgroup B. The revealed regularities formed the basis for the creation of mathematical model for predicting the effective application of roflumilast by discriminant analysis for different phenotypes of the disease which allow clinicians to solve the problem of a personalized approach to the selection of patients with COPD with low and high risk.

Background: Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by chronic airway inflammation and lung parenchyma damage. Systemic inflammation and oxidative stress also play a role in the pathogenesis of COPD. Serum albumin is a negative acute-phase protein with antioxidant effects and an important marker of malnutrition. The aim of this meta-analysis was to investigate differences in serum albumin concentrations between patients with stable COPD and non-COPD subjects. Methods: A systematic search was conducted, using the terms “albumin” and “chronic obstructive pulmonary disease” or “COPD”, in the electronic databases PubMed and Web of Science, from inception to May 2020. Results: Twenty-six studies were identified on a total of 2554 COPD patients and 2055 non-COPD controls. Pooled results showed that serum albumin concentrations were significantly lower in COPD patients (standard mean difference, SMD = −0.50, 95% CI −0.67 to −0.32; p < 0.001). No significant differences were observed in SMD of serum albumin concentrations between COPD patients with forced expiratory volume in the 1st second (FEV1) < 50% and those with FEV1 > 50%. Conclusions: Our systematic review and meta-analysis showed that serum albumin concentrations are significantly lower in patients with stable COPD compared to non-COPD controls. This supports the presence of a deficit in systemic anti-inflammatory and antioxidant defense mechanisms in COPD.

Chronic obstructive pulmonary disease (COPD) is characterized by a decline in forced expiratory volume in 1 s (FEV1) and, in many advanced patients, by arterial hypoxemia with or without hypercapnia. Spirometric and gas exchange abnormalities have not been found to relate closely, but this may reflect a narrow range of severity in patients studied. Therefore, we assessed the relationship between pulmonary gas exchange and airflow limitation in patients with COPD across the severity spectrum. Ventilation-perfusion (V̇A/Q̇) mismatch was measured using the multiple inert gas elimination technique in 150 patients from previous studies. The distribution of patients according to the GOLD stage of COPD was: 15 with stage 1; 40 with stage 2; 32 with stage 3; and 63 with stage 4. In GOLD stage 1, AaPo2 and V̇A/Q̇ mismatch were clearly abnormal; thereafter, hypoxemia, AaPo2, and V̇A/Q̇ imbalance increased, but the changes from GOLD stages 1–4 were modest. Postbronchodilator FEV1 was related to PaO2 ( r = 0.62) and PaCO2 ( r = −0.59) and to overall V̇A/Q̇ heterogeneity ( r = −0.48) ( P < 0.001 each). Pulmonary gas exchange abnormalities in COPD are related to FEV1 across the spectrum of severity. V̇A/Q̇ imbalance, predominantly perfusion heterogeneity, is disproportionately greater than airflow limitation in GOLD stage 1, suggesting that COPD initially involves the smallest airways, parenchyma, and pulmonary vessels with minimal spirometric disturbances. That progression of V̇A/Q̇ inequality with spirometric severity is modest may reflect pathogenic processes that reduce both local ventilation and blood flow in the same regions through airway and alveolar disease and capillary involvement.

OBJECTIVE AND DESIGN: To describe clinical characteristics, medication use, and low peak inspiratory flow rate (PIFR) (< 60 L/min) prevalence in nursing facility residents with chronic obstructive pulmonary disease (COPD). PATIENTS AND SETTING: Residents 60 years of age and older with a COPD diagnosis and≥ 6 months' nursing facility residence, were enrolled between December 2017 and February 2019 from 26 geographically varied United States nursing facilities. OUTCOME MEASURES: Data, extracted from residents' charts, included demographic/clinical characteristics, COPD-related medications, exacerbations and hospitalizations within the past 6 months, and functional status from the most recent Minimum Data Set. At enrollment, residents completed the modified Medical Research Council (mMRC) Dyspnea Scale and COPD Assessment Test (CAT™). Spirometry and PIFR were also assessed. RESULTS: Residents' (N = 179) mean age was 78.0 ± 10.6 years, 63.7% were female, and 57.0% had low PIFR. Most prevalent comorbidities were hypertension (79.9%), depression (49.2%), and heart failure (41.9%). The average forced expiratory volume in 1 second (FEV11) % predicted was 45.9% ± 20.9%. On the CAT, 78.2% scored≥ 10 and on the mMRC Dyspnea Scale, 74.1% scored≥ 2, indicating most residents had high COPD symptom burden. Only 49.2% were receiving a scheduled long-acting bronchodilator (LABD). Among those with low PIFR prescribed a LABD, > 80% used dry powder inhalers for medication delivery. CONCLUSION: This study highlights underutilization of scheduled LABD therapy in nursing facility residents with COPD. Low PIFR was prevalent in residents while the majority used suboptimal medication delivery devices. The findings highlight opportunities for improving management and outcomes for nursing facility residents with COPD.
