Background and aims. Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death worldwide, with increasing mortality and morbidity. The neutrophil to lymphocyte ratio (NLR) and blood eosinophils level (EOS) represent  biomarkers of inflammation in various diseases, with current research in the field of COPD. The aim of this study was to determine correlations of NLR and EOS with certain characteristics of COPD in a group of patients without major comorbidities. Methods. We conducted an observational study on COPD patients admitted to the Clinical Hospital of Pneumology in Cluj-Napoca, Romania. The smoking history, body mass index (BMI), NLR, EOS, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and the arterial partial pressure of oxygen (PaO2) were determined. Functional assessment consisted of spirometric and BODE index determinations. The duration of hospitalization was expressed as the length of stay (LOS). The patients were divided into 3 subgroups: active smokers (AS), former smokers (FS) and never smokers (NS). Results. No significant differences between AS and FS were found when age, airway obstruction, BODE index, PaO2, ESR and CRP were considered. The NLR was higher in AS versus FS (p=0.035), while EOS was lower in AS group (p=0.061). COPD patients with ≥300EOS/μL had lower CRP, ESR levels and NLR compared to those with eosinophilia˂300/ μL (p=0.020, p=0.009 and p=0.007, respectively). With a threshold of 3.5 for NLR, patients with lower NLR had lower CRP values (p=0.05). COPD patients with higher NLR had significant lower EOS levels (p=0.018). Overall, the NLR and EOS were not correlated with the investigated characteristics (p˃0.05), but intragroup analysis (based on smoking status) revealed correlations with ESR (p=0.0001), CRP (p=0.053), BODE index (p=0.029) and LOS (p=0.042).             Conclusions. AS have higher NLR and lower EOS lelvels versus FS. COPD patients  with higher EOS level have lower CRP, ESR and NLR. In AS, EOS level is positively correlated with BODE index and negatively correlated with NLR.

Chronic obstructive pulmonary disease (COPD) is the leading cause of death in the structure of respiratory diseases. The problem of rational pharmacotherapy of COPD have attracted attention of the medical scientific society for many years. The understanding of the pathogenesis of the disease has deepened and approaches to the therapy have changed. Some COPD patients need regular fixed-combination therapy: long-acting bronchodilators (LABD) and inhaled corticosteroids (ICS) in order to prevent exacerbations and reduce the severity of symptoms of the disease. Blood eosinophils count is one of criteria for choosing regular therapy. The appearance of fixed triple combinations of ICS/LABD increased the effectiveness of COPD therapy, and a new delivery device for fixed combination of budesonide/formoterol makes it possible to use ICS successfully in the most severe patients.

The aim of this study was to investigate morphological and functional erythrocyte parameters in smokers with chronic obstructive pulmonary disease (COPD). We measured erythrocyte parameters (RBC, HGB, HCT, MCV, MCH, MCHC, RDW-SD) using the automatic hematological analyzer Sysmex XT-2000i. Sixty-nine patients participated in the study. The patients were divided into 3 groups: 34 patients with COPD (mean age 63 yrs, median smoking history 36 packyrs); 15 smokers without bronchial obstruction (mean age 56 yrs, median smoking history 28 packyrs) and 20 nonsmokers of the sane age without bronchial obstruction. Smokers with COPD and smokers without bronchial obstruction had significantly higher erythrocyte parameters compared to those of nonsmokers. Smokers demonstrated higher HGB level that could be as a compensatory reaction to nicotine-related preclinical hypoxia. Marked increase in RBC number and anisocytosis (RDW-SD) reflected the erythron activation in smokers with COPD. These results suggest that measurement of erythrocyte parameters could be useful to assess symptomatic erythrocytosis in COPD patients.

Blood Eosinophils

Blood eosinophils measurement, as proxy for tissue eosinophils, has become an important biomarker for exacerbation risk and response to inhaled corticosteroids (ICS) in Chronic Obstructive Pulmonary Disease (COPD). Its use to determine the pharmacological approach is recommended in the latest COPD guidelines. The potential role of blood eosinophils is mainly based on data derived from post-hoc and retrospective analyses that showed an association between increased blood eosinophils and risk of exacerbations, as well as mitigation of this risk with ICS. Yet other publications, including studies in real life COPD, do not confirm these assumptions. Moreover, anti-eosinophil therapy targeting interleukin (IL)-5 failed to reduce exacerbations in COPD patients with high blood eosinophils, which casts significant doubts on the role of eosinophils in COPD. Furthermore, a reduction of eosinophils might be harmful since COPD patients with relatively high eosinophils have better pulmonary function, better life quality, less infections and longer survival. These effects are probably linked to the role of eosinophils in the immune response against pathogens. In conclusion, in COPD, high blood eosinophils are widely used as a biomarker for exacerbation risk and response to ICS. However, much is yet to be learned about the reasons for the high eosinophil counts, their variations and their controversial effects on the fate of COPD patients.

Artery Stiffness

Early stages of chronic obstructive pulmonary disease (COPD) are characterized by the loss and narrowing of terminal bronchioles in the lung, resulting in “air-trapping,” often occurring before overt emphysema manifests. Individuals with an airway-predominant phenotype of COPD display extensive lung air-trapping and are at greater cardiovascular disease (CVD) risk than COPD patients with an emphysema-predominant phenotype. We hypothesized that the degree of computed tomography (CT)-quantified lung air-trapping would be associated with greater aortic and carotid artery stiffness and lower endothelial function, known biomarkers of CVD risk. Lung air-trapping was associated with greater aortic stiffness (carotid femoral pulse wave velocity, CFPWV) ( r = 0.60, P = 0.007) and carotid β-stiffness ( r = 0.75, P = 0.0001) among adults with ( n = 10) and without ( n = 9) a clinical diagnosis of COPD and remained significant after adjusting for blood pressure (BP) and smoking history (pack-years) (carotid β-stiffness: r = 0.68, P < 0.01; CFPWV r = 0.53, P = 0.03). The association between lung air-trapping and carotid β-stiffness remained significant after additionally adjusting for age and forced expiratory volume 1(FEV1) ( r = 0.64, P = 0.01). In the COPD group only ( n = 10), lung air-trapping remained associated with carotid β-stiffness ( r = 0.82, P = 0.05) after adjustment for age, pack-years, and FEV1. In contrast, no association was observed between CFPWV and lung air-trapping after adjustment for BP, pack-years, age, and FEV1 ( r = 0.12, P = 0.83). Lung air-trapping was not associated with endothelial function (brachial artery flow-mediated dilation) in the entire cohort ( P = 0.80) or in patients with COPD only ( P = 0.71). These data suggest that carotid artery stiffness may be a mechanism explaining the link between airway-predominant phenotypes of COPD and high CVD risk. NEW & NOTEWORTHY Previous cross-sectional studies have demonstrated greater large elastic artery stiffness and lower endothelium-dependent dilation in chronic obstructive pulmonary disease (COPD) patients compared with controls. Furthermore, COPD patients with emphysema have greater aortic stiffness than non-COPD controls, and the degree of stiffness is associated with emphysema severity. The present study is the first to demonstrate that even before overt emphysema manifests, lung air-trapping is associated with carotid artery stiffness in COPD patients independent of blood pressure, age, or smoking history.
