Background Complete blood count parameters provide novel inflammatory markers, namely
neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). We aimed to …

Purpose Frequent exacerbators are a specific phenotype of chronic obstructive pulmonary
disease (COPD), whose clinical characteristics and prognostic biomarkers during severe …

Background COPD exacerbations requiring hospitalization increase morbidity and mortality.
Although most COPD exacerbations are neutrophilic, approximately 10%–25% of …

COPD is characterized by a pulmonary and systemic inflammatory process. Several authors
have reported the elevation of multiple inflammatory markers in patients with COPD; …

Objectives We aimed to investigate the importance of neutrophil–lymphocyte ratio (NLR) in
patients with chronic obstructive pulmonary disease (COPD) for identifying the severity of …

Aim Increased dyspnea, sputum volume, and purulence are subjective symptoms in COPD
patients. To diagnose COPD exacerbations with chronic respiratory failure (CRF) and to …

Abstract Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPDs) are one of
the most important clinical aspects of the disease, and when requiring hospital admission …

Introduction Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has
the highest mortality rate and medical costs. The neutrophil‐to‐lymphocyte ratio (NLR) and …

Background Blood neutrophil-to-lymphocyte ratio (NLR) and blood eosinophils (B-Eos) are
emerging biomarkers in COPD. This study examined whether they could predict acute …

Background Neutrophil-to-lymphocyte ratio (NLR) is a biomarker of inflammation in chronic
obstructive pulmonary disease (COPD) patients. But, a meaningful threshold and the …
