Utility of neutrophil to lymphocyte ratio in the prediction of inflammation and COPD mortality
2025
Overview
Introduction: The Neutrophil-to-Lymphocyte Ratio (NLR) has been utilized to predict clinical outcomes in cardiovascular diseases, infectious diseases, and solid tumors and it has a potential association with the severity of Chronic Obstructive Pulmonary Disease (COPD). This study aimed to determine whether NLR is a possible predictor of inflammation severity and mortality in COPD. Methodology: A prospective analysis of NLR in 70 COPD patients, and its relation with biochemical, lung function parameters, and mortality was assessed. Results: NLR was negatively associated with oxygen saturation (p < 0.05) and positively related to C-reactive protein (CRP) (p < 0.05), matrix metalloproteinase-9 (MMP-9) (p ≤ 0.001), tissue inhibitor of metalloproteinase-1 (TIMP-1) (p < 0.05), MMP-9/TIMP-1 ratio (p < 0.05), and the modified Medical Research Council dyspnea scale (mMRC) score (p < 0.05). Deceased patients had significantly higher NLR (p < 0.05). Older age and lower levels of saturation were independently associated with higher mortality in COPD patients (p < 0.05). Conclusions: NLR in COPD correlates with inflammation and protease/antiprotease balance, with elevated NLR detected in deceased patients. These findings suggest that NLR can be a helpful clinical marker in COPD.
