Plasma Fibrinogen as a Biomarker of Stable and Exacerbated Chronic Obstructive Pulmonary Disease

Abstract

Background: Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable disease, but is a partially reversible chronic inflammatory condition characterized by airway obstruction. COPD remains under-diagnosed and under-treated because the only available diagnostic method at present is testing lung functions by spirometry which is not helpful to determine the severity and clinical outcomes of the disease. Circulating biomarkers are under consideration for various diseases worldwide. Plasma fibrinogen is emerging as one of the most promising biomarkers of COPD in smokers.
