Objective: Airway inflammation and oxidative stress biomarkers increase in chronic obstructive pulmonary disease (COPD) and this is thought to be related to faster decrease in lung functions. Systemic markers of oxidative stress include nitric oxide (NO) and malonyl dialdehyde (MDA), while antioxidant markers are erythrocyte superoxide dismutase (SOD) and gluthathion-peroxidase (GSH-Px). We investigated the relationship between levels of systemic oxidative/antioxidant markers and functional parameters.
