Background/aim: 8-Hydroxy-2’-deoxyguanosine (8-OHdG) is a biomarker of oxidative stress and has been implicated in many .diseases. The aim of this study was to investigate the clinical value of plasma 8-OHdG level in patients with acute exacerbation of chronic .obstructive pulmonary disease (AECOPD)..Materials and methods: A total of 154 subjects were enrolled in this study, including 20 healthy volunteers, 24 COPD patients in the .stable phase, and 110 AECOPD patients. Peripheral blood samples, demographic information, and clinical characteristics were collected .from all subjects at the time of being recruited into the study. Plasma 8-OHdG level was detected by enzyme-linked immunosorbent .assay..Results: 8-OHdG was increased in patients with AECOPD compared to healthy subjects and patients with stable COPD, especially in .smokers. It also increased with the GOLD stage, mMRC grade, CAT score, and group level of combined COPD assessment. Additionally, .further analysis revealed that 8-OHdG was negatively correlated with FEV1., FEV1.% predicted, and FEV1./FVC and positively correlated .with C-reactive protein, procalcitonin, and neutrophil CD64..Conclusion: 8-OHdG is associated with spirometric severity, symptomatic severity, exacerbation risk, and inflammatory biomarkers in .AECOPD patients, suggesting it as a promising biomarker for reflecting disease severity and guiding the choice of optimal therapeutic .decision
