Alpha-1-antitrypsin deficiency (AATD) and tobacco smoke play a key role in the pathogenesis of early-onset emphysema. Differences in AATD-related chronic obstructive pulmonary disease stages imply the existence of modifying factors associated with disease severity. We present two male patients with emphysema caused by severe AATD (PiZZ genotype). Both are former smokers and have epoxide hydrolase low-activity phenotype. Extremely high level of oxidative stress (high urinary 8-oxo-7,8-dihydro-2'-deoxyguanosine), increased inflammation (high serum CRP), and GSTP1 105Val mutation were found in patient with a worse lung function and prognosis. These data provide more evidence that oxidative stress-related gene variants and inflammation are associated with worse symptoms of AATD-related emphysema. Therefore, prevention against severe stage of AATD-related emphysema would include early identification of the risk gene variants, cessation or never smoking, and treatment with anti-inflammatory ...and anti-oxidant drugs. Additionally, urinary 8-oxodG could be a candidate for predictive biomarker for routine assessment of the oxidative stress level in AATD patients.
