Metabolite Identification
Common Name8-Isoprostane
Description8-isoprostane concentrations are elevated in asthma and increase with the clinical severity and during acute asthma episodes. Isoprostane is formed in the airways of asthmatic patients from peroxidation of poly-unsaturated fatty acids in cell membranes, the effect of reactive oxygen species resulting of the NADPH oxidase of eosinophils, neutrophils and alveolar macrophages, which produces superoxide anion which undergoes dismutation to H2O2. (PMID 16354413 ). 8-isoprostane is also elevated in Bronchopulmonary dysplasia, which remains an important cause of morbidity and mortality in extremely premature newborn infants receiving intensive care and is the most common contributing factor to severe respiratory morbidity and mortality in early childhood. (PMID 14980283 ). 8-Isoprostaglandin F(2a) is a marker of oxidative stress in the aqueous humour of patients with exfoliation syndrome (XFS) (PubMed ID 12598453).
