  • It is increasingly evident that oxidative stress plays a role in the associations between outdoor air pollution and asthma. From 204 adult asthmatics followed in the EGEA study, the mediation analysis showed a total positive effect, a direct positive effect of O3 on persistent asthma, and an indirect positive effect mediated by plasma fluorescent oxidation products levels (FlOPs; a global and cumulative biological marker related to oxidative stress) that represented 41% of the total effect.

  • The study showed that participants with higher FlOPs level at baseline had higher risk of poor asthma control eight years later. This suggests that high FlOPs level, a global oxidative stress biomarker, could be a predictor of chronic inflammatory disease evolution.
