Chemical intermediates scavengers in the therapy of allergic diseases

Although oxidative status has been related to several pathophysiologic proc esses, there is not a well established connection between antioxidant defen se and allergy. An imbalance of reactive oxygen species is related to infla mmation in allergic diseases. Antioxidant enzymes are involved in cell deto xification. This primary antioxidant defence system might work against alle rgic's symptoms. In this work, arguments in favour of the potential of free radical scavengers in antioxidant therapy for allergic patients are discus sed.
