Lowered Glutathione‐Peroxidase Activity in Asthmatic Patients with Food and Aspirin Intolerance

Abstract

In analogy with findings from animal experiments, people with low glutathione-peroxidase (GSH-Px) activity could be expected to have altered sensitivities to effects of drugs, chemicals and possibly food. We have investigated GSH-Px activity in 12 patients with intrinsic asthma and food and aspirin intolerance. Ten of the 12 patients had very low or low GSH-Px activity and the frequency of low GSH-Px activity in this group was statistically significant (P less than 0.001) compared with the control material of age- and sex-matched healthy individuals. Our finding of lowered GSH-Px activity in patients with aspirin intolerance may indicate the involvement of hitherto unknown mechanisms in the pathogenesis of asthmatic disorders.
