...Carlo Caffarelli; Elena Calcinai; Laura Rinaldi; Carlotta Povesi Dascola; Luigi Terracciano; Massimo Corradi Background: In asthmatics, the concentration of hydrogen peroxide (H 2 O 2 ) in exhaled breath condensate (EBC) has been found to be increased and to be related to airway inflammation...

... NO and hydrogen peroxide (H 2 O 2 ) levels in asthmatic smokers. Methods: Exhaled NO was measured by chemiluminescence and exhaled H 2 O 2 spectrophotometrically. In 7 steroid-naive asthmatic smokers exhaled NO and H 2 O 2 was measured both before and 15 min after smoking one cigarette. Data are given as median...

...W.J.C. van Beurden; P.N.R. Dekhuijzen; G.A. Harff; F.W.J.M. Smeenk Background: Because inflammation induces oxidative stress, exhaled hydrogen peroxide (H 2 O 2 ), which is a marker of oxidative stress, may be used as a non-invasive marker of airway inflammation in chronic obstructive pulmonary...
