Exhaled breath condensate pH and hydrogen peroxide as non-invasive markers for asthma.

Abstract

OBJECTIVE To estimate the predictive value of exhaled breath condensate (EBC) hydrogen peroxide (H2O2) concentration and pH as non-invasive markers in asthma. METHODS Fifty patients with unstable, steroid naive atopic asthma were included in the study, 25 with intermittent asthma and 25 with persistent asthma. Asthma diagnosis was according to the… (More)
