Abstract

BACKGROUND: Asthma and allergic diseases are heterogeneous. Measurement of biomarkers in exhaled breath condensate (EBC) may help to discriminate between different phenotypes and may assist with clinical prognostication. OBJECTIVES: We aimed to assess associations between total nitric oxide products (NOx ) in EBC and different allergic phenotypes and lung function in young and middle-aged adults. METHODS: Cross-sectional analyses were nested within two Australian longitudinal studies, the Melbourne Atopy Cohort Study (MACS, mean age 17.8 years) and the Tasmanian Longitudinal Health Study (TAHS, mean age 49.4 years). Levels of EBC NOx were determined by Griess-reaction fluorescent method. Ass..
