Abstract
It has been hypothesized that exhaled breath temperature (EBT) is related to the degree of airway inflammation/remodeling in asthma. The purpose of this study was to evaluate the relationship between the level of airway response to exercise and EBT in a group of controlled or partly controlled asthmatic children. Fifty asthmatic children underwent measurements of EBT before and after a standardized exercise test. EBT was 32.92?±?1.13 and 33.35?±?0.95°C before and after exercise, respectively (P?<?0.001). The % decrease in FEV(1) was significantly correlated with the increase in EBT (r?=?0.44, P?=?0.0013), being r?=?0.49 (P?<?0.005) in the children who were not receiving regular inhaled corticosteroids (ICS) and 0.37 (n.s.) in those who were. This study further supports the hypothesis that EBT can be considered a potential composite tool for monitoring asthma. Pediatr Pulmonol. © 2011 Wiley-Liss, Inc.
