EXHALED AIR TEMPERATURE IN CHILDREN WITH BRONCHOPULMONARY DYSPLASIA

International audienceBackground. Because they have similar functional and clinical profiles, bronchopulmonary dysplasia (BPD) survivors are often treated as asthmatic patients. In truth, very little is known about the possible biochemical and inflammatory mechanisms playing a part in BPD survivors' lungs. The aim of this study was to measure exhaled breath temperature in BPD survivors by comparison with asthmatic cases and healthy controls. Methods. Three groups of age-matched adolescents (n=17 each), i.e. BPD survivors (gestational ages < 31 weeks, birth weights < 1500 g), asthmatic subjects and healthy controls, underwent exhaled breath temperature and exhaled nitric oxide measurements, and spirometry. Results. Exhaled breath temperature was significantly lower in the BPD survivors (26.72°C [25.11-27.57]) than in the asthmatic patients (29.60°C [29.20-30.02], p
