AB  - Introduction: Chronic obstructive pulmonary disease (COPD) is a common airway inflammatory disorder with structural degradation of the airway tissue. Previous reports showed that patients with COPD had EBT lower than normal subjects. Recently, a new combined COPD assessment was established based on the symptoms, spirometric classification and risk of exacerbation (GOLD 2011).Objectives: Evaluate the EBT in COPD patients according to the new combined COPD assessment and compare to healthy subjects. Methods: EBT was measured (using the X-halo, Delmedica, Singapore) in 80 COPD patients (FEV1% 54±14, age 60±8 years, 46 males) and 80 healthy controls. Lung function, COPD Assessment Test (CAT), exacerbations and previous treatment was performed.Results: There was not differences EBT between COPD patients 34,2°C vs healthy subjects 33,9°C. There was no correlation between EBT with FEV1% (r=0,23) and EBT with CAT (r=0,01) but patients with previous exacerbations had EBT more than patients without exacerbations (34,7°C vs 33,9°C, p<0,001) According to the new combined COPD assessment (20 subjects for each group), the EBT was: Group A 34,1°C, Group B 33,9°C, Group C 34,7°C and Group D 34,8°C. (p<0,001 between Group B vs Group C and D).Conclusion: Our results showed that COPD patients with frequent exacerbations, 2 or more per year, had increased of Exhaled Breath Temperature, therefore may reflect inflammation in the COPD lung.
