Assessment of Induced Sputum Cellularity in COPD Patients Belonging to Two Different Classes of Air Pollution Exposure.

CONCLUSIONS: In conclusion, we showed that non-professionally exposed patients with COPD residing in highly-polluted urban areas had greater airway inflammation in terms of sputum neutrophils compared to a population with very similar characteristics, living in rural areas with lower outdoor pollution. The results of this pilot study may be relevant for the long term effect of environmental outdoor pollution in vulnerable patients like those with COPD.
