The aim of the work is to evaluate the usefulness of the evaluation of the fractional exhaled nitric oxide (FeNO) in patients with suspected occupational asthma (OA) during the specific inhalation challenge (SIC). We evaluated 5 subjects with OA confirmed by SIC and 7 subjects with negative SIC result. In subjects with confirmed OA, but not in SIC negative subjects, a significant increase in FeNO values has been reported. In conclusion, FeNO measurement may be considered a useful tollfor the evaluation of bronchial inflammation during the SIC.

Abstract
The aim of the work is to evaluate the usefulness of the evaluation of the fractional exhaled nitric oxide (FeNO) in patients with suspected occupational asthma (OA) during the specific inhalation challenge (SIC). We evaluated 5 subjects with OA confirmed by SIC and 7 subjects with negative SIC result. In subjects with confirmed OA, but not in SIC negative subjects, a significant increase in FeNO values has been reported. In conclusion, FeNO measurement may be considered a useful tollfor the evaluation of bronchial inflammation during the SIC.
