Evidence of eosinophilic cationic protein (ECP) in 10\% hypertonic saline-induced sputum was assessed, together with pulmonary function tests, respiratory resistance, exhaled nitric oxide (FeNO) and an Asthma Control Questionnaire (ACQ-5).Results: ECP levels in late-phase sputum (117.6{\textpm}144.7 mg/L at study entry) were significantly decreased 65.7{\textpm}89.5 (p=0.019) at 4 weeks in the FFC group, but not in the SFC group. FeNo levels (44.8{\textpm}23.5 ppb at study entry) were also significantly decreased to 37.8{\textpm}23.5 (p=0.025) at 4 weeks in the FFC group. None of the indexes of pulmonary function tests or respiratory resistance changed significantly in either group during the study period. ACQ-5 scores showed no significant change; however, they tended to improve in the FFC group.Conclusion: This study suggests that FFC may offer better control of residual eosinophilic inflammation in distal airways than SFC therapy.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/44/Suppl_58/P2428}, eprint = {https://erj.ersjournals.com/content}, journal = {European Respiratory Journal} }
