LCI and FEV1 worsened with both PEx and UIC and did not recover at the next consecutive follow-up visit. At the first stable visit after follow-up, neither LCI or FEV1 recovered to baseline for the PEx group, and, for the UIC group, only FEV1 recovered.Conclusion: In school-age children with CF, lung function does not recover to baseline after PEx and, as detected by LCI, recovery is also incomplete after UIC.FootnotesCite this article as: European Respiratory Journal 2020; 56: Suppl. 64, 4314.This abstract was presented at the 2020 ERS International Congress, in session “Respiratory viruses in the "pre COVID-19" era”.This is an ERS International Congress abstract.
