P133 Lung clearance index is a reproducible and sensitive measure of airways disease in bronchiectasis

Lung clearance index is a sensitive, repeatable and practical measure of airways disease in adults with cystic fibrosis.

BACKGROUND Lung clearance index (LCI) is a sensitive marker of early lung disease in children but has not been assessed in adults. Measurement is hindered by the complexity of the equipment required. The aims of this study were to assess performance of a novel gas analyser (Innocor) and to use it as a clinical tool for the measurement of LCI in cystic fibrosis (CF). METHODS LCI was measured i...

Lung clearance index in adults with non-cystic fibrosis bronchiectasis

BACKGROUND Lung clearance index (LCI) is a measure of abnormal ventilation distribution derived from the multiple breath inert gas washout (MBW) technique. We aimed to determine the clinical utility of LCI in non-CF bronchiectasis, and to assess two novel MBW parameters that distinguish between increases in LCI due to specific ventilation inequality (LCIvent) and increased respiratory dead spac...

Lung clearance index in CF: a sensitive marker of lung disease severity.

The reproducibility and responsiveness of the lung clearance index in bronchiectasis.

Lung clearance index (LCI) is a potential clinical outcome marker in bronchiectasis. Its responsiveness to therapeutic intervention has not been determined. This study evaluates its responsiveness to a session of physiotherapy and intravenous antibiotic treatment of an exacerbation.32 stable and 32 exacerbating bronchiectasis patients and 26 healthy controls were recruited. Patients had LCI and...

Is Lung Clearance Index (LCI) Affected by the Severity of Lung Disease in CF?

Background: LCI has been proven an effective tool in the detection of lung disease in CF. Objectives: a) To assess the correlation of ventilation inhomogeneity indices with structural damages of the lung, among different groups of disease severity and b) To compare the associations among MBW parameters with spirometry and CT. Method: Forty-four children and adolescents with CF participated in t...
