Multicenter study evaluates lung function in pediatric primary ciliary dyskinesia, highlighting methodological limitations.
Key Points
This research aims to evaluate the repeatability of Multiple Breath Washout (MBW) as a measure of lung function in pediatric patients with Primary Ciliary Dyskinesia (PCD).
Assess same-day and 28-day repeatability of MBW measurements.
Evaluate the influence of pre-test airway clearance variability on LCI results.
Analyze the impact of circadian rhythms on lung function metrics.
Consider the absence of structural imaging during MBW assessments.
LCI variability influenced by inconsistent airway clearance protocols prior to testing.
Lack of imaging made it difficult to determine true physiological changes vs. measurement artifacts.
Intra-observer and inter-observer variability in MBW quality control was unaccounted for, potentially affecting results.
Testing conducted at varying times of day introduced additional variability in lung function metrics.
