Interpretation of lung function in infants and young children with cystic fibrosis

Area of Science:

• Pulmonology
• Pediatric Medicine
• Genetics

Background:

• Significant advances in understanding early lung disease in cystic fibrosis (CF) over the past decade.
• Growing evidence highlights the preschool years as critical for lung development and airway remodeling in CF patients.
• Early-onset lung disease in CF is increasingly recognized, necessitating timely interventions.

Purpose of the Study:

• To review lung function tests suitable for early detection of lung disease in cystic fibrosis.
• To emphasize the importance of interventions during the preschool years for CF management.
• To provide insight into the early onset and nature of lung disease in CF.

Main Methods:

• Review of studies measuring lung function in preschool children with CF.
• Analysis of longitudinal data on infection, inflammation, and structural changes.
• Evaluation of lung function tests based on their physiological underpinnings for early detection.

Main Results:

• Lung function measurement is emerging as a vital assessment tool in routine CF clinical practice.
• Studies indicate a strong association between preschool lung function, infection, inflammation, and structural changes.
• Longitudinal data are improving insights into the very early onset and nature of CF lung disease.

Conclusions:

• Interventions in the preschool years are critical for delaying and minimizing CF disease progression.
• Lung function tests are considered the most suitable current tools for early detection of lung disease in CF.
• A better understanding of early CF lung disease supports targeted therapeutic strategies.
