High-resolution computed tomography in young patients with cystic fibrosis: distribution of abnormalities and...

Area of Science:

• Pediatric Pulmonology
• Radiology
• Medical Imaging

Background:

• Cystic Fibrosis (CF) is a genetic disorder affecting multiple organs, primarily the lungs.
• Early detection of pulmonary abnormalities in pediatric CF is crucial for timely intervention.
• Mild to moderate lung disease in young CF patients may not be apparent through standard pulmonary function tests alone.

Purpose of the Study:

• To evaluate pulmonary abnormalities using high-resolution computed tomography (HRCT) in young children diagnosed with cystic fibrosis (CF).
• To assess the utility of HRCT in identifying lung disease in pediatric CF patients with mild to moderate disease severity.
• To correlate HRCT findings with pulmonary function test results in this cohort.

Main Methods:

• Sixty children aged 6-10 years with mild to moderate CF underwent HRCT.
• HRCT scans were analyzed using a standardized scoring system for CF-related lung disease severity and extent.
• Pulmonary function tests, including FEV(1), FVC, and FEF(25-75), were performed and correlated with HRCT scores.

Main Results:

• Pulmonary abnormalities were detected in 75% of subjects, with air trapping (63%) and bronchiectasis (35%) being most frequent.
• Bronchiectasis was observed in 30% of children with normal pulmonary function tests (FEV(1), FVC, FEF(25-75) >85% predicted).
• HRCT scores showed significant, fair to moderate correlations with FEV(1) (r=0.36-0.46).

Conclusions:

• HRCT is effective in demonstrating a wide spectrum of pulmonary abnormalities in young CF patients with mild to moderate lung disease.
• Lung abnormalities, notably bronchiectasis, are prevalent in young children with CF, even when pulmonary function tests appear normal.
• HRCT can identify subclinical lung disease in pediatric CF, underscoring its value in early disease assessment.
