Interstitial lung disease in infancy and early childhood: a clinicopathological primer

Area of Science:

• Pediatric Pulmonology
• Rare Diseases
• Genetic Medicine

Background:

• Children's interstitial lung disease (chILD) presents a heterogeneous group of respiratory conditions unique to pediatric populations.
• Existing classification systems categorize chILD based on age of onset (infancy vs. any age).

Purpose of the Study:

• To provide a comprehensive overview of clinical, genetic, and histological features of chILD.
• To assist healthcare providers, particularly those outside specialist centers, in the clinical assessment and diagnosis of chILD.

Main Methods:

• Multidisciplinary approach integrating clinical, radiological, genetic, and histological data.
• Review of diagnostic evaluation pathways, including indications for lung biopsy.
• Synthesis of current knowledge on chILD entities.

Main Results:

• chILD classification relies on a combination of clinical presentation, imaging, genetic analysis, and pathology.
• Lung biopsies are reserved for cases where other methods fail or in severe, undiagnosed respiratory distress.
• Understanding these diverse findings is crucial for accurate diagnosis.

Conclusions:

• Accurate diagnosis of chILD requires a thorough, multidisciplinary evaluation.
• This review offers guidance for rational diagnostics and clinical assessment of chILD.
• Improved diagnostic strategies are essential for managing these rare pediatric lung diseases.
