Chronic interstitial lung diseases in children: diagnosis approaches

Area of Science:

• Pediatric Pulmonology
• Rare Respiratory Diseases
• Interstitial Lung Disease

Background:

• Children's interstitial lung disease (chILD) encompasses diverse rare respiratory disorders.
• These conditions involve inflammatory and fibrotic lung changes in children.
• chILD is categorized by etiology, including environmental, systemic, primary lung, and infant-specific types.

Purpose of the Study:

• To provide an updated review of chILD pathophysiology and diagnostic approaches in immunocompetent children.
• To discuss current knowledge regarding genetic causes of chILD.
• To highlight challenges in classification and the need for improved patient management and prognosis.

Main Methods:

• Literature review focusing on recent advancements in chILD research.
• Synthesis of information on pathophysiology, genetics, and diagnostic strategies.
• Analysis of current classifications and their limitations.

Main Results:

• chILD presents a broad spectrum of diseases with varied expressions.
• Recent genetic discoveries have identified some causative factors, but correlations with disease presentation are still lacking.
• Despite management improvements, chILD remains associated with significant morbidity and mortality.

Conclusions:

• International collaboration is crucial for building larger patient cohorts to advance chILD knowledge.
• Personalized care and structured genetic counseling are essential for affected families.
• The ultimate goal is to improve the transition to adulthood for children with chILD.
