Infant Pulmonary Function Testing in Pediatric Diffuse Parenchymal Lung Disease

Area of Science:

• Pediatric Pulmonology
• Rare Respiratory Diseases
• Infant Diagnostics

Background:

• Diffuse parenchymal lung disease (DPLD) encompasses rare chronic respiratory disorders in children.
• Diagnosing and monitoring DPLD in infants presents significant challenges due to limited noninvasive methods.
• Current quantitative follow-up techniques for infant DPLD are suboptimal.

Purpose of the Study:

• To review available data on infant pulmonary function testing (iPFT) in pediatric DPLD.
• To highlight the potential of iPFT in understanding DPLD pathophysiology.
• To elucidate the role of iPFT in managing DPLD in infants.

Main Methods:

• Review of existing literature on infant PFT in DPLD.
• Analysis of diverse iPFT alteration patterns across different DPLD types.
• Synthesis of findings to inform diagnosis and management.

Main Results:

• Distinct iPFT alteration patterns observed in specific infant DPLDs, including surfactant dysfunction disorders and neuroendocrine cell hyperplasia of infancy.
• These patterns enhance understanding of disease pathophysiology.
• iPFT findings can potentially aid in diagnosis and management of infant DPLD.

Conclusions:

• Infant PFT alterations provide insights into DPLD pathophysiology, diagnosis, and management.
• The complexity of comprehensive PFT in infants limits its routine use.
• Developing precise, accessible infant pulmonary function evaluation techniques and fostering international collaboration are crucial for improving DPLD management in infants.
