Insights
Bronchopulmonary dysplasia (BPD) is a common chronic lung disease in premature infants. This review summarizes current literature on BPD pathogenesis and pathophysiology to aid in preventing and managing this condition in extremely low birth weight infants.
Area of Science:
- Neonatology
- Pediatric Pulmonology
- Developmental Biology
Background:
- Bronchopulmonary dysplasia (BPD) is the most frequent respiratory complication in preterm infants, impacting approximately 10,000 neonates annually in the US.
- While BPD incidence remains stable, its underlying pathophysiology has evolved due to advancements in respiratory support for extremely low birth weight (ELBW) infants.
- The disease arises from an imbalance between lung injury and repair mechanisms during lung development.
Purpose of the Study:
- To comprehensively review and synthesize current scientific literature on the pathogenesis and pathophysiology of BPD.
- To offer insights that can advance the prevention and management strategies for severe BPD in ELBW infants.
Main Methods:
- Systematic literature review of existing research on BPD.
- Synthesis of data on lung injury and repair mechanisms in developing lungs.
- Analysis of changes in BPD pathophysiology linked to modern respiratory management.
Main Results:
- The review consolidates current understanding of the complex interplay between lung injury and repair in BPD development.
- It highlights the evolving nature of BPD pathophysiology, particularly in ELBW infants.
- The literature indicates a shift in disease mechanisms influenced by improved respiratory care.
Conclusions:
- A thorough understanding of BPD pathogenesis and pathophysiology is crucial for clinical progress.
- Further research and comprehensive reviews are essential to refine prevention and management of BPD in vulnerable ELBW populations.
- This review provides a foundation for future therapeutic and preventative strategies targeting BPD.
Abstract:
Bronchopulmonary dysplasia (BPD) is a chronic lung disease of primarily premature infants that results from an imbalance between lung injury and repair in the developing lung. BPD is the most common respiratory morbidity in preterm infants, which affects nearly 10, 000 neonates each year in the United States. Over the last two decades, the incidence of BPD has largely been unchanged; however, the pathophysiology has changed with the substantial improvement in the respiratory management of extremely low birth weight (ELBW) infants. Here we have attempted to comprehensively review and summarize the current literature on the pathogenesis and pathophysiology of BPD. Our goal is to provide insight to help further progress in preventing and managing severe BPD in the ELBW infants.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
