Persistent and progressive long-term lung disease in survivors of preterm birth

Area of Science:

• Neonatology
• Pediatric Pulmonology
• Respiratory Medicine

Background:

• Preterm birth affects 11% of global births, with rising rates in many countries.
• Neonatal care advances improve survival for infants born at lower gestational ages (GA).
• Infants born <32 weeks GA often experience adverse respiratory outcomes and increased healthcare use into childhood.

Purpose of the Study:

• To review the long-term pulmonary outcomes in contemporary preterm infants.
• To examine the mechanisms contributing to long-term respiratory morbidity.
• To discuss knowledge gaps and potential targeted treatments for respiratory complications.

Main Methods:

• Literature review of contemporary research on preterm birth and long-term respiratory outcomes.
• Analysis of studies investigating the mechanisms of persistent lung disease.
• Synthesis of information on current and potential therapeutic strategies.

Main Results:

• Preterm infants, especially those with bronchopulmonary dysplasia (BPD), exhibit increased respiratory symptoms and hospitalizations.
• Altered lung structure and persistent, sometimes declining, lung function are observed throughout childhood and into adulthood.
• The underlying mechanisms for progressive lung disease in preterm survivors remain unclear.

Conclusions:

• Preterm birth leads to significant long-term respiratory morbidity, impacting lung health into adulthood.
• Understanding the mechanisms of persistent lung disease is crucial for developing effective interventions.
• Further research and targeted treatments are needed to improve respiratory outcomes for preterm survivors.
