Are Babies Born Preterm High-Risk Asthma Candidates?

Area of Science:

• Pediatric Pulmonology
• Neonatology
• Immunology

Background:

• Asthma risk in preterm infants is debated, with impaired pulmonary function being common.
• Preterm infants are susceptible to respiratory infections, bronchiolitis, and viral wheezing, potentially preceding asthma.
• The interplay between atopic sensitization, intestinal microbiome, and immune maturation is crucial in understanding asthma development.

Purpose of the Study:

• To review the current understanding of prematurity-associated asthma.
• To explore factors contributing to asthma onset in preterm infants.
• To identify potential pathways for improved prediction of this asthma phenotype.

Main Methods:

• Literature review of prematurity-associated asthma.
• Discussion of pulmonary function, infections, and immune system development.
• Analysis of the roles of atopic sensitization, intestinal microbiome, diet, and pollution.

Main Results:

• Preterm birth is linked to impaired lung function and increased susceptibility to respiratory infections.
• Viral infections and wheezing in early life are associated with subsequent asthma development.
• Atopic sensitization, gut microbiome alterations, diet, and environmental pollution are implicated factors.

Conclusions:

• Understanding the multifaceted factors influencing asthma onset in preterm infants is essential.
• Further research into prematurity-associated asthma may lead to better predictive models.
• Interventions targeting the microbiome, immune maturation, diet, and pollution could mitigate asthma risk.
