Definitions and early natural history

Area of Science:

• Pediatric immunology
• Respiratory medicine
• Developmental biology

Background:

• Asthma is linked to mucosal and immunological development.
• Early wheezing in infants significantly increases asthma risk.
• Atopy and elevated IgE levels are strong indicators of asthma development.

Purpose of the Study:

• To develop a predictive algorithm for asthma likelihood in primary care.
• To assess the feasibility of early childhood asthma monitoring using lung function and sputum tests.
• To explore in-utero programming and developmental factors in asthma.

Main Methods:

• Utilizing presenting symptoms and diagnostic investigations for prediction.
• Investigating regular lung function testing and induced sputum analysis.
• Examining airway mucosal maturation and immunological development deviations.

Main Results:

• High probability of asthma associated with early wheeze, atopy, and specific tests.
• Current diagnostic methods confirm asthma through lung function and inflammation.
• Significant knowledge gaps exist regarding predictive algorithms and early monitoring.

Conclusions:

• Predictive tools for general practitioners are needed.
• Feasibility of early childhood monitoring requires further investigation.
• Understanding developmental origins is crucial for asthma prevention and management.
