Preschool wheeze, genes and treatment

Area of Science:

• Pediatric Pulmonology
• Respiratory Medicine
• Clinical Pharmacology

Background:

• Preschool wheeze is a prevalent respiratory condition with unclear pathophysiology, distinct from but overlapping with infantile bronchiolitis and childhood asthma.
• Current classification attempts based on epidemiology, pathophysiology, and clinical phenotype are imperfect, impacting treatment choices and research design.
• The evidence base for common treatments like beta2 agonists, anticholinergics, corticosteroids, and leukotriene modifiers is often limited.

Purpose of the Study:

• To review the pharmacogenetics of different therapeutic options for preschool wheeze.
• To summarize current treatment recommendations for managing preschool wheeze.
• To identify and explore future research directions in the field.

Main Methods:

• Literature review of pharmacogenetics in preschool wheeze treatment.
• Synthesis of current clinical guidelines and treatment recommendations.
• Analysis of existing evidence for therapeutic interventions.

Main Results:

• Variable and often scanty evidence supports the use of main therapeutic classes for preschool wheeze.
• Evidence suggests a genetic influence on individual response variations to treatments.
• Pharmacogenetic considerations are crucial for optimizing treatment strategies.

Conclusions:

• Improved classification and understanding of preschool wheeze are needed.
• Pharmacogenetic insights offer potential for personalized treatment approaches.
• Further research is essential to refine treatment recommendations and improve patient outcomes.
