Management of Recurrent Preschool, Doctor-Diagnosed Wheeze

Area of Science:

• Pediatrics
• Respiratory Medicine
• Allergy Immunology

Background:

• Wheezing is a common condition in preschoolers, affecting approximately 50% of children before age six.
• Recurrent preschool wheeze is categorized into typical (asthma, bronchiolitis/bronchitis) and atypical types, necessitating distinct diagnostic and management approaches.

Purpose of the Study:

• To outline diagnostic criteria for recurrent preschool wheeze, emphasizing the role of bronchodilator responsiveness in confirming asthma.
• To provide guidance on the assessment and management of typical and atypical preschool wheeze, including the utility of impulse oscillometry (IOS) and atopy assessment.
• To highlight treatment strategies for acute wheeze episodes and long-term management to reduce exacerbations.

Main Methods:

• Classification of recurrent preschool wheeze into typical and atypical forms.
• Diagnostic confirmation of asthma through bronchodilator responsiveness testing.
• Assessment of atopy using skin prick tests or serum IgE levels.
• Utilization of impulse oscillometry (IOS) to evaluate airway hyperresponsiveness.
• Review of treatment modalities including bronchodilators, hypertonic saline, nebulized adrenaline, systemic steroids, CPAP, and inhaled corticosteroids or montelukast.

Main Results:

• Bronchodilator responsiveness is key to diagnosing asthma in preschool children.
• Impulse oscillometry (IOS) aids in identifying airway hyperresponsiveness, a hallmark of asthma.
• Atopy assessment is important for a comprehensive evaluation.
• Treatment varies based on diagnosis, with specific therapies for asthma and acute bronchiolitis.
• Long-term management strategies like inhaled corticosteroids or montelukast can decrease asthma exacerbation rates.

Conclusions:

• Early and accurate diagnosis of preschool wheeze, particularly asthma, is essential for timely and effective management.
• Atypical preschool wheeze requires referral to a pediatric respirologist for specialized assessment.
• Persistent preschool wheeze into school age underscores the importance of early intervention and optimal care.
