[Asthma in children below 5 years of age: diagnosis and treatment]

Area of Science:

• Pediatric Pulmonology
• Allergy and Immunology
• Public Health

Context:

• Asthma is the most common chronic pediatric disease, with rising prevalence posing a significant public health challenge.
• Diagnosis in young children can be challenging, often presenting after viral infections, and may be a diagnosis of exclusion, requiring careful consideration of other conditions like foreign bodies or cystic fibrosis.
• Delayed or inadequate asthma management can lead to irreversible histological lung changes, impairing lung growth and future respiratory reserve.

Purpose:

• To highlight the importance of early and accurate diagnosis of asthma in children.
• To emphasize the role of inhaled therapies, such as those administered via spacer devices and nebulizers, in managing pediatric asthma.
• To underscore the necessity of a multi-faceted treatment approach, including pharmacotherapy and environmental modifications, to reduce airway remodeling and improve outcomes.

Summary:

• Early diagnosis of pediatric asthma is vital to initiate appropriate treatment, particularly inhaled corticosteroid therapy for severe cases, aiming to mitigate airway remodeling.
• Inhaled therapies are accessible even for very young children using spacer devices and nebulizers.
• Effective asthma management extends beyond medication to include reducing viral infections, domestic pollution (including smoking), and allergen exposure, alongside crucial patient education and professional support to enhance compliance.

Impact:

• Timely intervention can prevent irreversible histological lesions and preserve lung growth and reserve in children with asthma.
• Optimizing inhaled corticosteroid dosage minimizes side effects while effectively managing severe asthma.
• Integrated management strategies, including environmental controls and robust patient education, are essential for long-term asthma control and improved quality of life in pediatric patients.
