Recurrent respiratory infections between immunity and atopy

Area of Science:

• Pediatric Pulmonology
• Clinical Immunology
• Infectious Diseases

Background:

• Recurrent respiratory infections (RRIs) are common in children, often linked to factors like small airway size or immune system immaturity.
• While many RRIs resolve spontaneously, some indicate serious underlying diseases requiring prompt diagnosis.
• Identifying 'red flags' such as early symptom onset or growth issues is crucial for differential diagnosis.

Purpose of the Study:

• To provide pediatricians with a structured approach for diagnosing the causes of recurrent respiratory infections in children.
• To create a diagnostic roadmap based on scientific literature and clinical practice.

Main Methods:

• Literature review and clinical practice data synthesis.
• Development of a diagnostic roadmap categorizing RRIs into six main areas.
• Identification of key differentiating factors and 'red flags'.

Main Results:

• The roadmap categorizes potential causes of RRIs into six macro areas: immunodeficiencies, simple minimal genetic immunodeficiency, atopy, obesity, nutritional deficiencies, and autoinflammatory/complex diseases.
• It highlights specific red flags that suggest more complex underlying conditions beyond transient immune immaturity.

Conclusions:

• A systematic diagnostic roadmap can significantly aid pediatricians in differentiating the causes of recurrent respiratory infections in children.
• Early and accurate diagnosis is essential for managing RRIs effectively, distinguishing between transient issues and more complex diseases.
