[Chronic cough in children--what to consider and how to evaluate?]

Area of Science:

• Pediatrics
• Pulmonology
• Clinical Medicine

Background:

• Chronic cough in children, defined as lasting longer than 4 weeks, presents a broad differential diagnosis.
• Early and accurate diagnosis is crucial, especially in infants under 1 year old.

Purpose of the Study:

• To outline a diagnostic and therapeutic strategy for chronic cough in pediatric patients.
• To emphasize the importance of a structured workup to identify underlying causes.

Main Methods:

• Initial assessment involves detailed history, clinical examination, chest X-ray, and spirometry (for children >5 years).
• Empirical treatment with inhaled corticosteroids, beta-agonists, and macrolide antibiotics may be considered if initial workup is inconclusive.
• Persistent cough warrants comprehensive evaluation by a pediatric pulmonologist to exclude serious conditions.

Main Results:

• A stepwise diagnostic approach can effectively manage most cases of chronic pediatric cough.
• Inconclusive initial workup may necessitate a trial of inhalation therapy and antibiotics.
• Failure to resolve symptoms points towards rarer, more severe underlying conditions.

Conclusions:

• Chronic cough in children demands a methodical diagnostic process, starting with basic investigations and progressing to specialized assessments.
• Prompt identification and management of serious conditions like cystic fibrosis or immunodeficiencies are vital for favorable outcomes.
