Chronic cough in children

Area of Science:

• Pediatrics
• Pulmonology
• Infectious Diseases

Background:

• Chronic cough is variably defined, often persisting after viral or pertussis-like illnesses.
• Management focuses on diagnosis and targeted treatment, with treatment trials sometimes used diagnostically.

Purpose of the Study:

• To outline diagnostic and management strategies for chronic cough in children.
• To differentiate between common causes like asthma and protracted bacterial bronchitis (PBB).

Main Methods:

• Review of diagnostic approaches for chronic cough.
• Emphasis on time-limited empirical treatment trials.
• Criteria for investigating specific causes of suppurative lung disease.

Main Results:

• Natural resolution is common; diagnostic treatment trials should be time-limited.
• Asthma is over-diagnosed in isolated dry cough; PBB is a consideration for chronic wet cough.
• PBB often responds to antibiotics, but further investigation is needed for refractory cases.

Conclusions:

• A systematic approach to chronic cough diagnosis is crucial.
• Protracted bacterial bronchitis (PBB) is a treatable cause of chronic wet cough in children.
• Further investigation is essential for children with PBB unresponsive to treatment or with concerning features.
