Abstract
OBJECTIVE: To review and to analyze the existing literature regarding chronic cough in children.
MATERIAL AND METHODS: We searched published articles in PubMed using the key words: cough, chronic cough, chronic cough in children, persistent cough, gastroesophageal reflux in children.
RESULTS: Cough in children is common; the majority of cases reflect respiratory infections. Cough is rarely associated to a serious disorder. All children with cough persisting for more than 8 weeks should be evaluated. A careful history, physical examination, chest x-ray, and spirometry (in an able child) are recommended for all children with chronic cough. If a diagnosis is no evident (nonspecific cough), then an approach based on characterizing the cough as "wet" or "dry" is helpful. In each case, specific etiology-based treatment is recommended when possible; otherwise, a therapeutic trial is indicated with inhaled corticosteroids (ICS) for children with dry cough (for possible asthma) and antibiotics for wet cough (for possible protracted bacterial bronchitis [PPB] or sinusitis). The treatment should be reviewed within the specified time frame for normal response. If no effect is obvious, the treatment should be stopped and alternative diagnosis considered. Multiple etiologies may need to be treated concomitantly. Every effort should be made to identify the underlying cause. Data suggests potential harmful effects of medications used for symptomatic relief of acute or chronic cough in children.
CONCLUSIONS: Medical history and physical examination, together with appropriate investigations allow the correct diagnosis of chronic cough. The diagnostic approach is summarized in Figures 1 and 2. Most cases can be managed with this algorithm. For the difficult, complex and rare cases referral to a Pediatric specialist in Allergy, Clinical Immunology and Respiratory Diseases is warranted.
