The 8-Year-Old with Recurrent Wheeze and a Normal Spirometry
An 8-year-old boy has had four episodes of nighttime cough and wheeze in the past year, each lasting about a week, worse with colds and after soccer. He has no eczema, no food allergy, and no family history of asthma. Between episodes he is completely well. Spirometry today (asymptomatic) is normal with no bronchodilator response. His mother is worried about 'labeling him' with asthma and asks whether he can just use cough syrup. He is otherwise healthy, vaccinated, and growing normally.
1. Does a normal inter-visit spirometry exclude asthma, and what is your next step?
Read the worked answer
No-normal spirometry between episodes does not exclude asthma. The pattern (recurrent, triggered by exercise and viral illness, nocturnal) is classic, and the diagnosis is clinical in this age group. The next step is to demonstrate variable airflow obstruction: either repeat spirometry during symptoms, or a trial of a short-acting bronchodilator with symptom diary, or a formal bronchoprovocation/exercise challenge if available. A therapeutic trial of a low-dose inhaled corticosteroid with a written action plan and follow-up in 4–6 weeks is reasonable and diagnostic as well as therapeutic. Do not order allergy testing routinely in the absence of allergic features. Cough syrup with antihistamines or codeine is not appropriate and does not address airway inflammation.
2. How do you frame the 'labeling' concern for the mother?
Read the worked answer
Acknowledge the concern and reframe: the label is a tool for getting the right treatment, not a life sentence. Untreated recurrent airway inflammation risks exacerbations, missed school, and exercise limitation; a diagnosis enables a controller inhaler that can be stepped down if he is well controlled for months. Explain that many children with viral-triggered wheeze improve, and that the plan will be reassessed. Provide an asthma action plan, teach inhaler technique with a spacer, and identify triggers (cold air, exercise) with pre-exercise SABA as needed. Document a follow-up to reassess control using a validated tool and to consider step-down if symptom-free.
