A 4-year-old with recurrent wheeze whose parents want an 'asthma label'
A 4-year-old girl is brought to clinic with her third episode of wheeze in 12 months. Each episode followed a cold, lasted about a week, and responded to salbutamol given by spacer in the emergency department. Between episodes she is well and active. She has eczema and her father has asthma. She attends nursery, and the family home has visible damp and a pet cat. She has never been admitted, has never needed oral steroids, and has no nocturnal symptoms between colds. Examination today: well, respiratory rate 24/min, no recession, chest clear, no clubbing, growth normal. Spirometry is not feasible at this age. The parents want to know whether she 'has asthma' and whether she needs a daily inhaler.
1. How would you frame the diagnosis at this age, and what features in the history raise or lower your level of concern?
Read the worked answer
Framing: at 4 years, a definitive asthma label is often avoided; the working diagnosis is preschool wheeze with an atopic phenotype and a high probability of asthma. Diagnosis is clinical - spirometry is not feasible, and a therapeutic trial plus review is the pragmatic approach.
Features that raise concern for asthma:
- Recurrent wheeze triggered by viral colds, with response to bronchodilator.
- Atopy (eczema) and parental asthma - both increase the probability of persistent asthma.
- Symptom-free intervals with normal examination.
Features that lower concern / suggest alternative:
- Symptoms only with colds and never between them, with no exercise or nocturnal symptoms, and no oral-steroid requirement - this pattern is common and often remits.
- Normal growth and examination, no clubbing, no focal signs, no vomiting or choking (argues against aspiration, reflux, foreign body).
What would make me look for something else: failure to respond to bronchodilator, focal or persistent signs, faltering growth, clubbing, chronic wet cough, or symptoms from birth - consider cystic fibrosis, primary ciliary dyskinesia, immunodeficiency, aspiration, or a structural airway lesion.
2. The parents ask for a daily preventer inhaler. What is your decision and how do you justify it, including the role of the home environment?
Read the worked answer
Decision: I would not start a daily preventer at this point on the history given, but I would set clear criteria for when to start and review in 4–8 weeks.
Why not now:
- She has had three short, cold-triggered episodes, no admissions, no oral steroids, no interval or nocturnal symptoms, and normal examination.
- The absolute benefit of daily inhaled corticosteroids in this pattern is small, and there are real costs: growth effects, adherence burden, and medicalising a child who may remit.
- Guidelines support a trial of preventer where there is frequent interval symptoms, frequent reliever use, or exacerbations requiring oral steroids - none of which she currently has.
What I would do instead:
- Ensure correct spacer technique and a written action plan for colds.
- Address the home environment: damp and mould remediation, and discuss the cat (at minimum keep it out of the bedroom) - environmental advice is part of management, not an alternative to it.
- Review the frequency of reliever use; if she needs salbutamol more than twice a week, wakes at night, or has an exacerbation needing oral steroids, I would start a low-dose inhaled corticosteroid trial and reassess after 8–12 weeks.
Justification to the parents: explain that the aim is to treat only if the pattern warrants it, that the plan will be revisited, and that we are not dismissing the diagnosis.
3. Six months later she has had two courses of oral prednisolone and wakes coughing twice a week. Outline your management plan and the safety points you would cover.

She now meets criteria for daily controller therapy: frequent interval symptoms, nocturnal cough, and exacerbations requiring oral steroids.
Plan:
- Start a low-dose inhaled corticosteroid via a valved spacer with a mouthpiece or well-fitting mask, with a demonstration and observed technique at every visit.
- Give a written asthma action plan covering increasing reliever use and when to start oral steroids or seek urgent care.
- Review in 4–8 weeks to assess control, adherence, technique and growth; step up only after checking these.
- Reassess the diagnosis if she does not respond - consider alternative diagnoses and referral to paediatric respiratory services.
- Continue environmental measures and consider allergy assessment if symptoms persist.
Safety points to cover:
- Rinse the mouth after inhaled steroid to reduce oral candidiasis and dysphonia.
- Growth: measure height at each review - small transient effects on growth velocity are possible, but uncontrolled asthma also impairs growth; the balance favours treatment.
- Reliever overuse is a warning sign, not a solution; frequent salbutamol indicates poor control.
- Oral steroid courses: no more than a few per year should trigger a review; repeated courses signal the need for step-up.
- Emergency plan: when to call an ambulance, and that a child who is drowsy, exhausted or silent-chested is an emergency.
- Adherence: explore barriers honestly rather than escalating the dose.
