Study information

Scientific title


TWICS (Treatment of Wheeze In Children with Steroids)

Study hypothesis

The outcome for preschool children (10 months to 60 months) admitted to the hospital with an attack of wheeze triggered by clinical viral infection (preschool viral wheeze) and treated with oral steroids will be no different than those children treated with placebo (primary null hypothesis).

Secondary (null) hypotheses are that compared with oral placebo, treatment of hospitalised children with preschool viral wheeze with oral prednisolone will not:
1. Reduce the severity of respiratory distress at 4, 12, and 24 hours
2. Reduce the total severity of the attack, or the total amount of inhaled bronchodilators
3. Reduce the risk of significant hypoxia or re-admission within 4 weeks

Ethics approval

1. Fife and Forth Valley Local Research Ethics Committee (MREC ref: 05/S0501/7)
2. Leicestershire Local Research Ethics Committee Two (LREC ref: 05/Q2502/19)
3. Medicines and Healthcare products Regulatory Agency (MHRA) (CTA Number 23071/0001/001-0001)

Study design

Trial type


Patient information sheet


Preschool wheeze: In children between 1 and 5 years the phenotype of 'asthma' is characterised by transient episodes of wheeze triggered by viral colds with no or few interval symptoms


By double-blind, stratified (by centre) randomisation, children will receive either oral corticosteroids for 5 days or placebo along with inhaled bronchodilator therapy (frequency and mode of delivery device decided by the clinician). The dose of the oral corticosteroid, prednisolone will be 20 mg for 2 to 5 year olds and 10 mg for children under age of 2 years.

Intervention type



Not Specified

Drug names


Primary outcome measures

Length of stay in hospital, i.e. time from randomisation to discharge from the hospital which will be assessed in two ways: first when the child was felt fit to be discharged by a clinician and second when child was discharged home.

Secondary outcome measures

1. Median symptom score (Preschool Respiratory Assessment Measure [PRAM] score) and parental symptom score (mean 7 day)
2. Total use of inhaled bronchodilators during hospitalisation (from notes) and total for 7 days post discharge (from parental diary and clinical notes)
3. Complications:
3.1. Hypoxia
3.2. Pediatric Intensive Care Unit (PICU) admission
3.3. Readmission within 1 month and withdrawal from the study
