Asthma is a major cause of pediatric morbidity and mortality. In acute exacerbations of asthma, corticosteroids reduce relapses, subsequent hospital admission and the need for ß2-agonist therapy. Prednisolone is relatively short-acting with a half-life of 12 to 36 hours, thereby requiring daily dosing. Prolonged treatment course, vomiting and a bitter taste may reduce patient compliance with prednisolone. Dexamethasone is a long-acting corticosteroid with a half-life of 36 to 72 hours. It is used frequently in children with croup and bacterial meningitis, and is well absorbed orally. The purpose of this trial is to examine whether a single dose of oral dexamethasone (0.3 mg/kg) is clinically non-inferior to prednisolone (1 mg/kg/day for three days) in the treatment of exacerbations of asthma in children who attend the Emergency Department.
This is a randomized, non-inferiority, open-label clinical trial. After informed consent with or without assent, patients will be randomized to either oral dexamethasone 0.3 mg/kg stat or prednisolone 1 mg/kg/day for three days. The primary outcome measure is the comparison between the Pediatric Respiratory Assessment Measure (PRAM) across both groups on Day 4. The PRAM score, a validated, responsive and reliable tool to determine asthma severity in children aged 2 to 16 years, will be performed by a clinician blinded to treatment allocation. Secondary outcomes include relapse, hospital admission and requirement for further steroid therapy. Data will be analyzed on an intention-to-treat and a per protocol basis. With a sample size of 232 subjects (105 in each group with an estimated 10% loss to follow-up), we will be able to reject the null hypothesis - that the population means of the experimental and control groups are equal with a power of 0.9. The Type I error probability associated with this test (of the null hypothesis) is 0.05.
This clinical trial may provide evidence that a shorter steroid course using dexamethasone can be used in the treatment of acute pediatric asthma, thus eliminating the issue of compliance to treatment.

- Pediatric Respiratory Assessment Measure score (PRAM) score [ Time Frame: Day 4 ]
Pediatric Respiratory Assessment Measure score (PRAM) on Day 4. This is a compound score ranging from 0 to 12 that measures asthma severity by accounting for oxygen saturation, the presence of suprasternal retractions and/or Scalene muscle contractions, the degree of air entry and presence/type of wheezing.
A score of 0-3 indicates mild asthma, 4-7 moderate asthma and 8-12 severe asthma.
- Relapse rate [ Time Frame: 14 days ]Rate of relapse as defined as any visit to a healthcare provide as a result of asthma symptoms within 14 days of study enrollment
- Salbutamol therapies [ Time Frame: 14 days ]Frequency of salbutamol therapies given following enrolment
- Compliance with medication as assessed by interview [ Time Frame: 14 days ]Incidence of compliance with medication with regards to taking 3 doses of the medication.
- Incidence of vomiting [ Time Frame: 14 days ]Incidence of vomiting
- Relapse rate [ Time Frame: 14 days ]Relapse will be defined as any visit to a healthcare provider, for example, General Practitioner, ED, as a result of asthma symptoms.
