Descripción detallada
Practice guidelines for the management of asthma in children universally recommend systemic corticosteroids for the treatment of moderate to severe asthma exacerbations. However, these guidelines vary widely with respect to dose, frequency, method of delivery, and duration of therapy. In actual practice, there is also considerable variation among clinicians in terms of corticosteroid dosing in children hospitalized with asthma exacerbations. At the Children's Hospital of Philadelphia (CHOP) the current standard is to use an initial dose of 4.0 mg/kg/day (1.0 mg/kg every 6 hours to a maximum of 30 mg/dose) although many other pediatric hospitals use a 2.0 mg/kg/day dose (1.0 mg/kg every 12 hours to a maximum of 30 mg/dose). Systematic reviews of the literature have called for a clinical trial to evaluate the effect of different doses of corticosteroids in treating pediatric asthma patients hospitalized with exacerbations.
This study will use a randomized, double-blind, controlled trial design in order to compare the efficacy of two different steroid doses in resolving acute exacerbations of asthma in hospitalized children. Children being hospitalized for asthma exacerbations from the CHOP emergency department (ED) will be eligible for study enrollment. Those that meet enrollment criteria will be randomized to receive prednisolone either in the higher dose (1.0 mg/kg (max 30 mg) every 6 hours), or the lower dose (1.0 mg/kg (max 30 mg) every 12 hours and placebo doses at 6 hour intervals in between) for the first 48 hours of hospitalization. Once 48 hours has past, all patients still hospitalized will receive 1.0 mg/kg (max 30 mg) every 12 hours for the duration of hospitalization. Approximately 156 patients with 78 in each arm of the study will be enrolled. This study should be completed in six to eight months. A non-inferiority study design will be used. The primary outcome will be duration of hospitalization, as determined by duration of time elapsed from first dose of prednisolone administered in the emergency department (ED) until the discharge dose of albuterol is administered. Secondary outcomes will include time elapsed from the time the admission order is written until the discharge order is written, time spent in each severity level of the asthma care pathway, degree and rate of improvement in forced expiratory volume in one second (FEV1), improvement in peak expiratory flows (PEF), improvement in asthma symptom scores, and rate of relapse after discharge.
