Background Inhaled corticosteroids are effective in the treatmentof children with asthma. It is uncertain how inhaled corticosteroidscompare with oral corticosteroids in the management of severeacute disease.
Methods We performed a double-blind, randomized trial involving100 children five years of age or older who had severe acuteasthma (indicated by a forced expiratory volume in one second[FEV1] that was less than 60 percent of the predicted value)and in whom the results could be evaluated. All were treatedwith an aggressive bronchodilator regimen and received one doseof either 2 mg of inhaled fluticasone through a metered-doseinhaler with a spacer or 2 mg of oral prednisone per kilogramof body weight. They were assessed hourly for up to four hours.
Results The mean (±SD) base-line FEV1 as a percentageof the predicted value was 46.3±12.5 in the fluticasonegroup (51 subjects) and 43.9±9.9 in the prednisone group(49 subjects). The FEV1 increased by a mean of 9.4±12.5percentage points in the fluticasone group and by 18.9±9.8percentage points in the prednisone group four hours after therapy(P< 0.001). None of the children in the prednisone grouphad a reduction in FEV1 as a percentage of the predicted valuefrom base line to four hours, as compared with 25 percent ofthose in the fluticasone group (P<0.001). Sixteen (31 percent)of the children treated with fluticasone were hospitalized,as compared with five (10 percent) of those treated with prednisone(P=0.01).
Conclusions Children with severe acute asthma should be treatedwith oral prednisone and not with inhaled fluticasone or a similarinhaled corticosteroid.
