title: Efficacy and safety of inhaled steroid and cromone treatment in school-age children: a randomized pragmatic pilot study.
abstract: In the treatment of asthma, inhaled steroids are more effective than cromolyn, whereas the latter offers extreme safety. The aim of the present pilot study was to evaluate, contemporarily, efficacy and safety aspects of different asthma treatment modalities. In 75 school-age children (mean age 9.5 years; range 5.5-14.7 years), treatment of asthma was started with budesonide (BUD, n = 30), fluticasone propionate (FP, n = 30) or cromones (CROM, n = 15). BUD was used at a dose of 800 microg/day during the first 2 months and at 400 microg/day thereafter. The respective FP doses were 500 and 200 microg/day. Efficacy of the treatment was assessed by measuring forced expiratory volume in 1 second (FEV1) and by evaluating the use of bronchodilators. Side-effects of the treatment were evaluated by following growth of the children and by performing low-dose adrenocorticotropin (ACTH) testing. At 4 months FEV1 had improved by a mean of 8.2% in the BUD group and by 5.4% in the FP group (p< 0.01 vs. baseline in both groups; NS between BUD and FP groups). The use of bronchodilators had decreased from five doses/week to one dose/week in the BUD group (p< 0.05), and from three doses/week to one dose/week in the FP group (p< 0.01) (NS between the groups). In the CROM group, the FEV1 value and the use of bronchodilators did not change. The treatment was unsuccessful on the basis of FEV1 decrease and increased bronchodilator use in, respectively, 30 and 15% of the BUD-, 20 and 7% of the FP-, and 50 and 47% of the CROM-treated children. Therefore, to prevent one treatment failure in the CROM group, between three and five children would need to move to treatment with steroids. The treatment had measurable systemic effects on the basis of height standard deviation (SD) score decrease and minor adrenocortical suppression in, respectively, 60 and 30% of the BUD-, 27 and 17% of the FP-, and 20 and 0% of the CROM-treated children. Therefore, to avoid systemic effects in one steroid-treated child, three BUD- and six to 14 FP-treated children would need to move to treatment with CROM. In conclusion, in school-age children asthma should be treated first with inhaled steroids. It is probable that the best combination of efficacy and safety can be achieved by using low steroid doses.
