Objective:To compare the effect of inhaled budesonide given daily or as-needed on mild persistent childhood asthma.Patients, design and interventions:176 children aged 5–10 years with newly detected asthma were randomly assigned to three treatment groups: (1) continuous budesonide (400 μg twice daily for 1 month, 200 μg twice daily for months 2–6, 100 μg twice daily for months 7–18); (2) budesonide, identical treatment to group 1 during months 1–6, then budesonide for exacerbations as needed for months 7–18; and (3) disodium cromoglycate (DSCG) 10 mg three times daily for months 1–18. Exacerbations were treated with budesonide 400 μg twice daily for 2 weeks.Main outcome measures:Lung function, the number of exacerbations and growth.Results:Compared with DSCG the initial regular budesonide treatment resulted in a significantly improved lung function, fewer exacerbations and a small but significant decline in growth velocity. After 18 months, however, the lung function improvements did not differ between the groups. During months 7–18, patients receiving continuous budesonide treatment had significantly fewer exacerbations (mean 0.97), compared with 1.69 in group 2 and 1.58 in group 3. The number of asthma-free days did not differ between regular and intermittent budesonide treatment. Growth velocity was normalised during continuous low-dose budesonide and budesonide therapy given as needed. The latter was associated with catch-up growth.Conclusions:Regular use of budesonide afforded better asthma control but had a more systemic effect than did use of budesonide as needed. The dose of ICS could be reduced as soon as asthma is controlled. Some children do not seem to need continuous ICS treatment.

Confirmed exposure to water damage was associated with an increase in symptoms. Exposure to water damage caused a significant change in the cellular composition in BAL fluid (lymphocytosis) and blood (decrease of CD19 cells). The depletion of CD19 leucocytes in peripheral blood may indicate an active immune response in the lungs.

ABSTRACT:In adults, asthma treatment with high doses of inhaled corticosteroids has resulted in dermal thinning. The aim of this study was to investigate the skin thickness in children with asthma during budesonide treatment. In a double-blind study, 113 children, 5-10 y old, with persistent asthma received budesonide 400 g twice daily for 1 mo and thereafter 200 g twice daily for 5 mo. Thereafter, 56 children received 100 g twice daily for 1 y, whereas 57 other children used budesonide periodically for exacerbations. An additional 54 children were treated with disodium cromoglycate (DSCG) for 18 mo. Skin thickness was measured on each forearm before and after treatment for 6, 12, and 18 mo using a 20-MHz high-resolution ultrasonic device. The initial 6-mo budesonide treatment resulted in a greater reduction in mean skin thickness in the forearms compared with DSCG (right: Ϫ35.9 versus Ϫ5.9 m; p ϭ 0.004; left: Ϫ30.6 versus Ϫ7.3 m; p ϭ 0.03). At month 18, the inter-group differences were no longer significant. Budesonide inhalations in daily doses of 400 -800 g in prepubertal children with newly detected asthma may cause minor dermal thinning. The changes were reversible during low dose or periodic treatment with budesonide. (Pediatr Res 67: 221-225, 2010)
