Abstract

Objective: To determine whether inhaled fluticasone propionate has long-term effects on growth in children with persistent asthma. Study Design: In a double-blind, randomized, parallel-group, multicenter study, 325 prepubescent children with persistent asthma and normal growth rates were treated with placebo or inhaled fluticasone propionate powder 50 μg or 100 μg administered twice daily by a breath-actuated device for 1 year. Growth was evaluated monthly, whereas other safety variables and pulmonary function were evaluated periodically. Results: The prepubescent patients showed no statistically significant differences in mean height, mean growth velocity, or mean skeletal age between any of the treatment groups at any time. Over a period of 1 year, mean height (± SE) increased 6.15 ± 0.17 cm in the placebo group, 5.94 ± 0.16 cm in the fluticasone propionate 50 μg group, and 5.73 ± 0.13 cm in the fluticasone propionate 100 μg group (p = 0.308, overall). Conclusions: Prepubescent children treated with fluticasone propionate 50 μg and 100 μg administered twice daily for 1 year grew at rates similar to placebo-treated control subjects and at rates equal to expected growth velocity for age.

Patient Selection

Children were eligible for the study if they met the American Thoracic Society criteria21 for asthma and had normal growth rates as defined by height measurements (one measurement taken 6 to 18 months before the study and one at screening) between the 5th and 95th centiles and growth velocity between the 10th and 97th centiles (Serono Laboratories, Norwell, Mass.). All height measurements were taken using identical wall-mounted Harpenden stadiometers (manufactured by Holtain, Crymmych, Wales).

Study Population

Three hundred forty-four patients were entered into the single-blind screening period. Nineteen patients were not entered into the double-blind treatment period because of the following factors: abnormal ophthalmic findings (4 patients), unstable asthma (3 patients), use of prohibited concurrent medications (3 patients), failure to meet inclusion or exclusion criteria (2 patients), or miscellaneous reasons (7 patients). Of the remaining 325 patients assigned to use the study drug, 57 showed

Discussion

This is the first prospective, 1-year study evaluating the effects of fluticasone propionate on growth in children. The results of this study demonstrate that long-term administration of inhaled fluticasone propionate 100 μg/day and 200 μg/day is well tolerated in children with persistent asthma. No statistically significant differences were noted between fluticasone propionate and placebo treatment groups with respect to height measurement, growth velocity, or skeletal age. During this study,

      However, the similarity across trials or inadequate reporting prevented such analyses. Three industry-funded trials with high methodological quality (resulting in four dose comparisons) contributed data to the main outcome [3–5]. They pertained to 728 school-aged children measured by stadiometry, who had mild or moderate asthma and were treated with one of three ICS molecules (fluticasone, ciclesonide or mometasone) in whom a dose difference ≤ 150 μg was compared over 52 weeks.

      Finally, the events after drug deposition on the respiratory epithelium, the effect of lung–particle interactions on final dose, and how cell-level mechanisms differ between formulations are under investigation.36 Findings from clinical trials7,28,29 in which several doses of a given inhaled corticosteroid were compared have shown dose-dependent effects on growth, although most trials did not assess more than one dose in children (table) and of the trials that did assess more than one dose, not all doses were shown to significantly affect growth.29 In the CAMP trial18 there were sufficient numbers of patients to analyse dose–response; the results showed a significant daily dose–response association during the first 2 years of treatment, with a 0·1 cm decrement in height for each 1 μg/kg bodyweight increase (p=0·007).
