Insights
Low-dose inhaled corticosteroids demonstrated the strongest effect on asthma control, lung function, and bronchial hyper-reactivity in children with dust mite allergy. Triamcinolone, montelukast, and nedocromil all improved symptoms, but inhaled steroids were most effective.
Area of Science:
- Pediatric Pulmonology
- Allergy and Immunology
- Pharmacology
Background:
- Asthma severity is assessed by symptoms, lung function, and medication needs.
- Children with mild to moderate asthma often have allergic triggers like dust mites.
- Comparing different asthma medications is crucial for effective treatment strategies.
Purpose of the Study:
- To compare the efficacy of triamcinolone acetonide, montelukast, and nedocromil in children with dust mite-allergic asthma.
- To evaluate the impact of these monotherapies on asthma control, lung function, blood eosinophils, and bronchial hyper-reactivity.
Main Methods:
- A 3-arm, randomized pragmatic trial involving 256 children (aged 6-18) with mild to moderate asthma.
- Participants received 4 weeks of monotherapy: low-dose inhaled triamcinolone acetonide (400 mcg/day), inhaled nedocromil, or montelukast sodium.
- Outcomes measured included asthma symptom scores, forced expiratory volume in 1 second (FEV1), PC20H (bronchial hyper-reactivity), and serum eosinophil counts.
Main Results:
- Triamcinolone and montelukast significantly improved FEV1 and PC20H, while reducing symptom scores and eosinophil counts after 4 weeks.
- Triamcinolone showed a stronger effect on PC20H compared to montelukast.
- All three drugs reduced daytime and nighttime asthma symptoms and beta-agonist use, with inhaled steroids (triamcinolone) exhibiting the most significant impact.
Conclusions:
- Low-dose inhaled corticosteroids (triamcinolone) demonstrated superior efficacy over montelukast and nedocromil in improving clinical symptoms, lung function, bronchial hyper-reactivity, and eosinophil counts in children with dust mite-allergic asthma.
- Montelukast also showed significant benefits, while nedocromil provided moderate improvements.
- Inhaled steroids are the most effective option for managing mild to moderate allergic asthma in this pediatric population.
Abstract:
Asthma severity can be judged by measurements of symptoms, lung function, and medication requirements. The objective was to compare the effect of a 4-wk monotherapy with low-dose triamcinolone, montelukast and nedocromil on asthma control, lung function, eosinophil blood count, and bronchial hyper-reactivity in children with mild to moderate asthma allergic to dust mite. Two hundred fifty-six children, aged 6-18 yr, with mild to moderate asthma, participated in an 8-wk study. This was a three-arm, randomized no blinding or placebo pragmatic trial comparing the effect of triamcinolone acetonide (400 microg/day), inhaled nedocromil and montelukast sodium on clinical parameters of asthma [score, forced expiratory volume in 1 s (FEV(1))], PC20H, and eosinophil blood count. Two hundred forty-six children completed the study. After 4 wk of treatment with triamcinolone and montelukast, FEV(1) and PC20H significantly increased, and mean total symptoms score and mean number of eosinophil count in serum significantly decreased. Triamcinolone had a stronger effect on PC20H than montelukast. Nedocromil improved total asthma symptoms score and lung function. There was a reduction in the daytime and night-time symptom scores after treatment with all three drugs. Triamcinolone and montelukast had a stronger effect on asthma symptoms than nedocromil. There were statistically significant differences in reduction of nocturnal asthma symptoms between the triamcinolone and nedocromil groups (p < 0.001) and between montelukast and nedocromil (p = 0.001) groups, but not between the triamcinolone and montelukast groups. There was a reduction in beta-agonists use after treatment with all three drugs, with the strongest effect of triamcinolone. The study showed the strongest effect of low-dose inhaled steroids on clinical symptoms, lung function, bronchial hyper-reactivity and eosinophil blood count when compared to other asthma medications.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
