Methylprednisolone therapy for acute asthma in infants and toddlers: a controlled clinical trial

Area of Science:

• Pediatric Emergency Medicine
• Respiratory Medicine
• Clinical Pharmacology

Background:

• Acute asthma exacerbations are a common reason for emergency room visits in infants and toddlers.
• Current treatment guidelines often focus on bronchodilators, with varying recommendations for early corticosteroid use in this age group.

Purpose of the Study:

• To evaluate the efficacy of early combined corticosteroid and beta-adrenergic therapy in reducing hospital admissions for acute asthma in young children.
• To assess treatment outcomes based on age and severity of asthma symptoms.

Main Methods:

• A controlled, double-blind trial involving 74 infants and toddlers (7-54 months) presenting with acute asthma.
• Patients received salbutamol inhalations plus either intramuscular methylprednisolone or a placebo.
• Clinical assessment and admission decisions were made 3 hours post-treatment.

Main Results:

• The corticosteroid group showed a significantly lower admission rate (20%) compared to the placebo group (43%).
• In younger children (6-24 months), steroid treatment markedly reduced admissions (18% vs. 50%).
• While a similar trend was observed in older children (24-54 months), it did not reach statistical significance.

Conclusions:

• Early administration of corticosteroids combined with beta-adrenergic agents is effective in reducing hospital admission rates for acute asthma in infants and toddlers.
• This therapeutic strategy appears particularly beneficial for younger children within the studied age range.
• The findings support the early use of corticosteroids in managing acute pediatric asthma in emergency settings.
