Nebulised sodium cromoglycate in recurrently wheezy preschool children

Area of Science:

• Pediatric Pulmonology
• Allergy and Immunology
• Clinical Pharmacology

Background:

• Childhood asthma, particularly in preschool years, presents significant management challenges.
• Severe pediatric asthma necessitates effective prophylactic treatments.
• Previous treatments may have failed in certain severe pediatric asthma cases.

Purpose of the Study:

• To evaluate the efficacy of nebulized sodium cromoglycate in preschool children with severe asthma.
• To assess the impact of sodium cromoglycate on daily symptoms and overall asthma severity.
• To determine if nebulized sodium cromoglycate affects hospitalization rates or response to infections.

Main Methods:

• A one-year, double-blind, crossover study involving 27 preschool children with severe asthma.
• Treatment involved nebulized sodium cromoglycate (20 mg, four times daily) versus placebo.
• Data collected via daily diary cards and clinical examinations, analyzed for treatment and seasonal effects.

Main Results:

• Significant improvements were observed in night cough, daytime activity, symptom-free days, and overall asthma severity with sodium cromoglycate.
• No significant reduction in hospital admissions or use of intravenous medications was noted.
• Wheeze scores post-upper respiratory tract infection did not improve with sodium cromoglycate treatment.

Conclusions:

• Nebulized sodium cromoglycate offers benefits for symptom control in young asthmatic children.
• It is considered a useful prophylactic option when other treatments have been unsuccessful.
• The treatment regimen is demanding for young children, suggesting a need for adherence support.
