Summary
Theophylline is crucial for severe asthma patients unresponsive to other treatments. Removing it led to steroid increases and exacerbations, proving its benefit in this subset.
Area of Science:
- Pulmonology
- Clinical Pharmacology
Background:
- Severe asthma management often involves multiple medications.
- Theophylline's role is debated due to side-effect concerns.
- Reducing systemic steroid use is a key treatment goal.
Purpose of the Study:
- To determine if theophylline can be removed from the regimen of severe asthmatics.
- To assess the impact of theophylline withdrawal on clinical stability and steroid requirements.
Main Methods:
- A double-blind, cross-over trial comparing theophylline and placebo in five severe asthmatic inpatients (12-15 years old).
- Patients were on maximal therapy including systemic steroids and inhaled medications.
- Outcome measures included symptom scores, need for rescue treatments, steroid dosage, and spirometry.
Main Results:
- All patients required increased steroid dosage during the placebo period.
- Spirometry significantly decreased when theophylline was withdrawn.
- Three patients experienced severe exacerbations without viral triggers upon theophylline discontinuation.
Conclusions:
- Theophylline is beneficial for a specific group of severe asthmatics.
- These patients remain uncontrolled despite comprehensive treatment with other medications.
- Theophylline plays a vital role in maintaining clinical stability for this subset.
