Portuguese experts reached consensus on optimizing oral corticosteroid (OCS) use in severe asthma. Key recommendations include risk assessment for OCS in exacerbations and prioritizing biological agents for eligible patients.
Area of Science:
- Pulmonology
- Allergology
- Clinical Practice Guidelines
Background:
- Severe asthma management requires optimized use of oral corticosteroids (OCS).
- A national consensus is needed to guide OCS therapy in Portugal.
- Understanding expert opinion is crucial for updating clinical guidelines.
Purpose of the Study:
- To establish a national consensus on the optimal use of oral corticosteroids (OCS) for severe asthma in Portugal.
- To identify expert agreement on therapeutic strategies, safety, and monitoring related to OCS.
Main Methods:
- A modified 3-round Delphi method involving 65 statements was employed.
- Online surveys and a face-to-face meeting were used to gather expert opinions.
- Consensus was defined as ≥90% agreement in round one and ≥85% in subsequent rounds.
Main Results:
- Forty-eight specialists participated, reaching consensus on most statements.
- A significant majority agreed on the need for OCS risk assessment in exacerbations and favorable perception of biological agents.
- Experts prioritized lung function preservation over symptom control when reducing OCS, and monitoring comorbidities was deemed imperative.
Conclusions:
- The findings provide a basis for updating severe asthma management guidelines in Portugal.
- Further research on therapy access, patient adherence, and cost-effectiveness is recommended.
- This consensus aims to improve OCS utilization and patient outcomes in severe asthma.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

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...
