Severe asthma: approach and management

Area of Science:

• Pulmonology
• Allergy and Immunology

Background:

• Severe asthma presents a significant clinical challenge, often inadequately managed by standard inhaled corticosteroids and bronchodilators.
• Identifying and addressing conditions that mimic or worsen severe asthma is a critical first step in patient care.

Purpose of the Study:

• To outline a rational diagnostic and therapeutic strategy for managing severe asthma.
• To explore alternative pharmacological and non-pharmacological approaches for patients unresponsive to conventional treatments.

Main Methods:

• Review of diagnostic criteria for severe asthma.
• Evaluation of current and emerging pharmacological treatments, including leukotriene modifiers and anti-IgE antibodies.
• Consideration of non-pharmacological interventions and management of confounding variables.

Main Results:

• Accurate diagnosis is paramount, as numerous conditions can present as or exacerbate severe asthma.
• While oral corticosteroids are effective, they carry significant adverse effects.
• Leukotriene modifiers and anti-IgE therapies benefit some patients, but alternative anti-inflammatory drugs and novel modalities are also considered.

Conclusions:

• Despite its complexity, severe asthma can be managed effectively through a systematic diagnostic and therapeutic approach.
• Personalized treatment strategies are essential to improve outcomes for individuals with severe, refractory asthma.
