Phenotype-Guided Asthma Therapy: An Alternative Approach to Guidelines.

Area of Science:

• Pulmonology
• Pharmacology
• Clinical Medicine

Background:

• Asthma management often relies on a stepwise approach using inhaled corticosteroids (ICS).
• Current guidelines may not adequately differentiate ICS potency or consider individual patient inflammatory profiles.
• Existing recommendations might not align treatment strategies with specific patient therapeutic objectives.

Purpose of the Study:

• To critically evaluate current asthma treatment guidelines, particularly the stepwise approach to inhaled corticosteroid (ICS) therapy.
• To highlight limitations in guidelines regarding ICS potency, efficacy, safety, and patient-specific inflammatory profiles.
• To propose an alternative asthma management strategy that incorporates individual patient factors.

Main Methods:

• Review of current asthma treatment guidelines and relevant scientific literature.
• Analysis of the efficacy and safety profiles of different inhaled corticosteroids (ICS).
• Examination of the role of patient inflammatory phenotypes in treatment response.

Main Results:

• Guidelines often overlook significant differences in ICS potency and systemic effects.
• Patient inflammatory profiles (e.g., T2-high inflammation) are not consistently considered, impacting ICS response.
• Current recommendations may not sufficiently address varying therapeutic goals (symptom control vs. exacerbation prevention).

Conclusions:

• A personalized approach to asthma management is needed, moving beyond generic stepwise therapy.
• Treatment decisions should integrate ICS potency, individual inflammatory status, and patient-specific therapeutic objectives.
• This tailored strategy aims to optimize asthma control while minimizing potential side effects of ICS.
