The use of systemic corticosteroids in asthma management in Latin American countries()

The stepwise treatment approach recommended by the Global Initiative for Asthma (GINA) includes systemic corticosteroids (SCS) suggested as a final step if asthma is severe and/or difficult to treat.

Yet, despite the effectiveness of SCS, they are also associated with potentially irreversible adverse outcomes such as type 2 diabetes, adrenal suppression, and cardiovascular disease.

Based on recent data indicating that the risk of developing these conditions can increase after as few as 4 short-term (burst) courses of SCS, even patients with mild asthma who receive SCS occasionally for exacerbations are also at risk of these events.

As a result, recent updates by GINA and the Latin American Thoracic Society recommend decreasing SCS use by optimizing administration of non-SCS therapies and/or increasing the use of alternatives, such as biologic agents.

Recent and ongoing studies characterizing treatment patterns among patients with asthma have revealed alarming trends suggesting the widespread overuse of SCS around the world.

In Latin America, asthma prevalence is approximately 17%, and data suggest that the majority of patients have uncontrolled disease.

In this review, we summarize currently available data on asthma treatment patterns in Latin America, which indicate that SCS are prescribed to 20–40% of patients with asthma considered to be well controlled and over 50% of patients with uncontrolled disease.

We also offer potential strategies to help reduce SCS use for asthma in everyday clinical practice.
