Eosinophilic Asthma Toolkit Gets an Upgrade

People with eosinophilic asthma now can access an improved online toolkit in EosAsthma.org. The updated website helps people get the right diagnosis, understand their condition, and learn about treatment options.

EosAsthma.org was created by Allergy & Asthma Network and the American Partnership for Eosinophilic Disorders (APFED). It is a one-stop website for patients, families, and healthcare professionals.

The resource includes expert-reviewed information, tips for managing symptoms, and many helpful resources. It can benefit patients with eosinophilic asthma, severe eosinophilic asthma and uncontrolled asthma.

What is eosinophilic asthma?

Eosinophilic asthma is a subtype of asthma and chronic lung disease. (The condition is sometimes referred to as eos asthma or e-asthma.) It can be especially challenging to control with traditional asthma medications such as inhaled corticosteroids.

Eosinophilic asthma occurs when the body produces high levels of eosinophils, a type of white blood cell. These are found in blood, lung tissue, and mucus coughed up from the airways. This excess leads to persistent airway inflammation and more severe symptoms. It can also affect lung function and the immune system.

In the United States, an estimated 28.2 million people live with asthma, and 5–10% have severe asthma. Studies show that high eosinophil levels are closely linked to more frequent and more severe asthma attacks. This highlights the importance of early diagnosis and targeted treatment.

Spotlight on biologic therapies

A key focus of EosAsthma.org is educating patients and caregivers about biologic therapies. These are advanced medications that have reshaped the treatment landscape for eosinophilic disorders.

Biologic therapies target specific cell pathways that drive inflammation in the airways. They stop symptoms before they can start, helping prevent asthma attacks and improve long-term control.

It’s essential that patients with severe asthma and their caregivers have a clear understanding of the disease. They can work together with their doctor to control asthma symptoms and identify the right treatment.

Trusted, educational resource for patients and caregivers

The eos asthma toolkit empowers eosinophilic asthma patients to make informed decisions about their care. Severe asthma specialists helped develop and review content and resources to ensure the toolkit is a trusted, guidelines-based source of information.

At EosAsthma.org, visitors can:

• Learn about this severe subtype of asthma.
• Review diagnosis and treatment options, including biologics.
• Explore practical strategies to improve quality of life.
• Identify specialists who treat eosinophilic asthma.
• Read about eos asthma research and clinical trials.
• Find eos asthma resources and connect with communities.

EosAsthma.org was created as part of a grant provided by Sanofi and Regeneron. We are grateful for their support. We are also grateful for medical reviewers who volunteered their time to review the content for accuracy: Purvi Parikh, MD, Marissa Shams, MD, and Michael E. Wechsler, MD, MMSc.
