Yes, asthma can be associated with high levels of certain white blood cells, specifically eosinophils.
Asthma and White Blood Cells
Asthma is a chronic respiratory condition that causes inflammation and narrowing of the airways. While many factors can contribute to asthma, certain types are linked to specific immune responses involving white blood cells (WBCs).
Eosinophilic Asthma Explained
According to the provided information, eosinophilic asthma is a type of asthma that is associated with high levels of white blood cells called eosinophils. Eosinophils are a type of granulocyte white blood cell and are part of the immune system. They play a role in fighting off certain infections and are also involved in allergic reactions and inflammation.
In people with eosinophilic asthma, there is an overproduction of eosinophils, which accumulate in the airways and contribute to the inflammation and symptoms of asthma. This specific type of asthma is estimated to affect a significant portion of the asthma population, including some of those with severe asthma.
Why Eosinophils Matter
- Inflammation: High levels of eosinophils in the airways can lead to more severe inflammation, mucus production, and airway narrowing.
- Treatment: Identifying high eosinophil levels helps doctors determine the best treatment approach, as certain medications are more effective for eosinophilic asthma.
- Prevalence: While estimates vary, eosinophilic asthma is a notable subtype. The provided reference indicates that in the U.S., where an estimated 25.7 million people have some form of asthma, 15 percent of those with severe asthma have forms that are difficult to control with standard medications, potentially including eosinophilic asthma.
Therefore, while asthma doesn't cause high levels of all types of white blood cells, it can specifically cause an increase in eosinophils, a key type of WBC, particularly in the case of eosinophilic asthma.
