Eosinophilic Asthma (E-Asthma), is a severe form of asthma that affects the entire respiratory system. What sets this type of asthma apart from the asthma you might know, is the high levels of white blood cells called eosinophil. These white blood cells are part of your immune system and help to fight off infection.
High levels of eosinophils can cause inflammation (swelling) that affects the sinuses and nasal passages as well as your lower airways. This kind of asthma is often seen in people who are 25-35 years old.
At this time, we are not sure what causes this type of asthma. Scientists are exploring whether or not there could be a genetic link. What they do know is that this particular kind of asthma is not triggered by an allergen.
Here are some of the symptoms a person might experience with E-Asthma:
- Shortness of breath
- Tightness on the chest
- Stuffy nose
- Chronic sinus infections
- Nasal drainage
- Nasal polyps
- Lost sense of smell
It is important to see your doctor if you are experiencing any of these symptoms. This type of inflammation of your airways can lead to permanent damage to your airways and scarring of the lung tissue.
A doctor will be able to decide if you have E-Asthma by measuring the eosinophils in your blood or saliva and by conducting a bronchial biopsy.
There are injectable medications available to treat E-Asthma along with inhaled corticosteroids: Cinqair, Fasenra, Xolair and Nucala. There is also a new oral medication being tested called Fevipiprant. Though still in development, this experimental drug reduced symptoms and improved lung function in studies completed so far. If Fevipiprant is approved, it would be the first new oral asthma drug to be introduced in 20 years. These treatments take place under the direct supervision of a physician.
