What Is EGPA? Everything Patients Need to Know Eosinophilic Granulomatosis with Polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is an ultra-rare, chronic autoimmune disease that causes severe inflammation of the small to medium-sized blood vessels (vasculitis). If you or a loved one has recently been diagnosed, understanding this multi-system disorder is the first step toward effectively managing symptoms and preventing long-term organ damage.
While there is currently no cure, modern medical advancements mean that EGPA is a highly treatable condition, allowing most patients to achieve remission and maintain an excellent quality of life. What Happens to the Body in EGPA?
The root of EGPA lies in a malfunction of the immune system. The body overproduces a specific type of white blood cell called an eosinophil.
Eosinophil Excess: Normally, eosinophils help fight off allergies or parasites. In EGPA patients, they flood the bloodstream and healthy tissues, causing widespread inflammation.
Blood Vessel Inflammation: This inflammation restricts blood flow to vital organs and tissues.
Granulomas: Over time, clusters of inflammatory cells form tiny nodules called granulomas, which can further damage tissues. The Three Stages and Common Symptoms
EGPA is notoriously difficult to diagnose because its symptoms mimic more common conditions like everyday asthma. The disease often progresses through three distinct phases, though they do not always occur in a strict sequence: 1. The Allergic Stage
This phase is usually dominated by respiratory issues. Nearly all EGPA patients have asthma, which often develops later in adulthood and is difficult to control. Other early signs include severe sinus pain, nasal polyps, a runny nose, and chronic allergies. What Is EGPA and How Is It Treated? – Health Central
