Churg-Strauss Syndrome (Eosinophilic Granulomatosis with Polyangiitis)

Churg-Strauss Syndrome, now called Eosinophilic Granulomatosis with Polyangiitis (EGPA), is a rare disease that causes inflammation of small and medium blood vessels. It often begins with asthma and allergic symptoms, then progresses to include high levels of a type of white blood cell called eosinophils. This inflammation can damage organs such as the lungs, skin, nerves, and heart. The exact cause is unknown, but it’s believed to involve immune system dysfunction. Treatment typically includes steroids and immunosuppressive medications to reduce inflammation and prevent organ damage.
