Definition
By Mayo Clinic staffChurg-Strauss syndrome — also known as eosinophilic granulomatosis (gran-u-loe-muh-TOE-sis) with polyangiitis (pol-e-an-jee-I-tis) — is a disorder marked by blood vessel inflammation. This inflammation can restrict blood flow to vital organs and tissues, sometimes permanently damaging them.
Asthma is the most common sign of Churg-Strauss syndrome, but Churg-Strauss syndrome can cause a variety of problems, ranging from hay fever, rash and gastrointestinal bleeding to severe pain and numbness in your hands and feet. The wide range of signs and symptoms and their similarity to those of other disorders makes Churg-Strauss syndrome challenging to diagnose.
Churg-Strauss syndrome is rare and has no cure. But, your doctor can usually help you control symptoms with steroids and other powerful immunosuppressant drugs.
