Churg-Strauss syndrome — also known as allergic granulomatosis (gran-u-loe-muh-TOE-sis) and allergic angiitis (an-je-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 symptoms — and their similarity to symptoms of other disorders — make 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.
