Allergic arteritis is a medical term that refers to an inflammation of the blood vessels caused by an allergic reaction. This condition, also known as Churg-Strauss syndrome, can lead to a variety of symptoms, including coughing, asthma, skin rashes, fever, and nerve damage. There are several synonyms for allergic arteritis, including allergic granulomatosis, eosinophilic granulomatosis with polyangiitis, and Churg-Strauss vasculitis. These terms describe the same condition but may be used interchangeably depending on the context. Treatment for allergic arteritis typically involves anti-inflammatory medications and immune system suppressants, and early diagnosis is important for managing the condition and reducing the risk of complications.
