Polyarteritis
Polyarteritis
Polyarteritis (pronunciation: /ˌpɒliːɑːrtəˈraɪtɪs/) is a serious blood vessel disease where small and medium-sized arteries become swollen and damaged when they are attacked by rogue immune cells.
Etymology
The term "Polyarteritis" is derived from the Greek words "poly" meaning many, "arteria" referring to arteries, and "itis" indicating inflammation. Thus, it refers to the inflammation of many arteries.
Symptoms
Symptoms of polyarteritis can vary greatly from person to person, and depend on which arteries are affected. Common symptoms include fatigue, weight loss, muscle and joint aches, and a rash or skin sores. More severe symptoms can include nerve damage, kidney failure, and heart attack.
Causes
The exact cause of polyarteritis is unknown, but it is thought to be an autoimmune disease, where the body's immune system mistakenly attacks its own cells and tissues. It is not contagious and does not seem to run in families.
Diagnosis
Diagnosis of polyarteritis often involves a combination of physical examination, medical history, blood tests, and imaging studies such as MRI or CT scan. A biopsy of affected tissue may also be performed.
Treatment
Treatment for polyarteritis typically involves medications to suppress the immune system and reduce inflammation, such as corticosteroids and immunosuppressive drugs. In severe cases, surgery may be needed to repair or bypass damaged arteries.
