Churg Strauss vasculitis (CSV) is an extremely rare disease that results from inflammation of the blood vessels and causes injury to many organ systems. Vasculitis means inflammation of blood vessels and CSV may damage small and medium-sized blood vessels. CSV also is known as Churg Strauss syndrome, allergic angiitis, and granulomatosis.
The areas most commonly involved are the nose, sinuses, lungs, heart, intestines, and nerves. In about one-half to two-thirds of people with CSV, inflammation also may affect the kidneys, muscles, or joints.
NSAIDs -- or nonsteroidal anti-inflammatory drugs -- are commonly used to treat rheumatoid arthritis (RA). NSAIDs help manage the chronic pain, inflammation, and swelling associated with RA.
NSAIDs do not slow RA progression. NSAIDs are usually used along with other RA medications, such as methotrexate or biologics. These more potent drugs also help prevent further joint damage.
CSV is distinguished from other types of vasculitis because people with CSV often have asthma and/or have an increased number of so-called allergic type blood cells called "eosinophils."
What Are the Symptoms of Churg Strauss Vasculitis?
Because many different organ systems may be involved, many different symptoms are possible. People who have CSV may feel: generally ill, have fevers, shortness of breath, cough, wheezing, increased nasal discharge, facial pain from sinusitis, rashes, abdominal pain, blood in the stools, or muscle and joint pain (arthritis).
CSV in the nerves may cause an abnormal sensation called paresthesia, which involves a burning or prickling sensation in the limbs and other parts of the body, followed by loss of sensation or loss of strength. Any combination of these symptoms may be present.
Who Gets Churg Strauss Vasculitis?
CSV can affect people of all ages, from children to the elderly. The average age of people with CSV at diagnosis is about 35 to 45 years old.
What Causes Churg Strauss Vasculitis?
Although allergies have been thought to play a role in the development of CSV in some people, the exact cause is unknown.
How Is Churg Strauss Vasculitis Diagnosed?
The diagnosis of CSV is based on a combination of factors, including:
Complete medical history and physical exam to exclude other illnesses that may have similar symptoms
Presence of typical CSV symptoms, especially the presence of asthma, the most constant feature of CSV.
Blood tests that indicate abnormal blood counts, often with an increased number of eosinophils
X-rays that show tissue damage or inflammation in areas such as the lungs or sinuses
Urinalysis, which may indicate excessive protein or an abnormally high number of red blood cells
