IgG4-related aortitis is a rare autoimmune disorder that affects the aorta, the largest artery in the body. It is caused by an overproduction of IgG4 antibodies, which can lead to inflammation and thickening of the aortic wall. Symptoms of IgG4-related aortitis include chest pain, shortness of breath, and fatigue. Treatment typically involves corticosteroids and other immunosuppressive medications.

The most common symptoms of IgG4-related aortitis are chest pain, abdominal pain, and back pain. Other symptoms may include fever, fatigue, weight loss, and difficulty breathing. In some cases, IgG4-related aortitis can cause aneurysms or blockages in the aorta, which can lead to serious complications.

The exact cause of IgG4-related aortitis is unknown. However, it is believed to be an autoimmune disorder, meaning that the body’s immune system mistakenly attacks healthy tissue. It is also thought to be related to other autoimmune disorders, such as rheumatoid arthritis and systemic lupus erythematosus. Other possible causes include genetic predisposition, environmental factors, and infections.

Treatment for IgG4-related aortitis typically involves corticosteroids, such as prednisone, to reduce inflammation and suppress the immune system. Other medications, such as immunosuppressants, may also be prescribed to help control the disease. In some cases, surgery may be necessary to repair any damage to the aorta.

1. Age: IgG4-related aortitis is more common in people over the age of 50.

2. Gender: Men are more likely to develop IgG4-related aortitis than women.

3. Genetics: Certain genetic mutations may increase the risk of developing IgG4-related aortitis.

4. Autoimmune diseases: People with autoimmune diseases such as rheumatoid arthritis, lupus, and Sjogren’s syndrome are more likely to develop IgG4-related aortitis.

5. Medications: Certain medications, such as corticosteroids, can increase the risk of developing IgG4-related aortitis.

There is no known cure for IgG4-related aortitis. Treatment typically involves medications to reduce inflammation, such as corticosteroids, and medications to suppress the immune system, such as methotrexate or azathioprine. In some cases, surgery may be necessary to repair any damage to the aorta.
