About IgG4-related retroperitoneal fibrosis

What is IgG4-related retroperitoneal fibrosis?

IgG4-related retroperitoneal fibrosis is a rare condition characterized by the accumulation of IgG4-positive plasma cells and fibrosis in the retroperitoneal area. It is an autoimmune disorder that can cause abdominal pain, swelling, and difficulty breathing. It is often associated with other autoimmune conditions such as Hashimoto's thyroiditis, Sjogren's syndrome, and inflammatory bowel disease. Treatment typically involves corticosteroids and other immunosuppressive medications.

What are the treatments for IgG4-related retroperitoneal fibrosis?

1. Corticosteroids: Corticosteroids are the mainstay of treatment for IgG4-related retroperitoneal fibrosis. They are used to reduce inflammation and reduce the size of the fibrotic mass.

2. Immunosuppressants: Immunosuppressants such as azathioprine, mycophenolate mofetil, and methotrexate may be used to reduce inflammation and prevent further fibrosis.

3. Surgery: Surgery may be necessary to remove the fibrotic mass if it is causing symptoms or if it is large enough to cause compression of other organs.

4. Radiation therapy: Radiation therapy may be used to reduce the size of the fibrotic mass and reduce inflammation.

5. Biologic agents: Biologic agents such as infliximab and
