Rheumatologic Diseases and the Liver.

A variety of rheumatologic disorders may affect the liver. There is a significant epidemiologic, genetic, and immunologic overlap between immune-mediated rheumatologic disorders and autoimmune liver diseases. There is an increased frequency of autoimmune liver diseases, such as primary biliary cholangitis, autoimmune hepatitis, primary sclerosing cholangitis, or overlap syndrome, in patients with systemic lupus erythematosus, rheumatoid arthritis, Sjögren syndrome, systemic sclerosis, vasculitis, and other immune-related diseases. Non-immune-mediated rheumatologic diseases such as gouty arthritis may also have hepatic manifestations. Furthermore, medications used to treat rheumatologic diseases occasionally cause liver dysfunction. Conversely, primary immune-mediated and non-immune-mediated liver disorders may present with rheumatologic manifestations.
