What are some of the treatments for autoimmune diseases?
The primary importance in treating any autoimmune disease is the correction of any major deficiencies. An example would be replacing hormones that are not being produced by the gland, such as thyroxin in autoimmune thyroid disease or insulin in type 1 diabetes. In autoimmune blood disorders, treatment may involve replacing components of the blood by transfusion.
Secondly, the diminishing activity of the immune system must be considered. This requires a delicate balance: controlling the disorder while maintaining the body’s ability to fight disease in general. The drugs most commonly used are corticosteroid drugs. More severe disorders can be treated with other more powerful immunosuppressant drugs, such as methotrexate, cyclophosphamide, and azathioprine. All of these drugs, however, can damage rapidly dividing tissues, such as the bone marrow, and so are used with caution. Intravenous immunoglobulin therapy is used in the treatment of various autoimmune diseases to reduce circulating immune complexes. Some mild forms of rheumatic autoimmune diseases are treated by relieving the symptoms with nonsteroidal anti-inflammatory medications. Drugs that act more specifically on the immune system, for example, by blocking a particular hypersensitivity reaction, are being researched.
