Why do you think some rheumatoid md's profiles say they treat autoimmune diseases while others say autoimmunediseases and lupus? do some not like to treat lupus?

Not likely: Lupus or sle is an autoimmune disease. I have not heard of a rheumatologist who did not like to treat lupus.

Lupus Tx: Lupus is the classic autoimmune disease as it can affect many organs through autoimmune inflammation. I have never heard of a rheumatologist who doesn't treat lupus. Maybe some specialize in lupus and advertise that way.
