I don't have any specific autoimmune diagnosis, but I have been having many problems that are common in Sjogren syndrome and other autoimmune disorders.
10 years ago I had Lymphoma (which is more common in some autoimmune disorders), I felt a lot better for a couple of years after the chemotherapy which included Rituximab, so my doctors thought it is worth trying Rituximab again.
