I have never actually been diagnosed yet with Lupus, but all the symptoms are there just not the positive ANA, but I do have vasculitis, Microscopic Polyangitis is the form I have, and it has come out of remission again. I was first treated in December of 2008 with low dose Cytoxan (a chemo drug) by infusion once a month for 6 months. My rheumy wants to use a new drug called Rituxan this time which has some really scary side effects but in doing my research I learned it is for severe cases of my vasculitis when it causes lung and kidney problems. I do not know that I have that yet, and was wondering what I would look for? I am waiting for an opening to see my Neuro for her opinion and to ask some more questions. So I thought I would turn here to see if any of you could help.
