Regarding your Question about one doctor to cover all the issues related to immune diseases, disorders, etc. i don't think there is anyone like this today that would identify as a one stop shop for autoimmune problems. It may sound crazy to you but what I've been doing over the past few years is experimenting with how low of a dosage my body will tolerate and keep the symtoms at bay. I have CIDP, Rheumatoid, Psoriatic and Osteoarthritis. We have to be vigilant, taking prescription drugs can cause more harm than good. We've heard this before, "the cure is worse than the disease itself." What is key for me is to eat good food and exercise as much as your body can do. I am very blessed to have a physical therapy provider who allows me for a token monthly fee to use their indoor heated saltwater pool for water aerobics. I am double bless as well to have a spouse who drives me to do what I can when I can. Also, I have recently found a acupuncturist / herbalist who I am working with to improve digestion and neuropathy in my feet and hands caused by CIDP. There are good days and there are bad days but each day I try to remind myself that I am a child of God and His plan and will for me is good.
