As far as I can tell, autoimmune conditions are not directly inherited. They can just "pop up", so to speak. Or so it seems to me. The only treatment right now for Sjogren's is IvIg and it is slow and probably for the rest of your life-if your veins hold up. And expensive, if you pay out of pocket. There are drugs in the works but of course we need them now. With that in mind, I would like to hear from anyone who has had to stop IvIg. What happened?
