I am really going to ask you to cite your sources on the fact that autoimmune diseases are caused by sterile environment. I remember reading that people of european descent have increased odds of certain autoimmune afflictions because of the black plague [1] and also on the wikipedia page it mentions that autoimmune diseases are triggered by infection [2], not LACK of it. [1] I failed to find a source for this though, so if someone can point me out if I'm right or wrong, please do so.
