Again, although there is no specific mechanism to link the two, I wonder if the presence of something the body objects to might trigger a quite different problem.
This soap thing. If I go to make tea (with filtered water from a dispenser in the fridge door) and the water shows the slightest tendency to bubble, I sling it and rinse the cup again thoroughly to remove the slightest traces of dishwasher soap that may remain. In my case it is because of a possible link with anaphylaxis, but if traces of soap can cause a life threatening allergic reaction, it's possible that it might trigger something else.
Just Occam's razor again.
I came across this a while back. It's interesting in some ways, but I'm not really sure that it's a useful link.
