Can anaphylaxis cause liver damage in humans?

If really severe: Anaphylaxis is the most severe type of allergic reaction. If the reaction is so severe that blood supply does not reach vital organs including brain, heart, liver etc, there can be damage. This type of severe reaction would include loss of consciousness, collapse, shock, convulsions, incontinence, etc. Thankfully, most mild-moderate anaphylactic reactions will not result in permanent damage.
