Anaphylatic reactions are caused by a massive release of histamine which is
triggered by IgE antibodies.  IgE antibodies are involved in all true
allergies but are not involved in Celiac Disease.  Although people with CD
seem to suffer a higher incidence of allergies than the general population,
these allergies are not directly caused by CD.  An anaphylactic reaction to
a gluten containing product would suggest that the patient has a concurrent
allergy.
