Describe the difference between anaphylaxis and anaphylactoid:
Anaphylaxis is an immediate systemic reaction caused by rapid IgE-mediated immune release of potent mediators from tissue mast cells and peripheral blood basophils.
Anaphylactoid reactions are immediate systemic reactions that mimix anaphylaxis but are not caused by IgE-mediated immune responses.
