1

Anaphylactic reactions

severe, whole-body reaction after sensitization to an allergen causing a severe allergic response

Anaphylactoid reactions

anaphylaxis-like reaction to a substance without development of IgE antibody that may occur on first exposure to the causative agent

5

Hypersensitivity

allergic reactions that are exaggerated responses by the immune system; produce tissue injury and may cause serious disease
