Types of Hypersensitivity Reactions
type I anaphylactic
:

·
type Il citotoxic
type III
:
Immunocomplex
·
type IV !
delayed hypersensitivity
, type I :
anaphylactic reaction give IM epinephrine
·
most common
excessive inflammation caused by overactive immunity
body's responses are excessive
result from ↑ production of immunoglobulin E (IgE) antibody
acute inflammation occurs when IgE responds to an antigen (pollen) ·
causes
release of histamine (H)
