hypersensitivity Flashcards
altered immunologic response to an antigen that results in disease or damage to the host.
hypersensitivity
describe the speed of hypersensitivity reactions
can be immediate (mins to hours) or delayed (several hours to days )
what is the most immediate hypersensitivity reaction, is explosive
anaphylaxis
describe the rate at which anaphylaxis takes place
occurs within minutes of exposure to antigen
what can anaphylaxis lead to
cardiovascular shock and death
what are the common causes for anaphylaxis
beestings, fish and peanuts
what are clinical manifestations of anaphylaxis
itching, pain, swelling, redness, & dyspnea( shortness of breath)
name the following types of immune mechanisms that hypersensitivity is categorized by
type 1, type 2, type 3, and type 4
what is required in order for hypersensitivity to occur
sensitization against a particular antigen that result in primary and secondary immune responses
