Hypersensitivity DDC Rolainne Flashcards
Allergic reactions
Hypersensitivity
2 types of hypersensitivity
Immediate hypersensitivity reaction
Delayed hypersensitivity reaction
Classification of allergic reaction
Hypersensitivity I
Hypersensitivity II
Hypersensitivity III
Hypersensitivity IV
Also known as anaphylactic reaction
Hypersensitivity type I
what type of reaction is considered immediate type
Hypersensitivity type I and II
Reaction of the body wherein causes circulatory shock and may be fatal. Can be manifested after exposure to an allergen/antigen considered by the body as foregin
Hypersensitivity type I
Food allergen (shrimps)
Hypersensitivity type I
Some medications (ex.penicilin)
Hypersensitivity type I
Pollens, plants (poison ivy)
Hypersensitivity type I
Odors chemicals etc
Hypersensitivity type I
Known as cytotoxic reaction
Hypersensitivity type II
Body mechanism that reacts via its defense mechanism however might cause high mortality if not manage early
Hypersensitivity type II
condition can be manifested as a serum sickness as seen in non compatible transfusion of blood and or its components proteins causes massive cellular hemolysis
Hypersensitivity type II
Causes massive cellular hemolysis
Hypersensitivity type II
These is an immunological reaction where in the body’s antibodies reacts to destroy its own tissue
Hypersensitivity type III
This allergic reaction is considered as delayed type because the bodys 3rd line of defense creates first an antibody towards the material as presented to be an antigen
Hypersensitivity type III
A consequence of post infectious with beta hemolytic streptococci causing acute tonsilo-pharyngitis
Hypersensitivity type III
Known as antibody-antigen rxn
Hypersensitivity type III
It produces a toxin and introduced to the 3rd line of defense in turn it produces antibodies against it but it causes a violent reaction to tissue destruction
Hypersensitivity type III
Tissue destruction
Hypersensitivity type III
Rheumatic heart disease (RHD)
Hypersensitivity type III
Glomerulo nephritis (GN) destruction of kidneys
Hypersensitivity type III
Systemic lupus erythmatusus (SLE)
Myasthenia gravis (MG)
An immune reaction considered also as delayed type of reaction
Hypersensitivity type IV
Graft rejection reaction
Hypersensitivity type IV
The body’s own antibodies reacts to destroy a foreign material which a transplanted material has an identifiable antigen > HLA (human lymphocytic antigen
Hypersensitivity type IV
Recognize by owns antibodies especially immune system “killer cells”
Hypersensitivity type IV
Cytotoxic cells
Lymphocytes (B and T)
Immunoglobulins
Hypersensitivity type IV
Skin, mucus membrane
1st line of defense
Stationed phagocytes
1st line of defense
