Hypersensitivity rxns

Type I: Immediate, IgE
Type II: Cytotoxic, IgG/M
Type III Immune complex IgG, M
Type IV: Cell Medidiated

2

Type I Hypersensitivity

Immediate, IgE
Weed, pollen, dust, grass, mold cat or Dog progeins (atopic), hives, utricaria, peanuts, shellfish, bee stings, drugs

3

Tyope II - Cytotoxic

Antibody mediated (no ab/ag complexes)
Hemolytic rxn, goodpastrure's
hyperacute graft rejection

4

Type III Immune complex IgG/M

Serum sickness, SLE, Post Strep Glomerulonephritis, PAN, RA, Arthus rxn, hypersensitive Pneumonitis

22

Pt with sore throat - hematuria _-> Pre-renal azotemia

Antigen-ab rxn (type III)

23

Pt receiving IV abx for endocarditis - pt c/o arthralgias - mechanism of arthralgia is....

immune complex depeostion - serum complement low

24

RAST (radioallergosorbent test

measures IgE in serum (quantitiative immunoglobulins)

25

Skin testing (pin prick test)

more specific and sensitive

26

Pt with rhinitis, occular itching exacerbated by pollen best test?

Pin Prick test

27

Can you do skin testing if pt on anti-histamine

No - reduces sensitivity for 7 days

28

Nursing student started using latex glove for first time and pw hives - best test to confirm?

RAST for allergy to latex

29

Can yo give allergy injections to ABPA?

NO!! will make it worse

30

Can you give allergy injections to prevent contrast dye rxn or hypersensivity pneumonitis

No not IgE mediated....
