Immune Basics
passive
- innate
- you're born with it
-
Immune basics
active
- acquired or adaptive
- you develop it
-
Purpose of vaccines
- trick the body into producing antibodies against a harmless imposter
- then, if the real microbe turns up, the body's defenses are primed to foil infection and disease
-
Why are vaccines administered ??
not to cure or manage disease but to prevent it
-
Immunoglobulins
gamma globulin
imunoglobulin G
Why do we use it ?
to create rapid but temporary immunity because pt was exposed to something
made up of pooled protein from 100's of people so like giving wrong blood
-
Immunoglobulins
assess for:
- prior allergic reaction
- recent or proposed live virus vaccination
- recent or proposed allergy testing (may create false positive)
- pregnancy & lactation (weigh risk vs. benefit)
-

- urticaria
- angioedema
- anaphylactic reactions, although rare, have been reported-keep epinephrine on hand and observe pt closely after injection

gives passive immunity - so chicken pox vaccine will not work
- stay with pt for 20-30 minutes after given

Immunosuppressants: overview
calcineurin inhibitors: cyclosporin (Sandimmune)
glucocorticoids: prednisone
cytotoxics: asathioprine (immuran)
KEY CONCEPT
- any time immunosuppressants are used:
- Pt is at risk for infection because their immune system is blocked from working appropriately !!
- (that is what these drugs do)
-
Immunosuppressants:
calcineurin inhibitors:
cyclosporin (Sandimmune, gengraf, neoral)
assess for:
- pre-existing renal/liver disease
- hypersensitivity
- pregnancy (embryo toxic)/lactation
- presence of known neoplasms (risk to spread the cancer)
- concurrent use of other immunosuppressants
-
Immunosuppressants:
calcineurin inhibitors
adverse reactions
- tremor
