Altered Immunity HANDOUT Flashcards
What are the 3 altered immunities that can occur?
- Overreaction: hypersensitivity, as with allergic reactions
- Incompetency: immune deficiency or malignancy as with AIDS
- Autoimmune: loss of ability to recognize self
What are helper T cells
Carries CD4 antigen
Initiates immune response
What are suppressor T cells
Carries CD8 antigen
Stops immune response
T F
Immune function declines with age
True
What are cytotoxic Killer T Cells
Carries CD8 antigen
Attacks malignant cells
Responsible for transplanted organ rejection and grafted tissues.
Antihistamines
Blocks histamine receptors
Relieves symptoms of urticaria and angioedema
Diphenhydramine can be given parenterally or orally.
Epinephrine
Immediate treatment for anaphylaxis
Relieves the vasodilation and bronchoconstriction
Given SC or IV
Bee sting kit carries by ppl with known serious allergies
What does a healthy immune system do?
It identifies antigens and effectively destroys or removes them.
IgG
Most abundant
Activated complement system
Phagocytosis
IgA
Protects against rep, GI,GU Infections
IgM
1st present in bacterial and viral infections
What are the 2 types of immune responses
Antibody- mediated
( B Lymphocytes: ACQUIRED IMMUNITY)
Cell mediated
( T Lymphocytes attack antigens directly and activate B cells
What is cromolyn ( Intal)
Blocked histamine release
Given via inhaler or nasal spray
What types of effects do glucocorticoids have
Both topical and systemic effects
Anti inflammation
What is plasmapheresis
A non. Medicational treatment that remove harmful components in plasma by passing blood through cell separator to remove immune complexes.
