objective 2.7 Flashcards
distinguish self from
nonself and to protect the body from foreign material
(pathogen, antigens), including cancer
Responsible for rejection of kidney, liver, pancreas, lung and
heart transplants.
́Can also sometimes attack itself, causing autoimmune diseases
or immune-mediated diseases
immune system
re drugs that decrease or prevent an
immune response, thus suppressing the immune system.
́They are used to prevent or treat rejection of transplanted organs
immunosuppressant drugs
what is immunosuppressive therapy used to treat?
Rheumatoid arthritis, systemic lupus erythematosus, Crohn’s
disease, multiple sclerosis (MS), myasthenia gravis, psoriasis, and
other autoimmune conditions
what are the types of transplants?
kidney, heart, liver, lung, pancreas, small
bowel, bone marrow, and cornea
the primary concern and occurs because of an immune
response targeted against the transplanted organ
rejection
inhibit all stages of T-cell activation and are used for
induction, maintenance immunosuppression, and acute rejection
glucocorticoids
Calcineurin inhibits T cells activation of the
immune system
calcineurin inhibitors
inhibit cell proliferation
antimetabolites
inhibit cell proliferation
biologics
what are the indications of immunosuppressants?
́Therapeutic use varies from drug to drug.
́Primarily indicated for the prevention of organ rejection
́mycophenolate mofetil and tacrolimus are indicated for both
prevention of rejection and treatment of organ rejection.
́fingolimod hydrochloride and glatiramer are indicated in a type of
MS known as relapsing-remitting multiple sclerosis
what are the AE of immunosuppressants?
- Significant. See table 50.2
- Place patients at risk for opportunistic infections
- Increase risk of certain cancers
what are the interactions of immunosuppressants?
- Increased risk for drug interactions as those who have undergone transplants are on
immunosuppressant drugs a lifetime, often on combination therapy. - Have narrow therapeutic window therefore drug interactions significant
- Drugs that increase levels of immunosuppressant drugs can cause toxicity
- Drugs that reduce immunosuppressant drug levels can lead to organ rejection
- Grapefruit: increase levels of cyclosporin, tacrolimus and sirolimus
- Foods high in potassium: increase cyclosporin nephrotoxicity
- Blocks T cell proliferation.
- Prophylaxis of organ rejection concurrently with other
immunosuppressant drugs, such as cyclosporine and corticosteroids. - Common adverse effects of liver damage
azathioprine
- Monoclonal antibody used to prevent rejection of transplanted
kidneys. - Generally used as part of a multidrug immunosuppressive regimen
that includes cyclosporine and corticosteroids - Has a tendency to cause the allergy-like reaction known as cytokine
release syndrome
basilizimab
- Used for prevention of organ rejection/bone marrow.
- May be used for other immunological disorders.
- Has a narrow therapeutic range.
- Laboratory monitoring of drug levels to ensure therapeutic
plasma concentrations and to avoid toxicity
