Transplant Flashcards
(51 cards)
What is an allograft
Transplant from one person to another of the same species
Isograft
Transplant from genetically identical donor
Autograft
Transplant in same patient
What test are used to check for donor compatibility
HLA and ABO blood groups
BBW of using transplant drugs
Infection risk → immunosuppression
Cancer risk → immune system is blunted from suppressing skin cancers
Requires experienced prescribers
What is induction immunosuppression
Given immediately before or after surgery to prevent acute rejection and early post-transplant
Drugs used for induction immunosuppression
No made to treat only for prevention:
Basilixumab
Used for both induction and prevention:
Antithymocyte globulin: Atgam (equine), Thymoglobin (rabbit)
MOA of basilixumab
IL-2 receptor antagonist on the surface of the T lymphocyte
MOA of steroids
Alters the gene transcription of IL2 and other inflammatory cytokines
MOA of antithymocyte globulin
Binds to antigen T-lympocyte and interfere with their function
Drug classes used for maintenance suppression
Calcineurin inhibitor
Antiproliferative
+/- Steroidq
Purpose for prescribing multiple immunosuppressants
Targets multiple mechanisms lowering toxicity risk and reduce skin graft rejection
Types of calcineurin inhibitor
Tacorlimus
Cyclospporine
ADR of Antithyrmocyte Globulin
Anaphylaxis
Infusion-related reactions (premeditate with diphenhydramine, APAP, and steroids)
MOA of CI
Inhibits T-lymphocyte activation by binding to calcineurin
Tacrolimus
Prograf
Cyclosporine
Gengraf, Neoral, Sandimmune
Restasis (Dry eyes)
BBW of cyclosporine
Increased malignancy, infection, nephrotoxicity
Modified and unmodified cyclosporines are not interchangeable
ADR of cyclosporine
↑ BG, hyperlipidemia, hyperkalemia, hypomagnesemia, hyperuricemiam neurotoxicity, nephrotoxcity, gingival hyperplasia
Counseling on cyclosporine
CYP3A4 inhibitor, avoid grapefruit juice
- Don’t use styrofoam cup, mix in glass
- Don’t rinse syringe before or after use
- Non-PVC to prevent leaching of DEHP
- Use compatible diluent and use same diluent
- Administer drink immediately and rinse container with extra diluent to ensure dose is taken
BBW of tacrolimus
↑ malignancy and infection
ADR of tacrolimus
Increased BP, BG, lipids, K, hypomagnesemia, neurotoxicity, alopecia, nephrotoxicity
Counseling of tacrolimus
IV: non-PVC bag
Don’t interchange XL/XR to IR
Food decreases absorption
Take Q12H or once in the morning for XL or XR
MOA of antiproliferative drugs
Inhibits T and B lymphocyte proliferation by inhibiting purine nucleotide synthesis
