Transplant/ Immunosuppresion Flashcards
What’s an isograft?
Transplanted organs from GENETICALLY IDENTICAL donor (such as identical twin)
What’s an autograft/ autologous transplant/ autologous stem cell transplant?
Is when a tissue is a transplant from 1 site to another on the SAME patient
Most commonly used induction agent?
Basiliximab (interleukin-2 (IL-2) receptor antagonist
What makes up maintenance immunosuppressant therapy?
Calcineurin inhibitor (Tacrolimus is 1st line CNI)
+
Antiproliferative agent (Mycophenolate is 1st line in most protocols), or Everolimus, Sirolimus, Belatacept or Azathioprine
+/-
Steroids (typically prednisone)
Sx of acute rejection?
Flu-like sx - chills, body aches, nausea, cough & SOB
+
Organ-specific sx -
Heart failure sx with heart transplant
Decrease in urine output/fluid retention/ edema/ BP elevation with kidney transplant rejection
Which maintenance drugs have highest nephrotoxicity?
Tacrolimus
Cyclosporine
Which maintenance drugs may worsen DM or cause new onset of DM?
Tacrolimus
Cyclosporine
Steroids
Which maintenance drugs may worsen lipid parameters?
mTor inhibitors
Steroids
Cyclosporine
Which maintenance drugs have highest risk for BP elevations?
Steroids
Cyclosporine
Tacrolimus
Whys other drugs (antiproliferative or antimetabolite) used with CNI?
To reduce nephrotoxicity risk
List infection risks associated with transplant?
Candida: oral and esophageal - oral Clotrimazole lozenges, nystatin or Fluconazole used commonly 1-3 months post-transplant
Cytomegalovirus - Valganciclovir
Herpes simplex - acyclovir, valacyclovir or Famciclovir
Varicella zoster - vaccine prior to transplant
Pneumocystis jirovecii pneumonia -Bactrim for 3-6 mo post-transplant
TB
What should pt self-monitor for when on strong immunosuppressants or with any condition that suppresses the immune system?
Self-monitor for sx of infection -
Fever of 100.5 degree F (38 degree C) Chills Sore throat Ear or sinus pain Cough More sputum or change in color of sputum Pain passing urine Mouth sores Wound that won't heal Anal itching or pain
Infection control in Immunosuppressed pts include:
Air filtration systems
Keeping mouth clean
Keeping away from dusty, crowded areas & sick people
Can live-vaccines be given post-transplant?
No!
Inactivated vaccines only
Pneumococcal vaccine in immunocompromised pts?
In adults >= 19 yrs
PCV 13
PPSV23 - at least 8 wks after PCV 13
List induction agents
Antibodies
- Antithymocyte Globulin (Atgam-Equine; Thymocyte-Rabbit)
Interleukin 2 (IL-2) receptor antagonist - Basiliximab (Simulect)
MOA of anitbodies (induction agent)?
Reverse rejection by binding to antigens on T-lymphocytes (killer cells) and interfering with their function
Drug under antibodies?
Antithymocyte Globulin (Atgam-Equine) (Thymocyte-Rabbit)
Pre-medication necessary with Antithymocyte Globulin (Atgam-Equine) (Thymocyte-Rabbit)?
May be necessary (diphenhydramine, APAP, steroids)
Epinephrine + resuscitation equipment should be nearby
MOA of IL-2 receptor antagonist?
Chimeric (murine/human) monoclonal antibody that inhibits IL-2 receptor on the surface of activated T-lymphocytes preventing cell-mediated allograft rejection
Agents under IL-2 receptor antagonists?
Basiliximab (Simulect)
SEs of Basiliximab (Simulect) - induction agent?
HTN
Fever
Weakness
Stomach upset/n/v/cramping
Peripheral edema
Dyspnea/upper respiratory irritation/infection
Cough
Tremor
Painful urination

Mammalian target of rapamycin (mTOR)- Everolimus (Zortress, Afinitor)
Sirolimus (Rapamune)
Belatacept (Nulojix)
MOA of corticosteroids - Prednisone(maintenance medications)?
Naturally occurring hormones that prevent or suppress inflammation and humoral immune responses
MOA of Antiproliferative Agents (maintenance medications)?
Inhibit T-lymphocyte proliferation by altering purine synthesis
