Immune (Transplants) Flashcards
What is a Autologous transplant:
from themselves (stem cells transplants)
4 types of transplants
Autograft: take from one part of body and put it on another (skin, hair, bone)
Allograft: Between members of same species (most common, human-human, kidney, heart, lung, liver)
Isograft: Between identical twins
Xenograft: monkey, pig, cow transplant
What two organs can be partially transplanted
Liver
Lung lobes
Highest demand for _______, ________, _________.
kidneys, hearts, livers
When can a deceased donor donate organs
Usually from brain death. Must have sufficient CV function to perfuse organs
NURSE’S ROLE IN DETERMINING ELIGIBILITY FOR DONATION
follow institution policy to determine if a candidate
contact the local organ donation organization (LifeNet Health)
WE DO NOT TALK TO THE FAMILY ABOUT TOPIC OF ORGAN DONATION
WHAT TESTS ARE DONE TO DETERMINE ELIGIBILITY TO RECEIVE AN ORGAN
HLA: human leukocyte antigen (Helps the immune system distinguish between the body’s own cells and foreign substances)
Antibody panels
ABO compatibility
Assessment for comorbidities
What happens after someone receives a transplant organ
critical care immediately post-op
Must have immunosuppressive drug levels checked to ensure that immunosuppression is therapeutic
Possible organ biopsies after hospitalization (to ensure immune system isn’t breaking it down)
Immunosuppressants start on high dosages that are reduced over time
T/F: You need to be put on immunosuppressants if you receive a autograft
False. Immunosuppression not needed if receiving an autograft
What is the immunosuppressant drug regiment people are put on for solid organs
Triple therapy
Name a Calcineurin Inhibitor commonly used in Triple therapy
Tacrolimus : Inhibit communication with the Tcells to other parts of the immune system
Name a Cytotoxic drug commonly used in Triple therapy
Mycophenolate mofetil: Keeps your T and B cells from replicating
What are the three drugs used in Triple therapy
Calcineurin Inhibitors
Corticosteroids
Cytotoxic drugs
What drug do you expect a transplant patient to be on the rest of their lives?
Corticosteroids
What Sx should you report for a transplant pt
Signs of infection: fever, malaise, flu-like symptoms
Check inflammation: ESR, CRP
Manifestations of rejection: Pain at the site, flu-like symptoms
T/F: A patient on immunosuppressants will have a high or low WBC count?
low WBC
What is hyperacute rejection
Occurs within 24 hours of transplantation
Individual had pre-existing antibodies against the organ
Transplanted organ must be removed
What is acute rejection
Occurs within first 6 months
Can normally be curbed with increase in immunosuppression
Common to have at least 1 bout with rejection
