Organ Transplant Flashcards
________ is the only absolute contraindication to organ donation
A positive HIV status
Transplant rejection can happen in 3 ways:
hyperacute, acute, and chronic rejection
Hyperacute rejection is a ______that occurs within minutes of reestablishing blood supply to the organ
vascular thrombosis
Cause of hyperacute rejection
preformed antibodies
How to prevent hyperacute rejection
It is prevented by ABO matching and lymphocytotoxic crossmatch, and thus it is not seen clinically.
__________ occurs after the first 5 days, and usually within the first 3 months
Acute rejection (most common)
Thus, the first goal when liver function deteriorates posttransplant (rising g-glutamyltransferase [GGT], alkaline phosphatase, and bilirubin) is____________
to rule out biliary obstruction by U/S and vascular thrombosis by Doppler
The first line of therapy for acute rejection is
_______
steroid boluses.
If unsuccessful with steroids, ________have been used though their high toxicity is a problem. Newer anti-thymocyte serum is tolerated better
antilymphocyte agents (OKT3)
__________ is seen years after the transplant, with gradual, insidious loss of organ
function. It is poorly understood and irreversible.
Chronic rejection
