Cards

Term
Primary cell mediator of graft vs. host disease
Definition
T cells
Term
Mechanism of hyperacute rejection and management
Definition
pre-formed antibodies; avoid transplant when crossmatch is positive; emergent retransplant
Term
Mechanism of acute rejection and management
Definition
foreign MHC Ags of graft cells; tx with OKT3, pulse steroids
Term
Histologic appearance of acute rejection
Definition
lymphocitic infiltrate
Term
Mechanism of chronic rejection and management
Definition
gradual loss of blood supply; no treatment
Term
Facet of immune system involved in immunosuppression
Definition
Cell-mediated (which is why viral risk is higher than bacterial and also why there is an increase in CA- skin, leukemia, lymphoma, cervical)
Term
MC viral infection post-transplant and tx
Definition
CMV; gancyclovir
Term
MOA of Azathioprine
Definition
# 6-MP derivative that is a purine analog and acts as an anti-metabolite; effect is decreased DNA synthesis which inhibits T cells
Term
MOA of mycophenolate (cellcept)
Definition
# blocks purine synthesis to decrease T and B cell proliferation
Term
MOA of cyclosporine and main side effect
Definition
inhibits mRNA encoding IL-2, IL-3, IL-4 and INF-gamma
Nephrotoxic, hepatotoxic, HUS, tremors and seizures
Term
MOA of FK506
Definition
Blocks IL-2 expression/production from T cells
Term
MOA of prednisone
Definition
Blocks IL-1 from macrophages
Term
Likely cause of biliary stricture post liver txplant
Definition
ischemia, check hepatic artery flow
Term
MCC of oliguria s/p renal txplant
Definition
ATN
Term
1 year survival s/p cardiac txplant
Definition
84%
Term
1 year survival s/p liver txplant
Definition
70%
Term
Most important MHC gene in recipient/donor matching
Definition
HLA-DR (A and B are also important)
Term
2nd MC malignancy post txplant and management
Definition
# Postransplant lymphoproliferative d/o
# stop immunosuppression; may need chemo and RT
Term
Metabolism and clearance of cyclosporin
Definition
Hepatic metabolism and biliary excretion
Term
MOA of OKT3
Definition
# monoclonal Ab that blocks Ag recognition function of T cells by binding CD3
# interferes with MHC I and II
Term
Mechanism of accelerated rejection and management
Definition

(Occurs < 1 week)

# caused by cytotoxic and helper T cells

# increase immunosuprression, pulse steroids and possible OKT3

Term
MCC of mortality of kidney txplant patients
Definition
Stroke MI
Term
MC complication after kidney transplant and management
Definition
Urine leaks
# Tx is drainage and stenting, many need reoperation
Term
DX and management of renal artery stenosis post-transplant
Definition

# Dx with ultrasound

# PTA with stent

Term
MCC of extrinsic compression on txplaned kidney and management
Definition
# lymphocele
# percutaneous drainage, if that doesn't work- then intraperitoneal marsupialization
Term
Management/work-up for kidney rejection
Definition
# first do ultrasound to r/o vascular problem or ureteral obstruction; Bx may be necessary
# decrease cycolsporin or FK because they are nephrotoxic and pulse steroid
Term
Presentation of kidney rejection
Definition
Increased creatinine
Term
MC cause of death of a living kidney donor
Definition
Fatal PE
Term
MC complication for a living kidney donor
Definition
wound infection
Term
5-year graft survival of kidneys
Definition
70% overal; 65% for cadaveric and 75% for living donor
Term
Contraindications for liver txplant
Definition
current EtOH abuse, acute UC
Term
MC reason for liver txplant
Definition
chronic hepatitis
Term
criteria for emergent liver transplant
Definition
Stage III (stupor) or stage IV (coma)
Term
Management of HBV in patients s/p Liver transplant
Definition
HBIG and lamivudine (protease) inhibitor
Term
Best predictor of 1-year survival in liver transplant
Definition
APACHE score
Term
MC complication after liver transplant and management
Definition
# bile leak
# PTC tube and stent
Term
#1 cause of early mortality s/p lung txplant
Definition
reperfusion injury
Term
Histologic appearance of chronic rejection of lung txplant
Definition
bronchiolitis obliterans
