Lipid panel

Parathyroid hormone

Vitamin D studies

D/C fluconazole

Adjust CNI upwards

PAN T CELL DEPLETING ANTIBODIES

Alemtuzumab

Thymoglobulin

B CELL DEPLETING ANTIBODIES

Rituximab

NON DEPLETING ANTIBODIES

Basiliximab

Daclizumab

COSTIMULATION BLOCKADE

Belatacept

Solumedrol 500mg IV in OR

250mg IV POD 1

100 mgIV POD2

Prednisone 50 mg po POD3

20mg po POD4 – 7

Thymoglobulin 1.5mg/kg IV in OR before revascularization

1.5 mg/kg IV POD 1-6 depending on graft function ( 3 doses for IGF, 5 doses for SGF, 7 doses for DGF)

 Mycophenelate mofetil 500mg po bid (target 1000mg bid)

Prednisone 15 mg po POD 7-14

10 mg po POD14-30

5mg po POD 31, thereafter

 Tacrolimus 0.05 mg/kg every 12 hours starting POD3 or when

Thymoglobulin complete. Target blood level 8-10.

 Mycophenelate mofetil 1000mg po every 12 hours.

Renal dysfunction requiring dialysis

Differential Diagnosis

Acute tubular necrosis

Technical issues (urine leak, vascular thromboses from anastamotic misadventures, etc…)

Antibody mediated rejection, cellular rejection (rare)

Cortical necrosis

 Transplant ultrasound with doppler interrogation

Exclude obstruction, assess for urine leak

Doppler’s assess flow, resistive indices

Renal Scan

Assess radioisotope uptake and excretion

Good uptake, no excretion….ATN

Delayed uptake, no excretion…Rejection, Severe ATN

Percutaneous transplant renal biopsy

 <30% decline of Cr over 3 days

 Differential diagnosis and evaluation basically the same as delayed graft function

 Mid 1990’s, infections exceeded rejection as leading cause for hospital readmission.

 Transplant recipients at increased risk for postoperative bacterial infections

 Lymphocyte depleting induction regimens increased dramatically risk of CMV

 Though uncommon, pneumocystis, other fungal infections potentially catastrophic

 30-60% risk of infection/disease within first 3 months if no prophylaxis

Valcyte 450mg qod to daily for D+/R- for 6 months

Valcyte 450mg qod to daily for D+/- to R+ for 3 months

Acyclovir 400mg tid for D-/R- for 3 months

 If R+ gets infected, 30% comes from recipient, 70% comes from donor

 Valcyte qod dosing for GFR <30, daily dosing for GFR>30

58%Reduction in CMV disease

39% Reduction in CMV infection

37% Reduction in all cause mortality

Decreased risk of herpes simplex, herpes zoster, bacterial infection and protozoal infections

RR 1.6 for acute rejection with CMV infection

RR2.5 for acute rejection with CMV disease

OR 1.5 for arrythmia, CHF, coronary occlusion with CMV disease

OR 4.0 for post transplant diabetes with CMV infection

Low risk of fungal infection within first 3 months

Candida, Histoplasmosis, Aspergillosis, Toxoplasmosis most common in this area

Fluconazole 100mg daily until GFR>30, then 200mg daily

Give for 3 months

Adjust calcineurin inhibitor with discontinuation

 Some centers do not provide

Low risk

TMP/SMX SS daily for 6 months, then Tu/Th until 1 year

Dapsone 25mg daily for one year if sulfa allergic
