General HIV-Transplant Care Considerations
Pretransplant
 Eligibility: patients must satisfy requirements prior to listing
o Stable on ART x 6 months
o CD4 > 200 x 6 months
o HIV care provided at UNC
o No active infections
 HIV evaluation
o Patients will contact the ID clinic requesting an HIV-Transplant evaluation. They will be
scheduled on a Tuesday or Thursday, and care will be supervised by a designated HIV
physician (presently Drs. Quinlivan and Peppercorn and their fellows). If the patient is currently
followed by the UNC ID clinic, they may continue care with their present physician or the
designated HIV physicians.
o An evaluation of the need to change ART will be made if:
 Regimen consists of a PI + NNRTI (due to unpredictable drug interactions)
 Regimen contains zidovudine or stavudine (due to potential for antagonism with MMF)
o Pre-transplant PK/PD studies of ARVs or immunosuppressants will be considered
o Any special prophylaxis requirements will be established, including TB
o Patients will be assigned to an Enhanced Care nurse
 Nephrology evaluation
o Follow current UNC renal transplant work-up with transplant surgery & nephrology
o Patients to be notified of additional risks and possible difficulties of HIV+ transplantation
Transplant Admission
 Transplant nephrology and the infectious diseases consult service are to be notified immediately after
the patient has agreed to come in for transplant. If transplant surgeon on service has concern over
patient, may contact those services prior to contacting the patient.
o These services will follow the patient throughout their hospital admission, though SRF will
remain as the primary service.
 Admission orders to follow current protocols (labs, physical exam, OR scheduling, etc)
 Medication orders to follow HIV Transplant Protocol
 Anticipated transition from transplant surgery to nephrology/ID care will occur around 1 month posttransplant
Post-Transplant
 Nephrology and HIV care to be continue at UNC
 The patient’s post-transplant coordinator will have primary responsibility for management and
coordination of care.
 The patient’s HIV Enhanced Care nurse will work with their post-transplant coordinator to maintain
communication between the two services. It will be their responsibility to work with the appropriate
attending physicians for patient care.
 Labs to follow current UNC protocols. The transplant coordinator is responsible for contacting
appropriate nephrologist/ID attending with abnormal values and any actions taken. These events are to
recorded in the TransChart Notes section as well (so as to feed into WebCis).
o The ID attending/ Enhanced Care nurse may request additional labs/tests as necessary
 Both transplant nephrology and ID are responsible for updating patient medication lists in WebCis
(ID/nephro) and TransChart (nephro)
 CD4/ RNA testing to be followed by ID:
o within 30 days of transplant (pre-transplant – to be ordered with admission labs if CRT)
o at first post-hospital visit (~~10-14 days)
o with any med changes expected to alter ART levels
o with any major change in health status ( i.e. hospitalizations)
o at 60-90 day intervals for 12m after transplant
o at 90-120 day intervals afterwards if fully suppressed and transplant condition is stable (per HIV
guidelines)

Additional considerations that would require the transplant coordinator to notify the Enhanced Care
nurse:
o Medication changes that may alter ARV concentrations
o Medication changes that may alter immunosuppressant concentrations
o Changes to Immunosuppression
o The ordering of any non-protocol labs/tests (in the event the ID service has additional
requests/considerations)
Kidney Transplant – HIV Protocol
Induction:
Antiproliferative: Patient to receive mycophenolate 1000 mg x 1 dose STAT as soon as case is confirmed.
Steroids: Methylprednisolone 500 mg IVPB x 1 dose STAT – tape to chart for intra-op admin.
IL2-RA: Daclizumab 2 mg/kg (round to nearest 25 mg) IVPB x 1 dose on call (product has 4 hour expiration) –
nurse to call pharmacy when patient is called down to the OR. To be administered intra-op. Repeat dose of
1 mg/kg (round to nearest 25 mg) on POD7.
***Patients are NOT to receive any lymphocyte-depleting induction (thymoglobulin, alemtuzumab, etc) without
consultation between transplant surgery AND infectious diseases.***
Maintenance:
Calcineurin inhibitor: Patient to receive tacrolimus starting on POD1. Initiation may be delayed at the
discretion of the attending on service.
 For patients receiving ARVs containing a PI ± NNRTI, the starting dose will be 1 mg PO once. Repeat
dosing to be based upon goal trough of 8-10 ng/mL. The frequency should NOT exceed twice weekly.
 For patients receiving ARVs with a NNRTI, the starting dose will be 1-2 mg PO BID.
 For patients not on any ARVs, the starting dose will be 0.05 mg/kg PO BID.
 Goal tacrolimus trough concentrations as follows (based upon patient specific parameters):
o Months 0-3: 8-10 ng/mL
o Months 3-12: 6-8 ng/mL
o Months > 12: 5-7 ng/mL
**For patients who require conversion to cyclosporine, use the following dosing considerations. May adjust up
or down based upon clinical situation, however the correlation between tacrolimus and cyclosporine dosing is
not as clear as for patients not on ARVs.:
 For patients receiving ARVs containing a PI ± NNRTI, the starting dose will be 25-50 mg PO twice
daily.
 For patients receiving ARVs with a NNRTI, the starting dose will be 200 – 450 mg PO BID. Use 200
mg PO BID if the patient is on nevirapine; use 250 mg PO BID if the patient is on efavirenz.
 For patients not on any ARVs, the starting dose will be 4 mg/kg PO BID.
 Goal cyclosporine trough concentrations as follows (based upon patient specific parameters):
o Months 0-3: 250-300 ng/mL
o Months 3-12: 150-250 ng/mL
o Months > 12: 100-200 ng/mL
Antiproliferative: Patient to receive mycophenolate mofetil 1000 mg PO BID starting on POD0. Doses may be
adjusted based upon tolerability and clinical judgement.
Steroids: Follow taper provided below. For patients on PI, patients should be monitored closely for increased
steroid side effects and potential adrenal insufficiency during the steroid taper. If this becomes problematic,
consider decreasing the doses and/or slowing the taper down over an extended time interval. For patients on
an NNRTI, they should be monitored closely for signs & symptoms of rejection.

Treatment of Rejection
Treatment of rejection is to be based upon current standard of care, assessing the risk/benefit of any therapies
utilized. The preferred therapy for cellular rejection is steroid therapy; lymphocyte-depleting agents should be
administered only after careful consideration, and discussion between transplant surgery, nephrology, and
infectious diseases. For humoral rejection, the decision to administer rituximab vs IVIG vs plasmapheresis
should be similarly weighed. All patients should receive ID prophylaxis similar to post-transplant standards
regardless of treatment modality used.
General Prophylaxis
GI: Patients not on atazanavir or indinavir are to receive esomeprazole 40 mg PO QHS for stress ulcer
prophylaxis. For patients on these two ARVs, consultation must be made with the ID service to assess
risk/benefit of introducing an H2-antagonist (requires boosting with ritonavir).
CV: Patients are to receive an aspirin 81 mg PO daily starting on POD1.
ID Prophylaxis:
Surgical: Patients to have cefazolin 1 g x 1 dose ordered on-call to the OR. One dose should be given 6-8
hours post-operatively as well. For patients with a penicillin allergy, clindamycin 600 mg IVPB may be used in
place of cefazolin.
PCP: Patients to receive sulfamethoxazole/trimethoprim 800/160 mg PO QMWF. May use dapsone 100 mg
daily if patient has a sulfa allergy. If patient with sulfa allergy & G6PD deficiency, can consider aerosolized
pentamidine 300 mg monthly or atovaquone 1500 mg PO daily. This is to be continued for six months after
transplant or treatment of rejection (including with steroids).
CMV: Prophylaxis as follows:
 Low risk: acyclovir 400 mg PO BID x 3 months
 Intermediate risk: valganciclovir 450 mg PO daily x 3 months
 High risk: valganciclovir 900 mg PO daily x 6 months

Patients with a history of CMV infection are to receive valganciclovir 900 mg PO daily for at least one
month post-transplant or post-treatment of rejection. If these patients’ CD4 count goes < 100 (outside
of the immediate post-transplant or post-rejection period), they are to receive valganciclovir until 6
months after their CD4 count recovers to > 200.
EBV: Patients at high-risk for contracting EBV (donor +/recipient -) to receive ganciclovir 5 mg/kg IV daily
while in the hospital. They are to continue on valganciclovir 900 mg PO daily x 1 year on discharge. This will
take the place of CMV prophylaxis in these patients.
Candidiasis: Patient to receive nystatin 10 mL (1,000,000 units) PO TID while on steroids. If CD4 < 200,
patient is to receive fluconazole 100 mg PO daily.
HIV-specific Prophylaxis:
MAC: Patients to receive azithromycin 1200 mg PO qweek if CD4 ≤ 75. Continue until 6 months after CD4
count is > 100. Patients with a history of MAC infection are to receive azithromycin 600 mg PO daily +
ethambutol 15 mg/kg/day x 1 month post-transplant or post-treatment of rejection. If CD4 ≤ 75 and patient is
not within one month post-transplant or post-rejection period, prophylaxis is to be continued until 6 months
after their CD4 count recovers to > 100. The use of rifabutin may also be continued by the infectious diseases
service.
Cryptococcosis, extrapulmonary: Patients with a history of crypto are to receive fluconazole 200 mg PO daily x
1 month post-transplant or post-treatment of rejection. If these patients have a CD4 count < 200, they are to
receive prophylaxis until 6 months after their CD4 count recovers to > 200.
Histoplasmosis: Patients with a history of histo are to receive itraconazole 200 mg PO BID (take with food) or
fluconazole 400 mg PO daily for the rest of their life.
Toxoplasmosis:
 If IgG + and CD4 count < 200, patients to receive sulfamethoxazole/trimethoprim 800/160 mg PO daily
until six months after CD4 count recovers to > 200.
 In patients with a history of clinical toxo infection, prophylaxis is to be initiated with pyrimethamine 25
mg PO daily + sulfadiazine 100 mg/kg PO daily + leucovorin 25 mg PO daily x 1 month post-transplant
or post-treatment of rejection. If CD4 count < 200, prophylaxis must continue until six months after
CD4 count recovers to > 200. These patients do not need additional PCP coverage.
 In patients with a past infection and a sulfa allergy, prophylaxis is to be pyrimethamine 25 mg PO daily
+ clindamycin 600 mg PO TID. These patients must continue on an additional medication for PCP
prophylaxis.
