Conclusions
• Renal transplantation is associated with a
survival advantage
• This survival advantage over maintenance
dialysis is maintained even when marginal
kidneys are used for transplantation
• Waiting time on dialysis is associated with an
increased risk for graft loss and patient death
after renal transplantation
Incompatible Renal
Transplantation
or
High Risk Transplantation
High Risk Renal Transplantation
• Demographic : Child or age>60, African American
• Medical : Diabetic, Uncontrolled BP, cardiac problems,
High BMI, + Viral infections, Sickle cell disease
• Surgical : Major abdominal surgery, access, vascular
• Psychosocial : Noncompliance, Lack of family support,
Lack of insurance, alcohol/substance abuse
• Allograft : Imported, DCD or ECD
• Immunologic :High PRA, Sensitizing events, Incompatible
Blood group
Incompatible Renal Transplantation
• ABO Blood Group Incompatible
• HLA (Cross Match) Incompatible
Blood Group: ABO
• O : Universal donor can receive only O or A2
• A : Can receive from A or O
• B: Can receive from B or O
• AB : Universal recipient, Can receive from
A,B,AB or O
Facts
• It is possible that blood group
antigens may be shared by some
bacteria, leaves and seeds of plants.
• Infants have low levels and older
patients have higher levels due to this
exposure.

Introduction
“Drugs don’t work
in patients who don’t take them”
-C. Everett Koop, M.D.
• Non-adherence to transplant medications
– Important and leading cause of transplant
failure
Gaston RS, Hudson SL, Ward M, Jones P, Macon R. Late renal
allograft loss: noncompliance masquerading as chronic rejection.
Transplantation Proceedings. 1999;31(4, Supplement 1):21S-23S.
– Precedes over 1/3 of transplant failures
Butler JA, Roderick P, Mullee M, Mason JC, Peveler RC. Frequency
and impact of nonadherence to immunosuppressants after renal
transplantation: a systematic review. Transplantation. 2004;77(5):769776.
Non-adherence in general nephrology
• Hemodialysis
Newmann JM, Litchfield WE. Adequacy of dialysis: the patient's role and
patient concerns. Semin Nephrol. 2005;25(2):112-9.
Hecking E, Bragg-Gresham JL, Rayner HC, et al. Haemodialysis
prescription, adherence and nutritional indicators in five European
countries: results from the Dialysis Outcomes and Practice Patterns Study
(DOPPS). Nephrol Dial Transplant. 2004;19(1):100-7.
• Peritoneal dialysis

measured by supply inventories during home visits. Am J Kidney Dis.

–
ESRD due to HTN
s/p deceased donor renal transplant 5/2002
Creatinine 0.8 in 2004
Recent serum Cr in 2.5-3.0 range
Transplant biopsy spring 2005
• Moderate chronic allograft nephropathy
• Immunosuppressive regimen
– Prednisone
– Cyclosporine (Neoral)
– Mycophenolate mofetil (Cellcept)
Case (continued)
• On emergency visit to transplant clinic,
– Complained of SOB and DOE for past week
– Ran out of metoprolol several weeks before
– Serum Cr 8.5
• Admitted to Saint Barnabas Medical Center
– Repeat transplant biopsy
• Severe chronic allograft nephropathy
• Acute cellular rejection, grade 1B
– Treated with high-dose corticosteroids
– Upon further questioning, patient admitted
• Not taking prednisone for past several months
• Not taking mycophenolate mofetil for past 3 weeks
– Awaiting mail delivery of prescriptions
Case (continued)
• Hospital course
– Started on hemodialysis for uremic symptoms
– Immunosuppressive medications changed
• Cyclosporine replaced with tacrolimus
– When dialysis held, transplant failed to show
any function
• Patient returned to maintenance dialysis
Profiles of non-adherent
patients
Greenstein S, Siegal B. Compliance and noncompliance in patients with a
functioning renal transplant: a multicenter study. Transplantation.
1998;66(12):1718-26.
• “Accidental” non-compliers
– Disorganized
– Medication ingestion is not a priority
• “Invulnerables”
– Believe that they do not need to take their
immunosuppressive medications regularly
• “Decisive” noncompliers
– Independent rationales for non-adherence
Reasons for non-adherence:
Complexity of treatment regimen
• Increased dosing frequency
– Leads to decreased adherence
Claxton AJ, Cramer J, Pierce C. A
systematic review of the associations
between dose regimens and
medication compliance. Clin Ther.
2001;23:1296-310.
Reasons for non-adherence:
Side effects of medicines
• Medication side effects are under-recognized by
transplant professionals
Peters TG, Spinola KN, West JC, Aeder MI, Danovitch GM, Klintmalm GB, et al.
Differences in patient and transplant professional perceptions of immunosuppressioninduced cosmetic side effects. Transplantation. 2004;78:537-43.
• Cosmetic changes
– Important cause of non-adherence among adolescents
and young adults
Prevalence of non-adherence
• 22% of transplant recipients were non-adherent
• Median of 36.4% of graft losses are associated
with prior non-adherence
• Probably underestimates the actual incidence
Interventions to increase
adherence
Osterberg L, Blaschke T. Adherence to medication. N Engl J Med.
2005;353:487-97.
• Patient education
• Improved dosing schedules
• Improved communication between
physicians and patients

SBHCS Protocol :
Immunosuppression
•
Thymoglobulin 6 mg/kg over 3-4 days starting intra op
•
Solumedrol 500 mg pre-op, then 250 mg bid post-op day 1, 125 mg
bid post op day 2 and 60 mg bid post op day 3
•
Tacrolimus:Trough levels 10 for 90 days, 8-10 until 365 days,5-8
after 365 days
•
Mycophenolate Mofetil 1 gram bid
•
In Sirolimus arm : Levels 10 for 90 days, 5-8 until 365 days and 5
thereafter.
•
Suspected ACR: Biopsy and treatment with Thymoglobulin, no
steroids
•
Prophylaxis: Bactrim DS, Mycelex, Valcyte
