  3. 3. Our Case A 58 year old male with significant CAD, multiple myocardial infarctions, resulting in an ischemic cardiomyopathy & ejection fraction of 15%. The patient’s baseline creatinine was 1.3 mg/dl, but had been persistently elevated between 2.5-3.0 mg/dl. This had been attributed to decompensated heart failure. Past Medical History: Type II diabetes mellitus Essential hypertension
  4. 4. Our Case (cont’d) Urine protein/Cr ratio: 122 mg/G CrCl: 31 ml/min (at a Cr of 3.0 mg/dl) Urine microscopy: bland urinary sediment Renal Ultrasonagraphy: R kidney 11.3 cm L kidney 9.8 cm Normal Echogenicity Cortical atrophy (L > R)
  5. 5. Our Case (cont’d) The patient was considered an appropriate candidate for a heart transplantation. Is the patient a candidate for a kidney transplantation as well? What are the criteria for a dual heart-kidney transplantation? Does our patient meet the criteria for a dual organ transplantation? + versus

  8. 8. Two Schools of Thought Purists Physicians who believe that each organ should have it’s own set of criteria regarding transplantation, & that dual-organ transplant candidates should be evaluated for each organ independently of the other. Liberalists Physicians who believe that in dual-organ transplant candidates, one organ is primary & the other is secondary. All steps should be taken to ensure graft survival of the primary organ, including, if needed, transplantation of the secondary organ.

  15. 15. Why Dual Organ Transplantation? <ul><li>Graft survival (liver) decreases if renal impairment is present </li></ul><ul><li>Renal dysfunction is inevitable with the current immunosuppressive agents used (specifically calcineurin inhibitors) </li></ul><ul><li>Single donor dual organ transplantation is complicated with less immunologic rejection of either organ than multiple donor dual organ transplantation </li></ul>

Why Not Dual Organ Transplantation? <ul><li>Donor kidneys are rare </li></ul><ul><li>Renal dysfunction, if reversible, should not be an indication for dual-organ transplantation </li></ul><ul><li>Renal dysfunction, whose reversibility is unknown, should be quantified and followed over time to determine if permanent renal failure is likely </li></ul>

  28. 28. Why Not Dual Organ Transplantation? <ul><li>Donor kidneys are rare </li></ul><ul><li>Patient survival may not be any better with dual organ transplantation </li></ul><ul><li>Intermediate outcomes, such as rejection and infection rates, may not be better in dual organ recipients </li></ul>
  29. 29. Unanswered Questions <ul><li>Will a patient with renal failure recover function? </li></ul><ul><li>If renal failure is not absolute, is there a way to predict who will recover? </li></ul><ul><li>If renal recovery is possible, to what degree must the kidneys regain function in order to negate the need for a dual transplantation? </li></ul>4) Do patients with dual organ transplants have improvements in any measurable outcome than single organ transplant patients with concomitant renal disease?
  30. 30. Our Case -- Revisited A lengthy discussion between the Transplant Nephrologist, the primary Cardiologist, the patient and his wife was conducted. The Cardiologist explained that the literature supported a dual heart-kidney transplant to improve patient outcomes. He/She suggested a CrCl of 50 ml/min or less as the threshold for dual transplantation.
  31. 31. Our Case -- Revisited The Transplant Nephrologist felt the patient had acute renal failure in the context of chronic kidney disease. However, neither the degree of acute renal failure nor the underlying chronic kidney disease was of sufficient irreversibility or severity (respectively) to warrant a kidney transplant.
  32. 32. The patient was discharged with aggressive medical management.
