title: Renal transplantation for end-stage renal disease following bone marrow transplantation: a report of six cases, with and without immunosuppression.
abstract: BACKGROUND. Over 12000 bone marrow transplantations (BMT) are performed in the USA each year. This procedure is associated with significant morbidity including acute and chronic renal failure (CRF). CRF after BMT is usually secondary to radiation nephropathy and,or cyclosporine (CsA) toxicity. Survival on dialysis therapy for patients with radiation nephropathy is poor and renal transplantation may be a preferable form of renal-replacement therapy.
  
  
  METHODS
  We report our experience with renal transplantation in 6 patients with end-stage renal disease (ESRD) following BMT: 4 as a result of radiation nephropathy; one secondary to hemolytic uremic syndrome; and 1 as a result of antitubular basement membrane nephritis. Ages at the time of BMT ranged from 26 to 40 yr. ESRD developed after a mean period of 94 months (range 42-140 months) after BMT. The kidney source was from a living donor in 5 patients, and a cadaveric donor (CAD) in 1 patient. In 3 recipients, the bone marrow and kidney were from the same donor. They are managed without any immunosuppressive therapy. The other 3 were initiated on triple therapy (prednisone, mycophenolate mofetil/azathioprine and cyclosporine/tacrolimus).
  
  
  RESULTS
  These patients have been followed for up to 31 months (range 3-30 months) after kidney transplant, and 5 out of 6 are alive with functioning bone marrow and renal transplants. Their plasma creatinines range from 70 to 160 micromol/L (mean 97 micromol/L). One patient died following metastatic squamous cell cancer of the genital tract.
  
  
  CONCLUSIONS
  1) Renal transplant is a feasible alternative for patients with ESRD following BMT: 2) if bone marrow and kidney are from the same donor, the recipient requires little or no maintenance immunosuppression; 3) short-term results show good survival, but long-term follow-up is needed: 4) infections and malignancy post-renal transplantation were seen in recipients who needed immunosuppression; and 5) reduction in immunosuppression may be needed in such post-BMT patients who undergo kidney transplants.
