title: A case of living-related renal transplant from the donor with membranous nephropathy.
abstract: BACKGROUND
  When a patient who had renal replacement therapy becomes older, an elder donor candidate may be considered as a potential donor for living-related transplantation. Elder donor candidate might have pre-existing disease including mild renal dysfunction, such as proteinuria. Marginally appropriate donors might be considered for renal graft because of the shortage of donors. A successful outcome after kidney transplantation from a living-related donor diagnosed as membranous nephropathy is reported.
  
  
  METHODS
  A 38-yr-old male had been on continuous ambulatory peritoneal dialysis (CAPD) since the age of 37. His 63-yr-old father had mild proteinuria, and had been diagnosed with membranous nephropathy by needle biopsy at the age of 60. However, renal function of the father was found to be stable for three yr in a preoperative examination for donor; the father had normal renal function except for mild proteinuria. After adequate informed consent, we transplanted a kidney from the father, diagnosed with membranous nephropathy, to his son with a cyclosporine A-based immunosuppression regimen. In both the recipient and the donor, postoperative course was stable without complication such as rejection or infection. At 57 months after transplantation, the serum creatine level was 1.7 mg/dL in the recipient and 1.2 mg/dL in the donor. At 39 months after transplantation, allograft needle biopsy showed mild spike formation with partial thickening of the glomerular basement membrane (GBM). Decreases in electron-dense deposits and electron-lucent washout lesions with thickening of the GBM were observed using electron microscopy. This was diagnosed as Stage IV membranous nephropathy, showing clearance of the immune complexes and histological repair of the GBM.
  
  
  CONCLUSIONS
  Donation of the kidney did not affect the residual renal function of the father with membranous nephropathy. Pre-existing membranous nephropathy itself might show remission after transplantation in the recipient. However, long-term careful observation for both the donor and recipient is required.
