  34. 6 month kidney survival after biopsy TMA p=0.01

  35. Renal biopsies after non-renal transplantation • most often signs of acute renal failure, pre-existing hypertension and CNI-toxicity • high number of patients with glomerulonephritis • high number of patients with TMA Conclusion 1

  36. Renal biopsies after non-renal transplantation • mostly signs of acute renal failure, pre-existing hypertension and CNI-toxicity • high number of patients with glomerulonephritis • high number of patients with TMA Conclusion 1

  37. Renal biopsies after non-renal transplantation • mostly signs of acute renal failure, pre-existing hypertension and CNI-toxicity • high number of patients with glomerulonephritis • high number of patients with TMA Conclusion 1

  38. Renal biopsies after non-renal transplantation • find early specific lesions • in the advanced stage the extent of IFTA determines renal outcome • extrarenal transplantation may accelerate the process of „aging“ by multifactorial causes Conclusion 2

  39. Renal biopsies after non-renal transplantation • find early specific lesions • in the advanced stage the extent of IFTA determines renal outcome • extrarenal transplantation may accelerate the process of „aging“ by multifactorial causes Conclusion 2

  40. Renal biopsies after non-renal transplantation • find early specific lesions • in the advanced stage the extent of IFTA determines renal outcome • extrarenal transplantation may accelerate the process of „aging“ by multifactorial causes Conclusion 2

  41. Therapeutic consequences • Reduce CNI as much as possible • Finish CNI - mTOR inhibitor combination • Agressive blood pressure control • Plasmapheresis in TMA with HUS • Renal replacement planning
