Outcome of renal transplantation in fibrillary glomerulonephritis.
Fibrillary glomerulonephritis (FGN) is a rare but progressive glomerular disease usually with end-stage renal disease (ESRD) developing within months or few years following the diagnosis. Little is known about the outcome of renal transplantation in patients with ESRD due to FGN. We report four patients with FGN who received renal allografts. Two patients developed recurrent FGN in their grafts. One patient was diagnosed to have recurrent FGN 9 years post-transplant, and lost his graft 4 years thereafter. Another patient had recurrent disease 2 years post-transplant but has stable graft function after 7 years. One patient died with normal renal allograft function 7 years following transplantation. The fourth patient has chronic transplant nephropathy 34 months post-transplant without evidence of recurrent FGN. A literature review revealed 10 additional patients who received 11 renal allografts due to ESRD caused by FGN. Four of these 10 patients had biopsy-proven recurrence (one patient in two subsequent grafts), but this caused graft loss only in 2 patients 56 months and 7 years post-transplant, respectively. The earliest recurrence was diagnosed 2 years post-transplant. We conclude that although the recurrence rate of FGN in renal transplants is high (around 50%), the recurrent disease has a relatively benign course and prolonged graft survival is possible.
