title: Outcomes after renal transplantation for FSGS in children.
abstract: Focal segmental glomerulosclerosis (FSGS) is the primary diagnosis resulting in end-stage renal disease in approximately 12% of children receiving renal transplantation. Recurrent FSGS after transplantation is unpredictable and clear risk factors have not been identified. Post-transplantation, the incidence of acute tubular necrosis requiring dialysis is higher in children with FSGS compared with other diagnoses and may represent immediate severe recurrence. Graft survival is decreased in children with FSGS compared with other primary diagnoses, and the impact is greatest in recipients of living donor transplants. Graft loss caused by recurrent FSGS is significantly higher in living donor transplants compared with cadaveric donor transplants in children. Compared with adults, the impact of FSGS on graft survival appears to be greatest in children. White recipient race is associated with a higher risk of graft loss from recurrent FSGS. Efforts to elucidate the mechanisms of recurrent FSGS and to understand risk factors based on genetics, potential circulating cytokines and permeability factors, age and race must move forward before we can significantly impact outcomes in renal transplantation for FSGS.
