Living-related donor transplants should be performed with caution in patients with focal segmental glomerulosclerosis.
The success rates of living-related donor (LRD) transplants are clearly superior to those obtained with cadaver donors. However, caution should be exercised when considering LRD transplantation for a condition which has an increased chance of recurring after transplantation and causing ultimate graft failure. The recurrence rate of focal segmental glomerulosclerosis (FSGS) in the allograft is 20%-40%, with graft failure resulting in 40%-50% of these cases. However, these figures may be an underestimation of the true rate of recurrence of FSGS. Once a first transplant fails due to recurrent disease, the risk of recurrence in the second transplant approaches 80%. Subgroups of patients at high risk for recurrence have been identified. In patients not at high risk for recurrent FSGS, the use of a LRD should be considered, provided that the donor and recipient and their families have been informed that the disease may recur and lead to graft failure. In patients at high risk for recurrence, a LRD transplant should be avoided. Hopefully, future development of a simple and reliable test to predict the likelihood of recurrence will enable us to counsel and advise our patients with FSGS about the wisdom or dangers of proceeding with a LRD transplant.
