Impact of recurrent disease and chronic allograft nephropathy on the long-term allograft outcome in patients with IgA nephropathy.
Although recurrent IgA nephropathy (IgAN) may lead to graft dysfunction after transplantation, donation from living related donor (LRD), with whom the risk of recurrence may be higher, is not a contraindication. Herein, we evaluated the natural history of allograft in recipients with IgAN and the risk factors influencing long-term allograft outcome. Recurrence rate and graft survival were assessed retrospectively in 221 IgAN patients, including transplants from 139 LRDs (62.9%). Ten-year cumulative rate for recurrent IgAN was 30.8%. The operation at younger age and donation from LRD were significant for the recurrence by multivariate analysis. Ten-year graft survival was affected by recurrent IgAN (61.0% in recurrent IgAN group vs. 85.1% in nonrecurrent, P < 0.01). However, transplants from LRDs did not show poor graft survival when compared with those from other types of donors. In transplants from LRDs, the incidence of chronic allograft nephropathy (CAN) was lower than those in grafts from deceased donors (10.8% vs. 19.5%, P < 0.05). When CAN was considered in addition to recurrence, the variance of graft survival was affected significantly by the development of CAN than by the recurrence. These results suggest that the detection and adequate management of CAN could improve graft outcome in transplant recipients with IgAN.
