Long-term outcomes in kidney transplant recipients with end-stage kidney disease due to anti-glomerular basement membrane disease.

Anti-glomerular basement membrane (GBM) disease causes rapidly progressive glomerulonephritis and end-stage kidney disease (ESKD). Studies of post-transplant outcomes in patients with ESKD due to anti-GBM disease in the United States are lacking. To better characterize outcomes of transplant recipients with a history of anti-GBM disease, we examined patient survival and graft survival among recipients with anti-GBM disease compared with IgA nephropathy at a single center in the United States. We analyzed patient survival, graft survival, disease recurrence, and malignancy rates for kidney transplant recipients with ESKD due to biopsy-proven anti-GBM disease who underwent kidney transplantation at our center between 1994 and 2015. 26 patients with biopsy-proven anti-GBM disease and 314 patients with IgAN underwent kidney transplantation from 1994 to 2015. The incidence of graft loss was 6.2 per 100 person-years for anti-GBM disease, which was similar to IgAN (4.08 per 100 person-years, p = .09). Patient mortality for anti-GBM was 0.03 per 100 person-years, similar to IgAN (0.02 per 100 person-years, p = .12). Disease recurrence occurred in one of the 26 anti-GBM patients. Four out of 26 patients (15%) developed malignancy, most commonly skin cancer. Long-term graft and patient survival for patients with ESKD due to anti-GBM was similar to IgAN after kidney transplantation.
