OBJECTIVES: Recurrent glomerulonephritis can negatively affect kidney allograft survival. However, how primary renal disease affects transplant outcomes in the new era of immunosuppression remains unclear. MATERIALS AND METHODS: We categorized 426 kidney transplant recipients (performed from 1996 to 2007) into 4 disease groups: (1) 99 recipients with biopsy-proven immunologically mediated kidney disease, (2) 40 recipients with urologic disease, (3) 67 recipients with polycystic kidney disease, and (4) 220 recipients with other causes of terminal renal failure/uncertain kidney disease. Long-term transplant outcomes were compared between groups at 1, 5, and 10 years of follow-up. RESULTS: Compared with the urologic, polycystic, and other diseases groups, the immunologic group showed significantly lower time of graft survival (9.5 ± 4 vs 8 ± 4 vs 8.5 ± 4 vs 7 ± 4 years, respectively) and estimated glomerular filtration rate (52.5 ± 32 vs 49 ± 22 vs 50 ± 32 vs 35.5 ± 30 mL/min; P < .05). Relative risk of 10-year graft loss for the immunologic group was 2.8 (95% confidence interval, 1.6-4.9). Recurrence rate was 12% in the immunologic group versus 1% and 0% in the other diseases and remaining groups (P < .05). The relative risk of 10-year graft loss for patients with recurrence was 2.7 (95% confidence interval, 1.2-6.3). Ten-year graft loss rates for patients with biopsy-proven acute rejection, chronic allograft nephropathy, and recurrent glomerulonephritis were 30%, 23%, and 42% (P < .05). For those with biopsy-proven recurrent glomerulonephritis, 10-year estimated glomerular filtration rate was significantly lower than for those with biopsy-proven acute rejection or chronic allograft nephropathy (14 ± 6 vs 18 ± 7 vs 30 ± 10 mL/min; P < .05). CONCLUSIONS: Kidney transplant recipients with immunologically mediated kidney diseases have inferior long-term allograft survival and function versus patients with other causes of renal failure. Recurrence represents the strongest risk factor for premature loss of function and transplant failure.

Abstract
OBJECTIVES: Recurrent glomerulonephritis can negatively affect kidney allograft survival. However, how primary renal disease affects transplant outcomes in the new era of immunosuppression remains unclear. MATERIALS AND METHODS: We categorized 426 kidney transplant recipients (performed from 1996 to 2007) into 4 disease groups: (1) 99 recipients with biopsy-proven immunologically mediated kidney disease, (2) 40 recipients with urologic disease, (3) 67 recipients with polycystic kidney disease, and (4) 220 recipients with other causes of terminal renal failure/uncertain kidney disease. Long-term transplant outcomes were compared between groups at 1, 5, and 10 years of follow-up. RESULTS: Compared with the urologic, polycystic, and other diseases groups, the immunologic group showed significantly lower time of graft survival (9.5 ± 4 vs 8 ± 4 vs 8.5 ± 4 vs 7 ± 4 years, respectively) and estimated glomerular filtration rate (52.5 ± 32 vs 49 ± 22 vs 50 ± 32 vs 35.5 ± 30 mL/min; P < .05). Relative risk of 10-year graft loss for the immunologic group was 2.8 (95% confidence interval, 1.6-4.9). Recurrence rate was 12% in the immunologic group versus 1% and 0% in the other diseases and remaining groups (P < .05). The relative risk of 10-year graft loss for patients with recurrence was 2.7 (95% confidence interval, 1.2-6.3). Ten-year graft loss rates for patients with biopsy-proven acute rejection, chronic allograft nephropathy, and recurrent glomerulonephritis were 30%, 23%, and 42% (P < .05).
