title: Recurrent and de novo renal diseases after renal transplantation: a report from the renal allograft disease registry.
abstract: Recurrent or de novo glomerular disease is an important cause of graft dysfunction and eventual loss. Cyclosporine A (CyA) has improved short-term renal allograft outcome but has not altered long-term graft survival. The purpose of the current study is to determine the prevalence of such disease and its impact on graft function in the CyA era. From 1984 to 1994, 1,557 renal allografts were performed at the Medical College of Wisconsin and the University of Cincinnati. Patients were followed up for an average of 7.2 years (minimum, 1 year). Recurrent disease was diagnosed by renal biopsy in 98 (6.3%) patients after an average of 36 months. Demographic characteristics of patients with and without recurrent disease were similar. Glomerulonephritis was the most common finding, occurring in 73 patients, and included focal segmental glomerulosclerosis (FSGS), 25; IgA nephropathy (IgAN), 11; membranous (MN), 11; proliferative, 11; membranoproliferative glomerulonephritis (MPGN), 10; glomerular basement membrane (anti-GBM), 3; and systemic lupus erythematosus (SLE), two. Diabetic nephropathy was present in 22, hemolytic uremic syndrome (HUS) in two, and oxalosis in one. Graft loss occurred in 60 of 98 (61%) recipients. Half-life of the allograft was diminished in patients with recurrent disease, 2,038 +/- 225 versus 3,135 +/- 385 days, P = 0.002. The actuarial allograft survival at 1, 3, 5, and 8 years posttransplantation with recurrence was 88%, 74%, 57%, and 34%, respectively; and the corresponding graft survival for patients without recurrent disease was 80%, 70%, 64%, and 53%, respectively (P = 0.003). The risk of recurrent disease increased with length of graft survival from 2.8% at 2 years to 9.8% and 18.5% at 5 and 8 years, respectively. We conclude that recurrent disease is a significant problem after renal transplantation and is associated with decreased graft survival.
