Outcome of renal transplantation in different primary diseases.

1. Graft survival rates increased about 3-5 percentage points for patients with all primary diseases in 1989-1990. 2. Patients with different diseases had 1-year graft survival rates that varied from 73% for noninsulin-dependent diabetes (NIDDM) to 83% for IgA nephropathy (IgAN). Five-year graft survival varied from 40% for NIDDM to 66% for IgAN. 3. Our findings in Clinical Transplants 1990 that IgAN patients have a high graft survival was confirmed and 1-year graft survival improved by 5% in the last 2 years. 4. There was a 20 percentage point increase in full-time work status of patients after transplantation; 68% of patients with polycystic kidney disease (PKD) and chronic glomerulonephritis (CGN) had full-time work status after 3 years whereas patients with diabetes mellitus (DM) and atheronephrosclerosis (NS) had about 50%. 5. Good early graft function (urine output during the first 24 hours posttransplant, no dialysis within the first-week posttransplant, and no rejection episodes before discharge), predicted good 1-year graft survival for patients with different diseases but patients with NS and DM had a poorer graft survival beyond the first year posttransplant. Patients who had poor early function had 20% lower graft survival than those who had good function. However, in patients with IgAN, no urine at day 1 still resulted in graft survival comparable to those that produced urine. 6. More patients with DM were transplanted within 1 year after going into ESRD than those with other diseases. Conversely, 46% of those with NS did not get transplanted until more than 2 years after developing ESRD. 7. Only 77% of NS patients had functioning grafts at discharge compared to DM (84%), PKD (81%), IgAN (81%), and CGN (80%). 8. Black patients had a statistically significant higher incidence of anuria on the first day compared with Whites. They also had a higher incidence of dialysis and rejection during the first hospitalization. This was true for CGN, DM, PKD, and NS patients. Following excellent early function, Black CGN and DM patients had a higher incidence of rejection than White CGN and DM patients.
