title: The UNOS Scientific Renal Transplant Registry--1991.
abstract: Based upon data reported to the UNOS Scientific Renal Transplant Registry between October 1987 and November 1991: 1. One-year graft survival rates were 79%, 73% and 62% for recipients of first (20,864), second (3,217), and multiple (673) cadaver donor transplants, respectively. 2. One-year graft survival rates were 94%, 89%, and 90% for first transplant recipients of kidneys from HLA-identical siblings (970), parents (1,487), and 1-haplotype-mismatched siblings (1,206), respectively. 3. Half-lives calculated after the first year were 7 years for cadaver donor transplants, 11 years for parent, 12 years for 1-haplotype sibling and, 27 years for HLA-identical sibling-donor first transplants. 4. The 1-year first transplant survival rate has improved from 78% in 1987-88 to 80% in 1990-91 transplants (p = 0.001). There has been an attendant decline in the percentage of broadly sensitized patients transplanted from 15% in 1987 to 8% in 1990 (p less than 0.01), which may have contributed to rising survival rates. 5. There has been a remarkable improvement in the 1-year graft survival of retransplanted patients from less than 70% in 1987-88 to 78% in 1990 (p less than 0.001). This improvement has been most notable in broadly sensitized patients and those with delayed graft function. 6. Diabetics who received a pancreas and kidney transplant (995) had 81% 1-year graft survival compared to 77% for those who received a kidney transplant only (p less than 0.002). 7. One-year graft survival rates decreased significantly in recipients of kidneys from donors aged under 16 or over 45. Survival was less than 70% when the donor was under 5 or over 60 compared to 81% when the donor was aged 16-45 (p less than 0.001) for recipients of first cadaver transplants. Delayed graft function occurred in 40% of cases when the donor was over 60 and 28% of cases when the donor was under 5. When function was delayed, survival was 50% for these marginal kidneys compared to 68% for younger adult kidneys with delayed function (p less than 0.001). Rejection also had a greater impact on survival of kidneys from donors under 5 or over 60. 8. The 1-year graft survival rate for 2,504 first transplant recipients of cadaver kidneys from young male victims of traffic accidents was 85%. The 1-year graft survival of 2,670 patients given kidneys from older female donors who died of cerebrovascular accidents was 73% (p less than 0.001).(ABSTRACT TRUNCATED AT 400 WORDS)
