title: Long-term survival of kidney grafts.
abstract: 1. In the long-term period, the half-life effectively measured loss rate. For HLA-identical sib donors the half-life was 25 years; for parental donors, 13 years; and for cadaver donors, 8 years (now possibly 11 years). 2. HLA-A,B,DR matching exerted the greatest effect on half-life, for a half-life of 17 years was achieved for cadaver donors. This rate was not quite as high as that for A,B,DR matched siblings but was higher than the one haplotype mismatched parental donor transplants. 3. Caucasian recipients had a half-life of 8 years compared to 5 years for black recipients. 4. Excellent centers had a 10-year half-life compared to 5 years for fair centers. 5. Cold ischemia time over 24 hours, recipient age over 55, and donor age of 50-60 had a small effect on the half-life in the order of 1 to 3 years. 6. Among the short-term factors that affect the 1-year graft survival, there was a 12% difference between excellent and fair centers. An 11% difference between A,B,DR matched transplants and 6 A,B,DR mismatched grafts was noted. First-cadaver donor grafts had a 10% higher graft survival at 1-year than second grafts. Other factors together with the difference in 1-year graft survival between the extremes were as follows: sensitization 9%, race 8%, transfusion 6%, donor age 6%, diabetic 3%, recipient age 3% and cold ischemia 1%. Thus more factors affect short-term survival than long-term survival.
