Patient presensitization represents a considerable problem in candidacy for renal transplantation. While it is well known that hyperimmunized patients--panel reactive antibody (PRA) higher than 60%--create difficulties in donor matching and have a worse outcome than non-hyperimmunized patients, less information is available on patients with an intermediate degree of sensitization (30-60%). In order to evaluate how graft outcome relates to such degrees of sensitization, 241 consecutive transplanted patients were divided into two groups on the basis of their previous year's PRA peak: group A, PRA 0-29%; group B, PRA 30-60%. Group A showed a significantly better survival both in the first year (90% vs 79%, P < 0.05) and in the third year (82% vs 64%, P < 0.01). However, detailed analysis of group B demonstrated that some parameters may significantly influence graft outcome: (1) better compatibility on locus DR; (2) a primary kidney transplant; (3) a dialysis duration of less than 6 months; and (4) the prophylactic use of antilymphocyte globulin (ALG).

Abstract
Patient presensitization represents a considerable problem in candidacy for renal transplantation. While it is well known that hyperimmunized patients--panel reactive antibody (PRA) higher than 60%--create difficulties in donor matching and have a worse outcome than non-hyperimmunized patients, less information is available on patients with an intermediate degree of sensitization (30-60%). In order to evaluate how graft outcome relates to such degrees of sensitization, 241 consecutive transplanted patients were divided into two groups on the basis of their previous year's PRA peak: group A, PRA 0-29%; group B, PRA 30-60%. Group A showed a significantly better survival both in the first year (90% vs 79%, P < 0.05) and in the third year (82% vs 64%, P < 0.01). However, detailed analysis of group B demonstrated that some parameters may significantly influence graft outcome: (1) better compatibility on locus DR; (2) a primary kidney transplant; (3) a dialysis duration of less than 6 months; and (4) the prophylactic use of antilymphocyte globulin (ALG).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
