This is an immunocytochemical study of the relationship between depletion of natural anticoagulant and fibrinolytic pathways and allograft survival following renal transplantation. Patients (n = 44) were classified in three groups according to the length of time between transplantation and allograft failure: group 1 (n = 14) failed within a month of transplantation; group 2 (n = 14) failed between one month and one year after transplantation; and group 3 (n = 16) failed after one year of transplantation. Control biopsies were from donor kidneys (n = 16) prior to transplantation. There were no statistically significant differences in recipient age, gender, donor kidney type (living-related versus cadaver), histocompatibility, and plasma cholesterol, triglycerides, or creatinine concentrations between groups. However, group 1 allografts had a greater depletion of the vascular heparan sulfate proteoglycan-antithrombin III natural anticoagulant pathway than allografts in group 2 or 3 (P < or = 0.05), and this depletion was associated with significantly greater fibrin deposition in group 1 than in either group 2 or 3 (P < or = 0.05). All three groups demonstrated severe depletion of tissue plasminogen activator from arteriolar smooth muscle cells and depressed fibrinolysis as evidenced by increased fibrin/plasmin ratios. However, no significant differences were found for either endothelial thrombomodulin or T cell, neutrophil, or macrophage infiltration between the groups. These data indicate that differences in graft outcome may be determined more by compromised vascular function than by the presence of cellular infiltrates.
