A histological analysis of 2564 endomyocardial biopsies was conducted in 349 cardiac transplant patients to determine potential risk factors for acute cellular rejection during the first three months following transplantation. This analysis dealt with the frequency, time of onset, and duration of cellular rejection. Patients on perioperative RATG experienced significantly less rejection than patients on OKT3 or without antilymphocyte antibody immunoprophylaxis. A trend was noted toward increased rejection in recipients diagnosed originally with chronic myocarditis compared with patients in other disease categories including ischemic heart disease and dilated cardiomyopathy. No significant differences were seen in histological rejection between male and female recipients. On the other hand, patients over 55 years of age were found at lower risk of histological rejection. The results of this analysis have demonstrated quite clearly, but not unexpectedly, that a greater degree of HLA mismatching correlates with increased cellular rejection. This effect was noted not only for the HLA-A,B and DR antigens, but also HLA-DQ and HLA-DRw52/53 antigens. In multivariate analysis, the highest level of statistical significance was obtained for the combined HLA-A,B,DR and DQ group. Sensitized patients with panel-reactive lymphocytotoxic antibodies of greater than 10% experienced more histological rejection than nonsensitized patients. On the other hand, a positive lymphocytotoxic crossmatch did not appear to influence cellular rejection of cardiac allografts. Also, no differences were seen in histological rejection between ABO-identical and compatible heart transplants. These findings further support the concept that donor HLA compatibility and pretransplant sensitization represent significant risk factors for cellular rejection in cardiac transplantation.
