    Abstract:
    Endomyocardial diagnostic biopsies, recipient heart removed at operation, endomyocardial biopsies of allotransplants and postmortem material were studied using immunofluorescence to specify immunopathological process and to detect humoral rejection. Altogether 306 samples from 55 patients were studied. In the early postoperative period (one year) 8 out of 18 patients with heart transplants repeatedly showed immunopathologic picture of acute humoral (vascular) rejection which was characterized by a widespread immunoglobulin G and complement fixation in the capillary walls accompanied by enhanced capillary permeability and fibrin deposition in intestitial tissue. Such patients often had graft dysfunction. 1 to 5 years after transplantation in 24 out of 37 patients discrete focal immunoglobulin and complement fixation was observed as one of chronic rejection component.
