title: Blood and graft eosinophilia as a rejection index in kidney transplant.
abstract: The relevance of eosinophilia in the physiopathology of transplant rejection has yet to be established. The appearance of eosinophilia has been occasionally associated with an adverse prognosis on graft rejection episodes. The aim of the present study was to evaluate the role and prognostic implications of blood and graft eosinophilia in kidney transplant rejection. We have examined the intrarenal infiltrate in 173 fine-needle aspiration biopsies from 36 consecutively transplant patients, and blood samples obtained simultaneously with fine-needle aspirations. Two different immunosuppressive regimens were administered: triple therapy (azathioprine + prednisone + antilymphocytic globulin) in patients with posttransplant acute tubular necrosis and cyclosporine A monotherapy in the rest of the patients. Comparing the two immunosuppressive groups, more elevated eosinophil values were observed in the monotherapy group during stable graft and also at the rejection episode. In the monotherapy group, a significant increase in the eosinophil values, in peripheral blood samples and in the intragraft infiltrates were noted at the rejection episode with respect to the stable situation. Following pulsed-steroid treatment an immediate disappearance of the eosinophils was evident. In contrast, no differences could be demonstrated between these two clinical situations in the TT group. Higher rates of eosinophils in the intrarenal infiltrate with respect to peripheral blood samples were observed during rejection episodes, suggesting some role of the eosinophils in the physiopathology of graft rejection.(ABSTRACT TRUNCATED AT 250 WORDS)
