title: Impact of cyclosporine on renal transplant practice at the University of Texas Medical School at Houston.
abstract: CsA has improved the outcome of renal allotransplantation with CAD and LRD kidneys. CsA mitigates risk factors heretofore presenting substantial obstacles to CAD transplantation: HLA matching, pretransplant splenectomy, extensive numbers of conditioning blood transfusions, and old age. In LRD transplantation, CsA obviates the need for donor-specific transfusions in the haploidentical situation, and for prednisone in the HLA-identical setting. The incidence of drug-induced nephrotoxicity beyond six months is 30% with the degree of dysfunction proportionate to the degree of histo-incompatibility, suggesting that subclinical allograft rejection due to overzealous dose reduction may compromise allograft function. At present, total conversion from CsA to Aza appears ill-advised; even patients who never suffered allograft rejection under CsA therapy frequently lose their allograft when the inferior level of Aza suppression is substituted. Drug-induced hypertension, a modestly significant factor, diminishes further by two years posttransplant. The benefit of CsA therapy is a reduced incidence of 19% initial and 10% recurrent rejection episodes. Of great importance is the observation that 17% of rejection episodes followed patient noncompliance. Further, the incidence of bacterial infections was greatly reduced, and viral infections modestly lessened. Only the occurrence of pneumocystis carinii was increased, but 92% of patients survived in spite of serious pulmonary infection. Development of a consistent CsA regimen has reduced the median initial hospitalization to 12.5 days for LRD and 14 days for CAD, a level well within the range stipulated for the Disease-Related Guidelines of the Medicare Program. Furthermore, readmission is less frequent; one-third of patients never reenter the hospital.(ABSTRACT TRUNCATED AT 250 WORDS)
