High versus "low" dose corticosteroids in recipients of cadaveric kidneys: prospective controlled trial

Corticosteroids have the major role in the immunosuppressive treatment of patients who have received renal transplants. Despite their extensive use there is still debate about the appropriate dose that will prevent rejection of the renal allograft with the least morbidity. From March 1979 to November 1981 a randomised controlled trial of high (33 patients) v low oral dose (34 patients) of prednisolone along with azathioprine was conducted in recipients of first cadaveric transplants who had received a blood transfusion within six months of transplantation. The main difference in outcome between the two groups was a high incidence of some infections in the high dose group. Patient mortality, graft survival, transplant function, and number of rejection episodes were indistinguishable in the two groups, but rejection episodes tended to occur later in the high dose group. These findings suggest that the use of lower doses of corticosteroids soon after cadaveric renal transplantation does not jeopardise graft survival and results in lower patient morbidity.
