Advantages of low dose steroid from the day after renal transplantation.

We have used a low dose of steroid (20 mg of prednisolone), commencing the day after transplantation, for 151 consecutive renal transplants in 141 patients. Five patients received grafts from living related donors, 146 received cadaver grafts. All patients received azathioprine for routine immunosuppression and the first 47 received a single dose of actinomycin C i.v. for treatment of rejection. No other immunosuppressive drugs were used. This treatment provided satisfactory immunosuppression as 109 of 151 grafts continue to function for periods of 3 months to 10 years and, of 42 grafts lost, only 17 failed from rejection. The cumulative survival of first cadaver grafts at 1 and 2 years in recipients of all ages (7 to 55 years) was 77.9 and 76.0%, respectively; in recipients 15 to 34 years old, 90.9 and 86.1%, respectively. Twenty-three patients died, no patient died from infection during the admission for transplantation, and infection played a part in the deaths of only four patients. The incidence of other complications was low; seven patients developed gastrointestinal complications, one died, four patients developed diabetes, all survived; only one patient developed avascular necrosis of bone.

TEN-YEAR RESULTS OF RENAL TRANSPLANTATION WITH AZATHIOPRINE AND PREDNISOLONE AS ONLY IMMUNOSUPPRESSION

93 patients received 102 renal transplants between 1968 and 1977. 99 grafts were from cadavers and 3 were from live donors; 93 were first grafts, 7 were second, and 2 were third. At 10 years total actual patient survival was 66.6%. 50 (55.5%) of 90 first cadaver grafts, and 52.2% of all cadaver grafts, survived at 10 years. Cardiovascular disease was the commonest cause of death, being responsible for 18 of 31 deaths (58%).

Live donor renal transplantation — the experience of the belfast renal unit

SummaryLive donor renal transplants are often preferred to cadaver grafts because of better graft survival. In a retrospective study of 41 live donor transplants performed in the Belfast Renal Unit from 1971 until November 1988, actual graft survival at 2 and 5 years was 84% and 69% respectively. Corresponding patient survival rates were 87% and 81%. These results are no better than those of cadaver grafts. A subdivision of patients considered to be relatively poor risk for transplantation showed less favourable results than those who were good risk. 15% of the donors suffered post-operative complications, which occurred more often in older donors.Live donor transplantation is not necessarily preferable to cadaver organ graft, and is not recommended for poor risk recipients or donors aged over 50 years.
