Long-term results of tacrolimus therapy for renal transplantation in patients with diabetic nephropathy in Japan.
In Japan, the number of kidney transplants for the patients with diabetic nephropathy is limited because of an extreme organ shortage and poor patient and graft survival rates. We analyzed the 5-year outcomes in kidney transplant recipients treated with tacrolimus with (group 1; n = 53) and without a diagnosis of diabetic nephropathy (group 2; n = 1432). We also investigated outcomes in patients who received simultaneous pancreas and kidney transplants since 2000 (group 3; n = 15). Patients in group 1 were older than those in group 2, with a shorter duration of pretransplant dialysis (P = .0001). Five-year patient survival rates in groups 1 and 2 were 89.7% and 97.9%, respectively (P = .13), and 5-year graft survival rates were 89.6% and 94.8%, respectively (P = .44). The incidence of acute rejection within 3 months of transplantation was 28.3% in group 1 and 29.2% in group 2 (P = .98). Tacrolimus-based induction therapy was used in 13 of the 15 group 3 cases. Both kidney and pancreas grafts are surviving to date in all but one of the group 3 patients; one patient had the pancreas removed due to venous thrombosis at 7 days. It was concluded that tacrolimus-based therapy resulted in excellent 5-year outcomes in patients who had kidney transplantation because of diabetic nephropathy, despite the higher risks associated with this condition. Tacrolimus was also beneficial in association with simultaneous pancreas and kidney transplantation. These data encourage us to perform kidney transplantation in patients with diabetic nephropathy.
