Outcomes of renal transplantation after end-stage renal disease due to diabetic nephropathy: a single-center experience.
BACKGROUND
Diabetic nephropathy is the most common cause of end-stage renal disease (ESRD) worldwide. However, data on renal transplantation outcomes in diabetic nephropathy among Japanese remain inadequate. This retrospective study was conducted to summarize our renal transplantation experience in diabetic ESRD patients.


METHODS
We retrospectively studied 462 patients who underwent kidney transplantation between 1989 and 2011, including 23 with diabetic ESRD (DM group) and 439 with nondiabetic ESRD (NDM group). We compared demographic and clinical variables between these 2 groups.


RESULTS
Mean age was higher in the DM group (48.0 vs 38.2 years; P < .001), and there was no significant difference in gender or donor source. The 1-, 3-, and 5-year graft survival rates in the DM and NDM groups were 100% vs 98.3% (ns), 82.4% vs 94.9% (P < .05), and 66.7% vs 90.3% (P < .01), respectively. The 1-, 3-, and 5-year patient survival rates were 95.0% vs 96.5% (ns), 88.2% vs 95.2% (ns), and 84.6% vs 92.9% (ns), respectively. One patient (4.3%) in the DM group and 6 (1.4%) in the NDM group died from cardiovascular disease during the follow-up period (ns). The incidence of rejection did not differ between the DM and NDM groups. There were no significant differences in the total infection rate or the urinary tract infection rate.


CONCLUSIONS
Renal transplantation in diabetic ESRD patients yields good results in terms of patient survival and complications, suggesting that renal transplantation can be performed in these patients and should become a more established treatment option.
