The consequences for live kidney donors with preexisting glucose intolerance without diabetic complication: analysis at a single Japanese center.
BACKGROUND
Because of lack of deceased donors in Japan, there has been a need to expand the eligibility criteria for live kidney donation. To assess the indications for live kidney donation in glucose intolerance (GI), we analyzed perioperative complications associated with donor nephrectomies performed at our institution and followed up the long-term consequences.


METHODS
The 444 live kidney donors were divided into two groups based on the results of the 75-g oral glucose tolerance test: a GI group (n=71) who showed a diabetic (n=27) or impaired glucose tolerance (n=44) pattern, and a non-GI group (n=373) who showed a normal oral glucose tolerance test pattern. Perioperative complications, longterm survival rate, and frequencies of hypertension, diabetes, hyperlipidemia, and renal dysfunction in long term were compared in each group.


RESULTS
The incidence of perioperative complications was not higher in the GI group than in the non-GI group (4.3% vs. 5.4%, respectively; NS). Survival rates in the GI group at 5, 10, and 20 years were 98.3%, 95.1%, and 89.2%, respectively, whereas those in the non-GI group were 98.0%, 96.1%, and 91.5%, thus showing equivalent mortality. None of the patients in the diabetes mellitus group had developed severe diabetic complications or end-stage renal disease at a mean follow-up point of 88+/-71 (range, 14-225) months.


CONCLUSIONS
Our results suggest that individuals who have GI without diabetic complication may be able to donate their kidney safely with little surgical complication and little major morbidity if strict evaluation is performed before transplant.
