Dietary restriction (DR), defined as reduced energy intake without malnutrition, confers protection against renal ischemia and reperfusion injury in animal models. This pilot study investigates for the first time the feasibility of pre-operative DR in the clinical setting. Live-kidney donors were randomized between pre-operative DR or ad libitum intake. Seventeen participants were instructed to follow a 30% calorie-restricted diet, followed by one day of water-only fasting prior to surgery. Thirteen participants were allowed to eat ad libitum pre-operatively. Ninety-four percent of the donors adhered to the diet, 31.4% reduction in caloric intake was achieved. Post-operative well-being, appetite and ability to perform daily tasks were not different between both groups. There was no difference in post-transplant graft function of kidneys obtained from DR donors or control donors as determined by serum creatinine levels during the first post-operative month and renograms at post-operative day one. This study shows that mild dietary restriction is feasible in the setting of live-kidney donation. No effect was observed regarding post-operative graft function. Additional studies are warranted to investigate the appropriate regimen of dietary restriction to protecting against ischemia and reperfusion injury, such as increasing the magnitude and/or duration of the reduction in daily caloric intake.
