Compared with BD, (a) perioperative morbidity is not increased by ED, (b) ED is associated with fewer complications and hospitalizations, and (c) ED is not associated with increased long-term pancreas graft failure. These data suggest that ED is superior to BD and should be considered as the preferred technique for simultaneous pancreas-kidney transplants.

Patients with insulin-dependent diabetes who receive pancreas/kidney transplants lose their need for insulin injections, but they become hyperinsulinemic and insulin resistant, and sometimes develop noninsulin-dependent diabetes mellitus. The reason for the insulin resistance is not well understood. Specifically, it is not known whether they become resistant to the action of insulin on lipid metabolism. Euglycemic-hyperinsulinemic clamps were performed in six pancreas/kidney (P/K) recipients, six kidney (K) recipients (to control for immunosuppressive therapy), and eight healthy controls. Measured were leg blood flow (by plethysmography), rates of lipolysis (with [2H5] glycerol), fatty acid oxidation (by indirect calorimetry), fatty acid reesterification (with [2H5]glycerol and [1-13C]palmitate), monocyte membrane insulin binding (with [125I]Tyr-A14 insulin), and insulin receptor mass (by RIA). Fasting plasma insulin concentrations were 2 times higher in P/K and K recipients (108 pmol/L) than in controls (54 pmol/L). Insulin receptor mass in solubilized monocyte membranes from P/K and K recipients was reduced by 61% and 63%, respectively, whereas insulin binding was reduced by 73% and 70%, respectively. P/K and K recipients were resistant to the inhibitory action of insulin on lipolysis (P/K vs. controls, P < 0.01; K vs. controls, P < 0.02) and on fatty acid reesterification (P/K vs. controls, P < 0.02; K vs. controls, P < 0.03). P/K recipients appeared to be more resistant than K recipients, but the differences between the two groups were not statistically significant. We conclude that P/K recipients were hyperinsulinemic, had down-regulated the number of their monocyte insulin receptors, and were resistant to the antilipolytic action of insulin.
