- Abstract
Tissue and plasma concentrations of pentose-derived glycation end-products (‘pentosidine’) are elevated in diabetic patients with normal renal function and in both diabetic and nondiabetic patients with end-stage renal disease. To determine the effects of correcting hyperglycemia and/or renal failure on the accumulation of pentosidine, we used reverse phase and ion exchange high performance liquid chromatography to measure this advanced glycation end-product in plasma proteins of diabetic and nondiabetic transplant recipients at various time intervals after kidney-pancreas or kidney transplantation. Changes in plasma pentosidine levels after transplantation were compared to changes in simultaneously obtained glycohemoglobin levels. Both kidney and kidney-pancreas transplantation were accompanied by a dramatic, but incomplete, reduction of plasma pentosidine concentrations within three months of transplantation. Kidney-pancreas transplantation resulted in normal glycohemoglobin levels within three months but offered no advantage over kidney transplantation alone in the partial correction of plasma pentosidine levels. There was no correlation between posttransplant plasma pentosidine and glycohemoglobin levels in either diabetic or nondiabetic transplant recipients. We conclude that renal failure is the major factor accounting for the accumulation of pentosidine in bath diabetic and nondiabetic patients with end-stage renal disease. Restoration of euglycemia after kidney-pancreas transplantation provides no additional benefit in reducing plasma pentosidine levels to that achieved by correction of renal failure after kidney transplantation alone.
