title: Lipoprotein profile after combined kidney-pancreas transplantation in insulin dependent diabetes mellitus.
abstract: In order to evaluate the effect of a combined kidney-pancreas (KP) transplantation in insulin-dependent diabetes mellitus (IDDM) patients on the lipid and lipoprotein profile, 15 KP patients were compared with 11 kidney (K)--transplanted IDDM patients, 19 IDDM patients on hemodialysis (HD), and 15 nondiabetic control subjects. Cholesterol, triglycerides, apo AI, and apo B were measured in total plasma and in VLDL, LDL, and HDL of all participants. VLDL cholesterol, VLDL-triglycerides, and VLDL-apo B were significantly lower in KP patients, but not in K patients, than in HD patients. In addition, patients in the K, but not in the KP, group showed high levels of apo B in LDL and an increased triglyceride/apo B ratio in VLDL, compared with patients in the HD group. The percentage of apo AI associated with HDL was significantly higher in both transplanted groups than in the HD group. However, compared with a nondiabetic control population, an increase in VLDL particles and in triglyceride content in LDL and HDL still persisted following combined KP transplantation. Insulin resistance (probably due to steroid therapy) associated with high peripheral and potentially low hepatic insulin levels (due to the systemic drainage of the transplanted pancreas) could be the main causes of the remaining lipoprotein abnormalities.
