The impact of functioning pancreas-kidney transplantation and pancreas alone transplantation on the lipid metabolism of statin-naïve diabetic patients

Abstract

To compare the lipid profile (total cholesterol - TC, triglycerides - TG, high density lipoprotein cholesterol - HDL-c, low density lipoprotein cholesterol - LDL-c and non-HDL cholesterol - NHDL-c) of patients with functioning pancreas-kidney transplantation (PKT) or pancreas transplantation alone (PTA) after one (T1) and two yr (T2) following their pre-transplantation data (T0). Fifty-three type 1 diabetic patients underwent pancreas transplantation (42 PKT and 11 PTA) remaining euglycemic after transplantation were evaluated before and one and two yr after the procedures. They were using predominantly tacrolimus-mycophenolate mofetil-based immunosuppression and low glucocorticoid dose with systemic venous drainage of the pancreatic graft. None of them used hypolipidemic agents for economical reasons. Lipids were reported as means +/- standard error of the mean. Data obtained in T0 were compared with T1 and T2 using ANOVA followed by Student's t-test. TC, LDL-c, NHDL-c and TG were lower in T1 and T2 when compared with T0 (p < 0.05) in PKT, while no change was observed for HDL-c (p > 0.05). PTA group showed no significant changes in lipids. In spite of the known side effects of tacrolimus-based immunosuppression to lipids, our study with a statin-naïve sample showed improvements (PKT) or stabilization (PTA) in the serum lipid profile after pancreas transplantation.
