Abstract
Background
Tacrolimus (Tac) can cause impaired insulin release and dyslipidemia, and may affect the development of post-transplant diabetes mellitus. However, these effects on insulin sensitivity and lipid profile have not been compared in renal transplant recipients receiving traditional twice-daily tacrolimus (TacBID) or cyclosporine and those receiving once-daily prolonged release formulation of tacrolimus (TacOD).
Methods
We conducted an observational prospective study of 15 stable non-diabetic renal transplant recipients to observe the changes in insulin sensitivity and lipid profiles for 1 year at a tertiary hospital. We evaluated the levels of hemoglobin A1c, total cholesterol, high density lipoprotein, low density lipoprotein, triglycerides, apolipoprotein A1, apolipoprotein B, serum creatinine, fasting plasma glucose, fasting insulin, homeostatic model assessment of β-cell (HOMA-β) and HOMA-insulin resistance index at baseline and at 2 and 4 months. To analyze differences in parameters, we conducted a Wilcoxon rank sum test and general linear model (GLM)-repeated measures analysis of variance (ANOVA) in both groups (cyclosporine to TacOD conversion group/TacBID to TacOD conversion group).
