Objectives: We used homeostasis model assessment to investigate insulin sensitivity and secretion after a simultaneous pancreas-kidney transplant or kidney transplant alone. In that model, fasting plasma glucose and C-peptide levels are used to evaluate insulin sensitivity and beta-cell function.Materials and Methods: Factors (eg, age, sex, race, delayed kidney allograft function) were correlated with homeostasis model assessment of beta-cell function and homeostasis model assessment of insulin sensitivity values after simultaneous pancreas-kidney transplant (n=89) or kidney transplant alone (n=68), and the results were compared with those in healthy subjects (n=49).Results: Homeostasis model assessment of beta-cell function values were similar in patients who underwent kidney transplant alone or a simultaneous pancreas-kidney transplant, and were higher than homeostasis model assessment of beta-cell function values in healthy subjects. The homeostasis model assessment of insulin sensitivity showed intermediate values for patients who underwent a simultaneous pancreas-kidney transplant and correlated with prednisone dosages (in those who underwent kidney transplant alone) and tacrolimus levels (in patients who underwent a simultaneous pancreas-kidney transplant). Homeostasis model assessment of beta-cell function values correlated with prednisone dosages in both groups and with tacrolimus levels in only those who underwent a simultaneous pancreas-kidney transplant. The body mass index of subjects who underwent kidney transplant alone correlated with both homeostasis model assessment of beta-cell function results and homeostasis model assessment of insulin sensitivity results. A family history of diabetes in subjects who underwent a simultaneous pancreas-kidney transplant correlated with homeostasis model assessment of beta-cell function results and homeostasis model assessment of insulin sensitivity results.Conclusions: Immunosuppressive regimen and body mass index were linked with reduced insulin sensitivity after kidney transplant. A family history of diabetes was linked with higher values of insulin secretion and lower insulin sensitivity in patients who underwent a simultaneous pancreas-kidney transplant.
