Clinical outcomes of simultaneous pancreas-kidney transplantation in elderly type II diabetic recipients

The effect of age on outcomes after simultaneous pancreas-kidney transplantation (SPK) among type II diabetes (T2DM) recipients remains inconclusive. This study aimed to analyze the relationship between the age at time of transplantation and mortality, graft loss and metabolic profiles of T2DM SPK recipients. A retrospective cohort consisting of T2MD SPK recipients in a single transplant center was established. The baseline clinical characteristics and outcomes were collected and analyzed based on the age groups divided by 55-year-old. Time-to-event data analysis was performed using Kaplan-Meier method, and competing risk method was adopted to calculate the cumulative incidence of graft loss. A mixed regression model was applied to compare metabolic outcomes including glycated hemoglobin (HbA1c), fasting blood glucose, triglyceride, cholesterol, low-density lipoprotein, and higher estimated glomerular filtration rate (eGFR). 103 T2DM SPK recipients were included, of which 35 were > = 55 years old and 68 were < 55 years old. Baseline characteristics were comparable between age groups. The results indicated that comparable 5-year survival outcomes between groups with functioning grafts perioperatively. Additionally, no relationship of age with graft loss, complications and metabolic outcomes was detected.
