The impact of delayed graft function of the kidney on the pancreas allograft in simultaneous kidney-pancreas transplantation.

摘要

It is unclear whether delayed graft function (DGF) of the kidney has any influence on pancreas graft function following simultaneous kidney-pancreas transplantation (SKPT). A subgroup analysis was conducted using data from a multicenter study to determine the impact of DGF of the kidney on pancreas graft function following SKPT. METHODS: Of the 297 SKPT patients, 24 (8%) had DGF of the kidney, defined as the need for dialysis during the first week posttransplant. Clinical parameters including patient and graft survival, incidence of acute rejection, and pancreas and renal function were compared between patients with and without DGF at 1 week, and at 1, 3, 6, and 12 months posttransplant. RESULTS: Demographic and transplant characteristics were similar between the two groups except for longer kidney and pancreas cold ischemia times, more males, and more primary cytomegalovirus (CMV) exposure in the DGF group (P <.05). No differences were seen in patient and graft survival rates, but the incidence of acute renal rejection was higher in patients with DGF (42%) than in those without DGF (15%, P =.001). More patients with DGF (25%) received oral hypoglycemic agents at 1-year posttransplant than in those without DGF (5%, P <.01). At 1 year, the mean serum creatinine was 1.8 mg/dL and 1.4 mg/dL in patients with and without DGF, respectively (P <.01). CONCLUSIONS: Patients with DGF of the kidney had a higher incidence of acute renal rejection and received oral hypoglycemic agents more often during the first year posttransplant compared to those who did not have DGF following SKPT.
