Impacto da função retardada do enxerto pancreático no transplante simultâneo pâncreas-rim

Abstract

Simultaneous pancreas-kidney transplantation is an effective treatment for patients with type 1 diabetes mellitus and end-stage chronic kidney disease. Delayed pancreatic graft function is a common and multifactor condition with significant impact in short-term outcome of simultaneous pancreas-kidney transplantations. The aim of this study was to analyze the impact of pancreatic delayed pancreatic graft function on simultaneous pancreas-kidney transplantation. Donor and recipient's demographic data, percentage of panel reactivity, acute rejection incidence, and patient and grafts survivals were retrospectively analyzed in 180 SPKT performed between 2002 and 2007. The incidence of pancreatic delayed pancreatic graft function was 11%. Donors older than 45 years had significant risk of pancreatic delayed pancreatic graft function (OR 2.26; p < 0,05). Patients with pancreatic delayed pancreatic graft function had higher rates of acute renal rejection (47 versus 24%; p < 0.05), altered fasting plasma glucose (25 versus 5%; p < 0.05) and mean glycated hemoglobin (5.8 versus 5.4%; p < 0.05), than patients without pancreatic delayed pancreatic graft function at the end of the first year of follow up. There were no significant differences between patients with and without pancreatic delayed pancreatic graft function regarding patient survival (95 versus 88.7%; p = 0.38), pancreatic graft survival (90 versus 85.6%; p = 0.59) and renal graft survival (90 versus 87.2%; p = 0.70), respectively at the sample period of time. Pancreatic delayed pancreatic graft function had no significant impact in the short-term outcome of simultaneous pancreas-kidney transplantations. Although delayed pancreatic graft function had no impact on 1-year pancreas graft survival, it contributed to early pancreas graft dysfunction, as assessed by enhanced insulin and oral anti-diabetic drugs requirements.
