Long-Term Pancreas Allograft Survival in Simultaneous Pancreas-Kidney Transplantation by Era
نویسندگان
چکیده
Data collected by UNOS from all approved US transplant programs were analyzed. The analysis was based on data for 22,075 diabetic patients who received a pancreas transplant between January 1995 and December 2011. Simultaneous pancreas-kidney (SPK) transplantation was the major therapeutic option for diabetes patients. SPK had better survival than pancreas transplantation alone (PTA) or pancreas-after-kidney (PAK) transplantation. The 5-year pancreas graft survival rate for SPK, PAK, and PTA was 71.3%, 56.6%, and 53.0%, respectively. When long-term SPK pancreas graft survival was examined by transplant era, there was no survival improvement after 1995. The effect of year of transplant was estimated using Cox proportional hazard models. The 5-year pancreas graft survival rate in the eras 1995-1998, 1999-2002 and 2003-2006 were 69.2%, 69.8%, and 72.4%, respectively. For those whose graft survived over one year, the 5-year graft survival rate in those eras was 83.5%, 83.4%, and 85.2%, respectively. The adjusted hazard ratio for overall graft loss by year of transplant for the grafts that survived more than one year in the eras 1999-2002 and 2003-2006 was 1.08 (95% confidence interval [CI], 0.94-1.24) and 0.95 (95% CI, 0.82-1.11), respectively. The survival rate of long-term pancreas grafts remained almost unchanged over time.

Incremental Value of the Pancreas Allograft to the Survival of Simultaneous Pancreas-Kidney Transplant Recipients
OBJECTIVE To quantify the incremental survival benefit of the pancreas allograft in simultaneous pancreas-kidney (SPK) transplant recipients. RESEARCH DESIGN AND METHODS Data from the national transplant database from 2000 to 2007 were analyzed. SPK recipients who had functioning allografts to 1-year post transplant (n = 3,304) were compared with those who had failure of the renal (n = 233) o...
متن کاملSelected Mildly Obese Donors Can Be Used Safely in Simultaneous Pancreas and Kidney Transplantation.
BACKGROUND Donor obesity, defined as donor body mass index (D-BMI) of 30 kg/m or greater, has been associated with increased risk of technical failure and poor pancreas allograft outcomes. Many transplant centers establish a threshold of D-BMI of 30 kg/m to decline donor offers for pancreas transplantation. However, no previous studies differentiate the impact of mild (D-BMI, 30-35 kg/m) versus...

Pancreas allograft acceptance is markedly more selective than other solid organs. The number of pancreata recovered is insufficient to meet the demand for pancreas transplants (PTx), particularly for patients awaiting simultaneous kidney-pancreas (SPK) transplant. Development of a pancreas donor risk index (PDRI) to identify factors associated with an increased risk of allograft failure in the ...
