Prediction model to discard a priori liver allografts.

BACKGROUND: The use of expanded criteria for donors to expand the donor pool has increased the number of discarded liver grafts in situ. The aim of our study was to elaborate a prediction model to reduce the percentage of liver grafts discarded before the procuring team is sent out. METHODS: We analyzed the donor factors of 244 evaluated candidates for liver donation. We performed a multiple logistic regression to evaluate the probability of liver grafts discarded (PD). RESULTS: The PD was determined by use of 3 variables: age, pathological ultrasonography, and body mass index >30. The area under curve was 82.7%, and, for a PD of 70%, the false-positive probability was 1.2%. CONCLUSIONS: We have created a useful clinical prediction model that could avoid up to 20% of discarded liver grafts.

One hundred one simultaneous pancreas-kidney transplantations: long-term outcomes at a single center.

INTRODUCTION: Among patients with type 1 diabetes mellitus and end-stage renal disease, simultaneous pancreas-kidney (SPK) transplantation is associated with increased survival compared with solitary kidney transplants or dialysis. METHODS: A retrospective, descriptive study was performed on 101 consecutive SPK transplantation performed in our center over the last 20 years. We excluded six pancreas alone, eight pancreas after kidney, and four retransplantations. We analyzed demographic characteristics and patient and graft survivals. We also compared patient and pancreatic graft survivals between three periods: 1989 to 1999, 2000 to 2003, and 2004 to 2007. In the first period, bladder drainage was performed in all patients. In the second and third periods, it was replaced by enteric drainage. RESULTS: Overall patient survival was 83.2%. Kidney graft loss occurred in 12 (11.8%) patients and pancreas graft loss in 21 (20.7%) patients. Overall pancreatic graft survival was 79.2% with a 1-year value of 87.1%. By periods, pancreatic graft survival was 75% during the bladder drainage era; 76.9% in the second period; and 85.7% in the third period (P = .88). CONCLUSION: SPK transplantations in diabetic patients with end-stage renal disease were associated with improving pancreas graft survival throughout the study period.
