    Abstract:
    BACKGROUND: Simultaneous pancreas-kidney transplantation (SPKT) is one of the treatments for insulin-dependent chronic renal failure patients. METHODS: One-year patient and kidney allograft survival rates of 150 patients undergoing SPKT were subjected to Cox regression and Kaplan-Meier analyses. Uni- and multivariate methods identified risk factors involved in allograft and patient survival. RESULTS: One-year patient and kidney allograft survival rates were 82% and 80%, respectively. Delayed graft function (DGF) (P = .001; hazard ratio [HR]5.41) and acute kidney rejection episodes (P = .016; HR 3.36) were related to 1 year patient survival as well as intra-abdominal infection (IAI) rates. (IAI). One-year kidney allograft survival was related to DGF (P = .013; odds ratio [OR] 3.39), acute rejection (P = .001; OR 4.74), and IAI (P = .003, OR 6.29). DGF was related to a time on dialysis >27 months (P = .046; OR 2.59), cold kidney ischemia time >14 hours (P = .027; OR 2.94), donor age >25 years (P = .03; OR 2.82), and donor serum sodium concentration >155 mEq/L (P < .0001; OR 1.09). Female kidney to male recipient in 17% of the cases did not increase the risk of DGF. We observed an important correlation between donor serum sodium and creatinine (P < .0001), which suggested undertreatment of diabetes insipidus secondary to brain death. CONCLUSIONS: DGF, acute rejection, and IAI were the main determinants of survival after SPKT. Improving the care of deceased donors may reduce DGF occurrence.
