Popis: Pancreas after kidney (PAK) transplantation is one of the accepted pancreas transplant modalities. We studied the impact of time interval between kidney and pancreas transplantation on the outcomes of PAK transplantation. Using OPTN/SRTR data, we included 1853 PAK transplants performed between 1996 and 2005 with follow-up until November 1, 2008. Kaplan-Meier survival and multivariate Cox regression analyses were performed using the time interval between kidney and pan- creas transplantation either as a categorical (less than one yr, between one and less than three yr, and greater than or equal to three yr) or as a continuous variable (months) to assess kidney graft and patient survival. Patients who received a pancreas transplant three yr or later after kidney transplantation had higher risk of death-censored kidney graft loss (HR 1.56, 95% CI 1.04, 2.32, p = 0.03). Each month beyond three yr between kidney and pancreas transplantation incurred 1% higher risk of subsequent death-censored kidney graft loss (HR 1.01, 95% CI 1.001, 1.02, p = 0.03). In conclusion, time interval between pancreas and kidney transplantation is an independent risk factor of kidney graft loss following pancreas trans- plantation. Shortening the time interval between pancreas and kidney transplantation to less than three yr may reduce the risk of kidney graft loss in qualified PAK transplant candidates.
