Delayed graft function (DGF) occurs after many pancreas transplants (PTx), but is poorly characterized. We studied its incidence, course, and impact in a series of 531 pancreas transplants. Between January 1997 and September 2002, we performed 531 technically successful primary PTx. Of these 531 recipients, 176 (33%) had DGF, defined by their need for exogenous insulin at the time of hospital discharge. The incidence of DGF was roughly equivalent in the three transplant categories: SPK (36%), PAK (32%), and PTA (31%) (p = NS). By 3 months posttransplant, only 19 (3.5%) of all recipients remained on insulin. Only three recipients (0.56%) did not achieve insulin independence. The mean donor age of recipients with DGF was 35.1 years vs. 28.8 years without DGF (p = 0.003). By multivariate analysis, the most significant risk factor for DGF was donor age > 45 years (RR = 4.3, p = 0.0001). For SPK recipients with DGF, graft survival was 87% at 1 year and 82% at 3 years posttransplant; without DGF, 94% at 1 year and 87% at 3 years (p = 0.07). For PAK and PTA recipients, no difference was noted. Acute rejection rates were somewhat higher in recipients with DGF, but this did not reach statistical significance.
