Compared with early aABMR, late aABMR had inferior graft survival and was characterized by young age, frequent nonadherence, or suboptimal immunosuppression and de novo donor-specific antibodies.

Aims/hypothesis Mortality due to cardiovascular disease (CVD), particularly coronary artery disease (CAD), is high in type 1 diabetic patients with end-stage renal disease (ESRD). We aimed to determine whether normoglycaemia, as achieved by successful simultaneous pancreas and kidney (SPK) transplantation, could improve long-term outcomes compared with living donor kidney-alone (LDK) transplantation. Methods We studied 486 type 1 diabetic patients with ESRD who underwent a first SPK (n = 256) or LDK (n = 230) transplant between 1983 and 2012 and were followed to the end of 2014. Data were retrieved from the Norwegian Renal Registry and hospital records. Kaplan-Meier plots and multivariate Cox regression, with correction for recipient, donor and transplant factors, were used to examine potential associations between transplant type and all-cause and CVD-and CADrelated mortality. Results Median follow-up time was 7.9 years (interquartile range 4.3, 12.9). The adjusted HR for CVD-related deaths in SPK recipients compared with LDK recipients was 0.63 (95% CI 0.40, 0.99; p = 0.047), while the HRs for all-cause and CAD-related mortality were 0.81 (95% CI 0.57, 1.16; p = 0.25) and 0.63 (95% CI 0.36, 1.12; p = 0.12), respectively. Compared with the LDK group, SPK recipients were younger and received grafts from younger donors. Cardiovascular mortality was higher in patients transplanted between 1983 and 1999 compared with those who received their grafts in subsequent years. Conclusions/interpretation In patients with type 1 diabetes and ESRD, SPK transplantation was associated with reduced long-term cardiovascular mortality compared with LDK transplantation.

Aims/hypothesis We aimed to determine whether simultaneous pancreas and kidney (SPK) transplantation would improve patient and kidney graft survival in diabetic endstage renal disease (ESRD) compared with kidney transplantation alone (KTA). Methods Follow-up data were retrieved for all 630 patients with diabetic ESRD who had received SPK or KTA at our centre from 1983 to the end of 2010. Recipients younger than 55 years of age received either an SPK (n=222) or, if available, a single live donor kidney (LDK; n=171). Older recipients and recipients with greater comorbidity received a single deceased donor kidney (DDK; n=237). Survival was analysed by the Kaplan-Meier method and in multivariate Cox regression analysis adjusting for recipient and donor characteristics.Results Patient survival was superior in SPK compared with both LDK and DDK recipients in univariate analysis. Followup time (mean±SD) after transplantation was 7.1±5.7 years. Median actuarial patient survival was 14.0 years for SPK, 11.5 years for LDK and 6.7 years for DDK recipients. In multivariate analyses including recipient age, sex, treatment modality, time on dialysis and era, SPK transplantation was protective for all-cause mortality compared with both LDK (p=0.02) and DDK (p=0.029) transplantation. After the year 2000, overall patient survival improved compared with previous years (HR 0.40, 95% CI 0.30, 0.55; p<0.001). Pancreas graft survival also improved after 2000, with a 5 year graft survival rate of 78% vs 61% in previous years (1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999). Conclusions/interpretation Recipients of SPK transplants have superior patient survival compared with both LDK and DDK recipients, with improved results seen over the last decade.

Until recently, pancreas transplantation has mostly been performed with exocrine drainage via duodenojejunostomy (DJ). Since 2012, DJ was substituted with duodenoduodenostomy (DD) in our hospital, allowing endoscopic access for biopsies. This study assessed safety profiles with DD versus DJ procedures and clinical outcomes with the DD technique in pancreas transplantation. DD patients (n = 117; 62 simultaneous pancreas-kidney [SPK ] and 55 pancreas transplantation alone [PTA ] with median follow-up 2.2 years) were compared with DJ patients (n = 179; 167 SPK and 12 PTA ) transplanted in the period 1998-2012 (pre-DD era). Postoperative bleeding and pancreas graft vein thrombosis requiring relaparotomy occurred in 17% and 9% of DD patients versus 10% (p = 0.077) and 6% (p = 0.21) in DJ patients, respectively. Pancreas graft rejection rates were still higher in PTA patients versus SPK patients (p = 0.003). Hazard ratio (HR) for graft loss was 2.25 (95% CI 1.00, 5.05; p = 0.049) in PTA versus SPK recipients. In conclusion, compared with the DJ procedure, the DD procedure did not reduce postoperative surgical complications requiring relaparatomy or improve clinical outcomes after pancreas transplantation despite serial pancreatic biopsies for rejection surveillance. It remains to be seen whether better rejection monitoring in DD patients translates into improved long-term pancreas graft survival.
