Abstract

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 CAD-related 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.
