Abstract

Abstract : Background: Cardiovascular disease is the major cause of death in patients with type 1 diabetes. Of the available risk predictors for this population, the Steno Type 1 Risk Engine (STENO T1) is the only one that includes kidney function as a risk factor, which is a well-described independent risk factor for cardiovascular disease. Methods: We explore how simultaneous pancreas-kidney transplantation (SPKT) modifies the predicted cardiovascular risk by the STENO T1 through a retrospective study including recipients of a first SPKT between 2000 and 2016. Results: Two hundred sixty-eight SPKT recipients with a mean age of 40 y old and a median follow-up of 10 y were included. Before transplantation, the expected incidence of cardiovascular events (CVEs) at 5 and 10 y according to STENO T1 would have been 31% and 50%, respectively, contrasting with an actual incidence of 9.3% and 16% for the same timepoints, respectively ( P < 0.05). These differences were attenuated when STENO T1 was recalculated assuming 12th-mo glomerular filtration rate (at 5 and 10 y predicted CVE incidence was 10.5% and 19.4%, respectively). Early pancreas graft failure (hazard ratio [HR] 3.00, 95% confidence interval [CI], 1.14-7.88; P = 0.02) was an independent risk factor for post-SPKT CVE, alongside kidney graft failure (HR 2.90, 95% CI, 1.53-5.48; P = 0.001), and diabetes duration (HR 1.04, 95% CI, 1.00-1.09, P = 0.04). Conclusions: SPKT decreases in more than two-thirds of the predicted cardiovascular risk by the STENO T1. A functioning pancreas graft further reduces CVE risk, independently of kidney graft function. Abstract : Supplemental Digital Content is available in the text.
