Abstract
Background. There is a high incidence of silent coronary artery disease (CAD) in patients with diabetes. We wanted to investigate risk factors for mortality, and especially CAD, in a well-defined cohort of diabetic nephropathy transplant candidates accepted for transplantation. Methods. From 1999 through 2004, 155 patients underwent work up for living or deceased kidney (KA) or simultaneous pancreas-kidney (SPK) transplantation. The work up included coronary angiography for all patients and 136 were accepted. Mean (SD) age was 50 (12) years, 62% had type 1 diabetes, 73% were males, and 34% were on dialysis. Mean follow-up from time of acceptance for transplantation was 3.6 (1.9) years. Results. Survival of KA transplanted patients was 97% at 1 year, 89% at 3 years, and 76% at 5 years, whereas in SPK patients 100%, 94%, and 90%, respectively (P=0.065). One- and 3- year survival was only 57% and 20% in those remaining wait-listed (PP=0.011) and SPK transplantation (HR=0.10, P=0.001), and age (HR=1.04, P=0.014). In multivariable analysis, KA transplantation (HR=0.28, P=0.006), SPK transplantation (HR=0.09, P=0.001), age (HR=1.06, P=0.002), type 2 diabetes (HR=0.14, P=0.003), and duration of diabetes (HR=0.94, P=0.019) were parameters associated with mortality. Conclusions. The only modifiable risk factor was transplantation with risk reduction up to 90%. CAD was not a risk factor for mortality when medically treated and revascularized according to standard guidelines.Keywords
