    Abstract:
    It was hypothesized that peripheral arterial disease (PAD) is less frequent after kidney transplantation than among comparable patients who are on the deceased-donor waiting list. The cumulative incidences and risk factors for PAD were compared among 43,427 adult transplant recipients and 53,309 adults who were placed on the renal transplant waiting list between 1995 and 2003. All patients had Medicare primary insurance coverage, and Medicare claims were used to identify PAD. For patients with diabetes, the 3-yr cumulative incidence of de novo PAD was 24% on the waiting list versus 20% after transplantation. For patients without diabetes, the 3-yr cumulative incidence was 9% on the waiting list versus 5% after transplantation. The adjusted relative risk (RR) for PAD among patients without diabetes was 0.73 (95% confidence interval [CI] 0.66 to 0.80; P < 0.0001) in the transplant population versus the waiting list population, whereas among patients with diabetes, it was 0.88 (95% CI 0.82 to 0.96; P = 0.0024). A diagnosis of PAD on the waiting list was associated with an almost three-fold increase in the RR for death for patients without diabetes (2.98; 95% CI 2.71 to 3.27; P < 0.0001) and with diabetes (2.92; 95% CI 2.71 to 3.15; P < 0.0001). After transplantation, de novo PAD increased the RR for death almost two-fold in patients without diabetes (1.92; 95% CI 1.63 to 2.26; P < 0.0001) and with diabetes (1.83; 95% CI 1.58 to 2.12; P < 0.0001). The incidence of PAD is higher on the waiting list than after transplantation and is associated with an increased risk for death among patients with and without diabetes.
