title: Increased cardiovascular risk profile and mortality in kidney allograft recipients with post-transplant diabetes mellitus in Spain.
abstract: BACKGROUND
  Post-transplant diabetes mellitus (PTDM) is associated with poorer outcomes in kidney transplantation (KT) but little information exists about the evolution of traditional cardiovascular risk (CVR) factors under this disorder.
  
  
  METHODS
  We retrospectively analysed CVR factors at 3, 12 and 24 months of follow-up and mortality at three yr in 3365 KT performed in Spain during the years 1990, 1994 and 1998 with a functioning graft after the first year. Three groups were considered: (i) (PTDM, n, 251), (ii) diabetes mellitus as primary disease (DM, n = 156) and (iii) the remaining patients (controls, n = 2958).
  
  
  RESULTS
  Recipient age, weight and body mass index (BMI) were higher in PTDM than in the other groups (p < 0.0001), with a lower increase of body weight during follow-up (p < 0.003). PTDM patients showed higher total-cholesterol levels than controls at one (p < 0.01) and two yr (p < 0.0009), and higher triglyceride levels than the other groups during follow-up (p < 0.002). Compared with Controls, PTDM patients had significantly higher systolic blood pressure at one (p < 0.001) and two yr (p < 0.005). Diastolic blood pressure was higher in PTDM and controls (p < 0.001), while pulse pressure was higher in PTDM and DM patients (p < 0.0001) during follow-up. Using Cox proportional hazards analysis, PTDM correlated with total mortality (RR = 1.55; range 1.05-2.3; p < 0.02) but not with cardiovascular mortality.
  
  
  CONCLUSIONS
  In Spanish KT recipients with graft function after one yr, PTDM is associated with a worse traditional CVR profile and a higher overall mortality. Although short-term cardiovascular mortality remains similar, better control of CVR factors is mandatory to prevent long-term cardiovascular mortality inherent to this population.
