title: Analysis of posttransplant diabetes mellitus prevalence in a population of kidney transplant recipients.
abstract: OBJECTIVE
  The onset of posttransplant diabetes mellitus (PTDM) among kidney recipients is associated with an increased risk of graft failure and death. Minimizing the risk of PTDM is a priority for long-term improvement in survival rates. We sought to evaluate the prevalence of PTDM and impaired fasting glucose (IFG) among a population of kidney transplant recipients to identify the risk factors and to evaluate graft and patient survivals.
  
  
  METHODS
  We analyzed 250 consecutive Caucasian patients who received kidney allografts in our center between May 2000 and December 2005, with a median follow-up of 32 months (range, 1-78 months).
  
  
  RESULTS
  We observed altered glucose metabolism in 17% of patients; specifically, the prevalences of PTDM and IFG were 12.2% and 4.8%, respectively. Patients who developed PTDM or IFG were overweight (BMI, 26.4+/-3.4 and 28.1+/-3.4 kg/m(2), respectively), whereas the normal glucose (NG) group's BMI was 23.8+/-3.5 kg/m(2) (P= .002 and P= .004, respectively). Prevalence of acute rejection was higher in the PTDM and IFG patients compared with the NG patients (60.7%, 63.6%, and 32.1%, respectively; P= .006; P< .04), while no difference was observed in terms of graft and patient overall survival.
  
  
  CONCLUSIONS
  In our series of patients, we showed that being overweight represents a major risk factor for the development of PTDM, which results in an increased acute rejection rate. These results confirmed the importance of appropriate weight control among patients undergoing kidney transplantation, which should also be strictly monitored for all risk factors associated with the development of impaired glucose metabolism.
