title: The increased risk of post-transplant diabetes mellitus in peritoneal dialysis-treated kidney allograft recipients.
abstract: BACKGROUND
  Post-transplant diabetes mellitus (PTDM) is a common metabolic complication in kidney allograft recipients, significantly contributing to the elevated cardiovascular morbidity after renal transplantation and increased risk of chronic transplant dysfunction. The aim of the present investigation was to evaluate the factors influencing PTDM development. Under particular consideration were the elements, existing before the transplantation, especially the modality of dialysis treatment significance, i.e. haemodialysis (HD) versus peritoneal dialysis (PD).
  
  
  METHODS
  Three hundred and seventy-seven consecutive outpatients who underwent renal transplantation (RTx) in our institution between January 2003 and December 2005 were analysed. PTDM was diagnosed according to the current American Diabetic Association/World Health Organization criteria. Statistical inference was conducted by means of univariate methods (one factor versus PTDM) and multivariate methods in frames of generalized linear model.
  
  
  RESULTS
  In the study group, 72 patients (23.4%) developed PTDM after RTx (55 HD and 17 PD patients). PTDM incidence at 3, 6 and 12 months was 15.9%, 22.1% and 23.4%, respectively. The mean interval from transplantation to the onset of PTDM was 3.08 ± 2.73 months. In univariate analysis, the factors associated with the elevated risk of PTDM appearance were older recipient age, positive family history of diabetes, hypertensive nephropathy as end-stage renal disease cause, higher body mass index at transplantation, treatment by PD, and the graft from an older donor. In multivariate verification, statistical significance remained: older recipient age (P < 0.001), positive family history of diabetes (P = 0.002), and treatment by PD (P = 0.007).
  
  
  CONCLUSIONS
  Treatment by PD appears to be a possible novel factor, not yet reported, which may increase the risk of PTDM development.
