<qa>  What is the incidence of PTDM?1.2.2 Calcineurin inhibitors Calcineurin inhibitors have also been associated with post transplant diabetes. The incidence of PTDM has been reported to be more than 30 depending on the calcineurin inhibitor used, Cyclosporine vs. Prograf, trough level, race, and risk factors for diabetes all contribute to this number. These figures may underestimate the true incidence of PTDM, as most studies have not utilized the strict criteria of the ADA for diagnosis of diabetes. Most studies report a higher incidence of PTDM with the use of Prograf compared to Cyclosporine. The greater diabetogenicity of Prograf has been confirmed in a recent study investigating the new onset of diabetes both before and after kidney transplant.14 this study revealed that the incidence of new-onset diabetes was 70 higher in Prograf treated patients than with patients receiving Neoral.16 This contrasts with studies mentioned above where Prograf is used in steroid free protocols with no or very low incidence of post transplant diabetes.
