The dynamics of glucose metabolism under calcineurin inhibitors in the first year after renal transplantation in nonobese patients.

Background: The incidence of glucose metabolism disturbances after transplantation often is based on the use of hypoglycemic agents and not on the results of glucose tolerance tests (GTTs), which may camouflage the real incidence. A lack of information also exists regarding the profile of glucose metabolism during the first year after transplant.

Methods: Oral GTT along with insulin measurements and drugs pharmacokinetics were prospectively performed at days 30, 60, 180, and 360 after transplant to diagnose disturbances of glucose metabolism after renal transplantation, in nonobese patients receiving either tacrolimus (n=55) or cyclosporine (n=29), along with mycophenolate mofetil and steroids.
