title: Post-transplant diabetes mellitus and methylprednisolone pharmacokinetics in African-American and Caucasian renal transplant recipients.
abstract: Post-transplant diabetes among renal transplant recipients is more prevalent in the African-American population. However, it is unknown if methylprednisolone (a commonly prescribed glucocorticoid in transplant patients) pharmacokinetics is altered among African-American renal allograft recipients compared to Caucasian counterparts. Therefore, the objectives of this study were to identify the occurrence of post-transplant diabetes in our clinic population and to characterize the pharmacokinetics of methylprednisolone among our African-American and Caucasian renal transplant recipients. A retrospective chart survey was done on African-American and Caucasian recipients with stable renal function and no history of diabetes pre-transplantation in order to characterize the occurrence of post-transplant diabetes in our clinical population. The survey was conducted from January 1985 to January 1992 in recipients with graft survival of at least 3 months. Post-transplant diabetes was defined as two fasting glucose serum concentrations greater than 140 mg/dl or one random serum glucose concentration greater than 200 mg/dl which was confirmed by a fasting serum glucose value greater than 140 mg/dl and a 2 hour post-prandial greater than 200 mg/dl. A 24-hour pharmacokinetic evaluation was conducted in a sub-group of African-American and Caucasian patients after intravenous administration of methylprednisolone. Over the survey period, 75 renal transplants (30 females; 45 males) were performed and 50 of these transplant recipients (24 females; 26 males) were not diabetic prior to the allograft placement. Of these 50 patients, 22 males and 17 females fulfilled the inclusion criteria established for the retrospective survey.(ABSTRACT TRUNCATED AT 250 WORDS)
