Abstract
The efficacy and safety of tacrolimus (FK506; Prograf) were determined in 28 adult kidney transplant patients (20 males and 8 females), aged 18–68 years (mean±S.D.: 46.9±4.03 years). Induction therapy was ATG-F ( n=23), daclizumab ( n=3), or none ( n=2), and maintenance immunosuppression consisted of tacrolimus, combined with mycophenolate mofetil (MMF; n=26) or azathioprine (AZA; n=2) and prednisone (Pred). In seven patients, cyclosporine A microemulsion (Neoral) was replaced by tacrolimus for acute rejection (AR; three patients), slow graft function (SGF, two patients) and Neoral side effects (two patients). Acute rejection occurred in five patients (17.8%), three of whom were steroid-resistant treated with a second course of ATG-F. Infection occurred in 10 patients (35.7%) with a total of 15 infectious episodes, comprising bacterial (73%) and viral (27%) infections related to CMV. Other side effects related to tacrolimus were hypertension in four patients (14%) and post-transplantation hyperglycemia in nine patients (32%), three of whom required insulin therapy. In addition, hypercholesterolemia and hypertriglyceridemia occurred in six (21%) and eight patients (28.5%), respectively. The patient’s hospital stay was 12.7±1.3 days (range: 8–24 days), and mean serum creatinine upon discharge, and at 1, 3 and 6 months following transplantation were: 2.1±0.5, 1.47±0.21, 1.41±0.53 and 1.23±0.11 mg/dl, respectively. The 6-month actuarial patient and graft survival rates were 100%. While tacrolimus is an effective calcineurin inhibitor for kidney transplantation (KT), severe acute rejection seen is related to highly sensitized patients, and the CMV infections noted were related to the presence of more CMV-negative recipients receiving kidneys from CMV-positive donors. Longer follow-up with a larger patient sample is needed to fully assess both the efficacy and safety of tacrolimus, including its metabolic effects.
