| Abstract: | BackgroundChronic renal dysfunction is present in about one quarter of kidney transplant patients at 1 year and in about 90% by 10 years. Nephrotoxicity caused by calcineurin inhibitors is among the most common factors. Elevated tacrolimus levels have been correlated with worse control of side effects including acute and/or chronic nephrotoxicity. The aim of this study was to observe the effects on graft function of conversion from the twice daily to the once daily extended release tacrolimus formulation in stable kidney transplant recipients within 5 years of grafting.MethodsThirty-one stable kidney transplant patients were converted at the same dosage (1 mg:1 mg). Patients served as their own controls based on results before versus after conversion.ResultsThe trough levels of tacrolimus showed a slight albeit significant reduction after the conversion. Serum creatinine and glomerular filtration rate showed a significant improvement without an association with the tacrolimus trough levels.ConclusionWe suggest that the immunosuppression with once daily tacrolimus may be a good option for kidney transplant patients. |
