Filter by:After Campath induction, followed with kidney transplantation, patients will be randomly assigned to receive either tacrolimus or cyclosporine microemulsion in combination with mycophenolates. Patients will be followed including protocol biopsy at 1, 12, 36, 60 month posttransplant, regular nuclein acid testing (NAT) for cytomegalovirus (CMV), Epstein-Barr virus (EBV) and BK virus (BKV) in urine and blood. The investigation is undertaken to clarify the reason for equal survival rates for patients on cyclosporine and tacrolimus despite the lower rejection rate on tacrolimus.
The objective of this study is to examine the effect on allograft function and histology of converting African American renal transplant recipients with chronic allograft nephropathy (CAN) from a tacrolimus-based regimen to a sirolimus-based maintenance immunosuppression regimen. The investigators hypothesize that the conversion from tacrolimus to sirolimus in African American renal recipients will stabilize or improve renal allograft function, and stabilize the histological progression of CAN. This conversion will have the potential to prolong long-term graft survival in African American renal transplant patients. GFR measurements, histological parameters on the allograft biopsy, as well as patient and graft survival, incidence of acute rejection, and specific side effects will be monitored and compared between the sirolimus conversion group and the patients who will be maintained on tacrolimus.
The purpose of this trial is to ascertain whether the withdrawal of calcineurin inhibitors (CNI) will lead to less kidney transplant damage when compared with minimisation. The investigators will assess this by comparing the degree of damage on kidney biopsies taken before and after minimisation/withdrawal of CNI.
