Abstract

BACKGROUND: This large, randomized, multicenter trial evaluated if basiliximab induction and delayed tacrolimus can preserve renal function in older kidney transplant patients. METHODS: Patients aged 60 years and older received delayed tacrolimus with basiliximab and mycophenolate mofetil with early steroid discontinuation (Tac-d, n=132) or standard tacrolimus with mycophenolate mofetil and steroids until day 91 (Tac-s, n=122). Tacrolimus trough levels were 5 to 10 ng/mL after day 43 in both groups. Renal function at month 6 was measured by calculated creatinine clearance (Cockcroft-Gault formula). RESULTS: In both groups, mean recipient age was 66 years, mean donor age was 63 years with 73% of donors aged 60 years and older. Steroid discontinuation was slower than protocol specified. In the Tac-d group, 56.1% were steroid free at day 14 and 81.8% at month 6. In the Tac-s group, 37.7% were steroid free at month 4 and 63.9% at month 6. Mean (+/-SD) calculated creatinine clearance was 45.7+/-16.1 mL/min (Tac-d) and 45.0+/-18.2 mL/min (Tac-s) (P=ns), mean glomerular filtration rate (modified diet in renal disease formula) was 44.9+/-16.2 mL/min and 41.6+/-16.8 mL/min, respectively. Incidences of biopsy-proven acute rejection were 18.9% (Tac-d) and 18.0% (Tac-s). Delayed graft function was 30.3% (Tac-d) and 23.8% (Tac-s). Estimated patient survival rates (Kaplan-Meier) in the Tac-d and Tac-s groups were 96.1% vs. 99.2% and estimated graft survival rates were 90% vs. 87.6%, respectively. Safety results were similar with both regimens. CONCLUSION: Delayed tacrolimus with basiliximab induction did not provide an advantage in preserving renal function or reducing delayed graft function in older kidney transplant patients.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
