Immunosuppression with low-dose daclizumab in liver transplant recipients with impaired kidney function: a single-center experience.
BACKGROUND
Nephrotoxicity of calcineurin inhibitors (CNI) may exert detrimental effects, particularly in orthotopic liver transplantation (OLT) patients with impaired kidney function. Immunosuppression with daclizumab permits delayed introduction of CNI, and may be preferred for patients with kidney dysfunction. This retrospective analysis of our experience using daclizumab was performed among patients who underwent transplantation with impaired kidney function.


METHODS
We analyzed 168 patients. A serum creatinine (Cr) level >1.5 mg/dL was the indication for a protocol with low-dose daclizumab (50 mg intravenous [IV], day 0 and day 4), mycophenolate mofetil (MMF; 500 mg twice daily IV/orally), and tapering doses of prednisolone from day 0 after OLT. CNI were introduced at day 4-15 after OLT. Patients with a Cr level <1.5 mg/dL received immunosuppression with CNI+MMF+steroids or CNI+steroids.


RESULTS
Fourteen patients fulfilled the criterion for daclizumab immunosupression. Their Cr and creatinine clearance (CrCl) values at OLT were 2.85 +/- 1.22 mg/dL and 19 +/- 11 mL/min, respectively. In the remaining 154 patients, Cr and CrCl results were 0.88 +/- 0.3 mg/dL and 107 +/- 82 mL/min, respectively. At discharge, the daclizumab group showed Cr and CrCl estimates of 0.97 +/- 0.45 mg/dL and 86 +/- 34 mL/min (P < .0001 for both, when compared with prior to OLT). Both Cr and CrCl levels at discharge were not different from those values of patients who underwent transplantation with normal kidney function. The incidence of acuterejection was 14% in the daclizumab group and 18% in the other recipients (P = not significant [NS]).


CONCLUSIONS
Immunosuppression with low-dose daclizumab and delayed introduction of CNI was safe and did not increase the risk of an acute rejection episode, thus offerring an excellent therapeutic option for patients who undergo transplantation with impaired kidney function.
