Abstract

BACKGROUND:

In a retrospective study of the first 75 primary renal transplant patients given alemtuzumab induction at our center, 20 were African American (27%), 32 were Hispanic (43%), and 23 were non-African American, non-Hispanic (31%).

METHODS:

Alemtuzumab was given intraoperatively and 4 days later (0.3 mg/kg), with planned low-dose maintenance mycophenolate mofetil (500 mg twice daily) and tacrolimus (targeted trough levels of 5 to 7 ng/ml) and no corticosteroid therapy after the first week. Median follow-up among ongoing survivors with a functioning graft was 45 months.

RESULTS:

Three-year actuarial patient and graft survival rates were 95% and 85% in African Americans, 89% and 78% in Hispanics, and 96% and 96% in non-African Americans, non-Hispanics, respectively (not significant). Bioavailability of tacrolimus was significantly lower among African Americans in comparison with the other patient subgroups (P<or=.002). While the incidence of biopsy-proven acute rejection was 20% (4/20) in African Americans, 19% (6/32) in Hispanics, and 13% (3/23) in non-African American, non-Hispanic (not significant), chronic allograft dysfunction occurred more frequently among African Americans (10/20) in comparison with Hispanics (8/32) and non-African American, non-Hispanics (8/23) (P=0.08, log-rank test). In addition, there was a trend at 6 and 12 months posttransplant for the mean serum creatinine to be less favorable among African American patients (P=0.08 and 0.07). No group had increased infection or malignancy.

CONCLUSIONS:

This immunosuppressive protocol appears reasonably safe for 3 years after renal transplantation but suggests higher incidences of biopsy-proven acute rejection, chronic allograft dysfunction, and borderline poorer renal function among African Americans in comparison with the other patient subgroups.
