Tacrolimus Trough Concentration Variability and Disparities in African American Kidney Transplantation.

Background: Low tacrolimus concentrations have been associated with higher risk of acute rejection, particularly within African-American (AA) kidney transplant recipients; little is known about intrapatient tacrolimus variabilities impact on racial disparities. Methods: Ten year, single-center, longitudinal cohort study of kidney recipients. Intrapatient tacrolimus variability was assessed using the coefficient of variation (CV) measured between 1 month posttransplant and the clinical event, with a comparable period assessed in those without events. Pediatrics, nontacrolimus/mycophenolate regimens and nonrenal transplants were excluded. Multivariable Cox regression models were used to analyze data. Results: 1411 recipients were included (54.4% AA) with 39 521 concentrations utilized to assess intrapatient tacrolimus CV. Overall, intrapatient tacrolimus CV was higher in AAs vs non-AAs (39.9+/-19.8 % vs. 34.8+/-15.8% p40%) was a significant explanatory variable for disparities in AAs; the crude relative risk of acute rejection in AAs was reduced by 46% when including tacrolimus variability in modeling and reduced by 40% for graft loss. Conclusions: These data demonstrate that intrapatient tacrolimus variability is strongly associated with acute rejection in AAs and graft loss in all patients. Tacrolimus variability is a significant explanatory variable for disparities in AA recipients. Copyright (C) 2017 Wolters Kluwer Health, Inc. All rights reserved.
