BACKGROUND AND OBJECTIVES: IL-2 receptor antagonist (IL2-RA) is recommended as a
first-line agent for induction therapy in renal transplantation. However, this
remains controversial in deceased donor renal transplantation (DDRT) maintained
on tacrolimus (TAC)/mycophenolic acid (MPA) with or without steroids. DESIGN,
SETTING, PARTICIPANTS, & MEASUREMENTS: We studied the United Network for Organ
Sharing Registry for patients receiving DDRT from 2000 to 2012 maintained on
TAC/MPA at transplantation hospital discharge (n=74,627) to compare outcomes of
IL2-RA and other induction agents. We initially divided the cohort into two
groups on the basis of steroid use at the time of discharge: steroid (n=59,010)
versus no steroid (n=15,617). Each group was stratified into induction
categories: IL2-RA, rabbit antithymocyte globulin (r-ATG), alemtuzumab, and no
induction. The main outcomes were incidence of acute rejection within the first
year and overall graft failure (defined as graft failure and/or death)
post-transplantation. Propensity score (PS), specifically inverse probability of
treatment weight, analysis was used to minimize selection bias caused by
nonrandom assignment of induction therapies. RESULTS: Median (25th, 75th
percentiles) follow-up times were 3.9 (1.1, 5.9) and 3.2 (1.1, 4.9) years for
steroid and no steroid groups, respectively. Acute rejection within the first
year and overall graft failure within 5 years of transplantation were more common
in the no induction category (13.3%; P<0.001 and 28%; P=0.01, respectively) in
the steroid group and the IL2-RA category (11.1%; P=0.16 and 27.4%; P<0.001,
respectively) in the no steroid group. Compared with IL2-RA, PS-weighted and
covariate-adjusted multivariable logistic and Cox analyses showed that outcomes
in the steroid group were similar among induction categories, except that acute
rejection was significantly lower with r-ATG (odds ratio [OR], 0.68; 95%
confidence interval [95% CI], 0.62 to 0.74). In the no steroid group, compared
with IL2-RA, odds of acute rejection with r-ATG (OR, 0.80; 95% CI, 0.60 to 1.00)
and alemtuzumab (OR, 0.68; 95% CI, 0.53 to 0.88) were lower, and r-ATG was
associated with better graft survival (hazard ratio, 0.86; 95% CI, 0.75 to 0.99).
CONCLUSIONS: In DDRT, compared with IL2-RA induction, no induction was associated
with similar outcomes when TAC/MPA/steroids were used. r-ATG seems to offer
better graft survival over IL2-RA in steroid avoidance protocols.
