Understanding the Initial Rise in Kidney Discard Rates Observed Post-KAS.
D. Stewart,¹ A. Kucheryavaya,¹ R. Brown,¹ D. Klassen,¹ N. Turgeon,² M. Aeder.³
¹UNOS, Richmond, VA; ²Emory Univ, Atlanta, GA; ³Univ Hosp Case Med Ctr, Cleveland, OH.
Background: Kidney discard rates increased by 10% -- from 18.3% to 20.2% (p=0.001) -- during the first 7 months of KAS but returned to pre-KAS…

Rapamycin (RPM) Synergizes with CD154 mAb and DST to Promote Long-Term Vascularized Composite Allograft (VCA) Survival, but Prevents Induction of Donor-Specific Tolerance.
L. Wang, Z. Wang, R. Han, T. Bhatti, L. Levin, M. Levine, W. Hancock.
CHOP & UPenn, Philadelphia.
Even though CD154 mAb (MR-1) plus donor splenocyte transfusion (DST) is very effective at inducing tolerance of various allografts, such as those of hearts, kidneys…
