Among Patients with Pre-Transplant Donor-Specific Antibodies, the Disappearance of the Donor-Specific Antibodies at 3 Months is Not Associated with Less Rejection
S. Parajuli, A. Djamali, A. Kharel, B. Alzoubi, N. Bath, N. Garg, F. Aziz, D. Mandelbrot
University of Wisconsin, Madison, WI
*Purpose: The number of sensitized kidney transplant recipients (KTRs) are increasing on the waiting list. Some KTRs receive an organ in the presence of pretransplant…

Sensitized Lung Candidates Experience Reduced Access to Donor Organs
K. Lindblad¹, R. Goff², D. Stewart²
¹UNOS, Richmond, VA, ²UNOS, Richmnd, VA
