PHILADELPHIA- Leading experts in transplant from Penn Medicine will converge in the Pennsylvania Convention Center in Philadelphia from June 1-5 for the American Transplant Congress. The event is the Joint Annual meeting of the American Society of Transplant Surgeons and the American Society of Transplantation.
Presenters at ATC2024
Below are some of the topics being presented by Penn experts this year:
Session: The Impact of Donor BMI on Safety and Outcomes in Living Donor Liver Transplantation: An Analysis of the National US Database
Nicolas Muñoz, MD, resident, National Clinician Scholars Program, and Therese Bittermann, MD, MSCE, assistant professor in Gastroenterology
Description: Donor obesity (BMI ≥ 30 kg/m2 ) poses a multifaceted challenge in the context of living donor liver transplantation (LDLT) by reducing the potential donor pool and impacting donor safety and outcomes. We utilized the United Network for Organ Sharing (UNOS) database to evaluate the impact of donor obesity on donor safety and recipient outcomes in LDLT.
Time and Place: Sunday, June 2, 2024 at 9:15am in Poster Hall, Exhibit Hall A, Level 2
Session: Transfers of Deceased Organ Donors after Brain Death to United States Donor Care Units
Emily Vail, MD, MDc, assistant professor of Anesthesiology and Critical Care
Description: Use of deceased organ donor care units (DCUs) requires transportation of donors from hospitals to DCUs. Longer transport distances may incur higher costs or increase risk of clinical decompensation during transport. Vail’s study aimed to 1) describe geographic patterns of donor transfer to operating DCUs in the US and 2) determine whether distances between donor hospitals and DCUs are associated with the likelihood of donor transfer.
Time & Place: Sunday, June 2, 2024 at 9:15am in Poster Hall, Exhibit Hall A, Level 2
Session: The first steps for pig liver xenograft to human implementation
Abraham Shaked, MD, PhD, Eldridge L. Eliason Professor of Surgery
Description: Dr. Shaked discuses initial results from a research study at the Perelman School of Medicine at the University of Pennsylvania- which marked a milestone in the quest for a more effective option to “bridge” critically ill patients to liver transplant. In December 2023, the research team announced the first successful completion of an experiment to circulate a recently deceased donor’s blood through a genetically engineered pig liver outside their body – an effort they plan to study further in hopes of providing options to save more patients from dying while waiting for transplants.
Time & Place: Monday, June 3, 2024 at 2:10pm in Room 116 Level 1
Session: Regulatory T Cell Expansion and Prolongation of Cardiac Allograft Survival Using Lipid Encapsulated Messenger RNA Encoding Foxp3
Wayne William Hancock, MD, PhD, FRCPA, professor of Pathology and Laboratory Medicine
Description: Many investigators have focused their attention on manipulation of T-regulatory (Treg) cells to improve transplant outcomes. Strategies reported include use of Treg adoptive cell therapy (engineered T cells or CAR-Tregs); Treg expansion using IL-2 modified to promote its stability and half-life and/or selectivity for the IL-2R alpha chain preferentially expressed by Treg cells under basal conditions; and pharmacologic agents such as certain HDAC inhibitors that increase Foxp3 production, acetylation and transactivation. However, nucleic acid-based approaches have not been reported. Since, the transcription factor, Foxp3, is essential for the production, proliferation and survival of T-regulatory (Treg) cells, we tested whether delivery of Foxp3 mRNA to host T cells could expand the Treg population and promote allograft survival.
Time & Place: Tuesday, June 4, 2024 at 9:15am in Poster Hall, Exhibit Hall A, Level 2
Session: Interventions to improve early transplant outcomes
Marina Serper, MD, MS, associate professor in Gastroenterology
Time & Place: Tuesday, June 4, 2024 at 1:30pm in Room 117, Level 1
