Just Released - Transplantation Direct - March Issue

The March issue of Transplantation Direct is now online. This issue features several topics across a wide span of transplantation research. We have letter communications on experiences combining standard DSA testing with protocol pancreas biopsies in pancreas transplant recipients, characterization of kidney injury using donor-derived cell-free DNA testing, and a method for urinary tract reconstruction in experimental embryonic kidney transplants in pigs. Also, we have review articles on the impact of immunosuppression treatment on SARS-CoV2-infected kidney transplant recipients, and on the use of mHealth Apps in solid organ transplant recipients. There are research articles on reconsidering the weight of HLA matching versus non-allogenic factors in kidney transplantation. The practice and acceptability of re-transplanting patients with recurrent alcohol-associated liver disease is critically assessed, with recommendations. In lung transplantation, there are new reports on COVID-19 outcomes in transplant recipients, and on the association of gastroesophageal reflux immune activation with CLAD development. Case reports are presented on acute severe heart transplant dysfunction associated with microvesicular steatosis, and on the use of plasma microbial cell-free DNA next-generation sequencing to diagnose Mycobacterium kansasii infections in transplant recipients. Please find complete article details with open access on our Transplantation Direct website.

In Memoriam - Samuel Strober

We are sad to announce the passing of Samuel Strober, a friend and colleague.

Samuel Strober, MD, passed away at his home in California on Friday, February 11th. Sam was a friend to many of us and a giant in the field of allograft tolerance induction. He was a Professor of Medicine at Stanford University and remained dedicated to his professional goals until the time of his death from multiple myeloma. Sam devoted his career to the translation of his pioneering work in rodents using total lymphoid irradiation and anti-lymphocyte serum to achieve stable mixed chimerism without graft-vs-host disease into a protocol that can be applied to adult human organ transplant recipients. This clinical protocol was first applied successfully, with minimal GVHD, in patients with hematologic malignancies and later developed for the purpose of kidney allograft tolerance, with durable mixed chimerism and permanent graft survival off immunosuppression in HLA-identical donor-recipient pairs. He published hundreds of papers, received numerous honors and awards and will be sorely missed by his friends and colleagues in the transplantation community.

New Report Recommends Changes to U.S. Organ Transplant System to Improve Fairness and Equity, Reduce Nonuse of Donated Organs, and Improve the System’s Overall Performances

WASHINGTON — A new report from the National Academies of Sciences, Engineering, and Medicine finds the U.S. organ transplant system to be demonstrably inequitable; significant nonuse of donated organs — approximately 1 in 5 kidneys from deceased donors are not used; and unexplained variation in performance across the system. The report makes recommendations to address racial and other disparities, reduce nonuse of donated organs, and reduce or eliminate variations in the performance of transplant centers and organ procurement organizations.

Supported by

Early in his career, Dr. Starzl recognized the importance of deceased donation. He pioneered many facets of transplantation, including immunosuppressive drug development, organ preservation, tissue matching, surgical transplant technology, and developed the team approach to organ transplantation; thus paving the way for the success and acceptance of heart, lung, pancreas, intestinal, liver, and kidney transplantation. The international impact of the fruits of seven decades of commitment to transplantation is shown by estimates of over 600 000 Americans and millions of patients around the world that have received a life-saving organ transplantation. He was also credited as having trained over 1,000 medical and surgical transplant specialists over his 50 years in clinical medicine, many of whom have gone on to successfully develop their own transplant
