Statement of The Transplantation Society’s support to the people of Ukraine.

As the global leader in transplantation, committed to health and life for all, The Transplantation Society expresses grave concern over the escalating violence and humanitarian crisis in Ukraine.

The protection of civilians and preservation of healthcare is imperative. TTS stands ready to support our colleagues, friends, families and patients impacted by this tragedy. As a non-State actor in official relations with the World Health Organization, we will seek collaborate with the WHO to provide our expert assistance on the Ukraine emergency

We are monitoring the situation and have setup a donation page ( to collect funds to be distributed to support the maintenance of healthcare in the Ukraine and assist transplant patients as may be possible. We will also reach out to contacts to assess how we can assist to re-establish transplantation activities once the crisis has ended. TTS will match each contribution, dollar for dollar, up to $50,000 USD in total.

Individuals may also contribute to the WHO foundation directly using this link:

'World-first' heart-thymus transplant success for Easton

March 9 - North Carolina, USA

Duke University doctors say a baby is thriving after a first-of-its-kind heart transplant -- one that came with a bonus technique to try to help prevent rejection of the new organ.

Easton Sinnamon of Asheboro, North Carolina, received his unique transplant last summer when he was 6 months old. But Duke waited to announce it until Monday after doctors learned the specially processed thymus implants appear to be functioning like they'd hoped -- producing immune cells that don't treat the tot's new heart like foreign tissue.

COVID Vax Effectiveness Quantified in Immunosuppressed Patients

"Booster doses are effective and important for individuals on immunosuppressants," corresponding author Lili Zhao, PhD, told Medscape Medical News. "Previous studies focused mostly on the Pfizer vaccine, whereas our study is the first that also investigates the Moderna vaccine in a large, immunosuppressed population." Zhao is a research associate professor in biostatistics at the University of Michigan, Ann Arbor.

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

Whole genome sequencing reveals host factors underlying critical Covid-19.

Kousathanas A et al.
Nature. 2022 Mar 7. doi: 10.1038/s41586-022-04576-6. PMID: 35255492

This study analyzed whole genome sequencing in 7,491 critically ill cases compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical Covid-19. 16 new independent associations, including variants within genes involved in interferon signaling (IL10RB, PLSCR1), leucocyte differentiation (BCL11A), and blood type antigen secretor status (FUT2) were identified. Reduced expression of a membrane flippase (ATP11A), and increased mucin expression (MUC1), in critical disease were identified. These results were broadly consistent with a multi-component model of Covid-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication, or an enhanced tendency towards pulmonary inflammation and intravascular coagulation.

Ethical review of COVID-19 vaccination requirements for transplant center staff and patients.

Kates OS et al.
Am J Transplant. 2022 Feb;22(2):371-380. doi: 10.1111/ajt.16878. PMID: 34706165

This review article summarizes current data to inform an ethical analysis of the harms, benefits, and individual and societal impact of mandatory vaccination, concluding that vaccine requirements for healthcare workers and transplant candidates are ethically justified by beneficence, net utility, and fiduciary duty to patients and public health. Implementation strategies should mitigate concerns about respect for autonomy and transparency for both groups.
