Many members have inquired about the AST's role, engagement, and impact in addressing the ongoing and quite-fluid HHS-HRSA OPTN modernization process. Rest assured that your Society has been, and continues to be, at the table with HHS, HRSA, Congress, patients, and the stakeholder community from day one. The AST has worked diligently from the very beginning to strategically position the Society to keep the door open for engaging our government partners and all stakeholders throughout the modernization initiative.

The AST has submitted a letter to HHS Secretary Robert F. Kennedy, Jr., urging the administration to reconsider proposed NIH funding reductions that could hinder critical transplant research. Cutting support for essential infrastructure may slow advancements in organ availability, transplant survival, and innovative treatments. Read our full letter to learn more.

The AST is pleased to announce its call for nominations for the 2025 Achievement Awards.

Each year, the AST honors its members’ accomplishments and contributions to the field of transplantation through the Achievement Awards. Members are recognized at different levels of their careers with Basic Science Awards, Clinical Science Awards, and Distinguished Career Awards.

The heterogeneous clinical presentation of graft microvascular inflammation poses a major challenge to successful kidney transplantation. The effect of microvascular inflammation on allograft outcomes is unclear.

Lung transplant candidates who are highly sensitized against human leucocyte antigen have a lower likelihood of graft allocation and a higher risk of dying while on the waiting list. C1-esterase inhibitor, an inhibitor of the classical and lectin pathways of complement activation, has been used successfully to prevent and treat acute antibody-mediated rejection in kidney and heart transplantation.

Calcineurin inhibitors have been the choice for maintenance immunosuppression (IS) in kidney transplant recipients (KTR), but they are associated with nephrotoxicity and metabolic side effects.
