A successful multidisciplinary research center depends on the quality of the science being conducted and the quality of the center's design, culture, infrastructure, and institutional support. In this perspective, we describe our experience building and maintaining a multidisciplinary transplant research center with a large focus on transplant infectious diseases. We identify principles that we believe contributed to our success including: taking inventory, defining culture, creating a multidisciplinary shared leadership model, establishing expertise in a multiple method approach, investing in operations and management, building and sharing resources, and securing institutional support.

Article Synopsis
  • HHV-8 (Kaposi sarcoma herpesvirus) is linked to serious illnesses including Kaposi sarcoma and lymphoproliferative disorders, particularly affecting transplant recipients.
  • A case study highlighted a fatal outcome linked to HHV-8, prompting a review of its impact on immunocompromised patients and exploring disease transmission and the importance of screening donors and recipients.
  • The study concludes that while HHV-8 diseases can be severe and multifaceted in transplant patients, the actual risk of donor-derived infections is not well understood and needs more research.

This commentary on a case argues that antimicrobial stewardship requires an intersectional disability justice approach if it is to be equitable, particularly for multiply marginalized patients with disabilities residing in nursing homes, who are more susceptible to antibiotic under- and overtreatment. Disability justice concepts emphasize resistance to structural and capitalist roots of ableism and prioritize leadership by disabled persons. A disability justice perspective on antimicrobial stewardship means prioritizing clarification of presumptive diagnoses of infection in vulnerable patients, clinician education led by disabled persons, and data collection.

Research involving recently deceased humans that are physiologically maintained following declaration of death by neurologic criteria-or 'research involving the recently deceased'-can fill a translational research gap while reducing harm to animals and living human subjects. It also creates new challenges for honouring the donor's legacy, respecting the rights of donor loved ones, resource allocation and public health. As this research model gains traction, new empirical ethics questions must be answered to preserve public trust in all forms of tissue donation and in the practice of medicine while respecting the legacy of the deceased and the rights of donor loved ones.

Immunogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is diminished in hematopoietic stem cell transplant (HSCT) recipients. To summarize current evidence and identify risk factors for attenuated responses, 5 electronic databases were searched since database inceptions through 12 January 2023 for studies reporting humoral and/or cellular immunogenicity of SARS-CoV-2 vaccination in the HSCT population. Using descriptive statistics and random-effects models, extracted numbers of responders and pooled odds ratios (pORs) with 95% confidence intervals (CIs) for risk factors of negative immune responses were analyzed (PROSPERO: CRD42021277109).

Approaches to pretransplant vaccination.

Curr Opin Organ Transplant

August 2022

Purpose Of Review: The aim of this study was to summarize new data and perspectives in pretransplant vaccination, with a particular focus on COVID-19 vaccination and vaccination requirements.

Recent Findings: Pretransplant vaccination produces superior markers of immunity and is expected to have greater clinical benefit, compared with posttransplant vaccination. As such, efforts are underway to identify and characterize barriers to pretransplant vaccination, with a particular focus on COVID-19 vaccine hesitancy.

Article Synopsis
  • This study examines how solid organ transplant (SOT) recipients respond to COVID-19 vaccinations, noting that they have reduced immune responses compared to the general population.!* -
  • Researchers reviewed a total of 83 studies and found that after multiple doses of mRNA vaccines, only 63.1% of SOT recipients developed a positive humoral immune response, indicating significant variability in effectiveness.!* -
  • Factors like older age were linked to poorer antibody responses, but some individuals who initially didn’t respond had an improvement after receiving a fourth vaccine dose.!*

Introduction: Most studies of solid organ transplant (SOT) recipients with COVID-19 focus on outcomes within one month of illness onset. Delayed mortality in SOT recipients hospitalized for COVID-19 has not been fully examined.

Methods: We used data from a multicenter registry to calculate mortality by 90 days following initial SARS-CoV-2 detection in SOT recipients hospitalized for COVID-19 and developed multivariable Cox proportional-hazards models to compare risk factors for death by days 28 and 90.

Transplant centers seeking to increase coronavirus disease 2019 (COVID-19) vaccine coverage may consider requiring vaccination for healthcare workers or for candidates. The authors summarize 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.
