Surveillance of National Organ Transplant Recipients Affected by COVID-19

Surveillance of National Organ Transplant Recipients Affected by COVID-19 (SNO-TRAC)

The emergence of COVID-19 has had far-reaching implications for the public’s health and has been particularly impactful in vulnerable populations such as transplant recipients. Through a collaboration between Dr. Deepali Kumar and Tina Marinelli (transplant infectious disease specialist, UHN), the Canadian Society of Transplantation (CST), Canadian Blood Services, and the Canadian Donation and Transplantation Research Program (CDTRP), a registry was developed to capture data on all solid organ transplant recipients who contracted COVID-19 in Canada. The study is named SNO-TRAC (i.e., Surveillance of National Organ Transplant Recipients Affected by COVID-19).

Through this effort, we hope to provide the Canadian transplant community with timely information on the epidemiology, pathophysiology, clinical features, management, and prognosis of transplant recipients affected by COVID-19. The data also informs better approaches to prevention, treatment, and health policy and identifies knowledge gaps that can be the focus of future research.

All Canadian transplant centres were invited to participate in this important study. For those centres that can accommodate them, biospecimens (e.g., nasal swabs, bronchial washings, blood) are collected and banked to study viral pathogenesis, the immune response to SARS-CoV-2, and the role of co-infections on COVID-19 severity. Data from this study is hosted on this website and is updated as new data is shared.

Patients in this study are recipients of solid organ transplants who have been diagnosed with COVID-19. As of March 2021, 210 patients were enrolled into this study from six centers across three provinces. 

Participating programs include:

  • University Health Network (UHN)
  • Université Laval de Quebec (CHU)
  • Centre Hospitalier de l'Université de Montréal
  • Foothills Medical Centre (FMC)
  • Stollery Children's Hospital
  • St. Michael's Hospital (SMH)
