Abstract
Background: Antibody-mediated rejection (AMR) is an important cause of kidney transplant loss. A new strategy requiring application of precision medicine tools in transplantation considers molecular compatibility between donors and recipients and holds the promise of improved immunologic risk, preventing rejection and premature graft loss.
Objective: The objective of this study was to gather patients' and caregivers' perspectives on molecular compatibility in kidney transplantation.
Design: Individual semi-structured interviews.
Setting: The Centre hospitalier de l'Université de Montréal (CHUM) and McGill University Health Centre (MUHC) kidney transplant programs.
Participants: Kidney transplant candidates, kidney transplant recipients, and caregivers.
Methods: Twenty-seven participants took part in semi-structured interviews between July 2020 and November 2021. The interviews were digitally recorded, transcribed, and analyzed using the qualitative description approach.
Results: Participants had different levels of knowledge about the kidney allocation process. They expressed trust in the system and healthcare professionals. They indicated that a fair organ allocation system should strive to maximize graft survival as it would decrease the demand for deceased donor kidneys and allow more patients to access transplantation. Molecular matching and precision medicine were seen as important improvements in the kidney transplant allocation process given their potential to improve graft survival and decrease the need for retransplantation. However, participants were concerned about increased waiting times that may negatively impact some patients upon implementation of molecular matching. To address these concerns, participants suggested integrating safeguards in the form of maximum waiting time for molecularly matched kidneys.
Limitations: This study was conducted in the province of Quebec most of the participants were white and highly educated. Consequently, the results could not be generalizable to other populations, including ethnic minorities.
Conclusions: Molecular matching and precision medicine are viewed as promising technologies for decreasing the incidence of AMR and improving graft survival. However, further studies are needed to determine how to ethically integrate this technology into the kidney allocation scheme.
期刊介绍：
Canadian Journal of Kidney Health and Disease, the official journal of the Canadian Society of Nephrology, is an open access, peer-reviewed online journal that encourages high quality submissions focused on clinical, translational and health services delivery research in the field of chronic kidney disease, dialysis, kidney transplantation and organ donation. Our mandate is to promote and advocate for kidney health as it impacts national and international communities. Basic science, translational studies and clinical studies will be peer reviewed and processed by an Editorial Board comprised of geographically diverse Canadian and international nephrologists, internists and allied health professionals; this Editorial Board is mandated to ensure highest quality publications.
