Abstract
Background: Several studies have suggested an increased risk of cytomegalovirus (CMV) viremia among Hepatitis C virus (HCV)-uninfected recipients of kidney transplants from HCV-RNA+ deceased donors (HCV D+/R-), but these studies featured small sample sizes and limited ability to address confounding variables.
Methods: We assembled a retrospective cohort of adult kidney transplant recipients at five US centers between 4/1/2015 and 12/31/2020 to determine the association between HCV D+/R- transplants and the outcomes of CMV viremia (> 1000 IU/mL), death-censored graft failure, and mortality in the first posttransplant year compared to HCV D-/R- transplants. We generated highly similar matched cohorts of HCV D+/R- and HCV D-/R- recipients based on attributes that affect the risk of CMV viremia. We matched exactly on center, CMV donor/recipient serostatus, and antibody induction therapy.
Results: The cohort comprised 275 HCV D+/R- recipients with a mean age of 52.5 years (SD = 10.7); 19% were CMV D+/R-, and 74% received anti-thymocyte globulin induction. With variable ratio matching, 267 HCV D+/R- recipients were matched to 996 HCV D-/R- recipients. CMV viremia occurred in 15% of HCV D+/R- and 11% of HCV D-R- recipients. In Cox regression, transplantation with an HCV-RNA+ donor kidney was not associated with a significantly higher risk of CMV viremia (HR 1.3, 95% CI 0.89-1.92) or death-censored graft loss (HR 0.61, 95% CI 0.31-1.2).
Conclusion: The risk of CMV viremia was not significantly increased among HCV D+/R- kidney recipients. Future studies should examine associations between donor-derived HCV infection and clinical outcomes of CMV syndrome and disease.
期刊介绍：
Transplant Infectious Disease has been established as a forum for presenting the most current information on the prevention and treatment of infection complicating organ and bone marrow transplantation. The point of view of the journal is that infection and allograft rejection (or graft-versus-host disease) are closely intertwined, and that advances in one area will have immediate consequences on the other. The interaction of the transplant recipient with potential microbial invaders, the impact of immunosuppressive strategies on this interaction, and the effects of cytokines, growth factors, and chemokines liberated during the course of infections, rejection, or graft-versus-host disease are central to the interests and mission of this journal.
Transplant Infectious Disease is aimed at disseminating the latest information relevant to the infectious disease complications of transplantation to clinicians and scientists involved in bone marrow, kidney, liver, heart, lung, intestinal, and pancreatic transplantation. The infectious disease consequences and concerns regarding innovative transplant strategies, from novel immunosuppressive agents to xenotransplantation, are very much a concern of this journal. In addition, this journal feels a particular responsibility to inform primary care practitioners in the community, who increasingly are sharing the responsibility for the care of these patients, of the special considerations regarding the prevention and treatment of infection in transplant recipients. As exemplified by the international editorial board, articles are sought throughout the world that address both general issues and those of a more restricted geographic import.
