Abstract

Background: While access and outcomes disparities for African American (AA) kidney transplant recipients are documented, there are limited studies assessing medication access disparities in transplantation. Cytomegalovirus (CMV) causes severe complications for transplant recipients, and we aimed to understand differences in access to CMV prophylaxis valganciclovir and its impact on CMV infection rates in AA transplant recipients.

Methods: This single-center, retrospective longitudinal cohort study examined high-risk (CMV serostatus D+/R-) adult kidney transplant recipients between June 1, 2010, and May 31, 202, through EMR abstraction. Standard univariate comparative statistics were employed alongside binary logistic regression for multivariable modeling.

Results: During the 10 year period, 418 kidney transplant recipients were included, with 179 (42.8%) identified as AA and 239 as non-AA. There were significant differences in mean age (p = 0.001) and private versus Medicaid insurance status (p < 0.001). AAs experienced higher death-censored graft loss rates (10.6% AA vs. 5.0% non-AA, p = 0.031). CMV infection rate, opportunistic infection rate, leukopenia incidence, and death did not differ significantly between AA and non-AA patients. AA patients were 42% less likely to receive valganciclovir out-of-pocket cost assistance compared to non-AA patients (OR 0.58, [0.379-0.892], p = 0.013). When incorporating age, Medicaid status, and donor marginality in a multivariable model, the impact of AA race on utilizing assistance programs became statistically non-significant (OR 0.70, [0.448-1.094], p = 0.118).

Conclusions: AAs were significantly less likely to leverage assistance programs or utilize personal resources to access valganciclovir. This disparity was partially explained by age, insurance status, and donor type. Despite this, CMV infection rates were similar between AA and non-AA cohorts.

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.
