Abstract

Background: Multiple outpatient therapies have been developed for COVID-19 in high-risk individuals, but solid organ transplant (SOT) recipients were not well represented in controlled clinical trials. To date, few comparative studies have evaluated outcomes between outpatient therapies in this population.

Methods: We performed a retrospective cohort study using de-identified administrative claims data from OptumLabs Data Warehouse. Patients were included if they were age ≥ 18 years, diagnosed with COVID-19 between January 2022 and December 2023, and underwent SOT prior to COVID-19. The primary outcome was 30-day hospitalization. Stabilized inverse probability of treatment weighting was used to account for potential confounding variables.

Results: 4192 SOT recipients with COVID-19 were identified. 1403 received an outpatient COVID-19 therapy, including anti-spike monoclonal antibodies (N = 748, 53.3%), molnupiravir (N = 327, 23.3%), ritonavir-boosted nirmatrelvir (N = 217, 15.5%), or remdesivir (N = 141, 10.0%). In weighted analysis compared to no treatment, anti-spike monoclonal antibodies (hazard ratio [HR] 0.39, 95% confidence interval [CI] 0.28-0.55; p < 0.001), molnupiravir (HR 0.56, 95% CI 0.36-0.89; p = 0.013), and nirmatrelvir (HR 0.47, 95% CI 0.25-0.89; p = 0.020) were associated with reduced hospitalization risk, while remdesivir (HR 1.00, 95% CI 0.50-1.98; p = 0.992) was not. Hospitalization rates were similar between the treatment agents, apart from remdesivir showing a higher risk compared to anti-spike monoclonal antibodies.

Conclusions: Outpatient COVID-19 therapies were largely associated with improved outcomes among SOT recipients. These treatment agents showed similar rates of 30-day hospitalization, except for remdesivir. The choice of outpatient COVID-19 therapy in SOT recipients should primarily account for patients' individual circumstances and drug-drug interactions rather than differential therapeutic efficacy.

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.
