This study investigates the prevalence of Trypanosoma cruzi infection among solid organ transplant recipients in the United States from 2019 to 2023 before transplantation. Utilizing data from a large multicenter network, we identified a rising seroprevalence of 4.8% from 1523 solid organ transplant recipients at the time of the evaluation for transplantation, particularly among lung and heart transplant recipients. The findings highlight the need for improved screening protocols to address...

Background Heart transplant (HT) remains the most frequently indicated therapy for patients with end-stage heart failure that improves prognosis in Chagas cardiomyopathy (CCM). However, the lack of benznidazole therapy and availability of RT-PCR follow-up in many centers is a major limitation to perform this life-saving intervention, as there are concerns related with the risk of reactivation. We aimed to describe the outcomes of a cohort of patients with CCM who underwent HT using a...

Chagas disease is a vector-borne infection caused by the protozoan Trypanosoma cruzi that is endemic in Latin America. More recently, the geographic distribution of the disease has changed due to immigration of asymptomatic infected individuals from endemic to non-endemic regions. Therefore, Chagas disease involving acute infection among negative recipients receiving a transplant graft from positive donors and reactivation episodes among positive recipients due to posttransplant...

These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of tissue and blood protozoal infections in the pre- and post-transplant period. Significant new developments in the field have made it necessary to divide the previous single guideline published in 2013 into two sections, with the intestinal parasites separated from this guideline devoted to tissue and blood protozoa. The...

Background Heart transplantation has been shown to be a safe and effective intervention for progressive cardiomyopathy from chronic Chagas disease. However, in the presence of the immunosuppression required for heart transplantation, the likelihood of Chagas disease reactivation is significant. Reactivation may cause myocarditis resulting in allograft dysfunction and the rapid onset of congestive heart failure. Reactivation rates have been well documented in Latin America; however, there is...

Although Trypanosoma cruzi, the parasite that causes Chagas disease, can be transmitted via organ transplantation, liver and kidney transplantation from infected donors may be feasible. We describe the outcomes of 32 transplant recipients who received organs from 14 T. cruzi seropositive donors in the United States from 2001 to 2011. Transmission was confirmed in 9 recipients from 6 donors, including 3 of 4 (75%) heart transplant recipients, 2 of 10 (20%) liver recipients and 2 of 15 (13%)...
