Insights

Organ transplantation from Trypanosoma cruzi (Chagas disease) positive donors may be safe for liver and kidney recipients. Close monitoring and prompt treatment significantly reduce transmission risks and prevent symptomatic disease.

Area of Science:

  • Transplant Surgery
  • Infectious Diseases
  • Parasitology

Background:

  • Trypanosoma cruzi (T. cruzi) transmission via organ transplantation poses a risk for Chagas disease.
  • Limited data exist on the feasibility of liver and kidney transplantation from T. cruzi-seropositive donors.

Purpose of the Study:

  • To evaluate the outcomes of liver and kidney transplant recipients who received organs from T. cruzi-seropositive donors.
  • To assess the effectiveness of post-transplant monitoring protocols in preventing T. cruzi transmission.

Main Methods:

  • Retrospective analysis of 32 transplant recipients from 14 T. cruzi-seropositive donors in the US (2001-2011).
  • Documented transmission rates based on donor seropositivity and recipient monitoring.
  • Compared outcomes between recipients with and without complete T. cruzi monitoring (PCR, hemoculture, serology).

Main Results:

  • Transmission occurred in 9 of 32 recipients (28%), with higher rates in heart (75%) vs. liver (20%) and kidney (13%) recipients.
  • Recipients with no or incomplete monitoring had a higher incidence of confirmed transmission (5/13) and symptomatic disease (4/5).
  • Recipients with consistent monitoring showed lower transmission rates (4/19) and no symptomatic cases.

Conclusions:

  • Liver and kidney transplantation from T. cruzi-seropositive donors can be feasible with rigorous post-transplant monitoring.
  • Adherence to recommended monitoring schedules (PCR, hemoculture, serology) is crucial for early detection and management.
  • Prompt benznidazole therapy can mitigate the risk of symptomatic Chagas disease following transplantation.
