This review highlights Chagas disease risks in immunosuppressed patients, particularly organ transplant recipients and those with HIV. Early detection and treatment are crucial for managing acute transmission and reactivation of chronic infections.
Area of Science:
- Immunology
- Infectious Diseases
- Transplantation
Background:
- Chagas disease (Chagas) poses risks for immunosuppressed individuals, including organ transplant recipients and HIV-infected patients.
- Reactivation or acute transmission can occur in these vulnerable populations.
Purpose of the Study:
- To review recent literature on Chagas disease in immunosuppressed hosts.
- To outline risks, diagnostic strategies, and treatment approaches.
Main Methods:
- Literature review of recent studies on Chagas disease in immunosuppressed patients.
- Analysis of transmission rates, clinical manifestations, and treatment outcomes.
Main Results:
- Organ transplantation from Trypanosoma cruzi-infected donors can lead to transmission (kidney: 18-19%, liver: 29%).
- Reactivation in heart transplant recipients may mimic rejection; in HIV patients, it can cause meningoencephalitis or myocarditis.
- Prospective monitoring effectively detects acute infection before symptoms, enabling early, effective treatment.
Conclusions:
- Heart transplantation from T. cruzi-infected donors is contraindicated; other organs may be considered.
- Prospective monitoring for at least 6 months post-transplant is recommended over prophylaxis.
- Treatment involves benznidazole or nifurtimox, with immune reconstitution for HIV-coinfected patients; secondary prophylaxis needs further study.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
