1Unidad de Parasitología, Facultad de Ciencias de la Salud, Universidad de Antofagasta, Chile.
Insights
This study investigated chronic Chagasic myocardiopathy in 40 autopsies. Three cases showed positive serology and cardiac muscle damage consistent with Trypanosoma cruzi, highlighting the need for routine pathological evaluation in endemic areas.
Area of Science:
- Pathology
- Infectious Diseases
- Cardiology
Background:
- Chagas disease (Chagas' disease) can lead to chronic chagasic myocardiopathy.
- Understanding the pathological basis of Chagas disease mortality is crucial in endemic regions.
Purpose of the Study:
- To investigate the serological and anatomopathological findings of Chagas disease in deceased individuals.
- To assess the role of Chagas disease as a cause of death in the Chilean endemic area.
Main Methods:
- Post-mortem serological testing using indirect immunofluorescence on pericardial fluid.
- Histopathological examination of cardiac muscle tissue.
- Macroscopic morphological study of cardiac tissue.
Main Results:
- Three out of 40 cases exhibited positive post-mortem Chagasic serology.
- Histopathology confirmed Trypanosoma cruzi-type damage in the cardiac muscle of positive cases.
- Macroscopic findings were not significantly relevant.
Conclusions:
- Routine anatomopathological studies are necessary to accurately determine Chagas disease as a cause of death.
- This study underscores the importance of integrating serological and pathological evaluations for Chagas disease mortality assessment.
- Further research is needed to refine diagnostic protocols for chronic Chagasic myocardiopathy in post-mortem examinations.
Abstract:
In order to contribute to a better knowledge of the chronic chagasic myocardiopathy, a post-mortem serological and anatomopathological study of Chagas' disease was carried out in 40 corpses. Between november 1987 and august 1988, autopsies were performed at the Pathological Anatomy Service of Antofagasta Regional Hospital and the Legal Medicine Section of the Ministry of Justice in Antofagasta. Positive postmortem chagasic serology, by using an indirect immunofluorescence test in pericardial fluid, was confirmed in three cases, among which the study of the histopathology of the cardiac muscle showed "Trypanosoma cruzi type" elements of the damage. The macroscopic morphological study did not show relevant findings. Results reveal the need to implement anatomopathological study systems for routines which contribute to evaluate the chagasic etiology as a cause of death among population of the endemic Chilean area.
